Toimintatutkimus tietokoneavusteisten opetusohjelmien hyödynnettävyydestä ammatillisessa koulutuksessa sähköalalla

Tutkimuksen tavoitteena oli tutkia tietokoneavusteisen opetuksen opetusmenetelmänä ja tietokoneavusteisten opetusohjelmien oppimateriaalina soveltuvuutta erilaisiin sähköalan ammatillisiin opetus- ja oppimistilanteisiin. Tietokoneavusteisilla opetusohjelmilla tarkoitetaan tässä tutkimuksessa erilaisia digitaaliseen muotoon tallennettuja oppimateriaaleja ja tietokoneavusteisella opetuksella näiden digitaalisten oppimateriaalien hyödyntämistä erilaisissa oppimistilanteissa. Opetusteknologian kehittymisen myötä myöskin opettajin valittavissa olevat opetusmenetelmät lisääntyvät ja monipuolistuvat. Vastaavalla tavalla myöskin oppimateriaalit kehittyvät ja mahdollistavat oppijan näkökulmasta entistä yksilöllisemmät opiskelumahdollisuudet. Tutkimuksen viitekehyksen liittyvinä keskeisinä elementteinä olivat tietokoneavusteinen opetus opetusmenetelmänä ja sen valintaan liittyvät tekijät: oppisisällöt ja oppimiselle asetetut tavoitteet, opettajan opetusmenetelmällinen osaaminen, erilaiset oppijat yksilöllisine oppimistavoitteineen sekä käytettävissä olevat erilaiset oppimateriaalit. Tutkimus toteutettiin toimintatutkimuksena ja siihen osallistui tutkijan lisäksi 15 sähköalan opettajaa kahdesta erikokoisesta ammattioppilaitoksesta. Varsinainen toimintatutkimus aloitettiin keväällä 1994 ja se jatkui kevääseen 1996. Lisäksi suoritettiin vertaileva tutkimus, johon osallistui 9 opettajaa kolmesta erillisestä ammattioppilaitoksesta syksyllä 1996 jatkuen kevääseen 1997. Keskeisimmistä tutkimustuloksista mainitsen opettajien heikon tuntemuksen tietokoneavusteisesta opetuksesta ja sen hyödyntämiseen liittyvistä elementeistä. Opettajilta puuttuu taito suunnitella tietokoneavusteisia opetusohjelmia oppimateriaaleina hyödyntäviä opetus- ja oppimistilanteita. Tutkimuksen mukaan opettajilla ei kuitenkaan ole negatiivista ennakkoasennetta opetusmenetelmää kohtaan ja opiskelijat suhtautuvat erittäin myönteisesti erilaisiin tietokoneavusteisiin opetusohjelmiin oppimateriaaleina.

Nuorten kokema yksinäisyys ja sen yhteys tulevaisuusorientaatioon

The aim of this study was to examine 1) how much and how adolescents experience loneliness, 2) how they orientate to the future, 3) are loneliness experiences and future attitudes associated with self-esteem and 4) are loneliness experiences associated with future orientation. The data (n=172) was collected in September 2003 and it consisted of 9th grade students living in countryside and city. The research was quantitative questionnaire study and it was statistically analysed. So far the problem of loneliness has not been noticed enough. People experience loneliness when there is discrepancy between actual and desired levels of interpersonal contact. In adolescence loneliness is quite common because young people go through the crises of human relationships and identity. In adolescence the meaning of friends and fellows increases and the relationship with parents changes. Future orientation becomes meaningful in adolescence because young people have to make realistic choices concerning their future life. In this study almost every adolescent had someone to be with and talk to. However 19% of adolescents experienced loneliness. Lonely adolescents experienced lack of friendships and fellowships. Lonely adolescents also felt that they left outside of others and that they were alone. Boys experienced more often lack of friendships and fellowships than girls. Girls experienced that they left more often outside and that they were more often alone than boys. Adolescents living in city experienced a little more loneliness experiences than adolescents living in countryside. Lonely adolescents had also difficulties to make social relationships and they experienced loneliness also related with parents. Lonely adolescents had also weak self-esteem. Adolescents orientated to the future mainly positively. The most important future target was health and the least important target was the universal peace and problems solving of the world. Adolescents believed that they affect to their future mainly by themselves and they planed their future about 5-10 years ahead. For adolescents it was important to have education and work to the future. In the future it was also important to have a lifelong companion and own family. For most of the young people it was also important to keep up social relationships and realize him/herself. Adolescents thought high standard of living and money also quite important things in the future. Girls preferred different future targets more important than boys. For the boys only money and high standard of living were more important than for girls. 18% of adolescents had pessimistic attitude to the future. For pessimistic adolescents many future targets were less important than for the adolescents having affirmative or optimistic attitude for the future. Adolescents who had pessimistic attitude to the future had also weak self-esteem. For the lonely adolescents it was not so important 1) to keep up social relationships and realize themselves in the future. Lonely adolescents did not prefer 2) lifelong companion and own family as important as other young people. Also 3) others acceptance and appreciation were not so important for lonely adolescents. 4) Travelling was also more insignificant for lonely than for others. Lonely adolescents future attitudes were quite pessimistic. Parent related loneliness explained future targets insignificance and pessimistic attitude for the future the most. The experience of loneliness seems to be associated with future orientation in many cases. That s why it is important to pay attention to adolescents loneliness experiences. Loneliness is real and serious problem which threats health. Thus we need to examine further loneliness in adolescence and as a result of that it is possible to develop and use interventions to help lonely adolescents to orientate positively to their future.

