Evaluating quality of implementation in physical activity interventions based on theories of motivation: current challenges and future directions

The evidence base pointing towards the maladaptive health consequences of an inactive lifestyle highlights the need for interventions that are effective in changing and maintaining physical activity behaviours. Theories of motivation are frequently applied to inform the content and delivery of such interventions. Systematic monitoring and evaluation of the quality of intervention implementation is therefore an important step in understanding if and how theories of motivation can be adopted and effectively applied to promote and/or sustain physical activity behaviours. However, intervention implementation quality in studies that aim to apply motivation theory to promote physical activity is often under-reported. The purpose of this article is, first, to review contemporary approaches used to monitor and evaluate intervention implementation; we outline the degree to which these methods have been used effectively in research concerned with applying theories of motivation to impact physical activity behaviours. Second, we identify and discuss specific challenges in effectively measuring quality of implementation faced by researchers who adopt a motivation theory basis to their work. Finally, recommendations for methods to monitor and evaluate intervention implementation in future trials aiming to promote physical activity based on theories of motivation are also proposed.     

Effects of an Early Family Intervention on Children's Memory: The Mediating Effects of Cortisol Levels

Developmental psychologists have long been concerned with the ways that early adversity influences children's long-term outcomes. In the current study, activity of the hypothalamic–pituitary–adrenal axis of medically at-risk (e.g., preterm) infants was measured as a result of maternal participation in a novel cognitively based home visitation program (versus a Healthy Start home visitation program). Maternal participation in the cognitive intervention predicted lower basal cortisol levels among infants—with reduced levels of maternal avoidance/withdrawal serving as a mediator of this relation. Lower cortisol levels in infancy, in turn, predicted higher verbal short-term memory (STM) at age 3. STM represents a cognitive ability that has importance for children's later educational outcomes. Findings provide experimental evidence concerning the pathway by which an early intervention may produce hormonal changes that can, in turn, influence children's learning outcomes.

Nothing to Fear? An Analysis of College Students' Fear Experiences With Video Games

This study presents the results of a survey of 269 undergraduate students conducted to examine fright experiences caused by video games. Over half of the participants reported game-induced fear. Sex, sensation-seeking, and empathy all emerged as important individual differences in terms of enjoyment of frightening content, consumption of frightening content, and frequency of fright experience. Interactivity and presentations of realism also predicted fear. This work identifies titles, stimuli, and features that caused fright experience.     

Girls and science: A review of four themes in the science education literature

Despite valuable syntheses of the field of gender and science education, there has not been a systematic, comprehensive review of the literature on gender and science education in recent years. We examine the literature pertaining to girls' engagement in science and develop four themes (equity and access, curriculum and pedagogy, the nature and culture of science, and identity) that we believe provide a coherent picture of the different kinds of approaches happening currently, while at the same time allowing for discussion of how ideas in the field have progressed and changed over time. We present new questions and approaches for further research that arise when applying insights from these themes to ongoing work in gender and science education. © 2008 Wiley Periodicals, Inc.

Evaluating academic development in the higher education sector: academic developers’ reflections on using a toolkit resource

The professionalisation of teaching is of increasing importance in UK higher education due to converging processes including the proliferation of managerialism, increasing quality agendas and changes to student fee structures. These have brought into sharp relief the need for greater understanding of how quality teaching evolves in university settings. One key element of this involves academic development and its impacts on teaching and learning. Current literature suggests that a plethora of ideas, frameworks and instruments claiming best practice exist but that take-up of these is inconsistent. This prompted a UK national research project which produced an evidence-based toolkit for evaluating academic development. As part of the toolkit augmentation, academic development representatives from across the sector were asked to create, review and test uniquely tailored evaluation instruments. These instruments were then piloted on university teachers who had participated in teaching-related continuing professional development activities. This paper reports on these individuals’ reflections of using the toolkit. It suggests that academic developers are interested in evaluating the impact of their work on teachers, students and on the wider institutional culture but that confidence and expertise varies. Using the toolkit generated ‘traditional’ evaluation data including satisfaction with the development activity and changes to lecturers’ conceptions and behaviours. However, it also prompted critical discussions around current evaluation practice. This included the need for transformational reform of institutional culture to support links between evaluation and good standing; and making explicit the thorny issue of evidencing student learning. This paper will be of interest to those with an interest or responsibility for evaluating teaching in higher education. The paper offers an important contribution to the international literature at a time when global higher education is faced with questions about teaching, learning and quality. Evaluation, and how to do it well, is timely and important business.
