Effective creation of interactive educational objects for on-line teaching

Interactive educational objects, or interactive elements in short, are the cornerstones of interactive teaching. Their use distinguishes "real" on-line teaching, that is teaching that requires interaction of the consumer of education with the educational material in real time, from teaching that only offers the distribution of "electronic (university) textbooks".Recently, we have been involved in both individual and routine creation of interactive elements for hundreds of interactive educational materials.The paper focuses on the philosophy of using interactive elements in educational materials as well as didactical and pedagogical contexts and impacts. The core of the article focuses on explaining the possibilities of different types of interactive elements usage in on-line teaching as well as their advantages and limitations. The article also describes the technical processing of interactive elements in way, that enables their production in large quantities and excellent quality while keeping low costs.
