I thought he was refreshing in comparison to the professors of 211: funny and friendly. He obviously loved the topics but had a tendency to think everyone understood it as well as he did: thus the tests were failed. He was obviously upset by the scores and made an extra effort to improve them (so much that the next test was offensively easy).

Obviously Bio isn't a breeze, but but Chang tries to make it fun. The tests are fairly easy as long as you actually read the material and listen in class. Just be careful not to sit in his microphones dead spot, or he'll blame it on you!

He is hard with his plant and cell biology, but his tests were easier to take and it was easier for me to understand him when he was talking. His tests are actually funny to take because of some of his multiple choice options. You do have to pay attention though, you do have to study VERY HARD, and you do have to read the book.

Jeff Change is a great professors. His material was easy to understand. He doesn't try to make his tests easy at all. in fact some of answer choices for his test is quite funny. He gives you the facts in class. all you have to do is memorize it. You don't have to read anything more out of the book.

Great professor. Hard material, so GO TO OFFICE HOURS. 1st time I went, soon as he knew my name he knew everything about me out of 1400 students! If you put effort in, HE WILL SEE YOU SUCCEED! Again, GREAT PROF!

He's a funny and amusing teacher. The class time is fun, but he does get off topic a lot and sometimes it seems annoying. He says ass a lot and relates some material to newer and more understanding things. Great teacher to have, but he didn't teach the whole term.

He is a good professor for the most part, but does get off topic which gets frustrating. He might have ADD. He can be a little rude too. His teaching style is good and his tests are not difficult, although a few questions should have been thrown out that he kept. He makes it a lot easier than he sounds like he will, and you learn a lot from him.

He is straight forward, follow his slides and review them before tests and you will be fine. Tests can be hard, but can be quite simple as well. Makes funny remarks, and is obsessed with bagels and the 49ers. Overall a good instructor, but can be challenging.

Really great professor , easy midterms

He is very funny, especially considering the information he's teaching is a bit dry. His lectures give you the basic outline of what you need to know, but I suggest opening your book (sorry, I know it's painful) and reading the chapters. His multiple choice questions almost always contain one or two obviously wrong answers. I liked him though!

You must take advantage of his first two tests in order to tank the final for an A. Chang's exams are very straightforward and usually have 2-3 obviously wrong answers per question. Best BI 2xx instructor, and an interesting man. Got an A but had to work for it.

Jeff is very entertaining and made class fun. He does get off topic easily though. Tests are pretty easy, but some questions can be tricky. Overall a good professor and I would recommend him.

I'm not sure what everyone is talking about here. I never read from the book and did fairly well on the tests. All I did was study the lecture notes from class and was able to get high Bs on both tests (well enough to get an A in the class overall). A few trick questions, but nothing unreasonable. Pretty funny as well.

The topics in this class are CRUCIAL to understand for upper division Bio courses. Dr. Chang makes the class challenging because he knows how important these topics are. Read the book and go to his office hours; he is incredibly helpful in person! Don't just complain about not getting a good grade but refuse to put in the work!!!

I'm not sure what everyone is so upset about. Is this class challenging? Yes. But, it should be. I never read the book... just watch and take notes on the pre-lecture videos then come to class ready to do an activity. If you are stuck on a topic, you can get help in class. Most people complained more about the activities than actually tried them.

Dr. Chang is the lecturer for the first portion of the BI212 course, as his focus of study is Botany, he taught everything in the course on plants. Although I audibly heard complaints from other students, I found his lectures informative, and he is willing to make office hour appointments with you to help you learn the concepts. He's really nice!

While I do agree that D. Chang can sometimes use confusing vocabulary or call students out, he really appreciates when students engage and will happily answer questions. Make sure to be attentive, he can talk fast and very concisely. I would take his class again.

I love Jeff, I think the people who say hes rude are misinterpreting his response to questions. He can be a little sarcastic but its clear hes joking and trying to make lectures fun. He is very thorough at explaining things and more than willing to go back and answer any question. By far my favorite biology prof at OSU.

I don't know why people are saying Dr. Chang is a bad teacher. He tries hard to keep the class engaged during difficult topics, answers questions well, and even though the tests can be hard, there is tons of extra credit to make up for it. I only do the pre-class lectures and occasionally the study guides, but his lectures are usully helpful enough

I had Professor Chang in person for BI 222 and I definitely prefer him over Lori(ew). His written notes are a little confusing to follow sometimes during lecture but he is so open to kids asking questions and is willing to take the time to answer them during lectures. Lots of kids were comfortable asking him questions during lecture. Very witty.

Im not sure why Jeff has a bad rep, he is genuinely so caring and interactive with his students. He always makes sure to answer all questions during lecture and makes that 50 minute class very enjoyable and quick with his jokes and sarcasm. He is definitely the BEST one out of all the gen bio profs that Ive experienced. No doubt

Great professor and very funny

Dr. Chang has absolutely been my favorite gen bio professor. His lectures were very entertaining and he makes it easy for students to ask questions throughout the whole lecture. While the content is difficult, but he made it easier to understand because we could address the things that he maybe didn't explain so well the first time around.

Professor Change was such a good instructor. Rather than getting a goal completed, he actually wanted us to understand the content, compared to other instructors in the series. One thing he didn't do well was responding to questions about specific details in the content.

Chang is an amazing lecturer. Teaching biology concepts is difficult but he manages to break down the mechanisms simply. He answers questions very nicely and considerately. His lectures are hilarious as well. The class is very exam heavy, so study for the midterm and you will do well in BI222

He's hilarious and he's good at explaining or elaborating on topics that people in class struggle with.

Best prof I've had so far! Very engaging

My favorite Prof thus far in the BI series classes. Good at explaining topics on multiple levels for students with varying degrees of prior knowledge. Will draw rough sketches to help depict the topics better and for those who are keeping written notes. Has a sense of humor that helps to keep students engaged and listening to the material.

He is a lot better than Lori, like A LOT better. He honestly is really good at going over concepts so far and makes good analogies that go with the concepts being learned. He also goes at a pace that is easy to follow and is willing to take time to answer student questions and go back over content that was confusing.

He is the best Bio prof at OSU as of 2024. He really tries to make sure everyone understands. Bio is one of the hardest subjects because it is ALL memorization. You can not just go to lecture and score well on exams, you really have to study.

Overall, good professor who cares and can add humor to lecture. This is a flipped lecture where you read or watch videos and do work in class. Typically I dislike flipped lecture courses but I liked this one. I recommend him

This is an introductory class, but almost everyone is a grad student working in a lab, so undergrads will feel very lost. You work in groups for the entire term, and many classes are literature review group presentations. Attendance is recorded but participation makes up your grade. Extremely kind grader, but I wish there was less group work.

I love Jeff. This class is almost entirely participation-based. Homework was mostly asking you about what you know on a subject. We read a lot of papers and discussed them. The content and papers can be confusing as an undergrad, if you aren't used to reading them. As long as you attend class and talk to participate, you will get an A.

He's a great and funny guy, but his style of lecturing isn't for everyone. The slides used have little information, so I had issues whenever I missed what he said where I wouldn't have a clue what was happening with all the abbreviations/acronyms written down. That aside, Jeff does cares for his students and I still found this section enjoyable!
