This text of Walther Lietzmann could be transferred without any change to the situation of teaching informatics (and other technologies). But by a more intense knowledge you may adhere to the opinion that things here went just the opposite way: By the beginning of computer instruction in the seventies and early eighties, the years following the introduction of "Modern Math" into the classrooms, teaching themes were: "What does a computer consist of?" - "How is it to be programmed (BASIC or Logo) to solve a problem?", a mainly formal principle. The reversal came by introducing PCs and Macintoshs into the classrooms. By the motto "is anyone here who understands this box?" and "a Macintosh - impossible to open!" and with the improved facilities of readymade programs came the sight of the computer as a mere tool to enhance the mind and concentrate on what to do and how by using it. Until the intention to install it as a preferred teaching and learning aid, supporting or even replacing blackboard, projector, experimental assembly, and 'in the as we hope, not too distant future' as some progressive pedagogues wish, a replacement of school books and notes. Especially the multimedia technique is assumed to bear immense possibilities as well as the use of internet. Commonly quoted: "A today's motorist needs no knowledge of the engine."
