Examined was the attainment of projective spatial concepts of third-, sixth-, and ninth-grade students. Eight Piagetian-type tasks were developed to provide evidence for Piaget's model of groupings of mental structures dealing with time and space. Task performance among grade levels and gender was examined. (CS)

Described is a study that confirms positive effects on student achievement of manipulation of molecular models by high school chemistry students over a long period of time. Also examined but unanswered were questions regarding applications of Piaget's theories in determining differential effects for concrete and formal operational students. (CS)

The investigation reported pursued the possibility of cross-cultural differences between American and Swiss children in terms of how they perceive and conceptualize spatial figures. There was statistical evidence that the preferences of American and Swiss children were different when compared as a whole or by sex and test version. (MK)

In a small experiment, normal and educationally subnormal primary children had no difficulty making negative referential descriptions in natural contexts, when their attention was drawn to the context by the experimenter. Awareness of context related to mental maturity, and there was a developmental trend in descriptive forms. (Author/SJL)

Examined the development of communicative competence in deaf children and its interactions with use of communicative gestures and/or words. Data indicated (1) the use of communicative gestures increased with age while speech remained constant; and (2) the number of gestures used correlated with communicative accuracy. Difficulty level influenced…

Examined judgments of intolerance given by children, adolescents, and adults toward disagreeing others. The evidence suggested that intolerance may be a lower level of reasoning in a social cognitive developmental progression. (Author/DB)

Describes an activity center where students work independently on problem-solving tasks. Participants keep records of their work and share ideas of activities with the class. Includes a list of tasks for the activity center. (MA)

Presents results of the 1976 workshop organized by the European Communities' Biologists' Association (ECBA) in Amsterdam. Recommendations on university training of European biologists prior to specialization are included. (HM)

Remarks directed to Peter Augustine Lawler and an earlier article are presented. The rationale for a program of philosophy for children developed at Montclair State College is compared with Roland Garrett's conception of philosophy. Distortions in Lawler's perception of current philosophical practice and teaching are indicated. (MLW)

Examined one-year follow-up data on a cognitive-behavioral treatment. Improvements were found for subjects in all treatment groups, and these effects were attributed to increased age. Results indicated that conceptually trained children showed significantly better recall of the material than either concrete trained or control group children.…

The label "cognitive" has been used to designate five substantially different approaches to the study of learning disabilities: information processing, metacognition, genetic epistemology, cognitive behavior modification, and the specific abilities model. (Author)

The use of symbols in the play of young children during the preoperational period of cognitive development provides the foundation in representation that will be needed later when using higher abstract forms such as written words. (JN)

Recent findings related to neurological research include: (1) the Proster Theory implies that the brain works by sets of programs or prosters; (2) the Brain Growth Spurts theory defines the growth of the brain in spurts with cycles of rest; and (3) in the Hemispheric Specialization Theory, the left and right hemispheres of the brain have specific…

A prereading strategy designed to predict events and provide practice in answering questions requiring inferences between text and prior knowledge were used with elementary school students. The performance of experimental groups surpassed that of the control groups on some measures while results were mixed on other measures. (MKM)

Research Studies reveal that the development of native language proficiency and full bilingualism enhances rather than impedes the education and personal development of minority children. Teachers of language and all subjects should cooperate in promoting native language proficiency and encouraging its use at home. (PMJ)
