Abstract
The information technologies applications in various fields of human activity are developing exponentially now. The article considers possibility of using screencasting in a computer science course at a technical university. Screencast is a video that contains a record of actions performed on a computer with the author’s comments. The advantages and disadvantages of this technology in the learning process are considered. It is noted that the technology of on-screen video is distinguished by information richness and strong emotional effect on the student. The application of screencasting in computer science classes at the Tomsk Polytechnic University using the mathematical package MathCad, which has the means to solve all kinds of problems associated with symbolic operations, is presented. The motivation for this study is to increase the student learning process effectiveness. Therefore, the objectives of the study are: to study the possibility of screencasting in the student learning process organization, to study the possibility of using this technology during studying a computer science course, to find out how effectively this method allows to master knowledge in the relevant discipline. The results of study using this technology and the traditional method are analyzed. It is shown that the use of screencasting allows to improve the test results in comparison with the group trained by the traditional method.
Highlights
The term “screencast” was created by John Udell in 2004 [1]
In light of the reduction in classroom hours devoted to the study of mathematics, a practical course in computer science begins with the study of the MathCad system, which is considered by our teachers as a supporting course in mathematics [12]
The education material for the first group was presented in the form of videos in which the use of MathCad tools was demonstrated, in accordance with the purpose of the laboratory work
Summary
The term “screencast” was created by John Udell in 2004 [1]. He called screencast “software videos about software recorded with speech” [2]. The application area of screencasting is much wider than just the development of demonstration materials for the study of computer programs This technology is used in the educational process [3]. Screencasting is successfully used for creation of a wide variety of training materials related to various fields of knowledge [4,5,6,7] This technology fundamentally changes the interaction between teacher and student. If student missed a lesson, there is nothing to worry about, because with the help of a video clip he will be able to study a missed topic on his own [11] Another important point is that the studied material presented using screencasting technology, as a rule, is ordered, planned, holistic, aimed at clarifying the topic, since its development is based on comprehensive preliminary preparation of the studied material
