Failures are better documented than successes in bilingual education programs. A theory is needed powerful enough to predict success while accounting for reported failures. Most important is the effect of bilingualism on cognitive development. Use of the first language should complement the second, particularly in problem solving and question…

Based on the author's educational experiences as a student and teacher at Jesuit high schools and developed within the framework of the cognitive development theories of Lawrence Kohlberg, describes six stages of moral development. Concludes with a description of teachers at six stages of professional development. (AYC)

Low birth weight preterm multiple birth infants do lag behind initially in mental and motor development, but they are equal in development with normal peers by the age of two. It was inferred that the multiple caretaking situation did not interfere with the infants' specific attachment to their mothers. (Author/RH)

Tested the hypothesis that knowledge base development is an important condition for memory development, by using young children and college students in two experiments. (Author/DB)

First-grade children's solution processes for addition and subtraction were studied. Their processes tended to represent the relationships or actions described in individual problems. (MP)

The developmental nature of the reflective concept of "word" in young children was investigated and the degree to which these developmental aspects of metalinguistic awareness correspond to levels of cognitive development as described by Piaget was studied. (HOD)

The use of cognitive entry behaviors and instructional techniques as a new avenue for researchers in science education is discussed. (JMF)

Participants in a longitudinal study, selected according to Stanford-Binet Intelligence Test scores administered in the 1930s, and their occupations, took the Wechsler Adult Intelligence Scale. Data suggest persons increase in mental abilities over time while maintaining IQ positions relative to peers. Changes in IQ are not related to occupational…

Infants were classified as high or low in differential vocal responsiveness (DVR), and tested for degree of response to stimulation by a stranger and to stimulation by their mothers. The infants' DVR classification was related to scores on the Stanford-Binet and the Illinois Test of Psycholinguistic Abilities. (Author/SS)

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)
