Interviewing is a critical skill for systems analysts. This article describes an experiment using student actors as interviewees for in‐class exercises to teach interviewing in the junior‐level systems analysis course. The experiment proved beneficial to the class, to the actors, and to the senior IS majors who helped the actors prepare.  相似文献

如何利用移动设备的位置识别功能开发创新性的移动应用系统,是众多研究者和商业应用开发者关注的焦点。基于位置识别的移动学习系统5R自适应框架为实现自适应移动学习环境提供了一套解决方案和标准化结构。5R自适应框架能够根据学习者、位置、时间、移动设备等因素自动生成学习者所需要的学习内容,增强学习者与学习情境之间的交互。5R自适应框架的实施需要描述基于位置的学习内容并使之标签化,建立自适应约束条件和学习内容之间的关系。在基于位置识别的地理课实地考察移动学习过程中,5R自适应框架能够很好地支持这一应用,而且在实现过程中体现出高度的灵活性。  相似文献

It is now possible to create flexible learning environments without time and distance barriers on the internet. However, research has shown that learners typically experience isolation and alienation in online learning environments. These negative experiences can be reduced by enhancing social presence. In order to better facilitate the perceived social presence in online classrooms, this study presents a framework developed from the social cognitive theory for investigating social presence and its relationships with relevant factors. An instrument with sufficient reliability and validity was developed to measure these factors. A formal questionnaire-based survey was carried out among learners with previous learning experiences in online learning environments. A total of 522 valid samples were collected from three schools and analyzed using structural equation modeling to examine the proposed framework and hypotheses. The results show that user interface and social cues have significant effects on social presence. User interface also has significant effects on social cues. Moreover, this study evidenced that social presence has significant effects on learning interaction which in turn has significant effects on learning performance. Finally, implications of the findings were discussed for further research directions and practical applications.  相似文献

ABSTRACT

Teacher support for students in ubiquitous learning environments is challenging owing to physical distance and a lack of reliable real-time multimedia-rich communication. This is further complicated because the learning process is dynamic and problems need quick resolution. Given these challenges, this study proposes an architecture for a teacher facilitation support system. The system was implemented in the form of an interactive teacher dashboard. The interface also generates possible solutions to learning challenges while leaving the ultimate decision up to the teacher. The system feasibility was tested by work-through scenarios designed and validated by two experts. The system usability was evaluated using the System Usability Scale by 40 potential users. The ?ndings revealed that the dashboard has good feasibility and usability for providing teachers relevant information about their students’ learning progress in ubiquitous learning environments. It also enabled opportunity for pedagogical intervention when needed.  相似文献

Although learning styles are considered as an important factor in education, students often have to learn in courses that do not support their learning styles. A challenge for technology facilitated learning is therefore to assist and help students to cope with courses that do not match their learning styles by training and developing their less preferred skills. In this paper, the interactions between students’ learning styles, their behaviour, and their performance in an online course that is mismatched regarding their learning styles were analysed. The results show which learners need more help in mastering mismatched courses, help in getting a better understanding about how students with good performance record and poor performance record learn with respect to their learning styles, and provide information about how to identify learners who might have difficulties in learning based on their behaviour.  相似文献
