The grade inflation is true, and even at top schools. <snip>
It is true that many students at my school have entered for decades with very low levels of skills. If these students received the grades that were the norm years ago, too many would have failed to be acceptable to their parents and the administration. The usual response is that we are not good teachers if we have many failing students. Thus we respond by raising the grades or making the conditions easier by making tests easier, or giving students more chances to pass, or more time to decide whether to withdraw without receiving a grade.
You have identified two problems here- one is the preparation of entering students, and the other is 'grade inflation'. These are very deep and important issues, and I don't claim to have a solution, but here's my perspective:
1) Student preparation. I agree with you completely. My students completely lack the mathematical background for algebra-based physics I. Often, the prerequisite math class was taken 1+ years prior and have been totally forgotten. My students can't tell me the formulas for the area of a circle, the solution for a quadratic equation, or which trig function (sine or cosine) is used to obtain the component of a vector.
I'm not singling out math prep- their lab reports are atrocious as well. There is evidence of poor organizational skills in nearly every homework assignment and test that I grade.
However- from speaking to colleagues (and from other threads on PF), it seems to me that this is a near-universal complaint (students not being prepared *regardless* of the course), and has been the case for at least 20 years. So this isn't a new problem. And while it is tempting to put the blame on the K-12 system, that doesn't solve the problem, it just shifts blame.
I've started toying with using some recitation periods (the class is a 2-lecture, 2-recitation, 1-lab period per week) to teach basic problem-solving skills. Instead of working through Physics problems, I have the students solve problems in their daily lives: making dinner, paying bills, managing a schedule, etc. The students seem to really like it, but I'm not convinced it's worthwhile yet.
2) grade inflation. Something that surprised me when I started "officially" teaching was the complete lack of information provided to me about *how* to grade. Think about it- the grade is the #1 concern of students, and yet teachers (me, anyway) are not given any guidance about assigning grades. Of course new teachers will be sympathetic to students, and figure it doesn't matter one way or another. Even now I have not had a single discussion about grade distributions with anyone- *anyone*- who is in a position to evaluate my teaching effectiveness.
This is a real issue I have been struggling with- what is required to earn an 'A' in my class? How do I objectively distinguish between an 'A' or a 'B' (or if you prefer, a score of 90% versus 89%)? Conversely, what does a student have to (not) do to earn a 'D' instead of an 'F'? I have students that show up at every class, actively participate in class, attend every recitation, regularly show up at my office hours, spend hours on homeworks, and still do poorly- what grade should they be assigned?
But again, grade inflation (or more generally, 'loosening of standards') has been going on for a long time- My previous institution *eliminated* grades about 15 years ago- medical school is now pass/fail only- and my dad complained bitterly about it for months. Of course, he also complained that today's students had it too easy- when he was in medical school not only was attendance compulsory, but so was wearing a shirt and tie.
Maybe we should be asking about the function of a college education: it's a box to be checked by some, a route to a better job for others, and we (the givers of parchment) should give students what they *need* to move on to the next phase of life (as opposed to what they *want*).
