Abstract
The article deals with Gran software and the access to it through the remote desktop. The peculiarities of web-based remote desktop access and Gran software system for teaching mathematics at school are revealed. The paper also describes the application of open source software (Ulteo OVD) that allows users to remotely access their desktops and applications using one of the Desktop as a Service cloud components through a client device browser. The modes of using Ulteo OVD client software are described. Two servers (Application Server and Session Manager Server) have been organized to use Ulteo OVD by means of PROXMOX web-based virtual environment. The authors propose the way to use Ulteo OVD to access software installed on a remote server, in particular Gran software. The article also describes some examples of graphical problem solving using Gran1 that can be used in maths at school. The considered issues are quite complex and rather time-consuming without Gran1 software for graphical analysis of various tasks and approximate calculation of numerical measures of different objects (lengths of surfaces, areas of surfaces, volumes of bodies, probabilities of occurrence of different events, statistical analysis of observational data) of their solving. The range of tasks that can be solved with the use of the Gran software package, in particular Gran1 programme, is quite broad. By applying a creative approach, their analysis and solution can have a positive effect on the learners’ mental and cultural development. It is emphasized that the use of various technologies in educational process, as well as the selection of tasks and the content of training in general, should be pedagogically weighted, based on the harmonious combination of pedagogical heritage of the past and modern achievements of scientific and technological progress.
