This award creates a new Research Experiences for Teachers (RET) Site focused on Big Data and data science at the University of Louisville. Each summer, ten high school Science/Technology/Engineering/Mathematics (STEM) teachers will participate in research activities with faculty in labs at the University of Louisville. The teachers will be recruited from Jefferson County Public Schools and the Ohio Valley Education Consortium. Teachers in this site will apply fundamental data science techniques and learn Big Data principles while investigating real world problems with social relevance. The fast pace of low-cost technological innovation and data-centered operations have led to an explosion of data that can be used to solve problems and provide new insights for the future. This includes projects involving areas such as human welfare, healthcare, smart cities, and robotics. The participating teachers will translate their research experiences and knowledge into classroom practice by developing instructional modules and course materials that they will introduce in their classrooms and share with other teachers in their school districts. These activities all contribute to the formation of a community of practice in partnership with the University of Louisville faculty mentors that has the potential to significantly enhance STEM education in the participating school districts.
