Haptics-Augmented Simple-Machine Educational Tools 总被引：1，自引：1，他引：1
Williams Robert L. Chen Meng-Yun Seaton Jeffrey M. 《Journal of Science Education and Technology》2003,12(1):1-12
This paper describes a unique project using commercial haptic interfaces to augment the teaching of simple machines in elementary school. Haptic interfaces provide a sense of touch and force to the human user from a virtual model on the computer. Since force is central to the teaching of simple machine, we believe that the use of haptics in virtual simple-machine simulations has the potential for deeper, more engaging learning. A software has been developed and is freely available on the Internet. HTML tutorials have been developed to support these haptics-augmented software activities in the teaching and learning of simple machines in elementary school. The pilot study results are reported, which yielded positive feedback and suggestions for project improvement from elementary school students and teachers. 相似文献

Research practice partnerships: a strategy for promoting evidence-based decision-making in education
Laura Wentworth Christopher Mazzeo Faith Connolly 《Educational research; a review for teachers and all concerned with progress in education》2017,59(2):241-255
AbstractBackground: In the United States, an emphasis on evidence-based decision-making in education has received renewed interest with the recent passage of the Every Student Succeeds Act. However, how best, in practice, to support the use of evidence in educational decision-making remains unclear. Research Practice Partnerships (RPPs) are a popular strategy for cultivating evidence-based decision-making among educators, but understanding the ways in which partnerships can influence educators’ use of research evidence in their decision-making is limited.Purpose: This paper explores the influence that Research Practice Partnerships can have on educators’ evidence-based decision-making.Sources of evidence: A framework is offered for examining the impact of Research Practice Partnerships on behaviours such as educators’ evidence-based decision-making, in the context of school and district improvement efforts. The framework suggests a host of intermediary and long-term outputs: for example, the ‘mindsets’ of researchers and practitioners which are most conducive to enabling evidence-based decision-making among those engaged in Research Practice Partnerships. We explore this framework through short illustrations of the experiences of three Research Practice Partnerships, contextualising the ideas within the literature, and presenting the process of our design and pilot of a survey instrument used to examine the perceived impact of Research Practice Partnerships.Main argument: We argue that participants’ self-reported behaviours and perceptions are important elements in examining the influence of Research Practice Partnerships on educators’ evidence-based decision-making. Additionally, this paper examines the potential benefits and challenges of attempting to measure the outputs and outcomes of a Research Practice Partnership using a survey measure.Conclusions: The process of developing the pilot survey suggests that certain conditions in Research Practice Partnerships may be more conducive to the development among educators of behaviours, mindsets and perceptions associated with evidence-based decision-making. 相似文献

The rapid development of information and communication technologies has enabled the development of interfaces, which allow the recognition of the gestures and movements of the user. These interfaces, due to their affordable prices, are available to a wide range of users. They are called natural user interfaces (NUI). NUI are commonly used in game consoles and electronic devices, such as smartphones and tablets. We used the Kinect sensor from Microsoft in our studies to identify the movements and gestures of the user. This interface was used by us in teaching Chemistry in a Middle School and High School by developing a virtual chemical laboratory, which is based on a system of hand movements. We have analyzed the gestures and movements of the virtual chemical laboratory user to determine how they raise the effectiveness in chemical education. The results show how much better students work with a virtual laboratory, when studied by us in chemical areas, that concerned remembering information, understanding information, applying their experience in situations familiar to them from school and in solving chemical problems. 相似文献

While haptics (simulated touch) represents a potential breakthrough technology for science teaching and learning, there is relatively little research into its differential impact in the context of teaching and learning. This paper describes the testing of a haptically enhanced simulation (HES) for learning about buoyancy. Despite a lifetime of everyday experiences, a scientifically sound explanation of buoyancy remains difficult to construct for many. It requires the integration of domain-specific knowledge regarding density, fluid, force, gravity, mass, weight, and buoyancy. Prior studies suggest that novices often focus on only one dimension of the sinking and floating phenomenon. Our HES was designed to promote the integration of the subconcepts of density and buoyant forces and stresses the relationship between the object itself and the surrounding fluid. The study employed a randomized pretest–posttest control group research design and a suite of measures including an open-ended prompt and objective content questions to provide insights into the influence of haptic feedback on undergraduate students’ thinking about buoyancy. A convenience sample (n = 40) was drawn from a university’s population of undergraduate elementary education majors. Two groups were formed from haptic feedback (n = 22) and no haptic feedback (n = 18). Through content analysis, discernible differences were seen in the posttest explanations sinking and floating across treatment groups. Learners that experienced the haptic feedback made more frequent use of “haptically grounded” terms (e.g., mass, gravity, buoyant force, pushing), leading us to begin to build a local theory of language-mediated haptic cognition. 相似文献

ABSTRACT Studies on teacher education networks have unanimously pointed out that networks which allow teachers to share their experience, problems and curriculum materials enhance collegiality and professional growth. This paper reports findings of the implementation of TeleNex (Teachers of English Language Education Nexus) which is a teacher education network linking the Teachers of the English Language Education Centre (TELEC) set up at the University of Hong Kong with secondary schools. It points out that for a network of this nature to be effective, we have to take into consideration in the implementation process social factors such as user needs, motivation, background and psychology as well as user proficency in computer skills. The discussion will be illustrated with data from questionnaires, interviews, meetings, and messages on the network. 相似文献

