A research strategy for the dynamic study of students' concepts and problem solving strategies using science software 总被引：1，自引：0，他引：1
Microcomputers and appropriate software have the potential to help students learn. They can also serve as appropriate media for investigating how students learn. In this article we describe a research strategy examining learning and behavior when students interacted with microcomputers and software. Results from two preliminary studies illustrate the strategy. A major feature of the strategy included recording students interacting with microcomputer software interfaced with a VCR. The VCR recorded the video output from a microcomputer and students' verbal commentary via microphone input. This technique allowed students' comments about their observations, perceptions, predictions, explanations, and decisions to be recorded simultaneously with their computer input and the display on the microcomputer monitor. The research strategy described can provide important information about cognitive and affective behaviors of students engaged in using instructional software. Research studies utilizing this strategy can enhance our understanding of how students develop and employ important concepts and scientific relationships, how students develop problem-solving skills and solve problems, and how they interact with instructional software. Results of such studies have important implications for teaching and for the design of instructional software. 相似文献

The Telesoftware and Education Project, which was set up in 1980 by the BBC, the IBA and Brighton Polytechnic, demonstrated the feasibility of using broadcast transmissions to distribute computer programs as teletext pages, to be downloaded (i.e. recorded) onto a microcomputer in school. The success of the project led to the setting up of a Telesoftware and Primary Education Project, to distribute software to the area of education in which programming expertise is least often available. Telesoftware is not only a means of distributing stand‐alone software but can also be coupled with schools’ broadcasts and can read relevant information from any page of teletext, providing an educational television ‘package’. The project provides a link between schools and programmers and functions as a pre‐ and post‐broadcast evaluation team. The initial feedback from schools has been very positive and it is hoped that the broadcasting of high quality, relevant telesoftware will be a useful TV service in the future. 相似文献

This paper presents the results after four years of running of an instructional method that utilizes free/libre open source software (FLOSS) projects as tools for teaching software engineering in formal education. In the last four academic years, a total of 408 juniors majoring in Informatics (in a 4-year program) participated in the study, assuming the roles of requirements engineers, testers, developers, and designers/analysts. Students appreciated the benefits gained by the method and identified aspects that require further improvement. In the paper, we present (a) the details of our method, (b) students’ opinions as recorded through a questionnaire including both closed and open ended questions, and (c) conclusions on how the use of FLOSS projects can be applied, and be beneficial for the students. 相似文献

This paper presents a framework (FILTWAM (Framework for Improving Learning Through Webcams And Microphones)) for real-time emotion recognition in e-learning by using webcams. FILTWAM offers timely and relevant feedback based upon learner's facial expressions and verbalizations. FILTWAM's facial expression software module has been developed and tested in a proof-of-concept study. The main goal of this study was to validate the use of webcam data for a real-time and adequate interpretation of facial expressions into extracted emotional states. The software was calibrated with 10 test persons. They received the same computer-based tasks in which each of them were requested 100 times to mimic specific facial expressions. All sessions were recorded on video. For the validation of the face emotion recognition software, two experts annotated and rated participants’ recorded behaviours. Expert findings were contrasted with the software results and showed an overall value of kappa of 0.77. An overall accuracy of our software based on the requested emotions and the recognized emotions is 72%. Whereas existing software only allows not-real time, discontinuous and obtrusive facial detection, our software allows to continuously and unobtrusively monitor learners' behaviours and converts these behaviours directly into emotional states. This paves the way for enhancing the quality and efficacy of e-learning by including the learner's emotional states. 相似文献

This study explored whether over-the-counter continuous voice recognition software could be used to support the delivery of a standardized reading curriculum to adults with low-level literacy skills. Three primary questions were addressed in the study. First, how readily could mass-market continuous voice recognition software programs be adapted for use in adult literacy training? Second, what role(s) might the voice recognition technology play in facilitating the computer-based delivery of a standard text-based reading curriculum? And third, does the use of the voice recognition software positively affect the technological skills and computing comfort levels of adults with low-level literacy skills? Five adults with low-level literacy skills completed the computer-based curriculum, using the voice recognition software to practice and check their reading and writing efforts. A literacy tutor guided the participants through the curriculum, recorded and saved the participants' responses and videotaped the sessions for subsequent analysis. The findings reported here suggest that currently available over-the-counter continuous voice recognition technology, while essentially effective and accurate with fluent readers, is not yet ready, as a stand-alone system, to meet the needs of these adults with low-level literacy skills. The voice recognition software was most effective when it was used in the presence of a tutor. Having tutors provide on-going and immediate support to learners was a vital component of literacy training in this computer-based environment. In general the computer-based programs seemed to provide participants with a `motivational boost'. Specifically, the computer-based lessons helped develop participants' technological skills and confidence levels and promoted sustained focus on instructional tasks. Implications associated with these findings for future research with voice recognition software and adult literacy training are discussed. 相似文献

