Jessie King; Barnaby Kelly; Nayla Rhein; Rhonda Rosengren – Biochemistry and Molecular Biology Education, 2024
To best prepare students for the real-world research environment, key skills, including experimental design, data analysis, communication of results, and critical thinking, should be key components of undergraduate science courses. Furthermore, the impact of the COVID-19 pandemic on in-person teaching has resulted in a need to develop courses that…

Preeti S. Kulkarni; Varuna S. Watwe; Sakshi S. Khatavkar; Akshay A. Khandagale; Sunil D. Kulkarni – Journal of Chemical Education, 2023
Flame Emission Spectroscopy (FES) is a powerful analytical technique widely used for identifying and quantifying elements in various samples. In this laboratory experiment, undergraduate students were introduced to FES and its significance in analytical chemistry. The experiment aimed to provide students with hands-on experience in constructing…

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…

Militello, Kevin T.; Nedelkovska, Hristina – Biochemistry and Molecular Biology Education, 2022
The COVID-19 pandemic has necessitated the need to reliably detect the presence of viral genomes in human clinical samples. The most accurate viral tests involve the use of qPCR. Thus, it is important for students to understand the mechanism to detect viral genomes by qPCR including critical qPCR controls and how to properly interpret qPCR data.…

Adrian Adams; Lauren Barth-Cohen – CBE - Life Sciences Education, 2024
In undergraduate research settings, students are likely to encounter anomalous data, that is, data that do not meet their expectations. Most of the research that directly or indirectly captures the role of anomalous data in research settings uses post-hoc reflective interviews or surveys. These data collection approaches focus on recall of past…

Patel, Parth H.; Conrad, Kristofer L.; Pathiranage, Anuradha L.; Hiatt, Leslie A. – Journal of Chemical Education, 2020
Given student familiarity with electronic cigarettes (e-cigs), this lab uses a student-built smoke collection apparatus to collect e-cig vapors to teach students about gas chromatography-mass spectrometry (GC-MS). Students in a second semester, introductory organic chemistry course spent 1 week collecting e-cig vapors and 1 week qualitatively…

Cole Jarvis Walsh – ProQuest LLC, 2021
Introductory physics lab instruction is undergoing a transformation, with increasing emphasis on developing experimentation and critical thinking skills. These changes present a need for standardized assessment instruments to determine the degree to which students develop these skills through instructional labs. In the first part of this thesis,…

Gal, Ya'akov; Uzan, Oriel; Belford, Robert; Karabinos, Michael; Yaron, David – Journal of Chemical Education, 2015
A process for analyzing log files collected from open-ended learning environments is developed and tested on a virtual lab problem involving reaction stoichiometry. The process utilizes a set of visualization tools that, by grouping student actions in a hierarchical manner, helps experts make sense of the linear list of student actions recorded in…

Hubler, Tina; Adams, Patti; Scammell, Jonathan – American Biology Teacher, 2015
The molecular basis of evolution is an important and challenging concept for students to understand. In a previous article, we provided some of the scientific background necessary to teach this topic. This article features a series of laboratory activities demonstrating that molecular events can alter the genomes of organisms. These activities are…

Hauri, James F.; Schaider, Laurel A. – Journal of Chemical Education, 2009
Sulfate reducing bacteria have been shown to be effective at treating acid mine drainage through sulfide production and subsequent precipitation of metal sulfides. In this laboratory experiment for undergraduate environmental chemistry courses, students design and implement a set of bioreactors to remediate acid mine drainage and explain observed…

DiBartolomeis, Susan M.; Mone, James P. – Cell Biology Education, 2003
Over the past decade, apoptosis has emerged as an important field of study central to ongoing research in many diverse fields, from developmental biology to cancer research. Apoptosis proceeds by a highly coordinated series of events that includes enzyme activation, DNA fragmentation, and alterations in plasma membrane permeability. The detection…
