Discusses how, through a series of sample problems and solutions, the notion of force as momentum flow can serve as the basis for vastly expanding the importance of Newton's third law as experienced by students in elementary mechanics courses. (Author/HM)

Provides both a rationale and framework for Earth systems education and a description of the early development of the Program for Leadership in Earth Systems Education (PLESE). Presents the seven basic understandings that form the conceptual basis for the PLESE program. (five references) (MCO)

Describes a Science-Technology-Society (STS) course implemented in Iowa that utilizes the National Science Teachers Association guidelines for STS courses. (PR)

During the last 10 years, cognitive science researchers have produced research findings that have great potential for increasing students' understanding of science. However, commercial publishers continue to produce textbooks and teacher's guides in traditional ways. This project developed a prototype unit which used an alternative approach to…

Discusses the use of formulae in the teaching of chemistry as part of the individual culture and of the conceptual structure of chemistry. A historical viewpoint on the procedures for structure representation and some educational implications for teaching chemistry in Italy are also presented. (HM)

Presented are the reasons why the earth sciences must play a major role in curriculum renovation. Philosophical, methodological, and conceptual contributions to K-12 curriculum content are discussed. (KR)

This guidebook consists of 11 chapters. Chapter 1 provides information on organizing a physics course, considering such topics as types of physics programs, laboratory work, curriculum selection, and computers/calculators. Chapters 2 to 11 focus, respectively, on the topic areas of forces, motion, dynamics, energy, heat, the atomic structure of…

Discusses a questionnaire sent to 763 Society for College Science Teaching members to identify problems of teaching nonmajors. Notes the questionnaire had a high return rate. Lists the eight major problems: post negative experiences; motivation; what to teach; abstractions; how to introduce relevance; staying power; inquiry material; and…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The inquiry reported focuses on problems/difficulties of learning about the concept of "force" through…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The investigation reported focuses on primary, intermediate, and secondary students' (N=41) ideas about selected…

Observational techniques were employed to gain insights into students' experiences from three perspectives (learner, teacher, and observer) as related to four aspects of a set task (nature of the task, including its purpose; how the task was carried out; perceived significance of outcomes achieved; and significance of outcomes in terms of science…

This paper, designed to be used in conjunction with a video-tape developed by the Learning in Science Project (Primary)--LISP(P)--shows excerpts from some of the interview schedules used to examine children's ideas about floating and sinking. These interviews involved the use of "interview-about-instances" (IAI) cards (included in an…

This study investigated the meanings and ideas held and questions asked by children (ages 7-14) about floating and sinking (in water). Data were collected from interviews using "interview-about-instances" (IAI) cards (included in an appendix) and 10 objects which either floated or sank. Additional data were collected from classroom…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The investigation reported focuses on the concepts of "living" held by 32 students in four different…

One area explored in the second (in-depth) phase of the Learning in Science Project was "children's science," defined as views of the world and the meanings for words that children have and bring with them to science lessons. The investigation reported focuses on students' thinking regarding their views on friction. Students (N=47) were…
