Design-based Research (設計本位研究法，BICD7010) is a methodological course for doctoral students to discuss the emerging research method in educational technology studies. This course will be co-taught by Prof. Hsiu-Ping Yueh (Dept. of BICD; Dept. of Psychology) and Prof. Weijane Lin (Dept. of Library and Information Science).  Introduction to DBR will be firstly given as a systematic but flexible methodology aimed to improve educational practices through iterative analysis, design, development and implementation.  Related studies using DBR will be reviewed, and finally a term project to conduct a DBR study will be assigned to develop students’ comprehensive understanding of the research method.
