Chemistry is often regarded as a difficult subject, an observation which sometimes repels
learners from continuing with studies in chemistry. This paper seeks to bring together the …

Chemical bonding is one of the key and basic concepts in chemistry. The learning of many
of the concepts taught in chemistry, in both secondary schools as well as in the colleges, is …

Infusing engineering design projects in K-12 settings can promote interest and attract a wide
range of students to engineering careers. However, the current climate of high-stakes testing …

We describe efforts toward the development of a hypothetical learning progression (HLP) for
the growth of grade 7–14 students' models of the structure, behavior and properties of …

Secondary school, undergraduate, and graduate level learners' mental models of bonding in
ionic substances were explored using an interview protocol that involved the use of physical …

Because Lewis structures provide a direct connection between molecular structure and
properties, the ability to construct and use them is an integral component of many chemistry …

A thorough understanding of chemical bonding requires familiarity with the particulate
nature of matter. In this study, a two‐tier multiple‐choice diagnostic instrument consisting of …

Identifying students' misconceptions and learning difficulties and finding effective ways of
addressing them has been one of the major concerns in chemistry education. However, the …

Context-based learning approaches have been implemented in school science over the last
40 years as a way to enhance students' interest in, as well as learning outcomes from …

The traditional pedagogical approach for teaching chemical bonding is often overly
simplistic and not aligned with the most up‐to‐date scientific models. As a result, high …
