Designing schools for quality: An international,case study-based review

Universal access to primary schools is a key millennium development goal, still proving difficult to deliver in low-income countries. Schools designed for the poorest remain inadequate for the numbers enrolled, and for the basic needs and functions of today’s classrooms. The key issue is overcrowding; classrooms designed for forty regularly accommodate more than sixty due to the use of outdated international classroom design standards. These schools also have poor access to infrastructure; electricity, drinking water, sanitation, and ICT/library spaces. This paper highlights these issues and suggests strategies for improved school design through the evaluation the EdQual research project school case studies, the author was involved with, and also recent international examples It is argued that schools designed considering these issues, can become ‘hubs’ for development; providing local assets that can be shared by their communities.     

A rapid screening measure for the identification of visuospatial learning disability in schools

Verbal and nonverbal forms of developmental learning disabilities have been reported. Whereas there are several instruments for evaluating children for the presence of verbal learning disabilities at school, no screening tool is available to identify children who have nonverbal learning disabilities. This study aimed at devising and validating a short screening questionnaire that can be used by teachers in primary schools to identify those children who need to be referred for clinical services because they have a visuospatial learning disability (VSLD). An 18-item Shortened Visuospatial Questionnaire (SVS) was derived from an earlier, longer version. Its validation procedure was twofold and was achieved by (a) verifying that children who had been identified with the SVS questionnaire as having a VSLD actually showed visuospatial deficits on psychometric evaluation and by (b) rating with the SVS a clinically identified population of children with VSLD. The results of the validation procedure showed that the SVS is a quick, reliable, and valid instrument that may be helpful in identifying children with VSLD in primary school.

对中小学择校问题的再思考

对于中小学择校现象应当重新予以认识。择校是指人们对就读学校的选择,在当前具有合理性和必然性。目前择校主要有以分择校、以权择校和以钱择校等三种形式。合理的择校应当以学生的素质为依据,同时视学校的具体情况确定招收择校生的数量及收费标准。择校既具有积极的意义,也有一定的负面影响。解决择校问题要从政府、社会和学校等多方面着手。     

Designing a curriculum model for the teaching of the Bible in UK Jewish secondary schools: a case study

This paper describes the process of designing a curriculum model for Bible teaching in UK Jewish secondary schools. This model was designed over the period 2008–2010 by a team of curriculum specialists from the Jewish Curriculum Partnership UK in collaboration with a group of teachers from Jewish secondary schools. The paper first outlines the context of UK Jewish secondary schools and then the curriculum context in which this specific model was designed. It then details the model itself and concludes with a discussion of the implementation of the model and associated challenges.     

Designing an effective sexuality education curriculum for schools: lessons gleaned from the South(ern) African literature

Sexuality education forms part of the national school curricula of most sub-Saharan African countries, yet risk-related sexual behaviour among young people continues to fuel the HIV pandemic in this part of the world. One of the arguments put forward to explain why sexuality education seems to have had little impact on sexual risk-taking is that existing curricula have neglected to take into account the complexity of the social, cultural and gender norms that influence the behaviour of school-going young people in sub-Saharan Africa. Over the past few years, the Department of Basic Education in South Africa has recognised the need to provide guidance to teachers on the content, pedagogical processes and messages that are relevant to their specific context. This paper critically reflects on findings from a literature-based study conducted to identify the cognitive and social factors influencing the behaviour of school-going young people in South Africa and the risk and protective factors that might be particular to their circumstances. The findings provide helpful guidelines about the development, content and implementation of sexuality education curricula more likely to be relevant in contexts of serious poverty and disadvantage. Although based on the South African literature, the findings may also offer useful lessons for curriculum designers in other developing countries.     

Designing Science Learning with Game-Based Approaches

Given the growing popularity of digital games as a form of entertainment, educators are interested in exploring using digital games as a tool to facilitate learning. In this study, we examine game-based learning by describing a learning environment that combines game elements, play, and authenticity in the real world for the purpose of engaging students’ learning of science and enhancing student motivation. We discuss the design of the environment and present research conducted. Our findings demonstrate that the design of an engaging, interactive environment using a game-based approach can help students have fun while learning.
