Presented are several consequences of Ceva's theorem which deal with ratios of segments formed when a parallel to one of the sides is drawn through the point of concurrency. The proofs of these theorems are included and are of varying degrees of difficulty. (KR)

Examines the relationship between pupil characteristics of income, gender, chronological age, and level of cognitive development and selected domain-specific skills in mathematics. Results show mathematics performance as a function of the quality of thinking. Teaching to cognitive developmental level requires an individualized approach to…

Nondisabled only children (N=10) were observed and videotaped at home with their mothers in scripted, free-play, and novel contexts to probe uses of temporally displaced (TD) communication and maternal contributions to its development. Scaffolded maternal speech was found important to TD speech development and context-sensitivity underscored as a…

Classroom assessment procedures of 36 teachers in grades 2 to 12 were studied to determine the extent to which they measure students' higher order thinking skills in mathematics, science, social studies, and language arts. A striking finding was the absence of evaluation of comparative and evaluative thinking. (SLD)

Discussed are ways in which students can generalize both quadratic or cubic situations. Generalizations are produced using the factor method, repeated linear generalizations, means of the mean, and through the use of differences. (KR)

Reports on a study investigating the effects of conceptual models (computer graphics and animation) on learning and transfer of code evaluation and generation skills of novice programmers; changes in declarative knowledge during skill acquisition; relationships between the quality of subjects' mental models and performance in skill learning and…

Reports on a study of the impact of cooperative learning techniques, compared with traditional Navy instructional methods, on Navy air traffic controller trainees. Finds that cooperative learning methods improved higher level reasoning skills and resulted in no failures among the trainees. (CFR)

Maintains that U.S. history did not begin with the colonization of North America by Europeans but with the Native American tribes that flourished prior to colonization. Discusses economic issues that determined the history and culture of various tribes. Provides a lesson plan based on economic decisions made by the Choctaw tribe. (CFR)

Reviewed 12 currently available mathematics assessment tools to determine whether they would be appropriate for use in a college-level mathematics clinic. Tests were assigned to two domains: cognitive and mathematical content. Major deficiencies of the tests are cited. (Contains 15 references.) (MDH)

Examines perceptions of eighth graders in a science teaching environment in which they guide their own learning, frame problems for inquiry, design data collection procedures, and interpret and present data in a convincing fashion. Asserts that, in constructing their inquiries, students successfully negotiated courses of action and established…

This study investigated what teachers understood from reading, writing, and discussing a case versus just reading and writing. Analyses of writing and oral discourse from student, beginning, and experienced teachers indicated that the addition of discussion affected their thinking about the case, benefiting teachers at different experience levels…

Changes in verbal, spatial, and reasoning intelligence among Swedish 13-year olds were studied from 1960 to 1990. Rising verbal scores until 1980 have been followed by a decline to essentially the 1960 level. Spatial and reasoning results have risen continuously. Gender and social class differences are discussed. (SLD)

Contends that an interdisciplinary curriculum and cooperative learning are well suited to middle school students. Asserts that the approaches help students learn higher order thinking skills and improve social skills. Maintains that authentic or performance-based assessment is appropriate for these techniques and this age group. (CFR)

Continues an article from an earlier issue that reported on a study of memorable social studies activities experienced by college students when they were in elementary schools. Finds that activity-oriented instruction was remembered most positively. (CFR)

Reviews the computer simulation, "Civilization," and asserts that it offers exciting possibilities as an interactive introduction to world history and historical thinking. Includes a course syllabus in which "Civilization" serves as a central feature and two writing assignments based on the simulation. (CFR)
