Loves teaching, care about student success, difficult yet rewarding, many different ways to ear a good grade

Duncan genuinely wants you to leasrn and be the best you can be. He has high expectations but he wants you to succeed. All you need to do is talk to him and he will be a lot of help. Also for GB1: read before lecture and go to SI if you want an A. That simple

I must say that Dr. Duncan is the best teacher I've had in college. He helps integrate the material in the book, and unlike most teachers who just paraphrase powerpoint slides, Duncan brings in outside information/perspectives which helps make the material memorable. I have a C- right now but without Duncan's lectures I'd probably be failing.

great teacher. cute butt. he really does have an interest in student success. helps alot to goto office hours and si. also funny...for an english. defintetly read the material before class, helps to come up with questions in class.

Great teacher, honestly. I had taken GB1 and was so unsuccessful i had to take it again, and the second time around i got Duncan for a teacher.By simply studying his lectures and his review sheets for each weeks quiz (yes each week)i was completely prepared and ready for the final with no need to cram,just skimming old notes and quizzes.Got an A :)

Great teacher. He makes you do a lot of work but if you are a Biology major this is the class for you.

I'm more of a number person. So him not including no multiple choices at all bothered me. it's all about writing and essays. grading criteria is based on your understanding skills by writing bunch of paragraphs. :(

I thought he was a great professor. If you do the work and study, you will get an A. If you don't, you might perish. Dr. Duncan has a vested interest in helping students succeed. He makes a lot of resources available to his students, it's your choice whether or not you use them.

Todd Duncan is a good teacher. His class was intriguing and required your attention but was riveting. He helped me understand that biology has a basic level from cellular to system to the biosphere, and that having the foundation down will tie into everything else later. Good class and good teacher. recommend using office hours for your benefit.

Dr Duncan does a great job of making sure his students understand the material he's teaching and apply it to various related concepts. If you put in the time and effort, use all the resources he provides, you should have no problem doing well in his class.

Video tapes lectures so you can watch them online

Dr. Duncan doesn't give you anything more than the tools to do well in his class. Everything else comes from discipline, hard work, and a commitment to do well. If you do poorly in his class its your fault! He has deepened my understanding of bio and has taught to think critically. My fave teacher!

Dr. Duncan is a very good teacher. However, he is not very approachable, and sometimes he is rude to students. His weekly tests are EXTREMELY hard. While I believe I've learned a lot from this class, I also believe he would be better off teaching upper-level biology.

Dr. Duncan is an extremely good professor. He expects nothing except quality from his students. It is understood that you take responsibility for your own learning. Go to class, do the homework, and study -- and duh -- you will get an A. Best for pre-health students.

If you pay attention in class and watch the lecture capture you have no excuse for making a bad grade. His tests are hard but all the material is in the lecture and he provides tons of supplimental study material. You are given all the tools you need. If you seek help he will give it. He is blunt. He will not candy coat anything. My favorite class.

A true professional.I had Dr. Duncan several semesters ago and he is still the standard to which all of my other instructors are measured. His classes are not easy but he has by far the best framework for success I have seen. Take advantage of all resources he provides including the Socratic notes and take class seriously. You will be rewarded.

Dr. Duncan is the best professor I have ever had. His weekly tests are a little difficult, but just make sure you study the learning objectives and you will do alright. He makes all of his own power points and really makes sure that you understand the material.

Dr. Duncan is an AMAZING professor. He expects you to work hard, and actually UNDERSTAND the material. The weekly quizzes are not hard IF you study. Attendance is mandatory, he does "clicker questions" that helps out your understanding of the material, as well as your grade. I took both BIO 1 and 2 from him. HIGHLY RECOMMENDED for Pre-Med students.

Dr. Duncan is the best professor I have had. He gives tests the begining of every week, but as long as you study the learning objectives you will do fine. He also posts all of his lectures online which is really helpful also. He can be kind of rude if you interupt him, so I would recomend staying quiet during lecture.

British accent!!! :)

Great class for pre-health majors. Dr. Duncan expects you know, understand, and apply material. He is entertaining, clear, and helpful. Do NOT interrupt or screw around in class -- he gets very irritated. His extensive use of technology is helpful -- take advantage of it. Sad he will be leaving after this semester.

Tod Duncan is an amazing teacher. I learned so much from his class. I wish i could have taken more classes from him before he left the University of Colorado at Denver. He expected a lot from his students but it came with ease because I learned so much from his lectures.

Hands down the best professor I've ever had. By no means does he make his class easy, but through his incredible teaching, and with a little studying, you'll do fine. I have learned more in the two semesters with Dr. Duncan than I have in all my other classes combined. Sign up for any class he is teaching!!

