Reports in detail on a year-long case study of multiple-model use at grade 11. Suggests that students who socially negotiated the shared and unshared attributes of common analogical models for atoms, molecules, and chemical bonds used these models more consistently in their explanations. (Author/CCM)

Follows 168 Greek students ages 13-14 involved in a new sociocultural situation--a specially-designed introductory chemistry sequence. Results show that conceptual development occurred during the sequence. (Author/CCM)

Provides a synopsis of the UNITWIN/United Nations Educational, Scientific and Cultural Organization (UNESCO) Chairs scheme in science and mathematics education in southern Africa. Examines the possible impact of the brain-drain phenomenon. Discusses the successes and failures that have attended efforts directed at capacity building in science and…

Argues for the benefits of using historical perspective in the teaching and learning of science. Describes the positive effects of using such an approach during the study of atomic theory with 14-year-old students. (Contains 27 references.) (Author/WRM)

Describes the development of a project-based unit on hot-air balloons used with Israeli junior high school students. Concludes that students in the program gained experience with high-level scientific principles and technological processes, the project allows for a learning environment of cooperation and teamwork, and collaboration between…

Explores factors related to preservice teachers' capacity to understand the learning cycle. Finds that understanding of the learning cycle was related to science teaching outcome expectancy, not to personal science teaching efficacy or to attitudes toward science. (Contains 32 references.) (Author/WRM)

Introduces the ideas of "distal" knowledge of the nature of science and "proximal" knowledge of the nature of science. Suggests that viewing these two kinds of knowledge structures within modern information processing frameworks that delineate roles of epistemological and metacognitive knowledge in learning should guide future research. (Contains…

Reviews the published literature in English on scientific literacy. Discusses the history and various factors that influence interpretations of the concept. (Contains 106 references.) (Author/WRM)

Describes the development, implementation, and assessment of a mixed formal-informal Science, Technology and Society (STS) curriculum that incorporates collaborative projects with case studies, field trips, and formal class sessions. (Contains 44 references.) (Author/WRM)

Presents three interlinked studies aimed at developing a curricular framework for physics education; assessing student interest in the contents, contexts, and activities that are suggested by that curricular framework; and developing a curriculum that is in line with that framework and measuring its cognitive and emotional effects on students.…

Describes the development and validation of a questionnaire, the Teacher Communication Behavior Questionnaire (TCBQ), that assesses student perceptions of five important teacher behaviors: (1) Challenging; (2) Encouragement and Praise; (3) Non-Verbal Support; (4) Understanding and Friendly; and (5) Controlling. (Contains 49 references.)…

Indicates the necessity of curriculum frameworks that enable all students to achieve their maximum potential literacy; to create their own knowledge; and to develop in directions unique to their needs, interests, abilities, and perspectives--that is, to become self-actualized. (Contains 65 references.) (Author/YDS)

Applies self-determination theory to investigate the effects of students' course-specific self-regulation and their perceptions of their instructors' autonomous support on adjustment and academic performance in a college-level organic chemistry course. Hypothesizes that students taking the organic chemistry course for relatively autonomous reasons…

Focuses on student capacity to develop and assess arguments during a high school genetics instructional sequence, and on the location distinction in argumentation discourse between "doing science" vs. "doing school" or "doing the lesson". (Contains 37 references.) (Author/YDS)

Analyzes a teaching episode to determine how a conflict is perceived and overcome by students as a result of verbal interaction between the teacher and the students. Discusses the particulate nature of matter with students aged 15-16 after observing a glass of water containing a rock and an ice cube. (Contains 25 references.) (Author/YDS)
