The use and analysis of student generated propositions linking two scientific concepts (photosynthesis and respiration) were examined before and after the study of photosynthesis. A proposition-generating task (PGT) was used as a diagnostic tool to indicate student misconceptions and partial understandings. Focus was on determining: how the nature…

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' (N=39) ideas on the concept of "animal." Data were…

The aim of this study was to incorporate a web-assisted program to normal traditional classroom instruction and study about students' misconceptions in force and motion concepts in physics. The Web-based physics program was incorporated with the traditional lecture. Specifically, 30% of class time was allocated for using this tutorial program, and…

This article describes the rationale for and development of a computer-based instrument that helps identify commonly held science misconceptions. The instrument, known as the Science Beliefs Test, is a 47-item instrument that targets topics in chemistry, physics, biology, earth science, and astronomy. The use of an online data collection system…

These item specifications were developed as a part of the Arkansas "Minimum Performance Testing Program" (MPT). There is one item specification for each instructional objective included in the MPT. The purpose of an item specification is to provide an overview of the general content and format of test items used to measure an…

This paper examines the preprint as a medium of information in the communication process among scientists. The proliferation of scientific research since World War II has increased the prevalence of preprints as a means of coping with the volume of science literature worldwide. This project collected data via a search of publications during the…

It is often both possible and valuable for a teacher to be a researcher in his or her own classroom. This paper describes the nature of cognitive research and focuses on two areas of research that may be of special interest to classroom physics teachers. The first area refers to misconceptions that students bring with them to their physics…

This unit consists of four parts. Part 1 contains a five-item instrument designed to help teachers clarify their own views about "burning." Part 2 discusses scientists' views about burning and lists answers to the survey instrument presented in part 1. Part 3 contrasts scientists' views with children's views, using children's comments…

Objectives, topics/understandings to be taught, and teachers notes are provided for the seven units in this Regents biology syllabus. Units and major topic areas include: (1) unity and diversity among living things (concept of life, diversity/unity of life); (2) maintenance in living things (nutrition, transport, respiration, excretion,…

There has been a marked increase in recent years in research studies of the alternative "frameworks of thought" that learners bring to the interpretation of what they meet in school science. Provided are summaries of papers and discussions from a meeting which critically reviewed the methods being used in such research and their…

This paper is a summary of much of the available research on college science laboratory instruction of the past decade with a focus on the effects of specific laboratory teaching strategies upon student learning outcomes. Some tentative interpretations from a review of the literature found are: (1) inquiry or investigative approaches in college…

The Test of Integrated Process Skills (TIPS) was administered to 667 students in grades 9-12 who were registering to participate in a regional science Olympiad on a southern university campus in February 1988. Each student's score on the test was correlated with subsequent performance in one or more of the 11 Olympiad events. Of the 667 students…

This is one of five panel reports that have been prepared as part of the first phase of Project 2061, a long-term, multipurpose undertaking of the American Association for the Advancement of Science designed to help reform science, mathematics, and technology education in the United States. Major sections included are: (1) "Rationale";…

Trying to change the predictive rule for the sinking and floating phenomena, students have a great difficulty in understanding density and they are insensitive to empirical counter-examples designed to challenge their own rule. The purpose of this study is to examine the process whereby students from sixth and seventh grades relinquish their…

The Institute in Physical Science was developed to address the need for updated information and training in physics, chemistry, and technology among teachers of physical science. Five major objectives addressed were to: (1) improve physical science teachers' understanding of fundamental concepts in physics and chemistry; (2) provide physical…
