Misconceptions in Van den Broeck's representation of misconceptions about learning disability research

The methods and conclusions of Van den Broeck (in this issue) are evaluated from two perspectives: (a) statistical considerations and (b) theoretical models of IQ and achievement, specifically reading achievement. We consider the statistical model proposed by Van den Broeck for the regression-based discrepancy model (RDM) to be either irrelevant or conceptually inconsistent with current models of IQ and achievement. The resulting simulation produced exemplar cases that are not realistic in terms of practice. The theoretical representations of IQ and achievement were, in our understanding, inconsistent with contemporary models of either. We suggest that acceptable models support the use of the RDM as it has been proposed by us and by others as one component of the determination of the presence or absence of a learning disability.     

Patterns in how pre-service elementary teachers formulate evidence-based claims about student cognition

Large-scale, robust implementation of teacher data-driven decision making (DDDM) is a challenging endeavor, impeded by numerous organizational, and teacher, factors. One well-documented barrier to teacher DDDM is underdevelopment of teacher data literacy. This study examines common errors made by pre-service elementary teachers in the formulation of evidence-based claims about student cognition (e.g. student strengths and weaknesses relative to content mastery) in a United States of America context. Teachers in the sample commonly made several errors in the articulation of evidence-based claims based on classroom assessments, including providing nonspecific, irrelevant evidence for claims, and misinterpreting statistical evidence. Specific implications for pre-service teacher education and future research are discussed.     

Defiant Behavior in Two- and Three-Year-Olds: A Vygotskian Approach

Defiant behavior in two- and three-year-olds is a natural expression of a young child’s growing autonomy, and, although frustrating to adults, is a natural phase of a child’s socio-emotional growth. L.S. Vygotsky’s socio-historical theory of the development included a discussion of “crisis” periods, one of which he felt occurred at age three. The crisis that Vygotsky asserted occurred at three is characterized by a group of seven “behaviors”, all of which indicate a struggle with the child’s position in relation to family social structures. This study examined the occurrences and characteristics of defiant behavior in two-and three-year-old children during outdoor play at a child development center, and the existence and context of defiant behaviors the modern childcare setting. Patterns in defiant behaviors during play in different age groups were apparent, and suggested an instrument to facilitate the documentation and analysis of defiant behavior in modern group-care settings.     

Teacher Evaluation and Teacher Effectiveness in the United Kingdom

An outline is given of the UK research situation for the knowledge bases of school effectiveness and teacher effectiveness, and the UK policy situation in terms of school and teacher evaluation, improvement and development. It is argued that the UK has seen a much greater use of school-level policies, reflecting its substantial school effectiveness research base, rather than teacher-level interventions, although there are currently some attempts at policy and practice level to focus upon teacher effects, teacher evaluation and related issues of professional development. Speculations are given concerning future policy and research needs.     

Assessing executive functions: A life‐span perspective

Despite many disagreements on the utility of neuropsychological applications in schools, executive function measures have been found to be useful across a variety of areas and ages. In addition, many disagreements are extant in discussions of the maturational course of the development of executive functioning abilities that are dependent on functional capacity of the human brain, including the frontal lobes, among other brain areas. In part, these controversies are related to a dearth of standardized functional assessments of executive functioning abilities across wide age spans. This article describes several recent measures of executive functioning and uses life‐span data from these assessments to project maturational periods of specific executive functions. Clinical implications of these results for school psychology assessment, rehabilitation of brain‐injured school‐aged children, and forensic practice of school psychology are posited. © 2008 Wiley Periodicals, Inc.     

Statistical edutainment that lines up and fits

Jokes, cartoons, songs, poems, and games can be useful ways to engage students in discussion and learning key concepts about regression.     

‘You can't see what the words say’: word spacing and letter spacing in children's reading books

This paper describes two tests designed to find out whether children would be helped in their reading by the use of word and letter spacing that was looser or tighter than commonly used default values. In each test, 24 six‐year‐old children were asked to read aloud in a classroom; the realistic, high‐quality test material was set using a range of either word spacing or letter spacing values. Audiotapes of the children's reading were analysed to determine reading rates; miscue analysis was used to compare the number and kind of errors they made on the different settings. The children were also asked for their views about the texts they read. The results suggest that children in the test groups did not benefit significantly from spacing that was substantially looser or tighter than our default values, and that they noticed differences in letter spacing more easily than differences in word spacing.     

‘I don't have time to be this busy.’ Exploring the concerns of secondary school teachers towards inclusive education

The trend towards inclusion in mainstream Australian schools has seen the numbers of students with disabilities educated in regular schools grow significantly. This trend has been supported by legislation such as the Disability Discrimination Act and the Education Standards. For inclusion to be successful, a number of factors are vital and teacher support for the programme is crucial. While there is research in the area of teachers’ concerns at the primary school level, little research has been conducted at the secondary school level. Research in this area is needed as the secondary school has differing factors from the primary sector that need to be explored.     

School-based early intervention and later child maltreatment in the Chicago Longitudinal Study

Investigated were the effects of participation in the Title I Child-Parent Centers (CPC) on substantiated reports of child maltreatment for 1,408 children (93% of whom are African American) in the Chicago Longitudinal Study. The CPCs provide child education and family support services in high-poverty areas. After adjusting for preprogram maltreatment and background factors, 913 preschool participants had significantly lower rates of court petitions of maltreatment by age 17 than 495 children of the same age who participated in alternative kindergarten interventions (5.0% vs. 10.5%, a 52% reduction). Participation for 4 to 6 years was significantly associated with lower rates of maltreatment (3.6% vs. 6.9%, a 48% reduction). Findings based on child protective service records (as well as combined protective service and court records) were similar. Preschool length, family risk, and school poverty were associated with lower rates of maltreatment. Parental involvement in school and school mobility were significant mediators of intervention effects.
