“She My Friend”: Implications of Friend Ideologies,Identities, and Relationships for Bilingual Kindergarteners

This study identifies how the contextual features of an elementary school setting shaped and often restricted bilingual kindergarten students' access to friendships within their grade-level English-dominant classroom. Data demonstrate how students utilized a teacher-designed lunch card routine to initiate, maintain, and display friendships in addition to indicating their lunch selection. Findings from the study prompted changes in my instructional practices as well as in the ESL and bilingual program design at the school in order to allow greater interaction between native English and native Spanish speakers. Implications of these findings include the significance of social relationships for language learning, for gaining status, and for motivating bilingual students to remain in school over the course of their K-12 education.     

Desalination of masonry structures: Fine tuning of pore size distribution of poultices to substrate properties

Desalination is a relatively new intervention in the field of conservation of architectural heritage. Especially the desalination of immovable objects, such as masonry structures, is still a trial-error practice. In the field, different desalination materials and methods are used, sometimes with unsatisfactory results. Better understanding of the desalination process is needed in order to support the conservator with clear guidelines for choosing a suitable desalination material and method. The research presented in this paper constitutes the first step towards the development of a modular system of poultices, which can be adapted, i.e. fine-tuned to different types of substrates. Starting point is to make use of advection, i.e. the transport of salt ions with water flow. This transport mechanism is faster than diffusion and the application on immovable objects is relatively easy. In order to optimize salt extraction, a poultice working by advection should have smaller pores than the substrate. Starting from this principle the pore sizes of different desalination materials (sand, cellulose, kaolin and bentonite) mixed in different proportions, have been measured. Interesting results were obtained, showing that the desalination materials commonly used in the field are often not the most suitable ones. On the basis of the results, recipes for poultices, adapted to a specific substrate, can be formulated.     

An investigation of the Iowa tests of basic skills for sex bias: A developmental look

Results of the Vocabulary, Reading Comprehension, and Mathematics Concepts subtests for third-, sixth-, and eighth-grade students who took Form 5 of the Iowa Tests of Basic Skills in the 1976 school year were analyzed for sex bias. Statistical significance was found for each subtest for all of the grade levels. Follow-up analyses considered skill classification, sex-stereotypicalness, and item location of the items contributing to the statistical significance. No trends for these factors were found within each grade level for the four subtests considered. For all subtests, fewer items are identified at the third-grade level than for sixth or eighth grade, and these items, in general, favored boys. For the older students, when items are found to function differently for boys and girls, nearly half favor each sex. On the whole, little evidence for sex bias was found for the four subtests and three grade levels examined.     

Gifted children and visual-motor development: A comparison of Bender-Gestalt and VMI test performance

A sample of 63 gifted elementary-school students was administered the Bender Visual-Motor Gestalt Test and the Developmental Test of Visual-Motor Integration for comparative purposes and to test Koppitz hypothesis that gifted students have advanced visual-motor development. Group results revealed no significant differences between the two tests, that they did correlate significantly, and that younger students in particular had advanced visual-motor development when tested using these two tools.     

What reasons are given by teachers who refer problem behavior students?

Referral information regarding 215 students referred to school psychologists was reviewed. Of this group, 74% were males and approximately one-half were referred while enrolled in the third through sixth grades. The most frequently stated reasons for referral were: (a) poor peer relationships, (b) displays frustration, (c) below academic expectations, (d) shy and withdrawn behavior, (e) disruptive behavior, (f) fighting, (g) refuses to work, and (h) short attention span. Referral reasons presented by classroom teachers correspond to the four major characteristics of behavior disorders: conduct disorders, personality disorders, inadequacy/immaturity, and socialized delinquency. Most referrals corresponded to reported behaviors representing conduct and personality disorders.
