Teaching biochemistry well is not an easy job for teachers and so is learning biochemistry well for students. Just as many students often complain, they virtually always fail in either physiology or biochemistry. I have been teaching biochemistry at Nanjing University for over 25 years and am very successful in my biochemistry-teaching career. The…

Mentoring to many is the informal highly unstructured teaching, advising, and nurturing which we receive from various individuals during our school years and professional lives and then give back to our students and more junior colleagues. However, with the advances in science and technology, the increasing competitiveness in the workplace, fast…

Although science education, including biochemistry and molecular biology education, starts before students commence university, for many students, undergraduate programs are their first real introduction to biochemistry and molecular biology. Students often report that biochemistry and molecular biology are relatively difficult topics hence the…

Since 2013, the number of publications on flipped learning within chemistry have steadily increased. However, most of these studies focus on flipped course reforms within individual institutions, while the outcomes of any learning environment are dependent on how the environment is structured and the degree to which students interact with its…

The recent works of oscillators are mainly focused on underdamped oscillation. Therefore, the writer proposes an experimental apparatus to demonstrate all types of damped harmonic oscillation. The apparatus utilizes an Arduino for data acquisition and an Excel spreadsheet for data analysis. By using this apparatus, the type of damped harmonic…

In recent years, general relativity (GR) and gravitational-wave astronomy have emerged both as active fields of research and as popular topics in physics classrooms. Teachers can choose from an increasing number of modern instructional models to introduce students to relativistic ideas. However, the true potential of an instructional model can…

Light emitting diodes have been used to determine Planck's constant in introductory physics laboratories. One common method relies on the energy of the light emitted by the LED and its relation to the energy gap in the solid of which the diode is composed. However, there could be a problem with the data that are collected for this experiment. For…

Human anatomy knowledge is a core requirement for all health care clinicians. There is a paucity of information relating to anatomy content and delivery in Australian chiropractic programs. The aim of this study was to describe anatomy teaching in Australian chiropractic programs, utilizing a survey which was distributed to all four programs,…

Electrocatalytic hydrogenation of acetol (IUPAC: 1-hydroxy-2-propanone), a species formed upon thermal liquefaction of biomass, can be achieved using inexpensive objects: filter paper, coins, batteries, salts, and water. This simple example demonstrates that "green" chemical transformations can be achieved with familiar items and helps…

The detailed analysis and scoring of concept maps may not be necessary in order for students to gain from their use in the classroom. A simplified recognition of different types ('species') of map may increase the likelihood of teachers employing maps in their classrooms so that more teachers and students might benefit from concept mapping on a…

In this article, we examine the rotation angle dependence of a hand-made fan-type variable capacitor for use in physics experiments in university classes. We made two circular bakelite plates, and the two terminal plates of the capacitor were 90° fan-type copper disks. The capacitance varied linearly with the rotation angle. The standard deviation…

We demonstrated the fabrication of a low-cost and high-resolution papercraft smartphone spectrometer and characterized its performance by recording spectra from gas discharge lamps. The optical design and a lab-made narrow slit used in the fabrication led to fine images of the slit on the image sensor, resulting in high spectral resolution. The…

Radical chemistry is an essential part of the organic chemistry curriculum. Free radical halogenation experiments provide an excellent opportunity to introduce important topics related to the outcome and mechanism of organic reactions. In this communication, a green photochemically activated benzylic bromination of p-toluic acid is described. In…

The prompt transfer of cutting-edge science into students' curricula is a challenging task. Often research experiments are too complex or expensive to be translated into a secondary or tertiary education setting. Herein, we introduce a laboratory experiment that translates the recently developed research technique of a wavelength dependent,…

Examination of my students' individual gains on the Force Concept Inventory (FCI) over the course of several semesters led to the realization that student pretest knowledge on certain key questions appeared to be correlated to enhanced gain during the class. Acting under the hypothesis that early intervention aimed at helping the class perform…
