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.
This study aims to analyse the tenure of head coaches in college women’s soccer in the United States and puts the focus on the influence of race and gender. The analysis includes individual characteristics of coaches (educational and professional background), team performance, institutional characteristics, and geographical differences (at the state level) from 1977 until 2015. The main results show that African American coaches and women have a significantly shorter tenure in these college institutions. Other factors related to the background of coaches and the characteristics of institutions also play a significant role. The findings are relevant for coaches from minority groups and athletic departments, who are interested in equity in sport. Future research may use an alternative approach to investigate the causes of tenure disparity in college women’s soccer.
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.
Software engineering education (SEE) process simulates the main professional software lifecycle processes such as analysis, design, construction and maintenance (see SWEBoK, ITIL, etc.). The necessity of meeting both educational needs and requirements from industry explains that using Supported Collaborative Learning (CSCL) techniques in software engineering (SE) should be based on professional tools or on similar to them. The main purpose of this work is to fill the gap between the SEE needs and the current trends in CSCL development. We generalize world experience and suggest the framework of using industry approved methods and tools. We compare CSCL tools and the other collaborative services; analyze the teaching experience of several SE courses supported by different collaborative methods and collaborative web-services. Special attention is paid to formative feedback implementation. Following achieved result we suppose that using best practices from SE will enrich CSCL methodology and tools not only for SE field, but also for other areas of knowledge.
