Ejs packages a model's narrative description together with the computer simulation in a single jar file in order to provide a more complete modeling cycle.

Di Sessa defines computer-literacy as the ability to be able not only to read from a computer, i.e. use Web browsers, spreadsheets, and/or text processors, but also the ability to write to a computer, i.e., to program it. He claims that every person with higher education, particularly in science, should learn to program (although this may have different interpretations) a computer.
