The authors describe a Modeling Instruction program that places an emphasis on the construction and application of conceptual models of physical phenomena as a central aspect of learning and doing science. (Contains 1 table.)

States that the educational mission of instruction in natural science is still not clearly defined. Explains that the unclear mission is revealed by the situation in instruction in physics today as well as by the scholastic achievement in this field. (CMK)

This publication is the final report of the activities performed in the development of an introductory astronomy course operated in a competency based mode. The objective was for the course to be completely opposite from one which emphasizes memorization of factual knowledge. Instead, the student was to be involved in activities where he or she…

The PLATO IV system of computer-based education developed at the University of Illinois is discussed. A brief description of the PLATO system operation is given, and lesson examples are provided for the areas of biology, geometry, chemistry, and physics. Basic problems in the field of computer-based education are discussed, along with possible…

Discusses the concept of kinetic versus thermodynamic control of reactions. Explains on the undergraduate level (1) the role of kinetic and thermodynamic control in kinetic equations, (2) the influence of concentration and temperature upon the reaction, and (3) the application of factors one and two to synthetic chemistry. (MVL)

Explains the reasons for low U.S. score results on the Third International Mathematics and Science Study (TIMSS) and compares them with students from other nations. Swedish high schools scored highest on the science test, which is attributed to their curriculum. Suggests that the majority of students are taught science that is irrelevant for their…

Discusses the implementation and evaluation of the first full year of college freshman integrated natural science curriculum. Identifies separate courses in chemistry and biology as the foundation with physical principles as the unifying theme. Notes all instructors attended all classes. (MVL)
