Die vorliegende Arbeit untersucht die Testteilnahmemotivation von Schülerinnen und Schülern in großangelegten Schulleistungsstudien. Es wurde ein theoretisches Erwartung-Wert-Anstrengung-Modell der Testteilnahmemotivation herausgearbeitet, das in drei empirischen Studien überprüft wurde. Dabei wurde das komplexe Beziehungsgefüge zwischen Erfolgserwartung, dem wahrgenommene Wert des Tests, Anstrengungsbereitschaft und Testleistung untersucht. Datengrundlage der Studie I bildete die erste PISA-Erhebung aus dem Jahr 2000, in der die Testteilnahmemotivation durch Fragen zur Anstrengungsbereitschaft und zum wahrgenommenen Wert des Tests erhoben wurde. In Studie II und III gaben die Jugendlichen, die an der Ländervergleichsstudie im Jahr 2012 teilnahmen, Einschätzungen zu ihrer Erfolgserwartung, dem wahrgenommenen Wert des Tests und ihrer Anstrengungsbereitschaft ab. Die Ergebnisse zeigen, dass Testteilnahmemotivation zur Erklärung individueller Unterschiede in der Testleistung beiträgt (Studie I), auch wenn diverse Hintergrundinformationen der Teilnehmenden berücksichtigt werden (Studie III). Die theoretisch angenommenen Beziehungen im Erwartung-Wert-Anstrengung-Modell wurden fast vollständig bestätigt: Vor allem der wahrgenommene Wert, aber auch die Erwartungen sagten die berichtete Anstrengungsbereitschaft der Teilnehmenden vorher; die Erfolgserwartung und die Anstrengungsbereitschaft wiesen einen Zusammenhang mit der Testleistung auf (Studie II). Im Verlauf eines Leistungstests berichteten die Teilnehmenden im Durchschnitt eine Abnahme in der Anstrengung und dem Wert sowie einen stabilen Verlauf ihrer Erfolgserwartung. Zur Erklärung der Testleistung trug neben der anfänglichen Erfolgserwartung und Anstrengungsbereitschaft auch die Veränderung in der Erfolgserwartung bei (Studie III). Für eine hohe Testleistung ist es wichtig, dass die Teilnehmenden den Test motiviert beginnen und während des Tests selbstsicher bezüglich ihrer Erfolgserwartung bleiben. / The thesis investigates effects of test-taking motivation on test performance in low-stakes assessments. An expectancy-value-effort model of test-taking motivation was developed and tested in three empirical studies. The studies investigated the complex relationship between expectancy for success, perceived value of the test, test-taking effort, and test performance. The database of study I is the first PISA study. Test-taking motivation was assessed with questions about effort and the perceived value of the test. Study II and III are premised on the national assessment study in the year 2012. The students reported their expectancy for success, their perceived value of the test, and their test-taking effort. Overall, the results showed that test-taking motivation explained test performance (study I) although controlling for various students’ background characteristics (e.g., socio-economic background, study III). We found support for nearly all of the theoretically assumed relationships in the expectancy-value-effort model: Expectancy for success and perceived value of the test explained test-taking effort; expectancy for success and test-taking effort had the most pronounced effects on test performance (study II). The students reported, on average, a stable course of expectancy for success over the testing session; perceived importance of the test and test-taking effort slightly decreased within the testing session. The initial expectancy for success and the initial test-taking effort as well as change in expectancy for success explained students’ test performance. Above all, it is crucial that students begin the test with a high level of test-taking motivation and remain confident about a successful test completion to the end of the testing session.

