Resumen
Writing a historical paper about something you yourself are heavily involved in is clearly difficult; the result is bound to be personal and idiosyncratic and might well sound presumptuous. The author thus viewed an invitation to write about statecharts for the third History of Programming Languages conference in 2007 as an opportunity to put the language in a broader perspective. This article is a greatly abridged version of the resulting conference paper. The implicit claim is that the emergence of the language brought to the forefront a number of ideas that today are central to software and systems engineering, including the general notions of visual formalisms, reactive systems, model-based development, model executability, and full code generation.

Resumen
This article focuses on computer science educators and explores the various options available to improve the quality of education imparted by them. According to the authors, beyond the mastery of core material, computer science educators should also be familiar with a significant body of material that will expand their perspectives on the field and consequently, enhance the quality of their teaching. Computer science educators should have the additional ability to convey this knowledge to others correctly and reliably, to teach the skills, to provide perspective and to infuse the students with interest, curiosity and enthusiasm. All this requires the educator to be more of a scientific intellectual, at least as far as the field in question is concerned. While some of this is a matter of personality and natural aptitude, some can be acquired by being exposed to material that goes beyond the technical core parts of the field. In addition to being just knowledgeable, a compute science educator should also try to keep up to date with relevant developments in the field of computer science education.