Luova mieli : lähikuvassa muusikoiden luomisprosessit

This work studied the creative process of musicians. The subject was chosen partly due to the attention given to creativity in social discussion. The approach was material-based, because during the work it became clear that the theoretical models describing the creative process in general did not provide adequate tools for the examination of musical creation. In this study, the creative process was defined as a process, which generated a work found by the musician novel to him or her. There were two principal research questions: 1) How does the creative process of musicians progress? 2) What makes a process creative? The main emphasis was on the first question, because the study aimed at modeling the creative process of musicians. The material for this study was collected by interviewing five professional musicians, each qualified by an expert of music to be creative. The interviews were thematically linked with each musician’s recently implemented creative process. The work generated in the process was used as a stimulant in the interview. The main themes of the interview dealt with the musician’s concrete action, cognitive functioning and affective experience during the process. Secondary themes included his or her goals as well as the factors that enhanced or inhibited the process. A material-based analysis was made of the interviews. The conceptualization and modelling of the creative process was founded on a phenomenological-hermeneutic interpretation. In addition to the primary interviews, also supplementary interviews were made in order to ensure that the description of the musician was understood correctly. Further supplementary interviews were made when the material was analyzed and results were deduced. This aimed at increasing the reliability of interpretations and conclusions. The study resulted in a four-level model representing the progress of a creative process. The levels were defined by means of the conception of state. The levels used in defining the process were 1) the state determining the potential of the process, 2) the state delimiting the process, 3) the state orienting the process, and 4) the state determined by the process. The progress of the process was described as changes taking place in the state. It was discovered that the factors having an effect on the creativity of the process were the dynamism of the process, the musician’s work in relation to his or her inner standard and the impulses that caused variation in the musician’s thinking. The interview method used in this study proved to be a very suitable tool in an examination of a creative process. Thus it may well be applicable in other research contexts associated with creative processes. The outcome of this study, the model of the progress of a creative process, should also provide a feasible basis for the examination of different kinds of creative processes. It enables a comprehensive examination of a creative process, simultaneously justifying the dynamic nature of the process.

Mikä yliopisto-opiskelijaa kiihdyttää? : Opiskeluympäristöjen tutkimusta CASS-kokemusotantamenetelmällä flow-teoriaa ja ydintunneteorioita soveltaen

Flow experience is often defined either as an experience of high concentration and enjoyment or as a situation, where high challenges are matched with high skills. According to core-emotion theories, the experience of any emotion contains two core emotions: valence and arousal. Through an accurate mathematical model, the present study investigated, whether the experience of concentration and enjoyment is related to situations where both challenge and skills are high and in balance. Further, it was investigated what sort of core emotions are related to differing relationships between challenge and skills. Finally, university students’ experiences of their natural study environments were described in terms of core emotions and in terms of relationships between challenge and skills. Participants were 55 university students who participated two weeks research period. Altogether 3367 questionnaire answers were collected with the CASS experience-sampling method, operating in 3G-mobile phones. The relationship between challenge and skills (competence) was defined in an exact way in polar coordinates. An enjoyable and concentrated flow experience was defined as a sum variable of absorption, interest and enthusiasm. Core emotions were calculated with factor analysis from nine emotion variables. As expected, an experience of concentration and enjoyment was, on average, related to the situations where both challenge and skills were high and in balance. This was not, however, the case in every situation. Thus, it should be taken into consideration how flow experience is operationalised in experience sampling studies. When flow experience was defined as a situation of high challenge and high skills, it was often related to high valence and arousal emotions such as excitement or enthusiasm. A happier or a more tranquil enjoyment was related to situations of moderate challenge and high skills. Experiences differed clearly between various natural study environments. At lectures students were often bored or mentally absent, and did not experience challenges. In a small group students were often excited or enthusiastic, and showed optimal balance between challenge and skills. At library students felt satisfied and were engaged in highly challenging work.

