The effect of modern standard arabic orthography on speech production by Arab children with hearing loss

This article examined the effect of Modern Standard Arabic orthography on speech production quality (syllable stress and vowels) by 23 Arabic-speaking children with severe or profound hearing loss aged 8-12 years. Children produced 15 one-syllable minimal pairs of words that differed in vowel length (short vs. long) and 20 two-syllable minimal pairs differing in stress pattern. Each word was produced in three tasks: reading partially or fully vowelized words and imitation of aural stimuli. Results showed that fully vowelized words ensured vowel production: high-quality productions appeared on 99%, 74%, and 59% of productions on reading fully vowelized words, partially vowelized words, and on imitation, respectively. Moreover, correct vowel production affected correct consonant production. Correct production of stress was best on reading fully vowelized words, appearing on 54%, 21%, and 33% of productions for fully vowelized words, partially vowelized words, or imitation, respectively. Findings suggest the need to present fully vowelized written texts when teaching speech production to children with hearing loss. Such presentations enable more accurate productions that result in more intelligible speech.     

The ivory tower revisited

The corollary of the concept of the ‘ivory tower’, as reflected in the writings of Plato and Newman amongst others, was, paradoxically, the vital importance of the university for wider society. Nevertheless from the mid-twentieth century, the esteem in which a ‘liberal’ university education was held was diminished by rising expectations that higher education institutions would actively contribute to addressing broader socio-economic challenges through ‘knowledge-transfer’, education for employment, and community service. However while this linear conception of universities' ‘third mission’ eroded their ‘ivory tower’ status, the death knell of the ‘ivory tower’ rings in contemporary literature on higher education, which articulates a dialectical view of its historical development in which the university and wider society are synthesised in the ‘engaged university’. With its focus on reciprocal ‘knowledge-exchange’, the co-creation of knowledge through teaching and learning, and civic engagement, the ‘engaged university’ embraces the ‘other’ as intrinsic to its identity. Yet arguably the increasing instrumentalism and democratisation of higher education are irrevocably eroding the academic freedom and institutional autonomy upon which universities' immeasurable contribution to society ultimately depends.     

The Interaction between Gender, Age, and Multimedia Interface Design

In this study we assumed that multimedia design contributes to an interest in learning by young children. Thirty kindergarten children were exposed to interactive multimedia stories. With the help of the Pollimeter tool (Lampert, 1981), we examined previous experience with computers, level of covert time-on-task, and level of satisfaction with various interfaces. The findings indicate that different interfaces have a different impact on boys and girls as regards covert time-on-task and level of satisfaction with the interface. Boys who are more familiar with computer games show a greater covert time-on-task than girls, as also a higher level of satisfaction. Younger boys and girls were found to show higher satisfaction than older children.     

A potential for learning probability in young children

Sixty-one children, from 4 to 11 years old, were presented with two sets, each containing blue and yellow elements. Each time, one colour was pointed out as the payoff colour (POC). The child had to choose the set from which he or she would draw at random a POC element in order to be rewarded. The sets were of varying sizes with different proportions of the two colours. The problem was to select the higher of the two probabilities. Three kinds of materials were used: Pairs of urns with blue and yellow beads, pairs of roulettes divided into blue and yellow sectors, and pairs of spinning tops, likewise divided into two colours.Roughly around the age of six, children started to select the greater of the two probabilities systematically. The dominant error was selecting the set with the greater number of POC elements. Verbal concepts of probability and chance were explored and some egocentric thought processes were described. The study indicates that probability concepts could be introduced into school teaching even in the first grades. The deterministic orientation in the instruction for young ages should be attenuated, permitting concepts of uncertainty right from the beginning.     

Learning via mnemonic pictures: Analysis of the presidential process

In three experiments, junior high school students learned the numerical order of 14 U.S. presidents according to either a complex mnemonic strategy or their own techniques. Reliable performancepattern differences between the two groups were detected, both in the presence and absence of overall level-of-recall differences. Chief among the pattern differences were the classic serial-position profiles produced by control subjects, but not by those using mnemonic strategies, and the slower response times (suggesting a more complex retrieval process) of subjects using mnemonic strategies.     

Measuring the economic impact of institutions of higher education

Frequently institutions of higher education commission formal studies to measure their short-term economic impact on the surrounding regions. The purpose of this paper is to identify and discuss several of the methodological considerations which arise in the design and use of economic impact studies, as well as to present new evidence regarding the effectiveness of alternative survey methods for collecting the personal expenditure data frequently used in such studies. The survey results suggest that mail surveys may yield more accurate responses regarding important personal financial information than more costly telephone interviews. This paper also offers some guidance in the design of economic impact studies and points out some of the increasing pressures to integrate studies of short-term economic impacts with analysis of higher education's impact on long-term regional economic development.An earlier version of this paper was presented at the meetings of the Western Economic Association, Vancouver, British Columbia, Canada, July 1987.     

Misconceptions about Motion: Development and Training Effects

2 experiments were performed to examine whether children and adults possess a single-object/single-motion intuition. This intuition involves the view that because all parts of a rigid object move together, they all must move at the same speed. We found that third graders, sixth graders, ninth graders, and adults all responded in accord with this intuition. On problems where the intuition led to errors, a large majority of subjects of all ages answered incorrectly. On problems where it led to successful performance, subjects answered more accurately than on problems where the intuition was not applicable. In addition, the specific errors were those that the intuition yielded, and the intuition fit individual patterns of performance. The intuition not only influenced speed judgments but also judgments of distance traveled. Experiment 2 demonstrated that making sixth graders aware of the intuition and providing them kinesthetic experience that contradicted it produced significant improvements in the children's understanding. Implications for how scientific misconceptions in general can be overcome were discussed.
