There is evidence that contact with the natural environment and green space promotes good health. It is also well known that participation in regular physical activity generates physical and psychological health benefits. The authors have hypothesised that ‘green exercise’ will improve health and psychological well-being, yet few studies have quantified these effects. This study measured the effects of 10 green exercise case studies (including walking, cycling, horse-riding, fishing, canal-boating and conservation activities) in four regions of the UK on 263 participants. Even though these participants were generally an active and healthy group, it was found that green exercise led to a significant improvement in self-esteem and total mood disturbance (with anger-hostility, confusion-bewilderment, depression-dejection and tension-anxiety all improving post-activity). Self-esteem and mood were found not to be affected by the type, intensity or duration of the green exercise, as the results were similar for all 10 case studies. Thus all these activities generated mental health benefits, indicating the potential for a wider health and well-being dividend from green exercise. Green exercise thus has important implications for public and environmental health, and for a wide range of policy sectors.

Standards referenced reform, tied to reporting, engages directly with assessment issues related to accountability. Assessment is the key to good education and is inseparable from curriculum. In an accountability context, standards are used as a lever to improve the reliability and consistency of teacher judgement; and classroom evidence is used by education systems for reporting and tracking achievement over time. Assessment is thus a powerful driver for change and is at the heart of the teaching-learning dynamic. The relationship between the learner, learning and assessment needs to be kept central and the idea of teacher empowerment is fundamental. This chapter is a call to honour and sustain teacher professionalism through educative forms of school-based and teacher-led evaluation, assessment and communities of judgement practice. It supports the argument for a central place for classroom assessment in the role of assessment in educational accountability...