Integrated semantic processing of complex pictures and spoken sentences - Evidence from event-related potentials

It has been suggested that semantic information processing is modularized according to the input form (e.g., visual, verbal, non-verbal sound). A great deal of research has concentrated on detecting a separate verbal module. Also, it has traditionally been assumed in linguistics that the meaning of a single clause is computed before integration to a wider context. Recent research has called these views into question. The present study explored whether it is reasonable to assume separate verbal and nonverbal semantic systems in the light of the evidence from event-related potentials (ERPs). The study also provided information on whether the context influences processing of a single clause before the local meaning is computed. The focus was on an ERP called N400. Its amplitude is assumed to reflect the effort required to integrate an item to the preceding context. For instance, if a word is anomalous in its context, it will elicit a larger N400. N400 has been observed in experiments using both verbal and nonverbal stimuli. Contents of a single sentence were not hypothesized to influence the N400 amplitude. Only the combined contents of the sentence and the picture were hypothesized to influence the N400. The subjects (n = 17) viewed pictures on a computer screen while hearing sentences through headphones. Their task was to judge the congruency of the picture and the sentence. There were four conditions: 1) the picture and the sentence were congruent and sensible, 2) the sentence and the picture were congruent, but the sentence ended anomalously, 3) the picture and the sentence were incongruent but sensible, 4) the picture and the sentence were incongruent and anomalous. Stimuli from the four conditions were presented in a semi-randomized sequence. Their electroencephalography was simultaneously recorded. ERPs were computed for the four conditions. The amplitude of the N400 effect was largest in the incongruent sentence-picture -pairs. The anomalously ending sentences did not elicit a larger N400 than the sensible sentences. The results suggest that there is no separate verbal semantic system, and that the meaning of a single clause is not processed independent of the context.

Lasten vaikeiden ja stressaavien tilanteiden hallinta yläkouluun siirtymisen vaiheessa

This study examined year seven students´ proactive coping, self-efficacy and social support seeking. Proactive coping was defined as a behaviour where obstacles are seen as a challenge. In proactive coping, individuals set goals, build up resources and regulate their behaviour to achieve the goals. Self-efficacy can be seen as people’s beliefs about their capabilities. Social support seeking was divided into instrumental support seeking and emotional support seeking. According to the theoretical frame of this study self-efficacy and social support seeking were seen as resources to proactive coping (Greenglass 2002). The participants were 445 year seven students (Mo= 13 years) from seven secondary schools. The data was collected in March-May 2008. The survey consisted 37 Likert-scaled items from the Proactive Coping Inventory and from the General Self-Efficacy Scale. The survey consisted of four scales: Proactive Coping, Instrumental Support Seeking, Emotional Support Seeking and General Self-Efficacy. The participants' age, gender and studying in specialist streams were asked as background information. As a result, most of the participants (62 % girls, 38 % boys) reported fairly strong proactive coping: they can see obstacles as a challenge and they set goals and regulate their behaviour to achieve the goals. Most of the participants reported that they seek instrumental and emotional support when having troubles. Girls reported more social support seeking than did boys and the mean difference was statistically significant. Most of the participants had fairly high sense of self-efficacy. However, 4 % of the participants reported that they don’t believe in their capabilities. Some of these participants reported that they neither use proactive coping nor seek informational or emotional support when having troubles. Proactive coping correlated positively with self-efficacy and with social support seeking. In this study self-efficacy and social support seeking explained 47 % of proactive coping. It was discussed that children’s high sense of self-efficacy and social relationships can act as protective factors in transition to secondary school. When supporting children’s self-efficacy and social relationships one also assists children’s proactive coping. Proactive coping can be seen to support children’s personal growth.

Hiljainen tieto henkilöstön valinnassa : tutkimus työhaastatteluiden arvioinnissa hyödynnettävän tiedon hiljaisesta ulottuvuudesta

This study examined the fundamental question of what really matters when selecting a new employee. The study focused on tacit knowledge used by personnel recruiters when interviewing employees. Knowledge was defined as the best view available, which helps one not to act haphazardly. Tacit knowledge was also defined as a positive concept, and it was seen as a part of personnel recruiters` improving proficiency. The research topic was chosen based on the observed increase in the amount of employment interviews and their importance in society. As recruiting is becoming a more distinct profession, it was reasonable to approach the topic from an educational point of view. The following research problems guided the examination of the phenomenon: 1) Where does the interviewer seek tacit knowledge from during the employment interview? 2) How is tacit knowledge achieved during the employment interview? 3) How does the interviewer defend the significance of the tacit knowledge gained as knowledge that has influence on the selection decision? The research data was collected by interviewing six personnel recruiters who conduct and evaluate employment interviews as part of their work responsibilities. The interview themes were linked to some recently made selection decision in each organization and the preceding employment interview with the selected candidate. In order to conceptualize tacit knowledge, reflective consideration of the interview event was used in the study. The lettered research data was analyzed inductively. As a result of the study, the objects of tacit knowledge in the context of an employment interview culminated into three areas: the applicant s verbal communication, the applicant s non-verbal communication and the interaction between interview participants. Observations directed toward those objects were shown to be intentional and three schemes were found behind them: experiences from previous interviews, applicant s application papers and the aptitude for the work responsibilities. The question of gaining knowledge was answered with the concept of procedural knowledge. Personnel recruiters were found to have four different, but interconnected ways to encounter knowledge during an employment interview: understanding, evaluative, revealing, and approving knowing. In order to explain the importance given to tacit knowledge, it was examined in connection with the most prevalent practices in the personnel selection industry. The significance of knowledge as the kind of knowledge that has an impact on the decision was supported by references to collective opinion (other people agree with it), circumstance (interview s short duration), or using some instrument (structured interview). The study revealed new aspects of employment selection process through examining tacit knowledge. The characteristics of the inductive analysis of the research data may also be utilized, when applicable, in tacit knowledge research within other contexts.

