This communication reports the curriculum changes and how they worked when an upper-level experimental physical chemistry course had to switch from face-to-face to online teaching within a matter of days. Although several of the learning goals of the laboratory-based course could still be met in the online environment, others required…

Benefits of metacognition and active learning on student performance are well understood; however, little is known about the effect of the "explicit teaching of metacognition" combined with active learning on student performance in chemistry courses. Using a quasi-experimental study design, we investigated: (1) differences in performance…

This study aims to compare the impact of the Dual Situated Learning Model (DSLM) and conventional instructions in improving High School Students' understanding of chemical equilibrium concepts and the prevention of possible misconceptions. The study utilized a quasi-pretest-posttest control and experimental group design with two classes of XI SMAN…

In many countries, the choice of a STEM career, especially in chemistry, is decreasing. A shortage of appropriately skilled workers can become a threat to any country's future achievements. Our research strives to understand behavioral trends and career choice factors related to personal and environmental themes. Building on the foundations of the…

The divide between theory and practice is an enduring challenge commonly attributed to disconnection in teacher knowledge between 'knowing what to do' (planning) and 'doing what you know' (enacting in class). We re-visited this divide from the new perspective of pedagogical content knowledge with the purpose of examining the ways in which…

The use of ICT in science education offers many opportunities to promote students' learning and experimenting comprehensively. Considering that, it is important not simply to replace traditional media, but to explicitly identify the added value of ICT tools for students and teachers. Especially alternative forms of documenting experiments,…

In the case of Chemistry subjects at the higher middle level, students tend to have a low performance in terms of academic exploration, either because of lack of motivation or lack of preparation in previous courses. In order to improve not only the academic performance of students in some topics of thermodynamics, but also the quality of…

Juniorstudy is a concept of the University of Rostock, which can be used by school students before starting their time at the University. Thus, it is an instrument of supporting the choice of study direction. Moreover, we have been able to show in our last cohort, that using Juniorstudy courses also helps to significantly enhance the knowledge…

Flow synthesis in microfluidic devices has been rapidly adapted in the pharmaceutical industry and in many research laboratories. Yet, the cost of commercial flow reactors is a major factor limiting the dissemination of this technology in the undergraduate curriculum. Here, we present a laboratory activity where students design and fabricate…

One of the topics that chemistry teachers have a great challenge introducing is chemical equilibrium. When being introduced to chemical equilibrium, many students have difficulties in understanding that some reactions do not go to completion, as this contrasts most of their supposed prior experiences in chemistry lessons. Students may also…

Limonite is the field term for a mixed assemblage of ferric oxyhydroxides, often containing nonferric silicate impurities. It is abundant on Earth's surface, possesses variable iron content, and is easily recognized by distinctive yellow and ochre hues. Limonite is a unique centerpiece for undergraduate chemistry laboratories because each sample…

Engineering students in control courses have been observed to lack an understanding of equilibrium and stability, both of which are crucial concepts in this discipline. The introduction of these concepts is generally based on the study of classical examples from Newtonian mechanics supplemented with a control system. Equilibrium and stability are…

A demonstration is described of electrophoretic separation of carmine and sunset yellow with a paper-based device. The channel in the paper device was fabricated by hand with a wax pen. Electrophoretic separation of carmine and sunset yellow was achieved within a few minutes by applying potential on the channel using a simple and inexpensive power…

A simple molecular dynamics experiment is described to demonstrate transport properties for the undergraduate physical chemistry laboratory. The AMBER package is used to monitor self-diffusion in "n"-hexane. Scripts (available in the Supporting Information) make the process considerably easier for students, allowing them to focus on the…

The rise in carbon dioxide (CO[subscript 2]) concentration in the Earth's atmosphere, and the associated strengthening of the greenhouse effect, requires the development of low carbon technologies. New carbon capture processes are being developed to remove CO[subscript 2] that would otherwise be emitted from industrial processes and fossil fuel…
