“…On the next step of the method, the content of each element of the set of headers H is processed to search for lower-level semantic units in the form of key terms. First, a set of all possible candidate-terms is formed, their occurrence in the content is searched, the numerical value of their importance is determined using the method of disperse estimation, their number in the resulting set is limited using the method of limiting keyword density [15]. These operations result in elements of the set of key terms K and the corresponding relations:…”

The article considers the method that allows to calculate the estimation of knowledge level of educational materials by using indicators of semantic importance of key terms for adaptive selection of test tasks in testing. Each test task allows to purposefully check the level of knowledge of separate semantic units of educational materials -semantic terms (words, phrases). It is assumed that increasing the depth of learning of educational material semantic content has the effect of learning less semantically important units of educational materials. Semantic terms are related to the semantic structure of educational material in the form of rubricational system. Test tasks are related to fragments of educational material content, the knowledge level of which they test. In the process of testing, the level of knowledge of each of semantic structure elements of the educational material is consistently adaptively determined, and the final grade is calculated based on these results. As a result of adaptive selection of test tasks, their maximum possible diversity in the final set is reached, because following criteria are considered: test task has not been used yet, relevant fragment of educational content has not been checked, test tasks of corresponding type were used the least, the test task does not contain less important semantic units. The developed method of adaptive semantic testing of knowledge level of educational materials makes possible to use different algorithms for starting testing (regressive, progressive, medianic, etc.) and different algorithms for knowledge level estimation (average, absolute limit, etc.). Applied investigations of the effectiveness of the developed method in comparison with the traditional algorithm for selecting test tasks established, that testing speed increased an average of 20.53% faster test, and to determine the level of knowledge required the use of an average of 19.33% fewer test tasks.

Teaching Ukrainian as a foreign language requires a competent combination of traditional forms of learning and the possibilities of IT technologies. This study has been conducted to evaluate the effectiveness of IT technologies introduction in the educational process during the study of Ukrainian phraseology by foreign students. Authors conducted an experiment, which involved the introduction of IT technologies in the process of gradual study of phraseology at the lessons of Ukrainian as a foreign language during the academic year. 20 foreign students of the 3rd year participated in the experiment, from whom an experimental and control group of 10 students each was formed. Pre-and post-experimental tests to compare academic achievements, pre-and postexperimental surveys, informal interviews, observations of participants in the learning process were used as a means of data collection. The authors provided a system of tasks using Internet communications, computer presentations, online dictionaries, elements of the blended learning system for each stage of working with phraseological units. The obtained results confirmed the hypothesis: the use of IT technologies in the study of phraseologisms by foreign students increases their motivation for learning, and, as a consequence, improves learning performance. Indicators of academic achievement of the experimental group exceeded the starting level, while the control group noted a decrease in the indicators of academic achievement. Prospective directions for further research may be related to theoretical generalisations in the field of methodology of teaching Ukrainian as a foreign language, as well as to the development and implementation of modern complex methods using IT technologies.
