Hence, the potential use of this medium for education needs exploration. This study presents Turkish higher education students' current practices and perceptions towards social media, and its potential use for learning in higher education. An online survey was administered to undergraduate students in order to discover their perceptions, awareness and concerns and to investigate their current tendencies, beliefs and opinions regarding social media use and education amalgamation

The e-learning industry is growing and offering new opportunities for both formal and informal learning. Open Educational Resources (OER) movement has gained considerable attention recently as an attempt to provide digital materials that can be used, and repurposed for teaching and learning. OER are becoming very popular learning materials including full courses, textbooks, modules, syllabi, lectures, homework assignments that are freely available online for everyone to use. Today, more higher education institutions are introducing OER and more alternative options for learning available such as Massive Open Online Courses (MOOCs) which might be considered as repositories of open access content. There is a significant need for colleges and universities to examine and understand the disruptive potential of new educational technologies such as MOOCs. This paper will dis...

This is a new step in the evolution of the Web of Things and of adaptive web-based systems. The current proposals for the Web of Things focus on the augmentation of the physical objects in order to provide enhanced services. However, in our view, the Web of Things can also be a means to make physical objects accessible or more usable for people with special needs by exploiting adaptive and semantic techniques. The architecture presented in the paper describes the specific modules and components at the basis of this approach.

In developing countries, social media not only satisfies personal communication needs but also tends to compete with mainstream media for news and play a significant role in social movements. Hence potential use of this mounting medium for education needs to be explored. In this study, a social media and education survey has been prepared in order to measure perceptions, awareness and concerns of students and educators coming from different generations on the topic of social media and its use in education. Such a study is crucial to materialize different policies and strategies for enhancing education with this popular and freely available technology. Students' and faculty members' perceptions, expectations and willingness about the educational use of social media are analyzed and different generations are compared. Results of this study could shed light for developing various strategies for integration of social media into Higher Education in developing countries where the difference between generations is typically felt larger.

In order to engineer Web applications which operate on microblogging data, there is a need for appropriate filtering techniques to identify messages. In this paper, we focus on detecting Twitter messages (tweets) that report on social events. We introduce a filtering pipeline that exploits textual features and n-grams to classify messages into event related and non-event related tweets. We analyze the impact of preprocessing techniques, achieving accuracies higher than 80%. Further, we present a strategy to automate labeling of training data, since our proposed filtering pipeline requires training data. When testing on our dataset, this semi-automated method achieves an accuracy of 79% and results comparable to the manual labeling approach.

The approach is primarily based on connecting and sharing data about accessibility requirements and real-world environment data. The approach is also founded on annotating physical objects, and adapting the interaction with the virtual side of cyber-physical objects in order to make physical objects accessible in a smart environment via smart devices. We define and build our model as an extension of previous research results in order to facilitate interaction with everyday objects and promote quality of life for those with special needs.

In the last few years, Twitter has become a powerful tool for publishing and discussing information. Yet, content exploration in Twitter requires substantial efforts and users often have to scan information streams by hand. In this paper, we approach this problem by means of faceted search. We propose strategies for inferring facets and facet values on Twitter by enriching the semantics of individual Twitter messages and present different methods, including personalized and context-adaptive methods, for making faceted search on Twitter more effective. We conduct a preliminary analysis that shows that semantic enrichment of tweets is essential for faceted search on Twitter and that there is essential need for adaptive faceted search on Twitter. Furthermore, we propose an evaluation methodology that allows us to automatically evaluate the quality of adaptive faceted search on Twitter without requiring expensive user studies.

Starting from a survey about current usage of social media in education and language teaching, the paper describes the extension of the L-Max Ontology to support teachers in building learning activities using Twitter, in relation to specific competences to be developed, specific learning goals and contextual constraints. To test the extended version of the recommender we performed a mockup evaluation based on the L-Max Ontology.

The learner's question can be made through vocal interaction or typed text and the answer is the generation of a personalized learning path. This takes into account the focus and type of the question and some personal features of the learner extracted both from the question and prosodic features, in case of vocal questions. The response is a learning path that preserves the precedence of the prerequisite relations and contains all the relevant concepts for answering the user's question. The main contribution of the paper is to investigate the possibility to exploit educational concept maps in a Q/A interactive learning system.

The workshop is focused on two main topics. On the one hand, we are interested in proactive user interfaces that support the user in ubiquitous contexts. This includes applications that can be provided as a service and can be used on any mobile device, with no need for installation or software updates; personalized user interfaces that track the user's progress, adapt to her/his needs and prompt her/him without being disruptive or inconvenient and provide analytics and predictive instruments; smart and personalized information services to explore, search, interact, share, practice and discover qualitative content that fits the user's diverse and changing needs; approaches that are focused on understanding and representing content, users, devices and situations where interaction happens, with special focus on semantics.

One of the major challenges that need to be accepted on the way is the development of mechanisms for student model integration. In this paper we propose an approach for aligning overlay models of students’ knowledge collected by different educational tools relying on different domain representations. The approach is based on common protocols for evidence communication and manual mapping of underlying domain models. This approach has been applied for integration of two existing educational systems in the framework of undergraduate Java course.

Therefore, understanding why and how educators use Web 2.0 is a necessary step towards promoting their effective use in teaching and learning. This study draws upon the uses and gratifications perspective to explore faculty members’ uses of Web 2.0 tools in instructional processes in an international higher education context. We gathered data from 15 faculty members via semistructured interviews as part of a phenomenological study design applying maximum variation sampling. We analyzed the data using content analysis. The results indicated that the faculty members were selective in their use of Web 2.0 tools and utilized a variety of Web 2.0 tools to gratify their cognitive, affective, social integrative and personal integrative needs in relation to instructional processes.
