The project is based on an already tested concept in teacher education, in which student teachers can test and collaboratively reflect on their own teaching at the university in a so-called microteaching setting in a protected space. This is currently still done in face-to-face or hybrid formats, i.e., testing and reflection takes place in the seminar room, although students can be connected via video conferencing system for reflection. In addition, we are currently using the e-portfolio software Mahara in the context of our school internships. The concept for the video e-portfolio is based on the approach of structured online-based feedback on “one’s own” instructional video (e.g. Kleinknecht & Weber, 2020; Weber et al., 2018). We are guided by findings from expertise research that show that factual and conceptual knowledge are not sufficient to act professionally in teaching and counseling situations. In particular, evidence-based action under pressure requires authentic and structured practice (deliberate practice) in addition to the transfer of expertise knowledge. So far, our offerings, for example in the Digital Didactics Workshop of the Future Center for Teacher Education, still focus too little on such collaborative, online- and video-based practice (e.g., distanced reflection is encouraged with “foreign” multi-view videos, but not trying things out and giving feedback). Leuphana could permanently establish such digital testing and reflection spaces as an additional offering – also as part of the Didaktik-workshop.
