This guy sets up the class so that you cannot fail. The tests are straight forward, and you have many opportunities to get homework and quiz points.

helpful. really sarcastic and funny. total nerd, most examples revolve around star trek or sienfield. also, really likes sports and historical trivia, puts trivia questions all all the tests for EC. take his class. it is easy. even if you hate math, if you show up and try, you will do well...

Not quite sure what to say about him! He is strangeeee! Pretty easy tho!

I really like this class. Even though he yelled at me once in the middle of class and kinda embarassed me for no reason because he didn't under the question I was asking... BUT this class was the best math class I have taken at ASU. Easiest A ever....

Big D is the love of my life. I got an A in the class but I think I'm going to take it again just for D. My roomate and I both had him and it was fun for us to come home and share D stories. D if you are reading this I love you.

Oh by the way, he is very easy on the homework --- attend class sincerely!!!!

Very nice teacher, if you ask for help on a homework problem he is happy to go over it with you. He is a bit odd, but his personality makes what would be a boring math class a little more interesting. Webwork is pretty easy and I usually had enough time to complete it - between 9-15 problems assigned at a time.

He is a relitivly good professor, always goes over questions in detail, classes are all about the webwork questions so its pretty easy. tests are 20 questions over material discuses in the review class. Always responds promtly to emails and questions. he is a little strange but overal i recomend his class

He is a little strange, but is a good teacher. I am not very good at math, and I got a good grade. You just need to go to class and do the homework and you will be fine. Lots of EXTRA CREDIT! He really enjoys trivia, so he puts easy trivia questions on every test for extra credit. I would reccommend his class.

Mister D is awesome. Show up for class, do the work, and don't act like fools people! College yo! Mr. D will be in your corner the whole damn time. I loathe the maths, but his is seriously the best math class I've ever taken. I love you Mister D!

I am sure that I WILL NOT get an A on my calc 3 if I didn't take it with him. Calc 3 is hard and if your teacher decided to make it hard fro you, then you can say kiss bye to your A.

To begin with don't act like an idiot in his class or he will call you out on it...also do the homework they are easy points...he says attendance is mandatory but i went to class 2 out of the three days a week all semester and nothing happened...all in all he is a good teacher i would recommend him he is always there for help!

Really good teacher! Explains things well! Gives extra credit!

Absolutely the best Math professor I've had. He comes across as somewhat of a "goober," but his teaching style is highly comprehensible and he knows when to challenge you and when to give you a break.

To get an A: come to class (because he likes that)--do the homeowrk--study the test review sheets religiously because the tests are just like it. he is extremely helpful and very funny if you give him a chance. dont talk in class or use phones b/c he gets mad. i hate math aka calc but i got by with an A.

He's a really funny guy (in a goofy way), and he teaches Pre-Calc adequately. He's also more than willing to help you out, if you go to his office hours. I would recommend him.

Awesome professor, one of the best at ASU. Tests are just like the reviews. Definitely take him!

Funny, goofy guy that makes understanding this bs very easy. Makes class enjoyable. Gives a lot of partial credit on exams. Exams aren't too bad either.Take home quizzes worth almost 300 points total Go to class, study the review sheets, get an A. He is one of the best 210/211 teachers at asu.

so the first day iwanted to kill myself by the thought of having to see him 3 hours a week. he came across as the goofyest teacher ive ever had. but when we started learning, he actually is a decent teacher. he teaches pretty clearly but he makes jumps through equations without showing them. not the best teacher ive ever had. but he's up there

Mr. D is awesome, he does plenty of examples in class, and will to go back over anything if you don't understand. Told the class NOT to buy the book. Quizzes and homework help to bring up grades, and tests are pretty straightforward. Pretty goofy but extremely helpful.

Mr. D is a great teacher. He does move a little fast but is always helpful when you ask questions. He's really funny too, and seems like a gambler. Thanks Mr. D!

Mr. D is great. He knows math and explains calculus concepts quite well. I had never been a great math student but he kept my interest. He is pretty funny and I can guarantee you'll laugh at least once during class at his antics. Also, he is extremely helpful during office hours. If you're having trouble go to them. Superb teacher.

Best Professor ever when it comes to Math! Made math fun, tests are not to hard. Pay attention in class and do all the homework, plus his random quizes and you'll get an easy B or higher in his class. Mr. D Rocks!!!!

Okay yes, he does talk like Mr. Mackey from South Park. But he got me from a bad math student in hs to one who grasps calculus due to his clear, methodical problem explanations and willingness to go back and re-do things as much as necessary. GO TO CLASS & DON'T LET YOUR PHONE RING. NEVER talk back to him or laugh at him. Otherwise good teacher!

Attendance for pop-quizzes is crucial, class gets easier as semester goes on, got an A!

This math class was definitely a stepping stone in any direction for higher math. Mr. D helped me to understand the basics and taught from many angles. You take LOTS of notes but they are very helpful for references. Always go to class, and remember that he loves the Phillies (that will often be an extra credit question on the exam) :D

D'Alesandro was good teacher and he explained things very well. His tests tended to be very easy, but the homework was hard and at times tedious.