Rural Ethiopia rolled-out a program for the establishment of farmers’ collective action groups known as ‘Farmers’ Development Groups’ (FDGs), in 2007, based on presumed common interest of smallholder farmers. Although the government trusts that FDGs fetch fast and widescale agricultural transformation as part of the participatory agricultural extension system, systematic study and evidence on what motivates smallholder farmers to act collectively, the group dynamics, long term impact and transformative potential of the agricultural extension groups is scarce. Using the expectancy-value theory in social-psychology, this study explores what drives smallholders to act collectively; their participation level and benefits in groups, particularly for women and the youth; and the extent to which farmers’ groups attain intended agricultural transformation goals of productivity and commercialization. The study collected a mix of qualitative and quantitative data in 2016, through 46 key informant interviews; 8 focus group discussions with farmers, and a survey of randomly selected 120 smallholder farmers (30 percent women) in four sample woredas (districts) of Ethiopia. The findings of the study are drawn through a content analysis, and descriptive and correlation analysis of the qualitative and quantitative data, respectively. The study findings show that social identity, and not ‘common interest’ motivates smallholder farmers to join and participate in FDGs. The study provides evidence that participation in FDGs enhances smallholder farmers’ adoption and use of agricultural technologies, where 96 and 84 percent of the farmers who received extension messages in the group on crop and livestock production, respectively, applied the message. Consequently, by 2015 more than 85 percent of the survey respondent farmers reported above 10 percent increase in crop and livestock productivity. Nevertheless, the nature of the incremental changes brought by the collective actions are not transformative, nor sustainable. Extension groups have limited contribution to commercialization of smallholders, where only 20 percent of the FDG members participate in output marketing. More so, FDGs avail limited collective opportunity for the landless youth, and married female farmers in a rural society where difference in power, status and privilege prevail. It also limits deviation of thought among the rural community. Limited access to inputs and technology; large family size; limited access to farm land; over dependence of the extension system on ‘model’ farmers and public extension agents, and poorly designed sustainability features bound the transformative potential of FDGs. The study forwards a set of five recommendations to unleash the potential of FDGs: reconsider the group design to be identity congruent; ensure inclusiveness for young and female farmers; empower and motivate voluntary group leaders; encourage collective marketing and; invest in sustainability features of the group. / Development Studies / Ph.

<p>  </p> <p>Food system STEM projects have the capacity to motivate high school students in urban schools. This study explored food as a context to engage students because everyone interacts with food on a daily basis and has had cultural experiences related to food. An integrated STEM approach in combination with a systems thinking approach challenged students to make transdisciplinary connections, view problems from different perspectives, analyze complex relationships, and develop 21st-century and career skills (Hilimire et al., 2014; Nanayakkara et al., 2017). The purpose of this study was to describe and explain the relevance students perceive in Ag+STEM content by measuring high school students' self-efficacy, intrinsic value, attainment value, cost value, and utility value after participating in a food system STEM project. The study was informed by Eccles and Wigfield’s (2020) Situated Expectancy Value Theory. The convenience sample of this study was comprised of high school students from metropolitan area schools. High school students completed a food system STEM project with a food system context. Quantitative data was collected using the developed Food System Motivation questionnaire. Data were collected through a retrospective pre-test and a post-test. Descriptive statistics were used to analyze the data including means and standard deviations. Relationships were explored by calculating correlations.</p> <p>There were four conclusions from this study. First, high school students were somewhat interested, felt it was important to do well, and agreed there were costs regarding participation in the food system STEM project. Second, high school students reported higher personal and local utility value motivation after completing the food system STEM project. Third, high school students were somewhat self-efficacious in completing the project tasks and completing the project tasks informed by their cultural identity and experiences. Fourth, intrinsic value and attainment value motivation (independent variables) were related to personal and local utility value motivation and project and cultural self-efficacy motivation (dependent variables). Implications for practice and recommendations for future research were discussed.</p>

