To revitalize humanities courses and to improve student thinking, a workshop for faculty members of the University of the Sacred Heart (Puerto Rico) will cover two models of collaborative learning, collaborative group work and peer criticism. In collaborative group work, students should be able to learn how to reach a consensus about a specific task, to generate ideas, and to share those ideas with other members of the group without the direct intervention of the teacher. In peer criticism, students will learn how to evaluate others' work, make judgments based on facts, and to express their opinions in coherent and persuasive ways. Exercises on finding the organizing principle of a reading assignment will improve students' reading ability. The last part of the workshop will focus on developing teachers' attitudes toward students' work that will encourage, not discourage, improved student writing. Faculty members will be surveyed both immediately after the workshop and at the end of the following semester to see how many of these methods they actually use and what suggestions they have formulated based upon their experiences.
