The idea that one has to know some principles of Computer Science in order to be proficient in the use of "computers" in general, let alone in Education, seemed then to be very radical. While that paper was very popular among teachers in the field in Israel, its principal message was hard to understand, to accept and to implement. Yet, as a later analysis has shown, the idea of relying on Theoretical Informatics is a logical necessity for any significant employment of digital technologies in Education.
Our main concern has been the explication of this idea in a way that can be accpeted by teachers that are not inclined to become familiar with the theroetical aspects of the new Digital Technology. We even published a book (in Hebrew) for the purpose of teaching the basic concepts, principles and methods that we developed in Educational Informatics (in 2001). Here are listed also some of our papers on Educational Informatics the way we have developed it along these lines. They provide the arguments that prove the logical necessity of Educational Informatics as a theoretical application of Informatics to Education, and they describe and explain the methods we have developed for its applications and its teaching.
