He was a fairly good teacher, always ready to help with problems, made jokes all be it corny ones to try and make his students enjoy his class. Is a better alternative to other teachers that teach 211-212.
He never really helped me with anything. If I had a question, he answered it by explaining some loosely related mathematical conundrum. I've always been a good student and had A's or high B's in math, but I studied my butt off and hired a tutor and made a C plus.
expects you to know everything.
Very lazy, and unwilling to help
He was not helpful and did not review material well. His manners are also much to be desired. He once passed gas in my face while I was in his office and did not say excuse me! I couldn't even get the help that I needed because of this rudeness. Even when I went to his office other times, I was as confused as when I walked in!
this class was ridiculous, i eventually stopped going because i always ended up more confused than when i went in. i stopped in his office many times, and to no avail. he expects you to know everything already, and often goes back and forth between irrelevant material.
Not a bad teacher. At least he could speak english. His test were easier than his homework. As long as you put an answer on a test you get half credit.
Basically, he just sucks at teaching.
He's hard. He forces you to stay on top of things, but he is fair in that the homework is extremely challenging, but his tests are always much easier.
Just switch teachers, you'd definately be better off. He is a nice guy out of class, but it's not worth the trouble. He makes everything 1,000 times harder than it should be. If you just want to read the book and never come to class, go for it, but if you want to learn and make a good grade, get another teacher.
this guy is psycho...he's incredibly tough. get out while you can! he's extremely unhelpful.. and makes things 100x harder than it has to be.
Nice guy outside of class, easy to talk to and joke with. However, when it comes to presenting information in a clear- easy to understand way, Mr. long falls short. If you are brilliant and pick up things super fast, he's your man. Otherwise I recommend someone else. He knows Calculus so well I think he expects everyone else to also.
drop the class!!!
Funny teacher. Enthusiastic. Very understanding when it comes to grading material. Curves tests occasionally. Tests are easy if you have a basic understanding. A lot of individual studying is required. Goes too fast in lectures (but i am a freshman not used to college yet)
J. Long is probably one of the best math teachers I have ever had. His graded hw assignments force you to learn the material extremely well, so that you can do well on his tests, which are much easier and very relevant to his teaching and very similiar to the graded assignments. He likes students who show alot of interest in his class.
Pretty good teacher. He tries to make sure every student understands, but he doesn't always do the best job of being clear. That said, he is a very fair grader and gives partial credit.
If you like to teach yourself the material, he's your man. A lot of hours learning the material before doing homework. HE CUTS SLACK AT THE END OF THE YEAR, so if you deal with mediocre scores for the four exams,you'll do fine. Learned a lot, grading was very fair
Hes OK at best
The teacher is known to be hard. His class requires alot of time. So if you already have a heavy course load, I would HIGHLY recommend taking another teacher. Although he is hard, he is easy to talk to and helpful. There are no quizzes, he assigns homework that is collected two times a week (but it's optional).
A nice guy, once I accidentally locked my keys in my car and had to turn in my homework late, he didn't even mark off. He only said "Well at least the homework was safe", however, his homework and tests are very hard some problems I did not even understand the directions much less the actual mathematical problem. You must study a lot.
Long's not very good at explaining things, but he's pretty lenient in his scoring. Show up to class, the tests will seem easier that way, since he makes up the questions himself. I heard he gave a good curve at the end of the semester, but most people were struggling in my class.
This class was very stressful. The biggest problem is that he didn't teach from the book, yet the homework was from the book. I spent way too much time trying to connect his lectures and the text. He's a very nice man and almost always willing to help. But, his advice is rarely helpful (or comprehensible). He did curve the final grade by a lot.
This class requires a lot of outside study time. Be sure to go to class.. many of his test questions are based on class lectures not from the homework.
John Long is a really great teacher who will take interest in your success if you go to classregularly and talk to him. The homework is mandatory and normally hard, but the tests are easy in comparison. He gives partial credit for work on all homework and test problems. Take him!
