When the editors of this book asked us to write a chapter that reflects our work and thoughts about issues that relate to change and improvement of institutions, environments, and people, we immediately decided to focus on the college classroom and how college teachers and students adapt to new forms of instruction. In our own research we examined the adaptations that college teachers make to existing teaching methods in order to take into account the way students learn and we also analyzed the students' response to these innovations. More specifically, we studied students' developing interest in a course as a function of their changing appraisal of affordances and constraints in the learning context. We also examined the emotions that were triggered in the college classroom and how these emotions influenced the students' self-assessment of their self-regulation strategies. In this chapter we wil! focus mainly on our studies that focused on the students' expertise development in relation to an important academie skill, namely scientific writing. We wil! examine how self-regulation of scientific writing develops and how it is affected by students' beliefs about the quality of the learning environment and the positive and negative emotions they experience while engaged in the course.
