The importance of active-learning, student support, and peer teaching networks: A case study from the world’s longest COVID-19 lockdown in Melbourne, Australia
In the Australian state of Victoria, the city of Melbourne endured the world’s longest number of lockdown days, with severe government health orders and travel restrictions in place for extended periods of 2020 and 2021. In common with others, we found the provision of field teaching in introductory geology, structural geology, and volcanology, and the online replacement of practical instruction in petrology and petrography to be the greatest pedagogical challenges. We developed and used a range of different virtual field excursions that, given time and travel constraints imposed on us, were necessarily “low-tech” and non-immersive. Despite this, our students largely engaged enthusiastically with the virtual excursions, met many preexisting learning goals, and gained additional skills, particularly in regional-scale geological synthesis. In teaching petrology and petrography online, curated resources improved student understanding of some fundamental concepts, and it was advantageous that students were all assessed using identical imagery, rather than one sample from a non-identical class-set. On the other hand, we found we were less able to train students in the advanced skills of thin section interpretation. Assessment changes associated with online teaching have resulted in a permanent shift from low-level recall-style assessments to instead emphasizing higher-level synthesis and “geological thinking” skills. Our efforts throughout the pandemic demonstrated the value of instructor-student engagement and yielded teaching resources that have subsequently enhanced our face-to-face teaching and increased flexibility for students. Moreover, the COVID-19 pandemic has highlighted the importance of collaborative teaching practice and we have increasingly seen the benefits of local and national-scale teaching networks for peer support and for resource sharing
