Earth Systems Science (ESS) is emerging rapidly as a discipline and is being used to replace the older earth science education that has been taught as unrelated disciplines--geology, meteorology, astronomy, and oceanography. ESS is complex and is based on the idea that the earth can be understood as a set of interacting natural and social systems.…

Describes, and illustrates by reference to chemistry, a systems approach to the development of instructional segments. Uses a model with Behavioral, Temporal, and Substantive elements as axes. (AL)

Presents an inventory of processes of scientific inquiry and describes its use in curriculum development and instructional planning. (AL)

Discusses development and use of an aquatic studies conceptual scheme which has been used in the Project COAST (Coastal, Oceanic and Aquatic Studies) at the University of Delaware. Sample concepts and results from field testing of the curriculum are included. (DH)

Presents a student centered science curriculum model utilizing inquiry strategy and language rich experiences to develop student skills of questioning, thinking, speaking, listening, and reading. (SL)

Explains the "deliberative inquiry model," a strategy developed for investigating science education in Canada. Assumptions of the model are addressed, with information on position papers, curriculum policies, textbook analysis, teacher surveys, and case studies provided. Indicates that the project has created momentum for deliberation…

In this article a general model of mastery learning is developed and discussed using data gathered from operating applications of the mastery model in college classrooms. Suggestions for the implementation of the mastery model in the high school are also presented. (HM)

Investigates how an inservice course using the Investigative Science in Elementary Education-Instructional Television (ISEE-ITV) model of instruction supported by professional reinforcement affected the attitude of elementary teachers toward a leadership role within their respective school buildings. (HM)

Uses examples related to a head of cabbage to discuss: (1) sensory development in children; (2) the integration of sensory and cognitive involvement; and (3) a child's mode of exploring and discovering. Also discusses why science curricula need to be organized around a paradigm that is holistic. (JN)

Examines the impact of one unit of a curriculum module for sixth grade from the Model-based Analysis and Reasoning in Science (MARS) project. Provides an overview of this unit on mass and discusses three aspects of the evaluation of the unit. Contains 22 references. (DDR)

This inquiry examines the personal attribute and environmental factors that contribute to and impede science teacher-leader development. Using a narrative approach, the inquiry focuses on the experiences of three teachers in three different New Zealand primary schools (years 1-6) as they develop in their capabilities as science teacher-leaders…

Discusses a study which examined the interpretive process used by high school chemistry teachers in translating curriculum materials into classroom practice. Results indicate that differences exist among teachers but that commonalities are greater. Explains the functional paradigm concept and its value for the interpretation of curriculum…

Explains cognitive basis for change in science paradigms using Watson-Crick DNA model to illustrate concepts of "normal" versus "revolutionary" science. Examines these concepts in light of teacher preception of science, and discusses implications for the practice of science education. (JM)
