Transforming clinical imaging data for virtual reality learning objects

Advances in anatomical informatics, three‐dimensional (3D) modeling, and virtual reality (VR) methods have made computer‐based structural visualization a practical tool for education. In this article, the authors describe streamlined methods for producing VR “learning objects,” standardized interactive software modules for anatomical sciences education, from newer high‐resolution clinical imaging systems data. The key program is OsiriX, a free radiological image processing workstation software capable of directly reformatting and rendering volumetric 3D images. The transformed image arrays are then directly loaded into a commercial VR program to produce a variety of learning objects. Multiple types or “dimensions” of anatomical information can be embedded in these objects to provide different kinds of functions, including interactive atlases, examination questions, and complex, multistructure presentations. The use of clinical imaging data and workstation software speeds up the production of VR simulations, compared with reconstruction‐based modeling from segmented cadaver cross‐sections, while providing useful examples of normal structural variation and pathological anatomy.

Use of interactive sessions and e‐learning in teaching anatomy to first‐year optometry students

Students enrolled in the Optometry program at the University of Manchester are required to take a functional anatomy course during the first year of their studies. Low mean scores in the written examination of this unit for the past two academic years energized staff to rethink the teaching format. Interactive sessions lasting 20 minutes each were introduced during the two hour lecture sessions. In these sessions students reinforced their anatomical knowledge learned in lectures, through playing games such as anatomy bingo and solving anatomical anagrams. In addition, five e‐learning modules were also introduced for students to complete in their own time. A pre‐ and postcourse questionnaire were distributed to obtain student views on their expectations of the course and interactive sessions. Comparisons were made between written examination results from 2008 to 2009 to written examination results from the previous five academic years to see if the interactive sessions and e‐learning modules had any impact on student knowledge. In addition, comparisons were made between student performances on the functional anatomy course with their performance in all of the other assessments taken by the students during their first year of study. Analysis of the questionnaires showed that student's expectations of the course were fulfilled and the interactive sessions were well received by the majority. There was a significant increase (P ≤ 0.01) in the mean examination score in 2008–2009 after introduction of the interactive sessions and e‐learning modules compared with scores in previous years. The introduction of interactive sessions has increased student enjoyment of the module and along with the e‐learning modules have had a positive impact on student examination results.

Making in‐class skills training more effective: The scope for interactive videos to complement the delivery of practical pedestrian training

Skills and awareness of young pedestrians can be improved with on‐street practical pedestrian training, often delivered in schools in the UK by local authorities with the intention of improving road safety. This training is often supplemented by in‐class paper‐based worksheet activities that are seen to be less effective than practical training in that they focus on knowledge acquisition rather than directly improving the correct application of safe pedestrian skills at the roadside. Previous research indicates that interactive video tools have the potential to develop procedural skills while offering an engaging road safety educational experience, which could positively impact on road crossing behaviour. In this paper, the design and development of a hazard‐identification interactive road safety training video targeting child road crossing skills is presented. The interactive video was shown to be an engaging training resource for 6‐ to 7‐year‐old children. The tool's scope for improving pedestrians' roadside skills is considered along with the wider implications for interactive video to aid safety training in other areas.     

E‐coaching systems: Convenient,anytime, anywhere,and nonhuman

Technologies continue to evolve to provide more compelling and interactive learning opportunities. Coaching has traditionally been face‐to‐face or by email. By combining the new technologies with coaching, learning developers now have the opportunity to develop an asynchronous, online, nonhuman coaching system, or e‐coaching system. An e‐coaching system can alleviate much of the coaching labor while making it more conducive to the coachee.     

Networked interactive video for group training*

The National Computing Centre (NCC) has developed an interactive video training system for the Scottish Police College to help train police supervisory officers in crowd control at major spectator events, such as football matches. This approach involves technology‐enhanced training in a group‐learning environment, and may have significant impact on management training methods.     

Interactive whiteboards and talking books: a new approach to teaching children to write?

This article presents work undertaken with a class of Scottish Primary Six children (aged 10) to investigate the use of interactive whiteboard technology and interactive talking books in whole‐class writing lessons. The paper reports on a research project with three aims: to investigate how the use of an interactive whiteboard to reflect on the language and style of professional authors influenced the children's own writing; to examine the effect of this experience on the writing and behaviour of children with additional support needs; and to identify the advantages and disadvantages of using such technology in whole‐class writing lessons. The resulting evidence suggests that while some children benefited from the approach, teaching children to write through examination of professional models of writing in whole‐class lessons did not promote the most effective learning even where the text was provided in such an interactive medium. The implications of these results for practitioners who wish to use talking books and whiteboard technology to teach writing are discussed.     

