Presenters: Laura M. Stapleton and Yating Zheng, University of Maryland, College Park


Topic: Value Added Modeling and Alternate Approaches for Ranking Institutions


Presentation Abstract: One of the research questions on the MLDS research agenda is “Which 4-year institutions are graduating students most effectively and in the timeliest fashion?” Typically, an analysis referred to as value-added modeling (VAM) is used to address this type of question. However, VAM has been criticized in its use to rank institutions and teachers. In this talk, value-added modeling will be defined and its assumptions delineated. We will propose an alternate approach, one that utilizes propensity score methods to rank institutions within a set of institutions with some similar student characteristics (e.g., high school attendance). Workforce outcomes will be examined for students within institutions. A proof-of-concept analysis will be presented and the audience will be asked for feedback and ideas.

Topic: Investigating the “Brain-Drain” Phenomenon in Maryland


Presentation Abstract: Upon graduation from secondary school, students may follow one of three possible paths. They may enroll in a post-secondary educational institution within their state of residence; they may enroll in a post-secondary educational institution outside their state; or they may go on to activities other than post-secondary education, such as entering the workforce or military service. An ongoing goal for many states is to increase the proportion of in-state high school students who go on to attend in-state post-secondary educational institutions. A major driving force behind this goal is the concern that students who attend out-of-state institutions are less likely to return to seek employment in their original state of residence following graduation, and thus are less likely to contribute to the state’s economy and workforce quality. This occurrence is popularly known as “brain-drain.” There is as yet little evidence to evaluate how substantial this type of “brain-drain” may be. We address this gap in knowledge using data from the Maryland Longitudinal Data System (MLDS) to investigate employment information for Maryland public high school graduates who go on to attend an in-state post-secondary educational institution versus an out-of-state institution.

Topic: Need-based Grant Aid in Higher Education: The Effects of the Howard P. Rawlings Educational Assistance (EA) Grant on Financial Aid, Academic Persistence, and Working while in School


Presentation Abstract: This presentation will showcase preliminary findings on the effects of the Howard P. Rawlings Educational Assistance (EA) Grant, the State of Maryland’s largest need-based grant program, on several student outcomes. Data from the Maryland Longitudinal Data System (MLDS) will be used to examine the strict eligibility cutoff for the grant as an identification strategy. A regression discontinuity approach will be used to investigate how receipt of the grant affects a student’s overall financial aid package, including grants from other sources and student loans. Using earnings data, it also examines whether students respond to grant aid by earning less in wages. Finally, the research estimates the effect of the EA grant on postsecondary persistence and degree receipt, and whether these effects differ by student income and high school characteristics.

Topic: Dual Enrollment in Maryland: Highlights from the 2016 Dual Enrollment Report


Presentation Abstract: This presentation will highlight findings from the Maryland Longitudinal Data System Center’s annual report on dually enrolled students, which is a requirement of the College and Career Readiness and College Completion Act (CCR-CCA) of 2013. As defined in Education Article §18-14A-01, Annotated Code of Maryland, a dually enrolled student is a student who is enrolled in both a secondary school (high school) and an institution of higher education (college) in Maryland. Data from the Maryland Longitudinal Data System (MLDS) were used to identify students who (1) had overlapping enrollment dates in a Maryland public high school and a Maryland college and (2) were enrolled in the college for at least 30 days. Findings on the rates and trends in dual enrollment, the courses in which students were dually enrolled, and the college enrollment outcomes of dually enrolled students will be presented.

Topic: Postsecondary College and Workforce Outcomes for Baltimore City Graduates


Presentation Abstract: Data from the Maryland Longitudinal Data System (MLDS) were used to examine the wages earned and industries employing Maryland high school diploma earners, certificate of completion earners, diploma earners via the GED program, and high school non-completers. For the population of students who did not enroll in college, wage outcomes were calculated using two methods: (1) annualized wages and (2) four-quarter wages. Annualized wages were calculated by dividing the total amount of wages earned in the year by the number of quarters worked and multiplying by four. This method retains all individuals who earned any amount of wages during the year. Four-quarter wages were calculated by summing all four-quarters of wages. This method retains only individuals who had wages for all four quarters within the year. Results using the two methods will be compared and discussed.

