Nuorten koherenssin tunne: mittaaminen, ennustavat tekijät, seuraukset

Sense of coherence in adolescence: measuring, predictive factors, consequences The aim of this study was to explore the stability of sense of coherence (SOC) in adolescence and the associations between childhood psychological symptoms and SOC in adolescence. Furthermore, the aim of this study was to explore whether the 13-item SOC scale for adults is applicable to adolescents 12 years of age and to determine which factors are associated with perceived health and SOC. Data relating to SOC and factors associated with perceived health and SOC were collected in class in a cross-sectional setting by self-administered questionnaires in all publicly funded elementary schools (N=35) of Turku. A total of 1 231 (83%) of 1 481 12-year-old schoolchildren participated in the study. The data was, with appropriated authority consent, anonymously completed with marks in mathematics, native and first foreign language at the end of sixth class. The examination of stability of SOC in adolescence and the associations between childhood psychological symptoms and SOC was based on data of a prospective population-based mail survey. The source population originated in 11 health authority areas of the Province of Turku and Pori. The study was carried out by using questionnaires at child’s ages of 3, 12, 15, and 18 years. Acceptably completed questionnaires were returned by 1 086 (84%) parents at the child’s age of 3, at the age of 12 by 70% adolescents and parents, at the age of 15, by 66% adolescents and 58% parents, and at the age of 18, by 61.5% adolescents and 61% parents. The results of the study showed that childhood behavioural problems from the age of 3 years predicted poor SOC at the age of 18 years. A poor SOC was associated with psychological symptoms and behavioural problems in adolescence. Contrary to assumptions in Antonovsky’s theory, there was no significant change in SOC between the ages of 15 to 18 years, and the stability of SOC did not depend on initial SOC. Slight fluctuation in SOC scores was seen at the individual level. When studied cross-sectionally, in 12-year-old schoolchildren, insufficient physical exercise, less than excellent marks in mathematics, weak SOC, insufficient social support from teachers, and perceived various problems in class climate associated with perception of poor health. Identification of behavioural problems in early childhood helps to identify the children at risk of ill-being and poor SOC in adolescence since problems seem to persist unchanged until adolescence. The 13-item SOC scale aimed at adults is applicable to adolescents of 12 years of age or older and the SOC scale is a useful tool in identifying adolescents in need of supportive interventions.

Síntese de biodiesel: uma proposta contextualizada de experimento para laboratório de química geral

The contextualized understanding of concepts in Chemistry by students from other areas is a challenging task. In this experiment, the synthesis of biodiesel is done by base catalyzed transesterification of refined soy oil with methanol at room temperature and common glassware found in any chemistry laboratory. The proposal permits introducing several concepts, such as that of emulsion, viscosity and catalysis to illustrate an activity based on an actual problem. In this didactic approach, some common problems of biodiesel production, such as soap formation and phase separation, are introduced into the procedure in order to raise questions and motivate the students to participate in the experimental work and stimulate reflections about critical aspects of biodiesel production. This experiment was carried out in the first semester of 2006, in experimental general chemistry taken by physics and agricultural, civil and chemical engineering students of UNICAMP.

Conceitos de química dos ingressantes nos cursos de graduação do Instituto de Química da Universidade de São Paulo

A diagnostic instrument was developed to evaluate the basic chemistry concepts held by freshmen students of the three Chemistry undergraduate courses offered by the University of São Paulo. The instrument minimizes the use of algorithms or memorization by students and values high-order cognitive skills. Analysis of the students' performances reveals systematic use of "displacement reaction" as an algorithm and a mechanical use of Le Chatelier's Principle. Failure in comprehending the chemical equation and chemical language drives students to alternative models for chemical reactions in aqueous solution. For instance, reaction would occur between "ionic pairs" and/or between species situated in separate compartments.

