Jichao Xue; Jiaxin Liu; Qingshu Yuan; Zhengwei Yao; Jin Xu; Zhigeng Pan – Education and Information Technologies, 2025
To optimize learning experience and improve learning performance, current virtual experimental systems usually assist students with stepwise guidance before operations and feedback after them. However, stepwise and excessive guidance can lead to student overreliance, while late feedback cannot avoid potential errors during experimental learning.…

Prendergast, Aisling M.; Shanahan, Rachel; Hickey, Aobha; Harrington, Francis; Schönbauer, David; Byrne, Peter A.; Schnürch, Michael; McGlacken, Gerard P. – Journal of Chemical Education, 2020
In the past decade, C-H functionalization has been a very active topic of research in both academia and industry. When a H atom is replaced by an aryl (or heteroaryl) group, the transformation is termed "direct arylation". This approach to the formation of key (hetero)aryl-(hetero)aryl bonds is complementary to traditional methods, such…

Kumar, Amit; Mantri, Archana – Education and Information Technologies, 2022
Embedded system course requires the manifestation of acquired knowledge through the transfer of the relevant skill set in a hands on environment to achieve the respective course outcome. Laboratory skills provide the optimum exposure and experiential learning to obtain real time solutions for real time problems. The present embedded system course…

Gardner, Margery; Abrams, Neal; McGee, Gregory; Hogan, Elizabeth – Journal of College Science Teaching, 2022
This article explores results from a 3-year model of laboratory instruction, Project Synapse, that synthesized biology, chemistry, and communication curricula for firstyear science majors at a STEMfocused university. Laboratory biology-chemistry integration was featured at natural intersections where disciplines used similar tools, such as…

Kearns, James K.; van der Wielen, Matthew – Journal of Chemical Education, 2021
By focusing on food and a pervasive contaminant, this experiment engages student interest and effort while providing essential instruction and experience. As institutions are challenged by existing and emerging budgetary constraints, this experiment offers a determination approach employing commonly available instrumentation, the graphite furnace…

Hosbein, Kathryn N.; Lower, Meghan A.; Walker, Joi P. – Journal of Chemical Education, 2021
Current research suggests that students often fail to focus equally on the three aspects of scientific argumentation (cognitive, epistemic, and social) when they are given an opportunity to engage in argumentation. This study examined student argumentation within a two-semester general chemistry laboratory sequence at East Carolina University to…

Stewart, John F.; Gustafson, John E.; Moore, Michael E.; Forshee, J. Lance; Canaan, Patricia; French, Donald P. – American Biology Teacher, 2023
Students who experience research as undergraduates tend to remain in science, technology, engineering, and mathematics fields. Since course-based undergraduate research experiences (CUREs) are often expensive to implement, we developed a relatively inexpensive first-semester research course for majors entitled "Freshman Research in…

Wellhofer, Larissa; Luhken, Arnim – Journal of Chemical Education, 2022
Problem-based learning (PBL) is an acclaimed educational concept for laboratory teaching in chemistry, which significantly affects learner motivation. A central aim of PBL is to overcome educational problems with "cook-book" laboratories. For example, when students receive experimental instructions and apply the instructions similar to…

Kong, Sunnie; Kumta, Shruti; Vardar-Ulu, Didem – Biochemistry and Molecular Biology Education, 2022
The COVID-19 pandemic emphasized the importance of peer communication networks for student outcomes. Herein, we describe the use of supplemental instructional videos created by former students and integrated into electronic lab notebooks, to restore the lost community-learning component using student voices in a de-densified upper-division…

Alexander Grushow – Journal of Chemical Education, 2022
A revised version of a traditional physical chemistry laboratory experiment has been developed to enhance student discussion in the laboratory and to improve students' connections between physical chemistry concepts and real molecular systems. In this experiment, students explore the keto-enol tautomerization of 2,4-pentanedione. However, unlike…

Pufall, Miles A.; Wilson, Anne M. – Biochemistry and Molecular Biology Education, 2020
Providing students with training in advanced laboratory skills is an essential part of scientific education. At the same time, engaging students in research is becoming equally important. Classroom-based undergraduate research experiences (CUREs) have emerged to fill this need, and can take many forms. In this article we describe reengineering an…

Duerden, Amanda; Moon, Nicole; Grubbs, G. S., II – Journal of Chemical Education, 2021
Few laboratory exercises exist that introduce undergraduate students to both the concepts and instrumentation used in rotational spectroscopy. Because of this gap in undergraduate laboratory training, a teaching laboratory for the pure rotational spectroscopy of benzonitrile has been developed and reported. Owing to benzonitrile's recent discovery…

Keiner, Liz; Graulich, Nicole – Chemistry Education Research and Practice, 2021
Understanding ongoing chemical processes in the laboratory requires constant shifting between different representational levels--the macroscopic, submicroscopic, and symbolic levels--and analysis of the various mechanistic features of each of these levels. Thus, the ability to explain observations of chemical phenomena with regard to their…

Porter – Biochemistry and Molecular Biology Education, 2024
For close to 2 years, we have witnessed the impacts of the SARS-CoV-2 pandemic on research at several different levels. Among the list, limited access to laboratory-based training for undergraduate students prevented this cohort from gaining exposure to the realities of a research laboratory at a critical time in training when they may have found…

Park, Kunsoon; Park, Narang; Heo, Wookjae – Journal of Education for Business, 2019
When developing effective training programs, it is important to know students' expectations of laboratory classes. The authors collected 170 surveys from students in one laboratory class to investigate the underlying dimensions of their expectations of training. Factor analysis identified the following six dimensions of students' expectations:…
