An approach to teaching grammar concepts treats conceptualization as a process of sensitization, consisting of three stages: motivating the student to learn the concept, presenting the operating concept and the grammatical category in question, and consolidating and enriching the concept in the student's mind. (MSE)

Discusses some of the ways that some scientific concepts evolve and are perpetuated, even if they are not completely accurate. Uses the example of groundwater, citing numerous ways that various people understand it and, in many cases, form misconceptions. (TW)

Presents an ethnographic study of whether a heterogeneous group of Sotho people in Southern Africa continues to subscribe to a particular cultural metaphor concerning heat, even though the group is no longer strictly traditional in its way of life. Considers implications of the metaphor's persistence for the learning of orthodox scientific…

A brief overview is given of a research project funded to investigate the cause and cure of errors in ratio and proportion, algebra, and fractions. Choosing pertinent information, interviewing students, listing significant features, developing lessons, and testing the materials are considered. (MNS)

Reports that students frequently confuse meanings of terms and misunderstand function-related concepts. Also, providing mental images of functions is often limited to elementary algebra examples. This article describes a game which can help create conceptual links between the function properties and their various representations. (PK)

The author suggests that, through using the outlined question model and suggested classroom activities, elementary students will improve their abilities to analyze routine, one-step word problems and make a plan for the solution. It is further argued that the same algorithm can be applied to multistep problems by using specified questions. (PK)

During the first 12 weeks of an applied calculus course, two classes of college students studied calculus concepts using graphical and symbol-manipulation computer programs to perform routine manipulations. Three weeks were spent on skill development. Students showed better understanding of concepts and performed almost as well on routine skills.…

Reported are compulsory education pupils' representations of electric current in a constructivist approach to introducing direct current (DC) circuits. Suggests that the pupils views can be modelled after an energy framework. Makes suggestions about the content, the apparatus and the experiments used in teaching DC circuits. (CW)

Suggests that problem-solving extensions are appropriate experiences for differentiating learning experiences for students with high abilities. The extensions fall into four major categories: pattern and generalization, new concepts and vocabulary, creativity, and making value judgments. (PK)

Discusses the use of analogies and models for teaching about electric current. Reports on a study in which one group of students used analogies to learn about electric current and one did not. Results indicate that, in this case, analogies did not play a significant role in student understanding. (TW)

Reports on a study designed to examine students' understanding of certain aspects of heat, pressure, and evolution. Results indicated that little change was apparent over the two-year period of the study, with most of the students in the 12 to 14 age range at the same conceptual level as the 14 to 16 year olds. (TW)

Findings from relevant research applying Piaget's theory to mental retardation, psychosis, and autism are reviewed. Many autistic individuals show an arrest in operative functions at the sensorimotor functions. The early arrest interferes with subsequent development of higher-level conceptual, symbolic, and social skills. (Author)

Investigates the role of intraverbal learning (a process through which semantic knowledge is acquired from purely linguistic information) in preschool children's acquisition of semantic concepts. Shows that the relative effectiveness of pictorial and intraverbal information depends on the child's age, the type of information supplied, and the…

Offers perspectives on how conceptual changes actually take place in students. Proposes that elements of Kuhn's concept of scientific paradigms and Wittgenstein's concept of the "language-game" be considered in an analysis of conceptual change. Explains how components of these models relate to science learning. (ML)

A collection of student distortions, represented by student-invented variations of theorems, are presented. They were drawn from examination papers of 17-year-old students in Israel. (MNS)
