Describes the philosophy, development, content structure, and general instructional strategy of BioCom, an introductory biology curriculum for the heterogeneously mixed high school science classroom. Discusses recent recommendations by national commissions and science education research and similarities and differences between BioCom and ChemCom.…

Describes a study designed to differentiate between universal and culturally specific aspects of children's biological understanding. A group of 363 kindergartners, second graders, and fourth graders from Israel, Japan, and the United States matched 16 attributes to people, animals, plants, and inanimate objects. Results revealed how cultural…

Using science from the classroom, a teacher involves students in variety of explorations to identify safe foods from outdoors. These activities culminate in a Wild Plant and Beast Feast day, where the students have an opportunity to share their new cuisine and recipes with classmates and teachers. Tips on the successful development and…

Using socks with colored bands, a teacher makes mitosis and meiosis fun and meaningful for students. Asserts that during extension activities students used the aforementioned exercise as a springboard to better understand the phases of the cell cycle of Allium root tips, whitefish blastula, and Lillium anthers. (ZWH)

Examines three anecdotal cases of the teaching of evolution theory in an exploration of the best approaches for teaching about evolution. Three instructional options are presented: (1) readings in natural history, (2) commercially prepared activities, and (3) the use of small-group (peer) discussions. (LZ)

Discusses exemplary teacher and student characteristics that can provide the base to generate an Intelligent Computer Assisted Instruction (ICAI) shell. Outlines the expertise, learning, student-model, and inference modules of an ICAI shell. Describes the development of an ICAI shell for an undergraduate course in human physiology. (33 references)…

Describes a high school biology assignment that had students read a self-selected book where the main character experiences nature and is changed by it. Evaluation was based on journal entries and a formal paper. Seventy percent of the students indicated they greatly enjoyed the assignment. (PR)

Reports a study that examined the generalizability of selective-attention and academic-studying hypotheses to a modified science chart medium. The adjunct questions used in this study were designed to selectively focus students' attention on specific columns in a modified science chart, with the goal of improving student achievement on a test…

Article discusses the Science-Technology-Society approach and describes a study (n=116) of differences in learning outcomes for Taiwanese students who study college biology in an issue-oriented format with students who study in a concept-oriented format. Students in the issue-oriented format class had statistically higher scores for concept…

Presented are 13 concepts considered important in estuarine education. These concepts were chosen by a panel of professionals in estuarine education, research and management. Included are the study methods, results, and implications for science education. (KR)

Scrutinizes the assessment of students' practical skills, in an honors-level biology examination, for construct validity utilizing both correlational and factor analytical methods to explore relationships between students' practical (laboratory) and theoretical (written) performances. Indicates that teacher assessment of practical skills resulted…

The population of Gyrinus, the whirligig beetle, is assessed using the Lincoln mark-recapture index. This technique has the advantage of helping the student to understand simple proportion as well as other concepts. (Author)

The cognitive factors that contribute to competence in the biological sciences were examined. The role played by cognitive style and analytical ability is discussed. The ability to abstract relevant information, evaluate it, and use it is affected by the skills of analysis and cognitive style. (KR)

Describes methodology for a fresh water life study with elementary through college age students with suggestions for proper equipment, useful guides, and other materials. Proposes an activity for the collection and study of plankton. Includes background information.(MCO)
