Does the math teacher make the difference?

[MathHeroine]

I was at my school's tutoring center and heard these two guys agreeing on how math teachers make a huge difference on how well you're going to do in whatever math class you're taking. Do you agree or disagree?

 

[genericusrnme]

People who only study from their classes will certainly be affected by the teacher. If the teacher just presents formulas and tells you what to do with them then you won't understand anything and you'll do poorly, if they derive formulas, explain their motivation and explain why they're useful then the you will understand and you'll do well, assuming you put in some effort on your side.

If you're using a textbook then, again, it's based on how well the author presents the material.

No one is born with some supernatural ability to do maths, maths is a man made construct, just like guitar, that you need to practice and learn about - good teachers and good textbooks just makes that job easier.

 

[mal4mac]

If you have a bad teacher, who is not teaching from a set textbook, then that can make a huge difference! It's even worse if the teacher seems like a good teacher, but they are teaching from the wrong textbook... (my only explanation for one Math exam I didn't do well in... always check the syllabus and past exam papers...)

 

[HallsofIvy]

Actual studies have shown that the quality of the teacher, while is certainly has an effect, is not as important as we might think. If a teacher is not very good, the good students will spend more time reading and working on their own which is always a valuable skill. Poor students will do slightly worse under a poor teacher than a good but not a great deal.

 

[Jorriss]

For the majority of my instructors, no, not a huge difference. However, I have had a few exceptions where the teachings are just phenomenal and make me 1) understand the material on a deeper level and 2) inspire me to study more! That makes a very big difference.

 

[member 392791]

personally I will take any teacher no matter what their ratemyprofessor.com ratings say UNLESS they are just grouchy or rude or whatever, as long as I can talk to the professor and they are nice people, I usually ignore their teaching ability

 

[chiro]

Hey MathHeroine and welcome to the forums.

My opinion is that everyone you're involved with makes a difference.

Also it doesn't have to strictly a 'physical involvement': if you read textbooks, blogs, forums etc then that will be part of your influence.

Everything you come in contact with, your past experiences, your upbringing in addition to your teachers will help.

For example you might have a great teacher but if you have a bad attitude and throw away all the advice and assistance, then yeah you won't necessarily make use of having a good teacher.

But then again you could be very persistant, have a great attitude, a lot of initiative and still go very very well without having a decent teacher.

One has to consider the whole spectrum and not just an isolated facet of it.

 

[Nabeshin]

Style is very important to me for mathematics professors. As a physicist approaching mathematics, I like to reason intuitively and try to feel a problem out before jumping into abstract proofs. Consequently, I do well in classes with professors who act similarly, and rather struggle otherwise. This is just one example, but I like it because it concretely shows the difference in teaching styles.

 

[Moonbear]

Actuall studies have shown that the quality of the teacher, while is certainly has an effect, is not as important as we might think. If a teacher is not very good, the good students will spend more time reading and working on their own which is always a valuable skill. Poor students will do slightly worse under a poor teacher than a good but not a great deal.

It depends on how you define a good teacher and what measure of performance is used. I read a great study from a military academy, where they could eliminate things like selection biases by randomizing students to instructors, and eliminated variation in course sequencing because all of the students had to take the same courses in the same order. They followed them longitudinally. The instructors perceived (by student evaluations) as better were the ones that prepared them better for the common exam all sections took for a course. The ones who were perceived as worse or harder teachers generally had students who didn't perform as well on the common exam. However, when the students were followed to the next year's courses, those with the harder first year instructors performed better at recalling principles from the first course needed to succeed in the second course. They had worked harder to learn in first year rather than being taught to the test or just memorizing enough to pass the test, so retained what they learned. So, the difference in teaching and student performance depended on whether it was short-term test scores or long-term retention of the material that was measured.

The study was actually intended to measure the validity of student evaluations of instruction. I can't remember where I saw it published to cite it though.

 

[alienprophecy]

As a student, I would have to say that the math teacher does make a difference, but that's not an excuse to make an excuse. I have had a couple of good teachers, and a couple of bad ones. The worst experience was with a teacher that was "faking it."

I realized that he was faking it when I went online to watch the MIT lectures, and recognized my teacher's lecture as having been lifted from it almost verbatim. I recognize that this happens, as subjects such as physics and math tend to recycle a lot of problems over the years...but this was uncanny: my teacher's English wasn't all that good, and when asked for clarification he didn't seem to understand the meaning of some of his own words.

This is how I know I have a bad teacher: if I read ahead and understand, then go to class and become confused, the teacher sucks.

