The purpose of this study was to examine the effects of multimedia strategies for instructional techniques and practice on non-native novices' Chinese character learning performance and cognitive load. Two types of multimedia instructional presentations – radical-highlighted and stroke-pronunciation – and two types of practice – visual cue and voice cue – were implemented. Participants were 81 non-native novices randomly assigned to one of the four experimental groups, namely radical-highlighted visual-cue, radical-highlighted voice-cue, stroke-pronunciation visual-cue and stroke-pronunciation voice-cue. An Internet-based e-learning course on the basis of Chinese characters was implemented and delivered as experimental instruction using a Moodle platform. The results show that, for non-native novices, the stroke-pronunciation (SP) strategy of showing strokes with pronunciations is better than the radical-highlighted (RH) strategy, enabling the novices to achieve better performance in identifying Chinese radicals. The significant two-way interactions suggest that (1) the SP presentation should be delivered with the voice-cue (VoC) practice to elicit better performance in writing and in identifying characters and strokes, and (2) the RH presentation should be delivered with visual-cue (ViC) practice to elicit better performance in character writing. Furthermore, participants showed similar levels of perceived cognitive load toward the stroke-based task and the radical-based task. However, when the SP presentation was delivered with the VoC practice, participants revealed lower perceived cognitive load toward the writing task.  相似文献

This study explores a teaching method for improving business students’ skills in e-commerce page evaluation and making Web design majors aware of business content issues through cooperative learning. Two groups of female students at a Japanese university studying either tourism or Web page design were assigned tasks that required cooperation to investigate whether a minimum of formal training and interaction between the two groups would result in an increase in the “design” students’ awareness of content issues in page design, and an improvement in the “tourism” students’ ability to evaluate Web pages related to tourism. The results showed only slight improvements, suggesting that either the amount of cooperative learning must be increased or some formal instruction must be introduced.  相似文献

Developing interactive history learning materials to facilitate historical thinking is one of the challenges in history teaching and learning. This study developed a web-based history educational system, which has used the acronym HES-SPATO (history educational system based on SPATO), to increase the understandability of history learning materials. SPATO (spatial, person, action/attribute, and temporal object) was designed to integrate the indispensable elements of history events such as space, person, action/attribute, and time. HES-SPATO also applied temporal logic to reason the temporal relationships between history events. Furthermore, it employed the GIS concept of information layers to develop the student interface. The findings of the experiments indicated that the use of HES-SPATO was effective in enhancing students’ history learning. The participants also showed positive attitudes toward the HES-SPATO system in terms of the perceived ease of use, perceived usefulness, attitude to use, intention to use, recall of web sites, and perceived usefulness of assistant tools. Although many functionalities have been added to the HES-SPATO system, there was no significant difference in system efficiency between HES-SPATO and the comparative system. These experimental results also guide the direction of future research.  相似文献

In Taiwan, promoting knowledge of “Labor Safety” which relates to life and work right is very important. Safety training and learning effectiveness become essential issues of adult learning. To reduce the costs of educational training, enterprises have also started to aggressively introduce e-learning education training. Unlike the construction industry, few studies have investigated the effectiveness of e-learning and conventional learning. This study tested the effectiveness of the safety education to prevent falls by different learning modes used to assess safety behavior and learning effectiveness during the education training period. According to the average pass rate, satisfaction degree of course and total number of unsafe behavior, the e-learning mode improves learning effectiveness. Additionally, when the e-learning mode is introduced in the construction safety education training, the labor can use the teaching material more independently and multimedia system, such as animated teaching materials, case teaching, and repeated course learning, to reduce the error rate of operation, property loss rate, and light (heavy) injury. Under this condition, the e-learning mode is positively associated with the learning effectiveness of construction safety education training. High learning effectiveness promotes safe behavior during construction operations.  相似文献

The purpose of the study is to investigate the potential benefits of using animation, visual cueing, and their combination in a multimedia environment designed to support learners’ acquisition and retention of scientific concepts and processes. Undergraduate participants (N = 119) were randomly assigned to one of the four experimental conditions in a 2 × 2 factorial design with visual presentation format (animated vs. static graphics) and visual cueing (visual cues vs. no cues) as factors. Participants provided with animations retained significantly more concepts than their peers provided with static graphics and those afforded visual cues learned equally well but in significantly less time than their counterparts in uncued conditions. Moreover, taking into consideration both learning outcomes and learning time, cued participants displayed more instructional efficiency than their uncued peers. Implications and future directions are discussed.  相似文献

The design of educational software interfaces is a complex task, given its high domain dependency and multidisciplinary nature. It requires that teachers’ knowledge and pedagogical beliefs be incorporated into the interface, posing a challenge to both teachers and designers, as they have to act as partners from the earliest phases of the process, sharing their knowledge. The present work investigates the strategies designers used when paired with experienced teachers, to design two interfaces on chemistry, evaluating how designers work with subjects they know little about, in the initial phases of the design process. Our observations demonstrate that although experienced and non-experienced designers use different strategies to couple with the design task, both approached the task in a depth-first manner. These results should not be generalized, because few subjects were investigated, but point to the importance of being familiar with the knowledge domain – which poses a challenge for designers.  相似文献

