Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…

A novel teaching approach is aimed at elucidating the concept of bond enthalpy for general chemistry students. Through the integration of a hands-on candy pulling activity, students in a large lecture class were provided a tangible experience to explore bond strengths using rope candy and a luggage scale. Feedback from students indicated a clear…

Teaching graduate students the entanglements of the interdisciplinary field of electrochemical DNA biosensors in microfluidics can be challenging, as it involves multiple fields of research strongly interacting with each other. Yet, electrochemical biosensors coupled with the improved hydrodynamics of microfluidics allow for simpler, more…

Students come into the classroom with a variety of background knowledge. Therefore, it is imperative that educators are able to help all students, regardless of their familiarity with the content. Since it can be challenging for some large enrollment classes to schedule recitation classes after lectures due to logistical constraints, this study…

To investigate the variation in active learning used in college science courses, the authors analyzed 57 comparison studies published in three prominent science education journals. Focusing on three sources of variation--(a) the active learning activities, (b) other pedagogical features, and (c) course structure/design--they found that most…

Concerns regarding students' difficulties with the concept of energy date back to the 1970s. They become particularly apparent for systems involving adenosine triphosphate (ATP), which plays a central role in maintaining the nonequilibrium state of biological systems and in driving energetically unfavorable processes. One of the most…

The great development of high-throughput molecular biology techniques and the consequent generation of massive data have made Bioinformatics essential for undergraduate Bioscience students. The importance of this scientific discipline is evidenced by the huge number of specialized publications, tools, and databases available. Training in…

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…

Many undergraduate chemistry and biochemistry students pursue careers in healthcare. Biomaterials, designed to harmonize with the complexity of the human body, have become increasingly significant in medicine as implants, drug delivery vehicles and tissue scaffolds. We believe it is essential that undergraduates are exposed to biomaterial…

This paper analyzes the relationship between the development of pedagogical innovation projects in experimental sciences and the establishment and evolution of Professional Learning Communities (PLC) in higher education, within an open innovation framework. To achieve this, an evaluative study employing a mixed-methods approach was conducted,…

There is a gap between the importance of certain archeological material sources and their perception, both by professionals and by the general public. Textiles, for example, are essential to understanding practices that marked daily life and rituals in the past, but they have often been extremely degraded over time, particularly in temperate…

Graduates in biology or genetics learn Mendel's laws and Hardy-Weinberg equilibrium as students, and they know, use, and sometimes teach these concepts. However, it is unusual to learn about stochastic processes during the graduate studies of these topics, although the applications of Markov chains in the fields of genetics or biology are…

Biochemistry, a complicated basic course in health sciences, plays a fundamental role in describing pathogenic mechanism of illness in molecular terms, and is required to be learned for all medical students. Due to various obstacles to biochemistry learning and teaching, there is a pressing issue of curriculum reform to arouse the student's…

We review the literature, from 2006 to 2020, focused on the teaching and learning of chemical bonding. The studies included in our review (48 studies set in 19 different countries overall) involved secondary and postsecondary students as well as K-12 teachers and university faculty. We synthesize these studies' findings to provide implications for…

Understanding organic reaction mechanisms can be a challenging task for many undergraduate students, particularly those who are nonchemistry majors, despite the fact that organic chemistry is a mandatory course for numerous science and engineering undergraduate programs. The selectivity of a reaction is largely determined by the distribution and…
