Small Robot Projects: Before You Start

Working with robots is an attractive possibility for educators at many levels. The price and availability of robotic hardware are favorable, there are often examples in the media of school groups doing robotic projects, and the projects support group design and co-operative activity. Still, these projects cannot be organized without considerable effort. In this article, we look at some of the opportunities and pitfalls that are encountered when working with robots in an educational setting, illustrating them with anecdotes from our experience with eight small robot-building projects, with participants ranging in age from nine to adult, and duration ranging from a single day to a full semester. We suggest some of the benefits of these projects and outline the problems organizers and participants will be likely to face.     

The effect of ball carrying method on sprint speed in rugby union football players

Different methods of ball carrying can be used when a player runs with the ball in rugby union. We examined how three methods of ball carrying influenced sprinting speed: using both hands, under the left arm and under the right arm. These methods were compared with running without the ball. Our aim was to determine which method of ball carrying optimizes sprinting speed. Altogether, 48 rugby union players (age 21 +/- 2 years, height 1.83 +/- 0.1 m, body mass 85.3 +/- 12 kg, body fat 14 +/- 5%; mean +/- s) were recruited. The players performed twelve 30-m sprints in total (each player performed three trials under each of three methods of carrying the ball and sprinting without the ball). The design of the study was a form of Latin rectangle, balanced across the trial order for each of the methods and for pairwise combinations of the methods in blocks of four per trial. Each sprint consisted of a 10-m rolling start, followed by a 20-m timed section using electronic timing gates. Compared with sprinting 20 m without the ball (2.58 +/- 0.16 s), using both hands (2.62 +/- 0.16 s) led to a significantly slower time (P < 0.05). Sprinting 20 m with the ball under the left arm (2.61 +/- 0.15 s) or under the right arm (2.60 +/- 0.17 s) was significantly quicker than when using 'both hands' (P < 0.05), and both these methods were significantly slower than when running without the ball (P < 0.05). Accordingly, running with the ball in both hands led to the greatest decrement in sprinting performance, although carrying the ball under one arm also reduced the players' sprinting ability. Our results indicate that to gain a speed advantage players should carry the ball under one arm.     

Infant Attachment Security and Early Childhood Behavioral Inhibition Interact to Predict Adolescent Social Anxiety Symptoms

Insecure attachment and behavioral inhibition (BI) increase risk for internalizing problems, but few longitudinal studies have examined their interaction in predicting adolescent anxiety. This study included 165 adolescents (ages 14–17 years) selected based on their reactivity to novelty at 4 months. Infant attachment was assessed with the Strange Situation. Multimethod BI assessments were conducted across childhood. Adolescents and their parents independently reported on anxiety. The interaction of attachment and BI significantly predicted adolescent anxiety symptoms, such that BI and anxiety were only associated among adolescents with histories of insecure attachment. Exploratory analyses revealed that this effect was driven by insecure‐resistant attachment and that the association between BI and social anxiety was significant only for insecure males. Clinical implications are discussed.     

Using Vygotsky’s zone of proximal development to propose and test an explanatory model for conceptualising coteaching in pre-service science teacher education

Coteaching offers a model for the school-placement element of pre-service science teacher education, based on its demonstrated positive impacts on lessening classroom anxiety, supporting inquiry-based science teaching, improving students’ attitudes, and addressing diversity effectively in science classrooms. Coteaching between pre-service and in-service teachers is used to lessen the gap between theory and practice, to develop reflective practice and to develop pedagogical content knowledge. Explanatory frameworks have been proposed for coteaching, and we suggest that Vygotsky’s zone of proximal development helps to propose a more nuanced developmental and learning explanatory framework which provides pedagogical structures for implementation and highlights the importance of the social environment for learning. In providing structure and tools for effective implementation of coteaching, our model addresses three core elements of coteaching: coplanning, copractice, and coevaluation. The model was piloted in relation to pre-service teachers’ development in reflective practice and reducing the gap between theory and classroom practice.     

‘I just want to watch the match’: a practitioner’s reflective account of men’s health themed match day events at an English Premier League football club

This study reflects on the effectiveness and delivery of a series of health themed match day events at an English Premier League Football Club which aimed to create awareness and motivate men to adopt recommended health behaviours. A range of marketing techniques and activities were adopted within a targeted space and time to increase men’s exposure to health information. The first author adopted a practitioner-cum-researcher role and was immersed in the planning and delivery of the events utilising the principles of ethnography. Data were predominately collated through observations and personal reflections logged via autobiographical field notes. Data were analysed through abductive reasoning. In general, men were reluctant to engage in health-related behaviours on match days. However, subtle, non-invasive approaches were deemed successful. Positive outcomes and case studies from the latter techniques are presented and suggestions for effective strategies that will better engage men in health information and behaviours are made.
