New Project with ALSDE to Study AMSTI

Empirical Education is excited to announce a new study of the Alabama Math, Science, and Technology Initiative (AMSTI) commissioned by the Alabama legislature. AMSTI is the Alabama State Department of Education’s initiative to improve math and science teaching statewide; the program, which started over 20 years ago and now operates in over 900 schools across the state, has been validated multiple times by external evaluators, including Empirical’s own 2012 study directed by Chief Scientist Andrew Jaciw. That cluster-randomized trial, which involved 82 schools and ~700 teachers, assessed the efficacy of AMSTI over a three year period and showed an overall positive effect (Newman et al., 2012).

The new study will use a quasi-experimental matched comparison group design and take advantage of existing data available from the Alabama State Department of Education and the AMSTI program. Schools using AMSTI will be compared to matched schools not using AMSTI to determine the impact of the program on math and science achievement for students in grades 3 through 8, as well as differential impacts of the program on important student subgroups. We will also make use of Improvement Science principles to examine school climates where the program may have greater or reduced impact.

At the conclusion of the study, Empirical Education’s report will be made available to select committees of the Alabama state legislature, the Governor and the Alabama State Board of Education, and the Alabama State Department of Education. Researchers from Empirical Education will also travel to Montgomery, Alabama to present the study findings and recommendations for improvement to the Alabama legislature.


Study Shows a “Singapore Math” Curriculum Can Improve Student Problem Solving Skills

A study of HMH Math in Focus (MIF) released today by research firm Empirical Education Inc. demonstrates a positive impact of the curriculum on Clark County School District elementary students’ math problem solving skills. The 2011-2012 study was contracted by the publisher, which left the design, conduct, and reporting to Empirical. MIF provides elementary math instruction based on the pedagogical approach used in Singapore. The MIF approach to instruction is designed to support conceptual understanding, and is said to be closely aligned with the Common Core State Standards (CCSS), which focuses more on in-depth learning than previous math standards.

Empirical found an increase in math problem solving among students taught with HMH Math in Focus compared to their peers. The Clark County School District teachers also reported an increase in their students’ conceptual understanding, as well as an increase in student confidence and engagement while explaining and solving math problems. The study addressed the difference between the CCSS-oriented MIF and the existing Nevada math standards and content. While MIF students performed comparatively better on complex problem solving skills, researchers found that students in the MIF group performed no better than the students in the control group on the measure of math procedures and computation skills. There was also no significant difference between the groups on the state CRT assessment, which has not fully shifted over to the CCSS.

The research used a group randomized control trial to examine the performance of students in grades 3-5 during the 2011-2012 school year. Each grade-level team was randomly assigned to either the treatment group that used MIF or the control group that used the conventional math curriculum. Researchers used three different assessments to capture math achievement contrasting procedural and problem solving skills. Additionally, the research design employed teacher survey data to conduct mediator analyses (correlations between percentage of math standards covered and student math achievement) and assess fidelity of classroom implementation.

Study of Alabama STEM Initiative Finds Positive Impacts

On February 21, 2012 the U.S. Department of Education released the final report of an experiment that Empirical Education has been working on for the last six years. The report, titled Evaluation of the Effectiveness of the Alabama Math, Science, and Technology Initiative (AMSTI) is now available on the Institute of Education Sciences website. The Alabama State Department of Education held a press conference to announce the findings, attended by Superintendent of Education Bice, staff of AMSTI, along with educators, students, and co-principal investigator of the study, Denis Newman, CEO of Empirical Education. The press release issued by the Alabama State Department of Education and a WebEx presentation provide more detail on the study’s findings.

AMSTI was developed by the state of Alabama and introduced in 2002 with the goal of improving mathematics and science achievement in the state’s K-12 schools. Empirical Education was primarily responsible for conducting the study—including the design, data collection, analysis, and reporting—under its subcontract with the Regional Education Lab, Southeast (the study was initiated through a research grant to Empirical). Researchers from Academy of Education Development, Abt Associates, and ANALYTICA made important contributions to design, analysis and data collection.

The findings show that after one year, students in the 41 AMSTI schools experienced an impact on mathematics achievement equivalent to 28 days of additional student progress over students receiving conventional mathematics instruction. The study found, after one year, no difference for science achievement. It also found that AMSTI had an impact on teachers’ active learning classroom practices in math and science that, according to the theory of action posited by AMSTI, should have an impact on achievement. Further exploratory analysis found effects for student achievement in both mathematics and science after two years. The study also explored reading achievement, where it found significant differences between the AMSTI and control groups after one year. Exploration of differential effect for student demographic categories found consistent results for gender, socio-economic status, and pretest achievement level for math and science. For reading, however, the breakdown by student ethnicity suggests a differential benefit.

