Discusses the use of graph theory to aid in the depiction of organic molecular structures. Gives a historical perspective of graph theory and explains graph theory terminology with organic examples. Lists applications of graph theory to current research projects. (ML)

Traces the development of bonding theory and notes the influence of preconceived theory upon this development. Considers ideas of alchemy, Newton, Dalton, Lewis, and quantum mechanics. Suggests a move away from conservative descriptive approaches of bonding theory. (ML)

Follows an experimental program where 30 trained high school science teachers used 6 to 10 students each to produce an original experimental environmental research project. Offers suggestions to improve science in high schools. Lists methodology of several of the projects and describes others. (ML)

Discusses a teaching method using investigational skills for Nuffield A-level Physics including assessment technique, change of the assessment criteria, advice for choosing the topic, and future development. (YP)

Research into student attrition in college science education has identified fundamental differences between the way students in the physical sciences are taught and the way students in the social sciences or humanities are taught. Implications for academic advising include having advisors attend science classes and informing science faculty about…

Reviews emerging applications of microcomputers and hypermedia to assessment. Use consists mainly of computerized test administration of multiple-choice tests drawn from item banks. Significant advantages are possible in several areas including immediate feedback to students, formative evaluation with remediation possibilities, and monitoring…

Presents one educator's efforts to renew himself as a professor of education by returning to the secondary physics classroom, taking his student teachers with him. The experience made him examine new perspectives on physics students, preservice physics teachers, school science teachers, experienced teachers turned graduate students, and teacher…

Technology can be useful in physics classrooms, though teachers must be careful not to let technology remove students from first-hand experiences with nature through observation and experimentation. The paper examines how to enhance physics instruction using computers as graphing tools, for data collection, and as real-world simulators. (SM)

Describes an introductory biology course designed to enhanced the science learning of elementary education majors. A consideration of students' learning styles and interests combined with a belief that science academic talent is not a selective process, resulted in a biology course that was academically challenging and enjoyable for students. (ZWH)

Diverts from the traditional approach to teaching ecology and moves toward a more interdisciplinary approach by engaging students in a field trip to the Rocky Mountains. Using examples and insights, the author describes and identifies opportunities for promoting knowledge, understanding, and awareness of the environment and its surroundings. (ZWH)

Two studies examined the construction of children's beliefs about projectile motion of a ball rolled off a table. Describes the concepts used by children, analyzes their use as a function of age, and gives a naturalistic description of their use. Results indicate that appropriate instruction can remediate misconceptions. (MDH)

Presents five integrated mathematics and science lessons in which students investigate the characteristics, behavior, lifecycles, and motion of mealworms and the feasibility of raising mealworms for profit. Purpose, time, materials needed, procedures, and extensions for each activity are provided. (MDH)

Provides strategies for adapting microscope activities for students with disabilities. The following factors are considered: (1) mainstreaming strategies; (2) laboratory techniques; (3) observing and classifying; (4) vocabulary and terminology; and (5) safety. (ZWH)

Includes book reviews of science trade books written in Spanish from the following categories: (1) Animals, (2) Encyclopedic Series, (3) Nature, and (4) Physical Science. (ZWH)

Presents answers from a teacher, a curriculum developer, and the educational literature to the question "How is hands-on learning evaluated?" Describes different approaches to performance-based assessments including performance tasks, observational checklists, and portfolios. (PR)
