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.

Authentic Assessment and Multimedia: how university students respond to a model of authentic assessment

A problem for educators and the developers of interactive multimedia is the apparent incongruity between the demands of authentic assessment and the deliverables of computer‐based assessment. Lecturers wishing to use interactive multimedia are commonly limited to assessment using multiple choice tests which are easily marked by the computer.

This article describes seven defining characteristics of authentic assessment which have been operationalized in a learning environment employing interactive multimedia. The article describes the multimedia program and its implementation with a class of pre‐service teachers. The implication of these findings for educational practice are that authentic assessment can be used within interactive multimedia learning environments, albeit not totally contained within the software itself. The qualitative study reported here showed that students responded favourably to the elements of authentic assessment; that they had a good understanding of the content of the interactive multimedia program; and that the assessment was corroborated by observation of teaching strategies used by the students in their teaching practice.     

A second-grade teacher's adaptive teaching during an integrated science-literacy unit

This case study explored the nature of one elementary school teacher's adaptive teaching during an integrated science and literacy unit. Data were collected during four consecutive weeks of instruction, weekly interactive planning sessions, 20 classroom observations, and 20 post-lesson interviews. Our analysis suggests that adaptations may be established during planning or emerge while teaching. This study also indicated that an adaptive teacher uses ongoing formative assessment to scaffold students' learning. A coding system that typifies how and why a teacher adapts instruction across disciplines can be used to examine adaptive teaching. Implications for teacher educators and researchers are discussed.     

Students as ‘Producers’: using videodisc technology to create stories

The use of videodisc technology to teach a variety of subject matter across many disciplines is an area of interest to many educators. This paper discusses an interactive videodisc program that was implemented in a classroom setting with fifth and sixth grade children. The program, called Producer, was introduced to children and then used as part of a six‐week summer enrichment classroom. A discussion of how children interacted with the Producer program to create stories is discussed based on videotapes of the teaching sessions. The implications of using videodisc technology to teach children are reviewed.

Teaching about Human Relationships Education for primary school student‐teachers using an interactive CD‐ROM

Human Relationships Education is a very important part of primary school student‐teacher education. All primary school children need sound guidance and enhanced knowledge about puberty, growing up successfully, and feeling competent and confident in themselves. An interactive multimedia CD‐ROM was designed and developed for some Australian university student‐teachers in the final fourth year of their Bachelor of Education (Primary School), and addresses the Human Relationships Education curriculum. This paper analyses some of the pedagogies used in this pastoral care learning as examples of a Constructivist approach to designing multimedia interactivities based on Anderson and Krathwohl's learning framework. Such an approach may be useful for other educational designers to improve student‐teacher involvement in their pastoral care learning, to provide pedagogical variation and to use interactive multimedia, thus enhancing learning outcomes for student‐teachers and, in turn, their primary school students.

Maintaining Research Documents with Database Management Software

Summary

This article reviews the development and delivery of a Higher Education course module as part of a large European University's Integrated Masters Program operating through a regional network of Rural Area Training and Information Opportunities (RATIO) telematic centres. The aim of the project was to provide remote learners living in the southwest of England with computer-supported solutions to access higher education as part of a technology-assisted distance education program. The module represented a shift from traditional educational delivery systems by using instructional courseware via an Internet Web site. Personal communications with module participants were conducted with the use of e-mail and videoconferencing information technology (IT) resources. Out of the original sixteen participants who enrolled in this Masters course module, four actually completed the learning sessions and two submitted final assignments. This article considers the key lessons learned from this attrition rate and shares the mainly positive experiences of the remote tutor and the students engaged in this initiative. The implications regarding the use of the Internet for delivering higher education course modules through online distance learning are discussed in the light of cautions learned from this research project and important practical recommendations for future practice are made.

A Teacher Professional Development Program on Using a Constructivist Multimedia Learning Environment

This paper describes a professional development program using an interactive multimedia program to develop teachers' understanding of a constructivist epistemology in science education. The aim of this study was to describe teachers' reflections on and perceptions of a series of professional development workshops and how teachers changed their classroom practices after having participated in the workshops. The software, developed with the cooperation of teachers and students, is based on the Birds of Antarctica database (Maor & Phillips, 1996). This database was designed as an interactive program which requires teachers to use a constructivist-oriented approach to teaching and learning in order to promote the development of inquiry skills particularly higher-order thinking skills. A series of workshops for teachers was conducted to empower them to become comfortable with using computers in science classrooms and to enable them to enhance their understanding of, and ability to use, personal and social constructivist approaches. Teachers' perceptions of the process of learning with the multimedia program and their reactions to their experiences were assessed using a new instrument, the Constructivist Multimedia Learning Environment Survey (CMLES). The results of the study suggest that teachers who participated as learners in the professional development program became familiar with a constructivist-oriented multimedia learning environment; understood the context, problems, and issues faced by students in the classroom; and were better able to facilitate students' needs and understanding in this learning environment. This revised version was published online in July 2006 with corrections to the Cover Date.     

Multimedia Resources to Bridge the Praxis Gap: Modeling Practice in Elementary Science Education

Numerous research studies have shown that science methods courses based on constructivist approaches can enhance teacher knowledge and confidence in ways that foster more positive attitudes to the teaching of science. However, a critical part of reflective practice is the opportunity to observe competent professionals practising their craft. Opportunities to observe teachers engaging in constructivist and inquiry based practices in many undergraduate programs are limited. Our goal was to make visible the pedagogical practices and assumptions of teachers through a suite of multimedia resources that provided visual examples of professional practices. In this paper, we report on the development and use of these multimedia resources. These resources incorporated interactive CDROMs, videos and websites and supplemented an instructional program that engaged learners in a range of reflective practices. Evaluation data were derived from focus group interviews with preservice teachers, from interviews with instructors and from surveys with inservice teachers. Analysis of these data supports the value of multimedia material as a vicarious learning experience; and highlights the extent that multimedia can demystify science teaching.

Comparison of traditional methods with 3D computer models in the instruction of hepatobiliary anatomy

This study was designed to determine whether an interactive three-dimensional presentation depicting liver and biliary anatomy is more effective for teaching medical students than a traditional textbook format presentation of the same material. Forty-six medical students volunteered for participation in this study. Baseline demographic information, spatial ability, and knowledge of relevant anatomy were measured. Participants were randomized into two groups and presented with a computer-based interactive learning module comprised of animations and still images to highlight various anatomical structures (3D group), or a computer-based text document containing the same images and text without animation or interactive features (2D group). Following each teaching module, students completed a satisfaction survey and nine-item anatomic knowledge post-test. The 3D group scored higher on the post-test than the 2D group, with a mean score of 74% and 64%, respectively; however, when baseline differences in pretest scores were accounted for, this difference was not statistically significant (P = 0.33). Spatial ability did not statistically significantly correlate with post-test scores for the 3D group or the 2D group. In the post-test satisfaction survey the 3D group expressed a statistically significantly higher overall satisfaction rating compared to students in the 2D control group (4.5 versus 3.7 out of 5, P = 0.02). While the interactive 3D multimedia module received higher satisfaction ratings from students, it neither enhanced nor inhibited learning of complex hepatobiliary anatomy compared to an informationally equivalent traditional textbook style approach. .
