Research experience is becoming an increasingly crucial element of today's undergraduate science curriculum. In recent years, the establishment of the Course-Based Undergraduate Research Experience Network (CUREnet) has provided a framework for the development of courses aiming to cultivate students' proficiency in undergraduate research…

During the COVID-19 pandemic, many colleges switched to online or hybrid formats for both lecture and laboratory course delivery. While virtual experiments, that is, "dry lab" experiences, teach students chemical theory, it is essential for students in chemistry laboratories to participate in hands-on laboratory activities. These…

The tribal communities in South India, especially those in the Wayanad region in the proximity of Kerala state, have low literacy rates and occupy a socio-culturally marginalized status among various demographic clusters in India. The pedagogies employed through mainstream schooling do not appeal to the students in the tribal community, resulting…

Learning to write chemical formulas of compounds is a basic and indispensable part of understanding and studying chemistry. However, it is hard for students with visual impairment to assess and learn molecular arrangements and formulas. For the convenience of such students with special needs, it is necessary to come up with easy, comprehensive,…

Persons excluded due to ethnicity or race (PEERs) leave STEM at disproportionate rates; therefore, efforts to engage undergraduate PEERs are critical to creating a diverse STEM workforce. Through a Howard Hughes Medical Institute funded Inclusive Excellence grant (HHMI-IE), the REALISE (REALizing Inclusive Science Excellence) program was developed…

Chemistry experiments are challenging for people with vision impairment (VI) as results often rely on visual observations such as a color change. This puts pupils with VI at a disadvantage both in their scientific learning and in their development of broader life skills. In this paper, we describe a simple and low-cost experiment on the adsorption…

In this study based on mixed-methods design, we aimed to examine to what extent the participants underwent pedagogical transformation and developed topic-specific pedagogical content knowledge (PCK) for planning to teach acid-base equilibrium. Training for the acquisition of pedagogical transformation competence to develop topic-specific PCK was…

At the molecular level, chemical processes involve the rearrangement of atoms in space and time. Students often struggle with visualizing the 3D spatial characteristics of molecules and transition states, as well as recognizing the dynamic nature of chemistry. Both visual spatial skills and representational competence should be explicitly trained…

A rudimentary level of scientific literacy is necessary in the general public. At the undergraduate level, this literacy can be achieved through general education courses offered in areas of natural sciences. Over the past several years, practical courses have been developed to make the teaching of chemistry concepts in the laboratory more…

Through an initial documentary analysis of the flipped classroom in the context of a pandemic and of the new pedagogical models based on active methodologies or pedagogies and cooperative learning, the experience presented below is part of an innovation project based on the design of cooperative activities focused on students to enhance their…

This study aims to examine the effects of argumentation-supported problem-based learning (AS-PBL) carried out in the Chemistry-II laboratory course on the conceptual understanding of prospective science teachers about "Chemical equilibrium and Le-Chatelier's principle". The prospective teachers' answers were analyzed using content…

Wildland fires have become a regular aspect of life for people living in the western United States. Wildfire smoke is now impacting air quality across the United States. Unprecedented wildfires have swept through Australia, Russia, and Portugal in the last few years. Like other natural disasters, wildland fires can have a devastating impact on…

A method is adapted for calculating two measures of entropy for gaze transitions to summarize and statistically compare eye-tracking data. A review of related eye-tracking studies sets the context for this approach. We argue that entropy analysis captures rich data that allows for robust statistical comparisons and can be used for more subtle…

This study aimed to uncover the ontological orientations of educators' sense of the atom of Kotebe Metropolitan University (KMU), Ethiopia. Thus, an interpretative case study design was employed, with the analytic approach of grounded theory, due to the importance of atomic ontology as a case and the need for an in-depth analysis of their thinking…

This study shows how students can learn about green and sustainable chemistry by using the knowledge perspective of a local indigenous culture as a starting point. This learning approach encourages students to learn chemistry by connecting culture with learning about green chemistry. The cultural context selects the use of a phytochemical agent…
