Most chemistry teachers I know do flame tests with their students. It ties in well with many topics, is colorful and the kids enjoy seeing the colors and burning stuff. There are many applications. For years I always mentioned that astronomers use the idea of the flame test. They simply look at stars and examine the spectra from the light of these stars. They then match the spectra with the elements and then they can see and infer what elements are millions of light years away. I always mentioned this but never was able to demonstrate it.

There has been considerable discussion lately of standard based teaching. Essentially, a teacher has a set of standards and they teach to these standards. The idea is that instead of saying "Hey, you got a C on this test, time to move on..." a teacher would say "This is the standard...you can exceed it, meet it or you can approach it...the goal is to meet or exceed the standard and if you do not, keep trying." Here is an example...we were covering gas laws in my class. I asked seven questions about conceptual ideas concerning gas laws.

Join me, along with co-presenter Rachel Murillo, on Thursday, September 15, 2016, 6:30 p.m. Eastern. Rachel brings her background in forensic anthropology to the webinar, along with her current work teaching high school forensic science. We’ll share forensics resources useful for National Chemistry Week, for integrating into classroom curriculum, and for informal science sharing. Anyone who wants to connect science to this high-interest, real world topic will find ready-to-use demonstrations, lab investigations, videos, background information, and more.

ActiveGrade has been a favorite among practitioners of Standards-Based Assessment.  It's intuitive interface and elegant data displays helped teachers, students, and parents have meaningful conversations about student progress and assessment. For as little as $60.00 a year, teachers could tap into this powerful intructional tool.

What is the best way for students to visualize compounds? From the traditional physical ball and stick models to the various online simulations the objective for all of these tools is to provide one with a visual for the different structures and patterns. This summer while facilitating a workshop, the participants and I discussed this question and while reviewing various representations we came across MolView.

John Hattie is a guy who spent twenty five years doing over 50000 meta analysis studies on about 80 million students and wrote a book called “Visible Learning”. He has also done a number of TED talks. Essentially, he asks the question, “What affects students learning?” and clearly as well as simply defines what an “effect” is. He told the story of a researcher who spent years recording classroom interactions from the perspective of the student and the teacher. The researcher was surprised to learn that about seventy percent of learning was not visible to the teacher. So..even the best teachers with the best data only get about thirty percent of the picture. Next came the book, Visible Learning for Teachers and the website “Visible Learning Plus”.

Are you entering your first year of teaching? Or did you just finish your first year of teaching? If so, and you live in the United States, consider applying for a fellowship from the Knowles Science Teaching Foundation (KSTF).
