Scores on the Assessment of Basic Learning Abilities (ABLA), Vineland Adaptive Behavior Scales, and the Wechsler Intelligences Scale-Revised (WAIS-R) were obtained for 30 adults with mental retardation. Correlations between the Vineland domains and ABLA were all significant. No participants performing below ABLA Level 6 were testable on the…

The Analogical Reasoning Learning Test (ARLT) was developed for use with individuals with IQs lower than 55. A study involving 58 students (ages 6-19) with moderate to severe mental retardation found the internal consistency and test-retest reliability of this measure are high. Discriminant and predictive validity are satisfactory. (Contains…

Discussed are supercalculator capabilities and possible teaching implications. Included are six examples that use a supercalculator for topics that include volume, graphing, algebra, polynomials, matrices, and elementary calculus. A short review of the research on supercomputers in education and the impact they could have on the curriculum is…

Discussed are some situations students face that result in cognitive conflict, possible sources of these conflicts, and strategies which students use to resolve, remove, or circumvent them. A global account for observed systematic errors is offered based on a general problem-solving rule called the "Matching Rule." (KR)

Described is a learning activity that requires students to write a manual to explain how to apply procedures and algorithms used in mathematics. A list of possible precalculus and calculus topics that can be used in this activity is included. (KR)

Discussed is the effectiveness of using analogies in chemistry instruction. Students' mathematics anxiety, spatial visualization skill, and proportional reasoning ability were found to be important aptitudes for determining chemistry achievement. The relationship between analogs and algorithms is described. (KR)

Problem solving is defined and characteristics of good problem solvers are highlighted. The cognitive processes used in problem solving are discussed. Suggestions for methods which can be used to teach problem solving are provided. Research implications from mathematics education are listed. (CW)

Students' conceptions of the concept of force are discussed. Possible problem formats and exercises are presented. The need for many formats and variations to help students' resolve their conflicting ideas about physics concepts is stressed. (CW)

Presented are the results of a study of the effects of peer-led tutoring groups on achievement in college chemistry. Supplemental instruction was effective in increasing students' achievement in chemistry as measured by final grades in chemistry and responses to a questionnaire. (CW)

Analysis of the responses of monolingual Dutch and bilingual Turkish, Moroccan, and Surinamese children living in the Netherlands to word association and sorting tasks revealed no significant differences among the groups. Results of the study indicated that bilingualism does not affect cognitive-linguistic development. (22 references) (Author/VWL)

Three sources of variability in school achievement of children from demographically homogeneous families were identified: (1) socioeconomic status, (2) family configuration, which are direct and environmentally mediated effects of families' demographic characteristics, and (3) individual differences in the quality of the early environment. (RH)

Presented is an analysis of published research on students' conceptual development in the life sciences with the intent of providing information on the trends and content of those studies. A list of 128 references is appended. (CW)

Discusses the advantages of using discrepant events in elementary school science classrooms in terms of motivation and problem solving skills. Describes the materials, procedures, and reasons behind five discrepant activities. (YP)

Examined are some of the distinctive features of the biological sciences. Discussed are the use of models with case studies, universal principles, and alternative frameworks. (CW)

Suggests that Latin American education could be improved by the development of teaching methods which take into consideration the prevailing sociocultural patterns and their related cognitive styles. Discusses the rural environment and the urban culture of poverty relative to cognition. Considers the linkage between previous experience and…
