Written Argumentation was developed at the Computer Writing and Research Laboratory at the University of Texas. It used Hypercard to create a series of tutorials guiding students through sample texts as a way of introducing them to the Toulmin method of developing arguments. Some highlights:
 |
| The program offered guided heuristics, providing information about Toulmin logic, and then prompting users with questions to test their knowledge. |
 |
| A number of sample arguments were developed. The sample arguments served to illustrate the Toulmin method and provided the bases for the heuristic prompts. |
