Gary Comstock (professor of philosophy at Norh Carolina State University):

 " Before Rationale, I was only able to lecture at my students about the skill of evaluating arguments. 

After Rationale, I have the technology I need to help them actually acquire the skill." 


Kees van EE, Stafbureau O&O, Hanzehogeschool:

' Finally: a method that provides lecturers with real tools to help students getting their thinking and writing to a higher level.

And even more: the excellent Rationale program helps you making a good structure for your reasoning, arguments, analyses and evaluation.'

From the Abstract:

'This paper reports on a case study in which the use of the Rationale software was investigated to analyse the argumentation structure of a Dutch expert witness report in a criminal case. The underlying motivation of the case study was to explore the usefulness of argumentation visualisation software for increasing a judge's understanding of expert reports and for assisting him or her in asking the proper critical questions to the expert. By way of an initial exploration of this usefulness, an expert report was analysed with the Rationale software. The visualisation was informally discussed with a legal expert, who was generally positive but also expressed some concerns and expected that the main usefulness of the tool is in training and education of judges.'

- Argument Mapping in Your Subject:

'This website provides resources intended to support university-level educators incorporate argument mapping into their teaching, with a particular focus on how argument mapping can be incorporated into a standard one-semester subject in almost any discipline.'

- The Wiki site of Rationale (mirrorsite). On this site you can find many argument maps (made in Rationale ) on different subjects. Especially noteworthy are the sections on patterns of argument and the section on argumentation schemes and their related critical questions (cf. the work of Walton, Pollock and Katzay & Reed).

- An example of an argument map made a s the first step in writing an essay or paper. Note the ease and precision with wich a teacher can provide the student with feedback before he starts with time consuming wrestling with often badly structured text.

- Examples of the use of argument maps in secondary and tertiairy education and a general Teachers Guide.
