This article examines the risk of crossover contamination in individual-level randomization, a common concern in experimental research, in the context of a large-enrollment college course. While individual-level randomization is more efficient for assessing program effectiveness, it also increases the potential for control group students to cross…

This article describes a usability evaluation that was conducted among student users of improved learning areas (sites) designed as part of the WebLearn Improved Student Experience (WISE) project conducted at Oxford University (UK). WebLearn is the university's internal brand for the Sakai open source virtual learning environment (VLE). The…

In the 2020-2021 school year, many schools and districts around the country implemented routine COVID-19 testing to proactively detect cases among teachers, students, and staff and stop the spread of the virus. Such testing made it possible for many communities to gain the needed support from teachers and parents to reopen schools and resume…

In this study, we propose that the unique needs and characteristics of linguistic minorities should be considered throughout the test development process. Unlike most measurement invariance investigations in the assessment of linguistic minorities, which typically are conducted after test administration, we propose strategies that focus on the…

While many researchers have studied the relationship of socioeconomic status (SES) to adult learners' English language proficiency levels, little is known about this relationship for young learners (i.e., teenagers). In this study, we investigated the degree to which access to English language learning, as reflected by learners' SES, is associated…

Problem Statement: One of the most frequently neglected aspects of testing is teachers' attitudes. Overall, in-service teachers may have a preconception of what testing means and what its implications are both in high and low stakes testing. However, very few studies have addressed the realities or opinions of pre-service teachers. Methods: Two…

This paper discusses the results of a pilot study that explored how prospective secondary school teachers are shaped by learning experiences during their undergraduate mathematics education. The collaborative study, which was conducted by a mathematician and a mathematics educator, drew from the experiences of prospective teachers in a…

Students often have trouble understanding key biology ideas because they lack an understanding of foundational chemistry ideas. AAAS Project 2061 is collaborating with BSCS in the development a curriculum unit that connects core chemistry and biochemistry ideas in order to help eighth grade students build the conceptual foundation needed for high…

Objective: Additional treatments with persisting benefit are needed for ADHD. Because ADHD often shows excessive theta electroencephalogram (EEG) power, low beta, and excessive theta-beta ratio (TBR), a promising treatment is neurofeedback (NF) downtraining TBR. Although several nonblind randomized clinical trials (RCTs) show a medium-large…

The primary purpose of this study was to develop and validate a System for Observing the Teaching of Games in Physical Education (SOTG-PE). Primary pilot testing of the SOTG-PE was conducted in a large, selective, all-boys secondary school in the north-west of England. Two hundred and eighty three pupils aged 11-16 volunteered as participants for…

The aim was to develop a Challenge Module (CM) as a proposed adjunct to the Gross Motor Function Measure for children with cerebral palsy who have high-level motor function. Items were generated in a physiotherapist (PT) focus group. Item reduction was based on PTs' ratings of item importance and safety via online surveys. The proposed CM items…

This article discusses CALL development from both educational and ergonomic perspectives. It focuses on the learner-task-tool interaction, in particular on the aspects contributing to its overall quality, herein called "usability." Two pilot studies are described that were carried out with intermediate to advanced learners of French in two…

This study monitors group supervision for students' field training in a Bachelor's Degree in Social Work (BSW) program and compares it with the experience of the students receiving the traditional individual supervision. The experimental group supervision model is implemented in two consecutive years. Students' experiences are compared at three…

This technical report describes the process of development and piloting of reading comprehension measures that are appropriate for seventh-grade students as part of an online progress screening and monitoring assessment system, http://easycbm.com. Each measure consists of an original fictional story of approximately 1,600 to 1,900 words with 20…

We conducted a pilot study to see how the GED Mathematics Test could be administered on computer with embedded accessibility tools. We examined test scores and test-taker experience. Nineteen GED test centers across five states and 216 randomly assigned GED Tests candidates participated in the project. GED candidates completed two GED mathematics…
