The purpose of the study is to compare the outcomes of reflecting on difficult problematic experiences with those of reflecting on positive experiences. The authors focused on three outcome areas: the content of teachers' resolutions after reflecting because decisions need to be productive, their motivation to act on their decision because teachers need to implement their decision because teachers need to implement their resolutions, and the emotions they have during the process of reflection because emotions are very influential to thinking and learning. In an exploratory study, 16 student biology teachers were asked to reflect on two problematic and two positive teaching experiences and to take notes during the reflection process.
