This longitudinal study videotaped six preschool children with various developmental delays, including language delays, during free play and modeling tasks, and examined whether reported parallels between symbolic play and normal language development were evidenced. Results supported previous reports, although variability across observations was…

The paper presents an analysis of aptitude-treatment interaction (ATI) as it relates to individual differences in special education. Stressed is the importance of heterogeneity of participants and interventions, of psychological interactions, and the need for applying multivariate and transactional approaches to ATI concepts.

As dropout and student disengagement rates reach alarmingly high levels, learning styles theory offers one way to expand teaching methods and curricula to reach more students. Although accommodating individual differences is appealing, nagging doubts and murky research results (detailed in a sidebar) persist. Another sidebar explores culture/style…

Educators should stop seeing self-esteem only in individualistic terms and move toward an integrated view of self and social relations. To enhance self-esteem, schools must value authentic participation, collaborative action, a problem-centered curriculum, and interdependent diversity and banish tracking, autocratic procedures, unicultural…

Ten years ago, founders of the Key School, in Indianapolis, Indiana, studied Howard Gardner's theory of multiple intelligences and applied it to curricula for gifted and talented students. Present school benefits wide range of students and boasts seven classroom generalists and numerous full-time specialists. The model stresses all seven…

Some of the methods originally used to find relationships between reliability and power associated with a single measurement are extended to difference scores. Results, based on explicit power calculations, show that augmenting the reliability of measurement by reducing error score variance can make significance tests of difference more powerful.…

Two articles discuss the controversy about the relationship between reliability and the power of significance tests in response to the discussion of Donald W. Zimmerman, Richard H. Williams, and Bruno D. Zumbo. Lloyd G. Humphreys emphasizes the differences between what statisticians can do and constraints on researchers. Zimmerman, Williams, and…

A model of the sources and consequences of mismatches between gestures and speech is presented that argues that the transitional knowledge state is the source of the mismatch and that such mismatches signal that a child is in a transitional state of concept acquisition and is ready to learn. (SLD)

Measurement and psychometric quality of the Sternberg task (S. Sternberg, 1966, 1969), a memory search task, was investigated with 78 undergraduates. Individual performance was fairly homogeneous across responses, fairly unstable over time, and fairly stable across stimulus content. Implications for individual differences research are discussed.…

Presents a theory of cognitive development that postulates a general cognitive processing system, a hypercognitive system governing self-regulation, and specialized structural systems responsible for processing different reality domains. Suggests five principles that serve as organizational pivots of developing cognition. Reports the results of…

Cognizant of individual learning differences, the Rhinebeck (New York) School District refused to settle for mandated Regents exams. Staff developed a successful exhibition program requiring all students in the 5th, 7th, 10th, and 12th grades to demonstrate their knowledge through a performance judged by using various rubrics. (MLH)

In 1992, a group of teachers, principals, and central-office administrators at a Wisconsin elementary school developed an effective differentiated teacher-supervision process. Teachers enjoy the flexibility of choosing among three options: a cooperative-clinical supervision group, a self-directed group, and a collegial professional-development…

As educators introduce new technology into a district, school, or classroom, it is important to take advantage of children's natural ability, enthusiasm, and willingness to master new skills. Certain activities such as journal writing, picture-digitizing projects, and designated student experts help place the power of technology squarely in…

Two studies investigated developmental changes, and inter-linguistic and inter-individual variations, in the expansion and composition of young French children's early lexicons. Results indicated that lexical productivity strongly increased with age, whereas lexical diversity showed little developmental progression. Inter-individual variability in…

A review of the literature and research on the academic and social self-concepts of gifted adolescents reveals the importance of considering the unique talents of the individual rather than considering gifted students as a homogeneous group. Implications of the research for encouraging positive self-concepts in these students are drawn. (Author/DB)
