Microplastic contamination of the environment is a major concern but detecting such contamination presents a challenge, particularly for particles <0.1 mm in size. Community scientists and students who participated in a plankton monitoring program and routinely examined samples of seawater using brightfield microscopy, often found fragments and…

Providing effective feedback is a skill preservice teachers develop through practice. According to Hattie (2012), feedback is essential in the learning process, is prevalent in effective teaching, and its purpose is to help students determine current level of performance, so adjustments can be made to enhance performance to desired level. This…

Traditional oral examination (TOE) is criticized for the shortage of objectivity, standardization, and reliability. These perceived limitations can be mitigated by the introduction of structured oral examination (SOE). There is little evidence of the implementation of SOE in physiology laboratory courses. The purpose of this study was to…

This study was conducted in order to better understand how, if at all, language centers (LCs) are relevant in current technological and methodological contexts of second language education. Five language centers housed by four different institutions of higher education in the western United States were examined. Two representatives from each of…

This paper discusses the experience of online studio activities for a second year project project-oriented design-based learning (PODBL) unit. The experience of delivering campus-based studio activities through an online platform, to a design a small power system, is shared due to COVID-19 restrictions. The student experience is benchmarked with…

Given student familiarity with electronic cigarettes (e-cigs), this lab uses a student-built smoke collection apparatus to collect e-cig vapors to teach students about gas chromatography-mass spectrometry (GC-MS). Students in a second semester, introductory organic chemistry course spent 1 week collecting e-cig vapors and 1 week qualitatively…

In this article, I argue that technical reporting and documentation processes function to mitigate uncertainty and enable complex systems in the endeavor of big science. The argument draws on two years of field research investigating technical reporting and documentation processes at a federally funded supercomputing center dedicated to scientific…

Although modeling is an integral process in applied mathematics, students rarely encounter modeling opportunities in their calculus courses. We introduce a laboratory experience as a starting point for calculus students to investigate multivariable functions. A layered system of coffee and milk serves as a physical model for temperature gradients…

Hands-on dissection-based learning of anatomy offers an unique and valued experience for medical students. Too often however, the inexperienced student's focus is to avoid damage to unfamiliar structures instead of understanding spatial relationships between structures. This results in unfortunate surrender of a critical learning experience.…

Scientific expertise is manifested through extensive cycles of making and acting on decisions. To learn the processes and practices of science, therefore, students must have practice with scientific decision making. We argue that this can only happen if students are afforded agency: the opportunity to make decisions to pursue a goal. In this…

Analysis of stochastic processes can be used to engender critical thinking. Quantum dots have a reversible, stochastic transition between luminescent and nonluminescent states. The luminescence intermittency is known as blinking and is not evident from ensemble measurements. In order to stimulate critical thinking, students design, perform, and…

To span the great distance from the solar system to the farthest clusters of galaxies in the universe, astronomers break down the distance indicators into steps. The nearest ones are measured geometrically, with what is known as parallax. Among the objects whose distances are thus directly measured are a rare type of star known as a Cepheid…

Contribution: A distinct instructional approach to laboratory activities for power system machines, based on hybrid project-based learning (h-PBL). Students develop their own laboratory procedures and explain their results. This approach creates a positive environment to improve students' problem-solving, and their control design and…

To support science education, more than 350 student labs have been established throughout Germany in the last decades. The goal of these out-of-school facilities is to foster the students' scientific literacy and promote interest in STEM (science, technology, engineering, and mathematics) by providing the students with the opportunity to conduct…

Many instructional physics labs are shifting to teach experimentation skills, rather than to demonstrate or confirm canonical physics phenomena. Our previous work found that many students engage in questionable research practices in attempts to confirm the canonical physics phenomena, even when confirmation is explicitly not the goal of the lab.…
