The document summarizes a case study that used the Herrmann Brain Dominance Instrument (HBDI) assessment to improve learning at Yale College in Wales. It discusses how the HBDI was used to identify students' high and low thinking preferences, and teachers then selected teaching strategies targeted to students' preferences. Assessments before and after the targeted teaching interventions showed improved scores across various subjects. Interviews found students were more motivated and confident in their learning, while teachers felt it created better focus on learning. The results suggest that using cognitive profiling to differentiate instruction can positively impact educational outcomes.