Very good at explaining the concepts and how to do the problems. Tests are easier than the homework problems. One of the better math teachers
truly a great teacher. he knows everyone by name and takes care in whether you pass or not. He's tough. Calc 3 is hard stuff but he does a great job at teaching it. take him!
Dr. Long is pretty much a genius when it comes to calculus--he really knows what he's talking about. He gives out 2 to 3 homework assignments per week. The tests are usually easier than the homework but sometimes aren't exactly like the homework problems. Even though it's not the easiest class, he's a great professor to take for Calc III.
hard class. but he gives lots of partial credit, doesn't count all of the homework points, and curves A LOT at the end(he also speaks english, which is a rarity in this department). You may feel overwhelmed at the beginning, but he makes sure you come out with a passing grade. I ended up with an A- though I struggled most of the time.
John Long is a good math teacher. He really knows what hes doing and enjoys it as well. He is generous to his students and his tests are reasonable. From what I've heard, he seems to be middle-upper class on the teaching scale comparatively. If you study for tests, do your homework, and listen a little in class, you pass with a B or A. Curves too.
He is a very nice guy and really knows his stuff. Really hard to understand in lecture. he doesn't seem to be able to come down to the student's level. Always willing to help and will accept homework late and curves. I came out feeling like I learned something, but only because I worked really hard. Tests are hard, but overall a decent teacher.
He really knows his stuff. He seems to have trouble relating to the students in that sense. Really nice guy,but you've got to work at it. Homework's hard, but he curves. Tests can be really hard too. If you want an easy teacher, he's not your guy. But overall, I was satisfied.
Terrible teacher! I made A in Calc 1 and B+ in Calc 2. This guy cannot teach! I studied my butt off and the exams were nothing like the homework! His notes were somewhat closer to the exams but still pretty far off. He was very lazy in his concept explanations. I WOULD STRONGLY SUGGEST TAKING ANOTHER TEACHER FOR ANY AND ALL MATH COURSES AT UT!!
John Long is extremely hard, but makes sure you learn the material. He also recognizes he is very hard and thus grades accordingly. HE IS VERY FAIR WITH GRADING EVEN IF YOU STRUGGLE ALL SEMESTER
Hard teacher, on another level than the students, I learned EVERYTHING from the book because he was speaking jibberish to me. He is a fair grader, and an interesting person in my opinion, not a boring teacher. But you just can't understand him.
HARD CLASS. He knows what he's talking about, but no one in the class does. He's all over the place. Constantly getting off track. Everything I've learned has been from the book (which is horrible) and from friends. He's just BAD at teaching. REALLY BAD. Get a different professor if at all possible.
The worst math teacher at UT. Run! If your a math genius you will be fine. If you made it through Calc I, II by hard work, you won't make it in his class. I had A's in both I and II and made a C-. Run I'm not exsadurating
Hard teacher but definitely knows what he is talking about. take advantage of the book and the math tutoring center or corner him in his office!
Absolutely terrible at teaching. Does not explain the fundamentals of the material at all before elaborating on complicated details and/or methods on the subject matter. Does not care about student performance or learning, and is of little assistance after class. Testing is arbitrarily difficult. This man should not be allowed to teach anywhere.
Don't expect to learn anything from lectures, the main reason for going is to turn in homework. Most lectures turn into tangents where he shows off all of the math he knows, but that is not needed for the course. Check his website frequently, he conveniently forgets to mention tests until the week of. Will NEVER take him again, ever.
He was a good teacher, but I had difficulty grasping the material, but he was extremely helpful with every question I had. He was actually a good teacher. Attendance isn't madatory, but you will have to go to class to turn in the homework. He doesn't accept late homework either. I ended up with an A-, but it was difficult material.
One of the worst math teachers ive come in contact with. First of all his method of teaching sucks. most of the time he doesnt tell you what hes going over, he just begins writing and expects you to know what hes doing. Also he wore the same shorts/ pants all semester and never washed them. I had to join cramster to understand what he was teaching.
