Abstract
Integrating active research into educational laboratory experiences is critical for exposing students to the impact research can have. By using discoveries and experiments from ongoing active research, these laboratories create a crucial early career opportunity for students to directly engage in current scientific research. A summer laboratory program for incoming undergraduate chemistry majors was designed and implemented. Students with no required prior laboratory experience took part in experiments and discussions relating to Au–Sn alloy nanoparticles, focusing on concepts from nanoscience, solid state chemistry, and photonics. Societal impacts on sustainability and critical materials were also discussed. A strong emphasis is placed on teaching solid state chemistry and nanoscience, which can be challenging to incorporate into existing introductory laboratory experiences due to time, safety, and approachability limitations. This experiment is aqueous, can be performed in a single session, and requires no sophisticated equipment. The laboratory was reproduced solely using reagents and equipment available in our general chemistry stockroom. Instructor materials are also included that adapt this laboratory for teaching crystal structures and X-ray diffraction at an advanced level.
将积极研究融入教育实验室体验对于让学生了解研究的影响至关重要。通过使用正在进行的积极研究中的发现和实验,这些实验室为学生直接参与当前的科学研究创造了重要的早期职业机会。我们为化学专业的新生设计并实施了一项暑期实验室计划。没有实验室经验要求的学生参加了与金锑合金纳米粒子有关的实验和讨论,重点是纳米科学、固态化学和光子学的概念。此外,还讨论了对可持续发展和关键材料的社会影响。本实验着重强调固态化学和纳米科学的教学,由于时间、安全和易接近性等方面的限制,将其纳入现有的入门实验经验具有挑战性。本实验为水性实验,可在一节课内完成,不需要复杂的设备。本实验完全使用我们普通化学库房中的试剂和设备。本实验还附有指导材料,可用于晶体结构和 X 射线衍射的高级教学。
期刊介绍:
The Journal of Chemical Education is the official journal of the Division of Chemical Education of the American Chemical Society, co-published with the American Chemical Society Publications Division. Launched in 1924, the Journal of Chemical Education is the world’s premier chemical education journal. The Journal publishes peer-reviewed articles and related information as a resource to those in the field of chemical education and to those institutions that serve them. JCE typically addresses chemical content, activities, laboratory experiments, instructional methods, and pedagogies. The Journal serves as a means of communication among people across the world who are interested in the teaching and learning of chemistry. This includes instructors of chemistry from middle school through graduate school, professional staff who support these teaching activities, as well as some scientists in commerce, industry, and government.