Duncan was by far the best professor I had in collage. He is very clear about what he expects from students in class and outside of class. His exams are by no means easy, but if you use the tools that he provides, there is no excuse for doing poorly. He is always prepared and will put you in your place if you choose to be annoying and unprepared!

So happy I took Duncan for BIO I! His weekly tests are worth 50% of your grade and always read them very carefully. Just be sure to know the material very well each time. He makes himself very available to students and has always been available online. Always go to class both for in class assignments and his lectures are exciting and helpful.

Dr. Duncan is the best professor I've ever had, bar none. He is difficult, but I've never learned under anyone so passionate, knowledgeable, and clear. You will work quite a bit, but will learn so much.

Great teacher! I would definitely take another course with him. You will work for your grade but you will learn a ton.

I was challenged to think critically and learn to read/understand tough journal articles. These skills were also honed w/different assignments--the typical essay w/a word limit (to ensure succintness), as well as debates and presentations. He also made himself available during office hours and online. Truly a great teacher.

Though the Bio 1 class is large, you don't feel lost in the crowd. Learning assistants and Dr. Duncan will walk around the room and help with certain ideas.He uses a lot of good visual imagery to make his point, great if you learn visually. There is also a great online presence where you can ask questions and get extra help online! I recommend!

Awesome professor! Very clear in his presentations, gives you everything you need to know for quizzes and tests. Very helpful outside of class, always emails back! Taking another class with him definitely!

A very good professor who had a lot of resources to help you. You have to work for the grade, but in the end you learn a lot from him

I absolutely love this guy. He is helpful, resourcefull, and always there for his students. He likes to test your knowledge of the topics using slightly twisted questions, but you'll do fine as long as you study the learning objectives. Take his class, You'll love it.

He expects a lot out of you, but provides many resources and tips to help you be a better student and more importantly, a better scientist. I learned so much and was really inspired to broaden my knowledge horizons. I'm sad I had him in my last semester b/c I would have loved to take more classes from him. 10/10 would take his class again.

Hard class but he has a sense of humor and eases up towards the end of the term.

He is a very good teacher! He is organized and is there to help out his students. He set the bar high for all of my other classes.

Duncan has been one of my favorite professors. His class is GREAT if you're going into the medical field. He is not an easy professor, but he is willing to help students. I found he is willing to take a lot of time to help if you go to office hours on a regular basis. Go to class daily. There is a weekly quiz and iClicker questions.

Dr. Duncan is a GREAT professor but doesn't slow down for those who can't keep up. He is very clear and class is fun if you've done the reading, but if you fall behind it's all on you to catch up because he waits for no one. Being successful in GB1 is completely up to you. His lectures are easy to follow and he's a funny guy. Overall, great class.

Very difficult class. Meant to be a weed out class and Dr. Duncan's class does just that. Don't miss class. Take notes. Particpate with class activities. Note cards with detailed drawings helped. Enroll with a weekly tutor at school. Chemistry for biology students book was really helpful. Great Teacher! any problems, go talk to him. Struggled B-

Hands down the best professor at UCD. Had him for GB1, GB2 and Micro. He has hard bi-weekly quizzes that you MUST study a lot for. But he is fair in the questions he asks.

Attendance was not mandatory, however it is required to complete the work required for the class. This lab course is an upper level course and a good working knowledge of cell biology is needed to complete the assignments.

The quizzes and exams are very tough; however, you learn an amazing amount. Great professor.

Dr. Duncan is a creative professor and explains things very thoroughly so that you can grasp concepts forwards and backwards. His quizzes are tricky and rarely straight forward. Tests are also very difficult and he expects you to be able to expand on the basic things learned in class. He can be a tad harsh but is a good professor overall.

Some of the best lectures ever. You are able to view lectures after every week as he uploads them to canvas, but you must attend class to receive clicker grades. His quizzes are hard, you need to apply the material in different ways. I do not recommend if you have not taken biology in high school.

If want to learn biology and are willing to work hard, then Dr. Duncan is brilliant (two words: learning outcomes...). People complaining about him being 'too hard' are probably Freshman used to high school level difficulty, or they're just lazy. Yeah, Bio I isn't easy... but, it shouldn't be. Can't handle Bio I? Then good luck in medical school.

Dr. Duncan was awesome! He is extremely knowledgeable about biology and is always open to questions. His class isn't suuuper easy, but you will learn a lot. I would definitely recommend him as a teacher.

