The study of students' use of representations is one of the main topics of physics education research and is guided by the overarching field of semiotics. In this paper we compare two semiotic frameworks, one coming from didactics of mathematics and one from physics education research; "the theory of registers of semiotic…

National goals and performance standards were introduced in Sweden during the 1990s as part of a curriculum reform. The intention was to detect shortcomings among students and provide support to those students who did not reach the passing grade in one (or several) subject/s. Despite this reform, approximately one-fourth of the students do not…

In many countries' policy documents and curricula, teachers in the subject areas of science, social science and language are encouraged to collaborate on cross-curricular issues such as sustainable development (SD). This study is conducted in secondary schools (compulsory years 7-9) in Sweden and investigates the similarities and differences in…

Researchers and policy-makers have recognized the importance of including and promoting socioscientific argumentation in science education worldwide. The Swedish curriculum focuses more than ever on socioscientific issues (SSI) as well. However, teaching socioscientific argumentation is not an easy task for science teachers and one of the more…

Peer-assisted learning has gained momentum in a variety of disciplines, including medical education. In Gothenburg, Sweden, medical students who have finished their compulsory anatomy courses have the option of working as teaching assistants (TAs). Teaching assistants provide small group teaching sessions as a complement to lectures given by…

Almost 700 Swedish and South African students from the upper secondary school and first-term chemistry university level responded to our survey on concepts of chemical bonding. The national secondary school curricula and most common textbooks for both countries were also surveyed and compared for their content on chemical bonding. Notable…

Recently, the South African Institute of Physics undertook a major review of university physics education. The report highlighted the necessity for further transformation of the teaching of physics, particularly in relation to the teaching of under-prepared students. In this article we examine how physics lecturers in South Africa reported how…

It is all too common, given the considerable day-to-day challenges facing those involved in education, to focus on the here and now rather than look further afield. The authors of this article have been fortunate enough to see "primary science" in a wide range of international settings, from Nigeria to Chile, North America and Canada,…

In this study we investigate students' ability to discern conceptual variation and the use of multiple models in genetics when reading content-specific excerpts from biology textbooks. Using the history and philosophy of science as our reference, we were able to develop a research instrument allowing students themselves to investigate the…

In this study, the purpose is to develop and illustrate a method that facilitates investigations of students' learning processes in classroom discussions about socioscientific issues. The method, called transactional argumentation analysis, combines a transactional perspective on meaning making based on John Dewey's pragmatic philosophy and an…

The purpose of this paper is to present the mechanism for effective communication when the mathematical objects of learning are equations and functions. The presentation is based on data collected while the same object of learning is presented in two classes, and it includes two teachers and 45 students. Among other things, the data consists of…
