The increasing attention in science education reform documents to language and literacy, coupled with the growing linguistic diversity of United States classrooms, means that science teacher educators and researchers are facing an important task of preparing secondary science preservice teachers (PSTs) to teach a language- and literacy-integrated…

One goal of project-based science is to promote the development of scientific discourse communities in classrooms. Holding rich high school scientific discussions is challenging, especially when the demands of content and norms of high school science pose challenges to their enactment. There is little research on how high school teachers enact…

Two disparate research programs have addressed the challenge of instructional multimedia design. One, based on cognitive load theory, has focused on ways of reducing unnecessary cognitive load during instruction to free up resources for learning. The other, based on constructivism, has centered on interactive multimedia, allowing students to build…

The article grapples with the question of how much curriculum change is appropriate in a given context and in a given time frame. How can a balance be struck between stagnation, on the one hand, and the promotion of unrealistic innovation on the other? In answer to this dilemma, the concept of a zone of feasible innovation (ZFI) is proposed and…

The practical epistemology used by students and the epistemological moves delivered by teachers in conversations with students are analyzed in order to understand how teaching activities interplay with the "how" and the "what" of students' learning. The purpose is to develop an approach for analyzing the process of privileging…

Discusses insightful learning, trace system,'' and laws of perception and Pragnanz in connection with problem solving and critical thinking in science teaching. Suggests 19 guidelines for sequencing curriculum and identifying activities for use in science classes. (CC)

Addresses the importance of recognizing the prior knowledge and misconceptions of science educators. Provides perspectives on the nature of knowledge, conceptions of learning, nature of science and of teaching, and the relationship between general principles of learning and teaching. (ML)

Presents a general theory of instruction which suggests that the teacher's function is to create a new environment in which effective instructed learning occurs. Illustrations for this theory with reference to science instruction and a review of prior statements identifiable as theory are also included. (HM)

Reviews four hypotheses about learning: Comenius's transmission-reception theory, information processing theory, Gestalt theory, and Piagetian theory. Uses the categories preunderstanding, conceptual change, and learning processes to classify and assess investigations on learning processes. (PR)

Describes an interim program which stresses pre- and in-service teacher cooperation in constructing instructional modules according to university determined competency model prior to actual student teaching. Indicates acquisition of advantages by both experienced and prospective teachers through interactions with school students. (CC)

Describes a case study of an experienced provocateur-teacher in which the teacher's theory for science learning and teaching during teacher-student interactions was inferred from classroom observations, teacher-student discourse, and stimulated recall interviews. The teacher's instructional moves were interrelated with the components of his…

Tested Ausubel/Novak hypothesis that primary grade students can learn meaningfully certain aspects of science concepts in the "reception learning" model. Revised audio-tutorial instruction unit on earth based on understanding children's misconceptions; assessed impact of revised units with second graders; and compared results to concept…

Addresses the power held by persons who construct curricula, teach, and do research from a frame of reference that includes definite purposes for and theories about science education. Suggests the purpose of science education as a discipline is to improve existing procedures and establish new and verified procedures for teaching science.…
