I am developing a research project and I am working on this theme. I wonder if there are scientific papers on this subject, to help me complete the literature review.
A place to look might be in Scott Thomas' book understanding comics. http://scottmccloud.com/2-print/1-uc/ I do not have my copy with me right now but seem to recall that he did cite some relevant studies and had some references within the book.
You could also look at - A Story-based Simulation for Teaching Sampling
Distributions by Stephen Turner and Alan R. Dabney. The paper is a report on a simulation using aliens to teach the basic concepts of Statistics. It is quite interesting.
Sorry, I may have misunderstood your use of "comic". I had in mind a humorous person, but it seems like you are interested in comic as a graphic presentation that does not have to be humorous. :-)
It's all right. I mentioned the use of comics as a methodological resource in adult education, as appropriation of writing instrument, for example, regardless if they are in humor or not. I wonder if there are other scholarly articles about comics in adult education, which could contribute to my research project. Anyway, thank you for the suggestion.
I suggest for you to start exploring the effectiveness of project based learning with comics involving adult learners. It's an emerging practice in adult education.