Ryhmäidentiteetin mittaaminen verkkoroolipelissä World of Warcraft

The objective of the study was to explore the dimensions of group identity in the guilds of World of Warcraft. Previous research shows that social interaction has an important role in playing games for many players. Social identities are an important aspect of self-concept and since group related cues are more salient than personal clues in computer-mediated communication, the social gaming experience was approached through group identity. In the study a new scale will be developed to measure the group identity in games. Secondary goal is to study how different guild attributes affect the group identity and third goal is to explore the connection between group identity and gaming experience and amount of play. Subjects were 1203 guild members and 106 players not in a guild. The data was gathered by an Internet survey which measured group identity with nine scales, gaming experience with three scales and guild attributes with four scales. Also various background data was gathered. The construct of group identity was analyzed with explorative factor analysis. The typical experiences of group identity was analyzed with cluster analysis and effects of guild attributes with multivariate analysis of covariance. As a result of the study a new scale was developed which measured group identity on six dimensions: self-stereotyping, public and private evaluation, importance, interconnection of self and others and awareness of content. Group identity was experienced strongest in elder middle-sized guilds that had formal rules and that emphasized social interaction. The players with strong group identity had more positive gaming experience and played World of Warcraft more per week than the players who were not in a guild or identified to guild weakly. This result encourages game developers to produce environments that enhance group identity as it seems to increase the enjoyment in games. As a whole this study proposes that group identity in guilds is constructed from the same elements as in traditional groups. If this is truly the case, guild membership may have similar positive effects on individual’s mental well-being as traditional positively evaluated group memberships have.

Jaksaako opettaja kehittyä? : Ammatillisen kehityksen ja täydennyskoulutuksen merkitys opettajien työssä jaksamisessa

The aim of this study was to investigate the connection between teachers' burn-out and professional development. In addition, the study aimed at clarifying teachers' conceptions of the significance of in-service training on work-related well-being. The theoretical starting points of the study were based on a model of burn-out (Kalimo & Toppinen1997) and a model of teachers' professional development (Niemi 1989). Present study can be seen as an independent follow-up study for a working ability project called "Uudistumisen eväät" that was followed through in Kuopio. The study was carried out in two phases. First, the connection between teachers' burn-out and professional development was charted with the help of a quantitative survey study. 131 teachers participated in the survey. Some of them were from schools that participated in the working ability project and the remainder were from other schools in Kuopio. The questionnaire consisted of self-constructed instruments of burn-out and professional development. According to the results, burn-out and professional development were strongly correlated with each other. Burn-out was summed up in three factors: emotional exhaustion, feelings of depersonalization and low feelings of personal accomplishment. Professional development was summed up in four factors: personality and pedagogical skills, learning-orientation, social skills and confronting change. Personality and pedagogical skills and skills of confronting change were correlated strongest with burn-out and its symptoms. A teacher, who has not found his/her own personal way of acting as a teacher and who considers change as something negative, is more likely to become exhausted than a teacher, who has developed his/her own pedagogical identity and who regards change more positively. In the second phase of this study, teachers' conceptions of the significance of in-service training on well-being was investigated with the help of group interviews (n=12). According to the results, the importance of in-service training was significant on the well-being of teachers. It appeared that in-service training promotes well-being by providing teachers with motivation, professional development and the possibility of taking a break from teaching and cooperating with other teachers. It has to be based on teachers' own needs. It has to be offered to teachers frequently and early enough. If teachers are already exhausted, they will neither have enough resources to participate in training, nor will they have the strength to make good use of it in practice. Both professional development and well-being are becoming more and more essential now that society is changing rapidly and the demands set on teachers are growing. Professional development can promote well-being, but are teachers too exhausted to develop themselves? Professional development demands resources and teachers may regard it as a threat and an additional strain. When the demands are so high that teachers cannot cope with them, they are likely to suffer stress and see reduction of commitment to their work and its development as a means to survive. If teachers stop caring about their work and their own development, how can we expect them to promote pupils' learning and development? It should be considered in the planning and implementation of in-service training and in arranging teachers' working conditions, that teachers have enough time and resources to develop themselves.

