Ethical problems occurring during the practical training period of Finnish nursing students The present study focused on nursing students adopting the professional code of conduct during their supervised practical training. The study was carried out in two phases. During the first phase, the objective was to survey ethical problems occurring in practical training as well as how these problems are detected and resolved by nursing students and their supervisors at different stages of their studies. In the second phase, the capability of the nursing students about to graduate to detect and resolve ethical problems was described and analyzed. The students’ capacity for self-instruction, independent search for information as well as factors related to teaching of ethics were determined within this phase. Further, an extensive literature review was carried out to complement the study. Thus, the main objective of the thesis was to make suggestions for the development of the teaching of ethics and supervision in nursing studies and in practice. In the first part of the empirical phase (2002–2005), the views of the nursing students (n =18) were clarified with themed open essay questions. Furthermore, the views of the supervising nurses (n = 115) were established by utilizing a series of themed questions and group interviews. During the second phase (2006–2007), the data for the analyses were collected from nursing students in their graduating stage (n = 319) by a national Internet-based questionnaire. The results of the first phase were examined with contentanalysis and those of the second phase both statistically and by using content analysis. Ethical problems occurring during supervised practical training were typically connected to a patient or a client, a member of the nursing staff or to a student, while solutions were connected to preparation and the action to solve the problem in question. Ethical dilemmas were classified as legal, ethical comportment and uncertainty problems as well as personal and institutional ones. The solutions for these problems were further grouped as based on facts, instructor/staff/member/specialist or patient/client/relative. The results showed that although the nursing students about to graduate had detected many ethical problems both independently as well as together with the nursing staff during every practical training period, they were able to resolve only few of them. Ethical problems were most frequently encountered during training in psychiatric nursing. On the grounds of their own impressions, the nursing students stated that their ability to detect and solve ethical problems improved during their training period. The primary factors related to this enhancement of their skills were teaching and the students’ readiness for selfinstruction. Gender, orientation of the studies and age were observed to be the most important among the underlying factors influencing the capability to detect and solve ethical problems as well as to engage in self-instruction. Based on the results obtained, suggestions for development as well as topics for further studies are presented through teaching of professional ethics and supervision during practical training.

The research assesses the skills of upper comprehensive school pupils in history. The focus is on locating personal motives, assessing wider reasons hidden in historical sources and evaluating source reliability. The research also questions how a wide use of multiple sources affects pupils’ holistic understanding of historical phenomena. The participants were a multicultural group of pupils. The origins of their cultures can be traced to the Balkan, the Middle East, Asia and Europe. The number of native Finnish speakers and pupils speaking Finnish as their second language was almost equal. The multicultural composition provides opportunities to assess how culturally responsive learning history from sources is. The intercultural approach to learning in a multicultural setting emphasizes equality as a precondition for learning. In order to set assignments at least to some extent match with all participants only those answers were taken into account which were produced by pupils who had studied history for a similar period of time in the Finnish comprehensive school system. Due to the small number of participants (41), the study avoids wide generalizations. Nevertheless, possible cultural blueprints in pupils’ way of thinking are noted. The first test examined the skills of pupils to find motives for emigration. The results showed that for 7th graders finding reasons is not a problematic task. However, the number of reasons noticed and justifications varied. In addition, the way the pupils explained their choices was a distinguishing factor. Some pupils interpreted source material making use of previous knowledge on the issue, while other pupils based their analysis solely on the text handed and did not try to add their own knowledge. Answers were divided into three categories: historical, explanatory and stating. Historical answers combined smoothly previously learned historical knowledge to one’s own source analysis; explanatory answers often ignored