Background/purpose. Higher-Order Thinking Skills (HOTS) development represents a critical challenge in biology higher education. While Project-Based Learning (PjBL) shows promise, empirical evidence remains fragmented across individual studies. This meta-analysis systematically synthesized evidence on PjBL effectiveness in developing HOTS among…

This paper describes a short ion flow activity that can be completed within one lab or lecture session. The activity is focused on the core concept of flow-down gradients and is geared toward undergraduates. No previous knowledge of equilibrium potentials or membrane potentials is required. Students are guided through a set of questions that build…

Inquiry-based course experiences provide a scalable and equitable way to engage students in research. In this study, we describe how we introduced inquiry-based experiences to ten lower-division and upper-division courses across the biology curriculum at a regionally comprehensive public university serving the diverse population in a major…

Academic institutions are increasingly adopting active learning methods to enhance educational outcomes. Using functional magnetic resonance imaging (fMRI), we investigated neurobiological differences between active learning and traditional lecture-based approaches in university physics education. Undergraduate students enrolled in an introductory…

Electron configuration provides insight into the chemical behaviors of elements and is an important concept for students to master in introductory chemistry. To better strengthen undergraduate students' mastery of electron configurations of atoms and ions, we designed a novel, interactive chemistry game called ChemisTree that uses active-learning…

Evidence suggests that students exposed to authentic undergraduate research activities are more successful than those who are not. Not all students in an undergraduate program get an opportunity for mentored research, which is still the popular way to expose them to authentic research. However, involvement in undergraduate research can be…

We conducted an observational exploratory study of distraction by digital devices in multiple different sections across three large undergraduate physics courses. We collected data from two different settings based on the type of devices used for classroom polling: lecture sections that required mobile devices for polling and those that used…

A key tenet of the nature of science is that "knowledge, although reliable and durable, is never absolute or certain" and is subject to change with the accrual of new bodies of evidence (Lederman "et al." 2002). Similarly, pedagogical choices grounded in scientific teaching would also be expected to be modified, refined, and…

Project-based learning is widely used in organic laboratories. This goal-oriented and inquiry-based learning model complements student-centered training. Such models focus on complicated issues or real-world problems on the frontier of chemistry. Students progress through three project phases: preproject, during the project, and postproject.…

Students often experience science, technology, engineering, and mathematics (STEM) courses as competitive, weed-out spaces. Learning Assistants (LAs) have potential to improve students' experiences in these courses. Previously, we elucidated themes describing the impact of LAs on students' sense of STEM belonging and science-related confidence in…

Undergraduate biology students describe fear of negative evaluation (FNE), defined as a sense of dread associated with being unfavorably evaluated in a social situation, as negatively affecting their experiences in active learning courses. Yet, few studies have examined who is prone to experiencing FNE, the severity and duration of FNE, and…

It has been shown that active learning strategies are effective in teaching complex STEM concepts. In this study, we developed and implemented a laboratory experiment for teaching the concepts of Boolean logic gates, molecular beacon probes, molecular computing, DNA logic gates, microRNA, and molecular diagnosis of hepatocellular carcinoma, which…

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.…

Three different experiments that allow the synthesis of the drug paracetamol are described; such experiments were designed for their implementation in undergraduate organic chemistry courses, considering the medical and economic importance of paracetamol. The experience wants to show the students some "real world" applications of organic…

The Beer-Lambert law is a core spectroscopic relationship widely used across the undergraduate chemistry curriculum and beyond. The derivation of this model is a common topic for upper-level chemistry courses. But, due to its abstract nature, this derivation can often seem like a mathematical exercise detached from the molecular origins of…