Sosiaalisen verkostoanalyysin soveltuminen yhteisöllisen verkko-oppimisen tutkimiseen

Tietotekniikan kehittyessä lisääntyy sekä tietotyön tekijöiden tarve että paine tehostaa opetusta tietotekniikan avulla. Tietotyöläisten tarvitsemien taitojen opettamiseen tarvitaan uutta pedagogiikkaa, jossa korostetaan tietojen ja sääntöjen seuraamisen sijaan taitoja, itsenäisyyttä ja oppimaan oppimista. Tietotekniikankäyttäminen opetuksessa tuo omat haasteensa oppimistilanteisiin. Sosiokonstruktiivinen, yhteisöllinenverkko"-oppiminen onkin nousemassa perinteisen opettajajohtoisen opetuksen haastajaksi. Suomessa kehitetty Tutkiva oppiminen on yksi tämän viitekehyksen mukaisista pedagogisista menetelmistä. Koska sosiokonstruktiivinen teoria korostaa ihmisten välisiä suhteita yli yksittäisen ihmisen toiminnan, alan tutkimuksenkin on otettava kantaa tutkimustilanteessa esiintyviin vuorovaikutussuhteisiin. Tähän perinteiset psykologiset ja pedagogiset menetelmät eivät sovellu, kun taas sosiaalitieteissä suhteellisen vanha analyysimenetelmä, SVA eli sosiaalinen verkostoanalyysi, on tarkoitettu nimen\-omaan ihmisryhmien analysoimiseen. SVA:n sovellukset psykologian ja yhteisöllisen oppimisen alueilla ovat kuitenkin vasta alustavia, eikä luotettavaa näyttöä menetelmän soveltumisesta saatika hyödyllisistä tuloksista vielä ole. Tämän tutkimuksen on tarkoitus selvittää, onko SVA sovellettavissa tälle tutkimuksen alueelle. Tässä tutkimuksessa SVA:ta käytettiin 23 peruskoulu- ja lukioluokan Tutkivan oppimisen menetelmällä toteutettujen oppimistilanteiden tutkimiseen. Tulokset osoittavat, että SVA soveltuu yhteisöllisen verkko-oppimisen tutkimiseen, sillä tästä aineistosta löytyi alustavia SVA:n tunnuslukuja, jotka ovat yhteydessä oppimistilanteen laatuun. Tulokset ovat myös pitkälti sosiokonstruktiivisen teorian mukaisia: kurssin hyöty nousee, kun useat oppilaat kirjoittavat korkealaatuisia viestejä ja osallistuvat kattavasti eri keskusteluihin. Avainsanat: Tutkiva oppiminen, sosiokonstruktivismi, pedagogiikka, yhteisöllisyys, yhteisöllinen verkko-oppiminen, Fle3, SVA, sosiaalinen verkostoanalyysi, koulu, opetus.

Mielialan havainnoinnin, tunnistamisen ja säätelyn yhteydet työuupumuksen ryhmähoidon tuloksellisuuteen.

