Empirical Education Publication Productivity


Empirical Education’s research group, led by Chief Scientist Andrew Jaciw, has been busy publishing articles that address key concerns of educators and researchers.

Our article describing the efficacy trial of Math in Focus program that was accepted by JREE earlier this year just arrived in print to our Palo Alto office a couple of weeks ago. If you subscribe to JREE, it’s the very first article in the current issue (volume 9, number 4). If you don’t subscribe, we have a copy in our lobby if anyone would like to stop by and check it out.

Another article that the analysis team has been working on is called “An Empirical Study of Design Parameters for Assessing Differential Impacts for Students in Group Randomized Trials.” This one has recently been accepted for publication in the Evaluation Review in the issue that should be printed any day now. The paper grows out of our work on many cluster randomized trials and our interest in differential impacts of programs. We believe that the question of “what works” has limited meaning without systematic exploration of “for whom” and “under what conditions”. The common perception is that these latter concerns are secondary and our designs have too little power to assess them. We challenge these notions and provide guidelines for addressing these questions.

In another issue of Evaluation Review, we published two companion articles:

Assessing the Accuracy of Generalized Inferences From Comparison Group Studies Using a Within-Study Comparison Approach: The Methodology


Applications of a Within-Study Comparison Approach for Evaluating Bias in Generalized Causal Inferences from Comparison Groups Studies

This work further extends our interest in issues of external validity and equip researchers with a strategy for testing the limits of generalizations from randomized trials. Written for a technical audience, the work extends an approach commonly used to assess levels of selection bias in estimates from non-experimental studies to examine bias in generalized inferences from experiments and non-experiments.

It’s always exciting for our team to share the findings from our experiments, as well as the things we learn during the analysis that can help the evaluation community provide more productive evidence for educators. Much of our work is done in partnership with other organizations and if you’re interested in partnering with us on this kind of work, please email Robin Means.

Math in Focus Paper Published in JREE

Chief Scientist Andrew Jaciw’s paper entitled Assessing Impacts of Math in Focus, a “Singapore Math” Program was accepted by the Journal of Research on Educational Effectiveness. The paper reports the results of an RCT conducted in Clark County (Las Vegas, NV) by a team that included Whitney Hegseth, Li Lin, Megan Toby, Denis Newman, Boya Ma, and Jenna Zacamy. From the abstract (available online here):

Twenty-two grade-level teams across twelve schools were randomized to the program or business as usual. Measures included indicators of fidelity to treatment, and student mathematics learning. Impacts on mathematics achievement ranged between .11 and .15 standard deviation units, with no differential impact based on level of pretest [or] minority status.

Conference Season 2015

Empirical researchers are traveling all over the country this conference season. Come meet our researchers as we discuss our work at the following events. If you plan to attend any of these, please get in touch so we can schedule a time to speak with you, or come by to see us at our presentations.

AEFP

We are pleased to announce that we will have our fifth appearance at the 40th annual conference of the Association for Education Finance and Policy (AEFP). Join us in the afternoon on Friday, February 27th at the Marriott Wardman Park, Washington DC as Empirical’s Senior Research Scientist Valeriy Lazarev and CEO Denis Newman present on Methods of Teacher Evaluation in Concurrent Session 7. Denis will also be the acting discussant and chair on Friday morning at 8am in Session 4.07 titled Preparation/Certification and Evaluation of Leaders/Teachers.

SREE

Attendees of this spring’s Society for Research on Effectiveness (SREE) Conference, held in Washington, DC March 5-7, will have the opportunity to discuss instructional strategies and programs to improve mathematics with Empirical Education’s Chief Scientist Andrew P. Jaciw. The presentation, Assessing Impacts of Math in Focus, a ‘Singapore Math’ Program for American Schools, will take place on Friday, March 6 at 1pm in the Park Hyatt Hotel, Ballroom Level Gallery 3.

ASCD

This year’s 70th annual conference for ASCD will take place in Houston, TX on March 21-23. We invite you to schedule a meeting with CEO Denis Newman while he’s there.

AERA

We will again be presenting at the annual meeting of the American Educational Research Association (AERA). Join the Empirical Education team in Chicago, Illinois from April 16-20, 2015. Our presentations will cover research under the Division H (Research, Evaluation, and Assessment in Schools) Section 2 symposium: Program Evaluation in Schools.

  1. Formative Evaluation on the Process of Scaling Up Reading Apprenticeship Authors: Jenna Lynn Zacamy, Megan Toby, Andrew P. Jaciw, and Denis Newman
  2. The Evaluation of Internet-based Reading Apprenticeship Improving Science Education (iRAISE) Authors: Megan Toby, Jenna Lynn Zacamy, Andrew P. Jaciw, and Denis Newman

We look forward to seeing you at our sessions to discuss our research. As soon as we have the schedule for these presentations, we will post them here. As has become tradition, we plan to host yet another of our popular AERA receptions. Details about the reception will follow in the months to come.

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.
