Good Professor. Fairly detailed, and really enjoys what he was teaching. Sometimes goes off on tangents, but in general is very committed to the class. For the fact that the class was quite boring, many students still attended the lectures.

Nice guy, enthusiastic about the material, did his best to make it fun, don't need the book for this course, his online notes are really helpful

Lectures are kinda boring as he reads from the slides. He was helpful while doing the actual project, though.

A very nice person and an amazing professor ! There is so much we can learn from him and he really cares about the students .

A good professor, and very motivated to retain information towards your professional practice.

Lots of reading, watching videos and writing notes in a logbook over the semester to prepare for the final exam.

Good prof, show up for classes,take notes and you'll get an A

I really liked Denis. A really good teacher of electrical engineering. Expected you to understand the basics immediately though, but explained harder stuff very thoroughly, with lots of examples. Also the final and midterm were exactly like the previous years' finals and midterms.

Really great prof who is willing to help you out. The final lab was hard but we definitely learned a lit. Denis would even come by late in the afternoon to the lab to help us out. Chill dude.

Onen is a good professor. He is usually available outside of class and cares a lot. This leads me to believe he has a "it's for your own good" mentality when it comes to work load. This course took up most of my time this semester. I learned tons, but it affected my grades in other courses. Get ready for a lot of work.

Dr Onen was one of two instructors for 453, which was one of the best courses I every took in university. Dr Onen brings so much experience and inspiration to the classroom and he is always there to listen and help, and talk engineering. This course is meant for those who are genuinely interested in programming. It's not a dine and dash.

Denis is so far the best professor Ive had in engineering. Hes thoughtful and caring. Unlike many profs that read off the slides; Denis interacts with students and cares about their success.

If you thought ENEL 453 was demanding in workload, 400 takes this up a level. Although it was great we got to choose what project to work with with throughout the semester, the amount of deliverables for this was ridiculous. Denis is an awesome person with tons of useful advice as a professional engineer but is a savage when it comes to marking...

I learned a lot in this course, albeit on your own. But it was way tooo much work. Make sure you get a good group because you don't want to carry deadbeats, course is hard as is. Also get your circuit fabricate ASAP. Denis tried helping us but it was high level stuff instead of low level details. For that the techs are a GEM.

Kind prof who knows and understands his material very well. The course is very lab heavy with lots of group projects. The group projects are definitely time consuming, but the midterms are very fair.

Super nice guy. Very approachable. The labs in ENEL 453 are very intense but Denis will provide great feedback.

Denis is a prof where if you care about the material he cares about you. He will go to the ends of the earth to make sure you understand, but he expects you to put in the effort. Denis means it when he asks for feedback, and he takes it to heart. If you went into engineering because you have a real passion, Denis will be your favorite prof

Great class and great professor. Labs require work, but I also found them really rewarding. He knows his stuff about the industry, and formats his class in such a way that it seems to reflect important principles for future careers. One of the better classes I've taken yet.

Onen is a great professor, exams are very straightforward if you show up to class and do the labs. Labs take some time but are extremely worthwhile and are a great way to understand the material even better. Very caring and always willing to give students help in lab and outside of labs.

Overall a really great professor who cares to see that students understand the material he's teaching and is truly passionate about electrical engineering.

hes a very good passionate professor , who loves electricity more than anything.....

I don't know about upper year ENEL classes but for ENGG 225, Denis Onen is a good professor. He explains concepts well, and is very approachable. Most importantly, he cares a lot about his students and he's really passionate about what he's teaching.

Not your typical engineering class, includes a lot of writing (about 100 pages in a notebook, 2 reports of 10 and 20 pages each). The marking for the reports is not quite lenient, and the final is easy to do well on if you take good notes and do past exams. Start the logbook early. Denis does his best to answer questions and is a good prof.

I don't know why onen gets low ratings, because in my experience for ENGG 225, he was an amazing prof. He really tries to be accommodating the the students, and will make online lectures instead of in-person when he knows our schedules are really busy. He is very approachable and smart too. Great prof.

I heard he is a really bad prof for ENEL courses, but for ENGG 225 he was really good and cared about his students. He also gives you insight on what the difficulty is for the midterm and the final and I found that really helpful as well. Would recommend him for ENGG 225 (but again, I don't know how he teaches other courses)

very good prof.

I don't know why he has bad reviews he is amazing!! His lectures are so helpful especially the ones on youtube and you can clearly see he is passionate about circuits. Explains concepts in details and in a clear informative way. He cares about students that work hard and will try to help students that are struggling.

Amazing prof. Feels like a dad when you go talk to him. 100% recommend.

He's a great prof for engg 225, and tbh all the profs for 225 are amazing. He cares for you and is very passionate about the field. He prioritizes labs and shows some pretty cool real-world applications. A really great prof.

He's a very enthusiastic professor that clearly wants his students to succeed. Personally I think he goes above and beyond when trying to accommodate his students and their learning experience. Very passionate about the topic he is teaching, has great notes, and explains concepts with clarity. He made this class a breeze to learn.

inspirational, he is the reason why I chose electrical engg

Denis is an incredibly insightful instructor who cares about his students. With a contemporary teaching strategy, delivers engineering education in a hands on manner - one that isn't emphasized enough. He values hard work and effort, and makes himself available if there are inquiries but def a prof cares about student growth. Reco 100000%!

