Making sense of global warming: Norwegians appropriating knowledge of anthropogenic climate change

This paper studies how people reason about and make sense of human-made global warming, based on ten focus group interviews with Norwegian citizens. It shows that the domestication of climate science knowledge was shaped through five sense-making devices: news media coverage of changes in nature, particularly the weather, the coverage of presumed experts' disagreement about global warming, critical attitudes towards media, observations of political inaction, and considerations with respect to everyday life. These sense-making devices allowed for ambiguous outcomes, and the paper argues four main outcomes with respect to the domestication processes: the acceptors, the tempered acceptors, the uncertain and the sceptics.     

Environmental education in a ‘green classroom’

The ‘Green Classroom’ in the Botanical Garden of Ulm is an experiential learning forum outside school. Its educational concept is based on experimental learning and is geared towards expanding biological knowledge and developing positive attitudes towards small animals such as invertebrates and insects. The attitudes of 68 school students towards small animals, before and after they visited the ‘Green Classroom’, were assessed and the answers they gave in their questionnaires were compared with those of 60 students froma control group that was not yet exposed to this learning environment. Although the students spent only one morning in the ‘Green Classroom’, some of their attitudes towards small animals improved after their visit. These studies underscore the necessity for direct observation and familiarization of the environment including small animals such as invertebrates and insects for appreciating issues related to biodiversity and conservation.     

The Development of Scientific Thinking in Elementary School: A Comprehensive Inventory

The development of scientific thinking was assessed in 1,581 second, third, and fourth graders (8‐, 9‐, 10‐year‐olds) based on a conceptual model that posits developmental progression from naïve to more advanced conceptions. Using a 66‐item scale, five components of scientific thinking were addressed, including experimental design, data interpretation, and understanding the nature of science. Unidimensional and multidimensional item response theory analyses supported the instrument's reliability and validity and suggested that the multiple components of scientific thinking form a unitary construct, independent of verbal or reasoning skills. A partial credit model gave evidence for a hierarchical developmental progression. Across each grade transition, advanced conceptions increased while naïve conceptions decreased. Independent effects of intelligence, schooling, and parental education on scientific thinking are discussed.     

The role of international student mobility in hiring decisions. A vignette experiment among German employers

By virtue of the internationalisation of economies, international student mobility is considered increasingly important for professional careers. However, most studies focus on the supply-side by using graduate surveys, which face problems of graduates’ self-selection. Other studies on employers’ opinions often lack rigour analysis and report ambiguous results. Combining a general matching approach with theories on human capital and sorting, studying abroad can impact both the decision on hiring and the decision on international assignment. To solve problems of endogeneity and to consider employers’ perspectives directly, a vignette experiment is applied. Hypothetical applicants, with systematically varied higher education credentials, are randomly presented to a sample of German employers, in order to simulate a screening situation. Results show that study abroad experience is more important for international assignment, than for hiring. While it does not interact with final grades, it can be markedly substituted by professional work experience, when employers consider international assignment. In turn, professional work experience can be somewhat substituted by study abroad experience, when employers consider hiring. At least in the German institutional context, international student mobility may rather serve as a signal of transnational human capital, than as a signal of general job-performance.     

International student mobility in a German and Portuguese university: Which factors in the host institution matter?

In a globalising world, international mobility in higher education is an important phenomenon for students and higher education institutions. It is therefore essential to understand the factors that determine international students' satisfaction with higher education institutions that serve as hosts. Through research of an exploratory, quantitative nature, this study presents results from a survey among 289 incoming international students in two universities in Germany and Portugal. Our findings show that the factor we define as educational experience was an important determinant of student satisfaction. Furthermore, the appraisal of academic reputation is dependent on the university. We conclude that satisfaction with academic factors is more important for international students than satisfaction with non-academic aspects.     

