From The Chronicle of Higher Education:
Different students learn in different ways—we know that. Students know that too.
A precalculus student I talked to on a recent afternoon failed the class last fall and was on her way to failing it again this spring. Sadly, she will probably fail the class in the fall, too. Despite all the class aids (and there were many), she had not reacted to her consistently low exam scores until I spoke to her after class.
