The greenhouse effect is a complex scientific phenomenon that plays a crucial role in understanding climate change. Grasping students' understanding of this phenomenon on the content-specific level but also how students' conceptions are organized is vital for effective climate change education. This study addresses both levels and delves into the…

This paper investigates how bilingual Upper Sorbian-German teachers who belong to the Sorbian speech community (Lusatia, Germany) introduce the minority language during German language lessons in an Upper Sorbian school. In Lusatia, as well as in Sorbian schools, bilingualism is not of equal character; minority language speakers are all bilingual…

Constructing scientific explanations of natural phenomena is an important aim of science education. Explanation oriented science teaching approaches encourage learners to engage in sense-making discussions and construct the causal accounts of the phenomena under study. This article demonstrates a lesson-design model that guides biology teachers on…

This study examined the role of history education for nation building in Ethiopia, Germany Rwanda, South Africa, Switzerland, and USA using a comparative research method. Student textbooks and syllabi were the main data sources. Document review was the principal data-gathering tool and the data was analysed qualitatively. Findings revealed that…

This study examines the attitudes of German-speaking pupils towards Sorbian-language education and the problems these pupils indicate as an obstacle to becoming bilingual through educational settings. Based on the research carried out in the Upper Sorbian Grammar School in Bautzen/Budyšin (Germany) combining a statistical survey, in-depth…

In three experiments, learners used computerized learning material, which consisted of static pictures and on-screen text relating to the physiology of vision in one of two formats. The formats differed in method of access to text. Accessing text by clicking on picture components was hypothesized to produce superior learning to linear access…

This explorative, qualitative study examines the use and effectiveness of resources of multilinguality, with particular regard to the development of causal links in geography classes. Contentual and linguistic strategies of multilingual pupils in creating causal links were collected and evaluated systematically. This was done by means of a…

Children and adolescents spend a large part of their day at school. Physical and mental problems result from physical inactivity, sitting positions at work and "indoor lifestyle" (WHO 2004). Therefore, health education is a major topic in school. Biology classes (scholastic) can make an important contribution in this context. Health as a…

That the interplay of random and deterministic processes may result in both the limited predictability of nonlinear systems and the formation of structures seems to be a most valuable general insight into the nature of science. This study investigates the possibility of teaching and learning the interplay of chance and determinism in nonlinear…

Treating creationism as a controversial topic within the science and religion issue in the science classroom has been widely discussed in the recent literature. Some researchers have proposed that this topic is best addressed by focusing on sociocognitive conflict. To prepare new learning opportunities for this approach, it is necessary to know…

Worldwide, a tendency is visible in which upper secondary science curricula are innovated in the direction of context-based education. Crucial to these innovations is the way teachers interact with newly developed teaching materials and implement them in classroom practice. The focus of our research is to identify characteristics of the…

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 reports on the effects the use of a pocket calculator-based computer algebra system (CAS) has on the performance in mathematics of grade 11 students in Germany. A project started at 8 of about one hundred upper secondary schools in the federal state of Thuringia in 1999; 3 years later the former restrictions on the use of technology in…

Over the past 10 years, numerous empirical investigations of learning in physics have been carried out at the Institute of Physics Education (IPE) at the University of Bremen in Germany. The objectives of these investigations were: (1) to describe in detail individual learning processes; (2) to construct theoretical principles of individual…

This subunit on the history of Western Europe is part of one of four resource units for an eleventh grade area studies course. The subunit contains an introduction followed by a list of objectives dealing with generalizations, skills, and attitudes. A double-page format relates objectives, content, teaching procedures, and instructional materials.…
