Twenty Years of Edtech

An opinion often cited among educational technology (edtech) professionals is that theirs is a fast-changing field. This statement is sometimes used as a motivation (or veiled threat) to senior managers to embrace edtech because if they miss out now, it’ll be too late to catch up. However, amid this breathless attempt to keep abreast of new developments, the edtech field is remarkably poor at recording its own history or reflecting critically on its development. When Audrey Watters recently put out a request for recommended books on the history of educational technology, I couldn’t come up with any beyond the handful she already had listed. There are edtech books that often start with a historical chapter to set the current work in context, and there are edtech books that are now part of history, but there are very few edtech books dealing specifically with the field’s history. Maybe this reflects a lack of interest, as there has always been something of a year-zero mentality in the field. Edtech is also an area to which people come from other disciplines, so there is no shared set of concepts or history. This can be liberating but also infuriating. I’m sure I was not alone in emitting the occasional sigh when during the MOOC rush of 2012, so many “new” discoveries about online learning were reported—discoveries that were already tired concepts in the edtech field

Developing sustainable business models for institutions’ provision of open educational resources: Learning from OpenLearn users’ motivations and experiences

Universities across the globe have, for some time, been exploring the possibilities for achieving public benefit and generating business and visibility through releasing and sharing open educational resources (OER). Many have written about the need to develop sustainable and profitable business models around the production and release of OER. Downes (2006), for example, has questioned the financial sustainability of OER production at scale. Many of the proposed business models focus on OER’s value in generating revenue and detractors of OER have questioned whether they are in competition with formal education. This paper reports on a study intended to broaden the conversation about OER business models to consider the motivations and experiences of OER users as the basis for making a better informed decision about whether OER and formal learning are competitive or complementary with each other. The study focused on OpenLearn - the Open University’s (OU) web-based platform for OER, which hosts hundreds of online courses and videos and is accessed by over 3,000,000 users a year. A large scale survey and follow-up interviews with OpenLearn users worldwide revealed that university provided OER can offer learners a bridge to formal education, allowing them to try out a subject before registering on a formal course and to build confidence in their abilities as learners. In addition, it was found that using OER during formal paid-for study can improve learners’ performance and self-reliance, leading to increased retention and satisfaction with the learning experience

Open educational resources for all? Comparing user motivations and characteristics across The Open University’s iTunes U channel and OpenLearn platform.

With the rise in access to mobile multimedia devices, educational institutions have exploited the iTunes U platform as an additional channel to provide free educational resources with the aim of profile-raising and breaking down barriers to education. For those prepared to invest in content preparation, it is possible to produce interactive, portable material that can be made available globally. Commentators have questioned both the financial implications for platform-specific content production, and the availability of devices for learners to access it (Osborne, 2012). The Open University (OU) makes its free educational resources available on iTunes U and via its web-based open educational resources (OER) platform, OpenLearn. The OU’s OER on iTunes U reached the 60 million download mark in 2013; its OpenLearn platform boasts 27 million unique visitors since 2006. This paper reports the results of a large-scale study of users of the OU’s iTunes U channel and OpenLearn platform. A survey of several thousand users revealed key differences in demographics between those accessing OER via the web and via iTunes U. In addition, the data allowed comparison between three groups: formal learners, informal learners and educators. The study raises questions about whether university-provided OER meet the needs of users and makes recommendations for how content can be modified to suit their needs. As the publishing of OER becomes core to business, we reflect on reasons why understanding users’ motivations and demographics is vital, allowing for needs-led resource provision and content that is adapted to best achieve learner satisfaction, and to deliver institutions’ social mission

MOOC Phenomenon: Building An Effective And Sustainable Program

This qualitative case study examines critical processes of building an effective MOOC in the community college environment in support of workforce development education for those who are interested in exploring different careers or to improve upon existing skill sets and development/remedial education for incoming students. Five participants from community colleges were selected to participate in this study. They were identified as a purposive sample of community colleges that offer MOOCs and use different learning management systems that support MOOCs. Themes that emerged from interviews were: unanticipated global enrollment in MOOCs designed for local and regional audiences, challenges of designing and implementing MOOCs, and different decision making models these institutions used when deciding to offer a MOOC. This research data further affirms Thomas Friedman’s (2006) idea of a flat world where technology is supporting and allowing global education for students in the United States to be able to learn alongside students from various cultures and regions. However, this research also identifies a critical need for community college leaders to collaborate with faculty throughout the development process, to recognize decision-making approaches, and to provide the necessary funding and resources to support active outreach by instructors to students who are taking MOOCs so they can provide continuous learning and necessary mentorship

Integrating knowledge tracing and item response theory: A tale of two frameworks

Traditionally, the assessment and learning science commu-nities rely on different paradigms to model student performance. The assessment community uses Item Response Theory which allows modeling different student abilities and problem difficulties, while the learning science community uses Knowledge Tracing, which captures skill acquisition. These two paradigms are complementary - IRT cannot be used to model student learning, while Knowledge Tracing assumes all students and problems are the same. Recently, two highly related models based on a principled synthesis of IRT and Knowledge Tracing were introduced. However, these two models were evaluated on different data sets, using different evaluation metrics and with different ways of splitting the data into training and testing sets. In this paper we reconcile the models' results by presenting a unified view of the two models, and by evaluating the models under a common evaluation metric. We find that both models are equivalent and only differ in their training procedure. Our results show that the combined IRT and Knowledge Tracing models offer the best of assessment and learning sciences - high prediction accuracy like the IRT model, and the ability to model student learning like Knowledge Tracing

How to design for persistence and retention in MOOCs?

Design of educational interventions is typically carried out following a design cycle involving phases of investigation, conceptualization, prototyping, implementation, execution and evaluation. This cycle can be applied at different levels of granularity e.g. learning activity, module, course or programme. In this paper we consider an aspect of learner behavior that can be critical to the success of many MOOCs i.e. their persistence to study, and the related theme of learner retention. We reflect on the impact that consideration of these can have on design decisions at different stages in the design cycle with the aim of en-hancing MOOC design in relation to learner persistence and retention, with particular attention to the European context

Characterizing Algorithmic Performance in Machine Learning for Education

The integration of artificial intelligence (AI) in educational systems has revolutionized the field of education, offering numerous benefits such as personalized learning, intelligent tutoring, and data-driven insights. However, alongside this progress, concerns have arisen about potential algorithmic disparities and performance issues in AI applications for education. This doctoral thesis addresses these concerns and aims to foster the development of AI in educational contexts that emphasize performance analysis. The thesis begins by investigating the challenges and needs of the educational community in integrating responsible practices into AI-based educational systems. Through surveys and interviews with experts in the field, real-world needs and common areas for developing more responsible AI in education are identified. According to our findings, further research delves into the analysis of student behavior in both synchronous and asynchronous learning environments. By examining patterns of student engagement and predicting student success, the thesis uncovers potential performance issues (e.g., unknown unknowns: the model is really confident of its predictions but actually wrong), emphasizing the need for nuanced approaches that consider hidden factors impacting students’ learning outcomes. By providing an integrated view of the performance analyses conducted in different learning environments, the thesis offers a comprehensive understanding of the challenges and opportunities in developing responsible AI applications for education. Ultimately, this doctoral thesis contributes to the advancement of responsible AI in education, offering insights into the complexities of algorithmic disparities and their implications. The research work presented herein serves as a guiding framework for designing and deploying AI enabled educational systems that prioritize responsibility, and improved learning experiences
