Research in Mathematics Education
ELM is funded by the Institute of Education Sciences. The goal of ELM is to study of an innovative kindergarten mathematics instructional program designed to improve early numeracy and prevent later math difficulties. This project was implemented in 67 classrooms in Dallas, and impacted the mathematics development of approximately 1,675 students. Data collection on this project ended in spring 2011.
This study examined the efficacy of a kindergarten math curriculum, ELM. The ELM curriculum is a comprehensive mathematics curriculum consisting of 120 lessons providing explicit instruction in (a) number operations, (b) geometry, (c) measurement, and (d) vocabulary. ELM is designed to address the learning needs of all students including at-risk students in the general education or tier 1 classroom setting. The study utilized a randomized block design, with classrooms assigned within schools to treatment and control. Sixty-four kindergarten classrooms stratified by region were randomly assigned within school to treatment (ELM) or control (standard district practices in kindergarten mathematics instruction) conditions. Proximal and distal measures of mathematics achievement were collected at pretest and posttest to measure student achievement.

The purpose of this SMU funded research project is to examine the appropriateness of innovative item designs for accurately measuring student knowledge and skills in algebra. Items are designed using the principles of universal design for assessment as well as emerging theories about accommodations to support students with disabilities.
The purpose of this project is to design, develop, and implement a prototype of a maximally accessible assessment system in mathematics. We embed principles of universal design in the development of a middle-school math test targeting algebra skills. We pilot test the items to evaluate item functioning and conduct an experimental study to investigate the comparability of scores under standard and universally designed formats for students with and without disabilities.
