Describes a project based on the collaboration of scientists, science educators, graduate and undergraduate students, and master teachers for the improvement of teaching introductory science courses. Uses action-based research teams (ABRTs) as the teaching tool to change the curriculum, which provides a mechanism for the implementation of changes…

Introduces a project in which students examined the physics, chemistry, and geology of radon and used available technology to measure radon concentrations in their homes. Uses the inquiry process, analytical skills, communication skills, content knowledge, and production of authentic products for student assessment. (YDS)

Discusses the benefits of linking schools in different parts of the world. Provides a list of what to do and what not to do in setting up such a program. Describes some of the opportunities available to teachers and students. (DDR)

Explores the science content knowledge of elementary school teachers and its possible role in helping them teach effectively. Studies the issues in the context of an investigation of the views of elementary school teachers (n=106) who had participated in professional development courses that focused on the topic "natural and processed…

Introduces an integrated unit on scuba science. Studies oxygen in kinetic theory, Boyle's law, Charles's law, Dalton's law, human circulatory and respiratory systems, and diving dangers such as decompression sickness. (YDS)

Discusses the structure of a laboratory course that employs guided inquiry and collaborative learning to increase student preparedness for and intellectual engagement in laboratory investigations, and to give students an understanding and appreciation of a collaborative work environment. Contains 29 references. (DDR)

Presents an activity designed to provide students with opportunities to practice drawing atomic models and discover the logical pairings of whole families on the periodic table. Follows the format of a television game show. (DDR)

Investigates the differences in academic achievement and performance for two groups of at-risk students in large and small group instructional settings when activity-based informal collaboration is applied as a teaching method. Includes 40 references. (YDS)

Does a sensori-motor experience help a physics student understand the movement of molecules in solids, liquids, and gases? Students aged 9-10 were given either traditional demonstrations of solids, liquids, and gases and the variation of molecular motion with temperature (iconic presentation), or they were involved in physical activities as they…

Examines the teaching of science and technology in a new curriculum in the last year of high school in Victoria, Australia. Physics and chemistry were linked to the study of materials and technology. The area of materials related all three subjects but enrollments were much higher for physics and chemistry than for materials and technology. (AIM)

Describes absorption spectroscopy experiments that allow students to explore the mechanisms by which sunscreens and sunglasses provide protection from ultraviolet radiation. Exposes students to absorption phenomena in an engaging way. (DDR)

This study investigated topic features and the effect of topic variation on performance in a test designed to assess the language skills of international teaching assistants in chemistry. Results suggest a relationship between topic of input (as defined by the topic features of concepts, math, and calculations) and test scores. (Author/MSE)

Explores whether construction of integrated knowledge structures by students can be stimulated by concept mapping and better visualization of concepts and their interrelationships. Significant effects of concept mapping as an instructional method could not be detected. (Contains 18 references.) (DDR)

Introduces the computer software program Learning and Understanding through Computer-based Interactive Discovery (LUCID) which is designed to increase student engagement in the learning process. Evaluates the effectiveness of LUCID on student attitudes and grades. (YDS)

A laboratory practical examination was used to compare the investigative skills developed in two different types of general-chemistry laboratory courses. Science and engineering majors (SEM) in the control group used a traditional verification approach (SEM-Ctrl), whereas those in the treatment group learned from an innovative, inquiry-based…
