Abstract	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-school students around the world lack fundamental understanding of chemical bonding. In order to improve students' understanding of this concept, it was essential to propose a systemic treatment, namely, revising the scientific content, the pedagogical approach, and the assessment methods regarding this concept. Therefore, the main goal of this study was to build a conceptual framework that provides an advanced scientific and pedagogical foundation regarding the chemical bonding concept--one that will guide chemistry curriculum developers as well. A conceptual framework for a new teaching approach was constructed with lead-chemistry teachers, science (chemistry) educators, and research chemists. We suggest that chemical bonding should be taught based on elemental principles and by using the idea of a continuum of bond strengths. Our process includes the formulation of "learning goals" aligned with current scientific knowledge. Moreover, we suggest that constructing assessment tasks on carefully specified learning goals, which are described in terms of "learning performances," may enable educators to foster and examine much deeper levels of students' understanding.
