The Developmental Sequence and Relations Between Gesture and Spoken Language in Toddlers With Autism Spectrum Disorder

In typical development, gestures precede and predict language development. This study examines the developmental sequence of expressive communication and relations between specific gestural and language milestones in toddlers with autism spectrum disorder (ASD), who demonstrate marked difficulty with gesture production and language. Communication skills across five stages (gestures, word approximations, first words, gesture-word combinations, and two-word combinations) were assessed monthly by blind raters for toddlers with ASD participating in an randomized control trial of parent-mediated treatment (N = 42, 12–30 months). Findings revealed that toddlers acquired skills following a reliable (vs. idiosyncratic) sequence and the majority of toddlers combined gestures with words before combining words in speech, but in contrast to the pattern observed in typical development, a significant subset acquired pointing after first words.     

The evaluation of faculty development programs

This article reviews literature pertinent to the evaluation of faculty development programs and presents data from several studies conducted at two institutions. These data were consistent with those previously reported in that faculty participants consistently expressed satisfaction with development services. In addition, one study found that most faculty members voluntarily took some action to improve their instructional effectiveness, though only a minority pursued these efforts in depth. Volunteers who worked intensively with a faculty development consultant improved more on objective measures of effectiveness than did those who were only superficially involved in improvement efforts; those who received no consultative assistance failed to improve significantly. Evidence from a final study provided a control for faculty motivation and led to the conclusion that improvement was contingent both on faculty desire to improve and on the availability of professional assistance.     

Personality structure,instructional outcomes,and instructional preferences

Four instructional treatments differing in structure and student responsibility were used with 60 abstractthinking and 60 concrete-thinking students. As predicted, abstract students preferred those treatments with less structure and more responsibility; however, abstract and concrete students showed similar achievement levels as a result, of each treatment. The differentiated outcomes hypothesis is offered to account for the findings.

Résumé Quatre méthodes de traitement pédagogique de structure et de responsabilité des étudiants ont été employées avec 60 étudiants pensant abstraitement et 60 étudiants pensant de manière concrète. Ainsi que prévu, les étudiants pensant abstraitement préféraient les méthodes ayant moins de structure et plus de responsabilité. Les deux catégories d'étudiants ont toutefois obtenu des niveaux d'accomplissement pareils avec chaque méthode de traitement. L'hypothèse des aboutissements différenciés est offerte comme explication des conclusions.

AN EXAMINATION OF THE CONTEXT EFFECT IN ITEM SAMPLING

Item sampling and/or multiple matrix sampling techniques have been recommended for a variety of purposes. For some of these purposes, it must be assumed that examinee performance on a set of items is unaffected by the conditions under which the items are taken (i.e., no context effect exists). In this paper factors that may lead to a context effect among high school students are discussed. The net effect of such factors on examinee scores for an English test and a mathematics test is investigated empirically. For the English test there was little support for the existence of a context effect, However, a definite context effect was found for the mathematics test.
