Mathematical Modeling in the Primary School: Children's Construction of a Consumer Guide

This paper examines 6th grade children's local conceptual development and mathematization processes as they worked a comprehensive mathematical modeling problem (creating a consumer guide for deciding the best snack chip) over several class periods. The children and their teachers were participating in a 3-year longitudinal teaching experiment in which sequences of mathematical modeling problems were implemented from the 5th grade (10 years of age) though to the 7th grade. In contrast to traditional problem solving, mathematical modeling requires children to generate and develop their own mathematical ideas and processes, and to form systems of relationships that are generalizable and reusable. Reported here is a detailed analysis of the iterative cycles of development of one group of children as they worked the problem, followed by a summary of the mathematization processes displayed by all groups. Children's critical reflections on their models are also reported. The results show how children can independently develop constructs and processes through meaningful problem solving. Children's development included creating systems for operationally defining constructs; selecting, categorizing, and ranking factors; quantifying quantitative and qualitative data; and transforming quantities.     

Evaluating efforts to enhance health and wellbeing in Scottish secondary schools

Curriculum for Excellence in Scotland outlines a policy vision of a more progressive, integrated and holistic form of education; a commitment which contains an obligation for health and well-being (HWB) to be a responsibility of all teachers. A critical policy analysis approach was utilized in order to review school-level progress in different stages of policy development, i.e. policy formulation, legitimation, implementation and evaluation. Evidence was collected through 15 semi-structured interviews with head teachers, teacher education academics and staff with national and local authority quality improvement remits. Questions focused on: aims and curriculum goals; school culture; learning and teaching; partnership relationships and evaluations of practice. Findings suggest a high degree of support for curriculum aims, however, there were often problems communicating policy expectations (policy formulation). Thus, despite impressive examples of innovative practice in relation to school ethos, wider achievement and pupils’ broader general education (policy legitimation), there were also examples of HWB being constrained by senior school examinations and the backwash effect this had on curriculum planning and engagement with interdisciplinary learning approaches (policy implementation/evaluation). These findings have implications in terms of policy to practice coherence as well as highlighting the need for further more specific research evaluations.

实施《体育与健康课程标准》的教学策略研究

传统的体育教学策略形成了一种固有模式，它是紧紧围绕教材进行的，各个学段的设计既可以具有相关因素，也可以互不相关。而在《体育与健康课程标准》中体现的现代体育教学策略关注的是学生在教学活动中的思维变化过程，强调课程结构的完整性与呼应性，整个教学活动的设计是连贯的、递进的。前后比较，显现了新旧教学策略的差异性。