Effects of instructional strategies using cross sections on the recognition of anatomical structures in correlated CT and MR images

This research is an effort to best utilize the interactive anatomical images for instructional purposes based on cognitive load theory. Three studies explored the differential effects of three computer‐based instructional strategies that use anatomical cross‐sections to enhance the interpretation of radiological images. These strategies include: (1) cross‐sectional images of the head that can be superimposed on radiological images, (2) transparent highlighting of anatomical structures in radiological images, and (3) cross‐sectional images of the head with radiological images presented side‐by‐side. Data collected included: (1) time spent on instruction and on solving test questions, (2) mental effort during instruction and test, and (3) students' performance to identify anatomical structures in radiological images. Participants were 28 freshmen medical students (15 males and 13 females) and 208 biology students (190 females and 18 males). All studies used posttest‐only control group design, and the collected data were analyzed by either t test or ANOVA. In self‐directed computer‐based environments, the strategies that used cross sections to improve students' ability to recognize anatomic structures in radiological images showed no significant positive effects. However, when increasing the complexity of the instructional materials, cross‐sectional images imposed a higher cognitive load, as indicated by higher investment of mental effort. There is not enough evidence to claim that the simultaneous combination of cross sections and radiological images has no effect on the identification of anatomical structures in radiological images for novices. Further research that control for students' learning and cognitive style is needed to reach an informative conclusion. Anat Sci Ed 1:75–83, 2008. © 2008 American Association of Anatomists.     

Perspectives in Science — Exploring Science,Technology and Society

Abstract

The National Film Board of Canada is breaking new ground in educational technology with a pilot series of ‘interactive’ videos entitled Perspectives in Science. The series, aimed at the junior high school level, addresses issues of environmental and sociological concern not traditionally dealt with in formal science curricula. This paper examines the rationale behind the development of the Perspectives in Science video series. Science curriculum guidelines across Canada are being re‐written to reflect a change in education strategies that will encompass not only the teaching of scientific concepts, but also the applications of those concepts, as well as the implications of utilizing those concepts. Referred to as the ‘S‐T‐S’ connection, or, Science‐Technology‐Society, the new focus has been extensively documented by the Science Council of Canada and is currently causing a stir in the science teaching community as teachers scramble to find audio‐visual productions that address these new concerns and, at the same time, engage their students.

This paper also explains the design concept for presenting materials on S‐T‐S in an interactive model. Each video includes a short, open‐ended drama, followed by a number of ‘interactive components’. The tapes are ‘interactive’ in that teachers and students can choose to follow the material linearly or search for specific segments using the running time code as an electronic page reference. The interactive components consist of documentary style discussions with Canadians involved in some aspect of the scientific, technological, and societal issues presented, animated sequences, experiments, and filmography. The videos investigate issues of water, biotechnology, and toxic waste—with additional topics on soil, forestry, and air in production.

Finally, this paper documents the formative evaluation of the series noting the favourable response of teachers and students to the design concept and material content. The findings of this research indicated that the interactive video was both timely and appropriate for science teaching in view of major changes now being made to science curricula.

Supporting students to develop collaborative learning skills in technology-based environments

The paper focuses on the question of how to advance collaboration through the Web and support lifelong learning. First, the theoretical framework and architecture of a new web‐based tool, the ‘IQ Team’, is introduced. IQ Team is an interactive online assessment and support system to learn social skills needed in cooperative work, and belongs in an interactive online assessing and tutoring system, ‘IQ Form’, developed for the Finnish Virtual University. IQ Team has three main elements: (1) interactive self‐evaluation test banks, (2) online tutoring sets and (3) learning diaries. In the creation of IQ Team, the validation process was conducted with two samples (n = 259 and n = 275). The online students’ social skills in different groups were explored, and the feedback data from different user groups were analysed. The online students scored high values for social skills, and no differences were discerned between university, Open University and technical students. The qualitative data (n = 35) were collected in order to get users’ feedback of the tool. The qualitative data consisted of interviews, open‐ended questions and online discussions. The users of IQ Team reflected that the tool benefited them to become aware of their group work skills and developed their collaborative learning skills. IQ Team provides a powerful tool for online instruction and communication in higher education and in the Open University to promote joint‐regulated learning.     

Examining the characteristics of student postings that are liked and linked in a CSCL environment

This case study is the first iteration of a large‐scale design‐based research project to improve Pepper, an interactive discussion‐based learning environment. In this phase, we designed and implemented two social features to scaffold positive learner interactivity behaviors: a “Like” button and linking tool. A mixed‐methods approach was used to examine communicative and cognitive characteristics of notes. Additionally, we develop and apply a new metric for cognitive complexity that acknowledges a range of cognitive behavior valuable to a learning community. The findings suggest that the Like and linking functions positively cultivated and sustained interactive behaviors among students, which also led to an increase in the cognitive complexity of student contributions to the online discussion. Suggestions for future iterations of this project are offered.     

Professions in organizations,professional work in education

Professions are occupational arrangements for dealing with human problems. Professional ‘people work’ requires a certain interactive closeness; face‐to‐face communication is prominent in professional–client relations. This also seems the case in the educational system. But in education, organization provides the raison d’être of this profession. This organizational infrastructure enables and delimits educational interaction. The school bureaucracy is criticized by the profession; the profession has an outspoken interest in reforming its organizational infrastructure again, again and again. This article provides a theoretical analysis of teaching, which elucidates this relation between profession, organization and work.     

