A study was conducted at the College of DuPage in Illinois to find out if peer-teaching and the utilization of students as laboratory aids could improve class performance, personalize instruction, and benefit the student. Two classes of highly motivated comparative anatomy students and two classes of less motivated second semester general biology…

This paper is based on the idea that designing a knowledge representation for an intelligent physics computer tutoring system depends, in part, on the target behavior anticipated from the student. In addition, the document distinguishes between qualitative and quantitative competence in physics. These competencies are illustrated through questions…

Two studies were conducted to describe how students perform direct current (D-C) circuit problems. It was hypothesized that problem solving in the electricity domain depends largely on good visual processing of the circuit diagram and that this processing depends on the ability to recognize when two or more electrical components are in series or…

This paper identifies and analyzes the relationship between experiential science instruction, language arts, and cognitive development to provide information and recommendations concerning the integration of elementary science and language instruction. Annotated citations are provided grouped under the following categories: (1) recent status of…

Presented in this document are essays related to a research project focusing on conceptual obstacles which confine and inhibit scientific understanding (conceptual barriers). These include a short summary of research activities; research methodology; outline of a theory and summary of supporting evidence related to conceptual barriers encountered…

This document is designed to help integrate the skills of composing (writing) with the procedures and perspectives of New York elementary, secondary, and continuing science education programs. Sections are devoted to the composing process and its relationship to a science laboratory model, to techniques for evaluating writing, and to the spectrum…

Computer assisted instruction (CAI) provides active and non-linear instruction, but the microcomputer-videotape combination permits development of a broader range of instructional activities not previously possible with microcomputers alone. Instructional materials can be displayed alternately from the microcomputer or the videocassette…

This study investigated the implementation of a 7th grade biology curriculum ("Animal and its Environment") in Israel. The curriculum has seven parts, each one with a dictated sequence including well-defined objectives, suitable activities, and assigned materials, with little degree of freedom for the teacher. A primary concern for the…

Two experiments were conducted to characterize the system of beliefs that make up the naive impetus theory of motion and to determine what effects physics instruction has on students' conceptions of motion. Thirteen college students were asked to solve several quantitative problems and were interviewed about their answers in the first experiment.…

The tables, graphs, articles, and other sources of information in this document are designed to provide teachers with additional resources to supplement the unit "Motions and Collisions." The information is coordinated with the unit objectives specified in "Science 100, 101," the currently (1982) approved provincial guide for…

Data gathered from large-scale assessments in the Ontario Assessment Instrument Pool (OAIP) are examined. Implications for science instruction are to be found at the item level; the items should not involve more than two or three steps if the responses are to be informative. Items are collected and linked to provincial curriculum guidelines. These…

Current interest in the content and methodology of college physical science instruction stems from a recently adopted general education program for Montgomery College, a two-year comprehensive community college. It is contended that physical science should play a major and vital role within the science component requirements of a student's program…

A study of the use of four tutorials written in Cicero authoring language for a second level Open University course, "Biological Bases of Behaviour," focuses on why students do or do not use computer assisted learning (CAL) tutorials and students' and tutors' beliefs about the educational utility and practicality of CAL tutorials. Data…

This study investigated the contributions of the professional qualification of biology teachers, laboratory facilities, and biology textbooks to the teaching of biology in 10 government and 10 harambee schools in Kenya. Biology is currently a compulsory subject in all secondary schools in this country. Data were obtained from questionnaires…

Student variables which influence attainment of ecological concepts and conceptual systems were investigated. Researcher-designed paper/pencil and free-sort categorization tests were administered to 256 Science Curriculum Improvement Study (SCIS) students in grades 4-6. Findings are: (1) grade and ability, not sex, influenced concept attainment…
