PBS has a wonderful new mini-series titled, "The Mystery of Matter: Search for the Elements". At the time of this post, the series is freely available to stream through your local PBS station.
What is your definition of the term “mole” in chemistry? Many articles have been written about the term and the confusion surrounding it. It was not considered an SI unit (with an IUPAC definition) until 1971. IUPAC is considering a change to the 1971 definition. There has been discussion about whether the SI definition of the mole as determined by IUPAC necessarily needs to be identical to the definition used by chemists and teachers. This article provides a short list of some recent JCE articles discussing the change and what it might mean for teachers while also considering some misconceptions related to the mole in chemistry class.
The August 2015 issue of the Journal of Chemical Education is now available online to subscribers. This issue includes articles on modeling instruction; Lewis dot structure model; molecular models; using models to teach crystal symmetry; introductory activities and labs; organic chemistry investigations and tools for engagement; enabling chemistry training for low vision or blind students; chemical education research in the literature; celebrating the work of Melanie Cooper; forensic chemistry articles from past issues.
How can our pedagogy broaden ideas of difference within and beyond the classroom to include social, cultural, linguistic, modal, and media differences, among others? Conference organizers welcome proposals that explore ways in which Writing Across the Curriculum can promote a dialogue on difference and inclusivity and encourage representatives of different populations to offer their multiple voices and perspectives on Writing Across the Curriculum today.
As school districts across the country approach the implementation of the Next Generation Science Standards, students will be required to develop models to illustrate what occurs at an atomic level as well as apply various mathematical representations in order to explain a science-based concept. However, what opportunities are we providing our students to allow them to explain what they know about a concept? Students should be provided with regular opportunities to develop and explain concepts, which in turn will allow teachers to formatively assess and address misconceptions.
What a mole-riffic time we are having here in Kennesaw, Georgia! Some highlights from my time here include:
~ The very appropriate cooling towels (Chill-its) we (ChemEd X) handed out to folks who stopped by our table, ran the Mole Run, or we saw between sessions. Several teachers have been diving in to research how they work. Chemistry in action!
NEACT is hosting a one day Summer Mini-Conference on Monday, August 10th at Clark University in Worcester, MA. Join us for a full day of exciting lectures, dramatic demonstrations and interesting workshops!
This book is not about chemistry, and it probably is the most "literary" book that I have written about in these pages. It is a beautiful story about the lives of a blind French girl, Marie-Laure, who escapes during the Nazi occupation of France with her father, the master locksmith of the Paris Museum of Natural History, to St.
Edmodo, Coursesites, Schoology…which digital learning platform is best for you? I’ve been searching for the right, free fit for me for the last three years. My journey has taken me from Edmodo to Coursesites to Schoology. I learned four valuable lessons about myself along the way that may help you make your own decision.
