David Reichard, like S. Raj Chaudhury, a CASTL (Carnegie Academy for the Scholarship of Teaching and Learning) Scholar, has carefully studied the effects of incorporating blogging in his "Free Speech and Responsibility" course. Not only did students blog, but they wrote essays analyzing their own and other students’ blogs: "These essays provided invaluable 'meta' analysis of student learning in the course. Significantly, students described blogs as providing a public record of their own learning, making their process as learners visible to themselves and others."
