This paper directs attention to the use of the EQUATIONS game as a research tool to study certain kinds of mathematical behavior, for example, the kinds of mathematical problems which players prefer to consider and to force their opponents to consider. Mathematical equations that meet certain game rule constraints constitute a problem space. A…

To investigate the affective and cognitive gains produced in an auto-tutorial world civilizations course, two groups of students were compared. A traditionally-taught (TT) section of 145 students and an auto-tutorially (AT) taught section of 140 were given pre- and posttests and used the same text and Modular Learning Program. The TT section…

This paper describes three interrelated studies which investigated the cognitions, feelings, and motives involved in the emergence and progression of prosocial behaviors. The first study examined the child's emerging sensitivities to the affective events in his environment through data collected over a 9-month period from groups of 10-, 15-, and…

The purpose of this study was twofold: first, to answer the question of which abilities, from a selected set of 12 abilities from the structure-of-intellect model of Guilford, were related to achievement in Physical Science Study Committee (PSSC) physics, and, second, to determine how the physics achievement prediction properties of these…

The purpose of this study was to determine whether children as young as second-graders could encode categorically within an abstract evaluative dimension. The study uses mode of stimulus presentation (auditory or visual) as an independent variable. The subjects were 40 white middle class children from grades 2, 4, and 6, who were randomly assigned…

The community college has become the institution of higher education which implements the American "open class" ideology, providing an opportunity for students to learn and advance themselves socially and occupationally. Evaluative research concerning compensatory education programs in the community college indicates that such programs have not…

This paper reviews nine studies which report conflicting results in assessing the relationship between children's role-taking ability and communication skills. The studies included satisfy three criteria: (1) role-taking and communication efficiency are measured independently; (2) tasks used to measure the two skills are significantly different in…

This study examines the degree to which young children are influenced by the familiarity of an adult participant in their pretend play with toys which vary in resemblance to highly prototypical objects (e.g., cup-like cups or doll-like dolls). A group of 29 children, mean age 21 months, was divided into two experimental groups balanced by sex; 15…

The role of language in conservation tasks and the development of the concept of conservation of quantity in young children are investigated in this study. A total of 50 children, aged 3.0 to 4.7 years, were divided into three groups according to age with a large number clustered around age 4.0 years. Children were randomly assigned to one of two…

The purpose of this study was to design a prototype written test of cognitive development based on the model of Piaget. Although the results were not consistent with Piaget's theory, test development was only partially successful. Specifically, validation of the scales was excellent or poor depending on the perspective. Analysis of the item…

The guide was developed as part of Project Prepare, a demonstration program designed to teach disadvantaged parents adult basic education skills and to show these parents how and what to teach their preschool children. It contains activities, advice, and resources for parents. All materials pertain to creative play for preschoolers that develop…

This booklet provides an annotated list of 48 research reports related to mathematics teaching and learning of primary school children, and a bibliographic listing of 102 additional papers dealing with these topics. Each bibliography is organized into five major divisions: (1) growth and development of children, (2) development of mathematical…

In this study concerning individualized instruction, forth fifth graders who had been taught language arts by an individualized instructional system since first grade were the experimental group. The control groups were of the same socioeconomic status and racial composition but had been taught by traditional methods of instruction. To assess…

Seven historical purposes have been proclaimed in American education since the turn of the century. The four familiar purposes are the American "quadrivium."