Best math professor....ever. Crystal clear. Funny. Tests aren't too bad but the homework is hard and very time consuming. Loved his class.

Funniest professor I've ever had. He's a huge goofball, but the class is really easy. He DOES sound like Mr. Mackay, but again, this adds to how funny he is. He's really sarcastic, too. The class is really easy, however, and it's difficult not to get an "A". Go to class, though, as he has a TON of pop quizzes.

EXTREMELY abrasive at first. Over time, however, he proves himself. He is very clear and patient with people who genuinely want to learn. Strict about classroom behavior to ensure good study environment. Semi-engaging lectures. Daily quizzes for attendance. Homework using Course Compass. Not a class to blow off, but easy overall.

I think he's a funny guy, and he really knows his stuff. Shows the origins of everything used in class while making it entertaining along the way. Homework and quizzes are easy, tests aren't too bad. Helpful when you ask him questions after class. I would definitely recommend him!

Awesome teacher! He really knows his calculus and is an excellent lecturer. He is a little full of himself, but its actually really funny when he he makes stuck up comments. RECOMMENDED

If you show up, pay attention, and ask for help you should do well. However, I found D'Alesandro somewhat annoying. My classmates was generally passive, so this could be abnormal, but he was often degrading and simply obnoxious. Plus he often makes mistakes in his examples, which is frustrating when you are trying to learn the the concepts.

I took MAT210 online, and even though the course is difficult, taking it online was amazing. All homework, test & quizes are online and follow the book exactly. The only thing that you have to study for is the midterm and final, which isn't even that high of a percentage of your grade.

Fun professor. He expects his students to be well-versed in prerequisites and be a little hard on you if you're not. Funny guy, willing to help if you put forth the effort.

I hadn't taken math for a few years so I was scared for this class but it really wasn't that bad. Tests aren't terribly difficult. Homework can be time consuming but he drops a few of your lowest scores. Doesn't make you take the final if you have an A! He really knows his stuff and I would definitely recommend him for this class.

just focus on the review guide prior to the test. All the problems on the test are from it. Funny guy very fair. Test are hand graded.

He doesn't really care if you come to class or not, and I never opened the required text once, so just buy the mathlab key. Very straightforward and clear in presenting the material, but doesn't like questions or confusion at all. Exams were all show your work (NO multiple choice), but weren't anything tricky.

Loves the Philles, superheroes, and sarcasm. Effectively teachers basic Calculus functions and with lesson time. Loves it when students come in for office hours-he is patient and personable. Quizzes and MathLab are your friends they boost your grade :)

He speaks English, teaches the class well & answers questions. Quizzes instead of attendance (he drops your worst ones), and the final isn't cumulative(easiest math final I've ever taken). Definitely recommend him.

Would recommend him. He can teach and explain everything. It's just really boring (if you don't like math). He's not easy to talk to. Drops three quizes and three homework assignments. Says class is mandatory in the beginning but never takes row. Don't buy the text...everything is from class notes or online.

He knows his math and can be somewhat difficult to approach but once you do, he is extremely helpful especially during his office hours. He really does care about teaching in his own way. Don't purchase book. His exams are just like the study guide make sure you know how to do study guide problems.

Very competent in his field. Explains subject matter well and is willing to meet with you in his office hours to go over material further. DO NOT BUY THE TEXTBOOK.

Yes he is a quirky guy but it's entertaining. He is always late at least 5-10 min before class. He is extremely helpful during office hours though. He also presented the material in a clear straight forward way. He made calculus simple and not as scary as society makes it out to be. The textbook is not required so buy at least WeBAssign access.

Although prof D may be a little strange and go off on weird tangents he is overall a wonderful professor. His lectures are really easy to follow. All assignments are super easy and he usually goes over them in class. Tests an quizzes also super easy if you paid attention in class. Usually lets class out early.

It's amazing how you can learn math when a professor speaks english. He's very easy to follow and specific in his examples. He can be a huge jerk sometimes (most of the time) but it's actually pretty funny and keeps class interesting.

He did not have a textbook which was nice - just homework available online. Very clear and concise. Made it really easy to understand - if you make an effort to show up to class and do the homework he will help you and spend the time until you get it. If you don't pay attention in class or don't show up he'll call you out.

If you put forth the effort and go to tutoring and his office hours when needed the class shouldn't be that hard. Also, doing well on all assignments and quizzes really boost your grade. He is one of my favorite professors. But he doesn't like students questioning his answers, and always challenges students who ask questions..so be ready to answer

Mr. D knows what he is doing when it comes to math. He had the tendency to go off on student who were rude and tried to prove him wrong (don't even try to prove him wrong, he knows his stuff). If you struggle in the class go to his office hours he is extremely patient and genuinely wants you to pass, much different than how he is in class.

Great professor. Apparently the people on here with issue with his "attitude" are used to simple arithmetic. He's thorough, smart, and I genuinely enjoyed his class.

Textbook is not needed. His notes are helpful if you write everything he does. 100 attempts on each hw problem so there's no problem to get 100% on them. He does kinda come off intimidating, but he actually teaches really well. Had class on T & Th but scheduled tests on Fridays. Final was on a Saturday. Has several quizzes.