Anatomy teaching is undergoing significant changes due to time constraints, limited availability of cadavers and technological developments in the areas of three-dimensional modelling and computer-assisted learning. This paper gives an overview of methods used to teach anatomy to undergraduate medical students and discusses the educational advantages and disadvantages of using three-dimensional computer models. A ‘work in progress’ account is then given of a project to develop two Web3D resources to enhance undergraduate tuition of the nervous system. Our approach is to support existing curricula using advanced modelling tools and a variety of delivery mechanisms.  相似文献

Because scaffolding is a crucial form of support for students engaging in complex learning environments, it is important that researchers determine which of the numerous kinds of scaffolding will allow them to educate students most effectively. The existing literature tends to focus on computer-based scaffolding by itself rather than integrating it with teacher support. This study examined students' inquiry learning skills and content knowledge when they utilized a virtual learning environment called Supervolcano: Kikai Caldera. The present study specifically explored how the timing of teacher-based metacognitive scaffolding in combination with different types of computer-based procedural scaffolding affected students’ science inquiry learning. To answer this question, a 2 × 2 factorial design was conducted. One factor examined continuous and faded computer-based procedural scaffolds, and the other factor investigated early and late teacher-based metacognitive scaffolds. Students who received both continuous computer-based procedural scaffolding and early teacher-based metacognitive scaffolding performed best in acquiring scientific inquiry skills. Students using both faded computer-based procedural and early teacher-based metacognitive scaffolding had the worst performance in learning scientific inquiry skills. However, although we applied different types of scaffolding, the results showed no statistically significant difference among the groups' science learning knowledge.  相似文献

The main purpose of this study is to design a “Courseware Development Model” (CDM) and investigate its effects on pre-service teachers' academic achievements in the field of geography and attitudes toward computer-based education (ATCBE). The CDM consisted of three components: content (C), learning theory, namely, meaningful learning (ML), and multimedia (M). The CDM is designed to show the synthesis of the C and M components under ML. In this study, an experimental design including pre-test and post-test groups is used to define the efficiency of the CDM. There are 31 pre-service teachers in the control group, 28 pre-service teachers in the meaningful learning theory group-ML, and 30 pre-service teachers in GTC group that uses geography teaching courseware-GTC based on the CDM. The results of the analysis indicate that the courseware is quite effective, improving pre-service teachers' academic achievements as well as their ATCBE scores. The results also suggest that the new model has an appropriate structure for courseware design.  相似文献

This article proposes a mathematical model of Intelligent Tutoring Systems (ITS), based on observations of the behaviour of these systems. One of the most important problems of pedagogical software is to establish a common language between the knowledge areas involved in their development, basically pedagogical, computing and domain areas. A mathematical model, like the one proposed here, can facilitate the integration of these different areas, as it defines the elements that constitute the system and defines the technological tools to implement it. The article presents an example demonstrating how the formalization was used to design the adaptive mechanism of an ITS to adapt its Interface Module to some student characteristics.  相似文献

At most Universities throughout the world Computer Aided Design is taught using commercial programs more suitable for business and industry than for teaching. This led us to write our own design program (GIcad) starting from the best-known standards on the market, but always avoiding unnecessary commands in the first steps of the learning process. GIcad constitutes a tool with a multitude of help messages to facilitate student self-training, it is very intuitive and has an attractive and dynamic graphic interface with a design that does not put off the beginner with a lot of options and commands.  相似文献

This study examined computer game development as a pedagogical activity to motivate and engage students in curriculum-related literacy activities. We hypothesized that as a consequence, students would improve their traditional reading and writing skills as well as develop new digital literacy skills. Eighteen classes of grade 4 students were assigned to either an experimental or control group. Both groups studied the same curriculum unit over a 10 week period, however, in addition the experimental group developed computer games related to the unit using a game development shell. An analysis of pre- and post-unit scores on two standardized literacy test batteries revealed that the experimental students performed significantly better on one of the subtests, a measure of logical sentence construction (p = .002). Field notes and teacher interview data indicated that game development helped improve student content retention, ability to compare and contrast information presented, utilize more and different kinds of research materials including digital resources, editing skills, and develop an insight into questioning skills.  相似文献

The rapid advance of information and communication technologies (ICT) has important impacts on teaching and learning, as well as on the educational assessment. Teachers may create assessments utilizing some developed assessment software or test authoring tools. However, problems could occur, such as neglecting key concepts in the curriculum or having disproportionate course topics distribution, when teachers create assessments or test items. This study proposes a novel approach, which uses knowledge map with appraisal of concept weights and other ICTs, and implements an assessment system KMAAS to help primary school teachers in Taiwan, or elsewhere, create educational assessments properly. When compiling an assessment, KMAAS ensures that teachers can include all important course concepts intended for assessing and maintain correct balance between course concepts among test items. It does so first by analyzing course material of the assessment range and displaying a concept-weight-annotated knowledge map which concretize and visualize the importance of and the relationships among concepts in the range. It then analyzes the test sheet which is being complied and displays another similar real-time updated knowledge map containing balance between course concepts among the test items. Teachers may cross-refer to these maps to help them adjust concept balances and even select appropriate test items from test banks. The system has being evaluated in both the accuracy of learning concepts extraction and the degree of user satisfaction, as measured by questionnaires given to the teachers who tested the system. The promising results confirm the feasibility of this system in helping teachers compile their educational assessments easily and precisely. Other results of the formative evaluations on techniques have being used to improve the system in order to make it more effective and efficient. The methodology and technologies KMAAS employed are all well developed and are domain independent, which makes it highly flexible to transfer to other course subject domain too.  相似文献

