MatCos 3.0

In this chapter, the authors present MatCos 3.0 software aimed at the primary school. First, the pedagogical-didactic and training bases on which the construction of the software is based will be exposed, albeit briefly. All the buttons on the user interface and all the axiomatic and genetic commands available are presented. The method used is a direct presentation aimed at technical use. Some pedagogical-educational observations will be given. Numerous examples and screenshots will be given. The commands will not be displayed in strictly alphabetical order, but a more logical and consequential line has been preferred. At the end of the chapter, the alphabetical list of all the commands available in the programming environment will be shown.

Onomastics of the village Velika Kruševica near Rekovac

The paper presents the onomastics recorded in Levač village Velika Kruševica which is situated in the Levač municipality. We have registered toponyms, personal and family nicknames, personal names and surnames of all the residents who have been in the village during our visit (some have been working in the fields). A short analysis of lexical and semantic units has been done as well as the classification of the registered onyms. Integral part of the paper is also a dictionary with an alphabetical list of the recorded onyms.
