Community college students who are juggling busy lives may be drawn to enroll in self-paced online courses. Shorter, eight-week versions of online courses are an option for these students instead of taking full sixteen-week versions. However, because eight-week courses cover the same amount of material in half the time, student success may be…

Immersive research opportunities allow students to take ownership of their learning, explore based on curiosity, and engage in the scientific process while developing confidence and skills. However, research positions for biology undergraduates are limited, and conventional teaching labs are often restricted to pre-designed experiments without…

This study investigated the role of experiential learning and peer mentors in undergraduate biology at a community college. While the impact on all students was studied, special attention was paid to the effect interventions had on underrepresented minority students. Thirty-three sections of an introductory biology class were randomly assigned to…

The educational game Interactions 500 was extensively used remotely during the COVID-19 Pandemic as an activity at the Federal University of Ceará (Brazil) to help students review intermolecular forces. In the postpandemic years, the game was also used face-to-face in the classroom. However, Apple Store and Google Play Store removed it from their…

Students beginning college chemistry are expected to arrive prepared with fundamental, prerequisite conceptual understanding and skills from high school. While some topics may be reviewed explicitly in the course, prerequisite material-including hidden prerequisites often overlooked by faculty-is typically considered assumed prior knowledge and…

This article discusses how Google Earth represents an exciting opportunity to incorporate active learning in Earth science courses. Web-based Google Earth is easier to use than its initial incarnation that required users to download a large file in order to access the tool. Google Earth for Chrome can be used to engage students in activities that…

The need to integrate computation into the physics curriculum has long been established: using simulations and computational modeling can enhance students' conceptual understanding, and the computational skills students acquire are both useful and necessary in their careers. However, making changes to an established physics course is a challenge…

Standard glass pH electrodes are ubiquitous instruments used in research and in classrooms to measure the hydrogen ions present in a solution. While many chemists and educators have communicated ways to support teaching conceptual understanding of solution pH and the function of pH probes and dyes, the community lacks a methodology that enables…

Epistemological views characterise how individuals view the certainty, source and organization of knowledge. Previous research has demonstrated some relationships between epistemological views and nature of science (NOS) views. These relationships may be particularly interesting for biology students who are learning about topics such as evolution…

The conservation law of energy and momentum can be examined and demonstrated by a well-known collision experiment. In this experiment, several identical elastic balls are suspended from a horizontal frame. When the ball at one end is pulled aside and released, thus allowing it to swing like a pendulum, it hits the next ball. The outcome is…

There is a pressing need to improve the sustainability of educational improvement efforts, but sustainability remains undertheorized in science education. In this article, we draw upon frameworks from organizational culture and sustainability to characterize change within a single undergraduate science department. This in-depth longitudinal case…

Given the ever-increasing diversity of both the global and national community, diversity and inclusion are critical topics for consideration in healthy organizational settings. Promotion of diversity and inclusion is especially important for institutions of higher learning since diverse and inclusive environments more accurately teach learners…

A central theme in introductory and advanced chemical education courses pertains directly to the transfer of electrons between atoms, ions, or molecules. This article presents theoretical treatments of electron transfer with specific attention toward applying these principles to experiment. The goal is to revitalize teaching electron transfer at…

An upper-division undergraduate- or graduate-level laboratory experiment, challenging students to identify bovine serum albumin, equine myoglobin, bovine calmodulin, and bovine cytochrome c, uses four methods of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS): linear positive, in-source decay, peptide…

X-ray fluorescence is subject to significant matrix effects, which must be corrected in order to obtain accurate quantitative results. These are due to both absorption and enhancement effects, which are a consequence of the fact that both the analyte and the matrix absorb and fluoresce in the X-ray region, and this affects the magnitude of the…
