Since its introduction four years ago, iLrn has quickly gained popularity.
Use of iLrn and the other electronic products Lunar Logic developed for Thomson has doubled each year since 2002, said Blake Hutchins, senior vice president of operations.
I have used iLrn's online textbooks for eight semesters with more than 700 students.
The site provides an instructor with a personal site, My Workplace, from which one can customize titles by reordering chapters, adding and/or deleting portions, inserting new content from other iLrn titles, or creating a new chapter from scratch.
None of the other traditional, static textbooks or online content providers that I have investigated have been able to provide the same level of depth of scholarship and the ability to engage the student as effectively as the iLrn's robust and innovative presentation of Western Civilization.
