Ursula Rutherford is developing evaluation instruments to assess student learning in an evolving undergraduate engineering curriculum at Coventry University that is increasingly adopting activity-led learning (ALL). The research has three interconnected strands to identify teaching quality indicators, investigate how they can be recognized, and evaluate their effectiveness. However, the rapid changes in modules and student cohorts pose a challenge for validating new instruments. Rutherford is seeking ideas from others on how to demonstrate rigor in the research and reliability of instruments developed in this environment of constant change and shorter feedback cycles.