Instructional Technology and Distance Learning Through the Internet

Abstracts

English: The article maps the possibilities open to teaching institutions in distance learning through the Internet. It considers the ways in which the Internet allows us to evaluate the efforts and strategies that should be chosen in order to implement distance learning through the Internet according to the organization's teaching goals and the type of distance teaching it chooses. The basic terms of synchronic and asynchronic learning, non‐interactive learning, scope and learning‐time circles are defined and they create a system of axes upon which one can place distance learning in an organization or a course that consists of various aspects of distance learning.     

An Analysis of an Interactive Videodisc System for Teaching Language Skills to Deaf Students

An interactive videodisc system designed to teach language concepts to deaf students was evaluated in a classroom trial. An experimental group of 18 students spent 60 twenty‐minute sessions over a five‐month period learning language concepts by interacting with the system while a control group of 16 students learned the same concepts in their regular classroom setting. Both groups made significant progress from pre‐ to post‐test on two criterion‐referenced testsdeveloped by project staff. Experimental students were enthusiastic about the videodisc, felt that their language skills had improved, and were anxious to continue working with the system.

互联网的飞速发展使网络学习成为人们越来越普遍的学习方式，已有的研究和实践均表明，交互是影响网络学习效果的重要因素。当前，网络交互形式主要集中在文本交互上，因此，分析交互文本也就成了探讨网络学习中交互效果的重要视角。本论文从网络学习社区的特征入手，设计了一套从认知存在、社会存在和教学存在三方面来分析讨论区中交互文本的编码体系，然后利用这套编码体系，对两门混合式学习课程的交互文本进行了内容分析，并提出了指导意见。经过初步证实，这套编码体系能够比较全面地解释在线课程讨论区中的交互效果以及存在的问题，而且编码体系简约、过程简易，且具有可操作性。     

Monitoring online communication: can the development of convergence and social presence indicate an interactive learning environment?

More units of study are being offered flexibly, using distance education and online facilities, as a consequence of recent educational developments in higher education, with learner expectations of being able to study when they like and where they like, as well as increasing class enrolments and more students studying remotely or part‐time. However, the quality of the learning experience and the efficacy of placing learning activities that require student interaction and discourse in an online environment have been questioned. The concerns raised by educators regarding placing learning activities online are often about the types of learning environments that are being created and the tools available to support student communication in a virtual learning environment. Asynchronous computer‐mediated communication is one means of allowing students to communicate independently of time and place, and to communicate questions, opinions and queries when transferring interactive learning activities to an online environment. The use of threaded, online discussions that allow asynchronous communication has been criticised for not producing the perceived benefits for learners and educators. This paper assesses the use of asynchronous computer‐mediated communication and the degree of convergence and level of social presence as indicators of developing highly responsive and interactive learning environments in the context of an inquiry‐based learning activity, using a case study approach with problem solving and self‐directed research.     

Using the multimodal affordances of the interactive whiteboard to support students’ understanding of texts

The purpose of the study reported on here was to explore ways in which the interactive whiteboard (IWB) can support students’ understanding of texts. A Year 3 and a Year 4 primary school class in New South Wales, Australia, is the focus of the research. A qualitative case study was carried out using multimodal analysis focusing on the use of an e‐book displayed via the IWB. The results of the study indicate that the IWB can support students’ understanding of a narrative to prepare them to write a whole‐class response through providing increased access to a range of resources that are multimodal in nature. The way the interactive features of the IWB can facilitate access to multimodal resources to cater for student needs is also discussed.     

UNDERSTANDING TEST‐TYPE ASSIGNMENT: WHY DO SPECIAL EDUCATORS MAKE UNEXPECTED TEST‐TYPE ASSIGNMENTS?

We interviewed special educators (a) whose students with disabilities (SWDs) were proficient on the 2008 general education assessment but were assigned to the 2009 alternate assessment based on modified achievement standards (AA‐MAS), and (b) whose students with mild disabilities took the 2008 alternate assessment based on alternate achievement standards (AA‐AAS) and then the 2009 AA‐MAS. We explored teachers’ rationales for test‐type assignment, student characteristics, and quality of instruction to determine the test‐type decisions’ appropriateness. All teachers based their decisions on combinations of factors in the guidelines plus subjective and noninstructional factors. Findings raised concerns about the subjectivity of the assessment assignment system and the inappropriate grade‐level instruction for SWDs. Future research, implications of these findings, and limitations are discussed.     

Technological novelty and open‐endedness: Two characteristics of interactive exhibits that contribute to the holding of visitor attention in a science museum

This study was undertaken to isolate characteristics of interactive exhibits that are particularly effective in attracting and holding the attention of visitors in a science museum. Forty‐seven visitors were tracked through two adjacent exhibitions, comprising a total of 61 interactive exhibits. Four exhibit characteristics were identified and examined: technological novelty, user‐centeredness, sensory stimulation, and open‐endedness. Regression analyses show that two of these characteristics, technological novelty and open‐endedness, help to account for the variance in average visitor holding time; these characteristics have positive correlations with the amount of time spent by visitors at exhibits. Nonsignificant results are explained in terms of mitigating environmental and exhibit‐related factors. In addition, topics for future study are suggested. © 2003 Wiley Periodicals, Inc.
