Background/purpose: The current trend of training Chemistry teachers focuses on innovating pedagogical methods and developing students' holistic competencies, particularly their chemistry experimentation competencies (CEC). The CDIO (Conceive - Design - Implement - Operate) framework effectively combines theoretical knowledge with practice and…

Formative assessment has been proven to be highly effective in improving student understanding. Nevertheless, many instructors struggle to engage in this practice, particularly when working in large-enrollment classrooms. To facilitate and foster the implementation of formative assessment in chemistry courses, undergraduate students at our…

This is a fundamental and pedagogical work in quantum physics/chemistry, where we try to illustrate the Mulliken's question, "What are the electrons really doing in molecules?". And we also briefly review the development of the most popular numerical approaches in computational chemistry. We examine in a novel approach, how we can…

Three-dimensional symmetry plays a crucial role in crystallography education. The educational process can be facilitated by introducing the analysis of friezes and plane patterns such as parquets before presenting more sophisticated crystal structures. Analysis of the symmetry of parquets can serve as an opportunity to follow the full routine of…

The CHIMACTIV website (http://chimactiv.agroparistech.fr/) offers open educational resources related to analytical chemistry. It addresses a frequently encountered pedagogical issue: How can we encourage students to be more involved in learning during their courses (and especially during lab work) as well as provide a deeper teacher-learner…

Amides are usually prepared using amines and acyl halides, which often implies a two-step procedure. Alternatively, coupling reagents can be used in a single-step reaction with good yields, which seems to be suitable for organic chemistry laboratory classes. This work was designed to synthesize "N"-hexylcinnamamide through a one-step…

This activity allows students to visualize how to obtain different stoichiometries with various techniques in a single experiment. The involvement of three phases adds to the student's interest. Instructional materials are provided to facilitate the experimental procedures, interpretation of results, and error analysis. The reaction of Li from a…

The public image of chemistry is a relevant issue for chemical stakeholders. It has been studied throughout history by means of document analysis and more recently through surveys. Twitter, a worldwide online social network, is based on spontaneous opinions. We tried to identify the public perception of chemistry on Twitter, what it explains, and…

The complete structural analysis and resynthesis of an unknown compound, selected from a library of dipeptides, provided a framework for a course that built from expository experiments toward a guided-inquiry approach. We used this semester-long lab as a replacement for conventional second semester organic chemistry laboratory and successfully…

The American Chemical Society, Division of Chemical Education, Examinations Institute has been developing content maps for the undergraduate program based on subdiscipline specifications since 2008. The Anchoring Concepts Content Maps (or ACCM) have been published in four subdisciplines (general, organic, physical, and inorganic chemistry) with…

We present herein a module of pigment synthesis experiments that could be adapted and implemented in a variety of curricular settings. At the conclusion of each of the past two spring terms at our high school, we offered a 4 day short course on the chemical synthesis of pigments used in art. As part of the course, our students synthesized four…

In light of the COVID-19 pandemic situation, the separation of the primary colors of ink markers and food coloring was performed using a simplified column chromatography setup at home to accomplish the educational outcome of the course. The virtual class instruction, for the students enrolled in the "Organic Techniques Laboratory"…

There is a scarcity of studies that focus on how South African high school physical sciences teachers are grappling with chemical laboratory safety (CLS). This is despite the fact that the Curriculum and Assessment Policy Statements in the South African school system increased emphasis on laboratory activities in the physical sciences. Department…

Computer-assisted analysis of students' written responses to questions is becoming a possibility due to developments in technology. This could make such constructed response questions more feasible for use in large classrooms where multiple choice assessments are often considered a more practical option. In this study, we use a previously…

Extra virgin olive oil (EVOO) is a refined, highly valued, and relatively expensive food ingredient, typical of the Mediterranean area. Detection of EVOO that has been adulterated or counterfeited with the addition of variable quantities of low-quality and less-expensive vegetable oils is a challenging issue for analytical chemists. Analysis of…
