A system, named Reflex, for handling reflection documents is presented. Writing a reflection document is a mandatory last step when carrying out Master’s or Bachelor’s theses within all education programs at the Faculty of Science and Engineering at Linköping University. In the reflection document the students are expected to reflect on both the thesis work and the outcome of the entire education program. The reflection is structured according to the four sections of the CDIO Syllabus plus additional aspects around the process of the thesis work and the program as a whole. Reflection documents have been used for more than ten years, but via the introduction of Reflex in 2023 the process is entirely electronic and all texts from the reflections are stored in a searchable database. This enables efficient and systematic analyses of the texts, which can be used for evaluations of entire programs as well as selected aspects. Two examples of such analyses are presented in the paper. In addition, the thesis work process is presented, together with a description of how the system Reflex works.
