Abstract: The purpose of this study was to investigate the effects of two different methods on primary school teacher candidates’ academic achievements and attitudes toward computer-based education, and to define their views on these methods. Both the first experimental group, programmed instruction (PI), and the second experimental group, meaningful learning (ML), included 36 students separately. While a significant difference was found between the groups regarding academic achievements, no significant difference was found between the groups’ attitude scores. There was no significant difference between the academic achievements of the students according to their genders in both groups. In addition, while there was no significant difference between the pre-test and post-test attitudes of students in the PI group, a significant difference was determined in the ML group. Generally, in the PI group, students considered the method effective but boring. Besides, students in the ML group had positive views on the method. [Copyright &y& Elsevier]

Abstract: This study reports on the development of ESP (English for Specific Purposes) multimedia courseware on oral presentations, and its integration into self-study learning and elective courses for students with different English proficiencies, as one solution to problems in ESP courses in Taiwan. The courseware design is based on Mayer’s multimedia learning cognitive theory, and the language learning focus draws on Chapelle’s suggested criteria for development of multimedia CALL. Evaluation of student performance with two different formats for courseware integration is based upon data from pre- and post-tests for preparing speech texts, and a questionnaire survey. The courseware provides authentic materials with a logical situational layout and a friendly interface design for learning ESP for oral presentations in international business and technical settings and offers rich and flexible learning activities with corresponding on-line self-evaluation so that students actively engage in cognitive processing. Students with different English proficiencies have different concerns about giving a presentation. Meanwhile, after students’ self-study for six weeks, regardless of level of proficiency, students’ learning effectiveness and satisfaction with the courseware integration were significantly improved, by qualitative and quantitative analysis. Such students’ improvement suggests success of the courseware design and learning effectiveness with its integration. [Copyright &y& Elsevier]

A novel instructional computer simulation that incorporates a dynamic analogy to represent Le Chatelier’s Principle was designed to investigate the contribution of this feature to students’ understanding. Two groups of 12th grade Chemistry students (n =15) interacted with the computer simulation during the study. Both groups did the same pre-instructional and simulation activities except one of the groups interacted with the analogical example in the simulation and the other group was asked to recall an analogy that was presented in the form of text and pictures. A statistical analysis of the tests administered at the end of the study suggested that analogies that are dynamic, interactive, and integrated in a computer simulation may have a stronger effect on learning outcomes than analogies which are presented in the form of text and static pictures. The implication of this study for science educators is that dynamic computer-based analogies can enhance student learning of unobservable phenomena in science. [Copyright &y& Elsevier]

Computer-based learning (CBL) is well established and its benefits are widely reported. It has found considerable utility in recent years with the explosion in interest in the use of the Web as a knowledge medium. Many online courses, however, consist merely of a series of textual notes and pictures with little navigational information or choice. In previous studies we have suggested that there are a number of usability and interactivity mistakes that are commonly made when preparing online learning material. These can be used to develop a set of principles for good design. Here, we apply those principles to modules in genetics and reproduction. This allows us to test the hypothesis that material presented in an interactive, easily navigable computer-based learning system (a “Virtual Lecture” or VL) creates a significant improvement in the student learning experience over identical material presented as simply pictures and text in scrollable Web pages (“Web pages”). The student learning experience was measured in terms of performance in summative assessment and through questionnaire analysis. Two separate studies were conducted. The first study involved two cohorts of students with one being given material as Web pages and another (a year later) given it in the form of a VL. The results showed a significant increase in final examination marks for students taking material as a VL compared with Web pages. Students using Web pages also expressed some discontent with their experience but those using the VL did not. In the second study we divided a single cohort into two groups and exposed them to material in the form of both Web pages and a VL. The results of a multiple-choice assessment reveal a significant increase in scores for material presented as a VL. Questionnaire analysis also revealed overwhelming preference for the VL approach. Taken together, these studies provide compelling evidence that a carefully designed interface can provide a significant improvement in the student learning experience compared to presenting material as scrollable Web pages consisting simply of pictures and text.

An advanced learning system for interactive simulation of patient cases (ISP) is described. The system was designed to meet specific pedagogical needs where student activation and problem orientation were two of the key issues. The system includes features such as video based illness history-taking function using free text input, highly interactive physiological examination procedures, extensive laboratory tests and detailed user feedback. The system was constructed mainly in Authorware Professional, starting more than 10 years ago, and it is now available in refined versions in different languages. Twelve pedagogical and three technical features were initially defined for the project. All of these aims were fulfilled. The ISP system has been successfully used in education, and in international collaboration, including three applicability field tests. The system is also a powerful research tool for studying for instance medical decision-making. [Copyright &y& Elsevier]

This paper presents Bigger Bits, an interactive multimedia learning environment that teaches students about VLSI within the context of computer electronics. The system was built with COSMOS (Content Oriented semantic Modelling Overlay Scheme), which is a modelling scheme that we developed for enabling the semantic content of multimedia to be used within interactive systems.

This article presents the design and preparation using hypermedia tools of an interactive CD-ROM for the active teaching and learning of diverse problem-solving strategies in Mathematics for secondary school students. The use of the CD-ROM allows the students to learn, interactively, the heuristic style of solving problems. A range of problems has been used, each of which requires different solving strategies. A complementary section for consulting the theoretical foundations for the process of solving problems and other related information is also included on the CD-ROM. This section provides both theoretical and curriculum support for teachers. [Copyright &y& Elsevier]
