Information and communications technologies today are used in virtually any university course when students prepare their papers. ICT is also needed after people are graduated from university and enter the job market. This author is an instructor in the field of informatics related to health care and social sciences at the Riga Stradins University. In practice, he has found that after completing informatics courses (IC) at the university level, students and practicing specialists at various levels find it hard to decide on what data processing method to use in order to interpret extracted results in the relevant area of specialisation. There are various data processing methods in the literature, presented individually and without adequate linkages. The author has found in practice that when such assignments are handled, there is closer linkage among data processing methods than the literature would suggest. In this article, the authors deal with the following issues: (1) how assignments given during informatics courses at the university level can be integrated with the relevant area of specialisation by making use of professional standards, guidebooks to studies in other courses, descriptions and scholarly publications so as to help students and practicing specialists to take decisions on data processing methods, their use, and the interpretation of their results; (2) how to ensure that educational data related to the area of specialisation are obtained on the basis of statistics in scholarly publications; (3) what kind of content is to be used for students of health care and the social sciences; (4) how to choose methods to resolve data processing issues; and (5) what are the recommended principles for evaluating the knowledge, skills and talents of students? The views that are presented in this paper are those of the authors or of other authors.
