Describes a course, "Great Ideas in Science," for undergraduate nonscience major students. The course emphasizes a few key overarching concepts in physics, chemistry, geology, and biology to introduce students to the essential aspects of science without getting involved in the complex vocabulary or rigorous mathematical derivations. (PR)

The principles of magma addition and liquid layering in magma chambers can be demonstrated by dissolving colored crystals. The concepts of density stratification and apparent lack of mixing of miscible liquids is convincingly illustrated with hydrous solutions at room temperature. The behavior of interstitial liquids in "cumulus" piles…

Presents a unit on evolution and creation theories in which students explore the legal issues surrounding the teaching of evolution and creation in biology. Students write preliminary essays, study conflict resolution techniques, and conduct a moot trial of the Scopes case of 1925. A course outline is provided. (MDH)

Asserts that education cannot be limited to the confines of a textbook but must be a true window to the world. Argues that this can be achieved through curriculum and thematic teaching. Provides suggestions for designing and teaching integrated, thematic units. (CFR)

Presents a poster for classroom use backed by a teacher's guide to be used in conjunction with the Public Broadcasting Service's six-part series "Space Age." Lists major concepts explored in each program. Includes questions for classroom discussion. Suggests classroom activities to accompany the lessons from the television programs. (DK)

Discusses ways in which marine biology can be integrated into the physics classroom. Topics suggested for incorporation include the harmonic motion of ocean waves, ocean currents, the interaction of visible light with ocean water, pressure, light absorption, and sound transfer in water. (MDH)

Examines the relationship between new biology teachers' subject matter knowledge and classroom discourse, contrasting classroom discourse during laboratory investigation with discourse during other classroom activities. Data analysis suggests that knowledge and control are related but in ways unique to the communicative context of the laboratory.…

Investigates how 20 English primary teachers understand the concepts of force and gravity. Uses the interview about instances technique. Finds teachers' views of these concepts are not in accord with accepted scientific interpretations but similar to those of children's views. Discusses implications of the findings. (NL)

Explored are ways in which spreadsheets can be used in the teaching of chemistry. Some of the limitations of using algebraic modelling tools are highlighted. Several example applications are provided. (CW)

Discusses three teachers' syntactical subject matter knowledge in science. The focus of the discussion is the link between teachers' views of the growth of scientific knowledge and the methods they use to help students construct a knowledge of science. (IAH)

The Council for Advancement and Support of Education's Professor of the Year, Vicente Villa, is a first-generation college graduate who teaches biology at Southwestern University (California). He began his study of biology in college and provides an important role model for Hispanic-American students. (MSE)

Describes problems in teaching problem solving and summarizes research in this area. Presents Guided Design or Guided Decision Making as a problem-solving approach in which groups of students work their way through a model of the problem-solving process as they wrestle with a discipline-specific situation. (PR)

Discusses some of the definitions of successful instruction stated or implied by researchers in science education and examines reasons for the diversity of definitions. Describes how a high school chemistry teacher decides whether his or her instruction is successful and how these assessments influence instructional practices. (PR)

Based on the premise that body experiences interfere inconveniently with scientific ideas in mechanics instruction. Suggests that learning processes start with body experiences and, with guidance, transform them into something scientific. Discusses this process for the static and kinetic aspects of force and for measurement. (MDH)

Investigates predictors of Korean student's choice of science track (n=665). It was concluded that attitude toward science track influences the intentions of the students. (PR)
