Evaluation
Related to students' uneasiness about evaluation is the focus on student development, observation, process, and thought. For a change, students are evaluated on what they learn, in the sense that students are evaluated on the demonstration of their learning. Although this is why teachers give tests and quizzes and assign papers (to see what students know/have learned), students (more than likely) have never consciously thought of their learning in terms of demonstration. Therefore, they are immediately uncomfortable. In addition, students are uncomfortable because they must demonstrate their learning in ways that are new to them.
If teachers remind students that they are mostly writing about the one subject they know the best — themselves — and that the evaluation of their work (and their final course grade) is still partly based on the quality and quantity of their work.
NOTE: Students that enter the class as strong writers are particularly nervous about the development/improvement aspect of the LRO, since they worry they will not be able to demonstrate any development (since they feel they have no room to improve).
I tell such students that there is always something (even if it seems relatively minor) that they can work on or learn more about and that the quality of writing is still very important.
