On-line Chemistry Courses - Maybe?

Want to heat up a department meeting? Just propose that all courses have an on-line option and watch as some colleagues have strong opinions about it- be it on one side or the other. What overlooked component can be distilled from a normal in-person course into an online that could have a significant impact? Perhaps the face-to-face “live” interaction.

Technology Considerations for the Chemistry Classroom

Technological Pedagogical Content Knowledge (TPCK) can be the vehicle by which teachers decide if and how a technological application can be incorporated into their classrooms. TPCK more recently coined as TPACK technology, pedagogy and content knowledge incorporates technology into Lee Shulman’s pedagogical content knowledge (PCK) construct. PCK is the means by which a teacher takes his/her content knowledge and transforms it into content knowledge for his/her students.

Building a Blended Culture in a Secondary Science Classroom

During my first year of teaching (in Indianapolis, IN), I was inspired by some research I had read as well as some other teachers in the Indy area who were flipping their classes. I was at a small parochial school where parental and administrative support for technology inclusion was present. My principal outfitted me with the tools I needed to “flip” my classes and record tutorial videos. Things went pretty well. It was a learning curve for many but I also had good feedback from students and parents.

How do you teach resonance?

During our review since last week, resonance was labeled as one of the most tricky concepts (along with electron pushing in my opinion), despite lots of practice and instruction. My teaching sequence consists of defining and providing examples of conjugation (after learning about hybridization), delocalized electrons, and finally pushing electrons if conjugation exists. I remember from teaching at the college level that resonance was also a tricky topic for many undergraduates.

 

Colligative Properties in Real Life

This year in the midwest United States, winter has been a fickle friend. I haven’t seen the same amount of snow or ice as in recent years, but I still made sure I was prepared for it at our home. I went to my local big box hardware store in December and contemplated buying rock salt (NaCl), and NaCl/calcium chloride mixture, or just calcium chloride. Growing up my dad had switched entirely to calcium chloride because it was less damaging to the brick pavers leading to our porch and backyard. In fact, calcium chloride is generally much safer toward plants and soil than NaCl. Even though calcium chloride is much more expensive than rock salt (it was about twice the cost for 10 pounds more), that what’s I chose. Why?

Blended Learning Pilot: #1

Last year, I researched and practiced what I thought to be "flipping the classroom". But, now that I am taking part in a district-wide "High School Blended Learning Pilot", I can say that I was attempting blended learning early in my teaching career. You see, the flipped classroom is really a small subtype of blended learning. So, the goal of this post is to define blended learning and share what my professional development has in store for me during this academic year.

Vocabulary Instruction

Late last school year at a staff meeting, teachers were informed that we were going to be coached and encouraged to introduce more vocabulary instruction to
