THE IMPLEMENTATION OF NUFFIELD ‘O’ LEVEL CHEMISTRY COURSES IN SECONDARY SCHOOLS

A study of schools entering pupils for the examinations of the Nuffield ‘O’ level Chemistry project suggests that, as yet, such schools are located near the original centres of project activity. Comparison of the heads of the Chemistry departments in matched samples of ‘Nuffield’ and ‘non‐Nuffield’ schools (summer 1969), established no significant difference in academic and professional training or in experience of non‐classroom employment. Nuffield Chemistry schools were found to have a larger percentage of pupils following sixth form science courses but the difference in annual, per capita expenditure on Chemistry teaching was significant only at the five per cent level.     

Methodological and Ethical Dilemmas in International Research: school attendance and gender in Ghana

abstract

The paper considers questions of ethics and methodology in international research. An action research project designed for Ghana/UNICEF as part of a consultancy on school attendance is used as a case‐study from which to examine the ethical dilemmas facing consultants and their clients in educational research carried out as part of international aid. Ethical dilemmas of resourcing, ownership, accountability and self‐interest are discussed by the English consultants. It thus has a double purpose. It both contributes to research on school attendance, and also furthers debate about methodology and constraints on it.     

Using social stories to decrease aggression and increase positive peer interactions in normally developing pre‐school children

Social stories have been widely used for children with autism and developmental delays; however, little research has been conducted that examines their effectiveness with pre‐school children who have no developmental delays. The present study investigated this previously undocumented use of social stories. Social stories were used to decrease aggression and improve positive peer relations in a Head Start pre‐school setting. Participants included three four‐year‐old pre‐school students. A single‐subject, ABC multiple baseline design with counterbalanced treatment order was implemented where social stories were compared to a neutral book. Direct observations and pre‐ and post‐Behaviour Assessment System for Children‐2 (BASC‐2) Teacher Rating Scale (TRS) scores were examined. Results revealed some support for the usefulness of social stories in this setting and with this population. Limitations of the study are discussed and directions for future research are provided.     

Developing teachers’ knowledge of students as learners of mathematics through structured interviews

A structured interview process is proffered as an effective means to advance prospective teachers’ understandings of students as learners of mathematics, a key component of pedagogical content knowledge. The interview process is carried out in three phases with the primary objective of developing listening skills for accessing students’ mathematical thinking. The interviews adhere to clinical interview procedures for discovering cognitive activities and, accordingly, are initiated by presenting an open-ended mathematics task. Three rounds of interviews were completed by undergraduates enrolled in a middle school mathematics methods course. Anecdotal data generated by their interview reports suggest that the structured interview process engenders an interpretive orientation to listening to students and furthers awareness of how students make sense of mathematics. Features of the interview process that may limit its potential benefits are discussed; recommendations for further study are proposed.     

Educational psychologists and children in care: practices and issues

The aims of this study were to examine the extent and nature of educational psychologist (EP) work related to children in care in five local authority educational psychology services in the south‐west region. The study involved an initial internet‐based questionnaire for the 107 EPs in these services (86% response rate), followed up by in‐depth semi‐structured interviews with four EPs in each service. This paper reports some of the findings from this study that show the range of EP work and their roles in regard to children in care. It also examines the kinds of issues and tensions experienced by EPs in their multi‐agency work with regards to children in care. The paper concludes with a brief summary of relevant recommendations arising from the findings.     

Training rugby athletes with an external attentional focus promotes more automatic adaptions in landing forces

Training to reduce landing forces is a common component of anterior cruciate ligament injury prevention programmes. The purpose of this study was to compare the effects of training incorporating instructions promoting an internal versus external attentional focus on landing forces in adolescent rugby athletes. Twenty-two rugby athletes were randomly allocated to groups that received instructions promoting an internal versus an external focus during a two week training programme. Landing forces were recorded before and after completion of the programme. During follow-up testing, landings were performed with and without a secondary cognitive task. Both groups exhibited a similar reduction in landing forces following training for trials performed without the secondary cognitive task. However, the groups responded differently when the secondary cognitive task was imposed. Athletes who were trained with an internal focus demonstrated a prominent increase in landing forces for trials that included the secondary cognitive task (vs. trials performed without the secondary cognitive task), whereas the secondary cognitive task had minimal influence for athletes who were trained with an external focus. It appears that training with an external focus may promote adaptations in landing mechanics that can be implemented more automatically.     

Documentation for institutional repositories

The documentation of seven academic institutional repositories (IRs) was compared and contrasted. This was followed by semi‐structured interviews with six practitioners experienced in the set‐up, management and maintenance of IRs, including representatives of three JISC FAIR projects. The aim was to identify the requirements of policy documentation provided by IRs. Although many issues were found to be handled differently, several common factors emerged. These included the importance of developing documentation in collaboration with academics, departments and senior management. Policies should be formulated only when the aims of the IR have been clearly defined and the documentation itself should be concise and understandable, with the rights and responsibilities of stakeholders clearly presented.     

Effect of the movement speed of resistance training exercises on sprint and strength performance in concurrently training elite junior sprinters

The aim of this study was to determine the effects of 7 weeks of high- and low-velocity resistance training on strength and sprint running performance in nine male elite junior sprint runners (age 19.0+/-1.4 years, best 100 m times 10.89+/-0.21 s; mean +/- s). The athletes continued their sprint training throughout the study, but their resistance training programme was replaced by one in which the movement velocities of hip extension and flexion, knee extension and flexion and squat exercises varied according to the loads lifted (i.e. 30-50% and 70-90% of 1-RM in the high- and low-velocity training groups, respectively). There were no between-group differences in hip flexion or extension torque produced at 1.05, 4.74 or 8.42 rad x s(-1), 20 m acceleration or 20 m 'flying' running times, or 1-RM squat lift strength either before or after training. This was despite significant improvements in 20 m acceleration time (P < 0.01), squat strength (P < 0.05), isokinetic hip flexion torque at 4.74 rad x s(-1) and hip extension torque at 1.05 and 4.74 rad x s(-1) for the athletes as a whole over the training period. Although velocity-specific strength adaptations have been shown to occur rapidly in untrained and nonconcurrently training individuals, the present results suggest a lack of velocity-specific performance changes in elite concurrently training sprint runners performing a combination of traditional and semi-specific resistance training exercises.
