These appendices accompany the report "Final Report of the i3 Impact Study of Making Sense of SCIENCE, 2016-17 through 2017-18." Science education has experienced a significant transition over the last decade, catalyzed by a re-envisioning of what students should know and be able to do in science. That re-envisioning culminated in the…

This paper reports results from a study investigating the efficacy of a proportional problem-solving intervention, schema-based instruction (SBI), in seventh grade. Participants included 806 students with mathematical difficulties in problem solving (MD-PS) from an initial pool of 1,999 seventh grade students in a larger study. Teachers and their…

The purpose of this study was to document the design, classroom implementation, and effectiveness of interactive online units to enhance science learning over 3 years among students with learning disabilities, English learners, and general education students. Results of a randomised controlled trial with 2,303 middle school students and 71…

Interest has been growing in the role of students' attitudes, beliefs, and dispositions as key factors that can support or inhibit student success. A large body of emerging evidence, including multiple randomized controlled trials, shows that interventions that target academic mindsets, attitudes, and beliefs about the nature of ability and the…

In the United States today, more jobs than ever before require at least some postsecondary education. Yet too many young adults are either not enrolling or not succeeding in college. This scenario exists across many different types of communities, but schools in rural areas, particularly those with large populations of low-income students, face…

In August 2010, the Smithsonian Science Education Center (SSEC) received a grant of more than $25 million from the U.S. Department of Education's Investing in Innovation (i3) program for a five-year study to validate its Leadership Assistance for Science Education Reform (LASER) model in three very diverse regions of the United States: rural North…

College and career aspirations are important to the development of students' short and long term educational and personal goals. Although students rely on information they receive and are influenced by experiences in which they engage in a variety of settings, for many, school is an important source of college and career information. How students…

The Bill and Melinda Gates Foundation invested in the Literacy Design Collaborative (LDC) as one strategy to support teachers' and students' transition to the Common Core State Standards (CCSS) in English language arts. This report provides an early look at the implementation of LDC in sixth-grade Advanced Reading classes in a large Florida…

Sixth graders participating in the "Too Good for Drugs" (TGFD) prevention program in comparison to 6th graders not participating show different results by student risk level. Sixth graders from 20 middle schools were randomly assigned to receive the intervention and those from 20 paired middle schools assigned to serve as controls (N =…

The purpose of this study was to: examine differences in students' perceptions of their noncognitive skills and school environments by race/ethnicity, and explore whether students' perceptions of their noncognitive skills and school environments were related to three outcomes that have been identified in the research as mattering most for a…

This study examines the effects of Connected Mathematics Project 2 (CMP2) on grade 6 student mathematics achievement and engagement using a cluster randomized controlled trial (RCT) design. It responds to a need to improve mathematics learning in the Mid-Atlantic Region (Delaware, Maryland, New Jersey, Pennsylvania, and Washington, DC). Findings…

The study reported in this volume adds to the growing body of evaluation studies that focus on the use of NSF-funded Standards-based high school mathematics curricula. Most previous evaluations have studied the impact of field-test versions of a curriculum. Since these innovative curricula were so new at the time of many of these studies, students…

Successful change in schools is planned, expected and managed with the objective focused on benefiting the students, not just converting the staff. This investigation is a case study of a public school district that opted to implement curricular change following an examination of the district's performance toward adequate yearly progress. This…

This study explored the long-term benefits of the Reading Recovery ® program for economically disadvantaged students who were successfully discontinued after the first grade. The hypothesis was tested that students exiting first grade with grade-level reading abilities and with similar low socio-economic status (economically disadvantaged), who…
