A significant consequence of the COVID-19 pandemic in higher education has been the almost universal switch to a completely online modality of teaching. This work evaluates the efforts taken in teaching a freshmen general chemistry course at IISER Tirupati to students in India during the pandemic. Instructors used a multipronged approach to…

We describe a first-semester, integrated, introductory biology and chemistry course for undergraduates at Wellesley College in Wellesley, MA, USA. Our vision was to create a supportive learning community in which students could comfortably make connections between scientific disciplines as they learned necessary content for subsequent courses,…

A growing body of research suggests that student-centered teaching methods are associated with positive learning outcomes for undergraduate students. Yet, the extent of their use and factors leading to their adoption in fields, such as chemistry, continue to be under-explored. Utilizing survey data collected during 2015, we begin to fill this gap,…

This article focuses on the case study of the concept of covalent bonding for 10th grade pupils in France. On the basis of their conceptions and difficulties, didactical engineering has been established that should lead to an improvement in the understanding of this concept. After analyzing the pupils' difficulties, we reflected on the…

Inorganic Chemistry teaches students the concept that modifications to ligand structures, especially the donor properties, can have a drastic impact on the reactivity and stability of the metal complexes. Experiments described here reinforce this concept through the investigation of two tetradentate ligands derived from…

Background: A key aspect of STEM learning is the use of visual representations for problem solving. To successfully use visuals, students need to make sense of how they show concepts and to fluently perceive domain-relevant information in them. Adding support for sense making and perceptual fluency to problem-solving activities enhances students'…

In the era of universal and compulsory education, in which attention is paid to the ability to think scientifically, there should be no room for unscientific views. However, unscientific theories often appear in the media, and they find numerous supporters. Therefore, it was decided to investigate which of the common beliefs about the…

Chemistry teachers and students rarely consider the tension between daily life experiences and scientific ideas as a continuum where multiple modes of conceptualizing key ideas in chemistry coexist to function as a repertoire of views for making sense of phenomena. One of the central ideas in chemistry which teachers and students have multiple…

There are international concerns about decreasing rates of chemistry degree enrolment. This article seeks to understand students' reasons for not/choosing to pursue a chemistry degree, drawing on (i) open-ended survey responses from a sample of 506 students in England aged 21-22 who had studied advanced level ("A level") chemistry at age…

This research aims to draw a picture of chemistry lessons based on students' opinions in Hakkari, Turkey. The research design is a case study. An open-ended qualitative questionnaire consisting of 15 questions was used. The questionnaire was applied to 463 tenth- and eleventh-grade students studying at high schools in Hakkari. The data obtained…

Protocol-guided teaching is a student-centered instruction paradigm in which teachers compose learning protocols in advance to guide students through the entire learning process in an effort to foster in them the capacity for autonomous learning. Effective learning protocols can have a substantial impact on classroom outcomes. The purpose of this…

Gender inequality is strongly linked with poor performance in science and mathematics for female students in secondary schools owing to socio-economic and cultural issues as well as learning strategies. According to the Certificate of Secondary Education Examination results of 2021 in Tanzania, the failure rate for female students was higher than…

Summative lab assessments probe student mastery over concepts, but conventional ones often result in decreased student engagement and confidence. If conventional summative lab assessments are replaced by accessible gamified evaluations, such as online escape rooms, this leads to improved student engagement and confidence. In this work, we adapted…

We present a showcase of our experience with videos complementing analytical chemistry lectures to familiarize undergraduate students with instrumental element analysis. This includes a detailed account of how we planned, produced, and utilized a video to review the course content at the end of the semester. The analytical case study focused on…

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…
