This study developed a complexometric titration simulation program based on LabVIEW. With built-in approximation and rigorous algorithms, the program can easily simulate and plot a single or a group of complexometric titration curves. On the basis of this program, we developed and implemented an online course to guide undergraduates to (i) compare…

General chemistry laboratory curriculum reform is underway at a midsized state university through a collaborative, inclusive, and iterative approach. Using a backward design approach, faculty collaborated to actualize a shared vision, define laboratory learning objectives, and outline considerations for inclusivity during summer workshops that…

Large, multisection laboratory courses are particularly challenging when managing grading with as many as 35 teaching assistants (TAs). Traditional grading systems using point-based rubrics lead to significant variations in how individual TAs grade, which necessitates the use of curving across laboratory sections. Final grade uncertainty…

Volatile-mediated impacts of microbes on plants have aroused interest among scientists in the life science field. This study describes an inquiry-based laboratory module named "Microbial Talk", which related to microbial volatile-mediated communication, including the process of design, implementation, and assessment. First-year biology…

An undergraduate-level Computational Chemistry project was incorporated initially into a Physical Chemistry course and then into the laboratory curriculum in the subsequent application. Before the introduction of the project, the lectures covered quantum chemistry, spectroscopy, and kinetics while simultaneously including computational chemistry…

These proceedings contain the papers of the 18th International Conference on Cognition and Exploratory Learning in the Digital Age (CELDA 2021), held virtually, due to an exceptional situation caused by the COVID-19 pandemic, from October 13-15, 2021, and organized by the International Association for Development of the Information Society…
