The purpose of this study was to determine if correlations among student ratings items designed to be diagnostic could be lowered through use of special instructions to raters. The authors argue that the lowering of inter-item correlations is indicative of a reduction of the halo effect which leads to greater item diagnosticity. The experimental…

A three-year longitudinal study conducted to assess the incidence of mixed laterality in elementary school children showed that thirty-seven percent of the eighty-two subjects had mixed laterality. No relationship was found between perceptual motor and academic achievement as measured by teacher ratings and mixed laterality. (MF)

Critiques comparative research and evaluation methods used to assess effectiveness of interactive video and proposes alternative models of research design that go beyond comparative analysis into understanding and control of the effective dimensions of interactive video, i.e., controlled correlation; instructional events, cognitive psychology, and…

Analysis of the free speech of one- to three-year-olds (N=21) found that measures of mean length of utterance (MLU) are positively related to age, are reliable, and can predict grammatical development, although there are identifiable points in the developmental evolution of MLU and MLU-like indices beyond which their reliability and validity have…

Detailed analysis of frequencies of the primary auxiliary verb "be" in Scots dramatic texts leads to consideration of the typological relationship said to exist between different varieties of Scots and between them and standard English. (Author/CB)

Differences in procedures used by academic institutions and government agencies in administering the American Council on the Teaching of Foreign Languages' Oral Proficiency Interview test are examined, and results and implications of two studies of interrater reliability are discussed. (MSE)

Reviews study of 80 undergraduate sociology students which compared the effects of two types of sequencing in computer assisted instruction: (1) linear, or fixed, and (2) flip, or branching. Results indicate that students in the flip sequence condition performed better on comprehension measures but not on retention measures. (Author/LRW)

Intermediate-level English as a second language students were examined for levels of reading comprehension. Half of each group (experimental and control) received more complete versions of test passages than the other half, and the experimental group was taught appropriate cultural background information between tests. Background knowledge did…

Describes study conducted with U.S. Marine Corps enlisted personnel to measure response time to computer-administered questionnaire items, and to evaluate how measurement of response time might be useful in various research areas. Topics addressed include mood states; the occurrence of straight lining; and experimental effects of sleep loss and…

Compared the efficacy of two methods of cluster analysis, the unweighted pair-groups method using arithmetic averages (UPGMA) and Ward's method, for students grouped on intelligence, achievement, and social adjustment by both clustering methods. Found UPGMA more efficacious based on output, on cophenetic correlation coefficients generated by each…

Describes methods used to evaluate software for microcomputers in Japanese elementary and middle schools. Completion of an evaluation checklist by experienced teachers is described, the cluster analysis used is reviewed, and characteristics of available software are discussed and analyzed to assess their learning and teaching efficiency.…

Activities which focus on form and communicative outcome are suggested for developing accuracy and fluency in second language students. Examples of such activities (with focus on the English as a second language learner) that vary the circumstances of communication in the classroom are presented. (Author/CB)

Criterion-related validity of the 126-item cognitive test used in the High School and Beyond study was examined.
