Wordle.net tag cloud for interesting topics covered in Midterm 2, generated by responses from Physics 205B students at Cuesta College, San Luis Obispo, CA (www.wordle.net/show/wrdl/5299046/Untitled).

Students have a weekly online reading assignment (hosted by SurveyMonkey.com), where they answer questions based on reading their textbook, material covered in previous lectures, opinion questions, and/or asking (anonymous) questions or making (anonymous) comments. Full credit is given for completing the online reading assignment before next week's lecture, regardless if whether their answers are correct/incorrect. Selected results/questions/comments are addressed by the instructor at the start of the following lecture.

List at least three words describing interesting subjects covered in class (up through this midterm). (Graded for completion.)

Describe your most interesting subject, and briefly explain why this subject interested you. (Graded for completion.)

The following are all of the student responses to this question, verbatim and unedited.

"I really liked learning about the right hand rules. They helped make things make sense and also helped me see what was going on with the problems."

"circuits were the most interesting because that was what I knew the least about"

"I enjoyed household electricity"

"magnetic fields being used to create generators and flux change. I like this because finding ways to utilize these changes which occur all around us, including the earth speeding along its path around the sun, and the magnetic field of the earth would be a fun challenge"

"induced current"

"Magnetic field. It was cool to how magnetic field, force, and current/velocity are related like in RHR1. It was also interesting to learn about the field model and how magnetic field acts with dipole magnets."

"Magnetic field"

"Magnetic Forces because of Star Wars!"

"resistance... light bulbs man"

"Magnetism because people still do not have a full understanding of it and possibly never will."

"Magnets"

"Magnetic Field"

"i like working with the magnetic fields and finding current and things like that. it just comes easier to me than the other subjects"

"That just by moving, a magnet can create electricity"

"Circuit analysis is my favorite part of this midterm. I like electronics and enjoy getting a look at how they work."

"circuits"

"Magnetic field lines because I never knew how they worked!!"

"The properties of magnets, because of their ability to induce current without contact"

"Magnetic field , the different scenarios it can create while having different variables"

"Magnetic fields, I really like the practical use if the right hand rules and Shakira hand rule."

"The magnetism stuff was cool because its fun to play with magnets"

"Induced Current because it has a wide range of applications, and is commonly used but not common knowledge."

"I thought magnetism was most interesting."

"Resistors and capacitors, i thought this was interesting because it applies to my everyday life."

"not much really"

"i thought the right hands rules were interesting and those make the most sense to me out of any of the other subjects."

"i love the RHRs they are easy to understanding the concept of directions and forces exerted.."
