Cheating attracts a significant amount of attention in conversations about assessment, and with good reason: if students cheat, we cannot be sure they have met the learning outcomes of their course. In this conceptual article we question the attention given to cheating as a concept and argue that the broader concept of validity is a more important…

Many universities use diagnostic tests to assess incoming students' preparedness for mathematics courses. Diagnostic test results can help students to identify topics where they need more practice and give lecturers a summary of strengths and weaknesses in their class. We demonstrate a process that can be used to make improvements to a mathematics…

This article discusses the conceptualization, measurement, and validity of a recently emerged construct in the field of second language acquisition (SLA)--implicit language aptitude (alternatively "implicit aptitude"). Implicit aptitude is a set of cognitive abilities that enable learners to make unconscious computations of the…

This study describes the development and validation of the Higher Education Student Engagement Scale (HESES). The psychometric evaluations of the scale included: (i) factor structure, (ii) internal consistency, and (iii) criterion validity. The HESES was developed based on our proposed five-factor model of student engagement, which was evolved…

Recent research on entering college student assessment instruments and placement practices has been critical. Critics suggest that commonly used assessment instruments are inaccurate, misused, and lack predictive validity. This article describes valid criticisms and appropriate uses of assessment instruments. It also lists challenges and provides…

The articles presented in this Special Issue provide evidence for many statistically significant relationships among error scores obtained from the Kaufman Test of Educational Achievement, Third Edition (KTEA)-3 between various groups of students with and without disabilities. The data reinforce the importance of examiners looking beyond the…

Mathematical conjectures and theorems are most often of the form P(x) ? Q(x), meaning ?x,P(x) ? Q(x). The hidden quantifier ?x is crucial in understanding the implication as a statement with a truth value. Here P(x) and Q(x) alone are only predicates, without truth values, since they contain unquantified variables. But standard textbook…

In this article, I provide answers to the questions posed by Will Shadish about the history and development of the Schmidt-Hunter methods of meta-analysis. In the 1970s, I headed a research program on personnel selection at the US Office of Personnel Management (OPM). After our research showed that validity studies have low statistical power, OPM…

The "5Essentials Survey" is one of the few validated instruments to measure school climate. Schools that are strong in at least three of the five essential supports are up to 10 times more likely to experience substantial gains in students' math and reading scores. More than 6,000 schools nationwide have administered the…

The use of test scores as a performance measure in high-stakes educational accountability has become increasingly popular since the enactment of the No Child Left Behind Act of 2001 (NCLB), which imposed sanctions such as the threat of losing federal funds unless a state implemented a school accountability system that measures student progress…

In Gargani and Strong (2014), we describe The Rapid Assessment of Teacher Effectiveness (RATE), a new teacher evaluation instrument. Our account of the validation research associated with RATE inspired a review by Good and Lavigne (2015). Here, we reply to the main points of their review. We elaborate on the validity, reliability, theoretical…

This executive summary highlights findings from the full report (published separately) which analyzes construct and predictive validity of a Social and Emotional Learning (SEL) Competency Survey. Students' SEL skill ratings were correlated with other measures of SEL skills and other outcomes of interest. A separate research brief also was…

While college readiness continues to dominate the educational landscape in the United States, students still leave high school not ready for college. As a consequence, admissions officers need to consider all available indicators (e.g., high school performance, admissions test scores, college preparatory courses) in order to effectively evaluate…

Human memory has been thoroughly studied and modeled in psychology, but mainly in laboratory setting under simplified conditions. For application in practical adaptive educational systems we need simple and robust models which can cope with aspects like varied prior knowledge or multiple-choice questions. We discuss and evaluate several models of…

The following essay details a debate between UC Berkeley and a Regent who made charges of discrimination against Asian American students that are similar to the current legal challenges facing Harvard University. The crux of such charges: on average, that one racial or ethnic group is more "qualified" than other groups, often…
