Task orientation is currently a prominent concept under discussion in primary school didactics. It focuses on tasks along which pupils acquire competences on distinct levels of competence. The qualitative empirical study TAPSE (Textbook Analysis in Primary Science Education) pursues the question which conception of task orientation is present in…

This study assessed the (i) ways in which, and extent to which, several aspects of nature of science (NOS) are represented in high school biology and physics textbooks in the United States (U.S.); (ii) extent to which these representations have changed over the course of several decades; and (iii) relative impact of discipline, and textbook…

Recent calls for reform in education recommend science curricula to be based on central ideas instead of a larger number of topics and for alignment between current scientific research and curricula. Because alignment is rarely studied, especially for central ideas, we developed a methodology to discover the extent of alignment between primary…

This study aims to identify students' misconceptions regarding covalent bonds. Seventy-seven graduate students in the middle of Indonesia participated in the study. Data were collected in three stages. First, misconceptions were identified by using the Semi Open Diagnostic Test. Ten students who experienced the worst misconceptions were…

Interviews with representatives of nine municipal agencies involved in air-quality education were analyzed for concepts and skills perceived as important for citizens in addressing air-quality concerns. Interviewees focused mainly on general air quality-related understandings (60.2%), although cognitive skills (22.0%) and specific concepts (17.8%)…

This study investigated the representations of a select group of scientists (n = 10) in a sample of Canadian high school and college textbooks. Drawing on semiotic and cultural-historical activity theoretical frameworks, we conducted two analyses. A coarse-grained, quantitative analysis of the prevalence and structure of these representations…

Photographs are a major aspect of high school science textbooks, which dominate classroom approaches to teaching and learning. It is thus surprising that the function of photographs and their relation to captions and texts have not been the topic of analysis. The purpose of this study was to investigate the prevalence, function, and structure of…

The presentation of gas properties in terms of the qualitative-quantitative mode and gas law sequence is examined by analysis of 14 chemistry textbooks used in Australia and on questionnaires concerning teaching approaches by 104 teachers. Findings indicate that teaching involves minimal use of qualitative relationships of the gas laws and…

Linguistic content analysis, method of encoding textual data by categorizing key words and identifying relationships, was developed to assess degree to which science was portrayed as process of inquiry within high school biology textbook series. The frequency of science as a process of inquiry increased from 1956 to 1965, then showed a pattern of…

The objectives of this study are: (a) elaboration of a history and philosophy of science (HPS) framework based on a reconstruction of the development of the periodic table; (b) formulation of seven criteria based on the framework; and (c) evaluation of 57 freshman college-level general chemistry textbooks with respect to the presentation of the…

Reports results on an analysis of five seventh grade life science textbooks for sexist language, images, and curricular content. Authors conclude that sexist language and images exist in these textbooks. The content of all of the books contained a relatively low level of integration of achievements of women scientists and a lack of information…
