Trigonometry: Teaching concepts "out of order" and contextualizing content
A prerequisite to physics is MAT182. Students need to know law of sine/cosine, and vector concepts from trig to be successful in physics. In the past, I would spend a lot of time classify triangles (SSS, ASA, etc) to help students know which "law" to use, and this was done at the end of the semester. I did not spend time using law of sine/cosine with vector applications . Students typically scored a low B on law of sine/cosine problems. In F17, I taught the "laws" and incorporated vectors in week 4 to show students real life applications.
