Whаt fаctоr is NOT required tо mаintain Hardy-Weinberg equilibrium?
I hаve been using little mini-quizzes fоr severаl yeаrs nоw.Priоr to this, I had either weekly or biweekly (every other week) quizzes that covered more material and were worth more points. What happened in those cases was that many students would just skip the chapters altogether, take the quizzes blind, and then fail them (and the course) because they weren't learning anything.I realize that many students view the class with a "let me just complete the assignments without doing the reading and see what happens" attitude, so the mini quizzes are my attempt to a) help make the quizzes less scary since they're worth a few points each b) get the students who want to speed through the class to slow down and actually read the material so that they don't failThe problem is that it's increasingly apparent that some students are still not pacing themselves. Folks get confused because they're taking all of the quizzes at the same time on Sunday night, not one a day throughout the week (which is how they would learn best). So I am left with a dilemma, and that's what I'd like your feedback on in this question: Please share your opinion about the way the class organizes the quizzes (1 paragraph):Should the class keep the mini quizzes as they are, hoping that students will read a chapter and take the quiz immediately after (as is intended) throughout the week? Should the class go farther and hide each chapter until the previous quiz is taken? This would help some people stay on top of the work since they wouldn't even have access the material before taking the quiz. This would also inevitably doom other students who would never get access to the material, or who would still wait until Sunday and fail anyway.Should the class go back to just one larger weekly quiz (which is a little scarier for some students) and perhaps see even more students try to take the quiz without even reading the chapters?Please explain your thoughts on these suggestions and offer any others that you might have.
