Different framework components were crucial in different aspects of the content design, technology design, and content–technology integration, and throughout this article, we illustrate the application of each framework. As the main objective was to build a resource to support visual-spatial attributes, a shape recognition framework was developed to facilitate students’ abilities to recognize 3D characteristics from 2D representations inherent in VRLEs. The interconnected frameworks’ components complement and reinforce each other, creating a synergistic effect to support visuospatial thinking and representational competence in a VRLE.

One frequently untapped resource to support this effort is the population of experienced GTAs in the department. Graduate students who have recently been in the TA position are poised to speak to incoming graduate students from direct and relevant experience and can foster a positive climate around teaching with their incoming peers. In this account, we describe a GTA training program that relies on significant contributions from volunteer former TAs in the design and facilitation of workshops and activities throughout. This report describes not only the training itself but also the system of mentoring and revision that has been established for continual improvement and participation among the entire graduate student cohort. After four years of utilizing this system, we have identified potential benefits for all parties involved. Improved pedagogical training for incoming graduate students aims to influence (1) the graduate student teaching experience throughout the academic term and the resultant quality of undergraduate instruction within the department, (2) departmental teaching culture and attitudes about teaching, (3) the broader impact of campus-wide collaboration between departments and centers for learning and teaching, and (4) the experience of the senior graduate student volunteers as cultivators of curricula and change-makers within their department.

The citrus peels exhibit distinct microregions, such as oil glands and the flavedo, each containing unique components. Students were guided to compare traditional ESI (flow injection) and DC-iESI for the analysis of components in oil glands and the flavedo. As the flow injection ESI experiment has a requirement for a minimum amount of sample, students had to extract components from bulk citrus peels for MS analysis, which failed to show any differences in the components in these two typical regions. In the DC-iESI experiment, students used nanoelectrospray emitters to freehand collect liquids directly from oil glands and the flavedo, allowing MS analysis of components in these two different microregions. By comparison of these two methods, students have the opportunity to realize the limitations of traditional ESI analysis and learn about using DC-iESI for in situ MS analysis. We believe that this training course can help students enhance their understanding of in situ analysis and broaden their appreciation of MS in modern applications.</p>","PeriodicalId":43,"journal":{"name":"Journal of Chemical Education","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141192257","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}

As educational tools, videos can leverage the dual-channel visual/auditory centers of the human brain. However, videos do not have the searchable elements of print textbooks and can only be read through closed captioning, limiting accessibility for those with hearing loss. Separately, print texts have the advantage of physical tactility but lack audio, online accessibility, or the lightweight portability of modern electronics. Thus, to develop a better combination of both mediums, we created a book with content identically matching an updated video library. This was done in eight months from the videos by using an online software called Maestra to produce a written transcript, which was edited and converted to a digital “e-book” using the TopHat interface. Although prior publications in this <i>Journal</i> have discussed TopHat e-books, none have explained how to create one. This report provides clear instructions and video references on how to do this, along with structural details about our e-book and how it was integrated into two full-year iterations of college organic chemistry.

A recent opportunity to teach catalysis and catalytic reactors, a topic in which the author has substantial background, combined with a desire to contribute to the success of the SDGs provided the platform to address some of the historical gender bias in teaching resources, albeit in only a small way. At the start of the delivery of a 20 h block of teaching over a 6-week period, historical and contemporary women were discussed as part of important contributions to catalysis and catalytic reactors in the chemical industries. The highlighting of women in engineering resonated with some of the students, and this was reflected in the evaluations provided at the end of the content. This prompted a more targeted evaluation of the intervention of showcasing women in engineering, which reported a positive impact on participating students. The results of that follow-up evaluation highlighted that gender balance in role models was important to students, and the intervention was received positively.</p>","PeriodicalId":43,"journal":{"name":"Journal of Chemical Education","volume":null,"pages":null},"PeriodicalIF":3.0,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acs.jchemed.4c00117","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141192074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"教育学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
