Describes a study which was designed to determine the effect of a 25-hour introductory qualitative analysis course on high school students' understanding of formal concepts related to electrolytes. Suggests that introductory concrete experiences better prepare students to deal with more formal abstract concepts. (TW)

The major purpose of this book is to rejuvenate the focus on thinking throughout the curriculum. This collection of 85 essays is intended to help educational leaders--teachers, administrators, curriculum workers, staff developers, and teacher educators--infuse curriculum, instruction, and school organization with practices that more fully develop…

Research developments in cognitive psychology, and their implications for teaching and learning at the level of professional education, are summarized. Areas discussed include organization of long-term memory, influences on storage and retrieval from memory, problem solving and transfer/use of analogy, concept formation/categorization/pattern…

Thirty-six Korean first graders were interviewed to study their ability solving addition problems with sums of 10, single-digit sums between 10 and 18, and subtraction problems with minuends between 10 and 18. Finger methods to show sums over 10 and the regular named-10 Korean number words supported their learning of 3 efficient recomposition…

Discussed is how the concept of equivalence can relate various segments of a mathematics program and help students develop an appreciation of the unity of mathematics. Activities and examples of equivalence at all grade levels are included. (KR)

Discusses and provides sample lessons of learning by discovery and weekly problem sets, which are presented as alternative methods for teaching college calculus. Both approaches stress conceptual understanding and guide the students to explore the ideas of calculus in small groups in a computer laboratory setting. (JJK)

Asserts that promotion of classroom thinking generally is assumed to be the sole responsibility of the teacher. Suggests using a text that portrays students engaged in reasoning and other interventions to stimulate the growth of critical and creative thinking. (CFR)

Described is the Educational Leaders in Mathematics (ELM) Project, a four-stage inservice teacher program designed to stimulate teachers' development of a constructivist view of learning. The impact of the intervention was studied, and results indicated that teachers' beliefs were affected, producing changes in teaching strategies. (MDH)

Attempts to express a group of children's understanding of inversion, retrograde, and retrograde-inversion as it applies to musical composition and color schemes. The children, ages six to nine, displayed idiosyncratic approaches to the problems. Discusses the possible implications for symbolic language and cognitive development. (MJP)

Math can help children understand and think about the many aspects of their world through its connections to them. Teachers who see, and help children see, those connections enrich children's learning and development. Teachers know that building children's vocabularies helps them understand stories they hear and later will read. But by taking a…

This paper argues that operations with negative numbers should be taught using a curriculum that is grounded in algebraic geometry. This position is supported by the results from a study that compared the conceptual understanding of grade 9 students who received the Algebra Project transition curriculum to a control group of grade 6 gifted…

A quantitative synthesis of multivariate studies in science education during the past ten years yields evidence to support a model of achievement in science very much like that currently proposed in the literature of expert problem-solving. Despite previous claims, spatial visualization and verbal ability predict additional variance in achievement…

The purpose of this descriptive study was to create and test questions on stoichiometry with number ratios for quick mental calculations and to identify students' problem-solving strategies. The present study was a component of a more comprehensive investigation in which 7,441 German senior high school students were asked to work on 154 test items…

The program and abstracts of the presentations of the 1991 meeting of the Society for College Science Teachers are the topics of this report. Society officers are listed, a history of the society is provided, and membership information is given. The presentations reflect different topics in the teaching of college science. The abstracts of…

This paper reports on the evaluation of an 11-week curriculum created to foster seventh grade students' understanding of scientific modeling. In the curriculum, students engaged in model-oriented activities such as creating non-Newtonian computer microworlds to embody their conceptual models, evaluating their models with criteria, and reflecting…
