(1999). Rewards can also have undesirable side effects if they are tied to competitions that create winners and losers. Because it has also been a target of concern and criticism, we devote specific attention to it and to the warrants for and conditions of its use. He is careful to connect what are often two disjointed fragments: a rule for adding zeros when multiplying by powers of 10 greater than one and a different rule for moving the decimal point when multiplying by powers of 10 less than one. It is to generate and uncover different solution strategies, including modeling situations and using representations, to explore and justify those strategies, and then to find similarities and differences between different solutions. He does not tell them what to do; instead, he uses the task as the medium for the lesson development. Fuson, K.C. 155–180). The research indicates that these cooperative group methods are likely to have positive effects on achievement and on other social and psychological characteristics.44 The effects on achievement appear to be related to the use. Review the slide set titled NRC Math Proficiency Standards located on the summer work page of the course website as well as the background information above. “Oh, I see!” exclaims Michelle excitedly, doing some calculations off to the side of the transparency. She asks the children to compare solutions: “How is Mina’s solution like the one Brian showed? (1987). The QUASAR Project: The “revolution of the possible” in mathematics instructional reform in urban middle schools. What did we decide happens to the product when we multiply a decimal by 10, 100, or 1,000? So if we show all the steps, it looks like this.” She then reworks the problem to make her point, justifying each step by giving a property of the rational numbers: Ms. Lawrence stops and looks at the students. As they do, Ms. Kaye asks them to explain what they are doing and why. Educational Studies in Mathematics, 20, 237–272. (NRC, 2001, Doyle, W. (1983). (1996). Otherwise, the practice can automatize incorrect procedures, which are then difficult to correct. Phi Delta Kappan, 76, 770–776. It also shapes both the task and students’ opportunities to learn from it. The five strands of Mathematical Proficiency Mathematical Proficiency is a term used by the authors of: Adding it up: helping children learn mathematics (NRC, 2001) to describe: “what it is to be successful in mathematics” Being mathematically proficient (numerate) means: 1. That understanding might have been developed in a variety of ways, but without it teaching the concept of a prime number would require simultaneously teaching about factors. For average-ability students, a small negative effect at fourth grade suggested that sustained use of calculators at that grade might hamper the acquisition of basic skills. “Let’s practice this a bit now and get it under our belts.” Mr. Angelo passes out a worksheet with 40 exercises that resemble what was done in class. 2). How she engages students requires active participation on their part, following closely her design for the lesson. He worries a bit, since the parents have been quite vocal in his school, with much pressure about getting students to algebra in eighth grade. Further, there is evidence that children’s collaborative interactions vary across social and cultural groups.45 For teachers to use cooperative groups effectively, they also need to select, organize, and present tasks that are well suited both to collaborative work and to the curriculum. Grouping by achievement level is more common in elementary and middle schools. Paper presented at the meeting of the American Educational Research Association, New Orleans. Good, T.L., & Brophy, J.E.
