IES Published Our REL Southwest Study on Trends in Teacher Mobility

The U.S. Department of Education’s Institute of Education Sciences published a report of a study we conducted for REL Southwest! We are thankful for the support and engagement we received from the Educator Effectiveness Research Alliance throughout the study.

The study was published in December 2017 and provides updated information regarding teacher mobility for Texas public schools during the 2011-12 through 2015-16 school years. Teacher mobility is defined as teachers changing schools or leaving the public school system.

In the report, descriptive information on mobility rates is presented at the regional and state levels for each school year. Mobility rates are disaggregated further into destination proportions to describe the proportion of teacher mobility due to within-district movement, between-district movement, and leaving Texas public schools. This study leverages data collected by the Texas Education Agency during the pilot of the Texas Teacher Evaluation and Support System (T-TESS) in 57 school districts in 2014-15. Analyses examine how components of the T-TESS observation rubric are related to school-level teacher mobility rates.

During the 2011-12 school year, 18.7% of Texas teachers moved schools within a district, moved between districts, or left the Texas Public School system. By 2015-16, this mobility rate had increased to 22%. Moving between districts was the primary driver of the increase in mobility rates. Results indicate significant links between mobility and teacher, student, and school demographic characteristics. Teachers with special education certifications left Texas public schools at nearly twice the rate of teachers with other teaching certifications. School-level mobility rates showed significant positive correlations with the proportion of special education, economically disadvantaged, low-performing, and minority students. School-level mobility rates were negatively correlated with the proportion of English learner students. Schools with higher overall observation ratings on the T-TESS rubric tended to have lower mobility rates.

Findings from this study will provide state and district policymakers in Texas with updated information about trends and correlates of mobility in the teaching workforce, and offer a systematic baseline for monitoring and planning for future changes. Informed by these findings, policymakers can formulate a more strategic and targeted approach for recruiting and retaining teachers. For instance, instead of using generic approaches to enhance the overall supply of teachers or improve recruitment, more targeted efforts to attract and retain teachers in specific subject areas (for example, special education), in certain stages of their career (for example, novice teachers), and in certain geographic areas are likely to be more productive. Moreover, this analysis may enrich the existing knowledge base about schools’ teacher retention and mobility in relation to the quality of their teaching force, or may inform policy discussions about the importance of a stable teaching force for teaching effectiveness.

IES Publishes our Recent REL Southwest Teacher Studies

The U.S. Department of Education’s Institute of Education Sciences published two reports of studies we conducted for REL Southwest! We are thankful for the support and engagement we received from the Educator Effectiveness Research Alliance and the Oklahoma Rural Schools Research Alliance throughout the studies. The collaboration with the research alliances and educators aligns well with what we set out to do in our core mission: to support K-12 systems and empower educators in making evidence-based decisions.

The first study was published earlier this month and identified factors associated with successful recruitment and retention of teachers in Oklahoma rural school districts, in order to highlight potential strategies to address Oklahoma’s teaching shortage. This correlational study covered a 10-year period (the 2005-06 to 2014-15 school years) and used data from the Oklahoma State Department of Education, the Oklahoma Office of Educational Quality and Accountability, federal non-education sources, and publicly available geographic information systems from Google Maps. The study found that teachers who are male, those who have higher postsecondary degrees, and those who have more teaching experience are harder than others to recruit and retain in Oklahoma schools. In addition, for teachers in rural districts, higher total compensation and increased responsibilities in job assignment are positively associated with successful recruitment and retention. In order to provide context, the study also examined patterns of teacher job mobility between rural and non-rural school districts. The rate of teachers in Oklahoma rural schools reaching tenure is slightly lower than the rates for teachers in non-rural areas. Also, rural school districts in Oklahoma had consistently lower rates of success in recruiting teachers than non-rural school districts from 2006-07 to 2011-12.

This most recent study, published last week, examined data from the 2014-15 pilot implementation of the Texas Teacher Evaluation and Support System (T-TESS). In 2014-15 the Texas Education Agency piloted the T-TESS in 57 school districts. During the pilot year teacher overall ratings were based solely on rubric ratings on 16 dimensions across four domains.

The study examined the statistical properties of the T-TESS rubric to explore the extent to which it differentiates teachers on teaching quality and to investigate its internal consistency and efficiency. It also explored whether certain types of schools have teachers with higher or lower ratings. Using data from the pilot for more than 8,000 teachers, the study found that the rubric differentiates teacher effectiveness at the overall, domain, and dimension levels; domain and dimension ratings on the observation rubric are internally consistent; and the observation rubric is efficient, with each dimension making a unique contribution to a teacher’s overall rating. In addition, findings indicated that T-TESS rubric ratings varied slightly in relation to some school characteristics that were examined, such as socioeconomic status and percentage of English Language Learners. However, there is little indication that these characteristics introduced bias in the evaluators’ ratings.

