Abstract:The interdisciplinary field of computational chemistry links many facets of chemistry and provides unique insights into structure, mechanisms, dynamics, and the interplay between them. Various approaches were proposed for integrating computational chemistry in the undergraduate classroom, all highlight the benefits of including it in the chemistry curriculum. This study focuses on the desirable learning outcomes, and defines a structural framework of computational chemistry literacy. Based on this approach ana… Show more
“…For undergraduate chemistry students, the interdisciplinary area of computational chemistry provides an opportunity for authentic learning. 1 Learning outcomes across a curriculum improve when topics are interconnected rather than taught in isolation. In addition, learning outcomes are enhanced when students can link theoretical knowledge with practical applications 2−4 and an inherent application of computational chemistry is the ability to predict and rationalize experimental results.…”

“…Training opportunities in computational chemistry may be hindered, at least in part, by either a real or perceived disconnect to undergraduate coursework. , For example, teaching computational chemistry may require additional computational infrastructure for laboratories and hands-on activities, a different physical or online learning environment, or the need for pre-existing student skills in programming and command line-driven software operation. , Attempts to tackle these problems have been made by other educators in this field by making use of centralized interfaces, such as WebMO, which aim to simplify the process of performing quantum chemistry calculations to make it more accessible to a wider audience.…”
The conformational isomerism of disubstituted ethanes
is a well-known
concept that is part of every chemistry curriculum. Due to the species’
simplicity, studying the (free) energy difference between the gauche and anti isomers has been the testing
ground of experimental and computational techniques, such as Raman
and IR spectroscopy, quantum chemistry, and atomistic simulations.
While students normally receive formal training in spectroscopic techniques
during their early undergraduate years, computational methods often
receive less attention. In this work, we revisit the conformational
isomerism of 1,2-dichloroethane and 1,2-dibromoethane and design a
hybrid computational and experimental laboratory for our undergraduate
chemistry curriculum with a focus on introducing computational techniques
as a complementary research tool to experimentation. We show how commonly
available Raman spectrometers and atomistic simulations performed
on desktop computers can be combined to study the conformational isomerism
of disubstituted ethanes while discussing the advantages and limitations
of the different approaches.

“…However, TPACK is insufficient when new technology is adopted. In a recent review dealing with the integration of computational chemistry in chemistry courses, Tuvi-Arad [ 28 ] presented several challenges that inhibit the integration of advanced technology. First, she mentioned the TK of the lecturers and that they should be familiar with the relevant software.…”
The experience of graduate degree lecturers in the natural sciences when they switched to online teaching during the Covid-19 pandemic is described. The shift to online teaching throughout the pandemic provided an opportunity to evaluate how lecturers integrate technology into their teaching and what they need to improve their remote teaching. This study used a twofold perspective of TPACK (Technological Pedagogical Content Knowledge) and self-efficacy in online education. Its data were derived from pre-and post-questionnaires, comprising closed and open-ended questions, given at the start and end of the semester. We found that lecturers focused on learning and applying technological and techno-pedagogical knowledge but paid less attention to the integration of three components: technology, pedagogy, and scientific content. Although no statistically significant differences in lecturers’ perceived self-efficacy was found between the start and the end of the semester, at the end of the semester we found a statistically significant correlation between the variables involved in building self-efficacy in online teaching: (1) satisfaction with online teaching and the belief that (2) technology promotes teaching, student interactions, participation, and engagement. Our results enabled us to identify the knowledge aspects that lecturers implemented initiatively and to better understand what aspects required more professional development training. In addition, the results emphasized the importance of developing the lecturers’ self-efficacy for online teaching. These insights can help to improve and enhance online teaching in higher education.
“…In the present work a new optional course in molecular modeling of materials is offered to students coming from materials engineering, chemical engineering and biomedicine engineeries is shown as an ongoing project. Tuvi-Arad [12] presents three different models for including computational chemistry in the undergraduate program: the specialized course model, the augmented course model, and the islands of computations model. Here, an specialized course is the way chosen to incorporate the theoretical and practical concepts.…”
Molecular modeling is a chemistry tool that has been widely used in the last decades to mainly support the basic concepts of general chemistry and organic chemistry, in both undergraduate programs of basic sciences and some technological careers. Despite its use, except in some very specific cases, it has been extensively employed as illustrative examples of the chemical concepts that were being demonstrated. Despite the numerous existing applications to comprehend the phenomena behind the development of new materials and biomedicine, it is difficult to find a conceptual introduction of molecular modeling applied to specific problems on the modern engineeries within the undergraduate programs. In the present work, it will be shown the introduction and adaptation of molecular modeling concepts within a new optional course for students coming from materials engineering, chemical engineering and biomedicine engineeries. Different approaches to problem-based and small project-based learning are presented to encourage the scientific spirit of students using techniques of molecular modeling that had not been visited throughout their studies and, thus, to discover their potential appliacation in a more specialized context.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
