Tairab, Hassan H.; Wilkinson, William J. – Research in Science and Technological Education, 1991
The degree of agreement between evaluations of trainee biology teachers using students' perceptions of teacher skills and characteristics obtained from Science Student Perception Questionnaire (SSPQ) and evaluations of these same teachers by their university supervisor and their school supervisors was determined. Results indicate an agreement and…

Pickersgill, Stephen; Lock, Roger – Research in Science and Technological Education, 1991
Student understanding of 30 nontechnical words used in science was investigated. No significant differences were found between the understanding of nontechnical words in science or between the verbal reasoning ability of males (n=108) and females (n=89). Of the four different question formats, students had the most difficulty with the synonym…

Cross, R. T.; Pitkethly, A. – Research in Science and Technological Education, 1991
Research suggests that many children have a concept of speed which is counterproductive to sound road crossing decisions. An attempt at conceptual change through the teaching of a unit on speed to grade one children is described. There is optimism that six- to seven-year-old children can apply classroom experiences to real life situations. (Author)

McElwee, Paul – Research in Science and Technological Education, 1991
Concepts used by two classes of grade eight students, one advanced and the other average, to explain the changes that occur when water is heated to boiling are presented. Little difference was found between groups in terms of the personal misconceptions used to explain boiling. The changes that take place in conceptual knowledge immediately after…

Johnston, Kate; Scott, Philip – Research in Science and Technological Education, 1991
An intervention study with 12- to 13-year-old students which attempts to move students' thinking about matter and the dissolving process toward the school science view by use of activities and group discussion tasks which directly address some of the thinking underlying students' prior ideas is described. Students responses to the strategies…

Relan, Anju – Research in Science and Technological Education, 1991
The effects of a visual advance organizer on a biology concept learning task among fifth graders (n=48) was investigated. After exposure to the advance organizer, three levels of learning outcomes-knowledge, comprehension, and application-were evaluated. Findings of the study are discussed in terms of the assimilation theory, aptitude-treatment…

Boyes, E.; Stanisstreet, M. – Research in Science and Technological Education, 1991
Combined free response questionnaire and interview procedure are used to probe students' ideas regarding how they believe they see both luminous and nonluminous objects and how they think they hear source of sound. From large sample of students studied (n=1901), prevalence of ideas in different age groups is compared, and progression can be seen.…

Taber, Keith S. – Research in Science and Technological Education, 1991
Students in their first weeks of secondary school were asked to select from a list those topics they would be interested in studying in science. Gender differences were found in that boys predominately selected topics with a mechanical connection, whereas girls predominantly selected topics related to human biology. (Author)

Jungwirth, Ehud – Research in Science and Technological Education, 1990
Discussed is whether, and to what extent, science teachers critically and spontaneously attend to the logical structure of situations, and whether they need prompting, or completely fail to do so. The relationship between the results of this study and science teachers' pre- and in-service education is discussed. (Author/KR)

Monk, Martin – Research in Science and Technological Education, 1990
This study reports a new analysis of data on children's ideas about direct current (DC) electrical circuits. The analysis is theoretically informed by Piagetian stage theory of genetic epistemology. The limits of the genetic epistemology are discussed. (KR)

Tamir, Pinchas; Gardner, Paul – Research in Science and Technological Education, 1989
The purpose of this study was to identify interest patterns related to high school biology. Eight task dimensions were established before testing. Findings include: the highest interest was in human biology topics and students whose parents' employment was science related showed higher interest in biology. (CW)

Happs, John C.; Stead, Keith – Research in Science and Technological Education, 1989
Considered are two commonly used techniques, the interview and word association techniques. Highlighted is a third technique called the repertory grid. This third technique can be used to interpret students' knowledge based on an explicit, psychological theory of human behavior. (Author/CW)
