My advisor suggested me use learning by design as my theory framework of my research on e-p.

Meanwhile, we will have the class of Design based research.

I know they are different things because design based research is more like a research methodology when learning by design is a learning theory.

But today maybe we can combine both . Because my intentional research participants, the doctoral student in instructional technology program, are people who are doing or will doing research by themselves.

When I apply blog into e-p of the first year review, it will be a strategy of learning by design for the first year doctoral students.  Meanwhile, that will be a design based research because this e-portoflios research is based on design an innovation on the current e-portfolio base.

I am still not sure whether my though is correct. I need read more.
