Dimensions of educational transactions in a videoconferencing learning environment

Abstract

Moore's Theory of Transactional Distance suggests that dialogue, structure, and learner autonomy are the key elements delineating the educational transaction in distance learning environments. However, the conceptualizations of these concepts in a telecommunication era have not been systematically addressed. By investigating 121 learners’ experiences with videoconferencing, this study identified the dimensions (factors) constituting dialogue, structure, and learner autonomy in such a learning environment. Exploratory factor analysis using a principal axis factor method was carried out. It was concluded that each of these three concepts represented multi‐faceted ideas. Dialogue consisted of three dimensions: in‐class discussion, out‐of‐class electronic communication, and out‐of‐class face‐to‐face interaction. Structure contained the dimensions of course organization and course delivery. Learner autonomy was comprised of independence and interdependence. The results of this study can inform videoconferencing researchers and practitioners of the factors of the educational transaction that should be considered in videoconferencing courses.     

The quality of teaching and learning via videoconferencing

Now that videoconferencing is being widely used for the delivery of mass lectures between sites, there is concern that the quality of teaching and learning experienced, using this method of delivery, is not as good as that experienced in a traditional classroom situation. The study aimed to investigate this concern by using a research diary to collect information on classroom activities and cognitive outcomes which students at local and remote sites experienced over a ten–week period. The results indicated that remote site students did not experience the same quality of teaching and learning as local site students.     

Where knowledge construction,equity, and context intersect: Student learning of science in small groups

To provide insight into the strengths and limitations of using groupwork to promote excellence and equity in science education, the researcher investigated how students using the Complex Instruction model of groupwork constructed scientific knowledge. Eighty sixth-grade students and one life science teacher at an urban middle school participated in this study. Qualitative analysis of videotapes and interviews makes clear that group discussions rarely moved beyond observational or procedural matters, that students of high status (perceived academic ability and popularity) had greater access to their groups' materials and discourse, and that students made few connections among the contexts of school, science, and everyday life. Quantitative analyses of participation during groupwork and performance on unit tests show that high-status students had significantly higher rates of on-task talk than their middle- or low-status counterparts, and that those students who talked more learned more as well. Thus, although groupwork should not be summarily dismissed as an instructional strategy, group tasks and implementation must be further refined to adequately address the dual goals of excellence and equity: Students need greater guidance in how to talk and do science, and teachers, greater assistance in eliminating differences in student participation and achievement. © 1997 John Wiley & Sons, Inc.

Pushing the boundaries of interaction in videoconferencing: A dialogical approach

Building on experiences with a group of Masters students in 1994, videoconferencing was used the following year to enhance delivery to distance education students in Hong Kong. Following six weeks intensive study on‐campus in Brisbane, students returned to their base in Hong Kong and were connected to their fellow students in Brisbane via videoconference. Employing a dialogical approach, the lecturers used these sessions to push the boundaries of videoconferencing for interactive higher order discussions.     

Seeing is believing: the role of videoconferencing in distance learning

The potential of videoconferencing to enrich distance learning needs to be widely recognised as well as the technology embedded in curriculum delivery and in distance learning programmes. The argument is supported by reference to a wide range of case studies from the author's experiences over a period of six years as International Officer with the Western Education and Library Board in Northern Ireland, and to exemplars of good practice from other sources in different parts of the world. As videoconferencing becomes more widely available in schools and in public libraries, it is important that there is a new awareness of its vast potential in order to ensure that this technology is fully exploited for the benefit of learning communities.     

Teaching and learning by videoconferencing at the University of Ulster

The Open University has developed an array of tutorial and advisory services for its students over 16 years. These have been reviewed regularly for their academic appropriateness and effectiveness. More recently, urgent reductions in services have taken place, in response to financial restraints. During 1985, Mary Thorpe and colleagues in the Student Research Centre, the Institute of Educational Technology conducted in‐depth interviews with students and staff to explore their perceptions of studying with the Open University.     

