In conducting my observational studies of learning I felt that objective observation alone provided insufficient sensory and experiential data to truly understand what was happening in the learning process. For this reason I revised my approach and adopted a duality of perspective. Rather than simply observe students involved in the learning process I subjected myself to the very same process, thereby experiencing a richer influx of data, simultaneously interpreting the events that unfolded before me with the perspectives of both a bystander and a participant.
A conceptual framework of learning on which domain-specific, individualized, theories of learning can be constructed.
