Determined the influence of two types of practice (microteaching and modeling) used during process skills instruction on 29 preservice elementary teachers' acquisition and classroom utilization of those skills. Results indicated significant gains in skill acquisition using both methods, although neither method was found to be superior. (DS)

Determined if modifying Bloom's mastery strategy improves science achievement during a six week human physiology unit. Findings indicate only a small degree of improvement in achievement of 185 students. Suggests that the approach employed in this study would be impractical for the biology classroom. (DS)

Describes an inexpensive physics apparatus and experiment to dynamically determine Young's modulus for thin reeds and wire samples. (HM)

Five types of models are discussed as they relate to their function in the sciences and science teaching. These include scale, analogue, mathematical, theoretical, and archetypal models. (SA)

Presents a 52-item bibliography of works in the ERIC collection dealing with science instruction at two-year colleges. The entries cover the areas of general science, agriculture, biology, chemistry, earth science, economics, engineering, environmental sciences, interdisciplinary sciences, social science, mathematics, physics, psychology, and…

Described are different chemistry curricula that use lecture-experiments. Different components are discussed within the lecture-experiment format, such as determinism, memory, note taking, descriptive chemistry, and holistic chemistry. Also discussed are different personalities in chemistry education. (DS)

Described is a Piagetian learning cycle based on Monte Carlo modeling of several simple reaction mechanisms. Included are descriptions of learning cycle phases (exploration, invention, and discovery) and four BASIC-PLUS computer programs to be used in the explanation of chemical reacting systems. (Author/DS)

Uses the irruption theory in explaining the occurrence of the Darwin finches in the Galapagos Islands as an example of how alternative theories can be presented in an educational setting. Advocates the comparison of alternative theories to encourage creative thinking and a critical attitude. (CS)

A method is provided for teaching reading comprehension of scientific or technical texts in a foreign language. The method involves analyzing language patterns and using some memorization for terminology. (MSE)

Reviews computer assisted instructional (CAI) technology now available in large scale systems such as PLATO, and in videocassette-linked computer systems. Computer Managed Instruction (CMI) is described as a means of fitting instruction to the student's cognitive style. Discusses briefly cable TV, electronic newspapers, desk-top computers, and…

The Lawrence Hall, a science museum and teaching center in Berkeley, California, is providing thousands of students and teachers with hands-on experience with personal computers. This article describes how Lawrence Hall promotes computer awareness and provides science instruction through microcomputer-controlled interactive museum exhibits.…

Presents a collection of ideas of activities using puppetry in helping young children learn elementary science concepts. (SA)

Presents activities for the elementary teacher to use in helping children to enjoy a small path of undeveloped land in an urban area. Teaching about plant roots is explained. Also included is the equipment needed and how to prepare for the root activities. (SA)

Presents the steps for drawing a block-diagram from a map in the area of structural geology. The author recommends first platting on the orthographic net, all directional data with respect to geographical reference axes. (Author/SA)

Outlines a variety of laboratory procedures, discussions, and demonstrations including in vitro contraction of muscle fibres and muscle proteins, sucrose density-gradient centrifugation, fern spore development, digestion of starch, construction of a small mammal trap, microscope selection, and occurrence and toxicity of mycotoxins.
