The principal objective of the document on the further development in the Czechoslovak educational system is a gradual creation of conditions for providing complete secondary education to a majority of the young generation, and, in the long run, to everyone. The implementation of this objective in theoretical elaboration as well as in practical realization is centred on the sphere of secondary schools. The article goes on to characterise the position of secondary schools in the newly conceived educational system. Emphasis is laid especially on the elaboration of a new content of the educational system as a whole and thus also of secondary schools. The political document points out the socio-political objectives in education. The implementation of these objectives in the next stage of their realisation is primarily the concern of pedagogical science and research. The program of this work is contained in a comprehensive departmental plan of pedagogical research and in the State research plan. The conception of the departmental plan proceeds from the principle that the educational system forms a logically structured whole and in solving the problems of secondary schools attention is paid primarily to tasks common to all types of secondary schools and subsequently to special questions concerning each type of secondary school separately. The author then gives the characteristics of six thematic groups of problems common to all secondary schools, and outlines programmes for scientific and research work in the spheres concerning gymnasia (senior high schools), secondary vocational schools and secondary vocational training centres. A prerequisite for the realisation of the programmes is an inter-disciplinary conception of scientific and research work, participation of all scientific and research institutions including universities, and the use of the extensive store of theoretical knowledge and practical experience of the Soviet pedagogical science and educational practice as well as that of other Socialist states.
