It may be that like biology there is simply not enough class time available to teach it. But whatever the case we need to have gone through the issues of having thought about it and being able to articulate why informatics cannot be taught, if in fact it cannot be. Acknowledgement I wish to acknowledge the advice of my colleague Academician Petar Kenderov of the Bulgarian Academy of Sciences' Institute of Mathematics and Informatics for certain advice which I found useful in writing this paper. I did note above that the Bulgarians can be regarded as the founders of the IOI, having hosted the first IOI in 1989 at Pravets. The following are two contemporary American publications on the teaching of algorithms in schools.
More references obviously exist on specific syllabus issues.
