The use of information and communication technologies when teaching students with hearing impairment at a technical university

Abstract

Introduction. The use of information and communication technologies (ICT) in education provides promising opportunities for individual learning. However, one can question the efficiency of using electronic resources for certain students, e.g. hearing-impaired students, if their special cognitive characteristics were not considered while designing these resources. The aim of the research presented in the publication is to develop a scientific basis and the methodology for the effective teaching of basic disciplines using various sources of information. Methodology and research methods. The presented research results were obtained using standard and adapted methods (‘10 words’ adapted technique, Schulte tables, standardized methods for studying reading skills), questionnaires, analysis of written works based on the developed criteria. A series of experiments involved students majoring in Engineering at Kalashnikov Izhevsk State Technical University: 98 students participated in experiments with the adapted "10 words" method and Schulte tables (19 of them were hearing impaired); for the analysis of writing skills, the works of 116 students were collected (27 of them-with hearing impairment); 12 students with hearing impairment took part in experiments on reading skills. Results. For short-term memory, the results turned out to be better when demonstrating words from the electronic board than from printed sources (students with health standard: electronic board – 7.24 words; printed source – 6.39; for deaf and hard of hearing students: 6.2 and 5.8 words respectively). Based on the results of the attentiveness test (adapted Schulte tables), this indicator is better when working with tables in paper form (Student's t-test: tcr=1.97 (p≤0.05), tcr=2.61(p≤0.01), temp = 2.3). For reading skills, research has shown that students did a better job with keyword and abstracting when working with printed text (tcr=2.07 (p≤0.05), tcr=2.82(p≤0.01), temp= 2.4). As for the monitoring of writing skills, for hearing impaired students, the main monitoring criterion is emotionality (expressiveness); some features of visual perception of the sentences arrangement are also noted. Scientific novelty. The analysis of the results of these experiments will allow us to clarify the features of comparing the cognitive skills dealing with the information perception from different media when teaching people with hearing impairment. Practical significance. The results obtained allowed us to conclude that in the learning process it is recommended to combine sources of information on different media.