:( I got stuck in the 8am. However, Dr. Long was cool with my attending the 10. He is very funny, super laid back, and if you do well on the tests HW is no so important. Speak up. He'll let an awkward silence drag on to spite you. He tends to dive into topics without much pretext, so keep up. Attend office hours. It'll help.
Dr. Long is a very nice person, but his understanding in math is a much higher level of thinking than calc 2 students. If you have no previous knowledge of the topic before the lecture it is very hard to pick up where hes going as he doesnt define what hes going over, he just kind of rolls from one topic to another
Even if you have no clue what's going on in class, write down all your notes anyway because they will help you study. Homework problems are hard but he'll explain problems very well when you ask him. The tests are much easier than homework so don't worry if you struggle during lecture.
If the chapter is read before class, his explanations are much better for re-enforcement. Overall, his teaching style is a relaxed environment, where tangents can be frequent trips into the history of mathematics.
Hw is curved but can be hard. Tests are not curved, but tend to be easier (although sometimes a bit outside the box). Very nice guy - willing to help whenever you ask. I was able to follow the lectures but was in the minority. Expect to learn from the book on your own time and work for it.
Absolutely the worst teacher I have ever had. He tests on things other than the material covered, spends lecture bragging about how much math he knows and doesn't tell you when your having a test until the day before. Do not take him unless he is your only option. He should not be allowed to teach by the University!
Very smart and sometimes forgets to water things down a bit for students. However, he is very nice and understanding and will help in any way he can. Attempt all homework assignments and show up to class and you should do fine. Also wouldn't hurt to stay ahead in the text before lecture.
Professor Long did a very nice job teaching Matrix Algebra 1. He explained the material well. The homework assignments usually consisted of about 10 questions per assignment.
Dr. Long is very smart and willing to work with you. However, you need to expect to basically teach the entire course to yourself. He teaches with a theoretical approach and often goes off on long tangents. His examples are almost impossible to follow. Homework is curved and he allowed us to correct one test which helped.
I loved him! He's a character and makes class interesting. You definitely have to pay attention to get an A
This man is so unclear. Very frustrating. His lectures are not structured, and it's almost impossible to get a perfect score on homework assignments. He sometimes says funny things, however you will not learn much without your textbook. I do not recommend.
Dr. Long is one of the most confusing professors I have ever had. This man is extremely intelligent but TERRIBLE at explaining information. I had calculus in high school (and an amazing teacher, I might add) and I feel like I'm taking an entirely different class. I would recommend avoiding Dr. Long if you have the option.
Worse than useless. Tests and lectures didn't cover the same content. Class average on the first test was a 38...this turned out to be the highest average of the semester. I sat through every lecture... Should've gone fishing. Guarantee I would have learned more about Calculus on the river bank.
This guy is something else. I have to say I really like him and I bet he would be fun to chat with if I had about 50 years of math under my belt. I am very technical with regards to math and that's how I best learn it. Mr. Long is beyond abstract. I would recommend you not take him for anything below a 300-level math course-or you better be ready!
Dr. John Long does a great job teaching Calculus 3 (Math 241) However the difficulty students have with Calculus 3 is misconstrued as lack of effort or ability to teach on Dr. Long's part. NOT SO!! Best Calc 3 teacher here!
His teaching style is very abstract, but the exam questions are not (for the most part). He grades homework harshly, but the curve at the end is so steep that it doesn't really matter. You need to learn from the book and from YouTube to do well. He answers any questions very clearly, though, even if you ask him about specific homework problems.
Dr. Long is a truly great teacher. Although other people bash on him, I am positive it is because they have no earthly idea how to do math on at least a basic college level. I had him for Calculus II Honors. His tests are incredibly reasonable, the homework is hard but makes you learn the material. He is funny, and loves if you visit him.
