In two-stage exams, students produce some academic work individually then do the same work again in small groups. Both works contribute to the individual grade. Prior research shows that students perceive that the feedback dialogue they engage in, during two-stage exams, aids their learning. Also, outcome studies show that this method benefits individual student learning. However, there is no research on the internal feedback students generate during two-stage exams, when they compare their own individual performance against the group discussion and the developing group output. To investigate this, internal feedback was made explicit, in a two-stage exam, by having students write a feedback commentary on their own learning at both the individual and group stages. Analysis showed that students not only generated content and process feedback but also self-regulatory feedback, and that this feedback was of a higher quality than and went beyond that which the teacher provided. The implications for future implementations of two stage exams are considered as well as how this research adds to the literature on internal feedback.

We are studying the crystallization and annealing behavior of high performance polymers, like poly(p-pheny1ene sulfide) PPS, and poly-(etheretherketone), PEEK. Our purpose is to determine whether PPS, which is similar in many ways to PEEK, undergoes reorganization during annealing. In an effort to address the issue of reorganization, we are studying solution grown single crystals of PPS as model materials.Observation of solution grown PPS crystals has been reported. Even from dilute solution, embrionic spherulites and aggregates were formed. We observe that these morphologies result when solutions containing uncrystallized polymer are cooled. To obtain samples of uniform single crystals, we have used two-stage self seeding and solution replacement techniques.
