BUT IF HE HAS TO , HE CAN BE MEAN.. BUT THAT IS THE GOOD PART. IF YOU WANT TO BE IN IN HIS CLASS, ATTEND, IF NOT, THEN JUST LEAVE. GREAT PROF.MADE A DIFFERENCE FOR ME.

Great guy. His midterm and final exams were easy. He dropped online quizzes to bump up our marks. How nice is that. He should teach more Media Studies courses. He's much better than some Media profs that I've had in the past. If you do your work, then you will succeed in his class. We need more profs like John at GH. Thanks for a great semester!!!

John is one of my favourite prof 's at GH, he might discourage students that they won't do well, but he's probably one of the most intelligent profs the school offers. His exams are difficult, but if you follow the textbook, do your readings then you'll ace it. It's not a noting taking class, he'll open your mind and inspire you .

Not a note taking course, most of his PowerPoints are not easy to follow. He uses good examples to illustrate his points or what was on the slides.

He marks very random. He will make you do group presentations and give the group members who did not complete anything good marks and the members who did all of the work bad marks.

The manner in which the quiz questions are worded are frustrating to say the least. Many questions are Poorly worded which appear intent on tricking as opposed to testing course content.

Johns teaching methods differ a lot from most, however if you put in the work you'll get 100s. He can be rude, but if you talk to him one-on-one he is pretty understanding. If you've never had him before, he teaching methods can be confusing. He doesn't usually answer emails if its about the course, but if it is pertinent he answers.

I had irwin for Investigative Techniques and he was very confusing compared to other profs. He has unclear grading criteria and sets quiz time limits that are designed to fail students. If you care about your GPA, drop his class. He does not answer emails from students about coursework. He will make u fail!!!

Had Irwin for many classes from first through 4th year. If you pay attention and read the lectures/textbook, you will do well. Pay attention to instructions, he will not answer emails if you ask basic questions that can be found in breakdowns/syllabus or that were addressed in class. He doesn't take attendance, but the classes are important. 10/10!

I have a love/hate with this man Cons: test material is often not in readings/PowerPoints, participation matters, limited response to emails Pros: funny, engaging, interesting, and definitely not boring! He is one of the best professors I've had when it comes to lectures Tip: even if you fail his quizzes, you can easily pick up grades elsewhere :)

Irwin and his courses are completely unorganized. There is no structure, he often gives the same assignments different names or does not mention them at all, the drobox has duplicate assignments and due dates are wrong. There is no connection between assignments or his rambles and criminal justice whatsoever. He and students are equally confused.

Beware this guy has no idea what is going on and his quality of organization/course content is subpar to say the least. I honestly cannot begin to describe the lack of professionalism in this course and it's presentation. I was shocked that Guelph-Humber approved the course material let alone have him awards. Mind boggling.

I had him for JUST 4020. You need to be there for his classes every week, or else you can't get good grades. His quizzes and tests are difficult because they are usually questions he makes up, reason why I don't prepare for any of them. He has group presentations and does small group discussions. Overall, he's ok ish.

Irwin is a good person but his classes suffer from high expectations. For criminal offences he expects you to know the offences, sentencing and limitations of a lot of the offences. Participation is a must. He also makes ou go watch a court proceeding on your own time which was need to watch.

John Irwin is one of the most diverse professors I have ever had in my life. For one class, you may receive the highest mark you have ever gotten in any class. Then you have him again, and your average drops by a huge margin because of his insanely confusing algorithm. The best thing I would recommend for anyone is to always ask him if you are lost

Sure his marking can be confusing. But if you actually speak to him even once during the semester it makes all of the difference. He does things his own way but if you ACTUALLY go to classes consistently and engage with the lectures then you will absolutely succeed in his courses. I'd take him over reading off of powerpoints any day!

He's great lol. He's engaging, interesting & very easy-going. You need to attend because he teaches from memory and understanding rather than from reading off slides. He sometimes has high expectations for tests (they can be a little chaotic, but are usually online). But overall he's one of my favourite professors and I would recommend!

Though the assignment were very confusing most of the times. I was surprised that I did very well on the labs and individual assignments. The only thing I can say is, the professor was really hard to reach and doesn't respond back to emails, so if you don't understand it is best to rely on your peers.

He is amazing when it comes to accomodation and helping with problems. Easy marker and a lot of opportunities to increase your marks. Quizzes are a little tricky tho and he does not really respond to emails..

The most disorganized "professional" there is. It will take you until week 3 or 4 until you almost know what he expects from you in the course. His lectures are useless unless you enjoy listening to rambling.. I worked on a weekly discussion for a whole semester and it never got graded because "he forgot", a complete disrespect of my time.
