Examines college students' perception of an interactive videodisc learning system as an alternative to the conventional laboratory for learning biology skills and concepts taught under classroom laboratory conditions. Reports that the videodisc instruction gave more experimental and procedural options and more efficient use of time than the…

Determines how the use of a science education program affected selected ninth-grade students' comprehension of science reading material. The different effects of the program depended on students' reading and mathematics scores. (Author/YP)

This study examined the impact of a biology course emphasizing computer simulation on student achievement and student attitudes toward science. The students in the experimental group were placed in a class limited to 16 students to have 2 students to each computer. (YP)

To promote large-scale science education reform, developers must create innovations that teachers can use to learn and enact new practices. As part of an urban systemic reform effort, science materials were designed to reflect desired reforms and to support teacher thinking by addressing necessary content, pedagogy, and pedagogical content…

Investigated were the effects of interactive computer-generated homework on unit tests, a final examination, and a comprehensive test given near the end of a Physical Science I course. The results indicated that the use of the homework reduced the effectiveness of the American College Test scores as a predictor of course achievement. (YP)

Teaching strategies associated with a conceptual change model of science teaching were examined in a study of seventh-grade life science teachers (n=13). Greater use of conceptual change teaching strategies was associated with use of the special instructional materials, not with the training. Students in classes where teachers were provided with…

Presents a qualitative analysis of an episode from a beginning teacher's biology lesson to demonstrate the intricate relationships among teacher intentions, curriculum materials, teaching, and potential student outcomes. Develops the concept "epistemological flatness" as a way of characterizing salient aspects of curriculum materials and…

Learning using primary literature may be a way of developing a capacity for scientific ways of thinking among students. Since reading research articles is a difficult task for novices, we examined the possible benefits of learning using primary literature versus secondary literature, particularly with respect to their influence on the creation and…
