Indicates the shortcomings of paper-and-pencil tests. Reports the effect of an interview-and-teaching method for students who obtained correct answers by a mechanical process but lacked a conceptual foundation. Five references are listed. (YP)

Investigates high school students' understanding of the physical relationship of chromosomes and genes as expressed in their conceptual models and in their ability to manipulate the models to explain solutions to dihybrid cross problems. Describes three typical models and three students' reasoning processes. Discusses four implications. (YP)

Proposes the use of conceptualization, exploration, and higher-level problem solving in differential equations courses as a replacement for some of the traditional material that can now be delegated to the computer. (MKR)

From a study of students in 7th through 12th grade it was concluded that salient external features of the problems, as well as factors related to the solver largely influence students' responses to the problems. The theoretical framework, however, is not the most influential factor in determining students' responses to the problems. (PR)

Discussed is the type of evidence children find to be convincing using either empirical or deductive methods to justify propositions which they consider to be true. Included are the problem, research design, and the conclusion. (KR)

This paper presents a theoretical framework for investigating the role of algorithms in mathematical thinking using a combined ontological-psychological outlook. The intent is to demonstrate that the processes of learning and of problem solving incorporate an elaborate interplay between operational and structural conceptualizations of the same…

Effects of acquisition of a problem-solving model on the ability to transfer to analogous problems in different domains were studied with 210 undergraduates who solved a biology problem and a transfer problem. Beneficial effects of the problem-solving model and implications for instructional strategies are discussed. (SLD)

Proposed is a scheme for concept development in teaching the topic of energy. Levels within the scheme are described, as well as their interrelationships and their relation to the student's own world. (KR)

Suggests that disinterest in physics occurs because students and adults can apply everyday concepts to solve problems without understanding the underlying physics concepts. Proposes Wagenschein's Exemplary-genetic Method to teach physics and illustrates the method with examples taken from history. (MDH)

Young pupils find collaborative learning hard to sustain, even though it is recommended by developmental psychology and classroom intervention theories. Investigates the effect of two role attribution strategies on communication in peer groups of different gender composition in 8th grade science classes. Confirms the effectiveness of social role…

Focuses on how conceptual themes can assist students in problem solving by acting as organizing elements and guides for thinking. States that students can learn how to use important ideas to drive key questions, discern the relationships among concepts that reflect the operation of principles, and visualize a problem to clarify essential issues.…

This paper reports a study of how students may connect the limiting process inherent in the derivative to the limit of the difference quotient (LDQ) when solving problems. The data was collected mainly through task-based interviews with five eleventh grade students. It was found that the students used various kinds of limiting processes and…

This paper raises issues motivated by considering the "identity" of problem solving. This means that we are concerned with how other mathematics education topics impinge on problem solving, and with themes that naturally arise within the problem-solving agenda. We claim that some of these issues need more attention by educational research, while…

This Practice Guide is the third in a series of Institute of Education Sciences (IES) guides in education. Much of teaching is about helping students master new knowledge and skills and then helping students not to forget what they have learned. The recommendations in this practice guide are intended to provide teachers with specific strategies…

The purpose of this research study was to examine the effectiveness of problem-based learning (PBL) on eleventh grade students' understanding of "The effects of temperature, concentration and pressure on cell potential" and also their social skills. Stratified randomly selected control and experimental groups with 20 students each were used in…
