Expertise Differences in the Comprehension of Visualizations: a Meta-Analysis of Eye-Tracking Research in Professional Domains     

Andreas Gegenfurtner  Erno Lehtinen  Roger S?lj? 《Educational Psychology Review》2011,23(4):523-552

This meta-analysis integrates 296 effect sizes reported in eye-tracking research on expertise differences in the comprehension of visualizations. Three theories were evaluated: Ericsson and Kintsch’s (Psychol Rev 102:211–245, 1995) theory of long-term working memory, Haider and Frensch’s (J Exp Psychol Learn Mem Cognit 25:172–190, 1999) information-reduction hypothesis, and the holistic model of image perception of Kundel et al. (Radiology 242:396–402, 2007). Eye movement and performance data were cumulated from 819 experts, 187 intermediates, and 893 novices. In support of the evaluated theories, experts, when compared with non-experts, had shorter fixation durations, more fixations on task-relevant areas, and fewer fixations on task-redundant areas; experts also had longer saccades and shorter times to first fixate relevant information, owing to superiority in parafoveal processing and selective attention allocation. Eye movements, reaction time, and performance accuracy were moderated by characteristics of visualization (dynamics, realism, dimensionality, modality, and text annotation), task (complexity, time-on-task, and task control), and domain (sports, medicine, transportation, other). These findings are discussed in terms of their implications for theories of visual expertise in professional domains and their significance for the design of learning environments.  相似文献   

Facilitating Understanding of Movements in Dynamic Visualizations: an Embodied Perspective     

Bj?rn B. de Koning  Huib K. Tabbers 《Educational Psychology Review》2011,23(4):501-521

Learners studying mechanical or technical processes via dynamic visualizations often fail to build an accurate mental representation of the system’s movements. Based on embodied theories of cognition assuming that action, perception, and cognition are closely intertwined, this paper proposes that the learning effectiveness of dynamic visualizations could be enhanced by grounding the movements of the presentation in people’s own bodily experiences during learning. We discuss recent research on embodied cognition and provide specific strategies for how the body can be used to ground movements during the learning process: (1) making or observing gestures, (2) manipulating and interacting with objects, (3) using body metaphors, and (4) using eye movements as retrieval cues. Implications for the design of dynamic visualizations as well as directions for future research are presented.  相似文献   

Going Outside in Winter: A Qualitative Study of Preschool Dressing Routines     

Beth?Hatcher  Betsy?SquibbEmail author 《Early Childhood Education Journal》2011,38(5):339-347

The exploratory study focused on describing typical routines of preparing for winter outdoor play with preschool children and their teachers. Naturalistic observations, interviews and photographs resulted in extensive examples of children’s development in cognitive understanding of winter and winter-related concepts. Observations of teachers and assistants revealed task-oriented perspectives including detailed strategies and planning. Asynchronous communication and directive language were typical of teacher/child communication. Photo analyses confirmed physical skills used by preschoolers to accomplish dressing tasks and extensive curricular changes to indoor environments.  相似文献   

Children’s Perspectives on Their Everyday Lives in Child Care in Two Cultures: Denmark and the United States     

Grethe Kragh-Müller  Rebecca Isbell 《Early Childhood Education Journal》2011,39(1):17-27

The purpose of this study was to investigate young children’s perspectives related to their experiences in child care. Researchers used individual interviews and drawings in an early childhood program in Denmark and one in the United States as the basis for examining children’s perspectives on their everyday lives in child care. Observations documented the everyday cultural practices for the children in the two child care centers and provided a foundation for interpreting the interviews and the drawings. The information collected was analyzed to determine what aspects of child care young children like best and least, as well as their thoughts on the adults and peers in their center.  相似文献   

Effectiveness of Case-Based Learning Instruction on Epistemological Beliefs and Attitudes Toward Chemistry     

Aylin ?am  ?mer Geban 《Journal of Science Education and Technology》2011,20(1):26-32

The purpose of the study was to investigate the effectiveness of case-based learning instruction over traditionally designed chemistry instruction on eleventh grade students’ epistemological beliefs and their attitudes toward chemistry as a school subject. The subjects of this study consisted of 63 eleventh grade students from two intact classes of an urban high school instructed with same teacher. Each teaching method was randomly assigned to one class. The experimental group received case-based learning and the control group received traditional instruction. At the experimental group, life cases were presented with small group format; at the control group, lecturing and discussion was carried out. The results showed that there was a significant difference between the experimental and control group with respect to their epistemological beliefs and attitudes toward chemistry as a school subject in favor of case-based learning method group. Thus, case base learning is helpful for development of students’ epistemological beliefs and attitudes toward chemistry.  相似文献

How young people respond to learning spaces outside school: A sociocultural perspective     

Alan?PeacockEmail author  Nick?Pratt 《Learning Environments Research》2011,14(1):11-24

This article focuses on educational enterprises outside the formal sector, such as museums, botanical gardens and interactive science centres. International research is drawn on to illuminate how design, culture, educational strategies and settings combine to affect the way in which young people respond to experiences on offer, leading to analysis of the impact of such settings in promoting learning, and the likely implications for those who staff such venues. Aikenhead’s concept of the educator as ‘culture broker’ is developed to suggest ways in which learning might be best supported. It envisages a shift from ‘delivery’ strategies targeted at large groups towards approaches which focus on what learners choose to know about using dialogue between children and ‘known and trusted people’. Analysis of observed responses in various settings is undertaken from a sociocultural perspective using the notion of communities of practice. Implications for the roles of education managers and their staff in further research are developed.  相似文献

Spannungsfeld Polyvalenz in der Lehrerbildung

The Bologna Process of higher education reform has led to a vast array of different programs of study in German teacher training. In this article, we firstly analyze the implementation of Bachelor programs in teacher training, comparing profession-oriented programs (i.e. those aiming to train students for the teaching profession from the beginning of studies) to polyvalent programs (i.e. those aiming at broad qualifications and including a late decision to become a teacher). Secondly, we investigate whether students enrolled in these study programs differ systematically in their subjective certainty about their career choice. To answer these questions, we analyze portfolios of documents related to teacher training programs from nine German universities that prepare students for teaching in the academic track. Additionally, we analyze data from N?=?2585 Bachelor and N?=?928 Master degree students. We found that most programs, even when they espouse polyvalence, require an early decision to become a teacher. Moreover, our data confirm findings from earlier studies indicating that student teachers are highly certain about their career choice from the very beginning, with students in polyvalent programs being slightly less certain than those in profession-oriented programs (d?=?0.32).  相似文献
