Introduction: The paper’s introduction contains a set of notes concerning high-quality preparation of pupils and students and doing best to achieve adequate efficiency related to the educational process, where pupils’ or students’ personality development and activation together with their key-competence and self-cultivation development, as well as preparation for the labour market, successful versatility plays a role of great importance. The pupils’ or the students’ capability to work with information included in the natural language test is considered to be of a great importance for their further professional or private life. Therefore, any school is responsible for the quality of education and teachers should work with adequate and up-to-date, high quality teaching and learning aids.
Purpose: The purpose of the study was to monitor and verify the didactic efficiency of the proposed chapters for the Economics textbook at a technical secondary school in Hlohovec, as well as to check the quality of the proposed textbook in relation to the outputs of the educational process.
Methods: The following methods and techniques related to the investigation of a developed Economics textbook have been applied: natural pedagogic experiment; questionnaire; cloze test; didactic test and statistical methods for data processing.
Conclusions: The research has shown that the created textbook for Economics is appropriate for students. We believe that introducing newly developed textbooks/teaching materials into the teaching process (despite modern types of media) may contribute to improving the quality and efficiency of the educational process.
