Teacher shortages are affecting every state around the country right now. What is the best way to address these chronic teacher shortages?

View Answer >

Chronic teacher shortages are a systemic problem, which means it’s largely a result of the system in which we educate and support teachers. We know, for example, that many alternative teacher preparation programs — where students come in with a bachelor’s degree outside of the field of education and take only a few courses in preparation for teaching — actually contribute to teacher shortages.So part of the answer is investing in traditional teacher preparation programs and in financial aid. Our team at CEHD’s Center for Excellence and Equity in Teacher Preparation is working directly with Delaware students from motivation to pursue teaching, through recruitment into UD teacher preparation programs, through graduation from those degree programs and into schools within Delaware, whenever possible. For example, our Teachers of Tomorrow program introduces underrepresented high schoolers to the field of education through an immersive, two-week summer institute at UD where they can learn about our programs, meet current students and talk with educators. In partnership with high-needs Delaware school districts and the Delaware Department of Education, our Teacher Residency program allows early childhood education, elementary teacher education and secondary STEM education students to pursue yearlong, paid teaching placements in Delaware schools. Overall, we find that 80% of the students we recruit from Delaware stay in our schools to teach.

What are your three biggest concerns about K-12 education going into this academic year?

View Answer >

The overarching concern for many K-12 teachers and administrators is creating a sense of continuity as children and young adults go back to school. The three big concerns that contribute to this issue are teacher turnover, school leader turnover and the number of long-term substitutes who are not fully prepared to teach in classrooms. These trends were already in place before the pandemic, but the pandemic heightened this crisis.

Spillover effects of recruiting teachers for school turnaround: Evidence from Tennessee

Educational Evaluation and Policy Analysis

2023 Many districts and states have implemented incentives to recruit teachers to low-performing schools, and previous research has found evidence that these incentives are effective at attracting teachers. However, effects on the schools and students these teachers leave behind have not been examined. This study focuses on the spillover effects of recruiting effective teachers to Tennessee’s Innovation Zone (iZone) schools. We find the short-term effects of losing these teachers range from −0.04 to −0.12 SDs in student test score gains, with larger negative effects when more effective teachers leave. However, combining both these negative effects in schools teachers leave and the positive effects in iZone schools yields overall net positive effects.

Development and Validation of a Tool to Examine Program-Wide Implementation of the Pyramid Model

Journal of Positive Behavior Interventions

2023 In recent years, there has been increased attention regarding systems-level implementation to support the sustained use of evidence-based interventions and supports in authentic early childhood settings. With this comes a need to accurately measure implementation fidelity of the critical features within a framework as well as individual practices. Program-Wide Support for Pyramid Model Implementation (PWS-PMI) provides an approach for early childhood programs to develop such a framework that can underpin evidence-based practices in their classrooms. This article describes an evaluation of the technical properties of the Supporting Program-wide Implementation Fidelity Instrument (SPIFI), a fidelity tool that was developed to be used by typical evaluators to measure PWS-PMI in these settings.

Multiple Paths to Evaluation Influence and Social Betterment

Evaluation Roots: Theory Influencing Practice

2023 In this chapter, we describe the key components of our theory of evaluation practice. Our theory does not specify a single approach to evaluation. Rather, it presents a contingent approach, tailored to the specific context in which an evaluation is planned and implemented, and to the specific pathways available in that context for improving social conditions, a goal we refer to as social betterment. Our approach is premised on the idea that evaluation exists to improve the accuracy of information about such things as the description of programs, the people they serve, and the outcomes they produce. This is the reason evaluation rests on the application of systematic research methods. A second key premise of our approach is that evaluation exists to help move us toward social betterment.

Online Credit Recovery as an Intervention for High School Students Who Fail Courses

Educational Policy

2023 Online credit recovery (OCR) refers to online courses that high school students take after previously failing the course. Many have suggested that OCR courses are helping students to graduate from high school without corresponding increases in academic skills. This study analyzes administrative data from the state of North Carolina to evaluate the efficacy of OCR using full data from public and private OCR providers. Findings indicate that students who fail courses and enroll in OCR are 20 percentage points more likely to earn course credit, have lower test scores of up to two tenths of a standard deviation, and are about eight percentage points more likely to graduate high school within 4 years than students who repeat courses traditionally.

Accountability-driven school reform: are there unintended effects on younger children in untested grades?

Early Childhood Research Quarterly

2022 Test-based accountability pressures have had mixed effects on the student outcomes that they are intended to improve. Accountability policies have also resulted in transfers of less effective teachers into untested early grades and more effective teachers in early grades into tested grades, which could yield unintended negative consequences. In this study, we use a sharp regression discontinuity design to examine the effects of accountability-driven school reform on student outcomes and teacher mobility in 38 elementary schools assigned to reform in North Carolina. We find evidence of a small increase in chronic absenteeism and grade retention in grades K-2 in the first year of reforms.
