This study was designed to investigate the effects of a dynamic instructional environment, English proficiency, and visualization level, independently and interactively, on middle school students' construction of the concepts of reflection and rotation. The effects of a dynamic instructional environment and English proficiency on students' two-…

The process of students' conceptual change was evaluated during a computer-supported physics unit in a Grade 10 science class. Computer simulation programs were developed to confront students' alternative conceptions in mechanics. A conceptual test was administered as pre-, post-, and delayed post-tests to determine students' conceptual change.…

The primary purpose of this study was to understand what happens when some aspects of the constructivist approach, namely prediction, explanation, student-centered, and teacher-centered discussions, are applied to science teaching. The study involved 363 junior high school students in Taiwan. It combined the effectiveness of four alternative…

This book is based on the premise that students apply thinking skills to learning science concepts by doing through firsthand experiences in an interactive, open atmosphere; constructing by building knowledge through guided inquiry; and connecting by relating learning to the world around them. The contents of this book have been designed to…

Incident identification graphs can be used to diagnose areas of difficulty in a subject's problem-solving schema at the episodic level. In this study, 22 subjects (2 experts and 20 novices) categorized into five problem-solving groups (expert, high algorithmic/high conceptual, low algorithmic/high conceptual, high algorithmic/low conceptual, and…

Schematism is proposed as part of an epistemological framework for constructing and employing scientific knowledge. Within this framework, it is proposed that a concept of physics can be explicitly defined in a scientific theory by a schema that includes: (1) the domain of the concept; (2) its organization, i.e., the relationships between this…

In the past decade, research on students' ideas has drawn attention to underestimated problems of learning physics. This also particularly applies to Science/Technology/Society teaching. Proposed solutions are mainly inspired by a constructivist cognitive science perspective and are formulated as general teaching strategies that aim at a process…

The thoughts that teachers have about the content and students they are to teach influences the way in which they will teach. This article briefly discusses the literature on teacher thinking with particular reference to recent work in science education to provide a framework in which to situate the research. The article describes the interview…

These American Indian standards for science education were developed in close alignment with the 1995 "National Science Education Standards," but tailored specifically for use in schools serving American Indian students. This document applies most of the science concepts of the U.S. national standards to American Indian life and issues,…

The purpose of this paper is to test three hypotheses about background knowledge that arise from the literature of cognitive psychology. The data base consists of the matrices of correlation coefficients that have been accumulated as part of an ongoing meta-analysis of factors influencing attitude and achievement in science. A search of the…

Eighteen high school science students were involved in a study to determine what attributes in the problem statement they need when representing a typical osmosis problem. In order to realize this goal students were asked to solve problems aloud and to explain their answers. Included as a part of the results are the attributes that the students…

Rockets have evolved from simple tubes filled with black powder into mighty vehicles capable of launching a spacecraft out into the galaxy. The guide begins with background information sections on the history of rocketry, scientific principles, and practical rocketry. The sections on scientific principles and practical rocketry are based on Isaac…

A learning cycle consists of three phases: exploration; conceptual invention; and expansion of an idea. These phases parallel Piaget's functioning model of assimilation, disequilibrium and accommodation, and organization respectively. The learning cycle perceives students as actors rather than reactors to the environment. Inherent in that…

Undergraduates from chemical engineering, applied chemistry, and environmental science courses, together with first-year postgraduate research students in electrochemical technology, are provided with an experiment that demonstrates the reduction of dissolved oxygen in aerated seawater at 25°C. Oxygen reduction is examined using linear sweep…

This article describes an exploration into improving the process and the outcome of learning in interactive teaching at the first-year university physics level, using what is becoming widely known as the "variation approach to learning." To explore this approach we chose an area of mechanics that is widely known to pose learning…
