A Soft Computing Approach to Quality Evaluation of General Chemistry Learning in Higher Education

In contemporary societies higher education must shape individuals able to solve problems in a workable and simpler manner and, therefore, a multidisciplinary view of the problems, with insights in disciplines like psychology, mathematics or computer science becomes mandatory. Undeniably, the great challenge for teachers is to provide a comprehensive training in General Chemistry with high standards of quality, and aiming not only at the promotion of the student’s academic success, but also at the understanding of the competences/skills required to their future doings. Thus, this work will be focused on the development of an intelligent system to assess the Quality-of-General-Chemistry-Learning, based on factors related with subject, teachers and students

Something for everyone? The different approaches of academic disciplines to Open Educational Resources and the effect on widening participation

This article explores the relationship between academic disciplines‘ representation in the United Kingdom Open University‘s (OU) OpenLearn open educational resources (OER) repository and in the OU‘s fee-paying curriculum. Becher‘s (1989) typology was used to subdivide the OpenLearn and OU fee-paying curriculum content into four disciplinary categories: Hard Pure (e.g., Science), Hard Applied (e.g., Technology), Soft Pure (e.g., Arts) and Soft Applied (e.g., Education). It was found that while Hard Pure and Hard Applied disciplines enjoy an increased share of the OER curriculum, Soft Applied disciplines are under-represented as OER. Possible reasons for this disparity are proposed and Becher‘s typology is adapted to be more appropriate to 21st-century higher education

The works metallurgist: An evaluation of a CAL package on phase diagrams

The Works Metallurgist is used in the Open University course: Materials — Engineering and Science. It is being evaluated as part of a larger study of CAL teaching in Science and Technology at the Open University. With 540 students, the course provides a sufficiently large sample for a range of evaluation methods to be employed in a variety of settings (e.g. home, residential school). The methods used include questionnaires, attitude scales and pre/post achievement tests, observations and interviews. The focus of the evaluation exercise is on the effectiveness of CAL in contributing to student learning. The issue of the educational quality of the program and its instructional features are considered in this paper, in association with the goals of the program

Peer review innovations in Humanities: how can scholars in A&H profit of the "wisdom of the crowds"?

Though supported by a large number of scholars in Scientific, Technical, and Medical (STM) disciplines traditional peer review does not live up to the needs of an efficient scholarly communication system and of quality research control. Therefore journals in STM are experimenting different forms of refereeing in combination with more traditional peer review system. Such is the case of PLoSONE, Biology Direct, Atmospheric Chemistry and Physics, Electronic Transactions on Artificial Intelligence, and JIME. However in STM disciplines public peer review is not regarded an alternative to more traditional quality certification forms. It may be the case in the Arts & Humanities. In A&H publishing system peer review is by far a less common practice. Therefore the adoption of a social peer review process could be very useful to foster research in humanities. Scholars in A&H can profit of the interactive evaluation forms of the public peer-review to strengthen the scholarly debate, to foster active international and interdisciplinary discussions, to focus social attention on topics in Humanities, to broaden the borders of the cultural and intellectual discourse among non-scholars (public debate). This paper will provide some examples of how social peer review has been adopted by innovative communities of scholars in humanities to publish new experimental digital book models. In the digital environment the concepts of “document”, of “completeness of a document” and of “evaluation” is fast changing. In a close future in scholarly publishing it might become possible to overcome the rigid distinction between ex-ante and ex-post evaluation as the evaluation process might become an enduring part of the text itsel

Using an online formative assessment framework to enhance student engagement: a learning outcomes approach

Students learn best when they are fully engaged in the learning process, are motivated to test their current level of learning against known standards, and are offered targeted and timely support to help address subsequent personal learning needs. The most usual way to do this is through the use of assessment, but this in itself can act as an overbearing influence on what and how students learn, rather than providing an holistic support mechanism that encourages continuous reflective learning. Summative assessment provides a quantitative measure of learning at specific points in time, but may not encourage students to focus on specific strengths and weaknesses in need of attention. Formative assessment can provide specific reflective and feed-forward support, but given the time-poor nature of many students, is this perceived as a useful part of the learning process? This paper presents an overview of work in progress (funded by Centre for Open Learning in Maths, Science, Computing and Technology CETL at The Open University), on the development and implementation of an online interactive formative assessment framework, that has designed from a constructivist perspective, to promote student engagement and understanding of academic progression, using an learning outcomes approach. The framework specifically aims to enhance student awareness, understanding and recognition of competency levels, and to allow testing of ongoing academic progress at predetermined and self-selected points throughout the year. Each assessment makes explicit links to other components of the course including the summative assessment strategy, as a means of providing an integrated approach to learning. By working through the formative assessments it is hoped that students will become more self-directed and confident in their learning skills and abilities, which in turn should improve retention. The framework uses OpenMark (a web-based system developed within the Open University) in which students have up to three attempts to correctly answer each question, and are offered instantaneous and targeted feedback after each incorrect attempt. The system collects information on the answers submitted, and the time taken to complete each question, offering valuable insight into how (and which) students are engaging with the assessment and course materials. This data permits new targeted feedback to be added in response to common errors, as well as additional support mechanisms to be incorporated in response to specific skills or content that is poorly demonstrated. All feedback in the framework is formative, commenting on how well each of the learning outcomes tested over a period of study has been demonstrated, as well as the overall level of academic competency attained at that point in time. At present, the framework encompasses seven interactive assessments (linked to fortnightly periods of study), consisting of ten variable-format questions (set at two levels of academic complexity). A planned eighth assessment will randomly select questions from preceding assessments, offering an instantaneous interactive revision tool. Preliminary results indicate that students not only rate the assessments as enjoyable, but are revisiting specific assessments as a means of enhancing previous outcomes and checking their progression on aspects they previously had difficulties with