Towards a learning progression of energy

This article presents an empirical study on an initial learning progression of energy, a concept of central importance to the understanding of science. Learning progressions have been suggested as one vehicle to support the systematic and successful teaching of core science concepts. Ideally, a learning progression will provide teachers with a framework to assess students' level of understanding of a core concept and to guide students towards a more sophisticated level of understanding. Taking existing research as a point of departure, developing a learning progression involves recurring cycles of empirical validation and theoretical refinement. In this article, we report about our efforts in working towards a learning progression of energy. First, we derived an initial learning progression by utilizing existing curriculum, research on students' understanding, and development of students' understanding of energy. Second, we used these sources of guidance to develop a robust measurement instrument, the Energy Concept Assessment (ECA), based on multiple choice questions. Third, we utilized this instrument to assess the understanding of N = 1,856 students from three different grade levels, Grades 6, 8, and 10. Findings provided evidence that students from Grade 6 mostly obtain an understanding of energy forms and energy sources. Students of Grade 8 additionally demonstrate an understanding of energy transfer and transformation, whereas only students of Grade 10, and then only some of these students, achieve a deeper understanding of energy conservation. We discuss the implications of our findings against the background of existing research on students understanding of energy. Finally, further steps in working towards a learning progression of energy are identified. Zusammenfassung: Der vorliegende Artikel beschreibt den ersten Schritt in der Entwicklung und Validierung einer Learning Progression für das Energiekonzept; einem Konzept, das zentral für die Entwicklung eines tiefergehenden Versta¨?ndnisses der Naturwissenschaften ist. Learning Progressions sollen das das systematische und erfolgreiche Unterrichten zentraler naturwissenschaftlicher Konzepte unterstützen. Idealerweise sollen Learning Progressions Lehrkräften eine Rahmen bieten, den Entwicklungsstand ihrer Schülerinnen und Schüler hinsichtlich des Verständnisses zentraler naturwissenschaftlicher Konzepte einzuschätzen und Unterricht so zu gestalten, dass er die Entwicklung eines elaborierten Verständnisses befördert. Die Entwicklung einer Learning Progression beginnt mit der theoretischen Begründung einer vorläufigen Learning Progression, gefolgt von iterativen Zyklen empirischer Validierung und Überarbeitung. In diesem Artikel berichten wir über unsere Arbeiten zur Entwicklung einer Learning Progression für das Energiekonzept. Im Rahmen dieser Arbeiten wurde zunächst ausgehend von vorliegenden Befunden zum Verständnis und der Entwicklung des Verständnisses von Energie eine vorläufige Learning Progression begründet. Im zweiten Schritt wurde auf Grundlage der Learning Progression ein entsprechendes Instrument auf Basis von Multiple‐Choice‐Aufgaben entwickelt – das Energy Concept Assessment (ECA). Im dritten und letzten Schritt wurde das Instrument eingesetzt, um das Verständnis von Energie bei N = 1856 Schülerinnen und Schülern der Jahrgänge 6, 8 und 10 zu erfassen. Die Ergebnisse unserer Untersuchung legen nahe, dass Schülerinnen und Schüler aus Jahrgang 6 im Wesentlichen über ein Verständnis von Energieformen und –quellen verfügen. Schülerinnen und Schüler aus Jahrgang 8 zeigen darüber hinaus ein Verständnis von Energieumwandlung und –transport. Ein Verständnis von Energieerhaltung ist nur von Schülerinnen und Schüler aus Jahrgang 10 und dann auch nur von einem Teil dieser Schülerinnen und Schüler zu erwarten. Vor dem Hintergrund dieser Ergebnisse und der bisherigen Forschung zum Energieverständnis, diskutiert der Artikel weitere Schritte für die die Entwicklung einer Learning Progression für das Energiekonzept. © 2012 Wiley Periodicals, Inc.

The interplay between students' motivational profiles and science learning

Students' motivation plays an important role in successful science learning. However, motivation is a complex construct. Theories of motivation suggests that students' motivation must be conceptualized as a motivational system with numerous components that interact in complex ways and influence metacognitive processes such as self-evaluation. This complexity is further increased because students' motivation and success in science learning influence each other as they develop over time. It is challenging to study the co-development of motivation and learning due to these complex interactions which can vary widely across individuals. Recently, person-centered approaches that capture students' motivational profiles, that is, the multiplicity of motivational factors as they co-occur in students, have been successfully used in educational psychology to better understand the complex interplay between the co-development of students' motivation and learning. We employed a person-centered approach to study how the motivational profiles, constructed from goal-orientation, self-efficacy, and engagement data of N = 401 middle school students developed over the course of a 10-week energy unit and how that development was related to students' learning. We identified four characteristic motivational profiles with varying temporal stability and found that students' learning over the course of the unit was best characterized by considering the type of students' motivational profiles and the transitions that occurred between them. We discuss implications for the design and implementation of interventions and future research into the complex interplay between motivation and learning.