I took him a few years ago and made a C+ in bio1 and B- in 2. It was ridiculously hard. That being said, Dr D shoves ENTIRE SEMESTERS into a week and every class you take from then on you'll get an A. Genetics, Animal beh, Micro, anything bio? A. His foundation jumped me far ahead of others for every other bio class I've taken. Plus-that accent :)

This is the deal, Dr. Duncan's class is hard, but you get what you put in. I am an Environmental Science major and was terrified of his class, but you will not find a professor on campus who works harder to help his students understand. He understands cognitive learning and he applies helpful methods, its up to you to put in the time!!!!

Dr. Duncan is clear since the beginning of the semester about the difficulty in his class. If you want to succeed in this class you have to put in a lot of studying hours. His weekly quizzes can be hard, but they also help so that you study frequently about the material. Overall he is a very good instructor with a passion for biology

Learned a lot in Duncan's class and I would definitely take another class with him in the future. This class required a lot of effort, but his exceptions are clear from the beginning. Look at the learning outcomes and really make an effort to actually understand the material he is trying to teach you rather than memorize it and you'll be fine.

Duncan is difficult. There is no denying that, but the lectures and supplemental materials he provides are extremely useful and the material makes sense if you take the time to access his resources. I hardly cracked open the book because Duncan made it easy to understand. He cares for the material and the students and is worth the work.

Very good lectures, he puts a lot of efforts into his teaching! The weekly quizzes are tough, so you must really study. Everything comes down to the final exam though which is pretty tough. But if you put in the effort, don't slack off, you'll be fine!

He cares. He explains things clearly. He is concerned with you leaving his class a better Biologist, presenter

If you want to understand biology then take Dr. Duncan. It is hard, it is rigourous and he is going to challenge you, but then again this is college. He expects you to put in the work and if you do not, then your grade will reflect that. He gives you the resources to succeed, it just depends on if/how you use them. UC Denver is lucky to have him!

I enjoyed this class for 2 reasons. 1) I love biology. If you dont like biology then you wont do good in this class. It takes motivation to watch his videos and get the material. 2) If you took Ap Bio Senior or junior year your set, even if you hardly paid attention. Make sure you do all the HW assignments!!!! And pay attention to lecture!!!!!

Good professor but you must pay attention to the lectures! He is good at explaining, but it takes outside studying to understand the material at the level he expects.

Dr. Duncan is in perhaps the most knowledgeable biology professor I've ever encountered. The material he teaches is complex, demanding, and difficult--he is not. I first met him when he filled in for one lecture for an absent colleague, and I learned an enormous amount in just one hour. I can't thank him enough for making me a better scientist.

How to get an A in Dr. Duncan's GB1: Skim the chapter before lecture -- just skim. Go to lecture, pay attention, take notes. He breaks down the hardest material from each chapter, so that when you read it later, it will make sense. Exams are hard, but not tricky if you have taken the necessary time to understand the material. Read the book.

Professor Duncan is a kind and very knowledgeable. He is willing to help you do good in his class if you put in the effort. His homeworks are easy if you understand the material. Exams are hard because he is picky about the details when answering questions. Overall, as long as you actually care about this class you'll do well.

Dr. Duncan is a very smart sarcastic man, but he knows his stuff. Duncan likes for his students to succeed so he will be a hard ass, but he gives you the resources to hopefully understand the material. What I liked best about Duncan is that he tells you what material to PRACTICE, PRACTICE, and PRACTICE. Homework is a must do in this class.

Favourite professor I have ever had. Changed my major because he changed the bio game and made me fall in love with the subject. If I could have him for every class, I would.

Dr. Duncan is a genius. He knows what hes talking about. Use all the resources and do not get behind in this class. Use the handouts and practice quizzes!

Dr. Duncan is a genius! I felt super humbled to have him as my BIO professor. His classes are tough and he expects a lot out of you but it is worth it!

His class is great. You have to work hard but if you do the learning outcomes, watch his videos in canvas and read the textbook you should be fine. Definitely start studying for his tests two weeks in advance. He gives a "curve" on the first two tests and it definitely will help your grade. I would take his class again!

Dr. Duncans lectures are fast paced and can be confusing if you do not read ahead of time. He posts video lectures on canvas so you can watch them as many times as you need. The quiz questions are on the tests. 2 midterms and a final with occasional quizzes and homeworks. He explains things well if you focus hard.

Dr. Duncan was definitely a great lecturer. He was very clear about the things that would end up the exam. He did do a great job of teaching the material in depth. However, he was pretty disorganized, which made things sometimes difficult in a remote format. He also assigned long textbook readings that were never covered in class or on the exam.

Dr. Duncans lectures are in depth and fast paced. The class is very manageable as long as you dont put off work and keep up with the reading.
