A Framework for User Agency during Development of Interactive Risk Visualization Tools

ABSTRACT

Participating in user-centered design provides potential users of interactive risk visualization tools agency in influencing tool development. This article identifies and characterizes pathways for agency that users may experience as they participate in design of interactive tools for visualizing environmental risks. We present an empirically based conceptual framework for better understanding user agency during visualization tool development based on findings from interviews with professional visualization tool developers and discuss practical implications and future research recommendations.

Using three-dimensional interactive graphics to teach equipment procedures

This report focuses on how 3-D graphical and interactive features of computer-based instruction can enhance learning and support human cognition during technical training of equipment procedures (where procedural training tasks are often highly specific to a piece of equipment). Studies of the effects of graphics, motion, and interactivity in technical training, and reports of successful instruction using state-of-the art graphics and animation were reviewed to extract a set of guidelines for using 3-D interactive graphics to teach equipment procedures.The opinions and assertions are the authors' and should not be construed to represent that of the Navy Department or the Department of Defense.     

Learner agency and the curriculum: a critical realist perspective

Abstract

Agency, understood as the capacity to act independently and to make one’s own choices, is considered central to children’s development. Thus, education, and hence education curricula, have a role in the development of learner agency. While curriculum development is a key focus for educational theory, research, policy, and classroom practice, the potential implications of curriculum content selections for learner agency remain underexplored. Theoretically, this paper engages with critical realism, explaining how it can provide theoretical foundation for a more comprehensive view of learner agency and, by implication, more balanced curricula. Empirically, the paper draws on the findings from a content analysis of the national curriculum documents of four countries with relatively high scores in international comparative tables, England, Australia, Hong-Kong, and Canada, to develop a new typology of primary curricula. Based on the extent of emphasis placed on knowledge versus skills, values, and attitudes, three types of curricula were identified: knowledge-based, skills-oriented, and learner-centred. Due to its significant theoretical and practical influence globally, we focus on the knowledge-based model and its likely impact on students’ agency. We conclude by highlighting the importance of making learner agency a key orientation of the curriculum and suggesting directions for future research.     

‘I’ll take care of the flowers!’ Researching agency through initiatives across different learning environments

ABSTRACT

This case study examined how the agency of a fifth-grade pupil appeared across different learning environments in the primary school context. In this study, agency is defined as the initiatives taken by an individual in interactive situations. The research question is: how does a pupil’s agency manifest and vary through taking initiatives across different learning environments within curriculum-based education? The empirical data consist of 50 video episodes including learning activities in a classroom, in a vegetable garden and on a nearby farm. The findings show that the pupil’s agency varied across learning environments, manifesting itself through complementing, supportive, constructive and challenging initiatives. When developing pedagogy that supports learning across formal and informal learning environments, it is essential to enable pupils to take different kinds of initiatives and to exercise their agency in versatile contexts.     

Self-Regulation Mediates the Relationship between Learner Typology and Achievement in At - Risk Children

A person-centered approach was used to explore the mediating role of self-regulation between learner typology at age 8 and academic achievement at age 14while controlling for domain-specific achievement in a longitudinal sample of 113 children born to adolescent mothers. Children were classified into one of 5 learner typologies at age 8based on interactive patterns of intellectual, achievement, and adaptive abilities. Typology classification explained significant variance in both reading and mathematics achievement at age 14. A bootstrapping approach confirmed that self-regulation mediated the relationship between typology and reading and mathematical achievement for children from all typologies except those classified as Cognitively and Adaptively Challenged. Implications of person-centered approaches for understanding processes involved with achievement are discussed.

Learning Computer Graphics Using Virtual Reality Technologies Based on Constructivism – Case Study of the WebDeGrator System

This study applies constructivist principles and Virtual Reality (VR) technology to the Web-based Interactive Design Graphics (WebDeGrator) system to improve learning computer graphics. The constructivist treatment provides students with access to their choice of source content, three-dimensional (3D) modeling tools and interactive behaviors in a virtual environment. In this study, we developed a VR-based learning system to simulate and adjust computer graphics through sculpture graphic algorithms in real-time. We will discuss the relationship between constructivism and VR technology and also how the WebDeGrator system encourages student-learning through VR technology.     

Physically based modeling and animation of tornado

INTRODUCTIONTornado is one of the most terrible natural phe- nomena in the world. It causes incredible amounts of damage and destroys significant numbers of facilities every year. No wonder it receives great attention as a major research topic in many fields. Realistic simu- lation of tornado is also a great challenge for com- puter graphics researchers. It provides useful infor- mation for natural disaster prevention and can be integrated into entertainment, computer games, etc. Most to…     

Approaches to reflexivity: navigating educational and career pathways

This paper provides a critical appraisal of approaches to reflexivity in sociology. It uses data from social network research to argue that Archer’s approach to reflexivity provides a valuable lens with which to understand how people navigate their education and career pathways. The paper is also critical of Archer’s methodology and typology of reflexivity as ‘types’; it is argued that social network research suggests people reveal different approaches to reflexivity in different situations. It concurs with Archer that the concept reflexivity is central to our understanding of the relationships between agency, structure and social change

口头叙事与民间信仰:两种地方性知识的互文性——以乡村视野中的传说与信仰为例

对口头叙事和民间信仰的研究,学术界长期停留在民俗事象的历史演进范式和类型化处理,很少突破脱离情境的标本化。众多研究成果和事实表明,在地方性知识体系内,口头叙事在具体时空坐落中的民众和民众活动中生成、传播并获得意义,民众生活、心灵世界和信仰的内容也由传说建构和调适,从而形成一种互动的完整的社会性传承。由此,强调了纳入文化整体视野下建立二者的双向解释模式。
