We published our first set of Connections Academy efficacy reports containing independently assured efficacy statements in 2018. We went on to build on that body of research, and updated our reporting with new findings in 2021. Our latest study compared Connections Academy students' state test scores in reading and math with students in…

Our study used a case-control matching design to assess the influence of a voluntary tutoring program in improving first-year students' Grade Point Averages (GPA). To evaluate program effectiveness, we applied case-control matching to obtain 215 pairs of students with or without participation in tutoring, but matched on high school GPA and…

There has been a national call to transition away from the traditional, passive, lecture-based model of STEM education towards one that facilitates learning through active engagement and problem solving. This mixed-methods research study examines the impact of a supplemental Peer-Led Team Learning (PLTL) program on knowledge and skill acquisition…

Background/Context: Student utilization of complex enrollment patterns has been identified as a significant recent development in higher education. Nearly a dozen different multi-institutional attendance patterns have been identified, including co-enrollment. Co-enrollment is simultaneous enrollment at two or more colleges or universities during…

The 6-yr degree-completion rate of undergraduate science, technology, engineering, and mathematics (STEM) majors at U.S. colleges and universities is less than 40%. Persistence among women and underrepresented minorities (URMs), including African-American, Latino/a, Native American, and Pacific Islander students, is even more troubling, as these…

This is the fourth-year report in a five-year evaluation of the Milwaukee Parental Choice Program (MPCP). This report features analyses of student achievement growth three years after the authors carefully assembled longitudinal study panels of MPCP and Milwaukee Public Schools (MPS) students in 2006-07. The general purposes of the evaluation are…

This study explores the effects of a Two-Way Bilingual Immersion (TWBI) program on language majority and minority students. The fundamental hypothesis was that the process of receiving instruction in two languages (English and Spanish) throughout elementary school (i.e., attendance at a TWBI school) would help the native Spanish-speaking students…

In this set of four supplemental tables, the authors compare the baseline test scores of the treatment and matched control group samples observed in each year after KIPP entry (outcome years 1 to 4). As discussed in Chapter III, the authors used an iterative propensity score estimation procedure to calculate each student's probability of entering…

The Knowledge Is Power Program (KIPP) is a bold effort to create a network of charter schools designed to transform and improve the educational opportunities available to low/income families. KIPP schools seek to actively engage students and parents in the educational process, expand the time and effort students devote to their studies, reinforce…

In the present study, 49 fifth-graders enrolled the KIPP D.I.A.M.O.N.D. Academy in the 2002-03 school year were individually matched to control student from five feeder schools on the basis of ethnicity, free-reduced lunch status, and fourth-grade achievement on the Reading and Mathematics subtests of the Tennessee Comprehensive Assessment…