a wider frame, although they were effective when explaining e.g. historical concepts. The stating answers only noticed motives from the sources and made no attempts to explain them historically. Was the first test culturally responsive? All pupils representing different cultures tackled the first source exam successfully, but there were some signs of how historical concepts are understood in a slightly different way if the pupil’s personal history has no linkage to the concepts under scrutiny. The second test focused on the history of Native Americans. The test first required pupils to recognize whether short source extracts (5) were written by Indians or Caucasians. Based on what they had already learned from North American history, the pupils did not find it hard to distinguish between the sources. The analysis of multiphase causes and consequences of the disputes between Native Americans and white Americans caused dispersion among pupils. Using two historical sources and combining historical knowledge from both of them simultaneously was cumbersome for many. The explanations of consequences can be divided into two groups: the ones emphasizing short term consequences and those placing emphasis on long term consequences. The short term approach was mainly followed by boys in every group. The girls mainly paid attention to long term consequences. The result suggests that historical knowledge in sources is at least to some extent read through role and gender lenses. The third test required pupils to explain in their own words how the three sources given differed in their account of living conditions in Nazi Germany, which turned out to be demanding for many pupils. The pupils’ stronghold was rather the assessment of source reliability and accounts why the sources approached the same events differently. All participants wrote critical and justified comments on reliability and aspects that might have affected the content of the sources. The pupils felt that the main reasons that affected source reliability were the authors’ ethnic background, nationality and profession. The assessment showed that pupils were well aware that position in a historical situation has an impact on historical accounts, but in certain cases the victim’s account was seen as a historical truth. The account of events by a historian was chosen most often as the most reliable source, but it was often justified leniently with an indication to professionalism rather than with clear ideas of how historians conduct accounts based on sources. In brief, the last source test demonstrates that pupils have a strong idea that the ethnicity or nationalism determines how people explained events of the past. It is also an implication that pupils understand how historical knowledge is interpretative. The results also imply that history can be analyzed from a neutral perspective. One’s own membership in an ethnical or religious group does not automatically mean that a person’s cultural identity excludes historical explanations if something in them contradicts with his or her identity. The second method of extracting knowledge of pupils’ historical thinking was an essay analysis. The analysis shows that an analytical account of complicated political issues, which often include a great number of complicated political concepts, leads more likely to an inconsistent structure in the written work of pupils. The material also demonstrates that pupils have a strong tendency to take a critical stance when assessing history. Historical empathy in particular is shown if history somehow has a linkage to young people, children or minorities. Some topics can also awake strong feelings, especially among pupils with emigrant background, if there is a linkage between one’s own personal history and that of the school; and occasionally a student’s historical experience or thoughts replaced school history. Using sources during history lessons at school seems to have many advantages. It enhances the reasoning skills of pupils and their skills to assess the nature of historical knowledge. Thus one of the main aims and a great benefit of source work is to encourage pupils to express their own ideas and opinions. To conclude, when assessing the skills of adolescents in history - their work with sources, comments on history, historical knowledge and finally their historical thinking - one should be cautious and avoid cut off score evaluations. One purpose of pursuing history with sources is to encourage pupils to think independently, which is a useful tool for further identity construction. The idea that pupils have the right to conduct their own interpretations of history can be partially understood as part of a wider learning process, justification to study history comes from extrinsic reasons. The intrinsic reason is history itself; in order to understand history one should have a basic understanding of history as a specific domain of knowledge. Using sources does not mean that knowing history is of secondary importance. Only a balance between knowing the contextual history, understanding basic key concepts and working with sources is a solid base to improve pupils’ historical understanding.

