Past research repeatedly revealed students' struggles to understand chemical equilibria, especially concerning their dynamic nature. Black-box simulations have proven to be helpful here. However, the effect is strongly dependent on the quality of teaching, the design principles of which are not yet fully known. One aspect of debate concerns the…

Academic self-concept is understood as a multidimensional, hierarchical construct. Multidimensionality refers to the subject-specific differentiation of academic self-concepts, whereas hierarchy refers to the aggregation of more specific facets of self-concepts into more general ones. Previous research demonstrated that students distinguish…

Participation in science is unevenly distributed among secondary school students, depending on gender, social class, and ethnicity. In the present study, the influence of the home environment on students' chemistry self-concept is investigated as a factor for explaining participation in science. For this, the sociological lens of chemistry capital…

Juniorstudy is a concept of the University of Rostock, which can be used by school students before starting their time at the University. Thus, it is an instrument of supporting the choice of study direction. Moreover, we have been able to show in our last cohort, that using Juniorstudy courses also helps to significantly enhance the knowledge…

Science standards of different countries introduced disciplinary core ideas and crosscutting concepts--such as energy--to help students develop a more interconnected science understanding. As previous research has mostly addressed energy learning in specific disciplinary contexts, this study targets students' cross-disciplinary understanding of…

A case is described of the development of a lesson plan for 10th grade (age range 15-16) chemistry classes on the chemistry of shower gels. The lesson plan follows a socio-critical and problem-oriented approach to chemistry teaching. This means that, aside from learning about the basic chemistry of the components making up modern shower gels in…

In 2004 national educational standards for chemistry were implemented in Germany. While the standards describe different competencies to be reached after grade 10, no compulsory contents are defined. The contents are defined by the different German states individually. This means that there are no defined common topics taught in all states that…

This paper describes the development of different lesson plans dealing with authentic and controversial socio-scientific issues in the framework of climate change. These lesson plans orient themselves along the socio-critical, problem-oriented approach to science teaching. They deal with the use of bioethanol as an alternative fuel and with the…

This paper discusses a chemistry lesson plan on potato crisps for 10th grade (age range 15-16) chemistry classes in Germany. The lesson plan focuses on the discussion about low-fat and low-carb diets as they are presented in everyday media such as TV or newspapers in Germany. The discussion follows a socio-critical and problem-oriented approach to…

A total of three hundred and fifteen (n = 315) gifted students from the 10th and 12th grade from the United States (n = 102), China (n = 125) and Germany (n = 88) were surveyed regarding their motivation and self-regulation in chemistry learning. A 3 x 2 x 2 MANOVA revealed "nation" as having the largest major effect on these variables.…
