The Biennial Conference on Chemical Education (BCCE) will be held at the University of Northern Colorado in Greeley, CO from July 31 through August 4, 2016. This is an excellent professional development opportunity for high school and college chemistry instructors. You still have time to submit an abstract to present. Presentations are generally 20 minutes in length.
In my high school chemistry class, a unit we cover is that of atomic structure. In particular, given an elements symbol, mass number, atomic number, and charge, the objective would be for the student to determine the atoms number of protons, neutrons, and electrons. I have several apps/program suggestions that can be useful for this purpose.
I’m a first year AP chemistry teacher. My emotions swing from fear of inadequacy to confusion in pacing to acute awareness of the number of years since college chemistry to desperation in grading 55 lab notebooks to exhaustion with inexperience. Honest truth: I'm studying. I'm studying a lot. Despite 14 years of chemistry teaching experience, I feel blindfolded again.
Most chemistry teachers somehow teach Lewis dot structures. These structures are the foundation for VSEPR theory, three dimensional models and ultimately how the structure allows us to predict what happens on a large scale. Here is the crazy part...there are a number of different "rules" that really do not make a whole lot of sense. Do a quick search...everyone has there own rules.
In this blog post, I’ve asked Natalie about her journey as a woman of color along the path toward a future in a STEM field. I can’t begin to understand her perspective, so I’ve asked her to lend her voice to this issue. I believe it is important that we, as educators, take some time to reflect on what she has to say. Sometimes, the things we don’t say are resonating just as loudly as the things we do.
Technology is a word that can generate a great deal of debate in a chemistry classroom. I got into an interesting conversation with a teacher who is new to my school this year as she was moving into her classroom next to mine. That room had only had one occupant since the school opened 25 years ago and I have been the only teacher in my classroom since the school opened.
I hate to sound like a broken record but I used two activities from Grand Valley State Target Inquiry Program (link is external) that worked amazingly well and had a great "flow". Chad Bridle wrote two inquiry activities that dovetail together. The first is "Changes You Can Believe In". Students are presented first with nine cards that are particulate drawings of changes that occur in matter.
Over the last few weeks, I have been working with a middle school physical science teacher, Morgan, to develop a PBL experience for her students as they learn the basics of the atom, periodic trends, and bonding types. She is a first year teacher and has been so fun to work with. It has been really eye opening to work with her - in a good way. As I work with another teacher, I have realized that I have forgotten how big of a task it is to create ALL OF THE PIECES of these experiences for students (and let’s be real, we are a bit crazy to create this during the school year). My goal is always to be real with my writing and experiences, and here is something a bit more real for you all. In this post, I am sharing what it is like to develop a project from both my perspective and, most importantly, from Morgan’s. Think of it as a view from the trenches.
