Effects of author-generated and learner-generated elaborations on subjects' abilities to recall, classify, and apply conceptual knowledge were compared for 94 college undergraduates studying a passage on psychological concepts. Author-generated elaborations and specific elaboration activities produced superior effects in comparison with…

Introduced is a sandstone classification scheme intended for use with thin-sections and hand specimens. Detailed is a step-by-step classification scheme. A graphic presentation of the scheme is presented. This method is compared with other existing schemes. (CW)

Presented is an activity designed to teach the use of the scientific method to non-science majors. Collecting, classification, and follow-up activities for a beach trip are discussed. Two simple dichotomous keys are included. (CW)

Discussed are some of the issues which were considered when the International Union of Pure and Applied Chemistry revised its guide to notation in physical chemistry. Included are the choice between SI and non-SI units and choosing sensible names and symbols for quantities. (CW)

Described is the sequence of topics, learning activities, materials and demonstrations for the course. It is stressed that students can learn these skills in less than 30 hours of instruction. (CW)

This study organizes items from seven behavior rating instruments into as few behavior clusters as possible. Methods used include card sort activities and a panel of experts examining items to establish their subgroup placement. Findings indicate a method for organizing behavior descriptors into clearly defined subgroupings and unifying behavior…

Discussed are the substructures (subgraphs) of imaginary transition structures that provide an effective approach to the characterization of organic reactions. A comparison of conventional methods and this method is presented. (CW)

Describes a teaching strategy--word sorting--that helps students to develop more accurate and automatized word recognition and spelling ability. Describes a series of word categorization activities in which students compare and contrast various word features or properties. (MG)

A study of high school choice programs in four large cities (New York, Chicago, Philadelphia, and Boston) shows that meaningful school choice is beyond the reach of the most vulnerable innercity students. Educators considering such plans must recognize the dangers (like stacked admissions policies) raised for these youth. (MLH)

Argues that regionalization is a scientific classification of the earth's surface and crucial to the study of geography. Identifies seven key concepts which are associated solely with regionalization. Suggests a method for introducing the concepts in the classroom. (KO)

Three studies explored the effects of grouping versus randomized items in questionnaires on internal consistency and test-retest reliability with samples of 80, 80, and 100, respectively, university students and undergraduates. The 2 correlational and 1 experimental studies were reasonably consistent in demonstrating that neither format was…

Recommends a revision of the traditional method for teaching history, so that students view facts as the starting point, from which they learn to classify, examine, and evaluate historical events. Suggests activities and projects for implementation of this teaching method. (LS)

Argues that collection development systems need to exert greater control over scholarly and educational information if the systems are to adapt to changing technical and economic conditions. Steps toward increased control should include categorization of sources and access by function, ongoing definition of a title-specific core, and the…

Outlines a suggested scheme for introducing young children to the subject of classification by using pets and an investigatory approach. General objectives and introductory, developmental and culminating activities are provided. (Author/CW)

A study of 373 students with suspected learning disabilities found that different measures for calculating discrepancies between aptitude and achievement and for measuring achievement resulted in relatively little agreement on appropriate classification. A second study, using computer-simulated data, provided a framework for generalizations to a…
