Project Activities
The researchers will develop a series of interventions that introduce an instructional innovation in mathematics teaching based on cognitive research: namely, perceptual learning, defined as "changes in the pick-up of information as a result of experience or practice." Recent research supports the claim that perceptual learning is especially effective in leading students to extract structural invariance across contextual variation, and to improve fluency, thus accelerating the development of expertise. The researchers will apply well-established principles of perceptual learning and recent research on perceptual learning in mathematics to improve students' math learning via computer-based learning modules coordinated with other modes of instruction.
Structured Abstract
Setting
The schools are located in California and in Pennsylvania.
Sample
The schools include culturally diverse student bodies with substantial numbers of children from low and moderate income families. The intervention will focus on students in Grades 3-8.
The researchers will develop a series of interventions that introduce an instructional innovation in mathematics teaching based on cognitive research: namely, perceptual learning, defined as "changes in the pick-up of information as a result of experience or practice." The researchers will develop and evaluate approximately six units of instructional materials that combine computer-based Perceptual Learning Modules, diagnostic assessments, benchmark lessons and investigations, and resources for teachers. The units are designed as supplemental materials to the classroom curriculum across several grade levels, and could be used flexibly in various combinations. Each unit includes a set of classroom lessons that introduces essential ideas (with teaching resources such as overhead transparencies and student pages included). These lessons connect to carefully targeted hands-on investigations in which students work in small groups engaging in quantitative reasoning to solve problems in measurement and fractions. Students also work individually on the corresponding computer-based Perceptual Learning Modules, which are aimed at achieving fluency in recognizing and discriminating key structures and relationships.
Research design and methods
Experimental studies will be conducted. Following pretest assessments, students will be assigned randomly to treatment and control conditions. Students assigned to perceptual learning treatment conditions will typically participate in two to six sessions working with a given Perceptual Learning Module. Following the instructional phase, immediate and delayed posttests are administered.
Control condition
Students in the control condition will receive the existing mathematics curriculum in the school.
Key measures
The researchers will rely primarily on three kinds of data to evaluate learning: (1) accuracy and speed (reaction time) data collected via the Perceptual Learning Modules, (2) diagnostic items derived from the research literature; and (3) items derived from standardized tests, such as NAEP items.
Data analytic strategy
The Perceptual Learning Modules software will allow individual learning profiles to be examined in detail (e.g., analyzing the shape of the learning curves for plateaus, inflection points, steady progress, and so forth). The researchers will also be able to compare characteristics of students who show strong, moderate, or weak learning gains. Within-subject analyses will allow them to systematically compare performance on different subtypes of items. Standard multivariate statistical methods (such as ANOVA) will allow them to look for main effects as well as interactions among factors, for both between-subject and within-subject variables.
