What surprised you most about class last week? What do you think was the muddiest point in class last week? These two questions are part of an article that caught my eye in the November 2016 issue of the Journal of Chemical Education—Surprises in the Muddy Waters of High-Enrollment Courses.
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.
Science is cool. It allows us to step back and reason why things are the way they are. Most importantly it fuels us to keep questioning why. Asking why is an important aspect of learning, and is a huge part of the way classrooms run, on average a teacher will ask 300-400 questions just in a day (Vogler 2008)! However, what happens when a student does not have the correct answer to a question? Are they deemed wrong? Is it a misconception that we must fix?
Analytical Thinking, Analytical Action
The November 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: electrochemistry; researching how assessment aids learning; using technology to teach; environmental chemistry; hands-on, minds-on activities and demonstrations; geology-inspired chemistry.
Atomsmith works really well on Chromebooks and other platforms. Students can manipulate molecules, add water, do experiments, heat solutions and examine intermolecular forces all on the particulate level. Another nice feature is the "Experiment" section. There are a number of guided activities, usually never more than a page or two. I have found them to be great supplements for activities, experiments and demonstrations.
To squash any misconceptions, I would like to say first and foremost I am not a great cook. My husband graciously does most of the cooking in our house. However, as a chemist, I am fascinated by the complex reactions involved in everyday life. Pair this curiosity with the requirement to teach an elective, and the Chemistry of Cooking elective was born.
In July of 2016 we learned the names of the four new elements that were confirmed in January; Nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og). Although the newest superheavy elements complete the seventh period of the Periodic Table, curiosity has been reignited in our classrooms as students ask, what’s next?
Addition of a white solid to a green solution causes the solution to separate into some truly beautiful colors...
“What we Call Misconceptions May be Necessary Stepping Stones Toward Making Sense of the World” is an article identifying how misconceptions can be turned into sense-making exercises and classroom conversations to help students come to meaningful, and eventually “correct” views of scientific concepts.
