Bernd Sahre:

Effect of general and specific reflection prompts.

Reflection can be defined as ”mechanism to learn through experience“ [1]. Wolfbauer et al. have shown in [2] that reflection is possible in trainees with the help of a chatbot and a reflection script. This master thesis deals with the question whether a successful application of the reflection script with a chatbot is transferable to other domains. This is tested in a use case in a medical context with residents of the CharitÅLe Berlin, where the reflection script from [2] is additionally contrasted with a control group with a general reflection prompt [3][4] and the number of reflective utterances is compared. In addition, a second use case tests the extent to which reflection is possible independent of domain knowledge. Here, the control group also receives a general reflection prompt.

The result of the two studies is that a group that reflects using the reflection script fromWolfbauer [2] makes an average of 4.27 reflective utterances – coded using reflection codes according to [5] – makes, while a comparison group with a general reflection prompt achieves 2.84 reflective utterances. No correlation with the number of reflective utterances was found with prior knowledge of the object of reflection – as measured by the Security Behavior Intention Scale [6] – nor with educational attainment. Interaction with the chatbot was perceived as positive. Further development of the reflection script with the support of a chatbot, for example adaptively according to the user’s needs and expressions, may therefore be promising.