Enabling constructive alignment in programming instruction

In this thesis, simple methods have been sought to lower the teacher’s threshold to start to apply constructive alignment in instruction. From the phases of the instructional process, aspects that can be improved with little effort by the teacher have been identified. Teachers have been interviewed in order to find out what students actually learn in computer science courses. A quantitative analysis of the structured interviews showed that in addition to subject specific skills and knowledge, students learn many other skills that should be mentioned in the learning outcomes of the course. The students’ background, such as their prior knowledge, learning style and culture, affects how they learn in a course. A survey was conducted to map the learning styles of computer science students and to see if their cultural background affected their learning style. A statistical analysis of the data indicated that computer science students are different learners than engineering students in general and that there is a connection between the student’s culture and learning style. In this thesis, a simple self-assessment scale that is based on Bloom’s revised taxonomy has been developed. A statistical analysis of the test results indicates that in general the scale is quite reliable, but single students still slightly overestimate or under-estimate their knowledge levels. For students, being able to follow their own progress is motivating, and for a teacher, self-assessment results give information about how the class is proceeding and what the level of the students’ knowledge is.

”Hei, mä opin tän asian enkuks!” Toimintatutkimus ympäristötiedon ainesisältöjen ja vieraan kielen oppimisesta sekä opettamisesta englanninkielissä oppituokioissa

Tämä kvalitatiivinen toimintatutkimus sai lähtökipinän opettajan tarpeesta kehittää englannin kielen opetustaan suuntaan, joka innostaisi oppijoita opiskelemaan ja tuottamaan vierasta kieltä rohkeasti. Tutkimuksen tarkoituksena oli selvittää, mitä muutoksia oppijoissa ilmenee, kun perinteiseen vieraan kielen opetukseen sisällytetään kahden lukuvuoden ajan oppituokioita, joissa ympäristötiedon ainesisältöjä opetetaan vieraalla kielellä. Kiinnostuksen kohteena oli tutkia, ilmeneekö oppijoilla muutoksia ainesisältöjen hallinnassa, englanninkielisen ympäristötiedon sanavaraston karttumisessa, kielitaidon kehittymisessä sekä asenteessa oppituokioita ja englannin kieltä kohtaan yleensä. Tutkimuksen tarkoituksena oli myös luoda toimivaa käytäntöä opettajalle toteuttaa ainesisältöjen opettamista vieraalla kielellä, josta kansainvälisesti käytetään termiä Content and language integrated learning (CLIL). Tutkimus oli kahden vuoden pitkittäistutkimus, joka toteutettiin lukuvuosina 2008–2010. Tutkimusjoukko koostui 18:sta (11 poikaa ja 7 tyttöä) neljättä luokkaa aloittavasta oppijasta. Vertailuryhmään kuului 22 musiikkiluokan oppijaa (6 poikaa ja 16 tyttöä). Tutkija opetti molemmille ryhmille englannin kieltä kaksi viikkotuntia. Englanninkieliset oppituokiot toteutettiin englannin tuntien yhteydessä noin kerran viikossa. Kerrallaan tuokio kesti 15–20 minuuttia. Tutkimusaineistoa, joka koostuu sekä kvalitatiivisesta että kvantitatiivisesta aineistosta, kerättiin eri tavoin: tutkija keräsi havaintomateriaalia päiväkirjaansa koko tutkimuksen ajan, oppijoita testattiin kuusi kertaa tutkimuksen aikana sekä itsearvio- ja asennekyselyjä toteutettiin kahdesti. Tutkimusaineiston pohjalta saatiin selviä tutkimustuloksia, joiden mukaan CLIL-opetus vaikutti oppijoihin positiivisesti: ympäristötiedon ainesisältöjä opittiin, englanninkielinen ympäristötiedon sanavarasto laajeni ja vierasta kieltä käytettiin rohkeammin kuin aiemmin. Kommunikoidessa huomio kiinnitettiin kielen tarkkailun sijasta asiasisältöön. Oppijat suhtautuivat englanninkielisiin oppituokioihin positiivisesti ja englannin osaaminen koettiin tärkeäksi. Tässäkin kokeilussa CLIL osoittautui joustavaksi metodiseksi lähestymistavaksi, joka taipuu käyttökelpoiseksi käytännön teoriaksi soveltuen monenlaisille oppijoille.