 

[bpatrick]

not that this has to due with the quality of teaching ability, but this story is more about the general quality of the professor and how little he cared about the students he was teaching:

I have always been a self motivating learner. when I took ODEs freshman year of college, the prof said we didn't have to come to class, so I didn't. I came for the review sessions before the exams, then got As on the exams and went on with my life, no worries, got an A in the course.

sophomore year came and I enrolled in (sophomore level) classical mechanics. the prof started the lecture right away after handing out the syllabus (and not talking about it at all). The syllabus stated that attendance was optional and grades will be determined: 30% exam 1, 30% exam 2, 40% final. I did the same thing I did for my ODE class, went to review sessions, got an A, B+, and A- on the three exams ... so I should have been looking at probably an A- for the course right?

I ended up getting an F on my transcript and thought it was some mistake, when I got back to school in January, I talked to him, and the chair of the physics department. Evidently the first day of class, the prof mistakenly distributed the syllabus from when he taught it two fall semesters before. I had noticed the date on the top of the paper (because I frequently referenced it throughout the semester as I read the proper sections in the book) but i thought the prof was just too lazy or didn't notice he forgot to change the date when he reused the syllabus.

The man never informed me that he had changed the syllabus! ... now how bloody hard is it to send an email with the change? or when you administer the first exam to say, "hey, [bpatrick], i haven't seen you in class, don't you care about your participation grade? ... even with straight As on the exams you'll only get a D given the weight of attendance and homework!", but not a single word for the professor the entire semester, hell, I even went to his office hours once and asked for advice on solving a problem I was working on. All he said was, "we did something like this in class last Wednesday, why don't you come to class or get notes from another student."

I never ended up getting the grade changed (the university gave an option to retake up to 2 courses that you received a C- or lower in), but by the next fall, I had already completed my minor in physics and the same prof was teaching the course again. I had no desire to be in the same room with that man for an entire semester wasting my time on stuff I already could do, and needed to be taking another course that fall in my major that was offered at the same time.

overall, i say that's a pretty awful teacher and just an ahole in general. Until then, I was thinking about double majoring in physics and possibly going to grad school in physics, but when that happened, I ended up focusing on my music instead. It's amazing what a single teacher can do, haha.

I find it really difficult to imagine they wouldn't consider a grade change, or an incomplete, or something given the syllabus didn't mention participation. That's garbagety =/

 

[bpatrick]

I find it really difficult to imagine they wouldn't consider a grade change, or an incomplete, or something given the syllabus didn't mention participation. That's garbagety =/

the department chair did consider it, but it came down to a few main things:
- the prof i had was the assistant chair (didn't mention that) so he had some clout
- I didn't go to a single class, so the department chair didn't have much sympathy for me
- I wasn't a physics major (pretty sure that would have made a difference although it shouldn't)
- I had an opportunity (via university policy) to retake it and replace the grade if I chose to do that

 

[DrummingAtom]

I've had the experience that some math teachers make things harder than it seems. My calc 1 and 2 professors were incredible teaching to my style which is visual and intuitive. I need a simple concept and picture then I can start getting more abstract. My diffy Q teacher didn't do this at all and it was a cannonball into the deep end with abstraction and I really struggled at first because I had to find other means of learning. I have a friend that's the complete of my style of learning. He always says a picture gives him nothing, he needs the logical abstract reasoning and then learns it incredibly fast. The teacher depends on what style of learning is best for which specific student.

 

[DrummingAtom]

The study was actually intended to measure the validity of student evaluations of instruction. I can't remember where I saw it published to cite it though.

Hey Moonbear, if you do find that study can you post it? I would love to read it.

 

[Sankaku]

The ones who were perceived as worse or harder teachers...

This is a subtle point. Not everyone rates teachers on the same criteria.

Yes, many students simply rate based on how hard they are forced to work. However, I suspect better students will rate a professor on how well they teach and how fairly they test (note that fair does not equal easy).

I am sure your study is correct in that discomfort at working hard is not a good indicator of class quality. However, a professor who is poor at teaching, or who has unfair expectations, can genuinely ruin a good student's interest in a subject.

 

[adiphysics]

A good teacher is one who can clear all your doubts and has the ability to convince you that what he is telling is right.If he does not know something he should clearly say that he does not ,suggest some book to refer or postpone it for later rather than misguiding the student.

When it comes to ruining interest,that is what I suffered in chemistry in grade 9,10 at school.My teacher rather than explaining anything used to dictate notes and ask questions to humiliate students rather than test them.She did not even entertain a doubt ,just looked to complete the syllabus.Just opposite happened in physics in which I am deeply interested now.A teacher can definitely affect your interest in any subject.

Yup. Giant ahole because YOU decided you were too good for lecture, and this professor didn't kiss your *** to get you to come to lecture. That's your responsibility brosef, not his.

