Understanding the scientific method fosters the development of critical thinking and logical analysis of information. Additionally, proposing and testing a hypothesis is applicable not only to science, but also to ordinary facts of daily life. Knowing the way science is done and how its results are published is useful for all citizens and…

Describes a physics experiment which demonstrates the pitfalls of assuming that a model which represents an ideal system is applicable to a real experiment. Explains how the failure may give greater understanding of the problem and may lead to improvements in the model. (ML)

Students often complain that lectures requiring simultaneous writing and listening is a difficult task. An alternative method is provided to teachers to facilitate note taking by students. (ZWH)

Provided is a model to depict how the development of process skills can be systematically achieved and in turn determine the students' achievement in science practicals. Modified laboratory instruction is compared with conventional laboratory instruction. The results of field testing on 164 ninth grade subjects are described. (MVL)

Presents an identification method which uses the process of elimination to identify pollination systems. Provides the polyclave key, methodology for using the key, a sample worksheet, and abbreviation codes for pollination systems. (MVL)

Describes the construction of durable, inexpensive and large sand-hourglasses for use in controlled experiments that allow students to observe, infer, measure, record data, and predict. This hands-on activity is designed to take place over a three-day interval. Includes materials needed, techniques, procedures, follow-up activities, and resource…

Describes the use of analogy relative to the classical theory of momentum and kinetic energy, and addresses the advantages and disadvantages of this approach with respect to modern physics. Discusses the origins of the billiard ball analogy in the work of Coriolis and its influence on later theories and investigations of nuclear fission, particle…

Reports on the development of a modified Problem-Based Learning approach to a freshman course. Enables faculty to teach basic biochemical concepts and principles as well as their application to clinical cases. Includes the syllabus and workshop goals based on Bloom's taxonomy. (MVL)
