Classification of Mobile Customers Behavior and Usage Patterns using Self-Organizing Neural Networks  
By Rawan Ghnemat and Edward Jaser

Abstract

Mobile usage is witnessing a booming growth attributed to advances in smartphone technologies, the extremely high penetration rate and the availability of popular mobile applications. Telecommunication markets have been injecting huge investments to fulfil the sheer demand on wireless network and mobile services as a result. Such potentials highlights the importance of behavioral segmentation of mobile network users to target different sectors of customers with efficient marketing strategies and ensure customer retention in light of the intense competition. A major hurdle in applying this approach is the number of dimensions underlying customer preferences which makes it hard to visualize similarities among customers and formulate behavioral segments correctly and efficiently. In this paper, we use self-organizing maps, to detect different usage patterns of mobile users. The proposed system is tested using a large sample of customers’ data provided by major mobile operator in Jordan. The study detected different behavioural segments in this market and highlights the role of data users in modern mobile markets. In this context, we give detailed analysis of our results on user behavioral segmentation.

Success Factors of Online Learning Videos

Safak Korkut, Rolf Dornberger, Prajakta Diwanji, Bindu Puthur Simon and Michael Maerki

Abstract
Videos have emerged as a dominant medium for educational purposes in many Massive Open Online Course (MOOC) platforms. Online learning videos are visual components of the online learning platforms. They are particularly interesting for students who are visual learners and who learn best by watching the short format engaging videos rather than by just reading or listening to course materials. The paper focuses on the categorization of factors that are responsible for the success/popularity of online learning videos. The research is based on the literature review and video observations of the MOOC platforms, in particular of the Khan Academy and Coursera. In this paper, we propose a tabular and a spider graph as a condensed overview of categories that should commonly be utilized by the online learning video production to make them successful.

Organizing, performing and presenting scientific work in engineering education with the help of mobile devices

Dominik May and Philipp Ossenberg

Abstract
The meaningful use of mobile devices in higher education learning contexts is still underrepresented at German universities. Even if these “new” technologies open up totally new teaching and learning experiences the current use is strongly dominated by simple technology provision. With a special course—designed for engineering students—the authors want to change this and go more into the direction of meaningful interaction and collaboration with the help of mobile devices throughout the learning process. The course is developed to give the students the opportunity to use tablet PCs in context of their studies and simultaneously to improve their ability in the field of scientific working processes. Making use of the online tool Evernote supported this aim. This tool allows users to work out and share digital notebooks and with this to organize as well as document a working process. In this case it was used to support a scientific research process from the beginning to the end. As Evernote can be used with an mobile app it easily can be used on tablet PCs. Hence, it supports the course idea of using mobile devices in perfect way. The course itself is divided into four face-to-face meetings and three working phases. By taking part in the course the students go through their own research project with explicit steps—from having a new idea for research to the results’ presentation. The meetings are mainly used in order to introduce tools or techniques for research processes. During the working phases the students do their research, create presentations, a poster, and a scientific report. Based on the internal course evaluation and the students’ feedback we observed, that the combination of tablet PCs with the Evernote software is a good opportunity to show how mobile devices can be meaningfully integrated into higher engineering education.
