Preservice preparation courses for elementary teachers of science can provide opportunities to build pedagogical content knowledge. One common concern of preservice teachers is how to cope with a preplanned lesson that does not proceed as planned. Providing opportunities for preservice teachers to experience the unexpected actually immerses them…

SCIENCE CONCEPTS IN THE ELEMENTARY SCHOOL CLASSROOMS SHOULD BE BUILT FROM STUDENT EXPERIENCES, NOT MEMORIZED FROM PRINTED MATERIALS. TEACHERS SHOULD BE ALERT AT ALL TIMES AND CONSCIOUSLY ATTEMPT TO SET UP OR CALL ATTENTION TO SITUATIONS PROVIDING OPPORTUNITIES FOR THE USE OF PROBLEM-SOLVING TECHNIQUES. THE FOLLOWING GENERAL AREAS ARE SUGGESTED AS…

Supports the use of a science experiment option in the high school curriculum to enhance student learning. Presents a science experiment rubric and connects the use of science projects with standards. (DDR)

Authors discuss "the scientific method" and assert that laboratory scientists ask questions but seldom state formal hypotheses to be answered by controlled experiments. Authors suggest that experimental results should not be viewed as fact, and students should not be required to memorize the steps of the scientific method. (PR)

Raises questions about the widely accepted rationale of teaching scientific methodology in order to help students become better problem solvers in nonscience settings. Argues that it is better to teach problem solving skills within familiar contexts not complicated by difficult subject matter. (DC)

Implications for science curricula and instructions of new perspectives on scientific knowledge, on nature of evidence, and on how knowledge changes are considered. Argues that much of science education is mired in positivist assumptions and suggests ways in which science instruction can promote a more appropriate epistemological attitude and…

Discusses the notion that scientific knowledge is not dependable and that knowledge is no longer valued as a part of science. Points out that this has led to approaches that aim to teach scientific methods or problem-solving skills rather than scientific knowledge. Contains 19 references. (DDR)

This paper provides materials for a teacher workshop on the application of scientific processes across the curriculum. The approach is based on Taba's Inductive Model, and these materials contain sections on the purposes of Taba's model, teaching strategies used in Taba's model, the concept formation process, interpretation of data, application of…

This research report describes strategies that can be used to enable students to appropriately use the scientific method to solve problems during labs and activities. The targeted population consists of middle school science students in a growing middle class suburban area. Evidence of their lack of understanding and application of the scientific…

Students (n=45) in an introductory course in hydrology used a Vee map to guide their laboratory investigation. The Vee mapping technique was utilized by groups of students working together during the investigation and was graded with a scoring rubric developed by the instructor. At the end of the investigation, students completed a survey…

Examines those theories of learning that have laid the groundwork for classroom approaches that encourage students to become active learners. Summarizes the National Science Education Standards (NCES) Teaching Standards B. (DDR)

Five years ago, an introductory chemistry course for chemists and chemical engineers was redesigned to stress the scientific method, problem-solving, and reasoning skills. Describes: (1) changes made in the course; (2) impacts on student achievement; and (3) student ratings of the course. (JN)

Describes a method of teaching geology and scientific writing to nonscience students that combines active integration of lecture, reading, and laboratory materials with field observations into a writing assignment on a real scientific problem. The writing assignment is completed in stages: a prospectus, a detailed report outline, a bibliography, a…

Problem solving has long been a concern of science educators, with many asserting that problem solving should be both the overriding method and valued outcome of science instruction in American schools. This information bulletin synthesizes studies that deal with the relationships between the teaching of problem solving and secondary school…

Describes a common misconception in the study of mechanics. Cites textbooks as being in error for equating velocity components along the string because the string does not remain taut. Discusses the typical textbook approach to a problem of this nature and the misconception that pervades textbooks in the British Isles. (CW)
