Analyzes projects developed by preservice teachers enrolled in an elementary science course. Finds that students made a number of different types of mathematical errors and underutilized data representation and summary forms. (Author/MM)

Argues that in future revisions of the National Curriculum for Science the 'big ideas' of science should be presented as a series of 'explanatory stories' that encapsulate the ideas so that they are understandable by both teachers and pupils and can be used as a framework for teaching. Offers an 'explanatory Earth story' based on this model.…

Examines the implementation of a laserdisk-based science curriculum in an elementary school. Issues discussed include ownership of the classroom discussion, constraints on activities, and the teacher's response to the teaching tools. Also examines student attitudes and anxiety toward science. Results indicate little adoption of the curriculum and…

Argues that a strong sense of technical necessity informs the design of the computer-literacy curriculum. As a result, instruction in this area is inadequate at best and dehumanizing at worst. Contains 32 references. (DDR)

Focuses on the history of the organization of chemical principles in chemistry textbooks. Describes a higher-order organizing principle, based in chemical logic and understanding, from which topics and order of presentation are derived. Provides an example of a biochemistry curriculum developed using this organizing principle. (DDR)

Suggests English teachers might draw from authors such as Carl Sagan, Arthur C. Clarke, Mary Shelly and others: (1) to knock down the walls that separate science and literature; (2) to show their interrelationship; and (3) to instill enthusiasm for the study of both. (NH)

Describes the nature, implementation, and value of a spiral curriculum in which topics of study are revisited with each successive encounter building on the previous one. (Contains 12 references.) (WRM)

Investigates the extent to which a new general science curriculum reflecting a constructivist view has influenced the science classroom learning environment in Korea. Results from a validated Korean Constructivist Learning Environment Survey (CLES) indicate that grade 10 students perceived a more constructivist learning environment than grade 11…

Describes a project designed to deliver statistically sound evidence of improved student learning in classrooms using the environment as an integrating context for learning. (DDR)

Reports on a research study designed to understand the influence of education on the level of recycling in communities and counties in Iowa. Focuses on different types of education, distribution methods, expenditures, and messages. (DDR)

Discusses the analytical processes and outcomes of a doctoral study in environmental education that investigated teachers' thinking and practice regarding the contributions of geography teaching to students' environmental education. (Contains 33 references.) (DDR)

Describes hands-on science areas that focus on trees. A project on leaf pigmentation involves putting crushed leaves in a test tube with solvent acetone to dissolve pigment. In another project, students learn taxonomy by sorting and classifying leaves based on observable characteristics. Includes a language arts connection. (PVD)

Analyzes junior high school students' astronomy conceptions by means of a written questionnaire and delineates the main findings. Focuses on the effect on climate of the relative positions of the earth, moon and sun. (Contains 41 references.) (DDR)

Introduces the Science Teacher Education Program (STEP) and its components which can be effectively used in developing countries such as Africa or in countries having problems with science achievement. (Contains 12 references.) (ASK)

Presents science activities suggesting ways to incorporate water into different subject areas such as science, mathematics, history and society, and the arts. (YDS)
