Helping Teachers to Use and Students to Learn from Contrasting Examples: A Scale-up Study in Algebra I

Principal Investigator: 
Project Overview
Background & Purpose: 

We are designing and evaluating curriculum materials for an Algebra I course that draw upon the power of comparison - comparing and contrasting solution methods. After an initial period of materials development and piloting, we will conduct a randomized controlled trial to evaluate whether use of our materials positively impacts students' learning of algebra.

Research Design: 

The research design for this project is both longitudinal and comparative, and is designed to generate evidence which is descriptive [case study, design research and observational], and causal [experimental]. The intervention involves the use of curriculum materials and the comparison condition is business as usual, in a time series design.

This project collects original data using school records/policy documents, assessments of learning/achievement tests, observation [personal observation, videography, and web logs], and survey research including both paper and pencil, and online self completion questionnaire, as well as face-to-face semi-structured/informal interviews.

In Year 2, we will do qualitative analyses to understand the process of designing and implementing our materials. In Years 3-5, we will do HLM analyses on the quantitative data and complementary qualitative methods to understand how our materials did or did not work as intended.
