The gold-standard for evaluating the effect of an educational intervention on student outcomes is running a randomized controlled trial (RCT). However, RCTs may often be small due to logistical considerations, and resulting treatment effect estimates may lack precision. Recent methods improve experimental precision by incorporating information…

Four-parameter models have received increasing psychometric attention in recent years, as a reduced upper asymptote for item characteristic curves can be appealing for measurement applications such as adaptive testing and person-fit assessment. However, applications can be challenging due to the large number of parameters in the model. In this…

This report demonstrates the impact of a two-way multilingual family engagement communication platform, TalkingPoints, on student outcomes at a large, urban, K-12 school district. The study used a difference-in-differences model to examine how the introduction of TalkingPoints influenced attendance, behavior, course proficiency, and state…

The purpose of this study was to assess the effectiveness of Uncommon Schools in a turnaround setting. Uncommon was awarded a 2016 grant from the U.S. Department of Education's Investing in Innovation Fund (i3) to support TurnNJ, a project intended to support Uncommon's whole-school turnaround efforts in Camden and Newark, New Jersey. The study…

Resilience, as defined by the literature, deals with the relationship between individuals and their environment. This capstone project followed elementary students over a three-year period to investigate and determine the impact a co-teaching intervention model has on resilience, grade-point average (GPA), state testing scores in English language…

Diagnostic classification models (DCMs) hold great potential for applications in summative and formative assessment by providing discrete multivariate proficiency scores that yield statistically driven classifications of students. Using data from a newly developed diagnostic arithmetic assessment that was administered to 2032 fourth-grade students…

We present a logistic function of a monotonic polynomial with a lower asymptote, allowing additional flexibility beyond the three-parameter logistic model. We develop a maximum marginal likelihood based approach to estimate the item parameters. The new item response model is demonstrated on math assessment data from a state, and a computationally…

This seven-year longitudinal study examined how children's spontaneous focusing on numerosity (SFON), subitizing based enumeration, and counting skills assessed at five or six years predict their school mathematics achievement at 12 years. The participants were 36 Finnish children without diagnosed neurological disorders. The results, based on…

In light of the emergence of statistical analysis techniques based on data mining in education sciences, and the potential they offer to detect non-trivial information in large databases, this paper presents a procedure used to detect factors linked to academic achievement in large-scale assessments. The study is based on a non-experimental,…

This study sought to determine if there is a relationship between students' scores on the eighth-grade Indiana State Test of Education Progress Plus (ISTEP+) exam and success on Indiana's Algebra End-of-Course Assessment (ECA). Additionally, it sought to determine if algebra success could be significantly predicted by the achievement in one or…

Assessment results of 52 special education students in a charter school in Washington, D.C., were used to compare instruction received in co-teaching models of inclusion and resource classrooms to determine their impact on end-of-year standardized state exams. Statistical analysis showed Grade 3-8 special education students currently receiving…

In this paper, we investigate the correspondence between student affect and behavioural engagement in a web-based tutoring platform throughout the school year and learning outcomes at the end of the year on a high-stakes mathematics exam in a manner that is both longitudinal and fine-grained. Affect and behaviour detectors are used to estimate…

In this study, the researcher examined the strength and direction of relationships between NJ School Report Card Variables (NJ SRC) and 2008-2009 NJ ASK 5 Math and Language Arts Literacy (LAL) student test scores. Variables found to have an influence on standardized test scores in the extant literature were evaluated and reported. Analyses were…

The purpose of this study is to validate a test anxiety scale for Italian students. The scale is part of a questionnaire administered after the students' annual competence test by the National Institute for the Educational Evaluation of Instruction and Training (INVALSI). The aim of the scale is to explore the anxiety levels of Italian students…

This article provides a cultural-historical (CHAT) analysis of the practices used by an effective teacher of Latino/a children previously classified as "underachieving" and "beginning/novice" English Language Learners. Although the teacher would not describe her practices in strict CHAT, or sociocultural theory (SCT) terms, our analysis shows that…
