The three-dimensional nature of macromolecules is often difficult for undergraduate students to grasp. This leads to difficulties in understanding key concepts in Biochemistry, such as protein function and conformational change. Virtual reality (VR) technologies, which can aid students in three-dimensional visualizations, have been shown to…

This paper uses the questionnaire to evaluate the current status of laboratory safety perceptions, willingness, and efforts of first-year undergraduates at the School of Chemistry and Chemical Engineering, Tianjin University of Technology. The survey includes a sample size of 360 undergraduates covering four chemistry-related majors. The…

Low-dimensional materials especially graphene-based are of high interest to a broad community. One of the most fundamental aspects in the biomedical field is material characterization, which helps understand their property and tune for application. Though the existing teaching curricula are well standardized to include basic principles and…

One approach that has been gaining significant attention among chemistry education scholars and practitioners is the employment of game-based learning to teach least-learned and difficult topics at various educational levels. One reason for this is that it promotes active, constructive learning and makes learning science a fun experience through…

Encouraging student engagement is a key aim in any educational setting, and allowing students the freedom to pursue their own methods of solving problems through independent experimentation has been shown to markedly improve this. In many contexts, however, allowing students this flexibility in their learning is hampered by constraints of the…

Recent instructional reforms in science education bring a new vision that aims to move science teaching away from a focus on discrete facts covered at a superficial level to a focus on a smaller number of disciplinary core ideas that can be explored in depth. The success of these reforms depends on the instructional quality in science classrooms.…

This paper has a didactic aim. Indeed, starting from the well-known principle of free fall discovered by Galileo Galilei, we want to make some reflections that we consider useful for secondary school students. Being the acceleration invariant with respect to Galilei's transformations, it is useful to underline that the free fall in a gravitational…

In this study, we describe a method to employ a conventional compound light microscope, usually available in laboratories, to obtain fluorescence. In particular, two pieces of colored acrylic plastic were utilized to assist the microscope in filter performance. We also attempted to examine the applicability of the setup by staining onion cells…

Apparatus catalogues of the first half of the 20th century contain a number of clever and simple devices for measuring the index of refraction of a liquid. In some cases students can put together one of these pieces of apparatus and then make their own measurements. The Gilley board was one of the devices that caught my eye, and I would like to…

It has been well documented that for many students science is difficult to learn. Thus, as a food chemistry teacher, it has been my mission to continually search for and implement better ways to help my students learn chemistry. One strategy for improved learning, based on Johnstone's Triangle, that has been shown to be exceedingly effective, is…

Understanding the nature of science and scientific inquiry constitute foundation stones in scientific education in general and in scientific literacy in particular. Therefore, students must develop informed perceptions regarding science inquiry in order to be scientifically literate. The current study's purpose was to examine students' perceptions…

Potassium tris(oxalato)ferrate(III) trihydrate is a commonly prepared coordination compound in general or upper-level chemistry laboratories and can be recycled to grow large single crystals that instructors may display when introducing the experiment to classes. Showing the crystal's shape can also be used to briefly introduce students to X-ray…

We have developed a course-based undergraduate research experience (CURE) that can be carried out in the context of an existing second-semester or upper-level organic laboratory course. In this three-week laboratory module, students synthesize a small library of molecules, test them in a robust biological assay, and design a new compound library…

The formation of waves as used for surfing close to the shore is described and explained, and linked to other wave topics that are covered in school science. Of course, there are differences because the wave activity is influenced by many factors, such as the weather and the shape of the shoreline, which make the wave patterns much more…

Many newsworthy events have brought with them scientific developments that have furthered the knowledge and understanding of the world and impacted life today. Events such as these can provide the perfect way to link history with science and provide children with the opportunity to make the connection between science and everyday life. As Primary…
