Barriers in teaching are defined as all nuisances between the factors of the teaching process. Nuisances hamper the teaching process and affect the quality of educational communication and learning outcomes. The information won't become a part of student's knowledge, because he/she can't imagine it and understand it. Overcoming communicational barriers is everyone's need and obligation, this particularly applies to the people who are responsible for establishing the effective communication system. Depending on the criteria, barriers are classified as psychological, linguistic, educational, social, economic, technical and other barriers.
Teaching in general, and the teaching of computer science can be organized and therefore studied in terms of cybernetic didactic theory, in other words, system's theory and communication models. In the teaching of Computer Science, educational barriers are in the form of complex, too extensive and outdated textbooks, as well as unavailable actual technical literature. The conclusions of the paper are derived from the research conducted on students from high and technical schools in Vojvodina. The sample includes high schools in several towns, while the pilot study additionally includes elementary schools. As independent appraisers, students of the University of Novi Sad give their opinion about educational barriers in high schools.
In computer science teaching, several types of barriers were detected by students' evaluations and assessments based on interviewing techniques. The detected language barriers have low intensity, they permeate all other barriers: educational, psychological, technical, ergonomic, socioeconomic, and they vary depending on the demographic characteristics of the respondents. This paper points to the language barriers in teaching computer science, and also in IT education through systems theory and communication processes.
Data were analyzed using statistical methods. For determining variables' interrelation, the multiple-regression factor analyses by Gutman-Kaiser criterion was applied.