Dr. Long is very funny and totally chill! He can be a little abstract, but is very easy on late homework, etc. Not my first choice, but good.
his class is very easy if you actually put the effort into homework assignments. He's super funny. He does curve and want his students to get good grade so if you go to office hour often, your grade will be fine. I enjoyed this class a lot, it was my easiest class of the whole semester because I didn't have to worry about my grade.
Terrible teacher. Very smart guy, but he often works problems incorrectly on the board. Also, most of the time he is very unclear of what he is teaching. If you have never taken calculus before, you will NOT learn anything in his class. Tests are fairly easy. I would NOT take his class again.
Dr. Long is truly a great professor. I don't care what all these fools say on here about him being hard or bad or unclear, because they obviously are crappy at math in the first place. Dr. Long is a laid-back, extremely helpful, and kind man. He will go out of his way to help you do well, and his tests are super easy if you do the homework.
He doesn't really make sense in class, and definitely doesn't explain things. There is Webassign every day before class. He usually provides a practice test which is 75% similar to the real thing. Get ready to teach yourself or visit the Math Tutorial Center.
This professor is a math genius, no denying that. Unfortunately, he is not very good at communicating the concepts clearly. He forgets to dumb things down a bit for Calculus II students. Also, be prepared for a lot of homework assignments. Other than that, the exams are not hugely difficult. If you study for them, you should make a decent grade.
Sometimes lectures are confusing. Spent a lot of time in the math lab getting help. There is A LOT of homework, but do it! At the end he only requires you to have a certain amount to get a 100 on hw. He is a lot of help if you go to office hours, and he helps you out at the end of the semester if you show that you try. Book is only for your benefit
Dr. Long is a different kind of professor. I felt like he rambled off random math half the time before I began to understand it. HW was optional, he didn't collect it, but we had about 11 quizzes. These were easy, especially when he had examples pretty closely resembling the ones on the board not erased. Tests were not too hard
John Long was a very difficult professor. He usually rambles on in lectures and he's not much help in class. Also, many of the subjects he teaches in class don't exactly match with the homework, so expect a lot of confusion and time spent outside of class trying to cope with not understanding what is going on.
Professor Long is very brilliant at math. His lecture can feel a bit long and he does go on tangents a lot. But he is also quite funny and will answer questions in detail when asked. If you show effort and put a bit of time into reading the book and completing homework's you will find him to be very helpful in terms of grading as well.
John Long is possibly the worst professor i've had. While, he is a quality guy he is impossible to understand during lecture and frequently rambles on about completely irrelevant topics. I am beyond frustrated with this professor, and i can't speak for other course; but I recommend that if you are taking this course you find a different professor
John Long was by far the most confusing math teacher I've ever had. I'm usually a pretty good math student, but he made me feel like I know absolutely nothing about math. Everything he talked about made no sense which affected my grade. If at all possible, do not take this teacher.
If you pay attention in class, you should have no trouble making an A in his class . If you are confused about the way he explains something during class, his office hours are a good time to look for some clarification. Takes up homework in class, but if you miss then you can find all of the missed info in the textbook.
Great teacher, makes you think about the processes behind what goes on. Homework can be tough but he thoroughly checks and gives out partial credit if you were taking proper steps to a solution. Same goes for the Tests he gives out. If he is doing work in class that you do not understand, ask him about it and he will easily make it understandable.
Very good man. Very bad teacher. He's more interested in showing you how to tackle the hardest problems ever known to man than actually teaching the essentials of Calc II that are applicable to other courses outside of his own. He's always accessible when he isn't in class teaching. So, be ready to spend a few hours with him/day.
I can't bring myself to dislike this guy. He's kind of spacey, but he's really nice and does interactive things in math 113 like cutting out and making 3D shapes. For a class that basically doesn't exist, he is a little confusing, but between test and homework grades I think my grade will end up being okay.
This professor made this class very challenging. He was not very good at explaining himself and not very organized. Not much homework and not many tests. I ended up having to drop the class because I was not understanding at all.
