The authors investigated whether the amount of instructional guidance affects science learning and self-efficacy. Sixty 9- and 10-year-old children were randomly assigned to one of the following three instructional conditions: (a) guided instruction consisting of examples and student-generated explanations, (b) direct instruction consisting of a…

The impulse to investigate the natural world is deeply rooted in our earliest childhood experiences. This notion has long guided researchers to uncover the cognitive mechanisms underlying the development of scientific reasoning in children. Until recently, however, research in cognitive development and education followed largely independent…

We explore the immediate and longer term consequences of different types of instruction about a central topic in middle school science: the "Control of Variables Strategy" (CVS). CVS represents the procedural and conceptual basis for designing simple, unconfounded experiments, such that unambiguous causal inferences can be made. CVS…

Reviews the objectives of laboratory work in chemistry education, current laboratory practice, and factors likely to impact on the nature of laboratory work in the future. Proposes that more investigation-style laboratory work be provided in order to foster the development of students' investigation skills. (Author/MKR)

The goal of this paper is to sketch the epistemological roots of constructivism, to clarify certain implications of Piaget's constructivist theory for science education, and to explicate the issues surrounding a specific research study and its replication. Constructivist epistemology is described in terms of its emergence from rationalist,…

Describes Socratic Dialogue Inducing (SDI) laboratory methods and procedures developed to increase conceptual understanding in introductory physics laboratories. Gives an example of a typical beginning SDI lab manual section and a representative Socratic dialogue. Describes several examples of laboratory experiments developed for the SDI method.…

Investigated the interaction between science teaching strategy (semideductive, structured inductive, hypotheticodeductive) and selected learner characteristics (Piagetian cognitive level and field independence) in terms of student achievement in science. Achievement of undergraduate elementary education majors (N=77) in a general science program…

Discusses the value of nature education to early childhood education. The domains of adaptive, aesthetic, cognitive, communication, sensorimotor, and socioemotional development are discussed. Suggests that because young children learn primarily through their senses and motoric manipulation, they are excellent candidates for nature education…

Background information and exemplary units for teaching science in Georgia's middle school grades are provided. Discussed in the first section are: (1) the rationale for including science in middle school grades, focusing on science/society/technology, science/social issues, scientific reasoning, and scientific literacy; (2) role of science…

Insights gained from experience and research on language minority students' academic success are reviewed as background for presentation of a curriculum that is bilingual and content-based and uses cooperative learning techniques. First, findings on three elements of success (interest and motivation, intelligence and development, and psychosocial…
