Results are discussed with reference to a theoretical model of development-related control activities. (RH)

Methodological implications of a person-oriented, holistic-interactionistic perspective in research on individual development are outlined, desirable properties of a mathematical model of a phenomenon are discussed, and selected methods for carrying out person-oriented research are briefly overviewed. These methods are: (1) the classificatory…

Comparison of growth rates and menarcheal age for groups of boys and girls, ages 6 to 15, in Tokyo (Japan) found that children with mental retardation had a smaller growth spurt during puberty but did not differ in maturational rate defined by age at pubertal height spurt or age at menarche.

This paper presents a conceptual model for guiding research on homework. Based on elements derived from a review of 26 recent U.S. and international empirical studies of homework, the model emphasizes the need to consider many variables in order to reach an understanding of the design and conduct of homework assignments, homework completion, and…
