Little is known about how the content of a video case influences what preservice teachers learn about science teaching. This study was designed to determine the impact of two different video cases on preservice elementary teachers' conceptions of multiple aspects of effective science teaching, with one video selected to focus attention on the role…

Teachers often have difficulty implementing inquiry-based activities, leading to the arousal of negative emotions. In this multicase study of beginning physics teachers in Australia, we were interested in the extent to which their expectations were realized and how their classroom experiences while implementing extended experimental investigations…

Using the biology faculty of one high school (n = 9) and the mathematics faculty of another (n = 16), this study tested the hypothesis that constructivist teachers play an active role within teacher communication networks (the constructivist-teacher hypothesis). This hypothesis contrasts with the view that constructivist teachers operate alone and…

Determines the effect on inquiry of different contingencies of reinforcement. Classes of biology students were exposed to one of four treatments: verbal reinforcement and mimicry; using student ideas as reinforcers; using special privileges as reinforcers; and no reinforcement. Results include verifications that verbal reinforcement and mimicry…

Two teacher behavior patterns differing in the degree of directiveness utilized by the teacher were investigated. The results show that teacher behavior does effect student behavior in elementary science classes where hands on activities are employed and presents evidence that materials, activities, and curricula cannot be made teacher-proof. (BT)

Examined management behaviors of junior high science teachers (N=16) and the relationship to task involvement of students operating in small group laboratory settings. Results of 91 observations indicate that teacher behavior was directed in three ways: whole class, small groups, and nonclass related. Implications for science instruction are…

Examines the development and usefulness of the Elementary Science Teachers' Preferences (ESTP) test. Findings suggest that this instrument is useful and valid in determining differences between teaching preferences of teacher-centered and student-centered teachers. Findings also indicate that polarized labeling of teachers is inappropriate. (MA)

All three teachers studied had similar planning and postlesson reflections for teaching classes in which they were and were not certified. However, when teaching some classes in which they were not certified, some of their behaviors resembled those of novice teachers. (PR)

Studies the effects of student-structured (SSLS) and teacher-structured (TSLS) teaching strategies. SSLS students consistently exhibited lower frequencies of teacher dependency behaviors than TSLS students. Need affiliation results varied with the grade level of students. (MA)

Investigated were the seating patterns of target students in science classrooms to see whether there was an action zone or T zone present. Questioning level, understanding level of students, and pacing of instruction by teachers are discussed in terms of target students. (KR)

Describes the effects of teacher subject-matter knowledge on classroom discourse at the level of individual utterances. Details analyses conducted in a year-long study of language in the classrooms of four new biology teachers. Among the findings are that these teachers talked more, asked more questions, and relied heavily on low cognitive level…

Examined relationships between teaching behaviors and student engagement in 13 middle school science classes. Results indicated that seven managerial variables and four instructional variables were significantly related to student engagement rates. Types of tasks allocated by teachers were also significantly related to types of tasks undertaken by…

Presents a qualitative analysis of an episode from a beginning teacher's biology lesson to demonstrate the intricate relationships among teacher intentions, curriculum materials, teaching, and potential student outcomes. Develops the concept "epistemological flatness" as a way of characterizing salient aspects of curriculum materials and…

Reports on a study designed to assess the kinds of learning opportunities students had as they dealt with science content and the problems teachers faced in managing different kinds of assignments. Management strategies associated with these assignments are described and the effects of these strategies are considered. (Author/TW)