Prof. D was a great teacher. Took him for Trig and ended up loving him. He is really wierd and will go off on tangents about the Phillies, but you can really tell he has a passion for what he teaches. You are expected to take notes, show up to class, and not be on your cell phone, but that is understandable. Tests just like study guides.

Very smart guy that knows how to teach. Quizzes and tests are fair. Put very little effort in class even though I'm not that good at calculus.

Great sense of humor!! Unlike other math classes i have taken, he doesn't just show how to do the problems, he tells you why. as long as you do the HW you will be set.

He was an amazing professor who was very patient in explaining material. Make sure you understand his practice exams to do well on the tests. He teaches calculus in a clear and concise manner. I went to office hours and he would explain material and made sure students were prepared for the exams.

SERIOUSLY LOVE THIS GUY!! BEST MATH TEACHER I HAD AT ASU!!!! I went to almost all of his office hours and with his help I got a 100% on my final!!!! He is simply amazing and will help you as much as you need and reexplain as many times as you want! If you struggle with math go to his office and you will ROCK IT! Seriously TAKE THIS TEACHER!!!

The dude knows calculus, and expects you to as well. His quizzes were pretty easy and although he could be boastful and rude at times, he's actually pretty funny and is patient when it comes to explaining something you don't understand. Don't be late, he HATES that. The tests are challenging and short, you either know the answer or you don't

Great lecturer and really knows what he is talking about. He has office hours almost every day and although he can get a little condescending, he will re-explain any concept to you if you ask. I definitely recommend taking this class with him.

Extremely smart guy who really knows his stuff. Teaches very well. Study guides are similar to the test but the tests are a little harder so take good notes! Smart ass teacher who will call you out infront of class if youre being disrespectful. Cracks witty jokes every now and then. One of the better math teachers I've had in a while.

D'Alesandro is by far the best math teacher I've ever had. He makes understanding calculus so fun, exciting, and EASY (seriously). Class is MANDATORY if you want to succeed. He is funny and I like his corky things he says, but do NOT piss him off, come high to class, or show up late. I would take another class from him in a heartbeat.

Pretty good professor. Can be funny, if you understand his sense of humor. Though, sometimes after class I'm left wondering if the professor actually knew what he was talking about. I don't mean to say that he's bad, but sometimes while doing a problem on the board, sometimes he messes up on something somewhat simple. Overall, smart guy though.

Good Lecturer and is helpful during office hours. Gives review exams that are very helpful for exams. Remember to be on time to class and come prepared or you will probably get called on. His lectures will easily keep your attention.

D'Alesandro is the most straightforward math professor I have ever had. His tests look just like the quizzes, homework, and worksheets. He is very clear about expectations, and although he can be intimidating, he will help if you need it. He also makes the material easy to learn. I'd highly recommend him.

Like others have said, the guy is very straight forward with tests and assignments. He does have an ego however and tends to call people out and doesn't really care if he offends anyone. Material and quiz's are easy but tests can be tricky due to the way some problems are set up. HW is sort of relevant. You'll need to learn a lot outside of class.

Easiest A in my life. He is super clear and a really easy grader. Tests are straight out of worksheets and reviews. Lectures are super short, and you don't need to go unless you really want to. Questions can be asked online and answered within the hour. Definitely recommend.

Easy class if you show up, and even if you don't you can still do well if you learn from the book. Tells you pretty much EXACTLY what's gonna be on the quizzes the class before they happen. Has a couple different webpages, he posts useful content on them. I found his blunt sarcasm during class to be absolutely hilarious.

This class is the EASIEST A I have ever got. He is straight forward and teaches you only what you need to know for the exams. He does not include proving in his teaching which is a huge plus to taking him. I honestly urge you to take him instead of any other mat 242 professor!

This is an Easy A. As long as you do his homework sheets, and the exam review, expect to get a 100% in his class. His lectures are so straight forward and so is his class overall. 5 tests, each 20% of your grade. That is all he grades. The test are so easy, right out of the worksheets and review. Excellent professor, definitely recommend!

Great professor, not many homework

Great Professor. talks a little bit fast, but just show up and you should be fine. his quizzes, homeworks, and exams are so easy. Don't ever buy the textbook.

I found D'Alesandro's class to be fairly easy. You're just graded on four tests. I didn't go to lecture and just reviewed the problems on his worksheets and test review and passed the class. Know how to use the matrix functions on your calculator. He is fairly helpful, but fairly technical in his explanations. Just do the problems and you'll pass.

Hilarious

He isn't the nicest person, but he knows what he is doing. His class isn't that hard and he teaches you all the material. Also all of his tests are just like the practice tests with different numbers so definitely do those. Do your homework and the practice tests and you should be fine.

His Linear Algebra class is basically just a rundown on how to use matrices to solve for variables. He's really abrasive, but he does everything in class, but if you want you can use just the study aid he recommended and the handout and you will 100% definitely get a B or better so long as you do the work and show up for tests. WRITE THE EXAMPLES.
