Zur Nutzung digitaler Angebote durch Lehrkrafte vor und wahrend der COVID 19-Pandemie zur eigenen Fort- und WeiterbildungOn the use of digital offers by teachers before and during the COVID-19 pandemic for continuous professional development

Further professional development significantly contributes to the quality of teaching and is usually mandatory for teachers. In order to make further professional development attractive and to adapt the organization and offer to the needs of teachers, regular analyzes of further professional development behavior and wishes are required. Digital alternatives can complement face-to-face professional development. During the COVID 19 pandemic, there has been a lot of development in the field of digital media in schools. In this article, we examine how teachers use digital media for their own further education and training and whether usage behavior has changed since the beginning of the COVID 19 pandemic.

Students' Perception of an Individualized Open Lab Learning Experience during the COVID-19 Pandemic in German Chemistry Teacher Education

Teacher education needs to combine training in content knowledge, pedagogical knowledge, and pedagogical content knowledge (PCK). One important part of PCK in science education is knowledge about school science practical work to promote learning by scientific inquiry and about the nature of science. In Germany, practical seminars and lab sessions dealing with "school-type"practical work are mandatory for any preservice chemistry teacher education program. Since practice in handling school-type lab equipment is considered important, courses regularly require attendance in practical sessions. These practical experiences are seen as irreplaceable by digital and video materials when it comes to the development of practical and manual skills. This paper reports on the replacement of a traditional course based in a face-to-face seminar combined with half-day lab sessions for a whole cohort of students. This course was replaced by an individualized, digitally supported, open lab learning experience for prospective secondary school chemistry teachers. The change was implemented due to social distancing rules caused by the COVID-19 pandemic. Elements of the course structure are discussed and related to how students experienced the course. © 2022 The Authors. Published by American Chemical Society and Division of Chemical Education, Inc.
