Presents an online trivia game on laboratory safety. (YDS)

Improvements in the mechanism of the whirlybird used in the Science Curriculum Improvement Study (SCIS) unit "Subsystems and Variables" are presented. Variables which can be investigated using this device are discussed. An illustration of the improved device is provided. (CW)

Described is a series of computer tutorials developed to teach students a logical method of problem solving for chemistry. The structure, pedagogy, and problem-solving strategies of the computer software program are described. (CW)

Describes teaching strategies that help students improve problem solving skills. Lists three factors good problem solvers were found to possess. Gives step by step instructions for solving problems. (MVL)

Described are the use of two different tests designed to test for selected inquiry skills. Procedures, tests used, and results in several different countries are presented. Implications for classroom instruction are discussed. (CW)

Uses a discrepant event to teach students about volume and area. Outlines directions for class demonstration, needed materials, questions, a story problem, and related activities to perform this assignment. (Author/RT)

Describes an intelligent tutoring system named MENDEL, including problem GENERATOR, TUTOR, student MODELER, ADVISOR, hypothesis CHECKER, and problem SOLVER. This software may be used by high school or university biology students as a tool for learning concepts and problem-solving strategies in transmission genetics. (YP)

Describes the integration of text previews (teacher-developed synopses of the text) and three-level study guides (encouraging factual, inferential, and problem solving responses). Claims a combination of these constitutes a powerful strategy for content area reading. (RS)

Examines the rise of the general science course and its implications for the reform of secondary science education. Concludes that while recent reforms emphasize the personal and social character of science and the use of the scientific method, they will not necessarily make students more scientifically literate or train them to think about…

Describes an extended problem-solving activity utilizing drift-bottles that encourages students to deduce probable and great-circle drift-bottle routes, to use logic based on unit calculations, and to estimate the distance traveled and the minimum velocity of these drift-bottles. Includes materials needed, learning objectives, procedures,…

Describes the importance of estimation in science for planning projects, conducting experiments, and developing theories. Defines order of magnitude. Provides explicit mathematical equations and calculations to estimate answers for seven provocative physics problems. Includes nine additional open-ended problems with hints and solutions. (PR)

Reports observations of primary teachers (n=14) efforts to provide activity-based lessons for their pupils. Teachers' beliefs that their lessons were student-centered were not confirmed by the observations of the lessons. Discusses implications of the findings for inservice teacher education and parental involvement. (MDH)

Reports on a study of the effects of computer-simulated experiments (CSE), problem solving, and conventional approaches on high school students' chemistry achievement, science process skills, and attitudes toward chemistry. Testing indicated CSE and problem solving produced greater achievement in chemistry and science process skills. CSE produced…

At a middle school in suburban Pittsburgh, Pennsylvania, administrators and teachers used the cognitive domain of the National Association of Secondary School Principals' Learning Style Profile to design "products" that helped compensate for underachieving sixth and seventh graders' skill deficits in mathematics and science. Success…

Describes a method of teaching geology and scientific writing to nonscience students that combines active integration of lecture, reading, and laboratory materials with field observations into a writing assignment on a real scientific problem. The writing assignment is completed in stages: a prospectus, a detailed report outline, a bibliography, a…
