The need for developing a geometry curriculum sequence is discussed. Work by a group of about 50 mathematics educators on intuitive aspects of Euclidean classifications and relations is presented. Textbooks were analyzed, a sequence of concept clusters developed, and a scope-and-sequence chart included. (MNS)

Designed to determine a reader's ability in processing information relationships in written discourse in English, the extended-cloze instrument consists of six reading passages, each with four complete sentences deleted. Students read each passage and select the best of four multiple choice alternative sentences for each deletion. The instrument…

Describes and evaluates several fiction classification systems from the perspective of how well they answer likely reader queries regarding subjects of novels, and their utility for browsing. The usefulness of subject headings for card catalogs and print and online indexes to enhance topical access to fiction is discussed. (Author/MBR)

Presents the hierarchical structure of quadrilaterals as an illustration of learning a geometric concept by moving from the levels of visualization and analysis to the level of formal deduction. The development discusses the classification of quadrilaterals, the inheritance of properties within the hierarchy, connections between algebra and…