Report of the Evaluation of iRAISE Released

Empirical Education Inc. has completed its evaluation (read the report here) of an online professional development program for Reading Apprenticeship. WestEd’s Strategic Literacy Initiative (SLI) was awarded a development grant under the Investing in Innovation (i3) program in 2012. iRAISE (internet-based Reading Apprenticeship Improving Science Education) is an online professional development program for high school science teachers. iRAISE trained more than 100 teachers in Michigan and Pennsylvania over the three years of the grant. Empirical’s randomized control trial measured the impact of the program on students with special attention to differences in their incoming reading achievement levels.

The goal of iRAISE was to improve student achievement by training teachers in the use of Reading Apprenticeship, an instructional framework that describes the classroom in four interacting dimensions of learning: social, personal, cognitive, and knowledge-building. The inquiry-based professional development (PD) model included a week-long Foundations training in the summer; monthly synchronous group sessions and smaller personal learning communities; and asynchronous discussion groups designed to change teachers’ understanding of their role in adolescent literacy development and to build capacity for literacy instruction in the academic disciplines. iRAISE adapted an earlier face-to-face version of Reading Apprenticeship professional development, which was studied under an earlier i3 grant, Reading Apprenticeship Improving Secondary Education (RAISE), into a completely online course, creating a flexible, accessible platform.

To evaluate iRAISE, Empirical Education conducted an experiment in which 82 teachers across 27 schools were randomly assigned to either receive the iRAISE Professional Development during the 2014-15 school year or continue with business as usual and receive the program one year later. Data collection included monthly teacher surveys that measured their use of several classroom instructional practices and a spring administration of an online literacy assessment, developed by Educational Testing Service, to measure student achievement in literacy. We found significant positive impacts of iRAISE on several of the classroom practice outcomes, including teachers providing explicit instruction on comprehension strategies, their use of metacognitive inquiry strategies, and their levels of confidence in literacy instruction. These results were consistent with the prior RAISE research study and are an important replication of the previous findings, as they substantiate the success of SLI’s development of a more accessible online version of their teacher PD. After a one-year implementation with iRAISE, we do not find an overall effect of the program on student literacy achievement. However, we did find that levels of incoming reading achievement moderate the impact of iRAISE on general reading literacy such that lower scoring students benefit more. The success of iRAISE in adapting immersive, high-quality professional development to an online platform is promising for the field.

Five-year evaluation of Reading Apprenticeship i3 implementation reported at SREE

Empirical Education has released two research reports on the scale-up and impact of Reading Apprenticeship, as implemented under one of the first cohorts of Investing in Innovation (i3) grants. The Reading Apprenticeship Improving Secondary Education (RAISE) project reached approximately 2,800 teachers in five states with a program providing teacher professional development in content literacy in three disciplines: science, history, and English language arts. RAISE supported Empirical Education and our partner, IMPAQ International, in evaluating the innovation through both a randomized control trial encompassing 42 schools and a systematic study of the scale-up of 239 schools. The RCT found significant impact on student achievement in science classes consistent with prior studies. Mean impact across subjects, while positive, did not reach the .05 level of significance. The scale-up study found evidence that the strategy of building cross-disciplinary teacher teams within the school is associated with growth and sustainability of the program. Both sides of the evaluation were presented at the annual conference of the Society for Research on Educational Effectiveness, March 6-8, 2016 in Washington DC. Cheri Fancsali (formerly of IMPAQ, now at Research Alliance for NYC Schools) presented results of the RCT. Denis Newman (Empirical) presented a comparison of RAISE as instantiated in the RCT and scale-up contexts.

Evaluation Concludes Aspire’s PD Tools Show Promise to Impact Classroom Practice

Empirical Education Inc. has completed an independent evaluation (read the report here) of a set of tools and professional development opportunities developed and implemented by Aspire Public Schools under an Investing in Innovation (i3) grant. Aspire was awarded the development grant in the 2011 funding cycle and put the system, Transforming Teacher Talent (t3), into operation in 2013 in their 35 California schools. The goal of t3 was to improve teacher practice as measured by the Aspire Instructional Rubric (AIR) and thereby improve student outcomes on the California Standards Test (CST), the state assessment. Some of the t3 components connected the AIR scores from classroom observations to individualized professional development materials building on tools from BloomBoard, Inc.

