Revision with unchanged content. Dealing with classroom diversity while
trying to engage students in meaningful and rewarding instructional
activities has proven to be a real challenge for both researchers and
practitioners in the field of education. The overall purpose of this
longitudinal study was to investigate the interaction between the
learning, and the Design-Based Research (DBR) processes using a
cognitive flexibility hypertext (CFH) as the object of research. The
first major focus was on the impact of the CFH on students' learning. A
second major focus was the structure of the DBR process, especially the
interplay between research and design when supporting an improved
learning process. While the research and design findings reported for
the two consecutive years represent in and of themselves significant
contributions to the field of DBR, the researcher's reflective analysis
found a theoretical link between the DBR process and the model Expansive
Developmental Research proposed by Activity Theory. The book is
addressed to educational researchers, graduate students, and educational
practitioners interested in successfully implementing innovative
technology-driven designs in complex classroom contexts.
