The broad purpose of the research interest group (RIG) is to advance the mission of NARST by maintaining the rigor of science education studies and the validity of their findings; in turn, keeping our work relevant to improving science teaching and learning. More specifically, our goal is to facilitate learning of and discussion about philosophical (i.e., ontological, epistemological) issues related to research methodology, as well as about recent developments and best methodological practices for science education research. The RIG will focus on methods and their applications in both the qualitative and quantitative traditions.