Työuupumus on kolmitahoinen stressioireyhtymä, jolle on tyypillistä uupumusasteinen väsymys, kyynistyneisyys ja ammatillisen itsetunnon heikkeneminen. Balanssi-hanke perustettiin tutkimaan ja kehittämään ryhmähoitomuotoa vakavaan työuupumukseen. Projektin tavoitteena on selvittää kahden eri ryhmähoitomuodon vaikuttavuutta ja sellaisia yksilöön liittyviä tekijöitä, joilla saattaa olla vaikutusta ryhmähoidon tuloksellisuuteen. Tässä tutkimuksessa selvitettiin mielialan havainnoinnin, tunnistamisen ja säätelyn (Trait Meta-Mood) yhteyksiä työuupumuksen laskuun ryhmähoitojen aikana ja kuuden kuukauden pituisella seurantajaksolla. Emootioilla on useiden eri teorioiden mukaan yksilön sopeutumista edistävä signaalitehtävä. Mieliala kertoo yksilön sisäisestä tilasta, ja sitä voidaan kuvata miellyttävänä, epämiellyttävänä, kiihtyneenä tai rauhallisena. Mielialaa voi tarkastella mielialakokemuksen tai mielialan säätelyn tasolla. Mielialan säätelyn tasolla tarkoitetaan ajatuksia mielialasta. Tällä reflektiivisellä tasolla mielialaa havainnoidaan, tunnistetaan ja säädellään. Oletettiin, että jos mieliala tunnistetaan hyvin ja mielialaa säädellään tehokkaasti, työuupumus vähenee eli työuupumuksen ryhmähoito on tuloksellista. Lisäksi tutkittiin missä vaiheessa mahdolliset yhteydet ilmenevät ja eroavatko yhteydet psykoanalyyttisessä ja toiminnallisessa hoitoryhmässä. Tutkimusaineisto kerättiin 1999-2000. Koehenkilöt (n=99) olivat 31-59-vuotiaita valtion laitosten ja valtion yritysten työuupumuksesta kärsiviä työntekijöitä, miehiä oli 24 ja naisia 75. Lisäksi kerättiin ei-uupuneiden kontrolliryhmä (n = 26, ikä 37 - 58 vuotta), jota hyödynnettiin tässä tutkimuksessa vain uupuneiden ja ei-uupuneiden vertailuihin ennen hoidon alkua. Molempina vuosina uupuneet henkilöt satunnaistettiin toiminnallisiin ja psykoanalyyttisiin hoitoryhmiin. Työuupumus mitattiin 9 kuukautta kestäneen hoidon alussa, lopussa ja puoli vuotta hoidon päättymisen jälkeen. Mielialan havainnointi, tunnistaminen ja säätely mitattiin hoidon alussa, lopussa ja puoli vuotta hoidon päättymisen jälkeen. Tulokset osoittivat, että mielialan tunnistamisen korkea taso ja mielialan säätelyn korkea taso olivat yhteydessä työuupumuksen voimakkaampaan laskuun koko tutkimusjakson ajan. Yhteydet olivat erilaiset eri ryhmähoidoissa hoidon aikana ja seurantajaksolla. Hoidon aikana psykoanalyyttisessä hoitoryhmässä mielialan havainnoinnin lisääntyminen ja mielialan säätelyn tehokkuus olivat yhteydessä työuupumuksen voimakkaampaan laskuun. Toiminnallisessa hoitoryhmässä sen sijaan mielialan tunnistamisen taito oli yhteydessä työuupumuksen voimakkaampaan laskuun hoidon aikana. Seurantajaksolla molemmissa hoitoryhmissä mielialan tunnistamisen taito oli yhteydessä työuupumuksen voimakkaampaan laskuun. Kontrolliryhmässä ei todettu mielialan havainnoinnin, tunnistamisen ja säätelyn taitojen ja työuupumuksen vähenemisen välistä yhteyttä. Tutkimuksen tulokset antavat uutta tietoa sellaisista yksilöllisistä tekijöistä, joilla on työuupumuksen ryhmähoitoprosessia moderoiva rooli. Mielialan hyvin tunnistaminen ja mielialan tehokas säätely saattavat olla sellaisia ryhmäterapiassa opittuja yksilöllisiä voimavaroja, joita työuupumuksesta toipumisessa tarvitaan hoidon päättymisen jälkeen. Koska mielialan hyvin tunnistamisen, mielialan tehokkaan säätelyn ja työuupumuksen ryhmähoidon tuloksellisuuden väliset yhteydet todettiin molemmissa ryhmähoitomenetelmissä, voi olettaa, että molemmat ryhmähoitomenetelmät ovat vakavaa työuupumusta vähentäviä hoitomenetelmiä. Ryhmähoidon aikana opitut mielialan tunnistamisen ja säätelyn taidot auttavat ylläpitämään terapian aikana alkanutta hyvinvoinnin kasvua. Avainsanat: työuupumus, toiminnallinen ryhmäterapia, psykoanalyyttinen ryhmäterapia, mielialan havainnointi, mielialan tunnistaminen, mielialan säätely, työuupumuksen ryhmähoidon tuloksellisuus

Tarinakontekstin vaikutus sanojen muistamiseen kompleksisessa työmuistitehtävässä

