The North Carolina End-of-Course Testing Program was established to provide student, school, and school system information about achievement in high school courses. This report describes: (1) "Characteristics of Biology Students"; (2) "Student Performance on the Core Test"; (3) "Anticipated Final Grades and Scores on the…

The North Carolina End-of-Course Testing Program was established to provide student, school, and school system information about achievement in high school courses. This report describes: (1) "Characteristics of Chemistry Students"; (2) "Student Performance on the Core Test"; (3) "Combining Performance and Participation:…

An investigation of Ontario high school students' understanding of acids and bases with quantitative and qualitative methods revealed misconceptions. A concept map, based on the objectives of the Chemistry Curriculum Guideline, generated multiple-choice items and interview questions. The multiple-choice test was administered to 34 grade 12…

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…

This book is an outlined for the short study (1- to 2-weeks) of chronobiology, a field of science that explores the relationships between time and biological functions. It develops step-by-step the reasoning that leads to the current scientific understanding of biological rhythms. The unit can be inserted into a standard middle or high school…

This paper presents the results of an experiment which investigated elementary school children's concept of the earth's shape and the related concept of gravity. First, third, and fifth grade children were asked a series of factual, explanatory, and generative questions in an attempt to understand as clearly as possible the way they conceptualized…

This paper reports an action study of conceptual change in mechanics using an instructional strategy based on a constructivist view of learning. The aims of the study were to determine: (1) what effect the instructional strategy had on achieving conceptual change; (2) what devices or strategies students used in their attempts to understand…

Speculative philosophical methodology was used to generate ideas about ways science teachers might help students recognize and unlearn erroneous notions about science and replace them with sound new science concepts without lessening students' intellectual self-confidence or alienating their receptivity to further science learning. The research…

The North Carolina End-of-Course Testing Program was established to provide student, school, and school system information about achievement in high school courses. Approximately 83.4 percent of the 77,154 students who took the biology test were in the tenth grade. Students taking biology in the ninth grade (8.3 percent) were on an accelerated…

The objectives and design of a 3-year study of research training and supervision in biology and physics are discussed. Scientific problems arising from work on the thesis will be a focus for the postgraduate students and their supervisors. Attention will be focused on supervisors' and students' conceptions of science, subject range, research,…

This game is designed to be used in junior and senior high school science classes with the purpose of introducing quark theory to students. This material expands on atomic theory and subatomic structure. Quarks are the fundamental building blocks of protons and neutrons. The game will teach students about the standard model of elementary…

This report presents a general framework for studying the acquisition and cognitive representation of biomedical concepts and analyzing the nature and development of misconceptions. The central approach of the report is a selective and highly concentrated analysis of the true nature of clusters of complex concepts and the manner in which they are…

This unit contains six lessons on rocks for fourth graders. It describes materials, supplementary materials (including films, units, and books) schedule, unit introduction, and background information for teachers. Lessons include: (1) "Rocks Are Everywhere"; (2) "Chart Making"; (3) "Things Are Breaking Up"; (4)…

This paper compares the old and new curricula of elementary mathematics and natural science in the Republic of China. This study, as the second phase of an evaluation period, tested a sample of the students while they were in the ninth grade and compared them to students who received the old curricula during their elementary studies. The data were…
