Early research experiences play an important role in shaping students' academic and professional development and future career path. While many colleges and universities offer undergraduate students the chance to engage in research, a significant number of high school students face limited or no access to such opportunities. Initiatives such as…

Italian high school students carried out some activities within career guidance actions organized by the Department of Chemistry of Sapienza University (Rome) in order to promote enrollments in a chemistry Bachelor's course, thus remedying the shortage of professional chemists. Novel didactic sequences have been designed to facilitate the…

We describe an iodometric titration method for the determination of ascorbic acid using a microfluidic paper-based analytical device([mu]PAD). The ascorbic acid was detected by measuring the length of the blue band formed in a straight paper channel delimited by wax. This analytical method was designed as a laboratory experiment for under…

In this brief experiment, students create a superhydrophobic surface as an application of polar--nonpolar interactions and redox chemistry. Half of a zincgalvanized steel strip is coated in copper nanoparticles through electroless deposition. A layer of nonpolar octadecanethiol is added to half of that copper surface. Students classify the three…

A common misconception about dissolving is that heating and/or stirring are required for the dissolving process to occur. In this study, quantitative experimental evidence was collected and analyzed to demonstrate that neither heating nor stirring is required for dissolving. Educators can use the data and results in this study to address this…

Chromatography is a ubiquitous technique in analytical chemistry, and high-performance liquid chromatography (HPLC) is the industry standard for quantitation of components in solution mixtures. However, demonstrating the principles of liquid chromatography to undergraduates via HPLC-based experiments often proves ineffective because of the fully…

In a normal year approximately 3 months pass between students taking their final examinations in high school or college and beginning an undergraduate course in chemistry. In the months prior to those examinations, students will usually have undertaken an extensive period of revision and consolidation of the key concepts learned throughout their…

To promote the integration of aesthetic education into chemistry education, this study designed activities to photograph precipitation reaction experiments with a smartphone, thereby combining experimental inquiry with artistic creation across disciplines. These activities were divided into (i) perceiving, (ii) appreciating, (iii) exploring, and…

Mass spectrometry is one of the few instrumental analysis techniques that can be relatively well-understood with physics/chemistry knowledge typical of an advanced high school or a beginning undergraduate student. This positions mass spectrometry well to be used as a bridge between abstract concepts typically set as learning goals in courses at…

This article describes the development of the Quantization and Probability Representations Inventory (QuPRI) as a measure of student understanding of the electron structure of the atom. The QuPRI was created using a mixed-method sequential design such that the items and distractors were generated on the basis of the analysis of semi-structured…

For the past 10 years, the Virtual Tournament of Chemistry, TVQ, has been held in Brazil, engaging high school students with challenging questions that require cooperation, effort, and a literature search, while exploring the advantages of the Internet as a tool for self-instruction. The tournament has worked both as a way of narrowing the gap…

Chemical reactions far from equilibrium can exhibit oscillatory behavior. Full understanding of this phenomenon is outside of the school curriculum. However, the importance of such processes in life sciences and peculiar spatial and temporal patterns accompanying the reactions can attract the attention of IB Diploma science students. They will…

The interface of art and science provides a broad range of educational and collaborative projects at various learning stages. Therefore, the use of historic artists' materials for teaching chemistry is receiving more attention. We prepared and used copper acetate (verdigris pigment) for a series of interconnected, lab-based activities, which can…

Video learning holds an important place in modern STEM classrooms, but more improvements to the learning experience are needed. In order to introduce active-learning components into assignments, questions are often deployed alongside videos. Unfortunately, many students tend to skip videos entirely and solely answer questions, bypassing valuable…

In the present theoretical study, we introduce the entropy concept into Chi's ontological shift theory. Chi distinguishes between two categories of process phenomena, direct and emergent, and claims that incorrectly considering emergent processes as direct ones is one of the sources of students' robust scientific misconceptions. The present study…
