The project uses a comparative research design and will generate evidence that is descriptive [case study and observational]. Original data are being collected on educational designers, particularly those developing K-12 science curricula intended for large-scale use, using personal observation and survey research [self-completion questionnaire, structured interviewer-administered questionnaire]. Instruments or measures being used to collect data include interview protocols, survey protocols, and participant observation reflections.
Methods used in this study will include: interviews with designers and document reviews to identify structural project characteristics associated with scaling success; retrospective case studies to identify salient features and lessons learned from more and less successful large-scale design initiatives for science education; and deep dives (involving participant-observation, interviews, focus group discussions, and document analysis) into sustained design practices over an extended period to explore how design teams address key design challenges while developing educational materials for large-scale use.