To examine interface issues in an educational software program, we recruited twenty-two users in health sciences departments for a usability study. Using the GramStain-Tutor™ (GST) CD-ROM, these users performed tasks in navigating the program and using various interactive features. Their actions and comments were recorded with a digital video recorder and an audio recorder. The main results of our study are: (a) the majority of the users did not use the multiple navigational options available in the program; (b) navigational patterns differed based on the training background and content knowledge of the users; (c) several visual cues critical to program use were not discovered by the majority of the users; and (d) icons representing specific functions were not intuitive from users' perspectives. We demonstrated how a usability study of a relatively small number of users can identify specific problems in interface design. We recommend these interface problems be addressed before conducting educational studies that examine how educational software programs affect student learning. 相似文献

The research described in this chapter draws upon theories of situated cognition to examine the kinds of knowledge used by motel front office personnel to manipulate computer software as a tool for everyday data work tasks. Participants’ use of computer software was recorded directly from the computer terminal to videotape by means of a conversion device (Genlock). Simultaneously, a sound recording of the workplace “event” occurring was placed on the videotape. In addition, a video recording was made of the broader workplace episodes. The results suggest that although generic competencies could be identified, many of the competencies were context-specific. At a more concrete level of operation, little commonality was found in the strategies used across sites in undertaking what appeared to be the same activity. Drawing on cognitive theory, the findings are taken to support the view that generic knowledge may be impossible to apply if the user is unable to inter-relate this knowledge with the domain-specificity of the knowledge that is actually used in practice in work sites. 相似文献

This paper summarizes the RESOLVE approach for introducing component-based software engineering (CBSE) early in the undergraduate CS curriculum, and an evaluation of its impact at two institutions. Principles taught include a modular style of software development, human understandable, yet formally-specified component behavior, maintainability, as well as ‘classical’ issues such as efficiency analysis and reasoning. Qualitative and quantitative evaluations of student outcomes and end-to-end changes in student attitudes show mostly positive results that are statistically significant, confirming that (1) CBSE principles can be taught without displacing essential classical principles, (2) students can understand and reuse components based on mathematical specifications, and (3) student attitudes towards software engineering can be altered in directions heretofore often assumed to be difficult to achieve. 相似文献

Abstract Many activities from the infant class curriculum may be enhanced by realising them in the interactive context of a computer environment. This raises the question of whether young children can make choices among such activities that would reflect an awareness of their difficulty and a motivation to master them. In this research, infant class pupils were provided with software that offered unconstrained opportunities to select a range of related activities and the level of difficulty at which they would be tackled. Choices and response times were automatically recorded over a period of three weeks. These choices remained stable throughout that time and were biased towards the easiest options. There was some improvement in performance although little evidence of choice strategies that could be effective in driving such improvement. There was no evidence of sex differences in frequency of using the computer. 相似文献

Summary This paper has shown how XML (extensible Markup Language) can be used to mark up content. Since XML documents, with meaningful
tags, can be interpreted easily by humans as well as computers, they are ideal for the interchange of information. Because
XML tags can be defined by an individual or organization, XML documents have proven useful in a variety of areas including
chemistry, mathematics, music, literature, graphics, eCommerce and educational technology. This paper demonstrated a simple
example of how XML could be used for developing eLearning applications where the content and presentation software can be
separated from one another. This separation facilitates the maintenance, reuse and repurposing of both the content and the
presentation software 相似文献

The failure of many instructional design initiatives is often attributed to poor instructional design. Current instructional design models do not provide much insight into design processes for creating e-learning instructional solutions. Given the similarities between the fields of instructional design and software engineering, instructional designers could employ the ideas and techniques employed in software engineering to improve their design solutions. Software engineering development and project management methodologies can be employed to develop effective e-learning solutions. Furthermore, software engineering design principles used to develop high-quality software can be applied to planning and enhancing instruction. Fundamental software design concepts, such as abstraction, modularity, reusability, compatibility, extensibility, scalability, and maintainability are all important factors that can potentially lead to the development of high quality instructional solutions. This paper explores the possibility to integrate software engineering design principles into instructional design for e-learning solutions, which not only augment the generic instructional design approach with the best practices from the field of software engineering, but also make the development process more productive and efficient. Finally, this paper illustrates how all of the software engineering design principles are interrelated and can be realized in practice to enhance the quality of instruction. 相似文献

The Bollen-Stine bootstrap can be used to correct for standard error and fit statistic bias that occurs in structural equation modeling (SEM) applications due to nonnormal data. The purpose of this article is to demonstrate the use of a custom SAS macro program that can be used to implement the Bollen-Stine bootstrap with existing SEM software. Although this article focuses on missing data, the macro can be used with complete data sets as well. A series of heuristic analyses are presented, along with detailed programming instructions for each of the commercial SEM software packages. 相似文献
