This article systematically reviews the pedagogical approaches adopted in high school chemistry education with the aim of highlighting the most effective evidence-based instructional practices reported in the literature. For this, a meta-analysis of 35 pedagogical approaches is analyzed, and their effect sizes (Cohen's d) are compared in terms of…

The switch to online instruction during the COVID-19 pandemic forced educators to adapt hands-on environmental engineering experiments to a remote curriculum previously conducted in a laboratory using expensive analytical instruments (>$2000 per device). Here, we describe how we developed a low-cost (<$200) aerosol sensor platform as a…

Investigating the optical properties of various chemical compounds using UV-vis spectrophotometers is an essential part of education in chemistry. However, commercial spectrophotometers are usually treated as "magic black boxes", where the dominant majority of optical elements are hidden "under the hood". This often limits…

Marble, formed by the metamorphism of limestone, is commonly used in the construction industry and sculpting. The mineral in marble is either calcite [CaCO[subscript 3]] or dolomite [CaMg(CO[subscript 3])[subscript 2]] or sometimes both. The pure white Carrara marble from Italy was made a household name by Michelangelo, the famous sculptor of the…

The focus in teaching and research is shifting from a traditional perspective of information literacy (IL) as a specific set of general, mostly text-based skills to a more comprehensive understanding of the complex aspects that constitute IL as an ongoing, context-specific process. However, there is a need for further insight into the social and…

Sustainability transitions need professionals with specific skills and attitudes that students often do not develop in their regular chemistry education. To foster sustainability change-maker competencies, we suggest augmenting higher education curricula, e.g., chemical degree programs, with transdisciplinary challenge-based learning combined with…

Group work can engage students in active learning, yet students often resist working with peers in class. We investigated the impact of five minimally structured, easily implemented group work strategies used during weekly problem-based discussion sections in two introductory chemistry courses through student surveys and quiz score analyses.…

Educational escape rooms are immersive puzzle-based games that rely on teamwork skills in problem-solving, critical thinking, and communication. This paper describes the development of desert island themed escape rooms in a blended learning environment using physical and online puzzles that were hosted on Genially. The blended escape rooms were…

Relying on the National-Local Joint Engineering Laboratory and National Chemical Design Competition for college students, a multidimensional education mode presented here combines the advantages of problem-based learning (PBL) and "Conceive-Design-Implement-Operate" (CDIO) approaches, while also overcoming the restrictions of PBL and…

Problem-based learning (PBL) is an acclaimed educational concept for laboratory teaching in chemistry, which significantly affects learner motivation. A central aim of PBL is to overcome educational problems with "cook-book" laboratories. For example, when students receive experimental instructions and apply the instructions similar to…

The ability of students to perform quantitative analysis is a fundamental aspect of analytical chemistry courses and laboratories. In this laboratory experiment, students quantitatively analyze both liquid and solid samples through the use of internal standard calibration and ATR-FTIR spectroscopy. Using a problem-based approach to selecting their…

Service-learning methodology makes a connection between student classroom learning and the application of knowledge to solve community needs. The present study was carried out with the Universidad Autónoma de Occidente (Colombia) community by environmental engineering students enrolled in a Chemistry 2 course. The students helped the Universidad…

A classroom based Problem Based Learning (PBL) activity was adapted to run as a remote activity during the COVID-19 pandemic using an approach described as virtual Problem Based Learning (vPBL). vPBL is based on (i) identification of a suitable learning platform that supports collaborative working in a way that mimics the classroom based activity…

Student-centered teaching has become increasingly common in higher education as researchers have demonstrated its efficacy in recent decades. Herein, we hope to establish an efficient problem-based learning (PBL) method, which can help upper-division students learn organic chemistry content by combining teaching materials, experimental literature,…

The problem-based learning (PBL) methodology has been applied in a set of chemistry courses at the University of Barcelona to determine the main factors that are relevant to a satisfactory application of this educational approach in different contexts (from undergraduate to master subjects). The exceptional situation resulting from the COVID-19…
