Suggests that the teaching/learning/research process should be rethought of as a collaborative social learning for constructivism to be meaningful in science education. Includes perspectives on George Kelly's personal construct psychology and Glaserfeld's radical constructivism. (AIM)

Discusses the role of writing about problem solving in the development of mathematics and science skills. Provides examples of student writing in math and science to show students' enhanced engagement and cognitive awareness. (JPB)

Most teachers use multiple intelligence theory in teaching but evaluate student learning with traditional assessment methods. Focuses on classroom assessment and advocates that students' should be evaluated using a variety of approaches. Recommends that teachers make their evaluations more objective and reliable. (YDS)

Suggests that the perspectives developed by humanities as part of education in science, technology, and medicine can offer enrichment in ways that lead to both use and delight. Sketches some activities at the Imperial College of Science, Technology and Medicine (ICSTM) in London concerned with liberal education and describes some of the…

Describes science curriculum for elementary children which incorporated Vygotskian approach to development of students' ability to engage in persistent, systematic inquiry. Discusses three factors: (1) instruction began by introducing ideas that are central and general to the discipline; (2) students invented and adapted cultural tools for…

Describes an activity in which students determine where wind chime tubes should be supported and struck to give the best tone, then find the frequency of the tubes. This activity can be used to introduce ideas on significant figures, experimental error, types of variation, peer review of results, seeking empirical relationships with data, and…

Advocates using computer-simulated learning environments to allow students to develop their own problem-solving rules when it comes to collecting and evaluating scientific data. Describes the use of "Identibacter interactus" to simulate identification of an unknown microorganism. (WRM)

Describes an experimental system based on an engineered strain of bakers' yeast that is designed to involve students in the process by which scientific knowledge is generated. Students are asked to determine why the yeast grow to form a reproducible pattern of red and white. (WRM)

Uses data from the Third International Mathematics and Science Study (TIMSS) to determine the extent of Israeli students' ability to give scientific explanations of events in earth, life, and physical science. Finds student explanations to be generally simple, often incomplete, and often consisting only of descriptive or teleological explanations.…

Tests the hypothesis that two general developmentally-based levels of hypothesis-testing skills exist. Finds a positive relationship between level of hypothesis-testing skill and performance on a transfer problem involving the test of a hypothesis based on unobservable entities. Also finds a positive relationship between level of…

Presents an activity that uses supermarket chemicals to perform a clock reaction in which the endpoint is signaled by an abrupt change in the appearance from colorless to blue-black. This activity can be used to explore reaction kinetics and the effect of reactant concentrations on the apparent rate of reaction. (DDR)

Describes an iodine clock reaction that produces an effect similar to the Landolt clock reaction. This reaction uses supermarket chemicals and avoids iodate, bisulfite, and mercury compounds. Ascorbic acid and tincture of iodine are the main reactants with alternate procedures provided for vitamin C tablets and orange juice. (DDR)

Describes a dramatic chemical demonstration in which chemicals that are black and white combine to produce a colorless liquid. Reactants include tincture of iodine, bleach, white vinegar, Epsom salt, vitamin C tablets, and liquid laundry starch. (DDR)

Reports the discovery of an efficient base composition for making bengal lights that is obtained with potassium chlorate and thiourea. Combining this mixture with appropriate flame coloring can produce several impressive bengal lights. (DDR)

There have been increasing efforts among science educators to move students away from learning about science towards learning "to be" scientists. To move in this direction, there is a need to change the epistemology of the learning of science from instructivism to one of social constructivist learning. The purpose of this research is to…
