Breaking the curve - Why a straight-scale is appropriate in engineering courses

Several points related to curved grading scales based upon statistical assumptions are discussed. ABET accreditation requires that the students should be well versed in communication and teamwork skills when they graduate. A curved grading scale inherently sets up competition between classmates because any aid they give to another student may raise the class average, making it harder for them to receive a high grade. This sense of competition may prevent students from forming true collaborations on their team projects and may prevent them from learning how to effectively communicate. It is suggested that all engineering courses should be taught on straight scales.
