Pretty good teacher.

He was a pretty good teacher. Liked to teacher this class. Friendly and easy to talk to. Online quizzes aren't hard. Tests are straight forward. Always had help sessions if you needed them. Got excited sometimes when doing experiments in class.

I enjoyed his class, but we need to be able to have a page worth of notes for tests just like some of the other chem teachers! Just a hint!

Great teacher!!

He is a really good teacher. He loves chemistry and wants everyone to love it too! He is so incredibly helpful with office hours and help sessions-he truely wants everyone to succeed. His class is not difficult if you do the homework and put forth a little effort. The tests are pretty straight forwar. great sense of humor- i loved this class!

This class is very easy as long as you take notes and come to class the majority of the time. Most of the test questions are pretty easy. The class can be pretty boring at times, but the professor is very nice. He cares about what he is teaching and wants others to care too.

VERY helpful. Has help sessions every Tues and will answer any questions during class. Tests aren't hard if you study. Quizzes every week online but they're sooooo easy.

Great teacher! Dr. Hamaker was great at making sure we understood what he was talking about and at explaining things. He's always there to help you, whether it be Tuesdays at his help sessions or if you need to make an appointment. Take time to go to his office hours!!!! if he knows who you are and knows that you care,you will do better!

go to class and you will do fine, the test aren't hard and the final is easy

Hard class if you do not have a chemistry background, but he was very helpful in understanding at Tuesday study sessions, and you could also see him during office hours if you don't understand everything. Lots of work, but pays off in the end.

Good professor. Great person. I could definitely see myself friends with this guy in the future. You'll need to work your butt off in his class, but you'll get sooo much out of it.

Good teacher and fair although his class is hard. He gives you practice problems at the beginning of each chapter. they are def worth your time.

This class is no joke. It's going to be hard if you don't take the time to study. Hamaker is a great teacher though. He is always willing to help you and he has reviews once a week where you can ask anything you want.

Great teacher!! Very helpful. Lots of points in this class. Drops one test and two online quizes. Do the work in the book (optional) and you'll do great on the tests!!!

He is a good teacher for the most part. He teaches up to the exam, so make sure you do the suggested problems in the book. I pretty much learned I had to teach myself how to do the majority of the stuff he teaches. Go to tutoring and stay for review sessions he holds once a week.

HIGHLY RECOMMENDED. Take him, trust me, you won't be disappointed.

He was a great teacher. Test are easy. Tutoring helps.

Good teacher. Explains everything clearly and gives plenty of examples to help you better understand it. Theres a decent amount of points.Theres an exam every other Thurs and a webquiz the weeks theres not an exam. May sound bad but not really. Kinda nice because then there isnt as much material on the exams.

If you have none or very little chem background prior to this class, then it could be quite difficult. However if you've taken a lot of chem, then the class will be a breeze. Do not miss lecture. He teaches for the entire full 50 minutes every lecture. he uses excellent examples. I recommend buying the booklet of his past exams, it's very helpful.

Mr. Hamaker is a WONDERFUL teacher.. he teaches everything in a clear and concise way and if you don't understand something, he is more than happy yo clarify. Although this class is tough, the exams are layed out in a good way. you have 7 exams that only cover 2 chapters each. It sounds awful having 7 exams but it is better than 4 exams!

He is a great professor!

Dr. Hamaker makes Chemistry very interesting and easy to understand. The "molecule of the week"'s are always fun and are a good way of understanding how chemistry relates with everyday products. Buy his booklet of his past exams, saved my life!

Dr. Hamaker is one of the best teachers I have ever had in my life. He genuinely wants to help you learn the material. I went into this class thinking I would fail and I've ended up with an A, because Hamaker is so helpful. You have to work hard, but that's expected for a chem class. I highly recommend going to his review sessions.

Wonderful teacher! Easy to understand, and oddly attractive! Very helpful in and outside of class.

For a gen ed course, Hamaker makes this course WAY more difficult than what it should be. If this class was based on his exams, probably 80% of the class wouldn't pass. He expects everyone in his class to automatically be a Chem or Pre-med major, when a lot of people aren't.

What? Best professor at ISU? Doesn't do any chemical experiments during class. It's mostly him yelling in a boring monotone voice, reading from his notes, writing on the white board, the whole time. He doesn't stop to let anything sink in, either. So boring. Not 4 year college material. I expected MUCH more, especially from a 4 year college.

This class is in no way easy. You will have to work hard, but Hamaker is probably the best professor I have had while at ISU. This class is not supposed to be easy. I went to tutoring at the visor center the first day. Dr. Hamaker explains everything so clearly!

140 is suppose to cover the same material as the first semester of AP Chemistry, which is hard. Those who expect class this to be easy are in for a hurting, as chemistry is a very difficult field of study. Dr. Hamaker does a very good job explaining it. Go to class, take notes, read the book, and participate in the labs and you'll do fine.

