The study is part of a group of studies on Project LEAP, for Learning Early Algebra Progression, a program developed at the University of Wisconsin-Madison, TERC, the University of Texas at Austin, City College of New York, and Merrimack College.
鈥淲e鈥檙e not talking about taking a traditional [algebra] curriculum and pushing it earlier in the sequence,鈥� said Rena Stroud, a senior researcher for the project at Merrimack College. 鈥淲e鈥檙e talking about what algebraic thinking looks like in early grades.鈥�
The three-year curriculum includes 18 weekly hourlong lessons, in each of grades 3-5. In the lessons, teachers introduce students to generalizing, representing, justifying, and reasoning about numbers and correct misconceptions that often trip up older students. Researchers randomly assigned 440 3rd graders in nine high-poverty schools to get either the algebraic lessons or standard grade-level arithmetic. By the end of 5th grade, Project LEAP students performed 13 percentage points higher in math than those in the control group.
