This document reports a project, entitled Workshop Physics, that involved the development and testing of introductory physics materials to enable instructors to abandon the traditional separation of lecture and laboratory in favor of a workshop format. The Workshop Physics courses emphasize cognitive development enhanced by direct experience and…

This document presents the results of three studies about how children interpret observations of the biological phenomena of decay. The objectives of this report were to: (1) document and compare the ideas used by elementary school children in the United Kingdom, the United States, and Canada; (2) document how these ideas changed from age 5 to 16;…

The relationship between language, thought, and concept formation has been a central issue in many studies and theoretical discussions in various domains--philosophy, psychology, anthropology, and linguistics. The relation between language and concept development can be framed as two opposing questions: (1) Does the child learn concepts first and…

A study investigated a model that takes into account the influence of conceptual, cultural, and linguistic variables in formation of verbal and nonverbal concepts in bilingual children. This triple-interaction model states that concepts are represented in three ways: (1) nonverbally as abstract categories; (2) symbolically by means of…

A study investigated changes in prospective elementary teachers' conceptions about projectile motion. The preservice teachers (enrolled in reading methods courses) were either told or not told that they were expected to teach a videotaped lesson on projectile motion. In addition, they either participated in a combined demonstration-reading or in a…

This research investigated the teaching of concrete chemical concepts and procedures to beginning chemistry students. Data were collected for this study from students enrolled in a university-level course for nonscience majors (n=171). In the topic studied, chemical bonding, four different teaching strategies were investigated: remediation of…

Students lacking formal training in physics have great difficulty predicting the paths of various projectiles. With respect to pendulum-bobs that are released from various points in a swing, a previous experiment found that empirical feedback (i.e., resultant trajectories) produced transfer-of-training to other pendular-based tasks. However, such…

This teacher's guide is part of a program of activities that help secondary-level students develop the complex thinking skills needed to succeed in science. This program can be used with current curriculum materials. It is designed to help students integrate ideas and develop concepts that demonstrate higher level thinking. A rich environment of…

The first section of this guide contains detailed instructions on how to stage a Microscopic Explorations Festival and an overview of learning station activities that can be used during such an event. The main section of this guide provides concise instructions for setting up each of the festival stations. For each station there is an overview,…

The concept maps contained in this book (for grades 7-12) span 35 topics in life science. Topics were chosen using the National Science Education Standards as a guide. The practice exercise in concept mapping is included to give students an idea of what the tasks ahead will be in content rich maps. Two levels of concept maps are included for each…

This paper presents an argument in support of "training little scientists" based on the requirements of participation in a media-laden, democratic society fraught with scientific claims and counterclaims. This leads to a framework for evaluating the effectiveness of various approaches to science education, including how they play out in practice.…

The purpose of this study was to examine the effectiveness of an analogy activity designed to overcome junior high school students' misconceptions about the microscopic views of phase change. Eighth grade students (N=80) were randomly assigned to either a control group receiving traditional teaching, or an experimental group participating in the…

This study investigates gender differences with regard to three factors of scientific literacy. The study involved students (N=772) in Grades 9 and 10. A 100-item multiple choice test based on National Science Education Standards was used to assess scientific literacy while gender differences were explored using analysis of variance procedures.…

Examining how students reconstruct stories they've heard can give insights into why students often have difficulty understanding and retaining mathematics. Behavioral psychologists refer to the phenomenon of piecing together a series of events as "chaining." This paper argues that the cognitive capacity to reconstruct a whole contextual…

Meaning constructs are aspects of a person's cultural worldview. They are those aspects that philosophers often write about as a means by which to make sense of the world. Teachers carry their worldviews and meaning constructs into the classrooms with them. Similarly to teachers, reflective teaching proponents hold meaning constructs that are…
