A frequent reason for teachers not making special provisions for a gifted child is that the child is "not fitting in socially." The conjecture that a psychological source of such negative affect has evolved along with human language was tested with a large sample (N = 377) of teachers in England, Scotland, and Australia who were…

This study tested the hypothesis whether older dyslexic children may obtain fewer gains on fluency and accuracy with respect to their younger peers after specific remediation. Changes in accuracy and fluency of a group of children with a diagnosis of dyslexia attending third and fourth grades were compared with those obtained by a group of…

This paper examines how differences in curricular design of undergraduate accounting programs influence pass rates on the Business Environment and Concepts Section of the CPA Exam. The association of the pass rate of a school's accounting graduates to the design of the schools accounting program and to other school characteristics was examined…

This exploratory study investigates the potential of Wiki technology as a tool for teaching and learning. Wikis are a component of Web 2.0 technology tools that provide collaborative features and active learning opportunities in a web-based environment. This research study sought to empirically determine the pedagogical value of using Wiki…

New multivariate permutation tests are proposed that may be effectively substituted for Hotelling's T-Square test in situations commonly arising in educational research. The new tests: (1) are distribution-free; (2) provide tests of directional as well as non-directional hypotheses; (3) may be tailored for sensitivity to specific treatment…

This paper begins by reviewing the results of research on the potential of adjunct questions for teaching both rote recall and intellectual skills, i.e., concept learning, problem solving, and rule learning. It is argued that greater understanding of what kinds of questions best support intellectual skills learning will promote effective…

A 2-to-the-kth-power mirror-image design is defined as one in which repeated observations of subjects occurs among the levels of a usual 2-to-the-kth-power design, but there is the restriction that no subject may receive a given level of any factor more than once. Such a restriction might arise, for example, if a subject's response is expected to…

This study tested Deiker's hypothesis that "naysaying" accounts for the Minnesota Multiphasic Personality Inventory Overcontrolled-Hostility (O-H) scale's ability to discriminate among criminal groups differing in their propensity for violence. It was concluded that the validity of the O-H scale is not dependent on naysaying. (Author)

Threedifferent statistical procedures for identifying aptitude-treatment interactions are discussed: (1) treatment x blocks analysis of variance (2) homogeneity of groups regressions and (3) extreme groups analysis. (Author)

Replication is important to viable scientific inquiry; results that will not replicate or generalize are of very limited value. Statistical significance enables the researcher to reject or not reject the null hypothesis according to the sample results obtained, but statistical significance does not indicate the probability that results will be…

This study of factors that block computer implementation in classrooms tested four hypotheses about the attitudes of preservice and inservice teachers toward scheduling arrangements and instructional use of computers in their classrooms. A semantic differential survey instrument was used to measure the attitudes of 36 Washington State University…

The background of 197 university students from four introductory computer science classes at the State University of New York at Buffalo was investigated to determine factors contributing to academic success or failure in computer science. A background questionnaire, a test of computer science concepts (reading a simple program, symbol…

Using a Monte Carlo approach, comparison was made between traditional procedures and a multiple linear regression approach to test for differences between values of r sub 1 and r sub 2 when sample data were dependent and independent. For independent sample data, results from a z-test were compared to results from using multiple linear regression.…

This study examines the relative effectiveness of two means of analyzing the pre-test/post-test control group experimental design. Samples were randomly drawn from a standardized normal population and assigned to one of the four cells of the design. A set of experimental differences were induced in the post-test experimental cell. Each case was…

Two experiments investigated relationships between state anxiety, memory processes, and children's performance on problem-solving tasks. Participants were second and sixth graders in a private elementary school in Redlands, California. In both experiments, subjects responded to three training and eight test problems presented in the introtact…