Topic: Postsecondary College and Workforce Outcomes for Baltimore City Graduates


Presentation Abstract: Baltimore’s Promise (BP) is a city-wide partnership of public agencies, foundations, businesses and non-profit organizations that seeks to coordinate resources to promote better outcomes for Baltimore’s children and young adults. The Maryland Longitudinal Data System (MLDS) is one important partner to BP, as it collects and links critical data that can speak to many of its target goals. From the Baltimore Education Research Consortium, another research partner to BP, Drs. Durham and Connolly will share preliminary findings from analyses of MLDS data on college enrollment, persistence, degree completion, workforce attachment and earnings of Baltimore graduates from the Classes of 2008 through 2015. While their presentation will raise many more questions than it can answer in one hour, the authors hope to use these baseline findings to generate compelling future avenues for research on the well-being of Baltimore youth. Please come be a part of this conversation!

Topic: STEM Workforce Preparation and Retention in Maryland


Presentation Abstract: This presentation will begin with an overview of what the STEM education and workforce includes and the current state of that workforce. Then analyses of the data housed in the Maryland Longitudinal Data System Center (MLDSC) will be used to detail first year workforce wage outcomes for postsecondary students in Maryland who earned degrees in STEM related disciplines. Those degree earners included graduates from the 2008-2009 to the 2012-2013 academic years. The retention patterns of those postsecondary STEM graduates will also be presented.

Topic: High School Graduation in Context: An Investigation into the Individual and School-level Factors Related to On-Time Graduation in Baltimore City


Presentation Abstract: Over the past decade national data have described consistent improvements in reducing dropout and increasing graduation rates culminating in a record high four-year graduation rate of 81.4% in 2013 (Kena et al., 2015). This has been attributed in large part to reductions in disparities for minority students and reductions in dropout rates for students in large urban school districts such as Baltimore (DiPaoli et al., 2015). Although this reduction in dropouts is a positive trend, there is an increasing group of students who persist into and through four years of high school without earning a diploma (Kena et al., 2015; Maryland State Department of Education [MSDE], 2015). This talk explores this growing population of students, with the goal of informing policy, programming, and practice in order to promote on-time graduation, preparation for the workforce, and post-secondary readiness.

Topic: Dual Enrollment in Maryland: Using Data from the Maryland Longitudinal Data System to Examine Trends, Demographics, and Outcomes


Presentation Abstract: Dual enrollment, which in Maryland refers to enrollment in a secondary school in the State and an institution of higher education in the State, has the potential to improve student educational access and outcomes. The primary aim of this presentation is to detail what is known about dual enrollment in Maryland using cross-agency data from the Maryland Longitudinal Data System. Longitudinal trends in the number of students dually enrolled, the characteristics of students dually enrolled, and the postsecondary enrollment outcomes of students dually enrolled will be presented. A discussion will focus on implications for future research and policy.

Presenters: Dr. Laura Stapleton, MLDS Research Branch


Topic: Expanding MLDS Data Access and Research Capacity with Synthetic Data Sets


Presentation Abstract: The Center has an obligation to make data accessible to researchers, policy makers, and stakeholders. However, a constellation of state and federal confidentiality laws and policies including the statute that created the MLDSC, limits the ability of the Center to provide even de-identified raw data sets to researchers outside of the Center staff and officially affiliated researchers. As part of the 2015 State Longitudinal Data Systems Grants recently announced by the U.S. Department of Education, the State of Maryland has been awarded approximately $2.6 million to create a synthetic data system. In this talk, we will describe what synthetic data are and the challenges that we will face in the creation of the system. In this talk, the presenters will describe what synthetic data are and the challenges that they will face in the creation of the system. They will also identify considerations surrounding the creation of the system that require input from possible end users from the research community. This Research Series presentation and the discussion to follow initiate this first step in system creation.

