Coding in Chemistry

coding

Computer coding has been getting a lot of attention with the Hour of Code movement and President Obama’s recent “Computer Science for All” initiative. Just like it is no longer solely the job of the English teacher to teach language and communication skills, it is no longer solely the job of the computer science teacher to teach programming skills.

Tell Me a Story

Just as our lives and various circumstances have a story, so do our laboratory experiences. Often the labs we do lack context but we expect students to buy in to the experiment without knowing the what, where, or why of the story. What makes this lab worth doing? What question(s) are we trying to answer? Why was someone exploring this in the first place?

Spring Fever, Stoichiometry and Specific Heat

Smore

From the looks of things, we are all in the same boat. Spring fever. I had two groups of students. Both are ending 3rd quarter, looking out a window at the first nice weather we have had in weeks. Most are already planning their spring break vacation and some have left early. Notice, not much talk about chemistry. The curriculum said it was time for stoichiometry for one group and specific heat for another. Just what the kids wanted to do (read with sarcasm).

Four Ways to Fight Spring Fever

How can I engage my students (and myself) for the last half of the semester? I read recently that the human attention span in 2015 is 8.25 seconds(link is external), which is down from 2000’s 12-second span. Currently, we are just beneath goldfish, who can attend to one thought for 9 seconds. I’m not sure of the methods of the research study, and I maintain a level of healthy skepticism. However, I admit my thoughts often spring from topic to topic like a bubble gum machine bouncy ball.

The Art of the Chemical Demonstration

One of my favorite things to talk about with my colleagues is the use of lecture demonstrations in teaching. There seems to be a push in my district to stop using chemicals whenever possible and get to computer simulations and video in place of wet chemistry. I don’t think they are thrilled with me since I can’t envision ever taking the chemistry out of chemistry.
