Ubiquitin is essential for eukaryotic life and varies in only 3 amino acid positions between yeast and humans. However, recent deep sequencing studies indicate that ubiquitin is highly tolerant to single mutations. We hypothesized that this tolerance would be reduced by chemically induced physiologic perturbations. To test this hypothesis, a class…

Nanostructures of organosilanes, thin metal films, and protein nanopatterns were prepared and analyzed with atomic force microscopy (AFM). Organosilanes with designed functional groups were used to selectively pattern green fluorescent protein at the nanoscale using protocols developed with particle lithography. Mesospheres are deposited onto a…

This article presents a study conducted at Georgia Gwinnett College (GGC) to explore the use of ChatGPT, a large language model, for fostering critical thinking skills in higher education. The study implemented a ChatGPT-based activity in introductory chemistry courses, where students engaged with ChatGPT in three stages: account setup and…

The effectiveness of animal physiology practical book based on guided inquiry model is the essential factor to achievement student understanding a about animal physiology concepts. The purpose of this study was to observe the effectiveness of animal physiology practical book based on guided inquiry model in Padang State University. The variables…

Mass spectrometry is frequently introduced to undergraduate students as an instrument for both qualitative and quantitative chemical analysis. One of the most common uses of mass spectrometry (MS) is to deduce or confirm a compound's chemical formula, by relying on high-resolution accurate-mass measurements. However, like all forms of instrumental…

"Mathematics Across the Sciences" is an applications-based course designed to strengthen students' mathematical skills in preparation for calculus or for a major in the sciences. Its development relied heavily on input from faculty members in several science departments. This article describes the course; many of the scientific…

Purpose: This paper aims to discuss the knowledge levels, attitudes and behaviours regarding the concept of sustainable development among pre-university programme educators, as well as the potential barriers and opportunities they face in adopting the concept of sustainable development in the teaching of the pre-university level chemistry module…

Evidence of the effectiveness of active learning has resulted in a shift in post-secondary classrooms towards student-centred teaching, often relying heavily on peer-to-peer interactions. While the overall benefit of these teaching methods is established, it remains unclear whether all sub-populations of students benefit similarly. Given the…

Here we present an inexpensive proposal to experimentally study Faraday's law of induction. The experiment uses low-cost materials, a computer with a sound card and a smartphone, both running free software. A value proportional to the induced electromotive force is measured with the computer's sound card and the data related to the magnetic field…

The application of social network analysis (SNA) has recently grown prevalent in science, technology, engineering, and mathematics education research. Research on classroom networks has led to greater understandings of student persistence in physics majors, changes in their career-related beliefs (e.g., physics interest), and their academic…

Board games continue to increase in popularity and the pedagogical value of games has been repeatedly supported. Games keep students engaged and the level of engagement translates directly into time spent playing, and correspondingly, time spent reviewing course material. Therefore, game play is expected to result in greater student success.…

This paper describes a high school or introductory university course in scientific programming that introduces the computer revolution into the physics curriculum at the beginning. In the first one-hour lecture, Euler's method is presented and used to compute a solution to the analytically unsolvable two-body problem. In the remainder of the…

Project-based learning units are often used for large scale work integrated learning (WIL) experiences in Liberal Studies Degrees as they offer scalability and sustainability of delivery to large cohorts. This systematic search and review evaluates the effectiveness of interdisciplinary project-based learning in Science Degree programs for…

The use of machine learning and data mining techniques across many disciplines has exploded in recent years with the field of educational data mining growing significantly in the past 15 years. In this study, random forest and logistic regression models were used to construct early warning models of student success in introductory calculus-based…

Students' responses to energy & momentum (EM) concepts were investigated. EM concepts are fundamental and crosscutting in physics. A standardized Energy and Momentum Conceptual Survey (EMCS) test were used to collect quantitative data from 108 first year science students enrolled in a university in Ethiopia. Concentration analysis was used to…
