Describes Socratic Dialogue Inducing (SDI) laboratory methods and procedures developed to increase conceptual understanding in introductory physics laboratories. Gives an example of a typical beginning SDI lab manual section and a representative Socratic dialogue. Describes several examples of laboratory experiments developed for the SDI method.…

A videotape series produced by the Annenberg/CPB Math and Science Collection demonstrates college and secondary students' misconceptions about everyday phenomena and advocates teaching for understanding. Third International Science and Mathematic Study data show American and German teachers' interest in procedures and algorithms, compared with…

In literature on problem-based learning (PBL), it is often difficult to determine whether the educational approach being described is actually PBL. Provides planners and assessors of PBL curricula with a framework for analysis. Educational activities can be categorized as PBL according to three core principles and four criteria concerning their…

This study examined the writing strategies and text characteristics associated with discovering a scientific principle by writing about an experiment. Sixty-four university students (non-science majors) carried out a physics experiment concerning either buoyancy, or the forces acting on a balance scale, then wrote an informal journal-style note…

This document describes how to teach a computer to add numbers using the LOGO programing language. The programing project is described in the way a student might develop it. The model of developing the program uses humans as an anthropomorphic model for the computer, and the computer as a model for people. The document has an unorthodox style, as…

Activities originally designed to teach third-grade students about measuring liquids are presented. Included in the document are reasons to teach students how to use the basic units of liquid measurement and the development of a "laboratory" within the classroom where pupils could work while minimizing the mess. Some of the topics developed for…

This book introduces third through sixth grade teachers to problem-based learning (PBL), a system for classroom instruction and curriculum development. It combines the PBL system with practice in locating, evaluating, and thinking about information from the Internet. It provides 8 PBL units for use in the classroom, offering instructions for…

Presents a series of lessons that extend the concrete experiences many elementary students have had with attribute blocks to provide middle school students with informal opportunities to explore the concepts and properties of relations and functions. (DDR)

Evaluation of a sequenced inquiry learning task with 20 normally achieving junior high students, 18 students with learning disabilities (LD), and 16 with mild mental retardation (MR) found 75 percent of the normal, 50 percent of the LD, but none of the MR students made the correct induction. LD and MR students were less likely to answer…

This article describes a project that involved two groups of able students (ages 11-14) identified by teachers to work on problems set by two local industries. The project was designed to enrich the curriculum by developing problem solving skills and understanding of the application of science and technology in industry. (CR)

Three general areas in which technology (microcomputers and video technology) can facilitate learning are discussed: (1) helping students develop fluency (rapid recognition of familiar patterns); (2) providing rich problem-solving contexts that invite thinking; and (3) enabling students to create products that catch the attention of their teachers…

Describes teaching methods employed in German elementary school classrooms that develop discovery, creativity, and a spirit of cooperation in students learning mathematics. Methods included free choice of learning activities by students and small group cooperative activities. Students' motivation, self-confidence, social and communications skills,…

Demonstrates how the uniqueness and anonymity of a student's Social Security number can be utilized to create individualized polynomial equations that students can investigate using computers or graphing calculators. Students write reports of their efforts to find and classify all real roots of their equation. (MDH)

Describes the construction of durable, inexpensive and large sand-hourglasses for use in controlled experiments that allow students to observe, infer, measure, record data, and predict. This hands-on activity is designed to take place over a three-day interval. Includes materials needed, techniques, procedures, follow-up activities, and resource…

Presented are three methods to enrich the mathematics classroom. The first introduces an activity allowing students to discover the law of sines. The second gives eight distance-rate-time problems of value for their counterintuitive or elegant solutions. The third poses multiple answer questions that promote student interaction and communication.…
