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…

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…

Studied the similarity of the astronomy portion in five science textbooks at the fourth through sixth grade levels by comparing students' responses to text authors' requirements. Concluded that the texts had more in common across grade levels than within grade levels. (CC)

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…

Reports on a study designed to examine selected units of commonly used elementary science texts, using the Project Synthesis goal clusters as a framework for part of the examination. The discussion of the finding focuses on the comparison of the results to recommendations of the National Science Teachers Association (NSTA). (TW)

Reports on a study to determine the effects of the presentation of questions inserted into texts for students in introductory biology. Results indicated that students reading the text with questions at the beginning of the paragraph scored significantly higher on achievement tests than the students reading without questions. (TW)

Reports on a study designed to determine the influence of resequencing general science content on sixth grade students' science achievement, attitudes toward science, and interest in science. Results suggest that students experiencing the resequencing exhibited significantly higher science achievement, more positive attitudes toward science and a…
