Reviews of professor Keith Osai

Rating: 1.0/5, difficulty: 5.0/5
Professor Osai is the worst. I hated this class. He never lectured at all. He had us split into groups. Read sections of the textbook then share. It felt like he was always unprepared. Most pointless thing. I learned nothing. Whatever you do avoid taking a class from this awful teacher. He gives poor instructions also.

Dr. Osai is very kind and knowledgeable, but I did not love his class.  The lectures were long and unengaging and could have pertained to the text a little more. Felt like he went off on tangents and did cover important information needed for tests/quizzes. Reading the textbook and taking your own notes is your best bet.

The least helpful professor I have ever had. Does not communicate clearly or effectively and fails to respond to questions in an understandable manner. Doesn't seem to know how to work Canvas. Weird expectations and processes for volunteer work that he does not explain.

He is a great person and very kind but wow he struggles with an online class. HUGE semester group project with very little time in class. Tons of reading for this class. Tends to ramble during lectures. Instructions for assignments can be confusing and vague. I learned a lot, but do not take his classes online.

Osai doesn't really 'teach' and instead assigns chapters to groups in class and then we all tell the other groups about the chapter we read. He got mad when we didn't come to class in person despite offering zoom for every class. There's a big group project, exams, and 2 papers based on parenting books from the 90s. 
He's fine, not bad not great.

This class was really slow. The lectures in class were helpful, but could have been done a lot faster than they were. So, slow. A few big assignments, but really easy to keep up with. If needing an easy class, go for this.

He is a really nice professor. You have to read the textbook and do the quizzes before we can get to learn the stuffs that are on the quizzes with him. However, they are open-book, and he gives you two attempts. The tests are not open-book, but you will do find if you take notes, and study. The textbook is also free! (It is an e-book)