GO TO CLASS, his tests are difficult and will not let you use a graphing calculator, so be prepared to buy a nongraphing calculator.

Ive taken chem 140 twice and mr. hamaker tought the class way better than my previous instructor. I also had him for chem 110 and hes definitely one of my favorite teachers!

I had Hamaker for Chemistry 140. If you have never taken Chemistry I would not recommend jumping into this class. He is a brilliant man but he teaches above students thinking capacity and flies through EVERYTHING. It is a hard class. You will have to get tutors and seek extra help but he is a pretty cool guy.

GREAT teacher! Must go to class - he Does throw a lot at you all at once, but you REALLY have to have the time to devote to studying for this class. He has help sessions and he is awesome in explaining things- Very SMART guy!

Clear teacher, will always answer questions if asked and always attempts to make time for students. Expects a lot, but is completely passable if you are willing to put time and effort into the class.

Fun to listen to and clear in message. If you have any trouble, email him and he will provide a useful response the same day! He tries to make sure the whole class understands before moving on, and really seems to love his job while taking it seriously. Definitely recommend taking his class!

I am a chemistry major. I had taken two years of chem in highschool. This class is not a class for someone who hasn't had a chem class before. It's not difficult if you study and there are we quizzes and lab grades that act as a grade booster. He is helpful but sometimes quick to put the info out there. Reallllly loves chemistry though. Good guy

Very good prof for a very hard class. Don't expect to skate through this course as the material is very challenging. Hamaker goes through his lectures very quickly. Definatly go to class and go to his review sessions or tutor sessions. An A is unlikely but a B is possible with alot of hard work.

Great professor, anyone who says he wasn't is just upset because they probably didn't go to class and probably didn't get a good grade because of it. If you go to class and do the suggested book problems, you'll definitely get an A.

Dr. Hamaker really knows his stuff. Tough course, but if you go to class and do the homework you should be good. Tests are tough but reasonable, and lectures are very quick and un-thorough.

He is a really nice professor even though you do not have to go to class you get clicker points that end up being beneficial to your grade. Also try to do good in his class because he does curve his overall grade sometimes I was at a D without the curve but with the curve I got a C Hard class your going to have to study, do the practice problems

1. go to class even though this class is not mandatory he gives out clicker points that do count for a grade. 2. read the book and do the practice problems it will help. 3. Take notes and pay attention in class. 4. study hard and you can get a hard earned A or mostly likely a B

He tries to keep class entertaining, and usually does. He's a funny guy. He has a lot of tests, but drops the lowest one which is nice. It is a generally easy class.

If you are ever uncertain on any material, email him right away! I spent weeks looking for a way to figure out some content and he cleared it up in a two-sentence email! Not only that, he responded only a couple of hours after I sent it. It's clear he loves what he does and he really knows his stuff. Great for exploring Chem or a gen ed.

At the start of the year seemed really cool and helpful in lecture and then seemed annoyed whenever I would come to his office. Acted like I was bothering him even when I would email him ahead of time to make sure it was okay to come. The tests are tough and the questions are worth so many points. TOUGH CLASS

Hamaker is a great professor. He teaches the material clearly and efficiently. I wouldn't want any other professor for lecture.

He writes things down on the board and then starts talking right away before students have the chance to write it themselves. He will go into good detail and he answers questions well, so make sure you ask. Lots of difficult questions and trick questions on exams.

He is really nice when you come up to him for questions and he accepts feedback from his students. Make sure to come to class every day because the clicker points saved me. He also gives extra points here and there when he sees students struggling.

Dr. Hamaker makes chemistry seem interesting! You do need the book in order to complete some of the labs, but unless you need extra help (like reading or practice problems) you most likely won't use it much. If I were to take the course again I wouldn't buy the book and would use the reference textbook in the library. Overall though, a fun class!

Had professor Hamaker as my lab instructor for Chem 140 and I wish he was the lecture instructer, thats how good he was. He cares about everyones growth in the subject of chemistry

Hamaker is a great guy. A lot of people say 140 sucks, which is half true i guess. It sucks because it's very challenging, but if you go to class, study hard, and most importantly go see Hamaker for help when you can, you'll surely pass. Hamaker is always happy to help and has been so chipper and friendly to me every time I've asked him for help.

Dr. Hamaker is actually a great instructor! It's a little strange because instead of using powerpoints, he will write the notes on the whiteboard. For each chapter, Dr. Hamaker will give recommended questions (not for a grade) and doing those help a lot on the weekly online quizzes and the exams. I struggled bc I don't like chem, but he's great.

Dr. Hamaker was great to have in class, but Chem 140 is just really hard! Grading is hard and you definitely can't depend on partial credit in that class because every TA grades differently. Go to lab and put the time in and you should pass.