 

[mathwonk]

I do believe the teacher can make a difference, but the same teacher will not make the same difference to every student. The thing to seek is the good relationship, or the good match between student and teacher, since not every student learns in the same way, nor seeks the same outcome.

Thus I found the study mentioned by Moonbear completely in line with what I have observed over my career, When I read teacher evaluations of professors in order to give awards or promotions, I observed that overwhelmingly, the highest evaluations went to the professors who gave the highest grades. Those professors apparently had the happiest students. In some cases those professors were also excellent at explaining the material, but they tested that material in a far less challenging way than others did. In those cases their grades did not discriminate at all between merely average good students and really excellent ones as essentially everyone got an A.

There were also exceptions however. There were some professors who were both challenging and excellent and this was noted by the students who said the professor's class was not easy but they felt the professor went out of her/his way to give the students every chance to learn as much as possible. When awarding prizes for teaching I looked for these latter instances, but they were only a small subset of the teachers.

Indeed since promotions and raises and hiring depend in many cases at least partly on these evaluations, most teachers have apparently learned to placate the students with easier classes, and not to make the grade depend on really excellent performance.

So as Moonbear made clear, the meaning of the term "good teacher" depends on what the evaluator is looking for: clear explanations, deep insight, more advanced versions of material than found in books, higher grades than average or than deserved, willingness to overlook lazy performance or absences, concern for the student's needs and feelings,...

Years ago I wrote an essay "On teaching" that was published by request of one of my students then in the math ed department. It is #8 under class notes on this page:

http://www.math.uga.edu/~roy/

In it I refer to the passage in scripture where Jesus rebukes a follower for calling him "good teacher", responding none is actually good except God.

 

[daveyinaz]

Actually, bpatrick is not the ahole in this scenario but rather the institution he attended is and possibly you for not understanding that the syllabus acts as a contract between the professor and the student administratively. Since he was given a false set of guidelines to follow, he should not have been faulted for doing what he was fully within his right to do under those specific terms.

The professor updated the syllabus saying so. It's common knowledge that syllabuses are subject to change during the first few weeks (My stats syllabus reached it's final version in week 4). If he's going to prance about like he's better than the institution, it'd have been wise to show up to class every once in a while. It was not the professors job to reach out to one of his many, many students (especially one that never showed up to reach out to him).

Deserved the F, next.

 

[daveyinaz]

The professor updated the syllabus saying so.

You must have read some other post that is not mentioned here because I didn't see anything bpatrick saying that he was informed of the mistake or change.

It's common knowledge that syllabuses are subject to change during the first few weeks (My stats syllabus reached it's final version in week 4).

I didn't realize the fact that your particular stats syllabus was revised a number of times made it common knowledge to all students in all colleges and universities everywhere.

If he's going to prance about like he's better than the institution, it'd have been wise to show up to class every once in a while.

Where did you get that bpatrick was implying that he was better than the institution? Must be the same invisible post you are referring to above.

It was not the professors job to reach out to one of his many, many students (especially one that never showed up to reach out to him).

From the information at hand, bpatrick said that he went to the professor's office hours for homework assistance, if that ain't reaching out, then I don't know what else is.

Deserved the F, next.

Here's what I think went down, assistant chair ahole professor knew bpatrick was not attending class and knew he was taking the tests, even so far as to let him take the final with full knowledge that he was going to fail him and then hide behind some bs like his job title or the fact that he made a mistake in handed out an old syllabus. The appropriate response as an educator or a man with any sort of integrity would to observe the absence pattern and warn the student beforehand of the situation that is about to occur should they continue down a course of wrongful actions, in this case, not attending classes.

Are you like 5 years old? I'm 100% positive that a professor has a MILLION better things to do then to punish one student who didn't go to lecture.

Do I think that it's stupid that someone who performed well in the class got an F because he didn't go to lecture. Of course. But did bpatrick not have the responsibility as a student to make sure that this was ok? He noticed he got a syllabus with the wrong year at the top, it would have been a good idea to clarify with the professor that this was indeed the correct syllabus, especially if he planned to never go to lecture at all.

I have ZERO sympathy for the guy. Sucks, but if you're going to take a semester long vacation, it'd be a good idea to keep up with the professor. The professor is teaching hundreds of kids I'm sure. It isn't his job to make sure that one student who never bothered to class showed up. Anyways, this whole discussion is off topic, and I apologize for making it so.

 

[Nano-Passion]

I think professors make the only difference pertaining to raising someone's interest, in my personal case at least. I don't want a professor who teaches by a book, because I can do that myself. But I would like a professor who connects bits and pieces together and gives the bigger picture.

