Mathematics instruction can be approached as a cognitive skill, as illustrated by these elementary-level classroom activities. (LH)

The efficacy of teaching higher level cognitive skills to the trainable mentally retarded is questioned as research has yet to show that the skills learned can be generalized by this population to the classroom or other settings. (Author/PHR)

The association of locus of cerebral hemispheric specialization of spatial function with identity and equivalence conservation judgments was tested in a group of four- to six-year-old right-handed children (N=31). (Author/MP)

The specialized regions of the brain which control mental activity and language development are discussed in this article. (Author/SA)

Discusses issues related to the development of only children v children raised in large families. (CM)

This study, conducted with seventh graders, lends support to the Piagetian hypothesis that the development of formal operations is a prerequisite for the effective learning of the proportions concept. (MK)

Suggests secondary parasuicide prevention is the most viable path for future research. Aggressive case findings and primary prevention approaches have failed to reduce suicide attempt rates. A secondary prevention model, based on factors predictive of parasuicide, was developed. Stress reduction and cognitive restructuring were primary goals of…

Describes a general chemistry course taught at Xavier University (Louisiana), designed for both well-prepared and educationally disadvantaged students. Lists course materials, outlines course structure, identifies 12 aspects of course content, and discusses student evaluation. (JM)

An eight-phase model of processes involved in mathematics problem solving is presented. At each phase, results from factor-analytic studies are used to suggest abilities relevant and prerequisite for successful completion of the phase. Presentation of the model is followed by a discussion of implications for teaching and research. (Author/MK)

Reports that spatial ability was unrelated to formal reasoning task performance. Notes that sex differences occurred with balance tasks and pendulum tasks, suggesting male superiority at manifesting proportionality and isolating variables. (Author/RL)

Explains how the instrumental enrichment program helps adolescents and adults develop higher order thinking and problem-solving abilities. (Author/MLF)

Twenty-seven suicidal, aggressive, or normal children (ages 10 to 12) were administered the subtest of similarities from the Wechsler Intelligence Scale for Children, a questionnaire to assess the concept of death, and a questionnaire to assess the concept of life. Results favor assumption that distortions in the death concept are specific and,…

Cognitive consequences of play and exploration were examined by assigning 36 economically disadvantaged preschoolers to one of three treatment conditions: sociodramatic play training, exploration training, and free-play control. (MP)

A comparative study of conservation development in partially sighted, sighted, and sighted blindfolded children at four age levels was assessed. Conservation on tasks of mass, weight, and volume were evaluated using Piaget and Inhelder's prediction, judgment, and explanation questions. The significant differences were found between groups, task,…