Syftet med den här studien var att undersöka vilka arbetssätt lärare upplever bidrar till att elever känner motivation till läsning av skönlitteratur samt att ta reda på vilka utmaningar lärare står inför i det arbetet. Studien genomfördes med en kvalitativ metod med semistrukturerade intervjuer med tio informanter. Den tidigare forskningen som ligger till grund för studien handlar om hur skönlitteratur och läsning hänger ihop, hur läsning och motivation hänger ihop samt hur lärare arbetar med läsning. Studiens teoretiska grund bygger på den sociokulturella teorin av Lev Vygotskij samt expectancy-value theory som är grundad av Jacquelynne Eccles och hennes kollegor. Det resultat som studien visade var att lärarna som deltog i studien har flera metoder för att försöka ge eleverna motivation till läsning av skönlitteratur som placering, arbete med val av böcker, använda yttre aktörer och högläsning. De utmaningar som lärare upplever beskriver de som arbetet mot hemmen, elevens sociala situation, gruppstorleken samt dynamiken i gruppen. / The purpose of this study was to explore what working methods teachers consider having a contribution to the feeling of motivation in students regarding reading fiction and also what challenges teachers face with this work. This study was conducted using a qualitative method with semi-structured interviews with ten informants. The previous research that is the foundation for this study reflects how reading of fiction and reading are connected, how reading and motivation are connected and how teachers work with reading in the classroom. The study's theoretical basis is based on the sociocultural theory of Lev Vygotsky and expectancy-value theory, which was founded by Jacquelynne Eccles and her colleagues. The result of this study showed that the teachers that were participating used multiple methods in their work trying to motivate students to read fiction. Among these are placement in the classroom, thought into choosing books, the usage of external actors and reading aloud. The challenges that teachers face are described by the informers in this study as the collaboration with the home, the students social situation, group size and the dynamic of the group.

Au cours des dernières années, les communautés virtuelles de patients se sont énormément développées sur l'Internet. Ces communautés permettent des échanges fréquents entre les patients, qui peuvent partager des informations liées à la santé dans un environnement interactif. Alors que beaucoup s'accordent sur l'opportunité représentée par ces communautés pour ses utilisateurs, les connaissances sur ce qui détermine l'action collective en ligne des patients ainsi que sur les fondamentaux de l'action collective en ligne dans ces espaces virtuels sont relativement peu développées. En conséquence, ce travail doctoral examine les raisons pour lesquelles les patients interagissent entre eux et comment ils procèdent. En nous appuyant sur le modèle du comportement orienté vers un but, la théorie de la valeur de l'attente, la théorie des forces du champ, les concepts de dons et les interviews menées, nous avons développé un modèle qui examine les interactions en ligne des patients dans un contexte d'action collective en ligne. Une approche multi-méthode, qualitative et quantitative, permet d'explorer les interactions des patients et de mesurer les déterminants de l'action collective en ligne sur ces espaces virtuels. L'analyse qualitative de 54 entretiens menés avec des patients, des proches de patients, des professionnels de la santé 2.0, des médecins et des soignants permet d'affiner le modèle de recherche, qui a ensuite été testé au travers d'une enquête quantitative auprès de 269 patients. Cette recherche contribue à la recherche en systèmes d'information en augmentant nos connaissances sur la dynamique individuelle et les interactions qui entourent les communautés de patients en ligne. / Over the last few years, virtual patients’communities have been developing tremendously over the Internet. These Web 2.0 communities allow frequent interactions among patients, who can share health-related information within an interactive environment. While many agree on the opportunity represented by those communities for its users, we know very little about what determines patients’ online collective action, specifically on virtual communities as well as the fundamentals of online collective action in these virtual spaces. Accordingly, this doctoral work examines why patients interact with others and how they interact on topics related to their disease through these virtual communities. Drawing on the goal-directed behavior (MGB), the expectancy-value (EVT) theories, the field force theory, gift concepts and field interviews, we have developed a model for examining patients’ online interactions and identified gift-giving behaviors in the context of online collective action. A multi-method, qualitative and quantitative approaches, enables us to explore patients’ interactions and measures the determinants of online collective action on these virtual spaces. The qualitative analysis of 54 interviews conducted with patients, patient’s relatives, Health 2.0 professionals, doctors and caregivers allows refining the research model, which has then been tested through a survey handled with 269 patients, members of patient’s communities. This research contributes to IS research by increasing our knowledge regarding the individual dynamics and interactions that surround online patients’ communities.
