Reclaiming Kindergarten: Part II: Questions About Policy

Part II of “Reclaiming Kindergarten” continues the discussion related to responding to the crisis in today’s kindergarten. In Part II, two policy questions are posed, the answers to which seek to respond to this continuing crisis. The questions center on issues related to engaging families in kindergarten and the need to consider a new early childhood paradigm where kindergarten is part of a continuous and seamless educational experience spanning prekindergarten through third grade. As in Part I, examples of classroom practice are used to illustrate the effective implementation of these principles in a kindergarten classroom.     

Facing multiculturalism’s challenges in Korean education and society

Multicultural policy in South Korea faces variants of challenges endemic to multiculturalism. These challenges are “dilemmas of difference,” “variable terms of inclusion,” and “legitimacy.” In Korea, these challenges arise in a setting in which ethnic diversity is of relatively recent origin, an ideology of ethnic homogeneity is prevalent, and official multicultural policy is limited in its reach to those who are designated as “multicultural families,” that is families in which one spouse is Korean and the other an immigrant, usually the wife, and their offspring. The exclusion of migrant workers and their families from Korea’s multicultural framework poses a core contradiction in Korean multicultural policies. This contradiction must be resolved if multiculturalism in education and other spheres is to promote equality and provide a foundation for national integration on terms that are equitable to the diverse constituents of Korean society. Inevitably, this will require a redefinition of what it means to “be Korean.” Even if multicultural policies fall short in their immediate effects on those toward whom they are directed, multiculturalism represents a significant shift in the discourse of Korean identity and will be terrain on which the status of diverse groups in Korea will be contested.     

Classroom behavior of children and adolescents with learning disabilities: a meta-analysis

Meta-analysis was used to review the results of 25 studies that compared the classroom behavior of children and adolescents with learning disabilities (LD) to children without learning disabilities. The data were analyzed from several different methodological perspectives. Results showed that both methodologically strong and weak studies demonstrated significant behavioral deficits of children with learning disabilities compared to their nondisabled peers in each of five overall areas: on-task behavior, off-task behavior, conduct disorders, distractibility, and shy/withdrawn behavior. Both observational and teacher rating data demonstrated these differences. Effect sizes for both groups of studies seemed to cluster around 1 standard deviation, suggesting noticeable and educationally significant impairment in the behavior of children with disabilities. Analysis of grade-level effect sizes suggests some explanation for the large number of referrals often witnessed during the elementary school years. Educational implications of these behavioral differences in terms of implications for mainstreaming are discussed.     

The expert witness in child abuse and neglect: An interdisciplinary process

The legal system is an important part of a society's response to child abuse and child neglect. Courts need to be guided in their deliberations by experts from many different professions. Consultation and in-court expert testimony is necessary from medicine, psychology, psychiatry, social work and other professions both to prove child abuse and neglect and establish the power of the court to act on behalf of a child but also to guide the court in the intervention strategy most suited to the needs of the child and his family. Non-lawyers often feel uncomfortable in the legal setting. The adversary process is foreign to their training and professional experience. Collaboration with a lawyer greatly improves their effectiveness in court. Lawyers, on the other hand, need to make maximum use of medical and social-psychological experts in the court process in the interests of their clients; but to do so lawyers need a basic understanding of the other professions. With an emphasis on a process of mutual education, the paper presents a framework for collaboration between lawyers and expert witnesses in child abuse and neglect cases. “Expert witness” is defined; informal consultation is encouraged; suggestions for selecting a collaborator are made; initial contracts between lawyer and expert, case conferencing and preparation for trial are discussed; specific advice on direct and cross examination is provided.     

Preschoolers perceptions of the unfairness of maternal disciplinary practices

OBJECTIVE: The aim of this study was to examine preschoolers' perceptions of maternal discipline's unfairness. The participants' gender, age, SES, family intactness and sibship size were examined for their possible relevance to such perceptions. METHOD: Five vignettes, describing forms of discipline the literature suggests constitute psychological maltreatment, were presented to 57 preschoolers (27 boys and 30 girls). They included excessive withdrawal of privileges, withdrawal of entertainment, differential treatment of siblings, threatening power assertion, and public humiliation. The children had to decide on the fairness or unfairness of each vignette in which a child was disciplined in each of these ways by his/her mother. They were then asked to offer an explanation for each of their choices. RESULTS: Of the five forms of discipline employed in the vignettes, children judged differential treatment of siblings as more unfair than either power assertion (threatening spanking), or public humiliation. No differences were found for withdrawal of privileges or entertainment. Of the various predictor variables employed, preschoolers from smaller families were more likely to judge threatening to spank as unfair. As well, compared to boys, girls and children from larger families were more likely to judge differential treatment as unfair. Age, SES, and family intactness had no effect on discipline judgements likely because of their limited range. CONCLUSIONS: The findings suggest that preschoolers can offer views on the fairness or unfairness of parental disciplinary practices, and can differentiate among them. Further, not all forms of parental discipline were viewed by preschoolers as unfair. Yet it has to be appreciated that the vignettes employed here were adapted for younger children, hence they may not have appeared as negative as in studies involving older children and adults.     

Preservice teachers’ use of contrasting cases in mathematics instruction

Drawing comparisons between students’ alternative solution strategies to a single mathematics problem is a powerful yet challenging instructional practice. We examined 80 preservice teachers’ when asked to design a short lesson when given a problem and two student solutions—one correct and one incorrect. These micro-teaching events were videotaped and coded, revealing that fewer than half of participants (43%) made any explicit comparison or contrasts between the two solution strategies. Those who did were still not likely to use additional support strategies to draw students’ attention to key elements of the comparison. Further, correlations suggest that participants’ mathematical content knowledge may be related to whether participants’ showed contrasting cases but not to whether they used specific pedagogical cues to support those comparisons. While these micro-teaching events differ from the interactive constraints of a classroom, they reveal that participants did not immediately orient toward differing student solutions as a discussion opportunity, and that future instruction on contrasting cases must highlight the utility of this practice.     

A review of social interventions for students with learning disabilities

Twenty-two studies are reviewed that report the effects of social skills training and intervention with 572 children identified as learning disabled between 5 and 19 years of age. These studies are reviewed to examine characteristics and components of intervention effectiveness. Age and sex of subjects, grade grouping, group size, intervention duration, intervention procedures, subject selection, and type of interventional model are examined to find patterns that reflect intervention success. Several intervention characteristics and components are associated with social intervention effectiveness: selecting subjects who had social skills difficulties or low peer acceptance, using cognitive-behavioral intervention procedures, providing individual or small group instruction, and applying long-term intervention and training. Discussion focuses on difficulties in comparing studies to determine intervention effectiveness through the examination of outcome measures, a call for revisions in future reporting of social interventions in the literature, and those intervention factors that relate to increases in peer acceptance.
