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.
JCE ChemEd Xchange provides a place for sharing information and opinions. Currently, articles, blogs and reading lists from ChemEd X contributors are listed below. We plan to include other items that the community wishes to share through their contributions to ChemEd X.
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.
The James Bryant Conant Award was established in 1965 and has had several sponsors. The award is intended to recognize, encourage, and inspire outstanding teachers of high school chemistry. It is fitting that the Journal of Chemical Education and ChemEd X have established an endowment that will permanently fund the award. I think it is even more fitting that the 2017 Awardee, Laura Slocum, has a history with JCE as a precollege assistant editor from 2007 – 2011.
Each week I decided to put on paper, or in a blog, one concrete action that I could take that I was pretty sure would help at least one student. After almost three years and close to a hundred entries, the entries were separated into categories by multiple people. The result was pretty clear....my biggest struggles were with assessment.
The answer may be in the anecdotal evidence. The conversations between students were mini debates. “Are you sure this is correct?” “How do you know?” “What about this other data?” “Should we label that number?” “What about the energy of the particles during a phase change?” And on, and on, and on….They were having discussions between themselves that I would not have been able to elicit as a teacher.
