Study investigated whether the use of videotaped models demonstrating effective teaching strategies in an elementary science lesson would promote increased use of effective questioning strategies among preservice teachers (n=38). Results show that the use of the videotaped teaching models increased the use of high-level, divergent,…

Presents an experiment that measures the acceleration and velocity of a model rocket. Lift-off information is transmitted to a computer that creates a graph of the velocity. Discusses the analysis of the computer-generated data and differences between calculated and experimental velocity and acceleration of several rocket types. (MDH)

Discusses Vee mapping, a technique to assist students in categorizing the relationship between the conceptual and procedural aspects of science. Presents a study to investigate elementary education majors' (n=27) use of the Vee heuristic and concept mapping for the construction of knowledge; attitudes toward learning science in collaborative…

Provides an example of the integration of science and mathematics learning of one high school physics student in a constructivist classroom. Discusses the student's integration of mathematical and nonmathematical representations and of different mathematical representations in a nonuniform acceleration experiment. Describes a model for integrating…

Describes an activity in which the students utilize the mathematics concepts of ratio, proportion, and data tabulation to examine the relationship between air pressure, temperature, and humidity. Students learn to approximate partial pressure by using humidity and temperature readings and by interpolating from the vapor pressure-temperature table.…

Provides background information on landfills and describes an activity where students learn how a modern landfill is constructed and develop an understanding of the reasons for several regulations regarding modern landfill construction. Students design and construct working models of three types of landfills. (PR)

Describes a collaborative reform effort among three school districts and the University of Charleston to meet the diverse needs of middle school science students with mild to moderate disabilities. The article discusses the design and implementation of the collaborative model, indicators of its success, and recommendations for similar efforts. (SM)

Describes using the movie "Jurassic Park" as a foundation for a middle school interdisciplinary unit involving science, math, language arts, history, and geography. Suggested books and activities are presented. (PR)

Presents an activity in which students develop science process skills by making inferences as to the contents of a "mystery" box from observations based on their sensory perceptions. Provides instructions for implementing and extending the activity. (MDH)

Explorer is an interactive environment based on a constructivist epistemology of learning that integrates animated computer models with analytic capabilities for learning science. The system includes graphs, a spreadsheet, scripting, and interactive tools. Two examples involving the dynamics of colliding objects and electric circuits illustrate…

Examined the effects of implementing the criterion-referenced assessment system on the views of year 10 students and teachers in 2 schools. Students and teachers were generally positive toward these methods of assessment. There was some sex bias in aspects of the system with females performing better on skill assessments than males. (MDH)

Describes a course for graduate science education students in the history, philosophy, and nature of science. Topics addressed include the course motivation and evolution; aims, topics, and goals; organization and instructional methodology; a reading list; projects; and grading and evaluation. (PR)

Describes an activity to develop students' skills of observation and recordkeeping by studying the growth of a tree's leaves during the spring. Children monitor the growth of 11 tress over a 2-month period, draw pictures of the tree at different stages of growth, and write diaries of the tree's growth. (MDH)

Provides five fully developed library media activities that are designed for use with specific curriculum units in nutrition, reading and language arts, science, and social studies. Each activity identifies library media skills, objectives, grade levels, resources, instructional roles, activity and procedures for completion, evaluation, and…

Presents curriculum guides for elementary instruction in the areas of industrial arts, social studies, mathematics, science, and reading/language arts. Each lesson plan describes library media skills objectives; curriculum objectives; grade levels; resources; instructional roles; activity and procedures for completion; evaluation; and follow-up…
