Learning to reason in an informal math after-school program

Abstract: This research was conducted during an after-school partnership between a University and school district in an economically depressed, urban area. The school population consists of 99% African American and Latino students. During an the informal after-school math program, a group of 24 6th-grade students from a low socioeconomic community worked collaboratively on open-ended problems involving fractions. The students, in their problem solving discussions, coconstructed arguments and provided justifications for … Show more

“…These features have been documented by Henningsen and Stein (1997) to include opportunities for multiple representations, multiple solutions, and mathematical discussion. According to Mueller and Maher (2008), open-ended challenging tasks that allow for exploration, multiple representations and multiple strategies contribute to the co-construction of ideas and thus to the development of multiple forms of reasoning. The tasks should be presented to students as strands of related problems that can be revisited over time and in different contexts, thus enhancing students' opportunities to overcome obstacles in problem solving.…”

“…When given the opportunity to reason about mathematical knowledge in a supportive environment, students as young as elementary school can create conjectures, reflect upon and evaluate them, and try to convince others to accept these justifications (Maher & Davis, 1995;Yackel & Hanna, 2003). Given contexts that allow students to share their ideas with others, and participate in mathematical discussions, debates, and reasoning about mathematics, students are able to offer convincing arguments that indicate various forms of reasoning in the development of solutions to problems (Maher, 2005;Maher & Davis, 1995;Maher & Martino, 2000;Martino & Maher, 1999;Mueller & Maher, 2008).…”

“…Research on student thinking shows that learners are capable of making reasoned and insightful conjectures (for examples, see Balacheff, 1988;Boero et al, 1999;Ellis, 2007a;2007b;Herbst, 2006;Lee and Sriraman, 2011;Mariotti, 2006;Martin and Pirie, 2003;Mueller and Maher, 2009;Yerushalmy, 1987Yerushalmy, , 1993. This body of research provides a template for the types of conjecturing activities that students could engage in during instruction.…”

“…Tekst zadatka opisuje realnu situaciju koja treba da se reši primenom matematičkog postupka koji obuhvata definisanje poznatih, odnosno nepoznatih vrednosti. Matematički zadaci predstavljeni u numeričkom formatu su jednostavniji s obzirom na to da podrazumevaju samo izračunavanje vrednosti postavljenog izraza i stoga ih učenici bolje savladavaju u odnosu na tekstualno predstavljene zadatke (Carpenter, Cobitt, Kepner, Linquist & Reys, 1980;Mueller & Maher, 2009). …”