Objectives. The sentence span task is a complex working memory span task used for estimating total working memory capacity for both processing (sentence comprehension) and storage (remembering a set of words). Several traditional models of working memory suggest that performance on these tasks relies on phonological short-term storage. However, long-term memory effects as well as the effects of expertise and strategies have challenged this view. This study uses a working memory task that aids the creation of retrieval structures in the form of stories, which have been shown to form integrated structures in longterm memory. The research question is whether sentence and story contexts boost memory performance in a complex working memory task. The hypothesis is that storage of the words in the task takes place in long-term memory. Evidence of this would be better recall for words as parts of sentences than for separate words, and, particularly, a beneficial effect for words as part of an organized story. Methods. Twenty stories consisting of five sentences each were constructed, and the stimuli in all experimental conditions were based on these sentences and sentence-final words, reordered and recombined for the other conditions. Participants read aloud sets of five sentences that either formed a story or not. In one condition they had to report all the last words at the end of the set, in another, they memorised an additional separate word with each sentence. The sentences were presented on the screen one word at a time (500 ms). After the presentation of each sentence, the participant verified a statement about the sentence. After five sentences, the participant repeated back the words in correct positions. Experiment 1 (n=16) used immediate recall, experiment 2 (n=21) both immediate recall and recall after a distraction interval (the operation span task). In experiment 2 a distracting mental arithmetic task was presented instead of recall in half of the trials, and an individual word was added before each sentence in the two experimental conditions when the participants were to memorize the sentence final words. Subjects also performed a listening span task (in exp.1) or an operation span task (exp.2) to allow comparison of the estimated span and performance in the story task. Results were analysed using correlations, repeated measures ANOVA and a chi-square goodness of fit test on the distribution of errors. Results and discussion. Both the relatedness of the sentences (the story condition) and the inclusion of the words into sentences helped memory. An interaction showed that the story condition had a greater effect on last words than separate words. The beneficial effect of the story was shown in all serial positions. The effects remained in delayed recall. When the sentences formed stories, performance in verification of the statements about sentence context was better. This, as well as the differing distributions of errors in different experimental conditions, suggest different levels of representation are in use in the different conditions. In the story condition, the nature of these representations could be in the form of an organized memory structure, a situation model. The other working memory tasks had only few week correlations to the story task. This could indicate that different processes are in use in the tasks. The results do not support short-term phonological storage, but instead are compatible with the words being encoded to LTM during the task.

Tiedonhakustrategiat World Wide Webissä

Tutkimuksen tarkoituksena on selvittää, millaisia tiedonhakustrategioita tiedonhakijatkäyttävät etsiessään tietoa Internetistä. Käyttäjät luokitellaan kolmeen ryhmään tiedonhakustrategiansa mukaan. Haku-suuntautuneet käyttäjät käyttävät enimmäkseen hakukoneita, niin koko Internetin kattavia kuin sivustojen sisäisiäkin. Linkkisuuntautuneet taas joko tietävät tai arvaavat kohdesivuston osoitteen tai käyttävät laajoja hierarkkisia hakemistoja tiedon löytämiseen. He navigoivat mielummin sivustollakin linkkejä käyttäen eivätkä yleensä käytä hakutoimintoa. Eriytyneet käyttäjät eivät säännönmukaisesti suosi kumpaakaan tapaa, vaan valitsevat strategian tehtävän mukaan. Tietoa kerättiin kahdella tavalla: WWW-sivulla olleella kyselylomakkeella ja tiedonhakutestillä, jossa käyttäjille annettiin suoritettavaksi erilaisia tiedonhakutehtäviä. Tiedonhakutehtävät lajiteltiin kolmeen ryhmään sen mukaan, mitä strategiaa ne suosivat: hakustrategiaa suosivat, linkkistrategiaa suosivat ja neutraalit tehtävät. Tutkimusongelmana oli selvittää, kuinka tehtävän tyyppi ja ATK- ja Internet-kokemus vaikuttavat tiedonhakustrategian valintaan. Kävi ilmi, ettei käyttäjien suuntautuneisuus tiettyyn strategiaan vaikuta tiedonhakustrategian valintaan, vaan ainoastaan tehtävän tyyppi oli merkitsevä tekijä. Aikaisemman tutkimustiedon valossa kokeenet suosivat haku-suuntautunutta strategiaa. Tässä tutkimuksessa havaittiin, että kokemus lisäsi molempien strategioiden käyttöä yhtäläisesti, mutta tämä ilmiö oli havaittavissa ainoastaan kysely-lomakkeen pohjalta, ei testeissä. Molempien tiedonhakustrategioiden käyttö lisääntyy kokemuksen myötä, mutta suhteelliset osuudet pysyvät samoina. Syyksi sille, että kokeneet eivät suosineet hakustrategiaa, esitetään sitä, että tehtävät olivat liian helppoja, jolloin kokemus ei pääse auttamaan. Oleellisia eroja suoritusajoissa tai hakustrategian vaihdon tiheydessä ei havaittu suhteessa kokemukseen, ainoastaan suhteessa tehtävän tyyppiin.Tämäkin selitettiin toisentyyppisten tehtävien helppoudella. Tutkimuksessa pohditaan lisäksi asiantuntijuuden syntyä tiedonhakukontekstissa sekä esitetään metatietohypoteesi, jonka mukaan tiedonhakustrategian valintaan vaikuttaa tärkeänä tekijänä käyttäjän metatieto hakupalveluista. Metatietoon kuuluu tieto siitä, mitä hakukoneita on saatavilla, mitä tietoa verkosta kannattaa hakea, millä yrityksillä ja yhteisöillä on sisältörikkaat sivut jne, ja minkä tyyppistä tietoa yleensä on saatavilla. Kaikenkaikkiaan strategian valintaan esitetään taustalle kolmen tason tiedon vaikutusta: 1) oma asiantuntemus haettavasta alasta, 2) metatieto Internetin tiedonhakupalveluista sekä 3) tekninen tieto siitä, kuinka hakukoneet toimivat.

