One of the most important lessons that I have learned as a teacher is that seemingly boring problems on paper can come alive if I can find a way to lift them off the page. This transformation took place when the number line in my classroom became a brightly colored rope that stretched the length of the room, held by a student at each end. I first saw this idea as an approach to help young children order numbers from 1 to 10, then adapted it for middle school students. The scope of the activity eventually expanded to include explorations of large numbers, rational numbers, and algebra. As I saw improvement in students' conceptual understanding and their enjoyment of the life-sized number line, I used it more often in my classroom. I also found that the activities with the number line involved communication, reasoning, and justification— important processes in learning mathematics (NCTM 1989, 2000).

The purpose of this study is to describe how analyzing student work can be used to help undergraduates reflect on the effectiveness of their service-learning experiences. The service-learning collaboration between a university and middle school was designed to increase undergraduates’ and middle school students’ knowledge of solar energy. Three undergraduates enrolled in a service-learning course that covered basic solar energy concepts and formative assessment instructional strategies. The focal point of the course was the implementation of several activities in a middle school classroom that addressed middle school students’ misconceptions about solar energy, such as the amount of solar energy production at low temperatures or on a cloudy day. Data from this study includes student work during a small-group activity on solar cells. Findings suggest that undergraduates can analyze student work and use this information to better understand how their efforts can influence middle school student learning of solar energy.

This department shares the thinking of middle school students as they explore and communicate mathematics. It will highlight students' work, including projects, investigations, or creative solutions to the problems in the monthly menu. Original student work will be included along with sufficient information about the activity so that readers can try the same ideas with their students. Please send articles and information for “The Thinking of Students” to the editor of the department: Karen Higgins, 28669 Royal Avenue, Eugene, OR 97402; home telephone (503) 688-1759. If readers need additional information, please include name, home address, home telephone number, and school name with the article. Please submit slides or photographs when possible. Submissions do not have to be in polished form, as the column can be written from the information the editor receives.

Numerous studies have demonstrated the relevance of magnitude estimation skills for mathematical proficiency, but little research has explored magnitude estimation with negative numbers. In two experiments the current study examined middle school students’ magnitude knowledge of negative numbers with number line tasks. In Experiment 1, both 6th (n = 132) and 7th grade students (n = 218) produced linear representations on a -10,000 to 0 scale, but the 7th grade students’ estimates were more accurate and linear. In Experiment 2, the 7th grade students also completed a -1,000 to 1,000 number line task; these results also indicated that students are linear for both negative and positive estimates. When comparing the estimates of negative and positive numbers, analyses illustrated that estimates of negative numbers are less accurate than those of positive numbers, but using a midpoint strategy improved negative estimates. These findings suggest that negative number magnitude knowledge follows a similar pattern to positive numbers, but the estimation performance of negatives lags behind that of positives.
