Supporting the discoverability of open educational resources

Open Educational Resources (OERs), now available in large numbers, have a considerable potential to improve many aspects of society, yet one of the factors limiting this positive impact is the difficulty to discover them. This study investigates and proposes strategies to better support educators in discovering OERs, mainly focusing on secondary education. The literature suggests that the effectiveness of existing search systems could be improved by supporting high-level and domain-oriented tasks. Hence a preliminary taxonomy of discovery-related tasks was developed, based on the analysis of the literature, interpreted through Information Foraging Theory. This taxonomy was empirically evaluated with a few experienced educators, to preliminary identify an interesting class of Query By Examples (QBE) expansion by similarity tasks, which avoids the need to decompose natural high-level tasks in a complex sequence of sub-tasks. Following the Design Science Research methodology, three prototypes to support as well as to refine those tasks were iteratively designed, implemented, and evaluated involving an increasing number of educators in usability oriented studies. The resulting high-level and domain-oriented blended search/recommendation strategy, transparently replicates Google searches in specialized networks, and identifies similar resources with a QBE strategy. It makes use of a domain-oriented similarity metric based on shared schema.org/LRMI alignments to educational frameworks, and clusters results in expandable classes of comparable degree of similarity. The summative evaluation shows that educators appreciate this exploratory-oriented strategy because – balancing similarity and diversity – it supports their high-level tasks, such as lesson planning and personalization of education

Supporting the Discoverability of Open Educational Resources: on the Scent of a Hidden Treasury

Open Educational Resources (OERs), now available in large numbers, have a considerable potential to improve many aspects of society, yet one of the factors limiting this positive impact is the difficulty to discover them. This thesis investigates and proposes strategies to better support educators in discovering OERs. The literature suggests that the effectiveness of existing search systems, including for OER discovery, could be improved by supporting users, such as teachers, in carrying out more exploratory search activities closer to their existing methods of working. Hence, a preliminary taxonomy of OER-related search tasks was produced, based on an analysis of the literature, interpreted through Information Foraging Theory. This taxonomy was empirically evaluated to preliminarily identify a set of search tasks that involve finding other OERs similar to one that has already been identified, a process that is generally referred to as Query By Example (QBE). Following the Design Science Research methodology, three prototypes to support as well as to refine those tasks were iteratively designed, implemented, and evaluated involving an increasing number of educators in usability oriented studies. The resulting high-level and domain-oriented blended search/recommendation strategy transparently replicates Google searches in specialized networks, and identifies similar resources with a QBE strategy. It makes use of a domain-oriented similarity metric based on shared alignments to educational standards, and clusters results in expandable classes of comparable degrees of similarity. The summative evaluation shows that educators do appreciate this strategy because it is exploratory and – balancing similarity and diversity – it supports their high-level tasks, such as lesson planning and personalization of education. Finally, potential barriers and opportunities for the uptake of OER discovery tools were investigated in a structured interview study with experts from the OER field. Identified issues included how to work across multiple OER portals, variability in the use of metadata and how to align with the working practices of teachers. The findings of the thesis can be used to inform the research and development of methods and tools for OER discovery as well as their deployment to serve the needs of educators

The Power of Open: Benefits, Barriers, and Strategies for Integration of Open Educational Resources

Open Educational Resources (OER) are becoming a significant, mission-driven trend within educational literature. To help address rising costs, instructors and designers are looking to OER to effectively replace traditional instructional content, which requires more than just identify and replace. Drawing from 51 OER studies conducted in countries across the five continents, this systematic literature review explored the empirical themes evident in the current research on a global scale. This review found (1) discoverability, sustainability, and remixing are significant barriers that stand in the way of OER disrupting traditional textbook models; (2) there is no significant difference in learning outcomes when instructors incorporate OER; and (3) implementation of OER as instructional strategies is challenging but can be effective in supporting positive learning outcomes when properly designed. The paper concludes with a discussion of gaps in the literature, considerations for implementation and further directions for future research

