Socioscientific issues (SSI) have been found to improve scientific literacy skills among K-12 students. Existing literature shows, however, that elementary preservice teachers are reluctant to implement SSI due to a lack of confidence with subject matter knowledge and knowledge of instruction concerning SSI. Previous research has focused on…

Science teachers' beliefs about teaching and learning are a vital component of teachers' professional competence and are often assumed to impact classroom practice. To date, these beliefs have been predominantly investigated regarding teaching and learning in general or for a particular science subject (e.g., physics). It remains to be determined…

Orchestrating inquiry-based science learning in the classroom is a complex undertaking. It requires fitting the culture of the classroom with the teacher's teaching and inquiry practices. To understand the interactions between these variables in relation to student learning, we conducted an investigation in two different classroom settings to…

Learning progressions, or representations of how student ideas develop in a domain, hold promise as tools to support teachers' formative assessment practices. The ideas represented in a learning progression might help teachers to identify and make inferences about evidence collected of student thinking, necessary precursors to modifying…

We examined curricular orientations that graduate students in science and mathematics fields held as they experienced urban high-school science and mathematics classrooms. We analyzed how these educators (called Fellows) saw themselves, students, teachers, schools, education, and the sense they made of mathematics and science education in urban,…

Reports an interpretive examination of four teachers' use of analogies to teach chemistry. Suggestions for how science teacher education can be informed by case studies of teaching in context, in this instance of analogy-inclusive teaching by four experienced chemistry teachers, are provided. (ZWH)

Examines the relationships among instructors' course goals, instructional activities, and students' assessment of their learning of content and writing in writing-intensive undergraduate natural and applied science courses. Finds that instructors are described along a continuum anchored by instructor-as-corrector on one end and…

Explores how the school classroom context influenced the expression of one prospective science teachers' beliefs about science and science teaching. Using the comparative method of data analysis, four interrelated categories of a student teacher's experience were generated: (1) beliefs about teaching science; (2) constrained teaching and…

Subjects (N=41) were randomly assigned to one of two groups defined by the teacher's clarity in a genetics lesson: low-clarity versus high-clarity. Subjects rated lesson presentation and completed a test on content. The high-clarity group perceived lessons as significantly clearer and achieved more than the low-clarity group. (DS)

The two-phase study was designed to (1) create a means whereby preservice teachers could lengthen the time they allow for a student to respond after posing a question; and (2) to study the relationship of want-time as an independent variable and dialogue measure, as a dependent variable. (RE)

The paper divides achievement in chemistry into five independent factors: cognitive, affective, problem solving, routine manipulative skills, and observational modes. The study explores the relationship between student performance in these areas and their responses to a Cognitive Preference Test in chemistry. (RE)

Investigates the influence of treatment and the interactions between treatments and selected pupil characteristic variables, with respect to pupil achievement and preference for treatment, and examines treatment-teacher interactions. Among the findings, this study suggests that students prefer to operate in less structured modes for the medium or…

Analyzes a study which examined the effects of teacher vagueness on comprehension of high school biology students (N=48) regarding the vascular system of angiosperms. Includes the finding that teacher vagueness terms significantly affect student achievement and student perception of lesson effectiveness. (CS)

Investigates the manner and the degree to which science teachers consider the nature of the subject matter in their decision making when they plan and deliver instructional tasks. Considerations for student development, curriculum guide objectives, and pressures of accountability dominated decision making. (Author/YP)

This study reports on a survey in Minnesota designed to provide a picture of the instructional styles that are used by seventh- and eighth-grade science teachers (n=139). Although relationships exist, it appears that seventh- and eighth-grade teachers are individualistic and diverse in their reported teaching technique preferences. (PR)
