Direct linkMichael, Joel; Modell, Harold – Advances in Physiology Education, 2019
We have created and validated a conceptual framework for the core physiology concept of "cell membrane." The conceptual framework is composed of 27 items arranged in a hierarchy that is, in some instances, four levels deep. We have validated it with input from faculty who teach at a wide variety of institutional types. All items making…

Nagel, Thomas; Mentzer, Casey; Kivistik, P. Mike – Journal of Chemical Education, 2019
This experiment provides students with a thorough understanding of electrolysis and the parameters that most greatly impact optimization of this process. In this laboratory exercise, students will focus on the anodization of bismuth metal to develop thin oxide films. When designing an electrolytic cell devoted to anodization, there are several…

Hernandez Cardenas, Lizette Susana; Castano, Leticia; Cruz Guzman, Cristina; Nigenda Alvarez, Juan Pablo – Australasian Journal of Educational Technology, 2022
This study's innovative objective was to develop a personalised learning model to equate students' entry level knowledge as they entered the School of Medicine and Health Sciences at Tecnologico de Monterrey in Mexico in 2019. This was necessitated by a difference in the depth and approach to preparatory content. The methodology focused on…

Salinas, Dino G.; Gallardo, Mauricio O. – International Journal of Mathematical Education in Science and Technology, 2022
Biological systems exhibit strong dynamic variations; for example, a system may have a tendency towards either a steady state, periodic behaviour or chaotic oscillations. These findings, explained by dynamic systems theory, have allowed researchers to formally relate a wide variety of systems, such as the theory of rumour propagation, glucose…

Kim, Youngshin; Lee, Yun-hye; Lee, Hyonyong; Lim, Soo-min – Journal of Biological Education, 2023
This study examined a network of concepts used in the curriculum, textbooks, instruction, and assessment in relation to somatic cell division and investigated the alignment of science concepts used in them. Textbooks and teachers' instruction and evaluation questions were collected to analyse the alignment between the concepts and the conceptual…

A set of core concepts ("big ideas") integral to the discipline of physiology are important for students to understand and demonstrate their capacity to apply. We found poor alignment of learning outcomes in programs with physiology majors (or equivalent) from 17 Australian universities and the 15 core concepts developed by a team in the…

Kattmann, Ulrich – School Science Review, 2018
Should entropy and energy be emphasised as relevant concepts for biology education? This question will be discussed, highlighting the ways in which the concepts of entropy and energy can contribute to a better understanding of biological processes. Organisms are open systems. Therefore, the chosen perspective is different from the traditional…

Polcic, Peter – Journal of Chemical Education, 2018
In biochemistry, the trivial names of chemical compounds constitute a significant part of scientific language. Understanding the etymology of the names may be important for the association of these names with actual compounds and thus be a valuable teaching tool. The citric acid cycle (Krebs cycle) is a central metabolic pathway in most living…

Metabolic control analysis (MCA) is a promising approach in biochemistry aimed at understanding processes in a quantitative fashion. Here the contribution of enzymes and transporters to the control of a given pathway flux and metabolite concentrations is determined and expressed quantitatively by means of numerical coefficients. Metabolic flux can…

Julio G. Soto; Rachael French; Sulekha Anand – Biochemistry and Molecular Biology Education, 2024
We developed an advanced, year-long course sequence in eukaryotic cell and molecular biology in order to increase conceptual understanding. Three years of historical data from a one semester, traditional-lecture, senior cell and molecular biology course (n = 237) were compared with 3 years of data collected from the year-long course sequence (n =…

Halpin, Patricia A.; Gopalan, Chaya – Advances in Physiology Education, 2021
Certain physiology concepts can be difficult for students to understand, and new strategies need to be implemented to teach these concepts. Cell signaling is a core concept in physiology and is presented to undergraduate students starting with their first-year Principles of Biology course. Flipped teaching (FT) combined with dramatizations were…

Benjamin David; Faisal Masood; Karin Jensen – Biomedical Engineering Education, 2021
The transition to remote learning in response to the COVID-19 pandemic necessitated the adaptation of an in-person cell culture lab practical to a virtual assessment in an introductory biomedical engineering lab course. The virtual lab practical was administered in the course LMS and implemented video, data analysis, and multiple-choice questions.…

Coleman, Aaron B.; Lorenzo, Kyla; McLamb, Flannery; Sanku, Abhiraj; Khan, Sahil; Bozinovic, Goran – Biochemistry and Molecular Biology Education, 2023
Effectively teaching scientific reasoning requires an understanding of the challenges students face when learning these skills. We designed an assessment that measures undergraduate student abilities to form hypotheses, design experiments, and interpret data from experiments in cellular and molecular biology. The assessment uses…

Jones, Jeff C.; Bassett, Gennie M.; Lescalleet, Jacob L.; Wingert, Jason R. – Journal of Biological Education, 2023
CRISPR technologies are among the most powerful advancements in modern biology because they accurately manipulate the genomes of living cells and have the potential of curing various genetic diseases. This study examined the attitudes of undergraduate health science students towards somatic cell and germline gene editing therapies and whether…

Understanding molecular processes and coordinating the various activities across levels of organization in biological systems is a complicated task, yet many curricular guidelines indicate that undergraduate students should master it. Employing mechanistic reasoning can facilitate describing and investigating biological phenomena. Biofilms are an…