The interaction of student characteristics and science teaching on student perception of the learning environment

Conclusion The interactive perspective adopted in this study suggested an alternative approach to the study of the effects of student characteristics upon their perceptions of the classroom. This perspective emphasised the necessity to examine the nature of the interaction between the student (or more exactly the student variable) and his learning environment before testing for the presence of these effects. Six relationships were consequently proposed, and both the analyses and qualitative data supported the presence of five of these in the ongoing activities of the classroom. This paper forms part of a larger study done by the author while a member of the Education Research Unit, Research School of Social Sciences, Australian National University.     

Effects of role division, interaction, and shared mental model on team performance in project-based learning environment

The purpose of this study was to investigate the cognitive mechanism of project-based learning teams of college students on the basis of the Shared Mental Model (SMM) theory. The study participants were 237 female college students in Korea organized into 51 project teams. To test the study hypotheses, a structural equation modeling was employed. The major study findings are as follows: (1) As hypothesized, member interaction was a strong predictor both for team-related and for task-related SMM. (2) The level of the team’s division of labor reduced the member interactions. (3) Team-related and task-related SMMs were positively associated with team performance. The theoretical and practical implications based on these results are discussed.     

Changes of interaction during the development of a mathematical learning environment

Two research questions are answered: how did teacher instructional skills develop during a whole school year? What is the influence of this development on the interactions between students during the co-operative learning moments? From the analysis, it appeared that the teachers’ instruction changed from direct instruction to a more process and group-oriented coaching style, and that students started to work collaboratively, using the graphic calculator in an exploratory and investigative manner. This more process and group-oriented coaching style may have supported the change in the interaction pattern during this school year. The analysis showed that students gradually developed a more exploratory way of collaborating, confirming improved collaborative learning. At the commencement of the school year, students were focused on each other and did not argue much, while at the end, they were discussing with one another.     

Building bridges to student learning: Perceptions of the learning environment,engagement, and learning outcomes among Chinese undergraduates

The study examined the relationships among students’ perceptions of the learning environment, prior academic achievement, engagement, and learning outcomes (cumulative university GPA, generic skills development, and learning satisfaction) with a sample of 2,616 seniors from a full-time research-oriented university in Mainland China. The results supported a model which showed that students’ perceptions of the learning environment and prior academic achievement had direct effects on learning outcomes, and indirect effects via their engagement. The effects, however, varied depending on the type of the outcome in question: (1) Student engagement mediated the relationship between course experience and generic skills development, (2) cocurricular experience positively predicted learning satisfaction, (3) first semester GPA positively predicted cumulative university GPA, and (4) National College Entrance Examination scores did not correlate with any other factor. A major proportion of the variance in the three types of learning outcomes was accounted for by the model, showing its effectiveness in predicting university students’ learning. Implications for improving undergraduate education in China are provided.     

Inter-Life: a novel,three-dimensional,virtual learning environment for life transition skills learning

This paper presents the findings from one of the first empirical research studies which has investigated the impact of Inter-Life; a novel three-dimensional immersive virtual learning environment, on learning and development of social and educational life transition skills in a group of looked after and accommodated children. Drawing on social constructivism in which meaningful learning is related to context and situated in practice, we report on a series of Inter-Life workshops that enabled young people to work together and through the processes of participation in authentic learning activities contributed to the development of life transition skills such as self-confidence, empathy, negotiation and mediation skills, teamwork and active problem-solving skills. The novel affordances of the Inter-Life virtual world which contributed to the development of the learning community included the ability to personalise learner engagement and activities from the outset along with ‘co-presence’ and ‘immersion’ and the flexibility provided by the innovative, technology-enhanced Inter-Life platform. This study presents some empirical evidence to demonstrate the efficacy of new models of learning that are mediated by innovative malleable technologies that can be shaped by the learner in a participatory manner.     