The Role of Non-Coercive Influence Tactics in Online Marketing

This thesis examines the effectiveness of non-coercive influence tactics in the context of consumer online behaviour. The objective of this study is to develop a comprehensive understanding of consumer online behaviour and the role of information types in affecting the consumer’s cognitive responses and behavioural outcomes. The theoretical part of the study examines the academic literature on consumer online behaviour and influence tactics used both in traditional buyer/seller relationships as well as in relationships mediated by online technologies. The empirical part of the study is carried out with four experiments that utilise non-coercive influence tactics to affect online consumer behaviour. The consumers included in this study are 18-28 year-old structural and civil engineering students in Finland, United Kingdom, United States and India. The findings suggest that non-coercive influence tactics are applicable in the online marketing context and generate cognitive responses of site awareness, site involvement and exploratory behaviour which subsequently results in behavioural outcomes of compliance, eWOM and site abandonment.

Opiskelumotivaation selvitystyö sähkötekniikan opinnoissa Lappeenrannan teknillisessä yliopistossa

Opiskelumotivaatio on monimutkainen käsite, johon vaikuttavat sekä sisäiset että ulkoiset tekijät. Motivaatiota voidaan tarkastella useasta eri näkökulmasta. Työn tarkoituksena on selvittää sähkötekniikan opiskelijoiden motivaation tilanne. Myös opetuksen käytännön tekijöiden vaikutus opiskeluun selvitetään. Työ toteutettiin määrällisenä kyselytutkimuksena; kysely lähetettiin sähkötekniikan opiskelijoille syksyllä 2014. Tuloksia verrattiin lisäksi muihin aihetta käsitteleviin tutkimuksiin. Tutkimuksessa havaittiin sähkötekniikan opiskelijoiden motivaation olevan hyvää tasoa. Sähkötekniikan opetus on yhteisöllistä ja opetushenkilökunta helposti lähestyttävää. Kyselyn vastauksista löytyi joitakin kursseja, joiden suorittaminen on opiskelijoille epämieluisaa. Vastaavasti tietyt kurssit ovat suosittuja suoritustapansa ja arvostelunsa takia. Opiskelumotivaation kannalta havaittiin palautteen ja opintojen tärkeyden kokemisen olevan merkittäviä tekijöitä. Sähkötekniikan opetus vaikuttaisi olevan hieman erilaista kuin muu opetus Lappeenrannan teknillisessä yliopistossa. Käytännön asioiden ja työelämän taitojen opetusta olisi lisättävä.

The importance of package design to Japanese consumers: The role of visual and informational elements of package design in decision making

The importance of package design as a marketing tool is growing as the competition in retail environment increases. However, there is a lack of studies on how each element of package design affects consumer decisions in different countries. The objective of this thesis is to study the role of package design to Japanese consumers. The research was conducted through an experiment with a sample of 37 Japanese female participants. They were divided into two groups and were given different tasks: one group had to choose a chocolate for themselves, and the other for a group of friends. The participants were presented with 15 different Finnish chocolate boxes to choose from. The qualitative data was gathered through observation and semi-structured interviews. In addition, data from questionnaires was quantified and all the data was triangulated. The empirical results suggest that visual elements strongly affect the decision making of Japanese consumers. Image was the most important element which acted as both, a visual and an informational aspect in the experiment. Informational elements on the other hand have little effect, especially when the context is written in a foreign language. However, informational elements affected participants who were choosing chocolates for a group of friends. A unique finding was the importance of kawaii (cuteness) to Japanese consumers.

