Developmental differences in categorization in a communication situation were investigated among 16 adult women and 16 nine-year-old children who instructed 7-year-old children in either the organization of groceries in a mock kitchen (home task) or the sorting of photographs of common objects into compartments (school task). In both tasks, the 18…

Repeated but unadvised attempts have been made by music educators to relate the Piagetian concept of concrete operational thought to children's understanding of music. The attempts have been focused on the apparent link between the child's detection of invariance in musical patterns and the concept of conservation. These attempts are unadvised…

Many articles have appeared in the educational, instructional, and psychological literature questioning the adequacy of the technology available for devising instruction, and the usability of the instructional research literature as a source of the technology. A systematic planning model is a useful framework for organizing what has to be done to…

The act of composing is best described as a set of distinguishable processes that interact. There are four methods for researching these processes: (1) behavior protocols, in which subjects are observed but are not asked to report their thought processes verbally; (2) directed reports, in which subjects are asked to explain how they performed a…

The net result of the social-scientific developments in the 19th and 20th centuries is that educational research has inherited a science that is assumed to constitute a disinterested technology of social engineering and a benevolent source of positive social advance. Unfortunately, the social experiment conducted on traditional lines depends upon…

This study investigates the vocabulary development of preschool children in the five programs of the Mt. Druitt Early Childhood Project, New South Wales, Australia. A Vocabulary Assessment Task was designed to tap the customary style of reference used by preschool children in response to familiar objects, and to test the qualitative levels of the…

Noting that in Europe there is a growing criticism of the largely American communication research tradition that focuses on individuals, this paper examines European-style "critical analysis," which looks at social systems. The paper first examines the criticism of American-style "administrative" research, and then discusses…

The problems with using Piagetian theory to explore language-thought relationships are two-fold. First there are methodological problems, including the lack of experimental controls and the lack of uniform criteria by which cognitive operations are identified. A second difficulty is the questionable practice of interpreting child language…

The paper reviews the state of the art in evaluation research of direct instruction projects with handicapped students. The first section delineates research designs used (including norm referenced comparisons, nonequivalent comparison groups, and quasi experimental designs); major findings; and problems with each. A distinction is made between…

Research into teacher evaluation techniques has not provided conclusive answers due to a number of research problems, including the subjectivity of traditional teacher observation techniques and the lack of sensitivity of newer, more objective techniques. A five-year research project in California, the Beginning Teacher Evaluation Study (BTES),…

This brief paper presents a sequential walk through a simple research setting--a two group experiment--to indicate common but avoidable design difficulties that may jeopardize the usefulness of the data obtained. The six flaws examined are the failure to select subjects from the population to which generalizations are to be made; failure to use…

Children's ability to understand the implied messages in indirect speech was investigated using a role play elicitation task. Subjects were asked to complete story endings using puppets for several scenerios involving a mother and her four children. In each of the stories the mother gives an indirect directive which is supposed to get the children…

The uses and restrictions of commonality analysis are described. Commonality analysis has been increasingly used as a method to examine the relative importance of independent variables, through the partitioning of variance among the variables of the regression equation into unique and common components. The effects of all other independent…

This report analyses justifications gathered in a series of studies which led intellectually normal infants' school and nursery school children and mildly mentally retarded special day school children to acquire conservation understanding. Two hundred and five children were given a pretest of number, mass, length, liquid, and weight conservation.…

Problems for the biographical researcher in conducting oral interviews with primary sources are discussed. Successful biographical research using oral history must be thorough and honest. A major problem in getting candid information from primary subjects may occur if quotations touch upon areas considered personal or controversial. Other problems…
