I'm a bioengineering student at Rice University. For the duration of my academic career there's always been one thing that's bugged me above all else. Watching a student fail to understand something and a teacher being unable to convey it to that student. I would often find myself offering to help, after either the student or teacher had given up on the question. I found that frequently the problem wasn't in the difficulty in the material, but in the method of instruction. Some people just have a different way of looking at things and might need a more unconventional explanation. I apply this line of reasoning throughout my life, both in my engineering work and while working with friends trying to help each other understand difficult concepts. Sometimes all it takes is a different approach.
