The galvanic cell is a basic concept in electrochemistry. To assess mainland Chinese students' proficiency levels in galvanic cells, the Galvanic Cell Proficiency Level Assessment (GCPA) was developed based on the Rasch model. The GCPA was developed through a pilot test and consists of seven multiple-choice questions and four open questions. The…

Ivan Mijakovic; Shadi Rahimi – Biochemistry and Molecular Biology Education, 2024
To evaluate the impact of active learning approaches in a basic molecular and cell biology course for undergraduate students, we assessed the effect of learning by teaching and peer review on the learning outcomes. A literature seminar activity with peer review and feedback was organized as a compulsory activity for all students, covering about…

Mahaffey, Angela L. – Advances in Physiology Education, 2023
This article will (1) initially outline first-year nursing and undergraduate exercise sciences student perspectives on examinations of the 2011 Michael-McFarland (M-M2011) core principles in physiology through an anonymous online survey, and (2) model an updated approach based on these qualitative findings. Briefly, for the first perspective (i of…

Ball, Karen L. – Advances in Physiology Education, 2023
As one element of an extensive revision to program curriculum, the Integrative Physiology and Health Science Department at a small, private, liberal arts institution developed a novel introductory course for the major, focusing specifically on the "core concepts" of physiology. Intended to provide the initial step in explicit scaffolding…

A deeper understanding of what factors influence metacognition has never become more pressing than in today's digital era, in which information flows constantly and quickly. To this end, the present study explored the role of culture in mediating how individuals experience metacognitive phenomena. For this purpose, the International Group on…

The purpose of this study was to investigate whether the science activities supported by the Web 2.0 tools at the 7th-grade secondary school level had an impact on the students' academic achievement, visual literacy level and spatial visualization skills. The study was designed in accordance with the nonequivalent control group design. The study…

Biological interactions and associations underlie life's processes at every level of organization. Here, we present a classroom activity that allows students to visualize and understand the connections within almost any biological system, from cell functions to ecological relationships. We recommend that instructors implement this activity to…

Fry, Benjamin R.; Pence, Nathan T.; McLocklin, Andrew; Johnson, Alexander W. – Learning & Memory, 2021
The dopamine system has been implicated in decision-making particularly when associated with effortful behavior. We examined acute optogenetic stimulation of dopamine cells in the ventral tegmental area (VTA) as mice engaged in an effort-based decision-making task. Tyrosine hydroxylase-Cre mice were injected with Cre-dependent ChR2 or eYFP control…

Senter, Philip J. – American Biology Teacher, 2021
The recent discovery of preserved cells and soft tissues in certain dinosaur bones seems incompatible with an age of millions of years, given the expectation that cells and soft tissues should have decayed away after millions of years. However, evidence from radiometric dating shows that dinosaur fossils are indeed millions of years old. Under…

Stem cells are cells that can self-renew and differentiate into a variety of cell types under certain conditions. Stem cells have great potential in regenerative medicine and cell therapy for the treatment of certain diseases. To deliver knowledge about this frontier in science and technology to medical undergraduate students, we designed an…

Autism spectrum disorder (ASD) is manifested by abnormal cell numbers and patches of gene expression disruption in higher-order brain regions. Here, we investigated whether layer-specific changes in glia/neuron ratios (GNR) characterize patches in the dorsolateral prefrontal cortex (DL-PFC) of children with ASD. We analyzed high-resolution digital…

An organic solar cell fabrication kit has been developed for demonstration in both undergraduate teaching classes and high school laboratories to promote the growing field of renewable energy and to facilitate empirical comprehension of solar technology. The laboratory focuses on fabricating organic photovoltaics (solar cells) and testing the…

Arguel, P.; Massiot, I. – Physics Education, 2020
Today, solar cells are very familiar to the broad public, and everyone has noticed their particular geometry resembling a square with rounded-off corners. However, the rationale behind this geometry is little known. This paper presents a precise study of the geometry of silicon solar cells and its evolution since their appearance in the early…

Over the past decade, the development of three-dimensional mammalian cell organization--called human organoids--from stem cells has provided a framework for future clinical therapies. As human organoid research progresses, we also need to keep in mind the cross-cultural and ethical dimensions of human organoids research. Our review article aims to…
