This study is a randomized control trial of full- versus half-day pre-kindergarten in a school district near Denver, Colorado. Four-year-old children were randomly assigned an offer of half-day (four days/week) or full-day (five days/week) pre-k that increased class time by over 600 hours. The offer of full-day pre-k produced substantial, positive…

Currently, there are a vast number of Chinese students taking IELTS each year, but there are scarce studies regarding to how this high-stakes test affects Chinese students. From the perspective of test impact and second language acquisition theories, this study investigates Chinese students' perceptions of IELTS's affective impact in their…

The COVID pandemic forced many higher education institutions to pivot and switch to an online learning environment with minimal preparation. This transition was put in place during the middle of the spring semester, in March. During this transition, instructors had to quickly learn the tools of online teaching, navigate platforms like Webex and…

Best linear prediction (BLP) and penalized best linear prediction (PBLP) are techniques for combining sources of information to produce task scores, section scores, and composite test scores. The report examines issues to consider in operational implementation of BLP and PBLP in testing programs administered by ETS [Educational Testing Service].

In two artificial grammar learning experiments, we tested the learnability of tonal phonotactics forbidding non-domain-final rising tones (*NonFinalR) against the phonotactics banning non-domain-final high-level tones (*NonFinalH). We propose that a firm phonetic ground drives a presumably innate inductive bias favoring *NonFinalR and against…

Previous research has demonstrated the potential of examining log-file data from computer-based assessments to understand student interactions with complex inquiry tasks. Rather than solely providing information about what has been achieved or the accuracy of student responses ("product data"), students' log files offer additional…

As online learning is becoming very popular in formal educational settings and in individual development, online exams are starting to be recognized as one of the more efficient assessment methods. Online exams are effective in either blended or traditional forms of learning, and, when appropriately used, bring benefits to both learners and the…

Progress monitoring of academic achievement is an essential element to prevent learning disorders. A prominent approach is curriculum-based measurement (CBM). Various studies have documented positive effects of CBM on students' achievement. Nevertheless, the use of CBM is associated with additional work for teachers. The use of tablets may be of…

Research experiences are widely understood to be valuable for the intellectual and professional development of undergraduate science students. Course-based undergraduate research experiences (CUREs) have become popular as a means of engaging large numbers of students in research by leveraging institutional supports for laboratory courses. At…

Computer-based test (CBT) and paper-based test (PBT) are two test modes to the test takers that have been widely adopted in the field of language testing or assessment over the last few decades. Due to the rapid development of science and technology, it is a trend for universities and educational institutions striving rather hard to deliver the…

Providing accommodations during assessments for students with disabilities has long been a standard requirement in federal education legislation. Providing assessment accommodations for English learners (ELs), on the other hand, is a newer requirement appearing only over the past few decades. As such, state assessment policies vary widely in terms…

The National Assessment of Educational Progress's (NAEP's) transition to an entirely digitally based assessment (DBA) began in 2017. As part of this transition, new types of NAEP items have begun to be developed that leverage the DBA environment to measure a wider range of knowledge and skills. These new item types include the science…

Enacting equitable teaching practices and sustaining those practices continue to be challenges in most high schools (National Council of Teachers of Mathematics, 2018), particularly in an era of high-stakes testing. Just one year after Boaler and Staples (2008) reported on the successes of "Railside High," where equitable teaching…

This dissertation investigates several topics in state merit-based financial aid research. The main research content includes three separate studies, primarily using the administrative datasets from the Missouri Department of Higher Education. The first study is an empirical paper that examines the effects of the Missouri Bright Flight Scholarship…

For many years, French and Canadian schools have welcomed students from around the world. This article presents the Binogi/ESCAPE project, which supports the integration of a multilingual digital resource in the classroom that presents STEM content through a multilingual lens with associated animated videos and quizzes. The study aims to encourage…
