Understanding how individual students cognitively engage while participating in small group activities in a General Chemistry class can provide insight into what factors may be influencing their level of engagement. The Interactive-Constructive-Active-Passive (ICAP) framework was used to identify individual students' level of engagement on items…

This computer game was designed and developed to enhance the skills of high school students in balancing chemical equations. The game simulates a trip to the beach and consists of three missions, ranging from easy to difficult levels, enabling players to engage in a contextual learning experience. The objectives of this computer game development…

Machine learning (ML) is extensively applied in chemistry, particularly in vibrational spectroscopy. However, few teaching examples effectively demonstrate the capabilities of ML in classifying polymeric materials, exhibiting subtle spectral differences that elude visual discrimination. This study presents a teaching example specifically tailored…

Our goal as educators should be to help our students become well positioned to achieve future success. To develop effective strategies for accomplishing this objective, we must first understand the root causes of success. Thus, to best serve undergraduate students who are taking organic chemistry courses, we must understand the attributes that…

The effects of kinetic vs thermodynamic control on "endo"/"exo" stereoisomer ratios can be observed in a simple Diels-Alder reaction between "N"-phenylmaleimide and furan. The use of microwave-promoted synthesis affords the cycloadducts in yields ranging from 65-100%, employing reaction times of 1-10 min at…

The synthesis of 4-amino-3-nitrobenzoic acid methyl ester is a simple Fischer esterification reaction designed as an experiment for use in an introductory organic chemistry course. The compound was synthesized as a one-pot reaction within 30 min to 16 h, with 1 h producing a workable yield. The bright-yellow solid was purified using liquid--liquid…

The acquisition of quantitative measurement data has been a challenge in chemistry education for a long time, as the required measurement devices are often too old, error-prone, complicated to operate, or simply too expensive. This paper presents the LabPi digital measurement station, which addresses this problem and provides a solution for…

Conventional mobile phone colorimetry usually utilizes the RGB color mode to measure concentration of solutions, but the paper entitled "Determining the Amount of Copper(II) Ions in a Solution Using a Smartphone" proposes the use of hue ("H") to measure the concentration. It is pointed out that the "H" value increases…

A parallel series of general chemistry courses for Life Science Majors was created in an effort to support students and improve general chemistry outcomes. We created a two-quarter enhanced general chemistry course series that is not remedial, but instead implements several evidence-based teaching practices including Process Oriented Guided…

The importance of introducing students to mechanistic reasoning (MR) early in their schooling is emphasised in research. The goal of this case study was to contribute with knowledge on how early primary students' (9-10 year-olds) MR in chemistry is expressed and developed in a classroom practice framed by model-based inquiry. The study focuses on…

Different goals of high schools and vocational schools in Indonesia become the main factor causing the distinction of preparedness of chemistry teachers in using the Science, Technology, Engineering, and Mathematics (STEM) approach in their teaching. Yet the High School Chemistry Teachers (HSCT) and Vocational School Chemistry Teachers (VSCT) need…

Holism evolution states that although energy, matter, life, consciousness and the human personality are independent and different substances/levels of evolution, they are holistically and intimately related. This paper presents the findings from teaching chemistry to high school science students and post-graduate university science-education…

Though job opportunities in science, technology, engineering, and math (STEM) continue to expand in the United States, people on Individualized Education Programs (IEPs) while in school are continually disadvantaged in future STEM-based career possibilities. Studies have shown that students on IEPs are far less likely to major in a STEM degree…

Data are an essential factor in the fourth industrial revolution, demanding engineers and scientists to leverage and analyze their potential for significantly improving the efficiency of industrial processes and their control systems. In classical industrial process control systems, the models are constructed using linear data-driven approaches,…

A new teaching resource comprised of raw X-ray diffraction data sets from crystallography experiments has been compiled. The aim of this resource is to provide a tool with which to plug the teaching gap between crystals and chemical structures present at various levels of education, as well as providing examples for early stage researchers and…
