Although results of both formative and summative evaluation can be used for planning the next generation of a curriculum, a need exists for a third kind of evaluation, namely, Pre-Planning Evaluation (PPE). The purpose of PPE is to provide a database to curriculum development deliberations to assist in decision-making and to guard against neglect…

Rationale for and example of a strategy to overcome reading difficulties are described. Before reading a bio-technical text, students read a story (sample included) in which the same biological and technical terms are used, but in a more familiar context and style. (Author/JN)

Describes and evaluates one assignment from a unit designed to teach basic science concepts and instructional strategies to primary school teachers, specifically, the control of variables. (SK)

Evaluation of an elementary level science curriculum unit (MATAL) illustrates intensive evaluation. This method involves classroom observation by trained observers, formulation of course objectives, student interviews (ability tests), and lesson planning. It stresses the identification of learning difficulties which hinder attainment of course…

In this study, the attitudes of Israeli children aged 6 to 15 years were surveyed regarding their conceptions of plants as living things. It was desired to find out whether children consider plants to be alive, the knowledge differences between the different age groups in the study, how children classify plants according to biological criteria and…

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)

Examined is the relative status of school variables versus home variables to explain the variance in science achievement. The contribution of school variables was found to be both subject specific--larger in subjects taught in school and less dependent on general ability, and system specific--larger in low socioeconomic schools. (Author/CW)

Investigates Israeli students' (grades four through nine) knowledge regarding the concept of a "gas" prior to and following instruction. Reports that students do not spontaneously develop a general idea of gas prior to instruction, and only after instruction do they first acquire this knowledge. Suggests three implications for…

Israeli children's (kindergarten to grade nine) explanations about the water cycle are described. Reports the children's views about the source of clouds and the mechanism of rainfall. It was concluded that understanding evaporation is a necessary condition for explaining a mechanism of rain containing the ideas of condensation and heaviness. (YP)

There is little doubt that the findings of research in science education can be depressing at times. The literature is replete with reports and research findings which highlight problems and shortcomings associated with the teaching and learning of science. In order to provide a refreshing alternative to the majority of research reports which…

Discusses in general terms the approaches necessary for effective dissemination and implementation of an educational program in a country and then relates these approaches to the cooperative relationship between the University of California at Berkeley and the Israel Science Teaching Center's MATAL and PELE Projects. (CS)

This study (n=192) examined the use of analogical instruction to overcome misconceptions about conservation of matter. Students who understood the concept conservation of matter when iodine was evaporated were able to transfer their understanding to the evaporation of acetone. This indicates that teaching by analogy can be an effective tool in…

Examined grades 6-12 students' (N=2000) preferences and choices regarding science subjects and relationships of these preferences to school type, age, and sex. Findings indicate that zoology and human anatomy/physiology were most preferred while ecology was least preferred. These and other findings are related to a previous study conducted in…

Investigates whether elementary children can compare forces by comparing numbers of weights used in spring and balance problems. Reports that children did not identify weight and force, but they were able to use the ratio between the numbers of weights to compare forces. Suggests some instructional methods based on the findings. (YP)

Investigated whether preservice elementary teachers in Argentina and Israel held scientific views that enabled them to correctly nstruct their future students to achieve a concept of energy, noting differences between the scientific concepts of students in the two countries. Questionnaire data indicated that students were very similar, but their…
