absolutely love this guy!
I concur with the previous review "Obviously intelligent guy, but he made me despise chemistry now. The class is very boring after the first marking period."
Hands down the best teacher I've ever had
He's a good teacher but I think he sort of looks down a bit on students who don't understand as some of the other students.I think he misunderstands confusion in a student for a lack of trying. I don't think he means to though. He tries to help. He's a nice guy
Obviously intelligent guy, but he made me despise chemistry now. The class is very boring after the first marking period.
boring guy and boring class.
EXCELLENT teacher. Great person. Easy class but can be boring at times. Lots of busy work. Hes a great teacher. Just pay attention in class and its easy af. He's great at teaching, very clear and very knowledgeable.
Dr. Heffner is the epitome of a teacher. He makes sure to go over everything and has a well-defined agenda that students follow every class. He is very good at explaining concepts in detail and preparing handouts that reinforce material that he teaches. It is obvious that he knows what he is talking about. His class is the only class in which I am more than willing to do assigned homework. Really nice guy, too.
If every teacher were like Dr. Heffner, humanity would be 1000 years ahead of where it is today. His class can get a little boring, but his subtle sense of humor makes it a lot more enjoyable.
Really good teacher by making Chemistry fun and easy to understand. He breaks up his flat tone by sometimes having EXTREME BURSTS OF ENERGY out of nowhere, which is pretty amusing. He's pretty picky on short responses, but it is designed to help you understand the material completely. Just make sure to show your work and use correct sig figs!
His labs are super hard and his tests are tricky, but he is undoubtedly the best teacher I've ever had. You will leave his class with confidence in what you've learned and really prepares you for ap chem if you choose to take it.
Really great and organized teacher. Supplements his teaching with easy to understand worksheets that he makes himself.
One of the best teachers at Charter for sure. He knows his subject and teaches it well, and plus is just a super swell guy.
Awesome teacher but his labs are so hard!
He is a little rude one on one but overall a fantastic teacher if you pay close attention and do your hw
Excellent teacher and as long as you pay attention you should do fine
Dr. Heffner is a phenomenal teacher. His class may not be easy, and his tests are next to impossible, but he explains things really well and knows all there is to know about chemistry.
His style of teaching can be confusing but I guess he's alright
He teaches all concepts and his worksheets should help you understand most of the class. His tests are easy if you studied for at least 2 hours (counting homework). He is a bit bad one-on-one but you should be good with the class overall (Chem)
He is a really nice guy. He is very willing to help people if they don't understand the material, and he is actually very funny.
Great teacher. Moves a little fast, but teaches wonderfully.
He was okay at teaching. He never really involved the class all that often, he just talked and talked and talked forever....really boring teacher.
I love this guy! He's incredibly approachable, nice & quirky & the class is a breeze. There's hardly any real work involved & he teaches the material really well.
I had him for Chemistry. He incorporates humor into his lessons and give a good bit of homework. Sometimes his labs are a bit unclear, but he listens to students' questions and tries to help.
DHeff is a wonderful person and teacher, and always makes class fun. However, he does tend to move a little faster than most students are comfortable with. Still, overall a wonderful teacher.
He's a cool guy and a much better teacher than Vasta. He makes things easy to understand.
He is the best teacher I have had at Charter. I love the way he teaches and he goes over everything :) Awesome class!
Great teacher. Had him for Intro to Chem and Regular Chem and he built a strong foundation in basics. Funny guy and teaches the material in his own way.
Not sure about intro chem, but reg chem he speeds through so much material even when half the class is having trouble. He takes off points for such stupid and frustrating reasons on some tests but all labs, and is unwilling to help out on confusing labs. His class is extremely boring, also.
Best teacher at charter, had him for intro and regular chem and now my sister asks me for help with her college chem homework and i know how to do it all. He makes chemistry easy and entertaining
He was okay in intro to chem, but in regualr chem there's so much moreinfo and he does NOT teach it well. Also, he's lying when he tells your class he'll push back the quiz if the class is having trouble.
=D Very laid back- teaches material well. I especially enjoyed him in Intro to Physics. Looking forward to Intro to Chem! ^-^V
I loved Intro Chem, one of my favorite classes freshman year. He really taught the material well, and i thoroughly enjoyed all projects and labs done in the class.
heffner was cool in chem, and he was a pretty good fermi questions coach
Dr. Heffner is one of the most interesting teachers at Charter. He explains topics effectively, and he is fair. All teachers should be a little more like Dr. Heffner.
Loved Intro Chem with him. Is very good at what he does. His class was very enjoyable and a good introduction to science at Charter.
Amazing teacher, especially after having Toner. I like the way he talks. He's funny. Chemistry is a really easy class, though.
poor guy.. students abuse him but hes a very intelligent guy and he does try hard 2 be interesting/helpful
His voice is sleep inducing but if you bother to listen, i really liked his style of teaching. It made a lot of sense to me.
He is so boring. Be prepared to pretty much teach yourself or get caught up on your sleep.
He is soo boring. This lectures aren't very clear and he doesn't explain the material.