To evaluate t3, Empirical principal investigator, Andrew Jaciw and his team designed the strongest feasible evaluation. Since it was not possible to split the schools into two groups by having two versions of Aspire’s technology infrastructure supporting t3, a randomized experiment or other comparison group design was not feasible. Working with the National Evaluation of i3 (NEi3) team, Empirical developed a correlational design comparing two years of teacher AIR scores and student CST scores; that is, from the 2012-13 school year to the scores in the first year of implementation, 2013-14. Because the state was in a transition to new Common Core tests, the evaluation was unable to collect student outcomes systematically. The AIR scores, however, provided evidence of substantial overall improvement with an effect size of 0.581 standard deviations (p <.001). The evidence meets the standards for “evidence-based” as defined in the recently enacted Every Student Succeeds Act (ESSA), which requires, at the least, that the test of the intervention “demonstrates a statistically significant effect on improving…relevant outcomes based on…promising evidence from at least 1 well designed and well-implemented correlational study with statistical controls for selection bias.” A demonstration of promise can assist in obtaining federal and other funding.

IES Releases New Empirical Education Report on Educator Effectiveness

Just released by IES, our report examines the statistical properties of Arizona’s new multiple-measure teacher evaluation model. The study used data from the pilot in 2012-13 to explore the relationships among the system’s component measures (teacher observations, student academic progress, and stakeholder surveys). It also investigated how well the model differentiated between higher and lower performing teachers. Findings suggest that the model’s observation measure may be improved through further evaluator training and calibration, and that a single aggregated composite score may not adequately represent independent aspects of teacher performance.

The study was carried out in partnership with the Arizona Department of Education as part of our work with the Regional Education Laboratory (REL) West’s Educator Effectiveness Alliance, which includes Arizona, Utah, and Nevada Department of Education officials, as well as teacher union representatives, district administrators, and policymakers. While the analysis is specific to Arizona’s model, the study findings and methodology may be of interest to other state education agencies that are developing of implementing new multiple-measure evaluation systems. We have continued this work with additional analyses for alliance members and plan to provide additional capacity building during 2015.

The Value of Looking at Local Results

The report we released today has an interesting history that shows the value of looking beyond the initial results of an experiment. Later this week, we are presenting a paper at AERA entitled “In School Settings, Are All RCTs Exploratory?” The findings we report from our experiment with an iPad application were part of the inspiration for this. If Riverside Unified had not looked at its own data, we would not, in the normal course of data analysis, have broken the results out by individual districts, and our conclusion would have been that there was no discernible impact of the app. We can cite many other cases where looking at subgroups leads us to conclusions different from the conclusion based on the result averaged across the whole sample. Our report on AMSTI is another case we will cite in our AERA paper.

We agree with the Institute of Education Sciences (IES) in taking a disciplined approach in requiring that researchers “call their shots” by naming the small number of outcomes considered most important in any experiment. All other questions are fine to look at but fall into the category of exploratory work. What we want to guard against, however, is the implication that answers to primary questions, which often are concerned with average impacts for the study sample as a whole, must apply to various subgroups within the sample, and therefore can be broadly generalized by practitioners, developers, and policy makers.

If we find an average impact but in exploratory analysis discover plausible, policy-relevant, and statistically strong differential effects for subgroups, then some doubt about completeness may be cast on the value of the confirmatory finding. We may not be certain of a moderator effect—for example—but once it comes to light, the value of the average impact can also be considered incomplete or misleading for practical purposes. If it is necessary to conduct an additional experiment to verify a differential subgroup impact, the same experiment may verify that the average impact is not what practitioners, developers, and policy makers should be concerned with.

In our paper at AERA, we are proposing that any result from a school-based experiment should be treated as provisional by practitioners, developers, and policy makers. The results of RCTs can be very useful, but the challenges of generalizability of the results from even the most stringently designed experiment mean that the results should be considered the basis for a hypothesis that the intervention may work under similar conditions. For a developer considering how to improve an intervention, the specific conditions under which it appeared to work or not work is the critical information to have. For a school system decision maker, the most useful pieces of information are insight into subpopulations that appear to benefit and conditions that are favorable for implementation. For those concerned with educational policy, it is often the case that conditions and interventions change and develop more rapidly than research studies can be conducted. Using available evidence may mean digging through studies that have confirmatory results in contexts similar or different from their own and examining exploratory analyses that provide useful hints as to the most productive steps to take next. The practitioner in this case is in a similar position to the researcher considering the design of the next experiment. The practitioner also has to come to a hypothesis about how things work as the basis for action.

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.

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.

Exploration in the World of Experimental Evaluation

Our 300+ page report makes a good start. But IES, faced with limited time and resources to complete the many experiments being conducted within the Regional Education Lab system, put strict limits on the number of exploratory analyses researchers could conduct. We usually think of exploratory work as questions to follow up on puzzling or unanticipated results. However, in the case of the REL experiments, IES asked researchers to focus on a narrow set of “confirmatory” results and anything else was considered “exploratory,” even if the question was included in the original research design.

