Creating critical mass has become a cornerstorne of science policy on both national and transnational levels. It suggests that once a certain size is reached, exponential growth or accelerated change will occur. In reconstructing theories, policies and practices associated with critical mass, the paper traces the image of critical mass as a size…

The purpose of this study is to compare the instructional practices in science education in Malaysian and German secondary schools. Specifically, the objectives of this research are to seek answers for the following questions: (i) What are the current science teachers' instructional practices in German secondary school? (ii) What are the current…

General Studies (Sachunterricht) lesson, which includes social and science themes because of its interdisciplinary form, takes place in the curriculum of each class level at primary schools in Germany. The aim of this descriptive case study is to examine how the teaching process of third-grade General Studies lesson is run in terms of learning…

This paper presents a case study that investigated students' perceptions on the integration of a socio-scientific issue into a general chemistry course at a public university located in northwestern California. The teaching intervention is based on a digital learning environment structured by the software Prezi that students used to explore the…

This article discusses characteristics and forms of international collaborative research projects (ICRPs) and provides conceptual considerations as well as initial empirical insights on the impact of funding conditions on ICRPs in the social sciences and external project funding. Specifically, by presenting a German case study of funding formats…

Social media are a highly visible factor in the daily lives of our students. Why should teachers not take advantage of this and develop teaching and learning materials that use the designs found in such media to contextualise science learning? This article suggests some ideas for creating lab instructions using social media design as an innovative…

Practical work is an essential component of science education. However, insufficient approaches towards practical work can limit the potential it has for promoting both students' motivation and situational interest. One suggestion to solve this problem is to use alternative forms of lab instruction which are both motivating and easy to comprehend.…

Curriculum-assessment alignment is a well known foundation for good practice in educational assessment, for items' curricular validity purposes. Nowadays instruments are designed to measure pupils' competencies in one or more areas of competence. Sub-competence areas could be defined theoretically and statistical analysis of empirical data by…

Purpose: The paper discusses the camerawork within a historic video case study as a meaningful practice of visualization of classrooms and also as an aspect worth consideration in current contexts of video-based classroom research and teacher education. Design/methodology/approach: The case study combines elements of video hermeneutics and a…

Phosphates are essential components of any efficient fertilizer. Natural phosphate rock is, however, not available in every part of the world. According to the European Commission, phosphate rock has high economic importance as well as a certain supply risk--at least for Europe. For these reasons, environmental technology research has received a…

Explanatory typologies have recently experienced a renaissance as a research strategy for constructing and assessing causal explanations. However, both the new methodological works on explanatory typologies and the way such typologies have been used in practice have been affected by two shortcomings. First, no elaborate procedures for assessing…

The school context, like other influences, affects the development of students' epistemic beliefs (EBs), with theoretical conceptualizations suggesting a distinction between EBs related to professional and school science. However, empirical studies rarely address this distinction, and instruments separately assessing these EBs are not available.…

What learning opportunities in higher education promote the development of content knowledge (CK), pedagogical content knowledge (PCK), and pedagogical knowledge (PK)? In order to investigate this question, a cross-sectional study with a total of 274 German preservice biology teachers (21.5% male, average age 22.8 years) was conducted in German…

This article explores the influential role of planning on recognition-primed decision-making. Considerable prior thinking occurs and there is a need to trace and account for the cognitive processes that precede and guide decisions in dynamic outdoor environments. Seven expert leaders from four countries were interviewed about memorable decisions…

A case study of secondary experimental science instruction in Belgium demonstrates the importance of cross-national communication in the study of science education. Belgian secondary science education in the years 1880-1914 had a clear internationalist dimension. French and German influences turn out to have been essential, stimulated by the fact…
