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)

Suggests strategies for addressing cases of student conscientious objections to the use of animals or animal parts in science teaching. Advises departments to have a written policy and philosophical statement, to use an Animal Care and Use Committee and to explore student motives. (PR)

Guidelines are offered to research administrators for reducing the volume of hazardous laboratory waste. Suggestions include a chemical location inventory, a chemical reuse facility, progressive contracts with chemical suppliers, internal or external chemical recycling mechanisms, a "chemical conservation" campaign, and laboratory fees for…

Ethnographic study of science lab technicians' troubleshooting suggests that they possess most of a lab's contextual knowledge and skill and play a critical role in the production of scientific knowledge. However, because contextual knowledge is less valued than formal knowledge, technicians experience status inconsistencies. (SK)

Provides a neurocomputational account of knowing and learning and grounds situational cognition theory in a neurocomputational model of neuronal activity. Presents the advantages of this theoretical approach. Contains 60 references. (DDR)

Examines the effects of investigative, open-ended, and inquiry-based labs on students' ability to ask high-level and open-ended questions. Recommends combining direct instruction in questioning with increased background information to improve students' questions. (Contains 19 references.) (YDS)

Investigates the reasons for data fabrication among undergraduate and graduate students. Presents several examples of getting misled by the candle and tumbler demonstration. Concludes that presented facts, concepts, or principles increase the incidence of data cooking. (YDS)

Introduces an undergraduate level problem-based analytical chemistry laboratory course integrated with an environmental law course. Aims to develop an understanding among students on the use of environmental indicators for environmental evaluation. (Contains 30 references.) (YDS)

Provides examples of four university science buildings whose design fosters interdisciplinary interaction among students coupled with lab flexibility. Design concepts, innovations, and building layouts are examined. (GR)

Presents a science unit in which students design and test a sample of concrete and later redesign it to improve the strength of their sample under compression. (YDS)

Describes a project that applies problem based inquiry learning units to an introductory chemistry laboratory curriculum. Uses web technologies to support instruction. (Contains 25 references.) (YDS)
