Xinyun Zhao; Tsunghsueh Wu; Xi Chen; Lamei Wu; Zhongqiang Zhou – Journal of Chemical Education, 2023
An inquiry-based learning approach was implemented into comprehensive organic chemistry experiments focusing on the formation process of N-phenylbenzamide from the reaction between N-benzylideneaniline and benzoyl peroxide in commercial dimethyl sulfoxide. Students conducted comparative experiments using alternative reagents or reaction conditions…

Mei Zhang; Wangmin Hu; Wenjing Liu; Chang Lei; Jun Guo; Hongcai Shang; Junling Hou – Journal of Chemical Education, 2022
Interdisciplinary experiments within chemistry are very important for the improvements in the overall quality of the education received by students. In this work, we describe an interdisciplinary experiment that was successfully completed by undergraduate students. This training integrates multiple disciplines including natural product medicinal…

Goeltz, John C.; Cuevas, Lia A. – Journal of Chemical Education, 2021
Acid-base titration laboratories are perennially offered to general chemistry students in preparation for summative assessments of their hands-on and quantitative skills in the field. Here, we present a guided inquiry-based activity focused on total titratable acidity (TTA) as alternative to standard "cookbook" titration laboratory work.…

Harwood, Cynthia J.; Hewett, Sarah; Towns, Marcy H. – Journal of Chemical Education, 2020
This communicaton shares with the chemistry education community the rubrics used to evaluate student videos associated with using a pipet, using a buret, and making a solution in a volumetric flask that were part of a digital badging project. The rubrics were used across multiple general chemistry courses, hundreds of teaching assistants, and…

Kylie L. Luska – Journal of Chemical Education, 2022
A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

Budner, Drew; Simpson, Brett – Journal of Chemical Education, 2018
Students entering into a quantitative analysis course often struggle with connecting theoretical aspects of concepts from lecture to hands-on applications in the laboratory setting. A one-semester quantitative analysis course was redesigned to integrate active learning with a project-based curriculum that incorporated structured review of…

Simpson, Tyler; Chiu, Yu-Chun; Richards-Babb, Michelle; Blythe, Jessica M.; Ku, Kang-Mo – Biochemistry and Molecular Biology Education, 2019
Allelopathy plays crucial roles in invasive plant viability and agricultural production systems. However, there is no well-established hands-on learning activity to teach the concept of allelopathy. Nor is there an activity which allows students to gain knowledge about glucosinolates and their corresponding enzyme, myrosinase, which are present in…

Sedwick, Victoria; Leal, Anne; Turner, Dea; Kanu, A. Bakarr – Journal of Chemical Education, 2018
The monitoring of metals in commercial products is essential for protecting public health against the hazards of metal toxicity. This article presents a guided inquiry (GI) experimental lab approach in a quantitative analysis lab class that enabled students' to determine the levels of aluminum in deodorant brands. The utility of a GI experimental…

Towns, Marcy; Harwood, Cynthia J.; Robertshaw, M. Brooke; Fish, Jason; O'Shea, Kevin – Journal of Chemical Education, 2015
An evidence centered design approach was used to develop, implement, and assess a novel and innovative digital pipetting badge using Purdue's Passport system. Each student in a large lecture course created a video demonstrating how to use a 10 mL pipet to dispense liquid. The video was uploaded into the Passport system, which allowed instructors…

Gupta, Tanya – ProQuest LLC, 2012
Recent initiatives in the laboratory curriculum have encouraged an inquiry-based approach to learning and teaching in the laboratory. It has been argued that laboratory instruction should not just be hands-on, but it should portray the essence of inquiry through the process of experiential learning and reflective engagement in collaboration with…
