Acid--base chemistry is an important and challenging topic for virtually all chemistry students. Recent works have focused on conceptually linking molecular and symbolic representations to experimental evidence for many chemical concepts. In this work we describe a laboratory exercise designed to address students' conceptual challenges regarding…

Training in chemistry is essential for undergraduate medical students; however, at the National University of Colombia, basic chemistry courses are associated with high fail rates and low academic performance with regard to first semester students, especially in vulnerable special admission populations. A longitudinal study was carried out via…
