At this point, there doesn’t seem to be a bank of released NGSS assessment items that we can draw from to use in our own classes, especially for traditional Chemistry classes. This means, that we as teachers may need to write some of our own assessment prompts to use in our classes.
Erica Jacobsen shares highlights from the June 2019 issue of the Journal of Chemical Education of special interest to our ChemEd X community.
Like most concepts in chemistry, intermolecular forces takes a bit of imagination and critical thinking to fully comprehend and apply when explaining a variety of situations. Though demonstrating the presence of these forces in a simple and explicit manner can easily be done, I wanted to change how I introduced IMFs a bit this year by focusing on a more data-to-concepts approach.
In honor of the International Year of the Periodic Table: A familiarity with the chemistry of some of the elements more commonly encountered in everyday life is a valuable learning experience for all students. Sulfur is the fourth in this series of elements to be discussed as part of the Element of the Month program. #IYPT
My district recently provided a professional development session focused on utilizing three dimensional formative assessments in the classroom. The ideas I learned in the session as well an an activity for students to engage in formative assessment are outlined.
How many of you could recite, word for word, a definition you learned in school? When you first memorized the definition, you could state “inertia is a property of matter”, or “density is mass over volume.” However, you struggled to apply it to a new situation and maybe you were unsure of how to construct a model of what it meant.
My experience with the National Board Certification process was much like a Hero’s Journey plotline utilized in popular movies like Star Wars. Through my National Board Certification in Chemistry journey, I was able to navigate all the highs and lows to transform into a stronger teacher than I had ever thought possible.

Atomic theory is a common topic throughout any introductory chemistry course. It is likely that Rutherford’s gold foil experiment gets at least some attention in your course. I have used a simple activity that gives students an opportunity to replicate Rutherford’s experiment through an analogy experiment that may allow for easier conceptualization of the experiment itself and provide additional support for model development.
Like many members of the ChemEd X community, I am working with colleagues to teach and assess the Next Generation Science Standards in our high school’s general chemistry course. We are invested in engaging our students in Three-Dimensional Learning. This article aims to introduce readers to four of the high-impact shifts in mindset and practices we believe are helping our students learn to be better scientists.
