Discusses the cognitive outcomes of physics laboratory exercises and suggests three types of experiments which should be added to those normally used in physics courses. (HM)

Describes a research and development project aiming to help develop secondary students' abilities to understand biotechnology/genetic engineering. Focuses on an exemplary true-to-life experiment, planned and executed by students in grade 8, that involves external experts and uses an industrial research laboratory for solving genuine questions.…

Investigated the interaction between science teaching strategy (semideductive, structured inductive, hypotheticodeductive) and selected learner characteristics (Piagetian cognitive level and field independence) in terms of student achievement in science. Achievement of undergraduate elementary education majors (N=77) in a general science program…

Volume 8, No. 2 of Investigations in Science Education contains critiques of articles dealing with science education research about various aspects of instruction. Also included are five responses from authors of articles to critiques of their work as it has been reported in professional journals. In total, this volume contains 10 critiques and…

The purpose of this experiment was to compare an inquiry-oriented Biological Sciences Curriculum Study (BSCS) style laboratory approach with a more directive traditional approach on student outcomes in the cognitive and affective domains of learning at two private, midwestern liberal arts colleges. Intact laboratory sections of students enrolled…

Describes three perspectives from which middle school teachers can plan laboratory activities for the purpose of improving students' scientific literacy. Perspectives are the learning cycle approach categorizing activities by stages of development; problem-solving skills approach categorizing activities according to the amount of teacher control;…

This paper discussed the use of structured observations as a research strategy in two recently completed studies that investigated students thought processes and behaviors in a microcomputer-based laboratory (MBL) environment and in other instrument-based laboratory environments. In the first study, students' behaviors and thought processes were…
