In this Appendix, we provide details about the data used for the current study, the curricula used in the classrooms from which data were collected, and the current study's methodological approach. (Contains 14 tables and 5 footnotes.)[For full report, see ED544189.]

Investigates the developmental sequence of learning to transform objects into agents and recipients of action in early symbolic play. Each of 48 children (from 14 to 25 months old) demonstrated initiative pretending after an adult modeled agent and recipient substitutions in pretending to talk on the telephone. (Author/CB)

Investigates (1) whether differences between boys and girls indicated by teacher rating were similar to those indicated by direct observation and (2) whether teachers' assessments of the relative frequencies with which children show particular types of behavior agree with those obtained by direct observation.

This longitudinal study examined the effectiveness of two different assessment methodologies, low structured observation and structured elicitation tasks, to obtain communicative intents from 35 normal children at the sensorimotor stage of development (9-24 months). The two approaches appeared to vary depending on the age of the child and the…

Examines groups of conduct-disordered and normal children in order to (1) test the potential usefulness of observational techniques in assessing therapeutic outcomes and (2) identify possible differences between deviant children and normal peers in aggressive and prosocial behavior. (RH)

Social participation behavior of 33 2- and 3-year-old children was observed during free-play in order to identify differences between age groups as well as differences between contemporary outcomes and Parten's 1932 findings. Trained observers recorded the frequencies of play behaviors, utilizing a time sampling procedure and Parten's categories…

Describes three themes that have informed research on cognitive development in sub-Sahara Africa over the past 10 years: (1) extending the range of generalizability of Western theories; (2) interpreting the uniqueness of the African situation; and (3) deriving implications for social policy. (Author/AS)

Examines the effect of an unfamiliar peer in a situation requiring a subject's separation from mother in order to play with attractive toys. Observation of 20 children 18 months old and 20 children 30 months old revealed that peer presence facilitated initial separation for both ages, but that age differences in subsequent behaviors existed. (CB)

Systematic observations of affiliative interaction in 15 stable peer groups were conducted across three years in an urban day care center. Groups contained 193 French-speaking children ranging in age from one to six years. (Author/RH)

The effects of introducing a microcomputer into an elementary-school classroom were studied using a naturalistic paradigm. Initial questions investigated the impact of the microcomputer on children's behavior, interactions, and responses to available software; and on the teacher's role. Data were fathered through: weekly observation for 4 months;…

The primary purpose of this study was to describe the linguistic behavior exhibited by a female subject (age 2 years, 4 months) during naturally occurring social interaction with children of different ages. Verbal and nonverbal behavior were studied; of additional interest were variables influencing the emergence of linguistic behavior. Data were…

A study was conducted to investigate issues related to the development of preschool children's self-definitions of attractiveness. Research questions were (1) At what ages can children state a self-definition of attractiveness? (2) Are self-definitions temporally stable? (3) To what degree are children's self-judgments similar to judgments made of…

Results generated by peers, teachers, and unbiased observers converged in some behavioral domains and diverged in others. All three sources provided similar pictures of the relation between aggression and status, although observations of third grade boys did not yield sufficient frequencies of aggression to allow meaningful conclusions. (RH)

Provides a comprehensive meta-analysis of gender differences in aggression; offers estimates of the magnitude of differences; provides a developmental analysis of effects for all ages for which data are available; and includes a total of 143 studies. Basic techniques of meta-analysis are presented and then applied to analyze studies of gender…

The 3-year research and development project described in this paper was conducted (1) to develop new knowledge about sex equity in classroom interactions, and (2) to develop successful techniques for reducing or eliminating sex-biased interaction. Two interventions were developed to train teachers in more equitable instructional behaviors. In the…