I had Dr. Long for MATH113 and I struggled with the class. He is such a great man and is so caring, but he is hard to understand when he teaches. He doesn't explain what he is doing. You really have to take the time to teach yourself for this class. Only grades were 4 tests and homework. I loved him, but can't say the same about the class.
Longs class is easy if you try. Many of his lectures seem very spastic and unorganized but the homework following each class is the same material. If you pay attention in class the homework is a breeze and the tests reflect how much effort is put into the homework.
He always says "if you are confused than you're doing good" which makes no sense. I never understood anything in class, but I tried my best and I used the internet for the homework I got a D on the first test and a C on the second 2 but I have no idea what I got on the final and I ended up with a B-. Just let him know you are trying and he'll help.
Took Long for Calc 3 over the summer. He does not teach well at all. You will be watching Khan Academy and a lot of YouTube to get through this class. I basically just taught myself the curriculum. Contrarily he is readily available outside of class to help you which is sometimes helpful.
Long didnt really teach us, but instead went over problems in class. He was quite shallow in demonstrations of problems often skipping essential steps and not showing his work. Even when asked to explain problems he didn't really explain his thinking or the steps to solution. If you take this class bring your A game, and teach yourself everything
He is a really funny, but the lectures jump straight into very complicated examples, so the basics are never covered. There is lots of difficult homework and the tests can be pretty hard, but he is generous with partial credit.
He is a terrible teacher and does not go over the material at all. His tests are very hard and he does not prepare you at all. He goes over hard problems that has nothing to do with what you're learning. I had to teach myself everything.
don't take this man unless you have to!! math 113 is supposed to be super easy but he over complicates so many problems. I had to teach myself all of the material before tests. It is possible to pass but I had to work extremely hard (I'm also bad at math anyways)
Pretty brutal class; make sure you keep up with your work because you're going to be flooded with homework due at awkward times. Lectures aren't particularly helpful and they usually devolves into explaining the theory behind mathematical concepts, which you won't be tested over and will probably just confuse you.
He is the type of incompetent professor you fear having. He arrives late, mumbles, doesn't specify what he wants, goes on tangents that don't even connect with the lesson supposedly being taught, and, worst of all, just doesn't care about you or your grade. Take if you like teaching yourself everything, other wise avoid like plague.
These kind of professors are the reason most American kids are bad at math, he is just terrible, he mumbles and not very organized. He is smart you can tell, but shouldn't be lecturing in a school like UT.
He really does not teach the material needed to be taught. In order to learn the material we had to hold our own reviews and teach ourselves the material. I am sure he is a much better lecturer for higher level math classes, but he obviously does not need to be teaching precal. Do not take him unless you have to.
Be warned: he does speak quietly and his explanations tend to focus on theory, rather that practicality. Personally, I didn't have issues with him as a professor, although I did have to teach myself a good chunk of the material. Make sure you go to class--he loves pop quizzes!
Maybe it was just me, but I did not learn anything in this class. He did not explain things at all and I felt so stupid the entire semester. He's probably a better teacher in higher math classes but he just does not teach precalc well. I would recommend taking someone else for precalc if possible
Smh, I'm surprised UT hires this kind of professors.
John Long is the worst math professor I've ever had. He is horrible at explaining any concept in Calculus 2. I have had to teach myself literally everything. It blows my mind that this guy is still allowed to teach at an educational institution.
John Long is the worst pre cal professor on this campus. He would walk into class every lecture and ask what we wanted to learn. Also, he would rarely have any problems for us to practice. Pop quizzes. We even had to go to the department head. Avoid at all costs unless you already know all the concepts in pre cal.
one of the worst professors I've ever had. Starts every class with "So... what do you wanna know"? ,and often gets his own questions wrong while saying "Ahh it's all pretty much guess work anyways. A Jolly guy who's lazy and has no idea how to teach so he just writes equations on the board whether they relate to the topic or not.
