Recent research has focused on innovative instructional shifts that aim to expand what constitutes science and engineering practices, exploring also how they can build on students' diverse language resources in science learning. However, few studies explore the intersections of elementary teacher preparation and the implementation of science and…

Apprenticeship and the associated support mechanism of scaffolding have received considerable interest by educational researchers as ways of inducting students into science. Most studies treat scaffolding as a one-way process, where the expert supports the development of the novice. However, if social processes generally and conversations…

Describes an experiment designed to compare different behaviors exhibited by second grade teachers and pupils using the Science - A Process Approach program to a comparison group of teachers and pupils. Includes and analysis of 12 teacher and 10 student behavioral factors. (PR)

The time between asking a question and accepting an answer or proceeding with the lesson is reported for five lessons for four instructors. There was little change during four weeks of instructor-supervisor conferences intended to alter questioning techniques. (AL)

Using interaction analysis, studied the classroom verbal interactions of three types of elementary science classes: not using a process-promoting curriculum; using a process-promoting curriculum, with or without a consultant. Among the findings was that teachers who interacted with a consultant were more indirect in their teaching. (MLH)

Reports results of a study of biology classes in Israel that includes describing transactions in a representative sample of biology classes (N=22) in the year 1973, comparing transactions in recitation with those of laboratory lessons, and studying the effects of subject matter on the classroom transaction. (CS)

Describes a study which measured perceptions of classroom behavior, both perceived and ideal, of science teachers and students. Using an interaction analysis system to analyze the actual classroom behavior in 33 junior high school science classes, the authors conclude that the teachers perceived their classes to be more inquiry oriented than the…

Engagement has been viewed as an important construct to understand students' learning performances in classroom settings. Taking an interactive perspective, the study investigates ninth graders' cognitive, emotional, and behavioral engagement in teacher-centered (TC) and student-centered (SC) technology-enhanced classrooms. 54 students from two…

Research on the relationship between teaching strategies and student outcomes supports the use of inductive/indirect teaching strategies. Research shows that this can be achieved through the analysis of model lessons with a systematic observation instrument. (MLH)

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…
