Some general remarks about Web EDEN that are also relevant to JS-EDEN and topical for CONSTRUIT!

The background to notion of construal

Examples of construals

Greedy algorithm (paper + model at WEB-EM-1)
Teaching number bases (paper + model at WEB-EM-1)
Optical Illusions (paper + model at WEB-EM-10)
Modelling the abacus (paper + model at WEB-EM-10)
Problem solving (Sarah Marshall: paper + model at WEB-EM-9)

Adventures in a Lift - supporting material that is complemented by an interactive construal (introduced after the first page of .ppt slides has been presented) that can be used to play-out the unusual lift-use scenario
Digit-cabinet : showing the interactively established nature of the connection between a construal and its referent using very simple definitions of lines and points - together with a simple illustration of how construals can be combined (cf. the JUGS variations poster) and how a construal of a simple scenario (such as opening a filing cabinet drawer) can be corrected / refined
Two versions of the JUGS Model in JS-EDEN one and two in the emile and master versions respectively

Fractional Relationship and Equivalence helper - (Alison Cronick 2003) - I believe this project predates "Visual Fractions" (it may require some updating to work and probably has a style of agency that is more primitive but also more open-ended than the 'program-like' agency in VF)

The above construals are listed because they may be suitable for creating teaching materials. Other construals that are more complex and may be less suitable for teaching purposes include:

  • The Lines model developed for a mathematical research investigation (the core file is essentially a pure script of definitions that uses only very simple operators, but it is not that easy to construct)
  • A piano keyboard construal as developed in conjunction with the agenda set out in EM paper #125 (in a version developed by Elizabeth Hudnott).
  • Hamish Todd's animation of a scientific paper in his WEB-EM-10 submission "Empirical Modelling for understanding cell receptive fields in the visual cortex".
  • The variants of the Dependency Modelling Tool that were developed by Allan Wong (see dmtWong2003) and Richard Myers (see the paper on the DVDMT from WEB-EM-4)
  • Joseph Kizito Bada's HIV/AIDS tree assembling Game which illustrates a generic way to give support to rote-learning of associations and practical techniques for studying learner interactions that are distinctive to EM.


The EM papers mentioned at the outset of C1 were #107 and #096. The first of these discusses some of the illustrative construals mentioned above and there are links to others on the associated webpage. The motivation for making construals, and its relation to programming, are discussed in more detail in EM paper #125 (see the final sections of the paper for instance).
