Enabling general chemistry students to take part in experimental design activities

Abstract

In this study, we analyzed how general chemistry students generated experimental designs corresponding to general chemistry questions such as the ones typically found in general chemistry textbooks. We found that students were very successful in including experimental design aspects that were explicitly mentioned in the general chemistry questions, but less successful in including other experimental design aspects. We also analyzed the outcomes of students engaging in the counterpart process – expressing general chemistry laboratory experiments as typical general chemistry questions. We found that that students were very successful in considering the various components associated with expressing the experiments when considering each of the various components one at a time, but less successful when considering the various components at the same time. Considerations and suggestions for implementing these types of activities to enable a wide variety of general chemistry students to take part in experimental design are discussed. Implications for research and teaching, including a consideration of ChatGPT, are also presented.

Why Do Fishes Die? Lab Assignment Created Using ChatGPT

“…ChatGPT exhibits excellent linguistic capabilities in many languages and offers a wide range of functions, from text generation for papers, lab reports, and essays to providing factual answers and summarizing information as part of the learning process . It can answer follow-up questions, admit mistakes, challenge incorrect premises, and reject inappropriate demands. , Additionally, ChatGPT can propose solutions to problems, generate laboratory experiments, write conclusions for laboratory protocols, , design and solve written exams, perform chemical calculations, , provide personalized student support, automate administrative tasks, support language learning, and enhance online education . Chatbots can be specifically applied to teaching in large university lecture halls, where they can assist in solving general chemical problems viewed through the lens of current topics …”

Using ChatGPT for Method Development and Green Chemistry Education in Upper-Level Laboratory Courses

“…In chemistry, AI tools have been used to write text for students to evaluate in critical thinking exercises , and on exams . LLMs have also been evaluated as chemistry tutors. , Suggestions abound for other uses by students and instructors. − However, many educators have found errors in AI-generated content in the field of chemistry, − suggesting adopters should use these tools with caution. Recently, faculty in our department used ChatGPT version 3.5 to generate laboratory reports at all levels of the chemistry curriculum, and we evaluated the strengths and weaknesses of these reports .…”
