Teachers should approach their classes not as task masters ,but as caring mentors. As a teacher of technical subjects (math, stat)I keep assuring the students that by the third part of the semester the material will come together and they will see the whole .I do not penalize the students for faulty work while they are learning. This approach is quite effective in reducing plagiarism.

model,manager and motivator. all is fine and necessary. but the ability to package the material and present it is the most important skill.
