Houston’s KHOU reports that at Lonestar College students enrolled in an introduction to chemistry section were taught instead an advanced chemistry course.
Apparently the mix-up was not discovered until almost the end of the semester, at which point almost every student in the course had a failing grade. The news report featured an student who had maintained an A average until she enrolled in this course. She observed that no matter how hard she studied for this course, she could not seem to score above a 40 on the exams.
After finally realizing that she had been teaching the wrong course for essentially the entire semester, the instructor applied a significant curve to the students’ grades. For instance, the student with an A average who could not manage an exam score above a 40 received a B as her final grade for the course.
I am assuming that all of the students who received final grades of C or above have now successfully met the prerequisite for the course that they have just completed and will now be able to re-take.
