This module adopts and adapts an exercise found at the Southern Illinois University at Edwardsville website on assessment: www.siue.edu/ deder/assess/cats/muddy3.html. Developed first by Harvard Professor Mosteller, it has been modified from the Edwardsville version by having students identify both a difficult (i.e., muddy) and a clear point to balance negative and positive feedback. Students work through an engineering or computer ethics module. (These can also be found at Connexions published under this author’s name.) After completing the module they are asked to fill in the form attached to this module. Results of this feedback are shared with the students and used to help develop derived copies of the modules. This module is being developed as a part of an NSF-funded project, "Collaborative Development of Ethics Across the Curriculum Resources and Sharing of Best Practices," NSF SES 0551779.
