To give away my age a little bit, I remember writing and using note cards in high school. I hated it. I had (and still have) horrible handwriting, I could not keep them in order and cards from one class would invariably end up in another class.
As a physics teacher I allow my students to use an "equation card". This can be a note card or a piece of paper where the students can write equations and definitions. They can use this on test and quizzes. I try to stress to my students that I am more interested in how they solve the problem than their answer. As many of you are aware, many physics problems require multiple steps to solve, especially projectile motion problems.
I have tried many methods do help my students become proficient at solving projectile motion problems with varying degrees of success. This year however, I stumbled upon an idea while observing my students as they were taking notes, more specifically how they were taking notes: they were using their phones and taking pictures of the board!! What a concept!
So, I quickly came up with an idea. I used Google Docs and created "note cards" that had all the individual steps needed to solve a projectile motion problems. I then printed them on business cards and had the students arrange them in the correct order. Then, they were to take their phones out and take a picture! Welcome to the new face of note cards!!
I have embedded a little video I created using WeVideo that shows how the students completed this activity.
For those who are interested here is a folder with a completed problem as well as the cards: Projectile Motion Docs
