Cathy Lachapelle leads the EiE team responsible for assessment and evaluation of our curricula. This includes the design and field-testing of assessment instruments and research on how children use EiE materials. Cathy is particularly interested in how collaborative interaction and scaffolded experiences with disciplinary practices help children learn science, math, and engineering. Her work on other STEM education research projects includes the national Women's Experiences in College Engineering (WECE) study. Cathy received her S.B. in cognitive science from the Massachusetts Institute of Technology and her Ph.D. in educational psychology from Stanford University.

Dr. Christine Cunningham is an educational researcher who works to make engineering and science more relevant, accessible, and understandable, especially for underserved and underrepresented populations. A vice president at the Museum of Science, Boston since 2003, she founded and directs Engineering is Elementary™, a groundbreaking project that integrates engineering concepts into elementary curriculum and teacher professional development. As of September 2014, EiE has served 6.2 million children nationwide and 71,000 educators. Cunningham has previously served as director of engineering education research at the Tufts University Center for Engineering Educational Outreach, where her work focused on integrating engineering with science, technology, and math in professional development for K-12 teachers. She also directed the Women’s Experiences in College Engineering (WECE) project, the first national, longitudinal, large-scale study of the factors that support young women pursuing engineering degrees. Cunningham is a Fellow of the American Society for Engineering Education and was awarded the 2014 International Society for Design and Development in Education Prize. She holds B.A. and M.A. degrees in biology from Yale and a Ph.D. in Science Education from Cornell University.

Abstract

HLM modeling of pre/post-assessment results from a large-scale efficacy study of elementaryengineering (Curriculum Evaluation)As engineering enters K-12 classrooms, it is important that curricula and activities engage students andfoster student learning of engineering concepts. This paper reports on an efficacy study that isexamining the effects of a set of critical curriculum design components on student learning ofengineering and science concepts at the elementary level. Critical components include that: (a)engineering content is introduced in a context, (b) students learn about and use the engineering designprocess, (c) engineering challenges specify a challenge and constraints and permit many possiblesolutions, (d) children use math and science to design solutions, (e) children use failure constructivelyand design iteratively, and (e) students work collaboratively. These components are present in thetreatment curriculum. The comparison curriculum has the same learning objectives but does notembody these principles.Our large-scale research study involves ~250 teachers from 150 schools in 3 regions (Massachusetts,Maryland, and North Carolina). Teachers were randomly assigned (at the school level) to treatment andcomparison conditions. After engaging in a curriculum-specific summer professional developmentworkshop, teachers implemented a curriculum unit which was approximately two weeks in length withtheir students, who were in grades 3-5. A large number of assessments, surveys, observations, and videodata were collected; those that will inform this paper include: • Student demographic data • Student pre-/post-assessments that probe their knowledge of engineering concepts and science concepts • Teacher instruction logs that report the content of lessonsWe are using an ANCOVA model implemented using Hierarchical Linear Modeling (HLM, Bryk &Raudenbush, 1992) to measure effect sizes of the treatment and moderating variables on student post-assessment scores. At Level 1, we model student data; at Level 2, we model classroom variables; and atLevel 3, we model the school-level variables.In this paper, we will present the models we have developed using HLM, including the range ofmoderators included in the model, and why we have included them. We will explain the advantages ofusing HLM to examine data from a large number of students, and we will interpret HLM output.Mostimportantly, we will describe the results of our statistical model. A preliminary round of analysis foundthat the treatment curriculum, student socio-economic status (SES), and student prior knowledge affectstudent outcomes. Therefore we expect the analysis we are currently undertaking to indicate that: • use of the treatment curriculum, as compared to the control curriculum, improves student understanding of science and engineering, • student SES negatively affects student outcomes, and • student prior knowledge as assessed by the pre-assessment predicts student outcomes.Finally, we expect to report that school factors such as the percent of low-income students in the schoolare important moderators of student outcomes.Our study is one of the first large-scale efficacy study of an engineering curriculum. The role that thecritical components play in student learning is important and should guide the work of other curriculumdesigners.Bryk, A. S., & Raudenbush, S. W. (1992).
