This work aims to evaluate the evolution of chemical bonding concepts of high school students at public schools in southern Brazil. For this, we built the epistemological profile of each student who took part in a teaching-learning sequence (TLS) about this topic, based on the foundations of Bachelard's theory. Following the principles of the…

Teaching chemical bonding using the octet rule as an explanatory principle is problematic in many ways. The aim of this case study is to understand the learning and teaching of chemical bonding using a research-informed teaching model in which chemical bonding is introduced as an electrostatic phenomenon. The study posed two main questions: (i)…

An escape room uses a game-based active learning approach to develop students' critical thinking and problem-solving skills in an immersive environment. An escape room was developed to provide an innovative method to reinforce concepts in chemical bonding for a first-year general chemistry course. Because of the COVID-19 pandemic, it was…

The purpose of this research was to determine the heuristics used by pre-service science teachers in understanding the details of hydrogen bonding. The reasoning processes demonstrated were evaluated based on ten heuristic models suggested by Talanquer (2014). Phenomenographic assessment of the 30 participants indicated that all ten heuristics…

Personal stories serve learning and socioemotional functions in teaching. Instructors share personal stories with students to promote engagement, foster learning, and create a sense of community. Students may also share personal stories with each other for similar reasons. Thus, the current study explored how often, and why, students (N = 79)…

Assessment of student learning within a degree program is an important but challenging endeavor. One goal of a programmatic assessment is to systematically collect evidence for chemistry majors' knowledge and understanding and to use the results to improve curriculum and instruction. Recently, the chemistry department at the United States Naval…

An introduction to the noble gases and chemical bonding via Lewis theory and the octet rule are common inclusions in secondary school curricula. However, the usual approach may lead to misconceptions and difficulties when valence bond (VB) theory and valence shell electron pair repulsion (VSEPR) theory are taught at a later pre-university stage.…

Principals' efforts to support the implementation of interventions involve coordination among multiple actors in their social networks. However, less is known about how distinct features of these social networks are associated with principals' perceptions of the social validity of interventions. In this paper, we used Neal and Neal (Implement Sci…

Development of cognitive skills is critical for developing the right conceptual ideas in chemistry. Atomic structure, bonding, and associated properties are taught as parts of high school chemistry courses worldwide. The cumulative build-up of misconceptions about the periodic table is to blame for students' poor performance on atoms and…

The aim of this study was to examine how mentors provide social capital to Latinx adolescents in science education. Participants were drawn from a long-term, comprehensive science support program at a medical university in the Midwest. Using a case study approach, various stakeholders participated in one-on-one, in-depth qualitative interviews: 11…

Negative relationships among peers, such as bullying, are risk factors for children's life satisfaction (LS). This is due to their negative impact on youth development over time. LS refers to the evaluation people make of their lives and overall quality of life. Within the school context, there are several important dimensions to the development…

The growing popularity of flipped, blended, and online learning, combined with the need to support a student population with increasingly diverse backgrounds, has led to the development and use of online materials to support students' learning of chemistry outside of a face-to-face classroom. Chemistry simulations provide opportunities to make…

The integration of information and communication tools in education has been a common trend in the last decade which resulted in increased student engagement, motivation, and even achievement and learning. Despite these improvements, science teachers still report challenges with its use in science education. Several abstract topics in chemistry…

Students are often unsure of how to select the right study path at a higher educational institution. They either lack knowledge of a proposed study path or they do not manage to learn more before making their selection. Universities often apply various approaches, such as printed or online course curricula, to facilitate the selection process. Yet…

Helping international students create meaningful on-campus connections is a major part of higher education's internationalization efforts. By focusing on the efforts made by both international and domestic students to develop a sense of belonging through on-campus organizations like clubs and sports, we have the opportunity to consider their…
