Investigates whether viewers of different ages are aware that camera lenses manipulate the apparent velocity and distance of events presented on television. Suggests that younger viewers do not understand how television production techniques manipulate perceptual information and may thus be misled by their use. (PD)

The ability to perceive and understand that liquid remains invariantly horizontal was studied with 64 hearing impaired junior and senior high school students. Significant results were found for training on the most difficult bottle positions. No differences in performance were found between the male and female hearing impaired students.…

Describes a series of laboratory experiments designed to provide concrete experiences with advanced inorganic chemistry lecture topics. Stresses student invention of chemical relationships and periodicity according to physical properties and reaction type. Includes comments on student performance and attitudes toward the experiments. (JM)

The frequency and type of inappropriate word extensions (i.e., use of ball for moon) in the spontaneous speech of nine young language disordered children (2.8 to 3.4 years old) were studied. The percentage of inappropriate word extensions of these children was comparable to that of normal children at the same level of linguistic development.…

Delineates Sigmund Freud's theories of symbolic relations, Jean Piaget's theories of cognitive development, and Eric Erickson's concept of identity crisis to analyze and explain the characteristics and phenomena of adolescent development. Suggests roles and tasks for teachers and parents in promoting healthy development. (WL)

Research indicates that teachers have different job skills, knowledge, behavior, and attitudes at different points in their careers. As their needs, goals, and experiences change, different staff development activities are required. Tables show stages in teachers' careers and corresponding strategies for supervision. (PP)

Lawrence Kohlberg's empirical research does not, in itself, justify the claim that his higher stages of moral development are more adequately moral than lower stages; consequently, using Kohlbergian interventions to promote student development through these stages is unjustified. Empirical research, while necessary for planning and executing…

This study investigated whether a pattern for the development of motor ability could be discerned, using the same range of motor performance tests with boys and girls at 10 different age levels. Researchers did not find a pattern as clear as has emerged in personality and intelligence development. (PP)

Investigated development of propositional logic and three formal logical schemata (underlying generic problem solving processes/operations) in adults (N=59) enrolled in their second year of medical school. Two students were formal on the 12-Piagetian tasks used, and the 57 remaining were classified as transitional formal. Implications are…

A linear regression model was used to test the relationship between the knowledge of Kohlberg's theory and moral stage development. A multiple regression analysis was used to test the multivariate relationship between one dependent and five independent variables. Neither analysis demonstrated a statistically significant relationship. (Author/PN)

A paper-and-pencil test of seven of Inhelder and Piaget's formal operational schemes was developed. Multitrait-multimethod cross-validation procedures indicated that the objective test is a valid and reliable measure. It has the advantage of use in a large group setting without the need for trained clinical interviewers. (Author/PN)

Illustrates how children handle conflict and adjust to one another when their goals are incompatible. Found clear developmental trends: with increasing age, children used more compliance-gaining strategies; their compliance-gaining strategies became more adaptive; and their conflict episodes became more complex. (PD)

Tests a career model of immigrants with the following stages: crystallization, vocational retraining, job entry and trial, establishment, and maintenance. Two samples of immigrants are followed up. The research brought into focus the continuity of the process of career reconstruction after the interruption of vocational activity caused by…

In describing the just community approach to moral education developed at Cluster alternative high school, the author focuses on the setting of collective norms and relationships between these norms and Kohlberg's moral development stages. He finds this approach to moral education to be more comprehensive than the moral discussion approach. (SJL)

Learning, beginning in infancy, depends chiefly upon the nature and quality of movement experiences. Since 50 percent of a child's potential for learning is developed by age five, it is essential that movement programs be devised for children of preschool age. Movement programs must be geared to the individual child's developmental level. (JN)
