An early-alert system (MavCLASS) was developed and piloted in a large gateway math class with 611 freshman students to identify academically at-risk students and provide alert messages. It was found that there was significant association between the alert messages students received and their visits to the university's tutor center. Further, the…

Policy innovation labs are emerging knowledge actors and technical experts in the governing of education. The article offers a historical and conceptual account of the organisational form of the policy innovation lab. Policy innovation labs are characterised by specific methods and techniques of design, data science, and digitisation in public…

The laboratory course is one of the most critical classes in any engineering program. Engineering by its very nature is a practical discipline, and the laboratory course is usually the first and only class where students are given the opportunity to apply the knowledge they are gaining in lecture courses to real-world equipment. As chemical…

We present a hands-on, inquiry-based activity exploring how CO[subscript 2] input to seawater affects the skeletons of several species of reef-building corals and other marine organisms by testing for changes in pH and calcium ion concentrations. Originally developed to inspire and recruit high school students in the state of Hawai'i into the…

The Good Laboratory Practice (GLP) regulations were put into place in 1978. They establish a standard of practice to ensure that results from the nonclinical laboratory study reported to the U.S. Food and Drug Administration (FDA) are valid and that the study report accurately reflects the conduct of the study. While the GLP regulations promulgate…

Laboratory experiments develop students' skills in dealing with laboratory instruments and physical processes with the objective of reinforcing the understanding of the investigated subject. In nuclear engineering, where research reactors play a vital role in the practical education of students, the high cost and long construction time of research…

A laboratory experiment is described that introduces students to "real-world" hazardous waste management issues chemists face. The students are required to define an analytical problem, choose a laboratory analysis method, investigate cost factors, consider quality-control issues, interpret the meaning of results, and provide management…

Surface plasmon resonance (SPR) spectroscopy is a powerful, label-free technique to monitor noncovalent molecular interactions in real time and in a noninvasive fashion. As a label-free assay, SPR does not require tags, dyes, or specialized reagents (e.g., enzymes-substrate complexes) to elicit a visible or a fluorescence signal. During the last…

This linguistic anthropological case study demonstrates the ways in which a heterogeneous lab group of adolescents in a ninth-grade physics classroom constructed "raciolinguistic ideologies" that intersected with their locally constructed notions of science expertise. Using ethnography and discourse analysis this study unpacks how…

STEM Education is sweeping the United States, prompted primarily by the recent adoption of the Next Generation Science Standards. The surge in interest in STEM Education is beneficial for local schools and communities, and promises to positively impact students, teachers, school leaders, community members, and the future workforce. Unfortunately,…

The basis for understanding neurophysiology is understanding ion movement across cell membranes. Students in introductory courses recognize ion concentration gradients as a driving force for ion movement but struggle to simultaneously account for electrical charge gradients. We developed a 17-multiple-choice item assessment of students'…

The lack of exposure to practical work in primary schools leads to incompetency in manipulative skills and students may carry this problem with them to secondary school. To address this issues, an in-depth qualitative study was conducted during transition from primary to secondary school. The research involved 10 primary school students (grade 6)…

In this paper, we describe a lab activity for measuring a spherical balloon's circumference. The procedure we discuss is based on the method used by Eratosthenes to measure the Earth's circumference.

The author taught for years in rural high schools, where students often helped their parents out around the house or farm with chores, learning basic mechanical skills that he could then build on in class. Then the author taught in an urban high school, where student skills often centered on video games and other electronics. The author knew that…

The construction of a voltaic pile (battery) is a simple laboratory activity that commemorates the invention of this important device and is of great help in teaching physics. The voltaic pile is often seen as a scientific toy, with the "pile" being constructed from fruit. These toys use some strips of copper and zinc inserted in a piece…
