We developed a gas-phase Fourier Transform InfraRed Scientific Instrument Simulator (FTIR-SIS, https://ftir.rastonlab.org/) in response to the unavailability of one during the COVID-19 pandemic lockdown of 2020. It features an interactive interface that encourages students to explore different components of a typical FTIR, and it allows them to…

The coronavirus (COVID-19) pandemic prevented students from attending on-site classes. Consequently, their face-to-face interactions decreased. Thus, it became crucial to design learning activities to enhance the motivation of students and inspire them to achieve the desired learning outcomes during the long disruption of on-site classes. Mobile…

Institutions of higher education are seeking to support more active learning among faculty, and that support includes the creation of active learning spaces to support more student-centered course activities. However, incremental development of these learning spaces leads to a sorting of students between active and passive learning environments.…

One of the United States' higher education system's most important tasks is properly preparing elementary teachers to teach science. Teachers' ability to use their science subject matter knowledge (SMK) to effectively develop pedagogical approaches can significantly contribute to their students' engagement in science and motivation to pursue…

Purpose: This study investigates how the practice of dividing students and coursework into leveled categories persists in science education despite decades of efforts aimed at reducing inequities. This study makes underlying logics visible through an empirical analysis of how science educators attempt to reconcile an egalitarian vision of science…

The limitations of traditional education models and the advancement of technology have revealed the need to transform the learning experience. The "Flipped Learning" approach, born out of this need, is a model where students study learning materials in advance and participate in more interactive and hands-on activities in the classroom.…

Due to the COVID-19 pandemic, Biology Teaching Assistants (TAs) were tasked with transitioning and adapting their instruction to an online environment by quickly implementing Emergency Remote Teaching (ERT) practices. Effective online and in-person teaching requires student-centered approaches to support undergraduate student learning. Using…

This study summarizes the comparison of interactive lecturing and technology-supported student-centered pedagogy across six semesters of an introductory physical geology course. A multiple linear regression analysis of 967 student scores shows that absent raw exam scores, homework, and in-class attendance, performance on the first exam (score…

This study introduces a modernized approach to classical volumetric titrations for the undergraduate chemistry curriculum. Leveraging smartphones and digital top-loading balances, we performed mass-based titrations and determined end points using digital color measurements. Our aim was to make classical wet chemistry more accessible and engaging…

The ability to draw molecules based on a given IUPAC name is a fundamental skill in organic chemistry. University students need to acquire appropriate and automated cognitive schemata to master drawing molecules before they can be considered to meaningfully be introduced to face up to reaction equations, cascades, or mechanisms. Similar to experts…

In the current paper, we develop an approach to early science pedagogy that is based on insights about how complex adaptive systems function. Complexity approaches have an important advantage over traditional information-processing approaches: They anticipate the proverbial 'mind with a mind of its own' without having to postulate exclusively…

Measurement instruments of physics, especially those dedicated as teaching aids in physics classroom are improving. These measuring instruments are not only used for measurement purposes, but also to apply theoretical concept into the real world, thus making it easier for students to comprehend. Therefore, this study aims to design, construct, and…

The Phantom Bouquet is a venerable lecture demonstration that does a fine job of showing how a concave spherical mirror can form a real, inverted image. In the original demonstration, a brightly illuminated artificial rose is hung by its stem in front of a concave spherical mirror. The distance from the reflecting surface to the rose is somewhat…

Thomas Young (1773-1829) is best known in the physics community for his double-slit experiment demonstrating the wave property of light and for his work on the tensile properties of solids (Young's modulus). His reputation as a physicist was built almost entirely upon a short, three-year period (1801-1803) of intense work as an instructor in…

The hydrogen spectrum is one of the most commonly demonstrated and most commonly studied. After the visible spectral lines (Balmer series) are explained by the Rydberg's formula, it becomes immediately apparent that there will also be similar infrared and ultraviolet series. As you may have taught your students, these are called the Paschen and…
