Suggests some difficulties and challenges in understanding and teaching Piaget's new theory. Outlines some differences between Piaget's new and standard theories, such as the diminished status of the emergent skills that mark the onset of concrete operational thinking and the perception of achievements in concrete operations as empirical…

Used multiple baseline design with four 6-year-old Latino children to train in class inclusion through counting, feedback, and verbal reinforcers, and in English language skills (of benefit in their own right), over 5 months. Found that post-intervention gains in the two domains were significant and were stable over at least 4.5 months. (KB)

The hypothesis that variation in accessibility of categorical knowledge affects its use as an organizational device was tested in this experiment using 36 second graders and 36 fifth graders from a middle-class community within San Diego, California. The students memorized each of two lists of words that differed in category representativeness.…

This study investigated the linguistic components of Piaget's class-inclusion task. First, hierarchical classification is examined from both Piagetian and linguistic theory points of view. Then, two general characteristics of child thinking that relate to the different interpretations of the responses to classification questions are discussed: (1)…

Two experiments which investigated the young child's ability to deal with multiplicative classes and relations (considered behavioral indices of concrete operations thought) in double series and cross class matrices are described and discussed. In the initial study, 160 children from preschool through grade 2 received six matrix subtasks…

To examine how young children learn to read new words, we asked preschoolers (N = 115, mean age 4 years, 8 months) to learn and remember novel spellings that made sense based on letter names (e.g. TZ for "tease") and spellings that were visually distinctive but phonetically inappropriate. Children who were more knowledgeable about letter names…

If, as research suggests, exposing children to two languages and two cultures provides a cognitive advantage, it could be assumed that a child exposed to two languages may be accelerated in a more advanced cognitive stage (as defined by Piaget) than a child exposed to only one language. This study sought to determine when Hispanic children from…

The second of three volumes, this document provides a description of the coding system, the rules and the procedures followed in interpreting and classifying 4,896 statements of desired program effects on Head Start children. The statements had been identified and rated by parents, staff and teachers in Input Workshops conducted by the Head Start…

Piaget's model of children's conceptual learning and development was compared with Klausmeier's Conceptual Learning and Development (CLD) model in a longitudinal study. The CLD model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known…

The third of three volumes, this document provides (1) a reduced list of child development characteristics obtained from parents, teachers, and staff participating in Head Start Input Workshops set up to identify desirable program effects; (2) a Tabulation of Importance Ratings, showing how workshop participants valued specific statements of child…
