Discusses semantic communication networks, methods of content analysis, and voice mail as a communication system. A study that examined conceptual distinctions between voice mail answering and voice mail messaging in a large insurance organization is described, and semantic network analysis is compared to traditional content analysis. (28…

Describes two classroom experiments that investigated the effects of using projected-display computers: the first compared teaching a course using a projected display with teaching the course in a computer lab; and the second compared using a computer and projected display with standard lectures. Effects on test scores are discussed. (three…

Describes a study conducted at Iowa State University that investigated the effects of using guided programing instruction to train analogical reasoning. Two groups of students are compared who received different types of programing instruction, and the far transfer and the near transfer of instruction are explored. (35 references) (LRW)

A statistical test for detecting answer copying on multiple-choice tests based on Cohen's kappa is proposed. The test is free of any assumptions on the response processes of the examinees suspected of copying and having served as the source, except for the usual assumption that these processes are probabilistic. Because the asymptotic null and…

Comparing variability of test scores across alternate forms, test conditions, or subpopulations is a fundamental problem in psychometrics. A confidence interval for a ratio of standard deviations is proposed that performs as well as the classic method with normal distributions and performs dramatically better with nonnormal distributions. A simple…

Dutch and Belgian immigrants in California have a high rate of unresolved attachment status compared to nonimmigrant Californians, unrelated to their length of time in the United States, to their marriage status, or to their reasons for immigration. In this study, the author analyzes attachment at the representational level by comparing coherence…

Explicit timing and interspersal interventions were investigated using a within-subjects design with 45 third-grade students. A control assignment consisted of subtraction of a two digit number from a two digit number (i.e., target problem) and served as a baseline. An explicit timing assignment consisted of similar problems as those for the…

The aim of the research presented in this paper is to contribute to our knowledge about problem solving in mathematics. My purpose in this paper is to compare, from this point of view, two very different institutions in the French tertiary education system, with the intention to interpret the chronic inequality of performance in problem solving…

Recent studies have suggested that unusual visual processing in autism might stem from enhanced visual discrimination. Although there are also many anecdotal reports of auditory and tactile processing disturbances in autism these have received comparatively little attention. It is possible that the enhanced discrimination ability in vision in…

This paper reports the findings of an experiment that investigated the reactions of Saudi college students to collaborative learning techniques introduced in two modalities: face-to-face and web-based learning. Quantitative data were collected with a questionnaire that examined the changes of three constructs: attitudes toward collaboration,…

This book discusses the motivations that cause adults to go to the public library. It is grouped into eight sections concerning: (1) the research methodology and results used to determine four motivators that were good predictors of library use; (2) the development of library research; (3) several characteristics of library users in terms of…

This investigation of the effect of computer-assisted instruction (CAI) on the learning of library skills hypothesized that there would be a substantial difference in the achievement of library skills by those students who received additional drill and practice through the use of CAI and those who received additional drill and practice only from…

This study investigated the extent to which participation by high school students in a computer programming course leads to improved critical thinking skills, and whether a significant difference exists in critical thinking skill development between participants in Pascal and BASIC classes. Three groups of high school students were tested using…

PUBLISHED CHILDREN'S VOCABULARY LISTS BASED ON ACTUAL USAGE ARE ALL DRAWN FROM RESEARCH DONE PRIOR TO 1930. THE PRESENT STUDY REPLICATED THE 1926 BUCKINGHAM-DOLCH STUDY TO DETERMINE ANY VOCABULARY CHANGES. THE 2 HYPOTHESES TESTED WERE (1) THERE IS NO SIGNIFICANT VOCABULARY SHIFT, AND (2) COMMON WORDS DID NOT DIFFER IN GRADE-PLACEMENT (THE EARLIEST…

We concern ourselves with the hypothesis that two variables have a perfect disattenuated correlation, hence measure the same trait except for errors of measurement. This hypothesis is equivalent to saying, within the adopted model, that true scores of two psychological tests satisfy a linear relation. Statistical tests of this hypothesis are…
