Today we're chatting on a topic that's crucial for anyone in the field of education research or anyone curious about quality survey construction and robust survey scale validation. We're talking about Rasch model analysis with Associate Professor Michael Carey. He uses a cake baking metaphor to explain how the Rasch model technique is applied to survey design and validation in plain English. He also refers to some recently published STEM research as examples of how a large 77-item preservice teacher TPACK self-audit instrument was developed and validated:

The development and validation of a self-audit survey instrument that evaluates preservice teachers’ confidence to use technologies to support student learning. Michael D. Carey, David A. Martin, and Natalie McMaster. 2024. International Journal of Research & Method in Education. https://doi.org/10.1080/1743727X.2024.2341714

Dr Geoffrey Chapman is a lecturer at CQU in Sydney and passionate about gamification. He has introduced his love for escape rooms into his tertiary classroom. During Covid, he translated them into the online learning space and is now using them in his postgraduate teaching. They are great for team building, clear objectives and a bit of time pressure. His students love them. Get in touch with Geoff if you would like to learn more. g.chapman@cqu.edu.au
