Definition:  The Scientific Research Basis of FOSS

The Full Option Science System (FOSS) is research based.  Educational research, which conforms to the standards of scientific research, provides the theoretical basis for the FOSS program design.  The accumulated results from decades of educational research on teaching and learning guided the development of the FOSS instructional methodologies.  Educational research is rigorous, objective, and scientific in design.

The FOSS program, however, was created using more than a scientific research model.  FOSS was created using a research and development model.  Not only was the program based on academic educational research, it also involved a systematic approach to product development, testing, revision, and retesting that required more than two years of intense work to complete each module.  The FOSS program development was a kind of educational research itself.  The fact that the project staff set out to uncover new knowledge—to understand how to better teach science to elementary students—thrusts the FOSS curriculum development process into the research environment.  All 26 K–6 modules and middle school courses (content-specific curriculum units) were developed using the 2-year-plus development process. 

The implicit question that underscored the FOSS research and development process for the K–6 program was, “what is the most efficient, effective way to teach science content, scientific principles, and scientific habits of mind to elementary-school students?”  The answer to that question has been the consuming occupation of the FOSS development staff for more than 15 years, and will continue to dominate the work of the staff into the foreseeable future.  The reason the job is not “done” is because knowledge in the field of science education is continually evolving.  The advances in understanding and improvements in practice and products are incremental.  These two fields of research inform, guide, and give coherence to the FOSS program development process.
