Blum, Abraham – Science Education, 1982
If students are expected to become interested in science as a career or hobby, they must perceive their science courses as being useful. Student perceptions of usefulness of curricula were investigated relative to two agricultural programs taught in Israeli elementary and junior high schools. (PB)

Nimmer, Donald N. – Science Education, 1982
Reviews the science portion of five standardized achievement test batteries, stating these tests are insensitive to the assessment of curriculum changes in earth science. Contends an accurate assessment of a curriculum's effectiveness is possible only through the use of evaluation techniques and instrumentation keyed to the curriculum's specific…

Dillashaw, F. Gerald; Yeany, Russell H. – Science Education, 1982
Use of the Teaching Strategies Observation Differential (TSOD), a 10-category system for observing and classifying teacher classroom behavior, is discussed as it relates to training preservice elementary school science teachers. Contends that skill in the use of TSOD helps preservice teachers become more effective in bringing about desired pupil…

Lawson, Anton E. – Science Education, 1982
Many science curriculum development projects have the goal of increasing students' ability to employ scientific or formal reasoning strategies. Argues that longitudinal data of students who acquired formal reasoning strategies as a consequence of specific instruction are needed to provide evidence that these skills will help in other academic…

Posner, George J.; And Others – Science Education, 1982
A general model of conceptual change which is largely derived from current philosophy of science, but which can illuminate learning as well, is described. Some features of this model are illustrated by interviews with students studying special relativity in physics. Finally, some pedagogical implications are presented. (Author/PB)
