Pearson product-moment correlation coefficient between item g and test score X, known as item-test or item-total correlation ("Rit"), and item-rest correlation ("Rir") are two of the most used classical estimators for item discrimination power (IDP). Both "Rit" and "Rir" underestimate IDP caused by the…

In data collected from virtual learning environments (VLEs), item response theory (IRT) models can be used to guide the ongoing measurement of student ability. However, such applications of IRT rely on unbiased item parameter estimates associated with test items in the VLE. Without formal piloting of the items, one can expect a large amount of…

This case study investigates, at three Swedish schools, primary school students' knowledge of the equal sign. The schools were chosen as representatives of schools whose students have different socioeconomic backgrounds. The data consist of Grade 3 and 6 students' responses to an assessment form based on Matthews et al. ("JRME,"…

Focus on form (FonF) studies have predominantly addressed its effectiveness in improving learners' syntactic, lexical, orthographic, and phonological knowledge. Extending the scope of this line of research to formulaic FonF practices, this study investigates the relative effectiveness of incidental FonF targeting formulaic versus nonformulaic…

Students with special educational needs (SEN) are systematically hindered in their participation in test-taking and, as a result, are also excluded from participating in high-quality learning. Hence, participation in the assessment situation is connected to power relations and future prospects and possibilities to participate in society. This…

This research used mixed effects to construct a PBL-STEM (problem-based learning with STEM) questionnaire with high validity and reliability. The benefits of PBL-STEM focused on cross-disciplinary and longitudinal research to analyze students' self-efficacy in life science. All 175 university students who attended this course as an elective…

This paper investigates the attitudes of 246 English teachers from Outer and Expanding Circles (EC and OC) towards the global spread of English and the challenges underpinning international proficiency tests. Using a questionnaire, supplemented with interviews with a smaller group of teachers, this study explores how EC and OC teachers perceive…

Background and Context: Despite the increasing implementation of coding in early curricula, there are few valid and reliable assessments of coding abilities for young children. This impedes studying learning outcomes and the development and evaluation of curricula. Objective: Developing and validating a new instrument for assessing young…

Being able to read and write in English as a second language (L2) in the globalized world has been increasingly considered important to gain greater personal, academic, and business achievement. This study investigates English (L2) reading and writing abilities in relation to first language (L1) reading and writing abilities, L2 vocabulary…

This study provides an evaluation of the impact of the International Baccalaureate Diploma Programme introduced in 2006 to 200 public schools in Ecuador. Using a combination of different methodologies in order to have a credible identification strategy, we find that the International Baccalaureate Diploma has a positive impact on academic…

The current discussion about assessment in the language teaching context--involving topics such as immigration and citizenship, and university entrance--has brought with it the issue of justice in assessment. Although in Colombia such concerns are not generally discussed, it is important to consider fairness when it comes to classroom assessment.…

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…

More than half a century of educational efforts have focused on eliminating the Black--White achievement gap. Yet, racial disparities persist. In this article, we describe the issues with educational discourse focused on the achievement gap and the ways structural racism drives the educational experiences and outcomes of Black students. We include…

Extended testing time is a common accommodation given to students with disabilities. However, little is known about whether students who are eligible for the accommodation actually use it, and with what effect. The present study used process data available from the digitally delivered 2017 National Assessment of Educational Progress (NAEP)…

Universal screening has emerged as one strategy within schools for identifying students who demonstrate social emotional and behavioral (SEB) concerns to provide appropriate support. However, research has demonstrated little evidence of equity around diagnostic accuracy; that is, how students might be differentially identified as at-risk for SEB…
