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…

Multilingual youth, from nondominant communities, are often denied critical opportunities for engagement in robust sensemaking due to deficit-based perspectives and linguistic hierarchies. To advance equity, it is important to recognize all youth as epistemic agents and facilitate opportunities to take on intellectual positions. Drawing on…

Recent reforms in K-12 science education call for curricular materials that are designed to be "coherent for students." This form of coherence arises when the classroom community sees their science work as addressing their questions and problems. In enactment, the teacher sometimes has to improvise from the planned trajectory of the…

The present study investigated the guidance provided by science teachers to resolve conflicts during socioscientific issue-based argumentation activities. A graphical representation (GR) was developed as a tool to code and analyze the dialogue interaction process. Through the GR and qualitative analysis, we identified three types of dialogue…

While a body of research exists on individual metacognition, research on reflective communities is just beginning. This study generated a framework for conceptualizing metacognition in groups by describing likely components of group metacognition. I focused on a group of five preservice science teachers engaged in problem-based learning (PBL). The…

This paper analyses the use of various communication channels in science teachers' professional development project aiming to develop versatile uses for ICT (Information and Communication Technologies) in science teaching. A teacher network was created specifically for this project, and the researchers facilitated three forms of communication…

Nineteen beginning preservice science teachers were randomly assigned to one of the following treatments given in the first two weeks of the semester: a) training in interaction analysis (a modification of Hall's instrument for the analysis of science teaching; b) training in conducting and interpreting Piaget-type interviews; and c) a control…

The purpose of this study was to develop and test a classroom observation system for use in training and supervising secondary school science student teachers. The instrument, the Science Interaction System (SIS), has 31 categories covering both affective and cognitive teacher behaviors. Thirteen student teachers were randomly assigned to an…

In this study a partially-developed category system was modified, and a set of categories was established for describing content instruction used in the classroom by Physical Science Study Committee (PSSC) and non-PSSC physics teachers. Seven physics teachers in the first phase of the study were videotaped to develop the instrument for recording…

Case study recordings of a science lesson are assessed to examine the role of talk in the learning process. Implications are raised for similar informal assessments by practicing teachers. (Author)

Study was conducted to explore patterns of verbal interaction in science classrooms. Pupil characteristics were measured in the beginning and towards the end of instructional term. Four patterns of outcomes, communication, and pupil characteristics were found. These are named as success, rejection dependency, person orientation and alienation…

The Instrument for the Analysis of Science Teaching was used to evaluate verbal behavior of teacher trainees instructing pairs of students in each of two science concepts. The greatest differences in teacher behavior was due to differences between students, not differences in science content. (AL)

Analyzed were behaviors of secondary school science student teachers and their cooperating teachers. Objectives were (1) to provide data on teacher behavior by describing aspects of teacher-pupil verbal interaction, (2) to identify non-random changes in verbal behaviors of the student teacher, (3) to relate these changes to the verbal behaviors of…

Reported is a study to determine changes in classroom verbal behaviors of 23 student teachers in secondary science and the relationship of the behaviors of their respective cooperating teachers to these changes. The investigator attempted to identify the relationship between perception of the student teacher by the science students and the…

The purposes of this study were to: (1) design a usable and valid modern verbal interaction analysis instrument and (2) to explore the verbalization taking place in selected ninth-grade physical science classrooms by utilizing the Modern Science Interaction Instrument (MSII). Two groups of ninth-grade physical science teachers participated. One of…
