Eduardo Martín; Yefrin Ariza – Science & Education, 2025
Contemporary sciences, including the didactics of science, employ computational simulations as tools in their academic endeavors. The construction and application of these simulations are of interest to didactics as they contribute to shaping new perspectives on scientific activity. Consequently, they warrant special attention in…

Qiang Fu; Shiyuan Fu; Hui Yang; Jing Yu; Li Liu – Journal of Chemical Education, 2024
The double-indicator method is often used in the analysis of Na[subscript 2]CO[subscript 3], NaHCO[subscript 3], and NaOH mixtures (carbonate mixtures). In this method, the determination of the volumes at the first and second equivalence points plays a crucial role in analyzing the composition and content of the carbonate mixtures. Here, LabVIEW…

Natalia Spitha; Yujian Zhang; Samuel Pazicni; Sarah A. Fullington; Carla Morais; Amanda Rae Buchberger; Pamela S. Doolittle – Chemistry Education Research and Practice, 2024
The Beer-Lambert law is a fundamental relationship in chemistry that helps connect macroscopic experimental observations (i.e., the amount of light exiting a solution sample) to a symbolic model composed of system-level parameters (e.g., concentration values). Despite the wide use of the Beer-Lambert law in the undergraduate chemistry curriculum…