The strict IES criteria were based on the principle that when a researcher is using tests of statistical significance, the probability of erroneously concluding that there is an impact when there isn’t one increases with the frequency of the tests. In our evaluation of AMSTI, we limited ourselves to only four such “confirmatory” (i.e., not exploratory) tests of statistical significance. These were used to assess whether there was an effect on student outcomes for math problem-solving and for science, and the amount of time teachers spent on “active learning” practices in math and in science. (Technically, IES considered this two sets of two, since two were the primary student outcomes and two were the intermediate teacher outcomes.) The threshold for significance was made more stringent to keep the probability of falsely concluding that there was a difference for any of the outcomes at 5% (often expressed as p < .05).

While the logic for limiting the number of confirmatory outcomes is based on technical arguments about adjustments for multiple comparisons, the limit on the amount of exploratory work was based more on resource constraints. Researchers are notorious (and we don’t exempt ourselves) for finding more questions in any study than were originally asked. Curiosity-based exploration can indeed go on forever. In the case of our evaluation of AMSTI, however, there were a number of fundamental policy questions that were not answered either by the confirmatory or by the exploratory questions in our report. More research is needed.

Take the confirmatory finding that the program resulted in the equivalent of 28 days of additional math instruction (or technically an impact of 5% of a standard deviation). This is a testament to the hard work and ingenuity of the AMSTI team and the commitment of the school systems. From a state policy perspective, it gives a green light to continuing the initiative’s organic growth. But since all the schools in the experiment applied to join AMSTI, we don’t know what would happen if AMSTI were adopted as the state curriculum requiring schools with less interest to implement it. Our results do not generalize to that situation. Likewise, if another state with different levels of achievement or resources were to consider adopting it, we would say that our study gives good reason to try it but, to quote Lee Cronbach, a methodologist whose ideas increasingly resonate as we translate research into practice: “…positive results obtained with a new procedure for early education in one community warrant another community trying it. But instead of trusting that those results generalize, the next community needs its own local evaluation” (Cronbach, 1975, p. 125).

The explorations we conducted as part of the AMSTI evaluation did not take the usual form of deeper examinations of interesting or unexpected findings uncovered during the planned evaluation. All the reported explorations were questions posed in the original study plan. They were defined as exploratory either because they were considered of secondary interest, such as the outcome for reading, or because they were not a direct causal result of the randomization, such as the results for subgroups of students defined by different demographic categories. Nevertheless, exploration of such differences is important for understanding how and for whom AMSTI works. The overall effect, averaging across subgroups, may mask differences that are of critical importance for policy

Readers interested in the issue of subgroup differences can refer to Table 6.11. Once differences are found in groups defined in terms of individual student characteristics, our real exploration is just beginning. For example, can the difference be accounted for by other characteristics or combinations of characteristics? Is there something that differentiates the classes or schools that different students attend? Such questions begin to probe additional factors that can potentially be addressed in the program or its implementation. In any case, the report just released is not the “final report.” There is still a lot of work necessary to understand how any program of this sort can continue to be improved.

Final Report Released on The Efficacy of PCI’s Reading Program

Empirical has released the final report of a three-year longitudinal study on the efficacy of the PCI Reading Program, which can be found on our reports page. This study, the first formal assessment of the PCI Reading Program, evaluated the program among a sample of third- through eighth-grade students with supported-level disabilities in Florida’s Brevard Public Schools and Miami-Dade County Public Schools. The primary goal of the study was to identify whether the program could achieve its intended purpose of teaching specific sight words. The study was completed in three “phases,” or school years. The results from Phase 1 and 2 showed a significant positive effect on student sight word achievement and Phase 2 supported the initial expectation that two years of growth would be greater than one year (read more on results of Phase 1 and Phase 2).

“Working with Empirical Education was a win for us on many fronts. Their research was of the highest quality and has really helped us communicate with our customers through their several reports and conference presentations. They went beyond just outcomes to show how teachers put our reading program to use in classrooms. In all their dealings with PCI and with the school systems they were highly professional and we look forward to future research partnership opportunities.” - Lee Wilson, President & CEO, PCI Educational Publishing

In Phase 3, the remaining sample of students was too small to conduct any impact analyses, so researchers investigated patterns in students’ progress through the program. The general findings were positive in that the exploration confirmed that students continue to learn more sight words with a second year of exposure to PCI although at a slower pace than expected by the developers. Furthermore, findings across all three phases show high levels of teacher satisfaction with the program. Along with this positive outcome, teacher-reported student engagement levels were also high.
