Low Achievers May Benefit from Interactive Mathematics December 2006
Students with special learning needs require alternative forms of assessment that allow them to express all they know and can do. Without these accommodations, teachers can’t accurately measure student learning. In a recent study, lowachieving students in mathematics made slightly larger gains on a multimedia computerbased assessment than on a traditional pencilandpaper assessment. This suggests that the multimedia test may have accommodated at least some special needs of these students. Constructivist Approach. . . What is it?
UWMadison education professor Brian Bottge and colleague Enrique Rueda developed and evaluated the effectiveness of a multimedia computerbased assessment in a recent study of 109 seventhgrade students and their two math teachers. Students in each of the six classes were randomly assigned to either a computerbased assessment or a paperandpencil assessment. Bottge had developed a multimedia EAI problem called Fraction of the Cost, which had been integrated into the school’s math curriculum the year before. Bottge developed Fraction of the Cost to address the knowledge and concepts in the National Council of Teachers of Mathematics (NCTM) Standards recommended for students in grades 68. Fraction of the Cost includes an 8minute video presentation, or anchor. It stars three local middle school students. In the video, they visit a skateboard store and discuss how they can afford to buy materials for building a skateboard ramp. To solve the problem, students need to (a) calculate the percent of money in a savings account and sales tax on a purchase, (b) read a tape measure, (c) convert feet to inches, (d) decipher building plans, (e) construct a table of materials, (f) compute whole numbers and mixed fractions, (g) estimate and compute combinations, and (h) calculate total cost. After students in the math class view this video they describe the mathematics problems involved, then work in small groups. The teacher then assesses the students’ learning either with the computerbased assessment (CBA) or the paperandpencil based assessment (PPA). Each assessment contains constructedresponse items (see below) that measure the concepts in Faction of the Cost. The CBA measures the same concepts as the PPA, with the additional benefit of providing students a level of interactivity similar to what they had experienced in the contextualized authenticlike problems in EAI. Bottge anticipated that the new test would especially benefit the lowachieving students: They could access information for solving the EAI problem on the test rather than having to recall the relevant information from the instructional period. To identify differences in students’ problemsolving strategies, Bottge recorded and measured students’ search paths as they worked on the CBA. Bottge predicted that the CBA would eliminate some of the cognitive demands of problems for the lowachieving students and would thus enable them to more fully demonstrate their understanding of the math concepts they had learned. That seems to have happened. The study showed that low achievers made slightly larger gains on the CBA than on the PPA. This research provides a first step in developing multimediabased assessments that can match the contextualized nature of Enhanced Anchored Instruction. The accommodations provided by more flexible test formats may have the potential to more adequately assess deeper understandings of students with poor language skills. In future work Bottge expects to merge interactive assessments as used in this study with interactive instructional tools to provide formative measures of student skills. The aim is to help teachers individualize instruction and to help them evaluate the effectiveness of curricular materials and instructional practices.
