We describe a paper-based microfluidic device for iron(III) assay in an applied instrumental analysis laboratory. Simple and convenient devices were fabricated by the students using patterning of filter paper to investigate three different procedures: drawing a boundary with eyeliner or wax pen; drawing a boundary with waterproof permanent marker…

Maximizing the flow of students through the science, technology, engineering, and math (STEM) pipeline is important to promoting human capital development and reducing economic inequality. A critical juncture in the STEM pipeline is the highly cumulative sequence of secondary school math courses. Students from disadvantaged schools are less likely…

Quantum computing is a growing field at the intersection of physics and computer science. The goal of this article is to highlight a successfully trialled quantum computing course for high school students between the ages of 15 and 18 years old. This course was designed to bridge the gap between popular science articles and advanced undergraduate…

Students who participate in advanced coursework in high school are more likely to enroll and persist in college. This study measured college readiness indicators of high school seniors enrolled in the Utah Spanish Bridge Program and analyzed whether performance differed based on race/ethnicity or on parent college completion. Findings show that…

Background/Context: Taking even one Advanced Placement (AP), International Baccalaureate (IB), dual enrollment, or other college-preparatory course is positively associated with student outcomes including test scores; high school graduation; and college matriculation, major choice, and completion (Adelman, 2006; An & Taylor, 2019; Author,…

The National Council of Teachers of Mathematics (2000) emphasizes the importance of communication in mathematics and mathematics education. Effective mathematical communication is essential in mathematics instruction, as it is a collaborative and social activity between teachers and students (Moschkovich, 2002; Khairunnisa et al., 2020). This…

This paper reports the findings of a study that investigated why a large number of test-takers show a low performance in four language skills (listening, speaking, reading, and writing) offered in an entry test used by a College of Technology in Oman to place students in advanced diploma and bachelor's degree programs. The main research question…

Students in advanced undergraduate chemistry laboratories are required to undertake a wide range of complex and multistep syntheses and analytical procedures, and prospective employers of chemistry graduates seek students with proven skills in these areas. Our approach has been to use video resources which are made available to students both ahead…

Due to the efficiency, sustainability, and advances in firefighting technologies, the allowable height for wood buildings was increased from 4 to 6 storeys in 2015 and will be further increased to 12 storeys in the 2020 edition of the National Building Code of Canada, as a result of the advent and application of mass timber products. To match the…

Massive Open Online Courses (MOOCs) can appeal to very large masses as a distance education model and provide the same quality and standard education with large user groups worldwide via the internet. In MOOC systems, users can get the course they want for free or for a small fee in the application they are registered with, using videos, lecture…

Generalization is a critical component of mathematical reasoning, with researchers recommending that it be central to education at all grade levels. However, research on students' generalizing reveals pervasive difficulties in creating and expressing general statements, which underscores the need to better understand the processes that can support…

Physics and mathematics are interrelated as part of the science, technology, engineering, and mathematics (STEM) disciplines. The learning of science is supported by mathematical skills and knowledge. The aim of this paper is to determine the cognitive obstacles of in-service undergraduate physics student-teachers' understanding of the concept of…

Although recent years have witnessed increasing interest in learning Chinese as a foreign language (CFL) in China and around the world, there seems to be a paucity of research into the medium of instruction in the CFL classroom. This paper describes a study of the practice of MoI choice in the CFL classroom, situated within the framework of…

This paper focuses on the mathematical sensemaking by women of color in the USA as part of the global effort of dismantling deficit narratives about historically marginalized groups of students. Following Adiredja's anti-deficit framework for sensemaking, this cognitive study invited a group of women of color to share their understanding of basis…

This report provides outcomes for Austin Independent School District (AISD) graduates from the Class of 2018 who were ever classified as English learners (ELs) in terms of advanced coursework, college readiness assessments, and postsecondary enrollment.
