Children appear to interpret the "equals" sign as an operator ("adds up to") not a relational ("the same as") symbol--e.g., viewing equations like 13 = 7 + 6 or 8 = 8 as senseless. This study, a natural experiment, examined the effects of long-term instruction emphasizing a relational definition of "equals."…

The purpose of this paper is to: (1) explore some possible explanations for the lack of empirical support of advance organizers; (2) suggest a plan for improving the empirical research on advance organizers; and (3) recommend some further investigations needed in the area of advance organizers. Some explanations for this lack of support are…

This exploratory study was aimed at uncovering children's beliefs and ideas about the human circulatory system. Thirty-two subjects, aged 7 to 14 years, were interviewed using a modification of Piaget's clinical method. The data were analyzed by developing a conceptual inventory of beliefs for each of five research questions. It was found that the…

Discourse comprehension involves readers or listeners in constructing mental models using local text information, global text structures, and their general knowledge of the world. An analysis of the literature on children's understanding of spoken discourse reveals that young children are capable of forming mental models from texts, but that their…

This paper reports on an investigation of children's ability to accept contrary-to-fact premises as though they were factual and to reason accordingly. A variety of questions requiring this skill were presented in semi-structured interview form to 10 to 12 subjects from each of six age groups ranging from 5 to 9 years, and to a control group of…

This paper presents a developmental study of the problem solving strategies of reflective and impulsive children. Subjects for the study were 30 nine-year-olds, 39 eleven-year-olds, and 23 thirteen-year-olds who had been classified as reflective or impulsive at ages 7, 9, and 11 and who had been followed longitudinally over a three year period.…

This exploratory study was conducted to interpret age and individual differences in 48 kindergarteners' and second graders' performance on a referential communication task in light of the Pascual-Leone Theory of Constructive Operations, a neo-Piagetian theory of cognitive development. Stimulus materials were black and white photographs of dogs,…

A distinction can be made between the term "creativity" and creative thinking skills. Creativity typically refers to a talent for original and masterful production in the arts and sciences, and there is scant evidence that teachers have any influence on creativity of this kind. Creative thinking refers to a group of six thinking skills that if…

In order to provide an estimate of encoding within the active mode and a comparison between three modes of representation (enactive, imagery, and verbal), 36 second grade children from the high socioeconomic community of Beverly Hills, California, were presented with object pairs under one of three conditions (haptic-object versus visual-object…

The T.V. Taxonomy of Questions was developed for use by teachers who wish to stimulate their students' critical thinking skills, but who find the terminology of existing skill taxonomies both confusing and elusive. This taxonomy consists of six levels of questions. Each level is given the name of a television program reflecting how the student…

This study was designed to examine effects that access to manipulatives in science instruction have with respect to the development of spatial conceptual abilities and whether the effects were different for males and females. A secondary purpose of this investigation was to examine what relationship sex and access to manipulatives in conjunction…

Conceptual level is a personal characteristic that describes persons on a developmental hierarchy of increasing conceptual complexity, self-responsibility, and independence. The relationship between gender and conceptual level was explored in a group of 70 male and 63 female college students. The This I Believe Test (TIB) was administered to…

Nine articles on the young adolescent consider the ability of middle schools to adapt to the needs of their students, the educational implications of preadolescent development, adolescent brain growth and cognitive ability, and the relevance of Piaget's psychology to the middle school. The authors' conclusions include the necessity to identify and…

Research is described concerning a factor analytic view of adolescent thought in Piagetian context. Included are a description of Piagetian tasks used for determining stage of mental development, studies concerning Piagetian task factor analysis, and the current factorial structure of adolescent thought.

This study investigated a theoretical structure which attempts to explain the problem-solving strategies used by first-grade students who are successful in solving simple arithmetic story problems. The structure used describes the problem-solving procedure as consisting of a three-stage model building process: (1) comprehending the story, (2)…
