How much students benefit from a school intervention depends on how well the intervention is delivered

When a new curriculum is introduced at a school, the quality of its implementation will vary across teachers. Does this matter? In this study, teachers varied widely in how well they implemented a 20-lesson social and emotional blended-learning curriculum. Teachers who delivered the program at higher quality, for example, encouraged student reflection and participation and provided feedback to students on how to improve skills. Teachers who delivered the program at higher quality had students with higher levels of motivation (growth mindset, effort beliefs, and learning goals) at the end of the program compared to teachers who delivered at lower quality.

Modeling and Comparing Seasonal Trends in Interim Achievement Data

James Soland & Yeow Meng Thum

PDF Version

Introduction

Interim achievement tests are often used to monitor student and school performance over time. Unlike end-of-year achievement tests used for accountability, interim tests are administered multiple times per year (e.g., Fall, Winter, and Spring) and vary across schools in terms of when in the school year students take them. As a result, scores reflect seasonal patterns in achievement, including summer learning loss. Despite the prevalence of interim tests, few statistical models are designed to answer questions commonly asked with interim test data (e.g., Do students whose achievement grows the most over several years, tend to experience below-average summer loss?). In this study we compare the properties of three growth models that can be used to examine interim test data.

Performance Evaluations as a Measure of Teacher Effectiveness When Implementation Differs

James Cowan, Dan Goldhaber, Roddy Theobald

PDF Version

Overview

We use statewide data from Massachusetts to investigate the school role in teacher evaluation. Schools classify most teachers as proficient but differ substantially in how frequently they assign other ratings. We show these patterns are driven by differences in the application of standards across schools, not by differences in the distribution of teacher quality.

Gather-Narrow-Extract: A Framework for Studying Local Policy Variation Using Web-Scraping and Natural Language Processing

Kylie L. Anglin

PDF Version

Many education policy decisions are made at the local level. School districts make policies regarding hiring, resource allocation, and day-to-day operations. However, collecting data on local policy decisions has traditionally been expensive and time-consuming, sometimes leading researchers to leave important research questions unanswered.

This paper presents a framework for efficiently identifying and processing local policy documents posted online – documents like staff manuals, union contracts, and school improvement plans – using web-scraping and natural language processing.

Mitigating Illusory Results through Preregistration in Education

Summary by: Claire Chuter

PDF Version

Good researchers thoroughly analyze their data, right? Practices like testing the right covariates, running your analyses in multiple ways to find the best fitting model, screening for outliers, and testing for mediation or moderation effects are indeed important practices… but with a massive caveat. The aggregation of many of these rigorous research practices (as well as some more dubious ones) can lead to what the authors call “illusory results” – results that seem real but are unlikely to be reproduced. In other words, implementation of these common practices (see Figure 1 in the article), often leads researchers to run multiple analytic tests which may unwittingly inflate their chances of stumbling upon a significant finding by chance.

The Methodological Challenges of Measuring Institutional Value-added in Higher Education

Tatiana Melguizo, Gema Zamarro, Tatiana Velasco, and Fabio J. Sanchez

PDF Version

Assessing the quality of higher education is hard but there is growing pressure for governments to create a ranking system for institutions that can be used for assessment and funding allocations.  Such a system, however, would require a reliable methodology to fairly assess colleges using a wide variety of indicators. Countries with centralized governance structures have motivated researchers to develop “value-added” metrics of colleges’ contributions to student outcomes that can be used for summative assessment (Coates, 2009; Melguizo & Wainer, 2016; Shavelson et al. 2016). Estimating the “value-added” of colleges and programs, however, is methodologically challenging: first, high- and low-achieving students tend to self-select into different colleges– a behavior that if not accounted for, may yield to estimates that capture students’ prior achievement rather than colleges’ effectiveness at raising achievement; second, measures considering gains in student learning outcomes (SLOs) as indicators at the higher education level are scant. In our paper, we study these challenges and compare the methods used for obtaining value-added metrics in the context of higher education in Colombia.

Latent Profiles of Reading and Language and Their Association with Standardized Reading Outcomes in K-10th Grade

Barbara R Foorman, Yaacov Petscher, Christopher Stanley, & Adrea Truckenmiller

PDF Version

Differentiated instruction involves tailoring instruction to individual student’s learning needs. While critical to effective teaching, an understudied first step in differentiated instruction is understanding students’ learning profiles – that is, their strengths and weaknesses in knowledge and skills.  It is only after a student’s learning profile is understood that a teacher can individualize instruction. But how can educators best measure learning profiles to facilitate differentiated instruction?

Descriptive approaches such as informal reading inventories lack the psychometric rigor required for purposes of classification, placement, and monitoring growth.  However, quantitative approaches to classifying and clustering (i.e., grouping) students by skill classes and validating the clusters by relating them to standardized tests is a reliable tool for creating profiles. The objective of this study was twofold. First, to determine the profiles of reading and language skills that characterized 7,752 students in kindergarten through 10th grade. Second, to relate the profiles to standardized reading outcomes.
