Developing PCK requires a certain level of subject matter knowledge, and teachers have a different understanding of subject matter than a person who specializes in that same field. A chemistry teacher and a ‘practicing’ chemist both have subject matter knowledge in chemistry; however, the knowledge is applied differently.
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.
Supporting the Growth and Impact of Chemical Education
The March 2019 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: nanochemistry; supporting the growth and impact of chemical education research; using technology to enhance student experience and understanding; promoting student engagement; teaching with models; exploring kinetics; experimenting with innovative labs.
I am sharing a hack I use in my standards based grading (SBG) classroom to help things run more smoothly.
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.
Let me share some tips I learned reading the Advanced Placement Chemistry Exam in Salt Lake City, Utah.
This strategy has been very helpful in establishing relevance to topics taught and in making connections between topics taught within a unit. It also provides a way for students to ask questions and make written explanations of phenomena, which are “Science and Engineering Practices” of NGSS.
