First, a description of the Evaluation Framework for Impact Measurement will be provided, followed by a brief overview of the IDEAL Reference Model. Finally, an example for the implementation of the Evaluation Framework for Impact Measurement within the ARISTOTELE project is presented.

Nella prima parte, si illustreranno i diversi tipi di OER, incluse le definizioni e le tipologie, in prospettiva di un futuro tipo di OER che le integri e comprenda tutte. Nella seconda parte si evidenzieranno i benefici apportati all'educazione dalle OER come argomenti a favore della loro applicazione pratica e adattamento. Inoltre, l'articolo distinguerà tra le diverse prospettive di utilizzo per dimostrare come le OER possono essere adoperate nella pratica. Verranno presentate le esperienze di utilizzo delle OER nel campo dell'inclusione scolastica all'interno del progetto EBE-EUSMOSI. Verranno infine presentate le sfide e le opportunità future per un ampliamento dell'uso e dell' impatto delle OER.

This paper intends to explore the promises and pitfalls of the Generative Pre-trained Transformer (GPT) AI and potentially future technologies by adopting a speculative methodology. Speculative future narratives with a specific focus on educational contexts are provided in an attempt to identify emerging themes and discuss their implications for education in the 21st century. Affordances of (using) AI in Education (AIEd) and possible adverse effects are identified and discussed which emerge from the narratives. It is argued that now is the best of times to define human vs AI contribution to education because AI can accomplish more and more educational activities that used to be the prerogative of human educators. Therefore, it is imperative to rethink the respective roles of technology and human educators in education with a future-oriented mindset.

The main research question was “How can the quality criteria for MOOCs identified in the analysed studies from the systematic literature review be best organised in a categorisation scheme?” The systematic literature review was conducted using the PRISMA procedures. After conducting the screening and eligibility analysis according the pre-defined criteria, 103 studies were finally selected. The analysis was done in iterative cycles for continuous improvements of the assignments and clustering of the quality criteria. The final version was validated in consensus through the categorisation and assignment of all 103 studies in a consistent way to four dimensions (pedagogical, organisational, technological, and social) and their sub-categories. This quality framework can be re-used in future MOOC research and the discussion of the analysed studies provides a curren...

First, the dimensions of Open Education are differentiated. Then the dimensions of holistic quality development are transferred to Open Education and discussed for the design of MOOCs leading to recommendations for personalization. A new quality indicator for evaluating the quality of MOOCs is introduced: It is proposed not to measure the traditional drop-out rates but the completion of individual goals and intentions by the MOOC learner. It is concluded that Open Education and MOOCs have got the potential for the next revolution in learning experiences.

The call received 59 proposals from nine countries, 39 papers were accepted to the virtual workshop and 26 full papers were finally selected to be published in the proceedings. The workshop illustrated a fast-developing scenario in which the epidemic emergency accelerated the dissemination and consolidation of online learning in higher education. A specific focus of the workshop can be identified as students’ learning experience, with studies on tutoring and active learning approaches, personalized solutions supported by data analysis, virtual reality and an in-depth analysis of human–computer interactions.

Also, Massive Open Online Courses (MOOCs) are recognized as a good strategy to enhance engineering education. Nevertheless, MOOCs have two main weaknesses: first, lack of addressing personal goals; and second, low completion rates in comparison to the number of registrations to the MOOCs. To improve learning experiences in MOOCs and to strengthen self-regulated personalized learning we propose the application of gamification in MOOCs. Our assumption is that MOOC learners will better succeed in achieving their goals if they can individually personalize and plan their learning paths through gamification. This assumption is based on the implementation intention theory which claims that people who foster their goal intentions with implementation intentions are comparatively more successful in their personal goal achievements. Based on a preliminary literature review this article presents and arguments on our research idea on how to apply gamification to enhance MOOC users' goal achievement. Besides, it introduces a new perspective on MOOC completion rates based on the user intention and a new way of measuring it via the Personal Goal Achievement Ratio (PGAR) and the Overall Goal Achievement Ratio (OGAR).

This article discusses whether MOOCs should be considered as OER. Open Education and OER can be treated as two strands with different historical roots even though, in theory, OER are an aspect of Open Education. Different OER definitions and typologies are analyzed in relation to their dimensions and categorizations. Furthermore, the four conditions and two original categories of MOOCs are discussed, leading to a debate on their quality. It turns out that there are two perspectives on MOOCs: from an OER perspective, MOOCs as a product can be called OER. From an Open Education perspective, MOOCs are going beyond OER as enablers of Open Education and are understood as an innovative way of changing education. These perspectives are reflected by the OpenEd Quality Framework. The short answer to our leading question is: sometimes, and it depends ...

It provides a holistic framework for pupil-centered learning processes developed by an international research consortium. It is based on the findings from a literature review, three online survey and semi-structured interviews with participation of teachers (n=211), headmasters (n=21) and learners (n=337) from more than ten countries. The research results are used for a teacher training programme and an online course that the international research consortium is currently designing and implementing. This article presents the holistic pedagogical model Learn STEM as the first outcome of the Mixed Methods Research conducted by the international research consortium.

A systematic literature review confirms the hypothesis that a holistic quality framework for Open Education does not exist. For its development, a brief history and definition of Open Education are provided first. It is argued that Open Education improves learning quality through the facilitation of innovative learning designs and processes. Therefore, sources of learning quality and dimensions of quality development are discussed. To support the improvement of the learning quality and design of Open Education, the Reference Process Model of ISO/IEC 40180 (former ISO/IEC 19796-1) is introduced and modified for Open Education. Adapting the three quality dimensions and applying the macro, meso, and micro levels, the OpenEd Quality Framework is developed. This framework combines and integr...

Assigning a grade of relative distance to represent the level of similarity between the related pairs of classifiers could correct this situation, which has been considered as an oversimplification of the psychological account of the real-world relations. The paper aims to discuss these issues. Design/methodology/approach The evaluation followed an end-user perspective. In order to obtain a consistent data set of specialization distances, a group of 21 persons was asked to assign values to a set of relations from a selection of terms from the AGROVOC thesaurus. Then two sets of representations of the relations between the terms were built, one according to the calculated concept of specialization weights and the other one following the original order of the thesaurus. In...
