To tackle these challenges, we developed a preconfigured image on Jetstream2, a U.S. academic cloud platform supported by the National Science Foundation. This image, shared with the community, allows chemistry instructors to effortlessly deploy a JupyterHub platform for their classrooms, facilitating the teaching of programming skills. Integrated with the automatic grading package nbgrader, the JupyterHub Web site created from this image enables seamless assignment creation, distribution, and automatic grading on a cloud-based platform. Students can access assignments directly through their web browsers without the need to install software or configure their local machines. This tool empowers educators to equip future scientists with essential coding skills, enabling them to tackle interdisciplinary challenges and drive chemical discoveries. To ensure the accessibility of this approach worldwide, we created a preconfigured image on the Google Cloud Platform and provided detailed instructions for setting up this nbgrader-integrated JupyterHub instance from scratch.","PeriodicalId":43,"journal":{"name":"Journal of Chemical Education","volume":"102 9","pages":"4130–4138"},"PeriodicalIF":2.9,"publicationDate":"2025-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, computational chemistry has become an important tool in chemistry teaching. To illustrate the important application of computational chemistry in organic chemistry, comparison of the stability of 1-naphthalenesulfonic acid and 2-naphthalenesulfonic acid and investigation of the reason for their different stability are put forth as an example. In addition, the stability of other isomers formed by −F, −CN, −O–, −OMe, and −NH2 groups was also compared. The conclusions are that intramolecular noncovalent interactions including attraction and repulsion occur in both 1-naphthalenesulfonic acid and 2-naphthalenesulfonic acid. Although intramolecular noncovalent interactions of 1-substituted isomers are stronger than those of their corresponding 2-substituted isomers, not all 1-substituted isomers are less stable than their corresponding 2-substituted isomers. This new viewpoint may provide a theoretical basis for organic chemistry teaching. Application computational chemistry to the teaching of organic chemistry has stimulated most students’ interest in learning organic chemistry. The questioning spirit of the students is worth encouraging.","PeriodicalId":43,"journal":{"name":"Journal of Chemical Education","volume":"102 9","pages":"4152–4159"},"PeriodicalIF":2.9,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The respondents were composed of the faculty members teaching major chemistry subjects and the graduates of the program from 2019 to 2024. A teaching style questionnaire was employed, and the data were analyzed statistically for the significant relationship between the variables. It was revealed that the faculty members employed a mix of the different teaching styles in all subfields of chemistry. The program was composed of above average students in terms of academic grades with no significant difference between the subfields of chemistry. Moreover, it was revealed that the employed teaching styles of the faculty members have varying relationship to academic grades. The results suggest that utilizing a mix of teaching styles in chemistry inhibits its direct effect on the academic grades of students. As such, bias in instruction delivery may be eliminated by employing a mix of teaching styles. Researchers can build on these initial findings, test them in different settings, and uncover additional variables or patterns that might be crucial in understanding what truly impacts students’ academic performance in chemistry programs.","PeriodicalId":43,"journal":{"name":"Journal of Chemical Education","volume":"102 9","pages":"3871–3877"},"PeriodicalIF":2.9,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to stimulate students’ interest in learning and enhance their understanding and cognition of bonding, we created the Bonding Pattern Activity in the teaching of “General Chemistry”, a new first-year undergraduate activity where students use a web browser to query compounds from a free chemical database owned by the Royal Society of Chemistry and plot the distribution map of bonding elements in the periodic table for each element. Through this activity students can vividly understand how bonding elements are distributed in the periodic table from a systematic perspective and can have a better understanding of element similarity and periodic properties. To make this activity possible, we developed an operation manual to extract data from the Internet and an open-source python program to draw the distribution map. Students were excited by the analysis of the large data set from the Internet in comparison to traditional limited data in textbooks and appreciated their acquired knowledge about bonding patterns. Furthermore, the process by which students find missing data in the database could be used to engage them with the chemical literature. The Bonding Pattern Activity is entirely open-source and readily deployable at any university wishing to teach “General Chemistry” or “Inorganic Chemistry”.","PeriodicalId":43,"journal":{"name":"Journal of Chemical Education","volume":"102 9","pages":"4175–4179"},"PeriodicalIF":2.9,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While materials at the nanoscale exhibit unique properties compared to their bulk counterparts, there is a need to introduce a dedicated course in the Chemical Engineering program to equip students with specialized knowledge. This study aims to develop an elective course titled ‘Nanotechnology’ as part of the Chemical Engineering bachelor’s curriculum. To enhance engagement, three innovative assignments were introduced as part of the assessment component, namely (i) Finding ‘Nano’ in the Market, (ii) Nano-Hazard Symbol Design Competition, and (iii) Term Paper Writing. The first two assignments were designed to align with the learning styles of the 100 students enrolled in this course, who belong to the late Millennial generation (born in 1996) or the early Generation Z cohort (born between 1997 and 1998). These activities enable students to explore the market for commercial nanoproducts and apply their creativity in designing a unique hazard symbol to represent nanotoxicity. Assessment results showed an excellent attainment of program learning outcomes contributing to the development of essential engineering skills, including engineering knowledge (82.28%), problem analysis (79.46%), investigation (81.44%), and environmental sustainability (82.66%). 86 out of 96 students who took the course strongly agreed that the learning activities contributed to their studies and helped expand their knowledge in this specific area. It is envisaged that incorporating this elective course could equip future chemical engineers with essential nanotechnology knowledge to adapt to its rapid growth in the current and future chemical industries.","PeriodicalId":43,"journal":{"name":"Journal of Chemical Education","volume":"102 9","pages":"3982–3992"},"PeriodicalIF":2.9,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This centers the purpose of spectroscopy and spectrometry on understanding chemical phenomena, often chemical reactions, rather than on solving inauthentic unknown puzzles which are not connected to a chemical phenomenon.
