Examines the problem of sex discrimination and sex-role stereotyping with respect to instruction in undergraduate science laboratory classes. Deals specifically with the behavior of instructors as they interact with students during laboratory sessions. A significant difference in male and female teacher behavior was found in three basic areas.…

Describes the building design and interior laboratory features of the science center at Australia's Sturt C. A. E., an institution of higher learning. Photographs are included. (MLH)

Gives a step-by-step description of a problem-solving microscale chemistry laboratory to show how this implementation of problem-solving teaching can be put into practice. Pedagogical and practical issues are discussed. (DKM)

Investigates how microcomputer-based laboratory (MBL) activities specifically designed to be consistent with a constructivist theory of learning support or constrain student construction of understanding. Analysis of students' discourse and actions reveal that students invented numerous techniques for manipulating data in the service of their…

Describes cooperation with the Saint Louis Zoo to provide opportunities for elementary school students to learn about bones, how animals move, what they eat, and how much they grow. Uses biofacts which include bones, skulls, and other parts to make the laboratory a hands-on experience for students. (YDS)

Three educational institutions had markedly different furniture needs--home-style furniture for college student residences, high-density storage for high school science labs, and computer lab furniture for a K-12 school district. However, all used a systematic approach to purchasing that involved users, knowledgeable colleagues, and technical…

Discusses a number of important laboratory-related terms worthy of consideration and suggests a classification scheme that may be used to rate individual activities while implying a direction to enhance such exercises. Highlights implications of classifying laboratory activities and clarifying laboratory vocabulary. Contains 11 references. (JRH)

Describes a yearlong school-based project involving the Maui Public Health Department to define mosquito behavior and distribution. (KHR)

Describes a physiology laboratory designed to localize digestive enzymes within the digestive tract of cockroaches and develop a general conclusion about the similarities to mammalian digestion. This approach not only demonstrates the practicality of lecture material, but also provides a springboard for independent research opportunities.…

Investigates the use of a hands-on laboratory program to improve attitudes toward science and increase achievement levels in science knowledge among students in a 9th grade physical science course. Reports that students with regular laboratory instruction scored significantly higher in achievement of science knowledge than those without laboratory…

Describes a two-hybrid research project incorporated into a molecular biology course that contains both a lecture section and a laboratory section. (Author/KHR)

Describes the use of a laboratory-based exam in mechanics that makes students use metersticks, stopwatches, and spring scales to examine physical situations, make some calculations to predict what will happen, and then test their predictions. Includes a description of the lab stations for the actual exam. (JRH)

Describes the Iowa General Chemistry Network that was developed to change content, teaching, and learning methods of introductory college chemistry courses. Highlights include using the Iowa Communications Network for distance education and curriculum reform, using the Internet and World Wide Web, and chemistry laboratory experiences and…

Presents information on owl's taxonomy, characteristics, and influences on man. Describes owl pellets, which are digestive discards, and explains how they can be used to determine the owl's diet as a science activity. (PR)
