In this paper, a dropout prediction method for e-learning courses, based on three popular machine learning techniques and detailed student data, is proposed. The machine learning techniques used are feed-forward neural networks, support vector machines and probabilistic ensemble simplified fuzzy ARTMAP. Since a single technique may fail to accurately classify some e-learning students, whereas another may succeed, three decision schemes, which combine in different ways the results of the three machine learning techniques, were also tested. The method was examined in terms of overall accuracy, sensitivity and precision and its results were found to be significantly better than those reported in relevant literature.
a case study of the Linux operating system. Being open source software, this exemplifies the collaborative project, highlighting the significance of good communication in a distributed environment. Part V pertains to online communities. It examines interpersonal communication and socialisation within online communities. Part VI deals with virtual worlds and the tools used to create virtual worlds. Massive multiplayer online role-playing games (mmorpgs) form a big industry nowadays, and a lot of software is being developed for education as well as entertainment. This section deals with muds (multi-user dungeons) and that highly successful product of Linden Labs, Second life. These virtual worlds can be so engrossing that the users treat them as real world.
Although e-learning has been thoroughly presented and analysed in recent years, this paper aims to present a new concept, about web-based learning used as a tool to provide ‘products’ education’ for customers, and the ways enterprises of the financial sector, may use it in order to promote their brand name and services by affecting crucial factors like customer’s trust and loyalty.
This study focuses on a project, EMPATHY Net-Works, which developed a learning community as a means of encouraging women to progress into employment and management positions in the logistics and supply chain industries (LaSCI). Learning activities were organised in the form of a taught module containing face-to-face and online elements and e-mentoring with successful professional women in the LaSCI. In this particular research, we have used structuration theory, a social theory that concentrates on the relationships between human agency (micro-level) and social structures (macrolevel). We used structuration as an analytical tool to help us understand what happened within the project e-learning and e-mentoring processes. Our analysis suggests that there were two factors that influenced the way project participants carried out their learning activities: the first one being the issue of absence and presence in online environments, and the second one the issue of time frame changes for online users.
Proponents have marketed e-learning by focusing on its adoption as the right thing to do while disregarding, among other things, the concerns of the potential users, the adverse effects on users and the existing research on the use of e-learning or related innovations. In this paper, the e-learning-adoption proponents are referred to as the technopositivists. It is argued that most of the technopositivists in the higher education context are driven by a personal agenda, with the aim of propagating a technopositivist ideology to stakeholders. The technopositivist ideology is defined as a ‘compulsive enthusiasm’ about e-learning in higher education that is being created, propagated and channelled repeatedly by the people who are set to gain without giving the educators the time and opportunity to explore the dangers and rewards of e-learning on teaching and learning. Ten myths on e-learning that the technopositivists have used are presented with the aim of initiating effective and constructive dialogue, rather than merely criticising the efforts being made.
This paper presents a novel instructional model for e-learning and an evaluation study to determine the effectiveness of this model for teaching Java language programming to information technology specialists working for the Spanish Public Administration. This is a general-purpose model that combines objectivist and constructivist learning theories and is based on the concept of learning objective. The purpose of the evaluation study is to find out whether the results of using this distance learning instructional model to teach this subject are comparable to learning in a traditional face-to-face classroom, with the plus of eliminating travel and maintenance expenses of the public servants attending the course and also saving time. The learners, selected at random to participate in this study, were divided into three groups depending on the type of teaching/learning they received: traditional classroom, distance learning with virtualized course contents and distance learning based on the proposed instructional model. The results indicate that the grades and satisfaction levels were similar for learners taught using the proposed instructional model and learners taught in the traditional classroom. Moreover, they were substantially better than for distance learning with virtualized contents, although the mean course learning time is greater.
We designed an e-learning model to promote critical thinking about basic science topics in online communities of students during work placements in higher education. To determine the effectiveness and efficiency of the model we explored the online discussions in two case studies. We evaluated the quantity of the interactions by looking at quantitative data of the discussion ‘threads’ and we evaluated the quality of the discussion by content analysis of the individual messages. Both the procedural facilitation of the discussion and the instrument for content analysis were based on Garrison’s ‘Practical Inquiry model of Cognitive Presence’. Furthermore, we explored the experiences of the students and moderators by interviewing them and we organised their perceptions using the framework of an activity system. On the basis of the quantitative and qualitative data we conclude that the e-learning model was successful in establishing a dialogue among a group of students and an expert during work placements at different locations. The ‘Practical Inquiry model’ was useful in facilitating a sustained on-topic discourse involving critical thinking. Although the amount of critical thinking was moderate, the results suggest ways to increase integration and resolution activities in the online discussions.
The book takes into account the different experiences of teachers, with a chapter specifically about working with newly qualified teachers. There is also a chapter on coaching for the specialist, whether that is a subject specialist or a technical support person; this shows how every member of staff can benefit from and be included within the programme. And there is a chapter on evaluation (measuring impact)— such an important aspect of any coaching programme.