You don't need the book unless you are planning to do extra problems out of it. The way he gives notes in his lectures is extremely helpful: he writes everything out on the whiteboard. He is super caring about his students and is available outside of class. Great professor

Hamaker is the best lecturer we have. His notes on the board are everything since they show you exactly how he wants you to do problems. If you're not a Chem Major join tutoring, its extremely helpful. If you are a Chem Major, sign up anyways, the more ways you hear something the better you understand it. Just go to class and take notes, not hard

GREAT guy! Had him for CHE140 and 141 and I highly recommend. He is very straightforward with material and his expectations, so there is little room for misinterpretation. Genuinely cares about students learning and is very helpful outside of class. He does challenge students, but nothing too unreasonable. If you get the chance, take him!

INCREDIBLE PROFESSOR, great guy always available in office hours. Highly recommend taking his course, and going to his office hours he is very approachable and wants you to succeed.

He is a very good professor and writes all you need to know on the white board. If you listen to what he is saying/pay attention in class, that's what's on the test. The end of chapter questions are not required, but very helpful. Does require previous chem knowledge, but a few tutor sessions will help with that. He is always available to help.

Dr. Hamaker is a great professor! He cares about his students and always answers questions. Great teaching style - he uses the white boards. You NEED to go to class to do well. I also suggest doing end of chapter problems. The exam questions are based on class work and occasionally an end of chapter problem. I also suggest doing Visor tutoring.

I had Dr. Hamaker for 140 and 141. I really appreciated him as a professor for 141. It became clear to me how much he cared for his students & their learning. You need to go to class. Every point counts equally for grading so do clicker points, get 7s on all quizzes, try in lab, and study for exams and you will be fine. Great teaching style too!

Hamaker is probably the best 140 and 141 professor at ISU. The class definitely wasn't easy, but if you start studying or at least looking over the notes a week before the test you should be fine. People who say the exams look nothing like what we learned in lecture probably just weren't going or weren't putting in the work.

Best Chem professor! You must go to lecture because he rarely uses slides. If you take the quizzes seriously and make sure you understand what's going on during lecture you will be fine! Also study from the 141 tests the previous semester because he uses the same questions with different numbers. Very straight forward and kind guy!

He's a really great guy. I really liked his teaching style- he teaches by writing on the whiteboard so you can't miss class. He gives an "exit quiz" usually once a week which is basically his way of taking attendance. He's super nice and very helpful one-on-one. But you gotta work for it. Do the homework and know how to do problems from your notes.

Dr. Hamaker is a really nice guy and I enjoyed his class even though it was hard. You definitely need to go to lecture because you could be tested on anything. He gives pop quizzes (like once a week), online homework and weekly quizzes. The exams are REALLY hard but it's still possible to do well in the class even if you have low exam scores.

Great professor. You need to go to class and study, but he is always willing to help. The chem101 homework website is super helpful and I recommend doing the practice problems before exams. Look over the notes before it's too late and be sure to understand from the start. Final exam questions are all questions from previous exams with different #s

Professor Hamaker has been one of my favorite professors at ISU so far. Although some lectures may be difficult to understand, he puts a lot of passion behind his teaching. I've always hated chemistry, but because of Hamaker's teaching style, I always anticipated lectures. I recommend not skipping any lectures, he does unexpected E.C points.

Was very lecture intensive, but the is good at lecturing and is very clear about what information you will and will not be tested on. Overall great professor for the material he taught .

Prof. Hamaker was incredibly passionate about the material he was teaching and really cares about helping students. He does all the lectures on the whiteboard and doesn't post notes, however, so I wouldn't recommend skipping lecture otherwise you will be behind.

He has an old school style of teaching and is good at answering questions that come up during lecture. Exams are hard and don't have a lot of multiple choice. Study off of the exams for the final as it's just slightly reworded questions from the exams. The HW and online quizzes will pad your grade.

Dr. Hamaker was one of the best professors I've had. Lecture material is not posted online, so show up and take good notes. His lectures are very clear and he does plenty of examples during class. He is also very willing to answer questions and really wants his students to succeed. Exams are not too bad as long as you take good notes.

I had Dr. Hamaker as my 251 lab instructor and he was a great professor for this. He always answered questions and made sure we knew what we were doing. I also met with him during his office hours and he always makes time for his students and is very approachable. He is very organized and professional.10/10 would recommend him for this lab section.

Very good lectures. Explanations made sense and helped a lot on understanding the material. Aktiv chem helps prepare for exams. Final takes questions from old exams so it is VERY easy to study for.

Dr. Hamaker is a good professor and person overall. He's very nice to talk to about anything really and is always helpful with questions. The exams aren't very much like the homework on Aktiv Chemistry, but he gives examples in lecture. The final also used the exact questions from the previous exams so it was easy to study for.

