Comment:

Prof Langer was great! I liked him sooo much more than Chris Butler. Langer builds his course on understanding the material, instead of just memorizing. Homework was online and helpful for learning. Weekly quizzes helped keep me on my toes and study weekly. Overall, great professor, great person, and passionate about what he does! Would recommend

Comment:

Relatively dry, but his passion for the subject is obvious and infectious and makes up for his lack of charisma. His tests and quizzes are very fair and straight forward, although the material can be challenging. His weekly homework can be difficult but never long. Unfortunately, not very accessible outside of class. Overall, a solid choice.

Comment:

His lectures are not very interesting, but he does his best to answer all questions addressed to him. He gives partial credit, and a lot of it, proving he values more than just the answer. His grading criteria is clear for the most part. The lectures are incredibly boring as time goes on, but for those who pay attention, it is helpful.

Comment:

Really knows what he's talking about. Quizzes are not on a regular schedule but expect 1 per week; he'll let you know when it is in advance most of the time. Lectures are CRITICAL to passing quizzes and tests. Don't skip class! Really! Otherwise coursework is pretty standard, but quizzes and tests are same things you do in class. Not much reading.

Homework is hard but solutions are promptly posted. Quizzes and test problems almost directly off of the HW. Attendance is not necessary. Study the HW problems before every assessment and you'll get an A (except for the final, which is extremely difficult and theoretical, but also curved heavily).

Comment:

Alot of the time the homework is next to impossible to complete, especially at the end of the semester when the topics get really theoretical and his lectures don't match up with the homework. Beware and get help asap because the final mostly contains the end-of-semester topics.

Does not like to answer emails, assigns one to two homework assignments per class that he makes up. I went to him in office hours and he was confused as to why I couldn't figure the answers out myself. Would not do examples in class only does definitions would not take

Comment:

Homework started off difficult because of heavy mathematica usage. As the semester went along, he started to grade the homework more easily. Pop quizzes also became easier as semester went along, eventually becoming group quizzes. Tests weren't too hard if you read through the book and looked at homework and quiz problems. Final project was alright

His class has to be my favorite this semester. He loves mathematics and he lets you know it. He has us present homework questions to the class which has really helped my public speaking. His feedback on the homework is incredibly useful and when he likes your work he lets you know it (and when he doesn't he'll tell you how to improve). I r8 88 m8.

Comment:

This past semester Langer has completely changed his teaching method. Instead of curving up like in past semesters, he curved downwards, dropping everyone's grade up to 6%. You're on your own for this semester if you have him. He teaches everything very abstractly and goes off on tangents - so self learn.

Professor Langer was overall pretty good. Not the most thrilling class, but he was very clear in explaining the material and he was always really nice. Barely ever used the book and did pretty well completely from the lecture notes.

Comment:

Great professor. Explains things well and offers lots of examples. Goes over homework in class if he isn't too far behind and everyone in the class didn't get the answers. Tests are based almost completely off of the practice review so you know what to expect on the test.

Comment:

Langer is a great calc teacher. Notes are fairly clear and directly help with homework. Can go off on tangents on how certain theorems or equations are derived but that's just his passion for teaching. Tests are solely based off the homework and review packet, so if you study those hard, expect a good grade.

Comment:

Langer is extremely clear in his lectures, and he offers a lot of examples in class that really help you understand the material. I highly recommend going to class not only because he takes attendance daily, but also because the book is of little help. Be sure to keep the material in mind because exams are very spread out.

Comment:

I won't agree with anyone who says that going to class is essential. Lectures are dry and unhelpful, as he goes straight from the book. I didn't really care for his teaching style. I did well in the class despite not going to lecture often.

Comment:

Langer is a great math professor. He is a great lecturer, and even though he does not take attendance, going to class is essential. He LOVES Mathematica, and required us to use it in every assignment. It makes the homework take a very long time, but once you get the hang of it, it is actually nice to know how to use.

Comment:

He's understandable if you pay attention constantly in class. Doing so is recommended because the textbook doesn't help very much for either the homework or the tests. That being said, you can learn a lot of math if you do take the time to get something out of this class.
