The Many Sides of QUBE: Interactive Television and Innovation in Electronic Media, 1977–1983

QUBE was an interactive cable television system that attracted significant attention when it launched in 1977. The service has been deemed a commercial failure, though many of its ideas foreshadowed current television practices. There is however no detailed study of QUBE, and previous scholarship provides limited information. Using Moran’s concept of an “evolution-revolution,” this study analyzes the content offerings of QUBE to reveal how they were similar, and how they differed, from prior practice. This historical inquiry fills a gap in the historical record, while also exploring the complex nature of innovation in the world of electronic media.     

The Role of Everyday Contexts in Learner‐centred Teaching: The practice in Namibian secondary schools

This paper reports on the use of out‐of‐school everyday contexts in Namibian science classrooms. This use is portrayed against the backdrop of an explicit educational philosophy of learner‐centred teaching. Data were collected through audio‐taped teacher–learner interactions and non‐participant field notes in 29 junior and senior science classes taught by 12 teachers in six schools. An existing typology was applied to classify episodes of use of everyday contexts and identify teachers’ pedagogic strategies for their use. The results show that more everyday contexts are used in junior secondary than in senior secondary classes, that only a limited range of types of everyday contexts are used at both levels, and that their use often follows theoretical exposition or teacher questioning. These findings are related to three interpretations of learner‐centred teaching. Recommendations for a fuller implementation of learner‐centred teaching are made.     

Did She Jump Because She Was the Big Sister or Because the Trampoline Was Safe? Causal Inference and the Development of Social Attribution

Children rely on both evidence and prior knowledge to make physical causal inferences; this study explores whether they make attributions about others' behavior in the same manner. A total of one hundred and fifty‐nine 4‐ and 6‐year‐olds saw 2 dolls interacting with 2 activities, and explained the dolls' actions. In the person condition, each doll acted consistently across activities, but differently from each other. In the situation condition, the two dolls acted differently for each activity, but both performed the same actions. Both age groups provided more “person” explanations (citing features of the doll) in the person condition than in the situation condition. In addition, 6‐year‐olds showed an overall bias toward “person” explanations. As in physical causal inference, social causal inference combines covariational evidence and prior knowledge.     

The Relation of Career Indecision and Parental Attachment among Iranian Undergraduate Students

Career indecision particularly among college and undergraduate students is a concern of counselors and psychologists. This concern has led to numerous research studies related to career indecision and factors that influence it, such as family relationships. In this regard, several studies have reported a significant relationship between career indecision and parental attachment. However, little research has been undertaken on the influence of this factor in regard to career indecision for Iranian students. For this purpose, 158 Iranian freshmen and sophomores who had completed the ‘Career Decision Scale’ (Osipow et al., Journal of Vocational Behavior 9:233–243, 1976) and had been identified as career-undecided, completed the ‘Inventory of Parents and Peer Attachment-Revised’ (Armsden & Greenberg, Journal of Youth and Adolescence 16:427–453, 1987). The results revealed that a significant negative relationship was found between career indecision and attachment to mother, whilst the relationship between career indecision and attachment to father was not significant. However, regression analysis showed parental attachment did not significantly predict career indecision of students. Implications and recommendations for further research are discussed.     

When does a nation-level analysis make sense? ESD and educational governance in Brazil,South Africa,and the USA

International policy analysis tends to simplify the nation state, portraying countries as coherent units that can be described by one statistic or placed into one category. As scholars from Brazil, South Africa, and the USA, we find the nation-centric research perspective particularly challenging. In each of our home countries, the effective influence of the national government on education is quite limited, particularly in fringe and emerging areas of education such as Education for Sustainable Development (ESD) and Climate Change Education (CCE). This essay explores how nation-level comparisons are and are not useful for international research on ESD and CCE. We consider several layers of decentralized governance, but ultimately come to the conclusion that ESD governance in our respective countries is polycentric rather than decentralized. We discuss the implications of this idea for cross-national policy research on ESD and CCE.     

Enacting culturally relevant pedagogy: asset mapping in urban classrooms

In an attempt to confront monolithic perceptions of achievement and an educational narrative that defines communities of Color by their supposed deficits, the current study presents asset mapping as an example of culturally relevant pedagogy in action. Asset mapping is a pedagogical tool for students to visually represent personalized stories of their cultural assets and participate in a community-based gallery walk to showcase their maps. Interviews and focus groups with third- and sixth-grade teachers and students from an urban public school revealed learning about self, learning about others, and building community as emergent themes after completing the project. We present these themes and discuss asset mapping as a possible model for strength-based pedagogy that centers the lived experiences of students, their families, and their shared stories in classroom curriculum.     

Studying and Constructing Concept Maps: a Meta-Analysis

A concept map is a node-link diagram in which each node represents a concept and each link identifies the relationship between the two concepts it connects. We investigated how using concept maps influences learning by synthesizing the results of 142 independent effect sizes (n = 11,814). A random-effects model meta-analysis revealed that learning with concept and knowledge maps produced a moderate, statistically significant effect (g = 0.58, p < 0.001). A moderator analysis revealed that creating concept maps (g = 0.72, p < 0.001) was associated with greater benefit relative to respective comparison conditions than studying concept maps (g = 0.43, p < 0.001). Additional moderator analyses indicated learning with concept maps was superior to other instructional comparison conditions, and was effective across science, technology, engineering, and math (STEM) and non-STEM knowledge domains. Further moderator analyses, as well as implications for theory and practice, are provided.
