Chen, Zhenhua – Journal of Chemical Education, 2020
In this paper, we develop a general but very simple mathematical foundation for the predefined coefficient graphical method of Hückel molecular orbital theory (HMO). We first present the general solution for the recurrence relation of the coefficients of Hückel molecular orbitals (MOs). Subsequently, for all the three unbranched hydrocarbons,…

Ivchenko, Vladimir – Physics Teacher, 2020
The point particle is an idealized object where rotational and vibrational motion is ignored. Nevertheless, in many cases such degrees of freedom play a significant role. For example, the rotation and vibration of a molecule is an important "reservoir" of its internal energy. The excitation of these types of motion can occur during the…

Xianlong Zhou; Bingyang Lv; Xingxing He; Dongxu Li; Xiaoyang Zhang; Wei Fan; Ping Wang; Jie Liu; Mingxia Yu – Cogent Education, 2024
The integrated curriculum was recently introduced to the foundation medical education in Chinese medical schools. In this context, Wuhan University has offered two integrated courses, ie., Cell, Molecule and Genes (CMG) and Tissue and Function (TF). The purpose of this paper is to unfold problems in the design and implementation of integrated…

Amelia M. Anderson-Wile; Kelly E. Hall; Tevye C. Celius – Journal of Chemical Education, 2024
A structured series of activities has been designed and implemented to promote analysis and data reporting skills for second-year organic chemistry students. Student report sheets were developed to assist students in reporting necessary data for their compounds. A series of rubrics have been utilized by students to promote metacognition and by…

Paola Go´mez Buitrago; Hendrys Tobar-Mun~oz; Danny Arteaga – Journal of Chemical Education, 2024
In response to the great challenge that the teaching of basic sciences currently entails in the new generations of young people and seeking to awaken the interest of our students in chemistry and its areas of influence, we developed an innovative card game named "Amino-structure" which served as a key tool to implement an active learning…

Cinzia Scorzoni; Guido Goldoni; Alberto Rota; Valentina De Renzi – Journal of Chemical Education, 2022
We propose an innovative approach to teaching friction. Our approach aims to educate students on its microscopic nature by highlighting its origin in intermolecular interactions. We have designed a teaching sequence (TS) based on a set of experimental investigations of the properties of a gecko-inspired tape at different length scales. The TS has…

Oni, Oluwasola S.; Adesope, Olusola O.; Wong, Rachel; Nishida, Krista – School Science and Mathematics, 2023
Concept mapping remains widely used in education. However, little is known about how self-constructed concept maps and peer feedback can improve student learning outcomes in chemistry. We investigated the effects of peer feedback on concept mapping and how it improves students' learning performance in a large second-semester, introductory…

Kapici, Hasan Özgür – International Journal of Research in Education and Science, 2023
Being able to move between different representations levels (macroscopic, submicroscopic, and symbolic) is important to understand a chemical phenomenon meaningfully. The current study investigated how pre-service science teachers moved from symbolic representation to sub-microscopic representation. A total of 205 pre-service science teachers,…

Kassem Hallal; Sami Tlais – Journal of Chemical Education, 2023
Different molecular representations are usually used to depict the three-dimensional (3D) structure of organic compounds. Mastering the skill of interconverting one form into another is essential for students to ensure success in organic chemistry. The traditional and recently developed methods for completing such interconversions that rely on 3D…

Kristy M. Erickson – Journal of Chemical Education, 2023
The impact of an interactive in-class Valence-Shell Electron-Pair Repulsion (VSEPR) activity, designed and implemented by the author in her first-year undergraduate chemistry classes, was assessed through the statistical analysis of pre- and posttreatment quizzes on VSEPR theory and the analysis of questionnaires. The activity consisted of…

Bauer, Jurica – Journal of Chemical Education, 2021
Nanotechnology has made a huge impact on science, technology, and society. At the same time, educational institutions at all levels have recognized its relevance and introduced courses that aim at familiarizing their students with the basic concepts of nanotechnology. While the importance of teaching nanotechnology, the contents of such courses,…

Matsutani, Akihiro – Physics Education, 2021
In the violin, the fundamental air cavity mode (the A0 mode) is associated with the sound radiated by the f-holes. The dependences of the sound velocity of the A0 frequency on gaseous temperature and mass were investigated. It was found that the frequency of the A0 mode changed, depending on the molecular weight and the temperature of the gas…

Teaching chemistry and biology students about biologics design remains challenging despite its increasing importance in pharmaceutical development. Monoclonal antibodies, commonly called mAbs, are the most popular biologics. They have been developed into drugs to treat various diseases in the past decades. Multiple challenges exist for designing…
