Enabling Information Access in Virtual Learning Environment: The Case of Data Science Minor
In this paper, we present our current research regarding information interaction strategies of students of minor specialization in Data Science. We employed an online platform, consisted of a third-party and our software, to provide students with means of learning and analyse their learning activity. We developed several indicators to estimate their activity: coding activity, friends network size, and Q&A activity. We show that high-achieving and low-achieving students use resources in different ways, with substantial inequality in resource access/use. Based on the research, we propose two features that supposedly would provoke students to participate in a Q&A activity decreasing inequality in the use of these resources.
Low-cost gaze tracking systems are in great demand due to their wide range of application. Commonly, extra devices are needed (for instance, head mounted cameras); however, in this investigation gaze tracking is performed in real-time based on the video stream from an infrared video camera. A comparative analysis of the existing analogues was executed and the main features of gaze tracking systems were highlighted and prioritized. These features are price, tracking accuracy, angle error, flexibility, and usability.
A methodology was developed which allows to calculate a gaze direction vector according to the relative position of eye center and corneal reflection from an infrared diode. The centers of an eye and reflection are estimated using the vector field of image gradients and additional weighting. CUDA technology is used to accelerate the developed algorithms.
The main advantage of the developed algorithm is the ability to detect and continuously track pupils’ centers, regardless of the head position, which significantly extends the scope of the gaze tracking system under consideration.
Propaedeutics of engineering culture in the school should not be limited by familiarity with the school robotics. It is necessary to the development of other components of the engineering culture, such as TRIZ, system analysis, project management, and others. The possible content of these components and the ability of their studying in the "Permian version" of a propaedeutic course of computer science ("TRIZformatics") and contest "TRIZformashka" are discussed.
Usually marketization is associated with the commercialization as the desire for recovery of the profit. This means replacing the educational functions to the provision of services, with all the unfortunate consequences. However, such an approach is superficial and emotional. The orientation of higher education on the client is very appropriate. Moreover, it is able to put a lot into place.
Modern teenagers immerse in the social networking sites is a debatable issue among parents, psychologists and educators. Researches describing the phenomenon of social graphs and their attractiveness are rather contradictory. Based on the fact that this new technology has become the most demanded among young people we can assume that social networks available adequate puberty period are. Thus puts forward the hypothesis that through the study of social networks as a new resource meets the needs of puberty is possible to construct the present demands and leading activity of the modern teenager. Special attention is paid to the study of developmental potential of social networks for education and socialization of adolescents.
Articles and presentations of Russian researchers, dedicating to different aspects of the United States foreign and domestic policy, actual issues of American historiography, problems of history of literature, linguistics and pedagogy are include in the book. For scholars, teachers, students, for everyone who is interested in the problems of American studies.
