TLDR
This work presents a contextual access architecture for personalization and recommendation of interactive multimedia content captured in an instrumented instrumented environment that takes into account context information, user preferences and presentation constraints in order to personalize the access experience, tailoring it to users' needs.Abstract:
Multimedia capture and context awareness are two relevant subjects in ubiquitous computing research. While the former results in large amounts of digital media (e.g., video, audio, slides, text comments) being automatically produced, the latter offers the proper means to integrate and access such content. By merging the two concepts, users may benefit from tools that allow them to retrieve, view and interact with the captured media artifacts. In this paper, we present a contextual access architecture for personalization and recommendation of interactive multimedia content captured in an instrumented ed- ucational environment. Our approach takes into account context information, user preferences and presentation constraints in order to personalize the access experience, tailoring it to users' needs.read more

Formation assessment of the professional competences of electrical engineers specialists
Abstract: The article considers the actual problem of pedagogical diagnostics of the formation of professional competencies of engineering students. Based on a thorough analysis of the educational and professional program "Electrotechnics, electric power engineering and electromechanics" twelve professional competencies were identified, they were correlated with the program results defined in the state standard and possible diagnostic tools were proposed, such as tasks on virtual stands, tasks on physical stands, professional-focused tasks. Such an approach was due to the understanding that professional competencies are cross-curricular in nature, and the possession of them involves not only acquired knowledge, skills and abilities, but also the ability to use them in future professional activities, understanding its content and having the ability to overcome problems arising in production. A method of assessment of professional competencies is proposed, which is based on the principle of differentiation and foresees testing each specific competence using three diagnostic tools, which provided the identification of the level of the fundamental and practical knowledge, ability to work with equipment and solve unusual situations that may arise in production. The following methods were used in the study. Theoretical analysis and synthesis of research related to pedagogical diagnostics, works in which methods of information visualization are analyzed; design for the development of a program-designer "star of competencies" using the software package MATLAB. Empirical expert assessment to identify tools for diagnosing the formation of professional competencies common among teachers; diagnostics of formation of professional competences of students by means of testing, interrogation. The visual image of the "competence star" is offered, which allowed to solve a number of tasks: to provide ease and speed of perception of the learning outcome; informational content due to the simultaneous presentation of the results of the formation of twelve competencies and the ability to analyze each separately; to realize better the level of achievements according to the formation of the program results defined in the educational standard.
