The intended, perceived, implemented, and achieved curriculum of high school biology classes in Israel was studied using a variety of data sources and research methodologies. The intended curriculum was identified by analysis of commonly used laboratory manuals. The perceived curriculum was captured by procuring the views of teachers and students…

Discusses responses to student questionnaires used to identify the effect of instructional strategies on study practices and attitudes towards biology. Concludes that while organized teaching has a stronger effect on study skills, teaching by enquiry has a stronger effect on curiosity and interest. (Author/CW)

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…

Describes changes and effects of the Israeli paper-and-pencil matriculation examination in biology since first analysis in 1972. The examination has been significant for implementing an inquiry-oriented high school biology program based on the Biological Sciences Curriculum Study. Implications for upgrading science education are discussed.…

Describes the rationale and activities developed and tested by the Biology Critical Thinking project (BCT). Presents the project guidelines for developing activities, a list of skills selected as goals of BCT, instruments used in determining effectiveness of the activities, results of the pilot study, and a sample activity involving vitamins.

Described is a study of 147 students that indicated a high proportion of students did not understand the concept of limiting factors. Textbook presentations that create problems are discussed. Strategies which may be more effective in teaching the concept are suggested. (CW)

Proposes an approach to school laboratory experiences which leads to gradual acquisition of inquiry skills based on the idea of advance organizers. Presents a design which is context familiar and can serve as an introduction to scientific inquiry. Discusses student achievement, and teacher and student attitudes. (CW)

A great number of misconceptions in diverse subject areas as well as across age levels have been documented and described. Photosynthesis is one of the more intensively studied areas in biology. The purpose of this research was to carefully select and define misconceptions about photosynthesis needing remedial efforts. To achieve this, a specially…

Science/Technology/Society STS) has been defined as teaching and learning in the context of human experiences. The STS movement has grown out of dissatisfaction with the curriculum reform of the 1960s and utilizes a problem solving approach that appeals to students' interests. This paper describes the STS approach and reports research results…

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.…
