Math in Focus Paper Published in JREE
Chief Scientist Andrew Jaciw’s paper entitled Assessing Impacts of Math in Focus, a “Singapore Math” Program was accepted by the Journal of Research on Educational Effectiveness. The paper reports the results of an RCT conducted in Clark County (Las Vegas, NV) by a team that included Whitney Hegseth, Li Lin, Megan Toby, Denis Newman, Boya Ma, and Jenna Zacamy. From the abstract (available online here):
Twenty-two grade-level teams across twelve schools were randomized to the program or business as usual. Measures included indicators of fidelity to treatment, and student mathematics learning. Impacts on mathematics achievement ranged between .11 and .15 standard deviation units, with no differential impact based on level of pretest [or] minority status.
