Images of science teaching: An exploration of the beliefs of preservice secondary science teachers

Science graduates who enrol in a preservice Graduate Diploma of Education bring with them many years of experience as learners of science. These will have enabled them to develop implicit theories about what a science teacher is and does. Such implicit theories almost certainly affect the process of becoming a teacher, and may prove persistent despite the input from University and school during the Dip. Ed. year and beyond. This paper presents the research method and results obtained from a group of graduates on entry to their Diploma course. Concept maps and Repertory Grid interviews were obtained from eleven graduates, with varying life experiences. The paper presents analyses of these and explores emerging themes. Specializations: reflective teaching, general science and biology, curriculum and assessment.     

Teachers’ perceptions of disruptive behaviour in schools: a psychological perspective

This article reports on an investigation into school teachers’ perceptions of disruptive behaviour from a psychological perspective. The inter-disciplinary nature of this research bridges the understanding between educational and psychological perspectives on disruptive behaviour. This article discusses evidence that for the most troubled pupils, effective behaviour management at school necessitates a more nurturing and collaborative approach alongside current disciplinary policy. Two studies are reported which examine teachers’ perceptions of disruptive behaviour at school. Discussion focuses on findings of a postal questionnaire sent to 426 primary and secondary schools across England, regarding teachers’ perceptions on the extent to which pupils can control their disruptive behaviour. A further 122 primary schools were sent the questionnaire via SurveyMonkey. The findings illustrate that there is variation in how teachers in primary and secondary schools regard their pupils’ behaviour. Implications of the findings are discussed with reference to attachment theory.     

The application of a multi-dimensional assessment approach to talent identification in Australian football

ABSTRACT

This study investigated whether a multi-dimensional assessment could assist with talent identification in junior Australian football (AF). Participants were recruited from an elite under 18 (U18) AF competition and classified into two groups; talent identified (State U18 Academy representatives; n = 42; 17.6 ± 0.4 y) and non-talent identified (non-State U18 Academy representatives; n = 42; 17.4 ± 0.5 y). Both groups completed a multi-dimensional assessment, which consisted of physical (standing height, dynamic vertical jump height and 20 m multistage fitness test), technical (kicking and handballing tests) and perceptual-cognitive (video decision-making task) performance outcome tests. A multivariate analysis of variance tested the main effect of status on the test criterions, whilst a receiver operating characteristic curve assessed the discrimination provided from the full assessment. The talent identified players outperformed their non-talent identified peers in each test (P < 0.05). The receiver operating characteristic curve reflected near perfect discrimination (AUC = 95.4%), correctly classifying 95% and 86% of the talent identified and non-talent identified participants, respectively. When compared to single assessment approaches, this multi-dimensional assessment reflects a more comprehensive means of talent identification in AF. This study further highlights the importance of assessing multi-dimensional performance qualities when identifying talented team sports.     

Preservice Teachers' Knowledge of Difficulties in Decimal Numeration

In this study we investigated preservice elementary school teachers' content knowledge and pedagogical content knowledge of decimal numeration. The preservice teachers completed a decimal comparison test, marked items they thought would be difficult for students, and explained why. Only about 80 percent of the sample tested as experts, indicating that a significant proportion of preservice teachers have inadequate content knowledge of decimals. Confusion about the size of decimals in relation to zero was a significant and unexpected difficulty, leading to concerns about the fragmentary nature of the preservice teachers' knowledge. Most preservice teachers were aware of longer-is-larger misconceptions in students, but had little awareness of shorter-is-larger misconceptions. Preservice teachers' explanations for the reasons students might have difficulty demonstrated that many are good at identifying features that make comparisons difficult but less able to explain why these cause trouble. Results point to the need for teacher education to emphasise content knowledge that integrates different aspects of number knowledge, and pedagogical content knowledge that includes a thorough understanding of common difficulties. This revised version was published online in August 2006 with corrections to the Cover Date.

On the association between serial naming speed for letters and digits and word‐reading skill: towards a developmental account

The current study examined several alternative explanations of the association between serial naming speed within fourth‐grade children by determining the extent to which the association between word reading and naming speed for letters and numbers is mediated by global processing speed, alphanumeric symbol processing efficiency and phonological processing ability. Children were given multiple measures of key constructs, i.e. word‐level reading, serial naming of both alphanumeric and non‐alphanumeric items, phonological processing ability, articulation rate and global processing speed. The robust association between alphanumeric naming speed and reading within fourth‐grade children was largely mediated by phonological processing ability. Markedly different patterns of results were observed for naming speed for letters and digits and naming speed for colours and pictures in children of this age. Relative to the latter, alphanumeric naming speed better assesses an underlying phonological processing ability that is common to word‐reading ability. We argue that item identification processes contribute little to individual differences in alphanumeric naming speed within relatively proficient readers and that the extent to which alphanumeric naming speed primarily reflects phonological processing is likely to vary with the level of overlearning of letters and numbers and their names.     

A good measure of safety

Each year, fifteen thousand children die from accidents—more than from cancer, congenital malformations, pneumonia, heart disease, meningitis, and homicide combined. As a day care center provider or a parent, you are responsible for the safety and well-being of children in your care. You need to know how to make your home safe for children and how to prevent accidents. Young children view things as interesting to taste or touch—not as safe or dangerous. Children do not even begin to understand the concept of danger until the age of two. Protecting them is your job.

A comparison of the Stanford-Binet Intelligence Scale and the McCarthy Scales of Children's Abilities with preschool children

The purpose of the present study was to determine the degree to which performance on the McCarthy Scaies of Children's Abilities correlated with performance on the Stanford-Binet for a group of preschoolers. The sample consisted of 44 children ranging in age from 3–11 to 5–4. It was found that the General Cognitive Index scores of the McCarthy Scales correlated well with the Stanford-Binet IQ scores, r^xy = .90. However, 40 of the 44 subjects scored higher on the Stanford-Binet than on the McCarthy Scales.
