“…It indicates the degree to which the service meets user anticipation, especially from the user's point of view to the valuation performance of the service, Figure-1 show that QoE is an extension to the QoS. The evolving in the network infrastructure and e-commerce environment making the Service providers concern great weight to quality control and are associated with improving the quality of the user experience as one of the main competition methods [5].…”

“…The quality of service (QoS) define the overall characteristics of a service such as communication that affect the satisfied of user's service needs [5].From video streaming point, QoS indicated to the capability of the network to transmit packet in the best way possible, QoS represents the networkcentric. However, the obvious question is how QoS control and measure the perception of user's service.…”

Technological development in the last years leads to increase the access speed in the internet networks that allow a huge number of users watching videos online. Video streaming impo rtant type in the real-t ime v ideo sessions and one of the most popular applications in networking systems. The Quality of Service (QoS) techniques give us indicate to the effect of mult imedia t raffic on the network performance, but this techniques do not reflect the user perception. Using QoS and Quality of Experience (QoE) together can give guarantee to the distribution of video content according to video content characteristics and the user experience. To measure the users' perception of the quality we use Quality of Experience (Qo E) metric. Here , in comp lete we display what the QoE and QoS mean and what the difference between them, list the techniques used to measured them ; then we d isplay a study of the literature on different tools and measurement methodologies that have been proposed to measure or predict the QoE of video streaming services .

“…In the last few years, QoE ("Quality of Experience", 2011) has emerged as a fully user-oriented approach which focuses on the social element, users' subjective expectation and evaluation of systems' delivery and performance (Kalliris, Dimoulas, Veglis, & Matsiola, 2011;Kist & Brodie, 2012;W. Wu et al, 2009;Zhang, Xu, & Cheng, 2011). Furthermore, videoconferencing-based educational systems provide tremendous convenience and flexibility for adult students, while bridging the distance between the teacher as a source of information and the students.…”

“…In the same context, different studies have already demonstrated QoE as a more holistic evaluation than mere narrowly focused end-user experience (Kalliris et al 2011;Molnar, Hava-Muntean, & Cristea, 2009;W. Wu et al, 2009;Zhang et al, 2011). Gong, Yang, Huang and Su (2009) have defined a QoE model that focused on the relationship between the technical and QoE parameters that consisted of five factors: availability, usability, integrality, retainability and instantaneousness.…”

Distance education learning environments provide tremendous convenience and flexibility, allowing busy, mobile adult learners to engage in education while coping with their limited resources in terms of time, energy and finances. Following a student-centered approach this study investigates adult students' subjective perceptions while using distance education systems based on a videoconferencing platform as Quality of Experience (QoE). Based on a literature review, sociological behavior and expectations, we have constructed a structural equation model (SEM) illustrating relations among different variables that can predict positive levels of adult students' QoE, thus providing guidelines for proper development. We have tested the model using a survey of 198 primary education school teachers involved in a videoconferencing-based learning program for teacher enhancement. Results show a good fit to the model developed. The analysis showed that adult students' QoE is directly influenced by appropriateness of teacher-student interaction and ease of participation, as well predicted by students' motivation to attend similar trainings. Additionally, we found that variances in technical quality did not directly influence their QoE from the learning sessions.

<span>The integration of computer games in the primary school program is a challenging task which requires changes in the pedagogical approach and teaching practices. Since it is important to understand students, this study follows student-centered approach while evaluating different variables in computer game enhanced classes, which impact the overall students’ Quality of Experience (QoE). We involved a total of 114 students in several primary schools in Macedonia which participated in traditional and game-based learning environment. Students’ feedback was collected through surveys and the data set was analyzed with a path analysis model that illustrates relationships between relevant variables which influence students’ QoE in classes enhanced with computer games. We found that students’ motivation mostly influenced students’ QoE, which was also determined by the increased effectiveness and simplified way of learning. The research results correlated students’ QoE and learning outcomes during integration of computer games in primary schools, which were altogether increased against the traditional environment.</span>
