Investigated use of overhead transparencies containing a sequence of diagrams to represent a three-dimensional structure at different stages during a rotation. Significant learning occurred among 120 Bahraini boys (aged 15-16) when the transparencies contained multi-colored diagrams which were exposed simultaneously or individually in a cumulative…

Evaluated effectiveness of six instructional programs (each dealing with a different aspect of a spatial task related to diagrams of three-dimensional structures) with Bahraini students (ages 13- to 17-years-old). All brought about a significant degree of learning over all age groups. Implications of these and other findings are discussed.…

Investigated the self-esteem of physics teachers of students taking pre-service physics teacher education courses. Findings indicate that students who dropped out from the courses had lower self-esteem than either students who satisfactorily completed them or similarly qualified students who did not take the courses. Implications for teacher…

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…

Studied a limited number of students exposed to teaching materials and strategies (developed from a cognitive perspective on learning), such that their impact would be monitored to determine how the learners constructed new knowledge frameworks as teaching proceeded. Includes background information, comparisons of teacher's intentions and…

Reports a classification of expository teaching styles of biology, chemistry and integrated science teachers in Nigeria. No evidence was found of pupil-pupil interaction in any of the lessons observed. Compares results with other studies from Britain, Canada, and Indonesia and indicates significant differences. (CW)

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 of the relationships between the component skills involved in practical work assessment. Skills assessed included observing, manipulating, planning, interpreting, reporting, and self-reliance. The literature relating to inter-skill relationships is reviewed. (CW)

Describes a study that was designed to apply the learning hierarchy paradigm in an instructional unit in high school biology. Findings indicated that regardless of the pupils' sex or the type of school, students taught the hierarchically organized learning task achieved significantly higher than students whose learning task was not hierarchically…

Presents a method for representing students' knowledge about basic scientific concepts by classifying ideas produced in a free-writing task. Implies that those differences which exist can best be attributed to general fluency in the language of instruction rather than factors that are specific to the learning of science. (Author/CW)

Reported is a case study of science teaching in middle and upper primary school classes. The background of the schools, teachers and students, classroom observations and classroom environment are described. Exemplary classes were materials-centered and encouraged formulation and testing of predictions. Other characteristics are listed. (CW)

Presents a theoretical framework for and a detaled description of a model for teaching scientific analogies. The framework focuses on the definition of an analogy, analogical learning, variables related to analogical learning, evaluating outcomes of analogical limiting, and limitations of using analogies in teaching. (JN)

Investigated the efficacy of an instructional program designed to induce students to construct a mental scheme in which experimental design and natural experiments are understood as facets of the same problems and which incorporates a general solution procedure applicable to both. Results show a highly significant posttest achievement by the…

Examined students' conceptions of the words "force" and "energy" using the interview-about-instances approach. Implications for science instruction and instructional strategies are discussed based on findings that many students have views of these concepts that are different from accepted scientific views. (JN)

In this study, students' achievement using three individualized audiotutorial (IAT) biology learning units was investigated. The method of instruction, gender, academic achievement in mathematics and biology, and students' IQ levels were compared. (KR)