Just about everybody at Empirical worked on this project at one point or another. Besides the three of us (Newman, Jaciw and Zacamy) who are listed among the authors, we want to acknowledge past and current employees whose efforts made the project possible: Jessica Cabalo, Ruthie Chang, Zach Chin, Huan Cung, Dan Ho, Akiko Lipton, Boya Ma, Robin Means, Gloria Miller, Bob Smith, Laurel Sterling, Qingfeng Zhao, Xiaohui Zheng, and Margit Zsolnay.

With solid cooperation of the state’s Department of Education and the AMSTI team, approximately 780 teachers and 30,000 upper-elementary and middle school students in 82 schools from five regions in Alabama participated in the study. The schools were randomized into one of two categories: 1) Those who received AMSTI starting the first year, or 2) Those who received “business as usual” the first year and began participation in AMSTI the second year. With only a one-year delay before the control group entered treatment, the two-year impact was estimated using statistical techniques developed by, and with the assistance of our colleagues at Abt Associates. Academy for Education Development assisted with data collection and analysis of training and program implementation.

Findings of the AMSTI study will also be presented at the Society for Research on Educational Effectiveness (SREE) Spring Conference taking place in Washington D.C. from March 8-10, 2012. Join Denis Newman, Andrew Jaciw, and Boya Ma on Friday March 9, 2012 from 3:00pm-4:30pm, when they will present findings of their study titled, “Locating Differential Effectiveness of a STEM Initiative through Exploration of Moderators.” A symposium on the study, including the major study collaborators, will be presented at the annual conference of the American Educational Research Association (AERA) on April 15, 2012 from 2:15pm-3:45pm at the Marriott Pinnacle ⁄ Pinnacle III in Vancouver, Canada. This session will be chaired by Ludy van Broekhuizen (director of REL-SE) and will include presentations by Steve Ricks (director of AMSTI); Jean Scott (SERVE Center at UNCG); Denis Newman, Andrew Jaciw, Boya Ma, and Jenna Zacamy (Empirical Education); Steve Bell (Abt Associates); and Laura Gould (formerly of AED). Sean Reardon (Stanford) will serve as the discussant. A synopsis of the study will also be included in the Common Guidelines for Education Research and Development.


Report completed on the effectiveness of MathForward

Empirical Education assisted Richardson Independent School District (RISD) in conducting an evaluation of the MathForward algebra readiness program published by Texas Instruments. RISD implemented MathForward in their 7th and 8th grade general mathematics and 9th grade Algebra I classes. The research employed an interrupted time series design comparing existing student achievement scores with MathForward to student achievement scores from the three years prior to the introduction of MathForward.

The results of this four-year study suggest that 7th grade students scored, on average, 11 percentile points higher with MathForward than the 7th grade students from the three previous years without MathForward. A similar result for the 8th grade suggests that students participating in MathForward scored, on average, 9 percentile points higher. While the trend did not hold for 9th grade, further exploration suggests that 9th grade students whose teachers had 3 years experience using MathForward scored higher than 9th grade students whose teachers did not use MathForward.

The report further illustrates how an interrupted time series design can be used to study a program as it is rolled out over several years. This research will be presented at the 2010 AERA conference in Denver, Colorado (Friday, April 30 — Tuesday, May 4).

Two-Year Study on Effectiveness of Graphing Calculators Released

Results are in from a two-year randomized control trial on the effectiveness of graphing calculators on Algebra and Geometry achievement. Two reports are now available for this project, which was sponsored by Texas Instruments. In year 1 we contrasted business as usual in the math classes of two California school districts with classes equipped with sets of graphing calculators and led by teachers who received training in their use. In the second year we contrasted calculator-only classrooms with those also equipped with a calculator-based wireless networking system.

The project tracked achievement through state and other standardized test scores and implementation through surveys and observations. For the most part, the experiment could not discern an impact as a result of providing the equipment and training for the teachers. Data from surveys and observations make clear that the technology was not used extensively (and by some, not at all) suggesting that training, usability, and alignment issues must be addressed in adoption of this kind of program. There were modest effects, especially for Geometry, but these were often not found consistently for the two measurement scales. In one case contradictory results for the two school districts suggests that researchers should use caution in combining data from different settings.
