The objective of this article is to offer guidelines regarding the selection, calculation, and interpretation of effect sizes (ESs). To accomplish this goal, ESs are first defined and their important contribution to research is emphasized. Then different types of ESs commonly used in group and correlational studies are discussed. Several useful resources are provided for distinguishing among different types of effects and what modifications might be required in their calculation depending on...

It was found that the majority of the listeners possessed radio sets and was getting benefit from the educational programmes of radio. The programmes were informative and motivating. The strategies of radio for rural education were appreciable because these infused mobility, widened horizon of rural people and focused attention on the goals and problems of rural people.

This paper explores a case of teacher professional development in Botswana, where a blended learning solution was attempted. The analysis of the implementation environment reveals deficiencies in policy, schools (workplaces), and training providers. The paper concludes with three recommendations: 1) Schools should support on-going teacher learning in the workplace and should manage ICT resources for use by both teachers and students; 2) Government should support participatory and localised...

As investments in K–12 math and science professional development programs expanded over the past decade, researchers and policymakers have questioned whether and how such programs work to improve student learning. This article summarizes the current knowledge-base and offers a theoretical framework researchers can use to design studies that explore mechanisms through which professional development programs influence teacher knowledge, teacher practices, and ultimately student achievement. We...

The increasing use of stakeholder analysis in natural resource management reflects a growing recognition that stakeholders can and should influence environmental decision making. Stakeholder analysis can be used to avoid inflaming conflicts, ensure that the marginalization of certain groups is not reinforced, and fairly represent diverse interests. We present a case study from the Peak District National Park in the United Kingdom, where we used social network analysis to inform stakeholder...

Worldwide, there is an emerging interest in sustainability and sustainability education. A popular and promising approach is the use of systems thinking. However, the systems approach to sustainability has neither been clearly defined nor has its practical application followed any systematic rigor, resulting in confounded and underspecified recommendations. The purpose of this article is to extend the notion of systems thinking as it pertains to sustainability pedagogy. The authors draw from...

Using a popularized notion such as Web 2.0 limits research efforts by employing a binary construct, one initially prompted by commercial concerns. Instead, the authors of this article, commenting on Greenhow, Robelia, and Hughes (2009), suggest that continuous, not dichotomous, change in the technologies of literacy and learning defines the Internet. They argue that a dual-level theory of New Literacies is a productive way to conceptualize this continuous change, especially for education....

This article focuses on the challenges involved in conducting evaluations of interactive radio programmes in South Africa with large numbers of schools, teachers, and learners. It focuses on the role such large‐scale evaluation has played during the South African radio learning programme’s development stage, as well as during its subsequent sustained implementation phase. The model evolved for evaluation of interactive radio instruction is based within the context of a shoestring/real‐world...

This article examines recent educational reforms in Tanzania by looking at the cultural politics of pedagogical change in secondary and teacher education. It presents an ethnography of a teachers college founded on the principles of social constructivism in a country where formalistic, teacher-centered pedagogy is the norm. Using data collected through a year of participant observation, it argues that the cultural, economic, and political dimensions of teachers’ practice need to be...