Learning the Lessons of Openness

The Open Educational Resources (OER) movement has built up a record of experience and achievements since it was formed 10 years ago as an identifiable approach to sharing online learning materials. In its initial phase, much activity was driven by ideals and interest in finding new ways to release content, with less direct research and reflection on the process. It is now important to consider the impact of OER and the types of evidence that are being generated across initiatives, organisations and individuals. Drawing on the work of OLnet (http://olnet.org) in bringing people together through fellowships, research projects and supporting collective intelligence about OER, we discuss the key challenges facing the OER movement. We go on to consider these challenges in the context of another project, Bridge to Success (http://b2s.aacc.edu), identifying the services which can support open education in the future

Overview and Analysis of Practices with Open Educational Resources in Adult Education in Europe

OER4Adults aimed to provide an overview of Open Educational Practices in adult learning in Europe, identifying enablers and barriers to successful implementation of practices with OER. The project was conducted in 2012-2013 by a team from the Caledonian Academy, Glasgow Caledonian University, funded by The Institute for Prospective Technological Studies (IPTS). The project drew on data from four main sources: • OER4Adults inventory of over 150 OER initiatives relevant to adult learning in Europe • Responses from the leaders of 36 OER initiatives to a detailed SWOT survey • Responses from 89 lifelong learners and adult educators to a short poll • The Vision Papers on Open Education 2030: Lifelong Learning published by IPTS Interpretation was informed by interviews with OER and adult education experts, discussion at the IPTS Foresight Workshop on Open Education and Lifelong Learning 2030, and evaluation of the UKOER programme. Analysis revealed 6 tensions that drive developing practices around OER in adult learning as well 6 summary recommendations for the further development of such practices

When two worlds don’t collide: can social curation address the marginalisation of open educational practices and resources from outside academia?

A canyonesque gulf has long existed between open academia and many external subject communities. Since 2011, we have been developing and piloting the public open scholar role (Coughlan and Perryman 2012) - involving open academics discovering, sharing and discussing open educational resources (OER) with online communities outside formal education in order to help bridge this gulf. In 2013 we took the public open scholar into Facebook (Perryman and Coughlan, 2013) to reach an international audience of autism-focussed Facebook groups in India, Africa and Malaysia, with a combined membership of over 5000 people. Performing the public open scholar role within Facebook led to our learning from group members about new resources produced outside formal education, for example by voluntary sector organisations, government and professional bodies. These resources are surprisingly numerous and compare favourably with those from universities. Seeking to source more such resources we conducted a systematic large scale search of free online courses, recording not only the number of learning materials available but also how easy it was to find them. We found that provision from formal education, especially universities, dominates the returned results when searching for free online courses. Consequently, resources from outside formal education, while they exist, are difficult to find. Indeed, most aggregators and repositories proudly state that the free online courses they list are from 'Top Universities', appearing oblivious to provision from outside formal education. We extended our research to cover e-textbooks and found a similar situation, with content from formal education again dominating provision. On the basis of these findings we suggest that the prominence of university-provided content within search aggregators not only marginalises externally produced resources, relegating them to even more obscurity than has been the case thus far, but also marginalises the open educational practices that were involved in the production of these resources. We propose that the OER movement’s questions about ways of involving end-users as co-producers may be answered by looking to external communities and, accordingly, we should be supporting and learning from these communities. In addition, there is a need for further research into the open educational practices of external subject communities, who are clearly more than just passive consumers of resources and are involved in both producing and adapting OER. Our research has also led to our further developing the public open scholar role to include curation as a part of the process, on the basis of evidence indicating that online content curation has the potential to help increase the discoverability of resources and awareness of open educational practices from beyond academia. In particular, we suggest that ‘social curation’ ( Seitzinger, 2014) - which foregrounds sharing curated collections as a component of the curation process - has a key role in this regard. We suggest that further research in this area could be beneficial, for example in exploring the potential for librarians to become involved in curating OER from outside academia

Collaborative Authoring of Open Courseware with SlideWiki: A Case Study in Open Education

Producing or finding and reusing high-quality educational content online can be a laborious and costly process. With the open-source and open-access SlideWiki platform, the effort of producing and reusing highly-structured remixable educational content can be crowdsourced and therefore widely shared. SlideWiki employs crowdsourcing methods in order to support the open education community in authoring, sharing, reusing and remixing open courseware. This paper presents a case study of this platform carried out in the context of open education and informal learning and reports on the feedback received thus far from members of the open education community
