Kobi Abayomi

Jun 2006

I've read Kobi's other reviews and after taking his class this is my statement: If you are willing to work to learn the material you will love Kobi's class because he really wants you to understand and loves statistics. If you don't want to work and just want to get past the course you will not like Kobi and will have a hard time with the material. His tests are not the "regurgitation" type: you have to understand the material to do well. And if it is worth anything to say, I got an 'A' in his class.

Kobi Abayomi is, without a doubt, the WORST TEACHER I HAVE EVER HAD. He managed to make concepts that should have been easy to understand absolutely impossible to grasp. His writing was illegible and students were constantly forced to correct his calculations. He put problem sets on Courseworks, but often neglected to post answers. At one point, I asked him if he could put answers to a practice exam online, and he laughed in my face. Data for projects was posted a few days before the projects were due, making it impossible to avoid having to do all the work at the last minute. Attending lectures is pointless, as the only way to understand concepts is to read the entire text book. Students who had taken statistics classes previously did fine in the class, while those who had never been exposed to Stats had absolutely no idea what was going on. Kobi seemed to think that the success of the students who had taken classes before was a reflection of his teaching. When I expressed dissatisfaction with one of my test scores, he told me that "other students got A's." Not helpful. AVOID TAKING ANY CLASSES TAUGHT BY KOBI. YOU WILL BE CONFUSED AND FRUSTRATED ALL SEMESTER.

I found this class to be challenging and rewarding. I started off with a low C on the first quiz, but after meeting with Kobi a few times I was able to turn things around and end up with an A in the class. Kobi really pushed us to challenge ourselves and to think through these concepts instead of simply memorize them. Math is not my strong suit, but now that I've walked away with an An A in this course, I feel like I can succeed at anything Columbia throws my way. There were a few slackers in my study group who complained a lot about how hard the material was. They didnt seem to want to come to class regularly or put in any effort, but in the end more than a third of the class ended up getting an A. One thing that really helped me was Kobi posted every lecture on the web so the few times I had to miss class I was able to stay caught up.I found the quizzes were pretty easy if I did the problem sets and read the lecture notes from the web beforehand. All in all, it was a very rewarding class, and I feel fortunate to have had a professor challenge me to believe in my abilities even though I have always been initimidated by math.

I disagree with the previous reviews. I thought Kobi's class was challenging, not difficult, and he did his best to make the grading extremely fair. I actually did go to his office hours regularly: he has a way of making you find the answer out rather than just telling you. Looking back, while the class wasn't easy, I learned alot.

DO NOT TAKE THIS CLASS!!!!! Simply the worst teacher I have ever had. He writes the wrong equations on the board, gives quizes that dont cover what was taught in class, and simply cant explain even the most simple concepts. Everyone was always confused and I basically had to teach myself everything through the textbook.

Jan 2006

This semester was Kobi's first time teaching his own course, and it showed. He definitely viewed it as a hassle and did not put very much time or effort into it. At the beginning of the semester, the quizzes were easy because they were identical to the problem sets he gave us a day or two before. However, just as we got comfortable with this system, he apparently became lazier and stopped making lecture notes or problem sets for us, also cancelling quizzes (though not telling us until he had kept us in class for more than 30 minutes) because, I suspect, he didn't get a chance to write them. If he runs his next class like this one, do as well as possible in the beginning of the semester so once it descends into chaos, you'll at least have a good enough average to compensate. He's a nice enough guy, but not a very good teacher.

Not only was he the worst teacher I ever had, I think he is quite possibly the WORST TEACHER IN THE HISTORY OF THE TEACHING PROFESSION! Kobi never, ever explained anything clearly. Everyone in class was always ocnfused. He rushed through lessons without explaining the material and why it was important. We had wekkly quizzes which often contained material we had never gone over. In the beginning he sent out practice quizzes before the actual quizzes, but often doing so the night before the quiz. But the absolute worst thing about him was hiS ATTITUDE! He is the kind of teacher that makes you feel stupid. He often made smug comments when students would ask him questions. He would often let out annoyed sighs, roll his eyes, smirk and chuckle when students asked questions he thought were simple. It was horrible seeing him in office hours because he was just as bad. The TA was a little better, but even she was confused by some of the work he would give us. I took this course for my major and it was supposed to be the easy one, but he made it a nightmare because he just can't teach! If you see his name anywhere on anything, do yourself a favor and RUN!

So the deal with Kobi is that he's actually a pretty bright guy, but doesn't seem to be very interested in teaching undergrads the basics of stats. The result is a pretty crappy intro to stats experience where you'll learn minimal info and will suffer through boring lectures and brainteasing quizzes on material that he didn't teach well (sorry for the long sentence). I'd definitely recommend staying away from his section because he won't give you or the class the attention you need to understand basic stats. I ended up doing fine in the class, but that's only because I was able to BS through the quizzes, but many people ended up pass/failing because they were getting B's and C's on quizzes and Kobi didn't seem to have much mercy on them. Overall, don't take this class, take it Tian Ziang or someone else who actually cares.

kobi was one of the worst teachers i've ever had in my life. the expectations were unclear the entire time. we had quizzes once a week (which lasted the entire length of the class) on material we were never taught. this left us with one hour per week to learn new material we were to be tested on the following week. needless to say, the pace of the class in combination with the poor teaching quality makes it extremely difficult to say anything positive about him. addtionally, he has very poor hand writing which made note taking very tedious, and whenever we asked a question about the material, he answered as if he was annoyed that we didn't understand. the book that is used for this class is extremely convoluted, so it is important to find a teacher that has the patience and skill to relay concepts. kobi has neither of the attributes.