Sovelletun rentoutuksen vaikutus psyykkiseen työhyvinvointiin ja sykevaihteluun

Research reveals that more than every fourth Finn experiences work-related exhaustion to some degree. Stress and exhaustion have psychological and physical expressions. The main physical factor in stress is the overloading of the autonomic nervous system, which can be measured for instance by variations of heart rate. Studies show that the work field, management and authority of the work, skill developmental possibilities, and social support inhibit stress overload. The practising of self-relaxation techniques possible inhibits working stress and exhaustion. In this study of preventive rehabilitation, the focus was on the effects of the training of applied relaxation on psychological and physiological variables of stress and empowerment of resources. Participants (n=73) were basically healthy and capable of working, 25-40 of age, workers from the field of mental work. They practised applied relaxation under group conduction for seven weeks. The aim was to learn to relax easily even in everyday occasions. The subjects were tested thirdly. After the first measurement, they were grouped into two groups, of which the first group started the relaxation training. The second group began practising half a year after the second measurement. The third measurement was done one year after the beginning of the study. It was hypothesised that the training of applied relaxation would significantly reduce stress on both psychological and physiological variables and that these variables would correlate positively. Results revealed that the training of applied relaxation reduced psychological stress symptoms rather modestly. The changes were more significant in women, who experienced a slight increase in self-directivity. Physical changes were slight decreases of the sympathetic activation. The correlations of psychological and physiological variables were modest. Some changes were reduced after the active training. There was a positive interrelation between experienced work-related demands of efficiency, insufficient social support and exhaustion. There was a tendency to significance between skill developmental possibilities and psychological stress symptoms. Further implications of the results were discussed.

Muslimioppilas suomalaisessa peruskoulussa : Tapaustutkimus kahden muslimitytön sopeutumisesta suomalaiseen peruskouluun

Tutkielma on etnografisella tutkimusotteella toteutettu tapaustutkimus, jossa oli tutkimuskohteena yksi pääkaupunkiseudun peruskoulun neljäs luokka. Tutkimus suoritettiin kevätlukukaudella 1998. Luokalla oli 24 oppilasta, joista kaksi oli somalialaisia muslimityttöjä. Aineistonkeruumenetelmiä olivat osallistuva havainnointi, teemahaastattelut, keskustelut ja luokan oppilaiden kirjoittamat kirjoitelmat. Tutkimustehtävänä oli kuvata ja ymmärtää muslimityttöjen olemassaolon vaikutusta luokan arkipäivään luokan eri osapuolien kannalta. Kiinnostuksen kohteena oli, miten opettaja ja luokan muut oppilaat suhtautuivat muslimityttöihin ja millaisia olivat muslimityttöjen omat kokemukset luokan elämästä ja miten heidän uskontonsa, islam, näkyi koulupäivän aikana. Tutkimustuloksista: Islam näkyi koulupäivän aikana konkreettisimmin muslimityttöjen pukeutumisessa ja ruokailussa. He saivat myös islaminuskon opetusta, harjoittelivat paastoamista paastokuukauden aikana ja heillä oli lupa olla pois koulusta muslimien juhlapyhinä. Luokan muut oppilaat tiesivät, että muslimitytöillä oli eri uskonto kuin heillä, mutta he eivät uskoneet sen vaikuttavan muslimityttöjen koulupäivään kovinkaan paljon. Muslimitytöt olivat solmineet ystävyyssuhteita luokan suomalaisiin tyttöihin ja he viihtyivät hyvin heidän kanssaan. Muslimityttöjä oli kuitenkin kiusattu enemmän kuin luokan muita oppilaita, mutta kiusaaminen oli vähentynyt ajan kuluessa. Muutamilla luokan pojilla oli halveksiva tai vihamielinen suhtautuminen muslimityttöihin. Muslimityttöjen koulunkäyntiin liittyi joitakin vaikeuksia, kuten oppimisvaikeudet muutamissa aineissa ja vaikeudet sopeutua tiettyihin koulun sääntöihin. Luokanopettaja koki yhteistyön muslimityttöjen vanhempien kanssa vaikeaksi. Näistä ongelmista huolimatta muslimitytöillä oli myönteinen suhtautuminen koulunkäyntiin. Tässä tapauksessa muslimitytöt olivat saavuttaneet integraatio-vaiheen Berryn akkulturaatio teorian mukaan. Sopeutuminen peruskoululuokkaan oli onnistunut heiltä hyvin lähinnä luokanopettajan toiminnan johdosta. He puhuivat hyvin suomen kieltä ja olivat asuneet Suomessa jo usean vuoden ajan, mikä myös helpotti sopeutumista.
