Mobile-based Assessment (MBA) is an emerging field in the wider context of mobile learning research that has the potential to provide new opportunities for assessment.
However, successful implementation of MBA depends on user acceptance. While there is a considerable number of studies investigating mobile learning acceptance, no research exists that investigates the driving factors that influence intention to use mobile technologies for assessment purposes. Moreover, the motivational aspects of Mobile-based Assessment have not been fully explored. A comprehensive theoretical MBA framework, based on a solid theoretical background is needed to addresses the motivational dimensions of MBA.
This thesis is aiming at introducing analytical models about the acceptance of Mobile-Based Assessment from students‟ and teachers‟ perspectives as well. The thesis also suggests a comprehensive framework regarding motivation issues in Mobile-Based Assessment.Digital Library

Computerized self-assessment test systems can be an integral part of any e-learning system. Moreover, preparation tests through computerized self-assessment test systems, to help students before final exams, can be essential to any educational or learning process. Although lack of emotional recognition and emotional feedback capabilities of traditional tools of e-learning has been acknowledged as one major limitation in the recent decade, there have been no previous efforts to incorporate affective handling capabilities into self-assessment test systems.
This Ph.D. thesis is a first step towards this direction. In the context of this Ph.D. affect recognition and affective feedback methods were developed and evaluated for use during a computerized self-assessment test. The main contributions and conclusions of this Ph.D. are summarized in the following paragraphs:

In this PhD thesis we develop a number of decision analysis models for evaluating Information and Communication Technology (ICT) investments in the joint presence of uncertainty and competition. The target is to analyze investments risks, goals and constrains, estimate the optimum deployment strategy and finally evaluate the overall ICT business. Viewing ICT investments as real options (ROs), we model flexibility of implementing ICT business and combine them with various decision analysis techniques, such as game theory (GT), goal programming (GP), fuzzy logic (FL), analytic hierarchy process (ΑΗΡ) and SWOT analysis, for modelling specific ICT business characteristics in a holistic decision analysis perspective.
It is the first time in the literature where the aforementioned techniques are integrated for modeling the specific ICT business characteristics in a common decision analysis framework. Analytically, the existing ROs models are strictly quantitative, while ICT investments experience tangible and intangible factors and the latter can be mainly treated by qualitative analysis. Moreover, ROs analysis in itself brings to the "surface" a number of factors that cannot be quantified, at least easily, by existing ROs models and methodologies. In this work, we enhance the quantitative analysis of the ROs introducing further qualitative option thinking. Our work suggests the management and business analysts, which adopt ROs, to recognize qualitatively the factors affecting the investment value and treat them in a ROs perspective. The results from our models may change the conclusions extracted by the typical ROs approach given by the literature. The ability to hold the option and delay the investment depends on the balance between a large number of criteria, which some of them can be treated qualitatively while some others quantitatively. The results of the thesis prove that the combination of quantitative and qualitative analysis, under a multicriteria perspective, could provide different conclusion for an ICT business concerning its optimum deployment strategy and its overall performance comparing to single quantitative analysis. Finally, we apply the proposed models and methodologies in real case studies from broadband networks and services, e-learning and firms' reorganization business fields, showing how they can be formulated and solved. The cases analyzed prove the usefulness and efficiency of the proposed models and methodologies. Digital Library
