Homelessness in the elementary school classroom: social and emotional consequences

This study examined elementary school teachers’ experiences working with homeless students. Specifically, we focused on the psychosocial impacts of homelessness on students and their teachers. Qualitative, semi-structured interviews were conducted with 28 teachers who worked at designated public schools for family homeless shelters. A prominent theme that emerged from teachers’ accounts was how the instability tied to homelessness affected students’ behavioral, social, and emotional adjustment in the classroom (e.g. externalizing problems, difficulty developing peer relationships, and withdrawn behavior). Teachers’ own social and emotional competencies (e.g. fostering positive teacher–student relationships, and perspective taking) influenced the manner in which they responded to their students’ needs. Findings suggest that critical components may be lacking articulation in the McKinney-Vento Act’s Education for Homeless Children and Youth Program such as guidelines for teacher responsibilities, supports for teachers, and an emphasis not only on children’s academic but also social and emotional needs.     

Unexpected Poor Comprehenders Among Adolescent ESL Students

This study explored characteristics of reading comprehension difficulties among Chinese students learning English as a second language (ESL). Two hundred forty-six Grade 8 English-immersion students in China were administered a battery of reading-related and reading comprehension tests. Three groups of comprehenders matched on age, nonverbal intelligence, and word-reading speed were identified: unexpected poor comprehenders, expected average comprehenders, and unexpected good comprehenders. The three groups differed in vocabulary and higher level processes. Vocabulary breadth and depth distinguished between the unexpected poor comprehenders and the expected average comprehenders. Inference, strategy, listening comprehension, summary writing, and morphological awareness distinguished between the expected average comprehenders and the unexpected good comprehenders. The findings suggest that vocabulary is the main source of reading comprehension difficulties in ESL unexpected poor comprehenders. The advantage of the unexpected good comprehenders group is primarily due to discourse comprehension and strategic processes, and is only possible with high language proficiency. There is no evidence that ESL unexpected poor comprehenders have poor Chinese (L1) reading ability.     

Do teachers know more about specific learning difficulties than general practitioners?

In this article, Dr Amanda Kirby, medical director at the Dyscovery Centre in Cardiff, Rhys Davies, a researcher for the School of Education at the University of Wales, and Amy Bryant, a psychology student at Cardiff University, report on their investigations into teachers' and general practitioners' (GPs') knowledge of six specific learning difficulties. It was hypothesised that the knowledge of both groups would be similar. The recent development of a labelling culture has resulted in confusion over the terms and the actual difficulties encountered by the individual. The authors asked 105 teachers and 105 GPs to define six categories of learning difficulties (dyspraxia; developmental co-ordination disorder (DCD); attention deficit disorder (ADD); deficit in attention, motor control and perception (DAMP); Asperger's syndrome; and dyslexia) on a questionnaire.
The teachers gave significantly more correct definitions than the GPs. However, knowledge from both professional groups was limited, with correct responses only demonstrating a cursory awareness. There are implications for both groups of professionals. Teachers will not be able to recognise or accommodate the child with learning difficulties in class if their knowledge is limited. Similarly GPs will find it difficult to detect and appropriately refer children with learning difficulties. Finally, and most importantly, there are implications for the identification and support of the child, in both the short term and the long term, and associated psychological issues such as lowered self-esteem, depression and anxiety. Amanda Kirby, Rhys Davies and Amy Bryant make suggestions for improving the level of knowledge among professionals through training and discuss, in this engaging and frequently amusing article, some of the issues surrounding the current labelling system.     

AD/HD: The role of teachers in the assessment of children suspected of having AD/HD

In the light of recent guidance published by The National Institute for Health and Clinical Excellence (NICE) on the diagnosis and management of attention deficit disorders in children, young persons and adults, Gill Salmon, a consultant Child and Adolescent Psychiatrist based in Swansea, South Wales, and Amanda Kirby, Professor of Developmental Disorders in Education based at the University of Wales, Newport, give an overview of the rationale for involving teachers in the assessment of children with AD/HD and the development and implementation of subsequent educational interventions. They also review the resulting training implications; explore some of the obstacles to multi‐agency, multi‐disciplinary working; and examine how current special educational needs policy goes hand‐in‐hand with the tiered approach to provision of child and adolescent mental health services in offering a graduated response to these children.     