Assessments, embedded with teachers’ implicit (i.e. tacit) domain knowledge, play an important role in evaluating ’comprehension of a subject. The knowledge on the importance of both the concepts and their relationships of a subject, if captured, made explicit, and shared around, may greatly help teachers construct more effective assessments. This study establishes a methodology to accumulate tacit knowledge of specific topics from collected assessments by using an implicit knowledge extraction mechanism and, visualises the overall importance distribution of concepts by using knowledge maps for helping teachers compile their assessments. Several two stage experiments, scheduled for one semester, were conducted in the third grade natural science courses at elementary schools in Taiwan. Eighteen teachers who actually teach the courses participated in the experiments, and thirty students were in each course. In the first stage, teachers compiled assessments without using IKMAAS’s knowledge map features while in the second stage, they did use them. System usage records, questionnaires and interview results were used for evaluating the usability of the methodology and the satisfaction of using IKMAAS. The results indicate the potential of the methodology, as each of the teachers agreed that the visualised assessment knowledge helped them to comprehend the proportions of concepts they intended to test easily and, additionally, helped them to clearly notice concepts they may have ignored. Yet the results in this study also show the potential of using knowledge maps and knowledge accumulating methodology in pedagogy paradigm.  相似文献

The research presented in this paper reaches towards a better theoretical understanding of how students in higher education currently take notes, how this process is evolving in the digital age to include information assimilation, and the kinds of support students need to be successful with their changing academic tasks. To gain insight into these questions, we triangulated three major and distinct user studies. First we interviewed 70 university students from various disciplines across campus, and we administered questionnaires to these same students, receiving back a total of 68. Our second study was based on participant observation whereby we “shadowed” 32 university students for 2–3 h each as they went about their normal academic business around campus. Lastly, we conducted a broader-based questionnaire with 280 students from a wider campus demographic than our first survey. We sought a diverse population for our research, and were able to include students from the disciplines of Business, English, Computer Science, Chemistry, Psychology, Pharmacy and Biology in one or more of the studies. We discovered how closely students are connected to technology and how they are adapting to changing expectations, current issues they have completing their academic tasks, how they view traditional notetaking versus electronic notetaking, and evidence that they are engaging more and more in the process of information assimilation. From these results, we conclude that students in higher education might accomplish certain tasks more effectively and efficiently with a well-designed software system that provides access to a centralized set of notes from different locations on campus and beyond. After identifying functional requirements for the system we envision, we preview our initial low-fidelity prototypes, and discuss feedback we gathered on these designs from a set of user focus groups.  相似文献

The purpose of this study was to investigate the effectiveness of a haptic augmented simulation in learning physics. The results indicate that haptic augmented simulations, both the force and kinesthetic and the purely kinesthetic simulations, were more effective than the equivalent non-haptic simulation in providing perceptual experiences and helping elementary students create multimodal representations of the movements of gears. However, in most cases, force feedback was needed to construct a fully loaded multimodal representation that helps students to comprehend later instruction with less sensory modalities. In addition, the force and kinesthetic simulation was effective in helping to transfer knowledge to new learning situations. These findings suggest that it is important to help elementary students make a solid cognitive grounding with the use of a perceptual anchor.  相似文献

This study focuses on carrying out weighted digraph-based mathematical construction of hypermedia and user navigation on hypermedia and making a presentation of “weighted” forms of known stratum and compactness. In the instructional Web design researches, the structural analysis of navigation on the hypermedia is important in modeling the behaviors that the learners perform while using this kind of media. Therefore, new conceptions of the presented usage of new measures towards this goal are also discussed within the scope of our study.  相似文献

We present a comparative study of a literature review of 326 selected contributions (Buteau, Marshall, Jarvis & Lavicza, 2010) to an international (US, UK, Hungary) survey of mathematicians (Lavicza, 2008) regarding the use of Computer Algebra Systems (CAS) in post-secondary mathematics education. The comparison results are organized with respect to four emerging themes: Issues in CAS integration and mathematical learning, the notion of mathematical literacy, diverse uses of CAS by practitioners, and, potential benefits of CAS integration. Our analysis suggests that the results of the literature review strongly support the findings and conclusions of Lavicza’s international survey. We contend that Lavicza’s concluding statement about the need to more holistically examine technology integration in post-secondary mathematics departments was significantly realized through both of the compared studies.  相似文献
