Before you start throwing yourself in the mountains of potential studies you can learn about in IB Psychology, it’s important to remember that studies are only as helpful as the concepts they demonstrate.
It’s not about how much you can remember of the study: it’s about how well you can use the study to demonstrate a concept. And by concept, I mean relationship. Understanding psychology is all about understanding relationships. So don’t just blindly read through studies and try to memorise details: try to analyse the studies in order to understand the significant relationships between variables and behaviour that they are demonstrating.
It’s important that students can think critically about research. Many teachers spend time on the concept of internal validity, but you may be interested to read my rationale for not teaching students how to evaluate existing research based on internal validity.
