Consider helping the AAAS Project 2061 pilot their newly developed assessment tasks that measure students' ability to use the three dimensions outlined by the Next Generation Science Standards - science and engineering practices, crosscutting concepts, and disciplinary core ideas related to energy. Elementary, middle, and high school science teachers and college/university professors teaching in the U.S. that have students in 4th through 12th grade or undergraduate students and are willing to pilot these assessment tasks with their students are invited to register.
A solid grasp of proportional thinking is crucial to being able to solve all sorts of problems in chemistry as well as “real life” situations. While many students seem to intuitively understand that one mole is equal to 6.022 x 1023 particles when the analogy is drawn to a dozen eggs, for some, this sort of equality is a puzzling mystery.
I ran a multi-day poll on Twitter that was designed to be a fun way to determine the “best” element on the periodic table. I’m sharing about the poll here on ChemEdX in case others might want to try something similar in their classrooms. The poll was run tournament-style, fashioned after NCAA Basketball’s March Madness. The event was called #MarchMatterMadness. Just like basketball’s March Madness tournament, four different “regions” were set up, and each element was seeded into brackets according to atomic number.
he Biennial Conference on Chemical Education (BCCE) will be held at Notre Dame in South Bend, Indiana from July 29 through August 2, 2018. This is an excellent professional development opportunity for high school and college chemistry instructors.
Who doesn't need money for lab equipment, instructional aids or professional development? Do you have an idea for an outreach event that you cannot afford to to run? Apply for a Hach grant. There is no time to waste. The proposal is due April 16th, 2018.
The Biennial Conference on Chemical Education (BCCE) is providing an engaging afternoon program for K-8 teachers interested in physical science or chemistry concepts in their classrooms. This summer marks the 25th BCCE meeting and the first time the organizers have developed programming for the K-8 community. Registration is now open!
A greener procedure that you might consider to replace the traditional "formula of a hydrate lab" that has typically used copper II sulfate.
NGSS crosscutting concepts and core ideas are intended to be used as evidence to support explanations and arguments. I have found several lists of Chemistry core ideas online, but I don’t think I would give the ones I have seen to my students because they are either too long or written with language that I don’t think is suitable for novice learners of Chemistry. I have compiled a list of the crosscutting concepts and 12 core ideas for high school Chemistry that my students could use to support the explanations and arguments I will be asking them to write.
