In 2011, The California Science Center (CSC) contracted ETI to conduct a two-year summative evaluation of the Alexander Science Center School (ASC School), a neighborhood, affiliated charter school in LAUSD for K-5th grade students. The purpose of the evaluation is to determine the impact the ASC School has on its students compared to students in traditional LAUSD schools, as well as lay the groundwork for future evaluations. ETI developed a Quasi-experimental research design used to understand the school’s impact on students’ critical thinking, problem-solving skills, attitudes about learning and academic achievement. An attitude survey about students’ curiosity, sense of discovery, and attitudes toward science learning were developed in conjunction with CSC staff and relevant stakeholders. ETI also examined parental involvement and their ability to support their children’s learning environment.