It is generally accepted that informative and timely feedback is important to a student's learning experience within higher education. In the study of commercial digital games it has also become increasingly understood that games are particularly good at providing effective feedback of this form to gameplayers. We discuss recent game based learning research that attempts to harness the motivating qualities of digital games to inform the design of educational technology. Results from this research demonstrate student participation and performance can be improved by providing Game‐Based Feedback (GBF) to students. The GBF approach awards points to students for the successful completion of tasks throughout a course of study. Points and achievements accumulated over time builds a profile that provides a student with a potentially powerful representation of their educational identity. In this paper, we argue that virtual worlds are particularly suitable for this form of GBF and can further enhance a student's understanding of their educational standing. We outline a Virtual Learning Landscape (VLL) design that is embedded within a multi‐user virtual environment, where educational feedback is supplied to students via their avatar and a virtual world's landscape. The core structural principles of the proposed VLL are explained and several examples of the use of the VLL are provided to illustrate the system. 相似文献

伴随大数据、学习分析技术的发展,在线作业成为当前教育科技产品的重要形式,但是有关在线作业的用户体验研究并不多。文章采用技术接受模型来研究初中生和家长的在线作业用户体验及其影响因素,并结合相关研究中的教师用户体验进行比较分析,研究发现:易用性对学生和家长的在线作业使用无显著影响,对教师有影响;有用性是教师和家长更为关心的,而学生对此无感;社会影响和自我学习管理对学生和家长在线作业使用呈显著影响。基于此,文章对在线作业推广应用进行了反思,认为在线作业需避免成为强化应试的工具;教师要适应新的“把关人”角色;在线作业开发需更多地转向学生用户设计,以增强其学习体验。 相似文献

A recent powerful idea in the design of Web-based learning environments is the usage of virtual places. The employment of interface metaphors is one of the approaches enabling inexperienced users to feel comfortable in such virtual environments. We have designed a Virtual Environment for Distance Education and Training (VEDET), which provides basic virtual spaces, resources, and services. In this paper we discuss the user interface of two Web-based distance learning courses Business on the Internet and Business English, developed on the basis of VEDET. A web-based learning environment has been implemented to support the delivery of these courses. Two examples of interface metaphors have been developed and adopted, each presenting a coherent image of the environment. © IFIP, published by Kluwer Academic Publishers 相似文献

We designed and piloted a technical communication course for software engineering majors to take concurrently with their capstone project course in software design. In the pilot, one third of the capstone design course students jointly enrolled in the writing class. One goal of the collaborative courses was to use writing to improve the usability of students’ software. We studied the effects of writing on students’ user‐centered beliefs and design practices and on the usability of their product, using surveys, document analyses, expert reviews, and user test results. When possible, we compared the usability processes and products of teams who did and did not take the writing class. Our findings suggest that the synergy of this interdisciplinary approach effectively sensitized students to user‐centered design, instilled in them a commitment to it, and helped them develop usable products. 相似文献

Virtual worlds are gaining momentum as a platform for delivering simulation‐based educational experiences to students. However, a key aspect of virtual world‐based education that has received little attention is recording and analyzing students' in‐world actions. This capability is essential for assessing what students have learned through their simulation experience, and engaging the students in post‐simulation reflective learning. In this research, we present a framework for recording and analyzing students' actions in a virtual world. This framework is based upon pedagogical theories of exploratory and experiential learning, and is defined in a virtual‐world agnostic manner. The framework consists of two parts: (1) the Avatar Capabilities Model, which defines the educationally relevant actions that a student can take within a virtual world and (2) the Simulation Capture and Analysis toolkit that records and analyzes these actions, from an educational perspective. These analyses provide instructors with systematically collected evidence of the students' actions during their virtual world experience. This alleviates the need for instructors to directly observe students, thereby allowing for the scaling‐up of virtual worlds use in education. We have demonstrated the usefulness of the tool via a pilot study, with two students, in an emergency medical education context. 相似文献

The focus of this paper is on the contribution that active touch sensory feedback offered through physical or virtual (with haptic feedback) manipulatives, makes to students' learning through science experimentation. Both theoretical perspectives and empirical evidence are presented. The theoretical perspectives were drawn from two types of theories, namely embodied cognition and additional (touch) sensory channel, which were associated with the use of physical and virtual manipulatives for learning purposes. The empirical evidence was drawn from two different lines of research. The first line of research involves studies that have focused on comparing physical manipulatives and virtual manipulatives (without the provision of haptic feedback), whereas the second involves studies that have focused on comparing virtual manipulatives with and without the provision of touch sensory (haptic) feedback. Both theories supply strong arguments for providing touch sensory feedback during science experimentation, whereas the empirical research outcomes show that providing touch sensory feedback is not always a prerequisite for learning science through experimentation. Those instances for which touch sensory feedback does appear to be a necessity for learning science through experimentation are identified. However, science education studies are limited within the aforementioned research areas. In addition, their findings are inconsistent, especially for the research focused on comparing virtual manipulatives with and without haptic feedback. The latter makes it difficult to arrive at a solid framework that depicts when and how touch sensory feedback should be offered to students for learning science through experimentation. The article concludes with suggestions for future research that would contribute towards development of such a framework. 相似文献