Actually, bpatric didn't assume that the professor changed any substantial rule in the syllabus. If a professor gave me a year old syllabus, I would think that he did it on purpose and not by accident. But at any rate, the fuel of this argument relies on differing beliefs, one is practical while the other is absolute. Therefore, this argument will go nowhere. And let's not attack others for different personal characteristics (lenient vs. absolute).

 

[Jorriss]

Sucks, but if you're going to take a semester long vacation, it'd be a good idea to keep up with the professor.

It sounds like he wasn't if he got an A otherwise.

Higher education should be about education rather than attending mandatory classes which may or may not help

 

[mathwonk]

people who do not show enough respect to attend class deserve and receive absolutely no slack. Learn this before proceeding further. In my own case, I call absent students on the phone and make sure they know what is going down, and ask why they are absent, but I am totally unique in this respect. Again, if you sign up for a class and do not show up, you are going to suffer for that, and no responsible party in any appeal or forum will support you.

If I may interject, I don't believe its a matter of respect. But rather, a matter of preference. Some use lectures as their prime tool of study, while others prefer complete independent study.

I think if your paying to go to a school to learn something you should do both independent study and lectures.

 

[Jorriss]

I think if your paying to go to a school to learn something you should do both independent study and lectures.

Some people really do benefit from just independent study and for this student, when he needed help, he went to office hours.

 

[mathwonk]

you are missing the point. no matter what you think is preferable, you are not going to succeed in school if you do not attend class. we are not discussing whether that is what you think is reasonable, I am telling you how to succeed. Besides, if you are paying tuition to a school where the lectures have nothing to offer, you are a sucker.

 

[mathwonk]

To the student who got the low grade for missing class: it is possible you can appeal this grade and have it changed. At my university the university guidelines say that you can be dropped from a class for lack of attendance, so it is part of the written rules that attendance is expected. However I believe it is also a policy that the instructor must distribute a written syllabus in which he explains his attendance policy and the basis for his grading system. If this is the case at your university, I think you would have case that the written syllabus which was distributed should be the one that must be followed for grading that course. It is always worth a try, but you need to be polite to everyone involved if you hope to succeed. The first step in any such appeal is usually to simply speak to the instructor and make your case, as diplomatically, but clearly, as possible.

 

[daveyinaz]

I'm 100% positive that a professor has a MILLION better things to do then to punish one student who didn't go to lecture.

How can you be so positive? Are you the professor whom bpatrick is referring to? It's kind of sad really that you think there are "better" things to do rather than concern yourself with helping a struggling student as an educator/instructor/professor/teacher/whatever, especially one who has clearly shown potential since he was able to get good grades without attending classes.

Do I think that it's stupid that someone who performed well in the class got an F because he didn't go to lecture. Of course. But did bpatrick not have the responsibility as a student to make sure that this was ok? He noticed he got a syllabus with the wrong year at the top, it would have been a good idea to clarify with the professor that this was indeed the correct syllabus, especially if he planned to never go to lecture at all.

I definitely agree with you on this point. There are a variety of routes bpatrick could have taken where the end result might have been different.


Furthermore, comments like this have no place here...

Are you like 5 years old?

I always chuckle at remarks like this because I'm pretty sure someone like you wouldn't have the sack to say it to my face in person.

I have ZERO sympathy for the guy. Sucks, but if you're going to take a semester long vacation, it'd be a good idea to keep up with the professor. The professor is teaching hundreds of kids I'm sure. It isn't his job to make sure that one student who never bothered to class showed up.

Making statements about having zero sympathy for people certainly tells more about you than anything else said in this discussion so far. To be so arrogant as to think that anyone was asking for your sympathy is mind boggling when it seems that bpatrick's intention was a "lessons learned" kind of story and not one of "feel pity for me". Plus you do not know the whole story as neither do I to conclude definitively what really happened.

Anyways, this whole discussion is off topic, and I apologize for making it so.

On the contrary, I don't think anything said so far has been so off topic that merited an apology. It is clear now that teachers do make a difference, in so far as much, as random strangers are debating them on this very forum.

 

[mathwonk]

I think this is very much off topic. The gentleman made it about his personal gripe, instead of a general discussion.

That's your opinion, I still stand by my statement that it was not. The issue is; does a [math] teacher make a difference? It was a personal story where the teacher did make a difference. \blacksquare

 

[mathwonk]

he never heard a word the teacher said. the difference was only in the grade. it is hard to imagine how much farther off topic that could be, in a discussion which presumably was about how a teacher is crucial to learning. but i do not expect you to agree.

Yes, it would be hard for me to agree when one can read the post that started it all...

I was at my school's tutoring center and heard these two guys agreeing on how math teachers make a huge difference on how well you're going to do in whatever math class you're taking. Do you agree or disagree?

I bolded the part that said how well you are going to do...which includes grades.