Tutkimuksen teoreettinen tarkoitus on kuvailla yleisesti opetussuunnitelmaa opetuksen suunnittelua ja toteutusta toimeenpanevana työvälineenä. Lisäksi tutkimuksen teoreettinen tarkoitus on kuvailla suomalaista opetussuunnitelmaa historiallisen tarkastelun avulla ja käsityön teknisen työn kaltaisen oppiaineen opetussuunnitelmallista kehitystä. Tutkimuksen empiirinen tarkoitus on löytää käsityön teknisen työn sisältöjen opetuksen suunnittelua ja toteutusta ohjaavat tekijät sekä kuvailla käsityön opetussuunnitelmaa teknisen työn sisältöjen opettajan työvälineenä. Tutkimus kohdistui Suomessa toimiviin peruskoulun yläluokkien (7-9 lk.) käsityön teknisen työn sisältöjen opettajiin. Perusjoukkoon kuului 770 käsityön teknisen työn sisältöjen opettajaa. Perusjoukosta muodostettiin klusteriotannalla koko valtakuntaa edustava ja maantieteelliseen väkilukuun suhteutettu otos, johon valittiin 100 käsityön teknisen työn sisältöjen opettajaa. Tutkimusaineistoon saatiin vastaukset sadalta käsityön teknisen työn sisältöjen opettajalta. Tutkimuksen teoriaosa perustuu opetussuunnitelmaan liittyvien tekijöiden, kuten kirjoitetun opetussuunnitelman, oppimiskäsityksen ja opetuksen suunnitteluprosessin teoreettiseen kuvaukseen. Tutkimuksen empiirinen osa edustaa määrällistä eli kvantitatiivista tutkimusotetta, jossa mittaus suoritettiin yhden kerran tutkimukseen valituille henkilöille. Tutkimuksessa käytetty kyselylomake eli mittari sisälsi 100 Likert -asteikollista väittämää, jotka oli ankkuroitu viisiportaisesti välille ”täysin eri mieltä” – ”täysin samaa mieltä”. Tutkimustulosten perusteella käsityön opetussuunnitelman ohjausvaikutus on vähäinen eikä käsityön teknisen työn sisältöjen opettaja ole sitoutunut käyttämään käsityön opetussuunnitelmaa. Käsityön teknisen työn sisältöjen opetuksen suunnittelua ja toteutusta ohjaa oppimisympäristö- ja oppilaskeskeinen Curriculum -ajattelu, jossa opetussuunnitelma toimii vapaana ja löyhänä ohjeena toteutettavaa opetusta varten. Tähän perustuen käsityön teknisen työn sisältöjen opettaja toteuttaa opetustaan voimakkaasti omatoimiseen oppimiseen perustuvien oppilaslähtöisten työtapojen suunnassa. Tulevaisuudessa käsityön teknisen työn sisältöjen opettajien täydennyskoulutukseen pitäisi kiinnittää enemmän huomiota, koska sillä on yhteyttä siihen, missä määrin he käyttävät käsityön opetussuunnitelmaa oman opetuksen suunnittelu- ja toteutusprosessissa.

Oikein suoritettu suorituskyvyn mittaaminen tuo kirjallisuuden mukaan organisaatiolle monia hyötyjä. Julkisen sektorin toimijat kohtaavat kuitenkin useita haasteita suorituskyvyn mittaamisessa ja mittausjärjestelmän suunnittelussa, eikä useimmilla sektorin organisaatioilla ole käytössään kattavaa mittausjärjestelmää. Tämän tutkimuksen tavoitteena oli suunnitella suorituskyvyn mallimittaristo kuntien ja julkisen sektorin sosiaali- ja perusterveydenhuoltotoimialan organisaatioiden käyttöön. Tutkimus toteutettiin case-tutkimuksena konstruktiivista tutkimusotetta käyttäen, sillä työssä pyrittiin kehittämään mallimittaristo, joka on sovellettavissa useaan tapaukseen. Mallimittariston kehittäminen perustui julkisen sektorin sekä sosiaali- ja terveystoimen suorituskykyä ja sen mittaamista käsittelevään tieteelliseen kirjallisuuteen, tutkimukseen ja asiantuntijoiden haastatteluihin. Tutkimuksessa havaittiin, että mittariston suunnitteluprosessissa tulee kiinnittää huomiota erityisesti terminologiaan, mittaamisen tarkoitukseen, nykyiseen mittaamisen tasoon, laatutekijöihin ja vaikutuksiin sekä suorituskyvyn kaikkien osa-alueiden huomioimiseen ja linjassa pitämiseen. Tutkimustuloksena saatiin lisäksi tietoa mittariston rakentamis-prosessista ja tärkeistä mittauskohteista sosiaali- ja perusterveydenhuoltotoimialalla. Jo itse suunnitteluprosessi koettiin hyödylliseksi suorituskyvyn kentän ja sen mittaamisen ymmärtämiseksi. Maakunnan alueellinen kehittäjä hyväksyi mallimittariston ja esitti työn tulokset ja suositukset alueen kunnille. Mittariston toimivuus käytännössä tullaan havaitsemaan siis vasta myöhemmin, mikäli kunnat päättävät ottaa mittariston käyttöön.
