Relationship of WPPSI and subsequent metropolitan achievement test scores in head-start children

The MAT was administered to 35 original Head-Start children 3–4 years after initial WPPSI testing. WPPSI verbal IQ did not correlate significantly with any of the subject areas of the MAT, while Performance IQ correlated only moderately with mathematical components of the MAT (r = .42 – .52).

Is syllable segmentation developmentally constrained by consonant sonority within syllable boundaries in silent reading? Evidence in French children

There is agreement that French typically reading children use syllable‐sized units to segment words. Although the statistical properties of the initial syllables or the clusters within syllable boundaries seem to be crucial for syllable segmentation, little is known about the role of consonant sonority in silent reading. In two experiments that used audio‐visual and visual pseudoword recognition tasks with 300 French typically developing children, we showed a progressive increase in the use of syllable segmentation from the first through fifth years of reading instruction. The children were influenced both by an optimal ‘sonorant coda–obstruent onset’ sonority profile and by the individual position‐dependent consonant sonority within syllable boundaries. Orthographic and phonological statistical properties did not clearly modulate the response patterns. We provide innovative data to help further understand the developmental course of the use of syllable segmentation as determined by sonority. We discuss our results in the light of linguistic principles.     

Effect of physiological harvest stages on the composition of bioactive compounds in Cavendish bananas

The combined influence of maturation, ripening, and climate on the profile of bioactive compounds was studied in banana (Musa acuminata, AAA, Cavendish, cv. Grande Naine). Their bioactive compounds were determined by the Folin-Ciocalteu assay and high-performance thin layer chromatographic (HPTLC) method. The polyphenol content of bananas harvested after 400 degree days remained unchanged during ripening, while bananas harvested after 600 and 900 degree days exhibited a significant polyphenol increase. Although dopamine was the polyphenol with the highest concentration in banana peels during the green developmental stage and ripening, its kinetics differed from the total polyphenol profile. Our results showed that this matrix of choice (maturation, ripening, and climate) may allow selection of the banana (M. acuminata, AAA, Cavendish, cv. Grande Naine) status that will produce optimal concentrations of identified compounds with human health relevance.     

Watch Out for Relatives

In pedagogical literature, asynchronous, computer-mediated courses have been promoted as an interactive mode of course delivery. However, few studies have evaluated the effectiveness of different teaching strategies in this medium. In this paper, I describe the development of my asynchronous course and outline the fundamental dilemmas in attempting to achieve interactivity in this medium of course delivery. I discuss issues of pacing the course, grading, monitoring discussions, and incorporating Internet-based material into the course. Each of these considerations should be addressed in future research on asynchronous courses.     

Jogging the Jargon

Abstract

The results of a two-year study indicate that collaborative testing is a valuable pedagogical strategy that can both assess and enhance student learning. After finishing their first attempt at each exam, students were given a second attempt either working collaboratively in small groups or individually with open books and notes. Collaborative testing consistently produced significantly higher test scores. In addition, students' retention of course content is shown to be improved when collaborative testing is used. Concerns about grade inflation are alleviated through the use of proportionally weighted grading.

Uses of computer‐mediated political communication in the 1992 presidential campaign: A content analysis of the Bush,Clinton and Perot computer lists

This article presents a content analysis of three computer‐mediated communication (CMC) networks used for political discussion during the 1992 Presidential election campaign. Data indicate that the main use of computer networks in the campaign was to assert personal opinions about the candidates, issues, and the election. Other uses were talking about one's own life and experiences, telling others what they should be doing, and posting information for others to read. Significant differences were found between the three campaigns for uses of these computer networks. The Clinton network was used more than the other two for posting information. The Perot network was used more than the others for asserting opinions. This study indicates that voters have specific functions for the use of computer networks as new channels of political communication. Future research should examine what groups of voters use these networks the most and how such use affects candidate image formation. Suggestions are offered for the study of campaign computer lists in the upcoming presidential election of 1996.