Efficacy of cognitive behavioral therapy in reducing psychiatric symptoms in patients with implantable cardioverter defibrillator: an integrative review

This article is a systematic review of the available literature on the benefits that cognitive behavioral therapy (CBT) offers patients with implanted cardioverter defibrillators (ICDs) and confirms its effectiveness. After receiving the device, some patients fear that it will malfunction, or they remain in a constant state of tension due to sudden electrical discharges and develop symptoms of anxiety and depression. A search with the key words “anxiety”, “depression”, “implantable cardioverter”, “cognitive behavioral therapy” and “psychotherapy” was carried out. The search was conducted in early January 2013. Sources for the search were ISI Web of Knowledge, PubMed, and PsycINFO. A total of 224 articles were retrieved: 155 from PubMed, 69 from ISI Web of Knowledge. Of these, 16 were written in a foreign language and 47 were duplicates, leaving 161 references for analysis of the abstracts. A total of 19 articles were eliminated after analysis of the abstracts, 13 were eliminated after full-text reading, and 11 articles were selected for the review. The collection of articles for literature review covered studies conducted over a period of 13 years (1998-2011), and, according to methodological design, there were 1 cross-sectional study, 1 prospective observational study, 2 clinical trials, 4 case-control studies, and 3 case studies. The criterion used for selection of the 11 articles was the effectiveness of the intervention of CBT to decrease anxiety and depression in patients with ICD, expressed as a ratio. The research indicated that CBT has been effective in the treatment of ICD patients with depressive and anxiety symptoms. Research also showed that young women represented a risk group, for which further study is needed. Because the number of references on this theme was small, further studies should be carried out.

Utilising student profiles in mathematics course arrangements

This thesis develops a method for identifying students struggling in their mathematical studies at an early stage. It helps in directing support to students needing and benefiting from it the most. Thus, frustration felt by weaker students may decrease and therefore, hopefully, also drop outs of potential engineering students. The research concentrates on a combination of personality and intelligence aspects. Personality aspects gave information on conation and motivation for learning. This part was studied from the perspective of motivation and self-regulation. Intelligence aspects gave information on declarative and procedural knowledge: what had been taught and what was actually mastered. Students answered surveys on motivation and self-regulation in 2010 and 2011. Based on their answers, background information, results in the proficiency test, and grades in the first mathematics course, profiles describing the students were formed. In the following years, the profiles were updated with new information obtained each year. The profiles used to identify struggling students combine personality (motivation, selfregulation, and self-efficacy) and intelligence (declarative and procedural knowledge) aspects at the beginning of their studies. Identifying students in need of extra support is a good start, but methods for providing support must be found. This thesis also studies how this support could be taken into account in course arrangements. The methods used include, for example, languaging and scaffolding, and continuous feedback. The analysis revealed that allocating resources based on the predicted progress does not increase costs or lower the results of better students. Instead, it will help weaker students obtain passing grades.

El factor edad en la adquisición del español como lengua extranjera : análisis comparativo entre estudiantes de sexto grado de primaria y universitarios sobre el uso del par preposicional a/ en

Résumé L’hypothèse de la période critique, émise par Lenneberg dans les années 60, affirmait qu’un enfant pouvait acquérir une langue seconde, sans difficulté, environ jusqu’à l’âge de la puberté. Après cette période, l’apprentissage d’un autre idiome serait difficile, dû à la latéralisation du cerveau. En même temps, les travaux de Chomsky enrichirent cette théorie avec l’idée de la Grammaire universelle, laquelle établit que nous possédons tous, dès la naissance, les éléments linguistiques universels qui nous permettent d’acquérir une langue maternelle. Tant que la Grammaire universelle est active, notre langue maternelle se développe et c’est pourquoi, si nous apprenons une autre langue pendant cette période, l’acquisition de celle-ci se produit de manière presque naturelle. Pour cette raison, plus une langue est apprise tôt, plus elle sera maîtrisée avec succès. En nous appuyant sur ce cadre théorique ainsi que sur l’Analyse d’erreurs, outil qui permet au professeur de prédire quelques erreurs avec la finalité de créer des stratégies d’apprentissage d’une langue seconde, nous tenterons de vérifier dans le présent travail si l’âge est un facteur qui influence positivement ou négativement l’apprentissage d’une langue seconde, l’espagnol dans ce cas-ci, par le biais de l’analyse comparative des prépositions a/ en dans deux groupes d’étudiants différents.