Presenters: Mr. Daniel McNeish, Research Analyst, MLDS Research Branch


Topic: Clustered Data - Are Multilevel Models Really Necessary?


Presentation Abstract: In educational research, multilevel models (MLMs) are a popular method for modeling data that come from a clustered or nested structure (e.g., students clustered within schools). Although other methods for clustered data exist, an informal literature search in a recent study found that MLMs are employed in published articles by an overwhelming margin of over 15 to 1 to other clustered data methods. This talk explores how the seeming knee-jerk reaction to apply MLMs to clustered data in education, while well-intentioned, may, at best, overcomplicate many analyses and, at worst, yield estimates that are not congruent with researchers’ expectations. Alternative methods to account for clustering that make fewer assumptions and are simpler to implement are discussed as are broad implications of relying too heavily on MLMs.

Topic: Visual Representations of Data - Review and Recommendations


Presentation Abstract: Creating quality visuals is an essential part of data analysis and publication, especially in education, due to the diversity of the intended audience and the need to effectively communicate accurate information. Research has shown that stakeholders identify with graphics that are familiar, easy to interpret, and relevant to their needs. Therefore, it is important to consider each individual graphic as well as the publication as a whole and make conscientious choices about the data representation. Elements of successful graphics (graphs and tables) include the selection of an appropriate format, color scheme, scale, and style. These elements will be discussed together with examples that demonstrate their impact on readability and interpretability. Once developed, individual graphics can be assembled into larger graphic displays, or dashboards, with similar attention paid to design elements and interpretability. Overall, the characteristics of the audience and the purpose of the content play a crucial role in the development of visuals for publication.

Topic: Post Secondary Enrollment and Assessed Need for Developmental Coursework


Presentation Abstract: This presentation considers the meaning of college readiness from both the district and college perspective. In the past decade, numerous actors in educational research, policy, and practice have converged upon a seemingly practical definition of college readiness that hinges upon a student’s lack of need for postsecondary remedial education. For good or for bad, this conception has become the de facto working definition of college readiness. BERC examined local Baltimore colleges’ assessment of remediation need and high school performance for the Baltimore City graduating Class of 2011. We focus on the four local institutions Baltimore City graduates attend: the Community College of Baltimore County (CCBC), Baltimore City Community College (BCCC), Morgan State University and Coppin State University.

Topic: The Business Case for Sustained Investment in the MLDS Center’s Research Capability


Presentation Abstract: The presenters will use nearly three decades of longitudinal information assembled from multiple administrative data sources to illustrate research challenge and solution lessons learned from a JFI cohort study conducted under a Workforce Data Quality Initiative sub-award from the Department of Labor, Licensing and Regulation.


Continuing proliferation of on-line earnings ‘outcome’ data products that lie beyond the control of SLDS programs nationwide pose at least two threats to these programs—absorption of staff time to understand data quality and interpretation nuances, and investment in explanation of the relevance of these nuances to diverse stakeholders.


A basic theme of the messages is that the L in MLDS Center initiatives matters. The value of the Center’s contributions will grow over time, but only if continuity of the capability occurs.

Stapleton is Associate Professor in the Department of Human Development and Quantitative Methodology and Associate Director of Research with the MLDSC; Alison Preston is also a doctoral student in the Measurement, Statistics and Evaluation program and works on the MLDSC Research Team.


Topic: Strategies for Missing Data in Education Research


Presentation Abstract: In educational research and in large databases alike, missing data can be a pervasive challenge for estimating statistical models appropriately. Simply ignoring or removing observations with missing values can introduce bias, sometimes of large magnitude, into statistical analyses, resulting in inappropriate conclusions which can adversely affect policy decisions. This research talk will highlight the challenges that missing data present, why deleting or ignoring observations with missing values is problematic, and will introduce modern statistical methods (specifically, full information maximum likelihood and multiple imputation) that can be used to address missing data to produce unbiased estimates.
