Manzanares, Amanda D.; Anderson, Steven W.; Pugh, Kevin J. – Journal of Geoscience Education, 2023
The mineral identification lab is typically the entry level college student's initial hands-on introduction to minerals. Our research focused on identifying alternative mineralogy conceptions that students bring to an introductory geology course and investigating the origins and nature of these conceptions. We identified a number of alternative…

Mauna S. Kareti; William J. Howitz – Journal of Chemical Education, 2023
Normal phase thin layer chromatography is a widely taught technique in undergraduate organic chemistry laboratory courses. To understand how the technique works, students must have a strong conceptual understanding of polarity and intermolecular forces. Unfortunately, many students have misconceptions regarding how polarity and intermolecular…

Teresa Celestino; Dora Stella Lombardi – Journal of Chemical Education, 2024
Italian high school students carried out some activities within career guidance actions organized by the Department of Chemistry of Sapienza University (Rome) in order to promote enrollments in a chemistry Bachelor's course, thus remedying the shortage of professional chemists. Novel didactic sequences have been designed to facilitate the…

Emiliano Foresto; Fiorela Nievas; Walter Giordano; Pablo Bogino – Journal of Biological Education, 2024
The curriculum for undergraduate Agricultural Engineering does not usually include much laboratory practice. In order to address this, here we propose the design of a practical class on legume-rhizobia symbiosis, using an interdisciplinary approach that takes elements from botany, agriculture, and microbiology. The students perform an assay to…

Enhancing Teaching Effectiveness in Biochemistry Labs: Author Reflections and Improvement Strategies
Maurizio Costabile; Bradley Simpson; Jasmina Turkanovic; Bernard P. Hughes – Biochemistry and Molecular Biology Education, 2024
This article details the outcome of a joint reflective approach undertaken by the authors to identify common difficulties experienced by 2nd-year undergraduate Biochemistry students in laboratory classes. Difficulties experienced in laboratories can affect the development of hand skills, an understanding of how to correctly operate laboratory…

Davor Cotoras – Biochemistry and Molecular Biology Education, 2024
The utilization of computer simulators in university education is progressively being embraced to offer students a practical exposure to industrial bioprocesses. Bioreactor computer simulators hold various advantages over conventional laboratory experiments, such as cost-effectiveness and enhanced safety. The research objective is to assess the…

Stephanie M. Breen; Jesse McCain; Josipa Roksa – Higher Education: The International Journal of Higher Education Research, 2024
Prior literature has documented the importance of faculty advisors in the doctoral student socialization process, with a few studies describing negative advising relationships characterized by disengagement, disinterest, unsupportive behavior, and interpersonal conflict. We extend this research by exploring how negative advising relationships…

Irina Braun; Nicole Graulich – Chemistry Education Research and Practice, 2024
Resonance is a crucial concept in Organic Chemistry that enables both deriving chemical properties from molecular structures and predicting reactions by considering electron density distribution. Despite its importance for problem-solving and learning success, learners encounter various difficulties with this concept. Although prior research…

K. K. Mashood; Arvind Kumar; Anwesh Mazumdar – International Journal of Mathematical Education in Science and Technology, 2024
Working with approximations is a common practice in physics. This paper presents an exploratory study of student understanding of some of the elementary aspects of approximations encountered in college physics. For this purpose, a questionnaire (a set of 14 multiple-choice questions) was developed to probe how students dealt with these aspects in…

Barton, Callie; Gasaway, Katherine Clohan; Islam, Rejaul; Aziz, Tarfi; Krewall, Jessica; Punthrangkul, Devon; Willian, Kyle R. – Journal of Chemical Education, 2022
This paper describes the development of a fully remote upper-class biochemistry lab course. The sudden change to online teaching in the middle of spring semester 2020 had a primarily negative impact on laboratory teaching. These effects were mitigated because the students had done many of the basic hands-on procedures before the switch. A true…

May, Jason Michael – ProQuest LLC, 2022
Undergraduate physics laboratory curriculum has undergone significant modification in recent decades in response to research and recommendations from educational and professional organizations and stakeholders. These reforms address multiple issues, such as 1) lack of student agency in experimentation, 2) an incomplete framework for student…

Thy, Savrin; Iwayama, Tsutomu – Physics Education, 2022
Viscous and Coulomb's friction combined contribute to the damping of a pendulum; however, they are usually treated as a silo effect. In this study, we investigate the combination of viscous and Coulomb damping in compound pendulum oscillation, employing two modern instruments that are cheap and handy to quantify the experiments, which are video…

Mananghaya, Michael Rivera; Yu, Dennis – Physics Education, 2022
A low-cost simple one-dimensional spring-mass system was constructed to investigate damped oscillations. The suspended mass in the system can move freely inside a cylinder containing a fluid. It provides an in-depth experience for demonstrating various concepts under oscillations. It can be used to probe the magnitude of damping forces in liquids…

McGregor, Sarah L.; Pleasants, Jacob – Physics Education, 2022
Refraction is a foundational concept within introductory physics. Physics students need a deep understanding of refraction, including Snell's Law, in order to progress towards more complex optics topics such as lenses and images. Unfortunately, many physics students obtain only a superficial understanding of refraction. Although many students can…