Dr. Onen is a gem. He cares so much about his students and their learning. He values fairness and good work so you can have confidence that he won't be giving anyone a unfair advantage. Sometimes he seems blunt, but ultimately he just wants you to learn. He's also always willing to chat and give advice about engineering or life. Highly recommend.

He is a solid professor but some of the things which were not well done in the course were that lectures stopped around Week 7 of the semester so the class didn't even receive all content due to the fact it's being run first time except his lectures for this course to get better. As of right now not well presented but a nice professor.

Amazing Prof

Onen the GOAT, he's amazing! He's an incredibly caring prof who is passionate about what he's doing and is great at lecturing. Only issue I have with him is that he stutters quite a bit during lecture, however, in the grand scheme of things it ain't too bad.

Really cares about his students and is very easy to get a hold of. Very helpful and accessible outside of class as well.

Amazing prof, cares a lot about his students and his lectures are really clear. He knows what he's doing and it's clear that he's very passionate about it too.

He is by far the friendliest prof I have ever had. He did a lecture summary with examples at the beginning of each ALS session which helped a lot. He also tried his best in explaining any difficult concepts. Even though he's not the course coordinator, he always kept his students up to date with any information he got from other ENGG225 professors.

The atmosphere in this class is always so cheerful and fun. Onen loves making jokes, and he's amazing at encouraging his students with their progress. He'd visit our block outside of class time just to see if we need any assistance with our projects. He even went to the Makerspace on the weekend to test the equipment for some groups.

I enjoyed taking ENEL 453 and 400 with Onen. A knowledgeable professor that is available to help students outside of class regarding course material, or internship advice. Although there were some weird quirks in his classes, like an 8-page handwritten final for ENEL 400, he will reward students who show effort & engagement. Is also pretty funny.

nice guy

rlly good prof who cares about student learning, his lecture videos were the best of all the other 225 profs in my opinion, he also gives little review lectures with content from weekly videos which is nice

The only teacher that matches the teaching experience back in Nigeria.

Dr Onen has very high standards and expectations for the students in this class. He expects his students to try their absolute best in this class. It is an engineering ethics class, and it is understandable why it may not be the easiest A. Dr Onen inspires you to work hard for the grade you want to have. Amazing prof!

Dr Onen is the most caring professor at University of Calgary. He is a tough but fair grader. He has high but very reasonable expectations. Just follow his rubric and you will do great. He is a truly amazing prof!

Denis was probably my favorite professor in all of first year. He is the friendliest professor I've met so far and takes the initiative and time to reach out to us out of class time. While his lectures aren't the greatest as he tends to go on tangents quite often, he still keeps them entertaining and often chats with us during work sessions.

I was very lucky to have Denis for the second term in a row and he was just as great. While working on our projects, he would go out of his way to talk to us at the Makerspace and help us with any problems we faced. This course is a GPA booster and Denis definitely helps with that.

All the assignments, rubrics for assignments, and materials needed to do the assignments were given at the beginning of the course. If you didn't put them off and did them as the semester went, the course was very manageable and easy. If you fell behind RIP. The final video was graded tough, but it was hard to fit in all material given time.

He is a really good professor and there is no denial in that. Most of his video on youtube has helped me tremendously before exam and final. Nevertheless, he might be a little bit peculiar occasionally and the way you represents yourself in front of him is quite important. He also endorses his favorite students so try to approach him and be nice.

Denis Onen is maybe the only professor who actually cares about his students. Although the class is quite difficult, there is much to love about Dr.Onen.

Great course. Although relatively straightforward in content, his lectures are clear and promote a better understanding of the course. He makes time to talk to all his students which I have enjoyed. Sold me on electrical eng.

Dr. Onen is the only first year prof i have had who makes an effort. He connects with students on a personal level, and is understanding. he is also clear and concise with his teaching. His class is very tough, but he is fair in his grading and always willing to help his students.

Very nice and funny. Enjoyed his lectures and had fun in the labs. The only good professor I've had for first year engg so far.

good prof not too much to say other than that

I'm not sure why there are so many negative reviews. The workload is heavy, but Onen is a fantastic professor and cares a lot. He is always available to help, and he identified the problems we had and provided a solution every time. I 100% would take a class from him again.

For 453 this year Onen was actually really good. Fair midterm and Final. The labs were a good difficulty. The final project was tough and time consuming but Onen was very helpful and stayed at school on multiple occasions to help students out. This class was a nice into to HDL programming but by no means makes you a pro.

My all time favorite prof. Clearly cares about his students and puts in the work for you to do well. He was a bit behind in his course content throughout the semester but only because he made sure everyone understood everything. Made this class super easy with all his support!

I do not understand how he has a 2.9, he is such a great professor and answers all questions with detail.

Class is a lot of work but Dr Onen is one of the most caring profs at the school. He'll go around and sit with each group to chat about his career if your interested or give you good feedback on ideas or issues. Just hope your team is good because it is a grind.

Best prof on campus. He'll take extra time to make sure you're understanding his class. I've probably spent HOURS outside of class asking him questions. People who gave him a 1 most likely skipped his classes. He might be behind sometimes but he's not hiding that. He's only behind to make sure you understand everything perfectly. THE GOAT
