With the advent of web-based programs that automate the scoring of exercises, materials are now being developed from the outset with the capabilities of the web in mind. Materials developed without consideration of the web's capabilities, on the other hand, must be retrofitted. Texts that are retrofitted to the web have the advantage of being pedagogically, not technologically, driven. With adequate attention paid to the pedagogy of adapting such texts to the web, these texts can compete on their own merits with products that are designed from the outset for use on the web. This paper discusses some of the complications of working with retrofitted materials and presents some solutions to common problems. (Contains 4 figures and 1 table.)
