Interpretive issues with the Roberts Apperception Test for Children: Limitations of the standardization group

This study investigated the validity of the Roberts Apperception Test for Children (RATC) with an elementary school sample by examining the appropriateness of the standardization norms with other nonclinical samples. A sample of 86 children, ages 8–11 years, completed the RATC. Analyses revealed that the current sample of nonclinical children differed significantly from the standardization sample on six of the eight Adaptive Scales and three of the five Clinical Scales. Findings suggest that the children in this study form a separate and distinct group from the well‐adjusted children upon which the RATC scales were normed and supports previous research that suggests the standardization of the RATC is inadequate. The current findings strongly suggest that the norms for the RATC not be used for clinical diagnosis until restandardization is completed. © 1999 John Wiley & Sons, Inc.     

Using kindergarten number sense to predict calculation fluency in second grade

Children's number sense in kindergarten was used to predict their calculation fluency in second grade (N = 198). Using block entry regression, usual predictors of age, reading, memory, and verbal and spatial cognition were entered in the first block and number sense measures were added in the second block. Number sense measures contributed a significant amount of variance over and above the more general predictors (26%-42%). Uniquely predictive subareas were active memory for numbers, number knowledge, and number combinations, with number combinations standing out as the strongest single predictor. Number sense screening in kindergarten, using "at-risk" versus "not-at-risk" criteria, successfully ruled out 84% of the children who did not go on to have calculation fluency difficulties and positively identified 52% of the children who later showed fluency difficulties. The relation of early number skills to later calculation fluency has important implications for math screening and intervention.     

Evolving Technologies Support Mobile and Collaborative Curriculum: A Case Study

This case study describes the efforts of librarians to integrate mobile devices, collaboration tools, and resources into a School of Medicine third-year pediatric clerkship. Additional class emphasis is on evidence-based searching and journal article evaluation and presentation. The class objectives ensure that students are comfortable with mobile devices and collaboration tools. Over the eight-year history of the course, student acceptance of the mobile devices used diminished as the devices aged, necessitating the evaluation and selection of new technologies. Collaboration tools and mobile applications employed in the course evolved to accommodate curriculum changes.     

Educational Programs for Elementary Students with Learning Disabilities: Can They Be Both Effective and Inclusive?

One of the most controversial issues in special education over the last 40 years has been the extent to which students with learning disabilities (LD) should be educated in general education classrooms. Recent mandates in federal law requiring that all students with disabilities have access to the general education curriculum and make adequate yearly progress relative to this content have intensified this debate. In this article, a brief summary of research regarding the nature of instruction that produces significantly improved educational outcomes for students with LD is provided. This is followed by a review of research related to the delivery of this high‐quality instruction in inclusive, general education classrooms and in resource settings. We conclude that this research provides the foundation for reconsidering full inclusion and how services are delivered for elementary students with LD.     

学习科学与教育政策——2011计算机支持的协作学习国际会议回顾

2011计算机支持的协作学习国际会议于2011年7月在香港举行。此次会议的主题是计算机支持协作学习的研究与教育政策和实践的链接,旨在促进CSCL研究对各级正规和非正规教育领域的政策和实践带来新启示。会议集中了全球学习科学、教育技术与协作学习领域的前沿科学家,是一次有关学习科学的盛会。除了在香港的研讨会,本次会议还增设了在广州、上海和北京的连锁会,因此在大陆也吸引了不少学者参与。作为2011CSCL会议的前奏,主办方在香港举行了一个小型的全球教育政策论坛,20位成员之中,一半是前沿的学习科学研究人员,另一半则是各国际机构的教育政策领军人物,他们就教育的微观与宏观研究,做了别开生面的对话。我们相信,有关学习科学的研究,必将成为教育领域的基础研究。     

Assessing early arithmetic abilities: Effects of verbal and nonverbal response types on the calculation performance of middle-and low-income children

In two studies, we compared young children's performance on three variations of a nonverbally presented calculation task. The experimental tasks used the same nonverbal mode of presentation but were varied according to response type: (1) putting out disks (nonverbal production); (2) choosing the correct number of disks from a multiple-choice array (nonverbal recognition); and (3) giving a number word (verbal production). The verbal production task required children to map numerosities onto the conventional number system while the nonverbal production and nonverbal recognition tasks did not. Study 1 showed that the performance of 3-, 4- and 5-year-old middle-income children (N = 72) did not vary with the type of response required. Children's answers to nonverbally presented addition and subtraction problems were available in both verbal and nonverbal forms. In contrast. Study 2 showed that low-income children (3- and 4-year-olds; N = 48) performed significantly better on both nonverbal response type tasks than on the verbal response type task. Analysis of individual data indicated that a number of the low-income children were successful on the completely nonverbal calculation tasks, even though they had difficulty with verbal counting (i.e., set enumeration and cardinality). The findings suggest that the ability to calculate does not depend on mastery of conventional symbols of arithmetic.     

Patterns of Social Interaction of Mainstreamed Preschool Children: Hopeful News from the Field

Much of the research on social interaction in mainstreamed settings has focused on “reverse mainstreamed” or special environments in contrast, the present study observed 600 social interactions in 19 regular preschools. Three findings emerged: a) retarded children are substantially integrated into the emotional and social life of the peer group, but not fully integrated into peer group verbal life; b) there is an inverse relationship between teachers’ initiation of social interaction with retarded children and the degree to which the latter are integrated into peer group life; and c) teachers provide retarded children with more verbal enrichment and emotional protection than these children receive from their peer group. On balance, these findings are fairly encouraging, suggesting that to a considerable extent mainstreaming is working in preschool classrooms.     

Auditory Frequency Resolution in Human Infancy

Frequency resolution is a fundamental capacity of the auditory system that underlies the perception of all complex sounds. The development of this capacity has not been well characterized in humans. This investigation used a nonsimultaneous pulsation threshold technique to examine the development of infant frequency resolution. Psychophysical tuning curves were obtained for 3- and 6-month-olds and for adults at either 500, 1,000, or 4,000 Hz. Both the sensation level and the sound pressure level of the stimulus were varied for adults to determine the contribution of stimulus intensity to age differences in frequency resolution. At 500 and 1,000 Hz, 3- and 6-month-olds' tuning curve widths were equivalent to adults'. At 4,000 Hz, the 3-month-olds' tuning curves were broader than those of 6-month-olds and adults, even when absolute sound pressure level was equivalent. The maturation of psychophysical frequency resolution in infants is discussed in terms of the general development of the auditory system and of nonsensory factors that might contribute to age differences in performance.     

A systematic follow‐up approach for mainstreaming students with behavior and emotional disorders

The Behavior Intervention Centres are part of the Houston Independent School District's (HISD) Special Education Department. Their purpose is to provide educational services to elementary and secondary students, aged 3 through 21, who exhibit either severely aggressive or severely withdrawn behaviours. This article describes a formalized follow‐up service considered by the authors to be a critical component of the BIC program.