The influence of the site of sampling and assay medium upon the measurement and interpretation of blood lactate responses to exercise.

This paper reports the findings of two investigations into methodological problems associated with the interpretation of blood lactate (BLa) in the sports sciences. In Experiment 1, brachial artery (A), antecubital venous (V) and fingertip capillary (C) blood samples were drawn simultaneously from nine subjects (mean age 21.1 +/- 1.3 years) during an incremental treadmill protocol and immediately assayed for BLa concentration. Experiment 2 investigated the extent of lactate concentration differences in whole blood (WB), lysed blood (LB) and plasma (P) measured using a YSI 23 AM analyser. In Experiment 1, a comparison of the mean BLa concentrations obtained from the three sites revealed no significant differences (P greater than 0.05). Correlations between BLa samples from different sites were very high, with r values ranging from 0.858 to 0.983. In Experiment 2, the mean lactate concentrations were: WB, 4.7 +/- 2.7 mM; LB, 5.0 +/- 3.0 mM; P, 7.0 +/- 3.8 mM. Plasma (P) values were significantly higher than WB and LB. Values from all sites were highly correlated with coefficients ranging from 0.963 to 0.987. In conclusion: (1) Significant arterial and venous BLa concentration differences do not exist during incremental treadmill exercise. (2) As capillary BLa concentrations reflect arterial values, their use in laboratory and field settings is recommended. (3) Lactate concentration differences in whole blood, lysed blood and plasma will influence the assessment of performance at fixed lactate reference values. (4) If the inter-laboratory test procedures are to be standardized and results compared, precise reporting of lactate sampling and assay techniques is critical.     

Effects of strategy training on Progressive Matrices performance

Two qualitatively different information-processing algorithms for solution of Raven's Progressive Matrices items have been identified. Whereas the Gestalt algorithm involves spatial operations upon the test stimuli, the Analytic algorithm employs logical operations upon features abstracted from the displays. In this study, training groups were established varying both in the Strength (Weak or Strong) and Type (Gestalt or Analytic) of training at three grade levels. Two sets of post-test measures were given. Ambiguous items were constructed such that more than one correct answer was possible, some being the result of the Gestalt algorithm and others of the Analytic algorithm. Subjects' performances on the Ambiguous items indicated that strong Analytic training had been particularly effective and was specific to Analytic answer options. The second post-test measure was Set I of the Advanced Progressive Matrices. Performance on these Test items indicated that the effects of strategy training had been maintained, and were due to the facilitation of Analytic item performance by Analytic training. The effects of Strength and Type of training were consistent across Grades. These results support Hunt's analysis of Raven's Progressive Matrices items, and demonstrate that strategy training based upon a precise information processing task analysis can be effective in improving Progressive Matrices performance. The implications of these results for intellectual assessment are discussed.     

The making of Mark Rothko's Harvard Murals

Mark Rothko's Harvard Murals are a series of paintings on canvas commissioned by Harvard University and created in the early 1960s. The present study investigates Rothko's creative process, materials, and technique with ultraviolet and infrared imaging, analytical chemistry, cross-sectional analysis, and comparisons with the literature. Infrared and Raman spectroscopy imaging of cross sections help with the chemical mapping of the paint stratifications. A comparison of paper studies, studies on canvas, and the final five works installed give a detailed insight into Rothko's editing process. The intimate relationship between works on paper and canvas is traced by uncovering a back and forth between the two media, and the mixing of dry pigment with binder is a common theme for works on both supports. Motif developments, changes, and distinct painting campaigns become apparent with ultraviolet induced visible fluorescence imaging and infrared reflected infrared digital photography. Color measurements and microfading experiments give insight into the stability and light sensitivity of the materials used by Rothko in the Harvard Murals.     

Teachers’Choice of Storybooks: What Messages do Children Hear?

An important dimension to the teaching of literacy must be the quality of the texts provided for children to read. The features of reading texts in schools have only recently become the object of sustained inquiry but it appears there are some interesting issues in the different perceptions children and teachers may have of these texts. Phil Kirby explores some of these issues in this article and provides excellent evidence that choice of story books is not the simple issue it might appear.
