Montessori is a highly individualized pedagogy that prioritizes following each child's individual interests over standardized test scores. This quasi-experimental study compares groups of Montessori students (treatment groups, N = 535-710) with control groups of non-Montessori students, matched through the simple matching method, which controls…

This dissertation investigates the impact of attending a STEM-designated elementary school on students' math, ELA (English Language Arts), and science achievement and growth scores. As technology continues to advance in education, educators are exploring innovative instructional methods. With a concerning decline in math proficiency nationwide,…

The purpose of this quantitative, ex post facto study was to determine the difference in students' LEAP ELA achievement scores in grades 3-5 based on the teacher's level of dyslexia knowledge. This study used the Phonological Deficit Theory (PDT) and the Criterion Referenced Assessment Theory (CRT) as its foundation. PDT describes the levels of…

I investigated the relationships between mathematics achievement on the Iowa Assessments and the mastery of four epistemic actions: selecting, analyzing, computing, and representing. These epistemic actions play a crucial role in characterizing mathematical reasoning and are essential for solving mathematics problems in the Iowa Assessments across…

We study a decade of achievement gaps for fifth-, eighth-, and 10th-grade students in Norway using administrative population data. Norway is a wealthy and egalitarian country with a homogeneous educational system, yet achievement gaps between students at the 90th and 10th percentiles of parental income and between students whose parents have at…

The purpose of this study is to examine how the COVID-19 pandemic has affected the learning of students in public education through the analysis of standardized assessment performance before and during COVID-19. The study also compares virtual learning and face-to-face students' change in performance on the standardized assessments. To answer the…

The problem addressed in this study was that in response to low standardized test scores, instructional strategies were required to be implemented in English Language Arts (ELA), but teachers in Grades 1 through 5 in the study site experienced challenges using these strategies to meet student learning needs. The explored teachers' experiences and…

How does the act of explaining influence learning? Prior work has studied effects of explaining through a predominantly proximal lens, measuring short-term outcomes or manipulations within lab settings. Here, we ask whether the benefits of explaining extend to academic performance over time. Specifically, does the quality and frequency of student…

The purpose of this study was to find a way to increase low literacy skills for 5th- grade students in a charter school. The research explored the relationship between the attitudes, behaviors, standardized test scores, and perceptions related to student reading; parents' attitudes and perceptions related to their student's reading; and teachers'…

This research examined if or to what extent there was a relationship between maternal home-based involvement, based on the Family Involvement Questionnaire-Elementary from a mother's perspective, and fifth and sixth-grade students' reading and mathematical achievement scores as measured by STAR reading and math in the state of California. The…

Recent work has demonstrated that having students study worked examples and answer self-explanation prompts as part of their problem-solving practice improves learning on researcher-developed measures of mathematical proficiency. However, little work has been done to date to investigate whether these benefits translate to improvements on the types…

This article contributes to the larger narrative around what makes a mathematics professional development (PD) successful and in what ways. We share a research-based PD model that was implemented in elementary schools in an urban school district for 3 years. The model uses a pseudo lesson study approach and emphasizes standards-based instruction.…

A randomized controlled trial group design study funded by IES NCR Grant R305A090527 was conducted in which 16,307 3rd, 4th, and 5th grade students in 52 school grade-level clusters were randomly assigned to receive ST Math (program revision Gen3), a supplemental mathematics software instructional intervention, or to a business-as-usual…

We study if the Italian school system suffers from gender bias when judging students. To this aim, we use a differences-in-differences approach that compares the teachers' assessments and the standardized test scores that the students receive during the school year. We have census data for all Italian fifth and sixth graders in two different…
