Multiple external representations (MERs) are useful for teaching complex content in science education. An open question is whether there is an especially effective way to sequence MERs. On the one hand, the so‐called concreteness fading approach suggests starting instruction with more concrete representations and proceeding stepwise to more idealized representations. The effectiveness of this fading approach is, however, supported mainly by studies in mathematics education, while the results in physics are equivocal. On the other hand, presenting different representations simultaneously may support linking, that is, the comparison and contrast of representations, which may benefit learning. In an experimental classroom study (N = 187), we compared concreteness fading and simultaneous presentation of MERs for learning a challenging physics content in high school, namely, Faraday's law. We found no significant differences between conditions in posttest performance, and an equivalence test with bounds d = −0.5 to 0.5 showed that both approaches performed equally. The results align with previous findings questioning the superiority of concreteness fading over other ways of sequencing MERs. Therefore, facilitating students' understanding of a complex physics content may involve more than determining the optimal order of presenting MERs. We discuss limitations of the present study and implications for future research and practice. [ABSTRACT FROM AUTHOR]

Research indicates that students' interest in science decreases during their school years. To counteract this, a quasi-experimental instructional intervention was designed in which we addressed students' leisure interests to foster their (situational) interest in physics. Students in the intervention group got the opportunity to choose topics matching their leisure interests (e.g. sports, music) and were encouraged to reflect on and discuss the application of principles of semiconductor physics to those topics throughout the intervention with a duration over 11 lessons. The intervention group consisted of 60 students from German high-track schools; another 55 students comprised the control group. The results of a MANCOVA analysis indicate that the instructional intervention succeeded in triggering students' catch and hold component of situational interest during all four phases of the lesson series. Furthermore, behavioural disengagement developed more positively for students in the intervention group, while no significant effects were found for their behavioural engagement, their interest in physics-related activities in leisure or their general interest in physics classes in school. The results suggest that addressing students' leisure interests in physics classes can promote their situational interest and reduce their behavioural disengagement in physics.

This paper examines students' achievement and interest and the extent to which they are predicted by teacher knowledge and motivation. Student achievement and interest are both considered desirable outcomes of school instruction. Teacher pedagogical content knowledge has been identified a major predictor of student achievement in previous research, whereas teacher motivation is considered a decisive factor influencing students' interest. So far, however, most research either focused on knowledge or motivation (both on the students' as well as the teachers' side), rarely investigating them together or examining the instructional mechanisms through which the supposed effects of teacher knowledge and motivation are facilitated. In the present study, N = 77 physics teachers and their classes in Germany and Switzerland are investigated utilizing a multi-method approach in combining data obtained from test-instruments (teacher pedagogical content knowledge, student achievement) and questionnaires (teacher motivation, student interest, student perceived enthusiastic teaching) as well as videotaped instruction (cognitive activation rated by observers). Multi-level structural equation modeling was used to support the assumptions that teacher pedagogical content knowledge positively predicted students' achievement; the effect was mediated by cognitive activation. Teachers' motivation predicted students' interest which was mediated by enthusiastic teaching as perceived by students. Neither did teacher pedagogical content knowledge predict students' interest, nor teacher motivation students' achievement. This implies that in order to improve students' cognitive as well as affective outcomes, both teachers' knowledge but also their motivation need to be considered. © 2016 The Authors.

For the last three decades, moderate constructivism has become an increasingly prominent perspective in science education. Researchers have defined characteristics of constructivist-oriented science classrooms, but the implementation of such science teaching in daily classroom practice seems difficult. Against this background, we conducted a sub-study within the tri-national research project Quality of Instruction in Physics (QuIP) analysing 60 videotaped physics classes involving a large sample of students ( N = 1192) from Finland, Germany and Switzerland in order to investigate the kinds of constructivist components and teaching patterns that can be found in regular classrooms without any intervention. We applied a newly developed coding scheme to capture constructivist facets of science teaching and conducted principal component and cluster analyses to explore which components and patterns were most prominent in the classes observed. Two underlying components were found, resulting in two scales-Structured Knowledge Acquisition and Fostering Autonomy-which describe key aspects of constructivist teaching. Only the first scale was rather well established in the lessons investigated. Classes were clustered based on these scales. The analysis of the different clusters suggested that teaching physics in a structured way combined with fostering students' autonomy contributes to students' motivation. However, our regression models indicated that content knowledge is a more important predictor for students' motivation, and there was no homogeneous pattern for all gender- and country-specific subgroups investigated. The results are discussed in light of recent discussions on the feasibility of constructivism in practice. [ABSTRACT FROM AUTHOR]

The existence of gender-STEM (science, technology, engineering, and mathematics) stereotypes has been repeatedly documented. This article examines physics teachers’ gender bias in grading and the influence of teaching experience in Switzerland, Austria, and Germany. In a 2 × 2 between-subjects design, with years of teaching experience included as moderating variable, physics teachers (N = 780) from Switzerland, Austria, and Germany graded a fictive student's answer to a physics test question. While the answer was exactly the same for each teacher, only the student's gender and specialization in languages vs. science were manipulated. Specialization was included to gauge the relative strength of potential gender bias effects. Multiple group regression analyses, with the grade that was awarded as the dependent variable, revealed only partial cross-border generalizability of the effect pattern. While the overall results in fact indicated the existence of a consistent and clear gender bias against girls in the first part of physics teachers’ careers that disappeared with increasing teaching experience for Swiss teachers, Austrian teachers, and German female teachers, German male teachers showed no gender bias effects at all. The results are discussed regarding their relevance for educational practice and research. [ABSTRACT FROM PUBLISHER]

This article begins with a review of the various roles which computers have played in supporting collaborative learning and argues that, whatever role it plays, technology is not neutral with respect to interactions with and between users. Interfaces to learning environments embody particular representational schemes which have the potential either for competing with representations of the learning domain or for giving access to it. In this respect, the learner-machine interface has 'Epistemic significance' and its design is as important as the design of the materials and activities to which it interfaces. [ABSTRACT FROM AUTHOR]
