The purpose of this investigation was to evaluate the effectiveness of six instructional programs with the aim of alleviating the problems encountered by students in visualizing rotation in molecular diagrams. Models were filmed rotating around the three different axes with different speeds with and without shadows. (KR)

Described is a collaborative study between a Year 11 physics teacher and 3 university personnel designed to identify and document the manner in which content knowledge was transmitted in the classroom by the teacher and how this knowledge was acquired by students. The role of the textbook is discussed. (KR)

Reported is a study in which secondary school students assessed their teachers for characteristics of effective science teaching. It was shown that the instrument used was highly valid and reliable and that secondary school students could effectively assess their teachers' pre-classroom characteristics, teaching behaviors, personality, and…

The purpose of this study was to determine the socio-cultural factors which mitigate against the learning and teaching of science in the secondary school. It was found that authoritarianism, goal structure, the African world-view, societal expectation, and sacredness of science have significant effects on the learning of science. (CW)

The purpose of this study is to elaborate the issue of exemplary teaching in chemistry in the context of a centralized educational system, in which chemistry curriculum development and implementation are also centrally controlled. Students' perceptions of the learning environment were also investigated. (KR)

Presented is an analysis of 40 research studies which compared the achievement in science and the attitudes of Israeli male and female students toward science and science learning. Grades covered include 5-12. A list of 55 references is included. (CW)

Six types of remedial projection slide programs were tested on male students (n=120) who showed difficulty in visualizing rotation from molecular diagrams. There were no significant differences in improvement of understanding which were dependent on the number of remedial diagrams. However, when slides contained multicolored diagrams, which were…

The relationships and possible effects of various personal home and school variables on the acquisition of functional biological, chemical, and physical scientific knowledge by tenth grade Israeli students (n=544) was investigated. Biology was the only subject in which functional knowledge was significantly related to nonformal science activities.…
