Three studies examined the development of category-based induction using an induction then recognition (ITR) procedure in which participants make category-based predictions about study items and are then given a surprise recognition test that requires discrimination between old and new category members. Exposure duration for study items was either…

The development of the ability to use taxonomic, phonemic and sense impression categories as dimensions of encoding was investigated using third and fifth graders and college students. (ED)

The hypothesis that overall-similarity relations structure both adults' and children's classifications of heterogeneous objects (objects that differ in a variety of ways) was supported in two experiments. When objects varied simultaneously on many dimensions, adults and children constructed classifications that maximized within-category similarity…

Two implications of best-example theory for category acquisition were tested using a set of artificial concrete object categories. Categories acquired from initial exposure to good exemplars were learned more easily and accurately. People learn the best exemplars are category members before learning the poor exemplars are category members.…

Investigates the influence of logical skills (inclusion and seriation) on the degree and kind of semantic integration performed on remembered material among 47 third- and fourth-grade boys and girls and college students. (JMB)

Hoffman's (1975) theory holds that altruism is based on cognitive development and mechanisms for empathic distress present from birth, with the individual going through stages of personal distress, empathic concern, and perspective taking. The Davis Interpersonal Reactivity Index (IRI), a measure of empathy, contains four subscales: personal…

William Perry's description of college students' stages of cognitive development is condensed into four classification categories, which are explained and told in an animal allegory. This presentation clarifies the theory for teacher use. (MSE)

Presented is a simple, unified approach to chemical nomenclature which employs the distinction between the terms chemical substance and chemical species. The classification of matter and chemical nomenclature are used as examples to illustrate this scheme. (CW)

Described in this study are student teachers' frameworks of purity and the related concepts of the states of matter. The concept of natural versus pure substances, classifying states of matter, and implications for teaching drawn from the results are discussed. (Author/KR)

Studied the way in which 32 preschoolers aged three-five years, 28 second-graders and 64 undergraduates generalized from a labeled exemplar to other potential members of the same category. Results indicated that preschoolers focused mostly on single attributes in making category decisions and older individuals primarily exhibited multiple…

Analysis of statements by 869 students and 21 faculty at Queensland University of Technology (Australia) concerning learning, using the SOLO (structure of observed learning outcomes) Taxonomy, identified key concepts in learning in eight categories: learning definitions; factors influencing learning; learning strategies; learning styles; aspects…

A study was conducted to test the hypothesis that metaphorical thought develops according to the principles governing other categorizing processes. Of particular interest were the questions of whether preschool children possess the categorical flexibility to comprehend metaphorical statements and, if they do, whether this flexibility manifests…

Discusses the use of writing to enhance learning in mathematics from a conceptual development perspective. Shuell's phases of learning are described as a general model for conceptual development and subsequently matched with Britton's categories for transactional-informative writing. Sample mathematics assignments for each writing category are…

Laurie Richlin has been running a workshop on course design for higher education for over fifteen years, modifying and improving it progressively from the feedback of participants, and from what they in turn have taught her. Her goals are to enable participants to appropriately select teaching strategies, to design and create the conditions and…