Web-based learning interaction and learning styles

This paper reports a study exploring the learning styles and perceptions of a group of undergraduate and postgraduate learners in a university in the UK in relation to using the web for learning. In particular, we explore the sequential/global learning style dimension (which is concerned with the progress of understanding) in relation to three categories of web‐based interaction: learner‐tutor, learner‐learner, and learner‐information. An Index of Learning Styles is used as the tool to explore this dimension. The findings are presented with regard to the learning preferences of a group of learners towards these three categories of interaction. We conclude with a discussion of these findings in relation to Interactive Learning Systems (ILSs) design.     

Distance learning and interaction: Toward a virtual learning institution

This paper considers distance learning at all levels, learning that can occur anywhere. Most education today in schools, universities, and companies is dependent on students being at a particular location, such as a university. The major distance learning institutions today are in Europe, but the potential for this type of learning is great as we reach out to serve greater numbers of students. The following factors are critical in forming a distance learning institute today: the quality of learning provided to each student; whether courses work for very large numbers of students; and the cost per student hour, for both development and delivery. Many delivery technologies are possible today. We examine them from the standpoint of these factors. The conclusion is that highly interactive multimedia learning units, either CD ROMs or (in the near future) broadband networks, provide the best delivery system today for distance learning. The paper concludes with a brief review of strategies for developing the curriculum units needed to support distance learning.     

Learning environment,learning styles and conceptual understanding

In recent years there have been many studies on learners developing conceptions of natural phenomena. However, so far there have been few attempts to investigate how the characteristics of the learners and their environment influence such conceptions. This study began with an attempt to use an instrument developed by McCarthy (1981) to describe learners in Malaysian primary schools. This proved inappropriate as Asian primary classrooms do not provide the same kind of environment as US classrooms. It was decided to develop a learning style checklist to suit the local context and which could be used to describe differences between learners which teachers could appreciate and use. The checklist included four dimensions — perceptual, process, self-confidence and motivation. The validated instrument was used to determine the learning style preferences of primary four pupils in Penang, Malaysia. Later, an analysis was made regarding the influence of learning environment and learning styles on conceptual understanding in the topics of food, respiration and excretion. This study was replicated in the Philippines with the purpose of investigating the relationship between learning styles and achievement in science, where the topics of food, respiration and excretion have been taken up. A number of significant relationships were observed in these two studies. Specializations: science education, primary science, educational research and measurement, educational management.     

The interaction of learning environments and student discourse about knowing,learning, and the nature of science: Two longitudinal case studies

This is one of a series of studies conducted by a high school physics teacher, who used constructivist referents to plan and enact the curriculum, and to understand and improve the learning environment in his physics classes. Data were collected in the course of a two-year physics course including (a) repeated administrations of a classroom learning environment survey, (b) written essays on the topics of knowing, learning, and classroom learning environment, and (c) interviews. While there was a general trend for students to adopt more constructivist views of knowing and learning, there was also a small number who resisted to adapt to the constructivist learning environment in their physics course. Two case studies of individual students are used to illustrate the interactions of the learning environment, student understanding of scientific knowledge, and the nature of science, and students' views of their own learning.     

Modelling a learning environment: Towards a learning organization

Abstract

The role of the academic developer mirrors that of the current day academic. It is increasingly diverse and complex. Staff employed in academic development units are expected to respond to the needs of individual academics and are also expected to provide leadership in teaching and learning, conduct research into higher education, contribute to policy on a broad range of issues, and undertake community service. In addition they are expected to take responsibility for their own professional development. They are constantlyjuggling priorities of personal, professional and organizational commitments. To maintain competence in the face of multiple demands there must be significant overlap between work and learning. The learning opportunities inherent in working within a large multi‐dimensional organization must be acknowledged and embraced through the concept of a ‘learning organization’. It is important that the organizational culture of the Academic Development Unit (ADU) values learning, encourages reflection and fosters collaborative practice. This paper outlines an organizational model of academic development highlighting the opportunities for intervention at the level of organizational culture, staff development and student learning. It also suggests strategies for organizing and managing an ADU that provides a positive model of an effective working and learning environment.