Dr. Hamaker is an excellent professor who really cares about his students! He is so kind in his office hours, and really wants you to understand the material. Go to office hours to get to know him better too! The class was tricky at times, but Dr. Hamaker is clear about what is on the test!

You need to go to lecture. He is super nice if you talk to him. He answers questions and then makes sure that he answered your question. Tests are hard but several point grab opportunities, so the tests don't tank your grade. He is very passionate about his work, and you can tell in lecture. Book is online and not needed.

The class material was difficult but nothing unbearable if you put the work in. His tests are pretty difficult but if you use the online learning program to study and go to class and take good notes you should be fine. Attendance is not mandatory but it helps you understand the material so much better than just copying the notes down.

A lot of people didn't like Dr. Hamaker because the class is difficult but he's a great professor. Tests are hard, so you have to study but they're not impossible (I got an A on all). He's very personable and loves questions and was very easy to access outside class. Labs are every week for 3 hrs but they were interesting. Be ready to work hard.

I struggled with this course since I had some personal issues going on. His exams are difficult and he does give out online homework/quizzes which saved my grade. I started off doing horrible on the exams and did OK at the end. Overall, I was failing the class & he took into consideration of my improvement throughout the year at the end. So caring!

He was a very good professor and you could tell he was passionate in what he does. Tests are hard but if really prepared they are doable

Dr. Hamaker is by far my favorite professor at ISU in the chemistry department. He goes mostly off of his lecture notes so you can almost guarantee that's what the exams will look like. There was also a group research project that really helped with your grade if you do bad on exams. He really cares about the students and is there for you. 10/10.

I don't know what group of students wrongfully decided to give Dr. Hamaker 1.0 ratings. Lectures are easy to follow along, notes are easy to use when completing homework. Yes, there's a heavy load of homework, but exam questions are taken from homework and benefit you in preparing for exams. He's a sweet old man who loves to teach, great class!

The list of 1.0 ratings has to be a group of students who are failing. I wasnt going to give Hamaker a rating but seeing those 1s made me want to. if you go to class(and pay attention is the key), do the Aktiv homework, and ask questions in or outside of class when you're unsure of smtg this class is no problem. easy A or B. Hamaker is a great prof

Only time I've not been on the verge of failing a science class in my life. Amazing lecturer that challenges you fairly.

He was a good person, and he was a pretty good professor. He was very reachable outside of class and was kind. His lectures were a little all over the place.

He cares very much about his students. He is aware chemistry is not everyone's cup of tea but he understands the subject and how to teach it well. The homework doesn't count for much of the grade and there is a lot of it but if you don't do it you have no shot at passing. The tests are hard but the worst one gets dropped.

His lectures are really engaging, he takes his notes on the whiteboard so apart from getting notes from people in the class they're not posted on canvas or anything. He has a lot of things that count towards your grade which makes it easier to get a high grade. Just make sure to do everything that is graded and not miss any labs.

Dr. Hamaker was by far my favorite professor. He is really passionate about chemistry and it shows. He is very kind and is totally willing to help you! He doesn't use slides for lecture, but rather writes everything on the whiteboard. It's easy to get an A/pass if you do all the homework and quizzes which directly prepare you for the exams!

Lectures are engaging, but the tests are challenging. Using resources like Unstuckstudy alongside the free textbook helps prepare. Attendance is a must - Dr. Hamaker explains things clearly, and office hours are very helpful.

Dr. Hamaker is amazing, your grade is definitely worked for throughout the semester. Utilize office hours, he cares deeply for students and wants to see you succeed! Make sure you go to class and take notes! He is very clear what is tested on exams as well :)

Dr. Hamaker is a great professor. He is fast paced, but he is amazing at helping during office hours if needed. You do have to attend class because he is a white-board kind of teacher. There is also a good amount of homework but the test questions are pulled directly from the homework so if you work to understand the homework you will do well!

While attendance isn't mandatory, he only uses a whiteboard for lectures so no online material posted. Textbook is free, for every unit which is about 4 weeks there's 150 questions that the test is pulled from. If you understand lectures then the tests are fine. Best teacher and super understanding! highly recommend

This class was made so much better due to Dr. Hamaker, he cares about his students, the homework may seem like a lot up front, but that is due to it all being posted at the beginning and if you break it down it is about 50 problems a week 10 a weekday. Also attend lectures, don't skip (even if it's an 8AM!)

Biggest advice - ATTEND CLASS! He is a whiteboard and marker kinda prof. He moves fast, but will always stop for questions and encourages students to ask them. He is a very sweet man who is really passionate about chem. Go to office hours, get a tutor, pay attention in class. He gives partial credit on exams and the final is easy to study for!
