ChemEd X and the Journal of Chemical Education (JCE) are collaborating to offer a virtual conference like most have never seen before. It is not a webinar. You do not have to schedule specific hours to view a live presentation. I think of it as similar to a virtual book/journal club with the added benefit of having the author leading it. In this case, authors were selected from among those who have published recent articles, activities and research in JCE on the topic of student-centered instruction in chemistry. The theme of this inaugural conference is Chemistry Instruction for the Next Generation.
In this Pick, I will share a replacement simulation I found for studying Maxwell-Boltzmann Distribution Curves, as the previous online simulation I used was no longer working due to Java issues.
To assist in grading the lab results for this and other quantitative labs that we did, I created Excel spreadsheets where the students’ results could be entered. The spreadsheet then did all the required calculations and compared the students’ results to the theoretical value. This made grading the lab reports much quicker and more accurate, flagged incorrect student calculations, allowed a much more complete discussion of the lab results and permitted “what if” questions to be discussed.
I have had a variety of students with a broad range of academic abilities in my class at once. This hook doesn’t feel particularly deep until I stop and reflect for a moment on what that looks like.
Erica Jacobsen shares highlights from the April 2017 issue of the Journal of Chemical Education that are of special interest to high school chemistry teachers.
As many chemistry teachers know, grading lab reports can be a very time-consuming task. For me, the lab report that has required the most time to grade is a stoichiometry lab that I have been doing the past couple years. Though we do at least four “formal” lab reports each year, what makes this one different is that it involves a lot more calculations and subsequent results than any of our other labs. Regardless of how well they organized their report or wrote their conclusions, their results need to be checked for accuracy. This takes time. Even after eventually being able to generally eyeball their work, it still takes more time than I would like. So, this year I finally decided to sit down and generate a tool for me to expedite this process—the stoichiometry calculator.
Resources To Inform Teaching and Learning
The April 2017 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: green chemistry; environmental chemistry; using food chemistry to teach; 2016 Jame Bryant Award; development of important skills; chemical education research: assessment; advanced laboratories; from the archives: water quality.
On April 22, 2017, people all over the world will be coming together to stand up for science. The March for Science is a part of a global movement by scientists, science-enthusiasts, and evidence-based policy makers to celebrate the integral role science plays in all our lives. The March will serve to further several goals, I encourage you to read about them.
