Compares aspects of creativity in science between students enrolled in concept-oriented classes and those enrolled in issue-oriented classes. Focuses on student outcomes and creativity. Shows that science teachers were convinced of the necessity for middle school science teachers to be portrayed as supporting students' exploration, explanation,…

Describes similarities and differences between modeling cycles and stages of development. Includes examples of relevant constructs underlying children's developing ways of thinking about fractions, ratios, rates, proportions, or other mathematical ideas. Concludes that modeling cycles appear to be local or situated versions of the general stages…

Reports on the findings of a study designed to develop three-dimensional virtual reality technology (VRT) learning programs for middle school students and evaluate the program's educational value. Focuses on the topic of structure and function of the eye. Concludes that VRT simulations allow comfortable interaction with computers and increase the…

Explores the attempts of a group of preservice elementary school teachers to generalize a repeating visual number pattern. Discusses students' emergent algebraic thinking. Indicates that students' ability to express generalities verbally was not accompanied by algebraic notation, but participants often perceived complete and accurate solutions…

Describes an effort to incorporate standard composition exercises into a sophomore-level discrete mathematics class. Provides an example of how peer review can be integrated with a mathematical curriculum through the writing of proofs. (Author/KHR)

Investigates the development of park visitors' knowledge, values, and beliefs during their visit to the Midway Geyser Basin. Draws on prior work in the areas of museum and informal education, and public understanding of science and cognitive psychology. Interprets the results in terms of park visitors' knowledge systems, how the experience…

Reports on the Victorian Science in Schools Research Project (VSSRP) which was developed to help teachers support student learning of science content. Reviews research on student learning of science concepts and traces changes over the last two decades. (Contains 46 references.) (Author/YDS)

Investigates whether preschool children aged 4.5-6 can construct the concept of mechanical stability through structured hands-on activities that involve the building of a tower on an inclined plane and the use of cans of various sizes and weights. Presents a theoretical framework for teaching and learning physics in the early years. (Contains 47…

Documents the experiences of two teachers and their kindergarten and first-grade students in working with calculators as an ongoing and integral component of their mathematical programs. Focuses on ways that the children and teachers use the calculator to develop ideas of number through explorations of numerals, counting, number magnitude, and…

Explores ways to help children make connections between whole-number multiplication and their notion of a fraction. Illustrates an approach to constructing fraction concepts that builds on children's whole-number knowledge using specially designed computer tools. (KHR)

Discusses one way of addressing the difficulty of mastering a large number of concepts through the use of ConcepTests; that is, multiple choice questions given in a lecture that test understanding as opposed to calculation. Investigates various types of ConcepTests and the material they can cover. (Author/KHR)

Examines the effectiveness of evidence-based medicine and critical appraisal teaching at the postgraduate level. Conducts a comprehensive search and identifies 17 studies. Shows a significant improvement in knowledge but not in attitude, skills, or behavior. (Author/KHR)

Investigates student learning in a mathematics enrichment program offered via the Internet. Describes a course aimed at fostering students' capabilities to work like a mathematician. Examines students' correspondence and work for evidence of how students were working mathematically. Explains how to design both face-to-face and on-line teaching to…

Presents lab exercises in which students use the microscope to study cells. Describes these activities as allowing students to work independently and become more proficient at microscope use. Students also gain a deeper understanding of the more invisible world of science. (Author/KHR)

Discussion of why many experimental educational programs seem promising initially but disappointing when widely applied leads to detailed examination of the concept of "explanation." A proposed model for planning classroom work involves: (1) focusing students on the nature of the problem; (2) orienting pupils to a theoretical construct; and (3)…
