[[ExactlyWhatItSaysOnTheTin A teacher...who is cool]]. They motivate their students to learn (possibly in fun ways that are actually fun), laugh at the SternTeacher and MisplacedKindergartenTeacher behind their backs, [[BadassTeacher protect]] their students from the SadistTeacher and oppose the EvilTeacher and DeanBitterman at every turn. Their consistently good results might protect them from being a FiredTeacher, but this isn't a given. A lot of these end up being TheMentor either way.

Often a {{Foil}} to the ApatheticTeacher.

Supertrope to: PsychologistTeacher and BadassTeacher

!!Examples:

[[foldercontrol]]

[[folder:Anime & Manga]]
* Shizuka [[CatGirl Nekonome]] in ''RosarioToVampire'' is one of the few teachers who happens to be generally nice to everyone, enthusiatic about her job and helping her students learn, and actively encourages her students to participate in extracurricular activities. She does have a nasty habit of scratching her students whenever they point out something about her cat nature, though... even if it is for her own genuine good and protection.
* This is the entire premise of ''GreatTeacherOnizuka''. Onizuka is so much of a supportive teacher to his student's own problems, that very shortly into the series, he already had his own female students throwing him their panties in appreciation. He's not even ''that'' kind of teacher either..... most of the time.
* Takamichi of ''MahouSenseiNegima'' is often viewed as this. Negi kind of counts.
* Monsieur Dufarge, Sara's French teacher in ''ShokojoSera'', is a good example, and ends up being a [[TheMentor father figure]] to her. Of course, this leads to [[FiredTeacher inevitable consequences]], given the [[TearJerker sort of series it is.]]
* ''FruitsBasket'' (manga only) has "Mayu-[[SenseiChan Chan-Sensei]]" as the girl students call her. At one point she pretends to get angry, then grins and tells them to refer to her as "[[ShoutOut Great Teacher Mayuko]]".
[[/folder]]

[[folder:Film]]
* Ms. Oishi, the beloved elementary school teacher in Japanese film ''[[Film/TwentyFourEyes Twenty-Four Eyes]]''. She teaches her kids fun songs, takes them on hikes, and more importantly, reads them subversive literature and questions Japanese militarism.
* Mr. Freddy Shoop in ''Summer School''. Maybe a little too cool at times, but enforced in that he's just the gym teacher who was forced to teach remedial English or lose his job.
* Jaime Escalante, from ''StandAndDeliver'', which is based on an awesome true story (see Real Life, below).
* Dewey Finn in ''Film/SchoolOfRock'' is a {{Reconstruction}}. He is not a trained teacher and is only posing as one to earn some quick money, and then only intends to use the children to make money from the Battle of the Bands. But he comes to care for the children and his influence really helps bring them together. He doesn't help their grades but he does help their creativity and self expression a lot.
* Jack Griffith (played by ThomasHadenChurch) in ''Film/EasyA'', at least through Olive's eyes. Starts one class with a rap song, although he immediately stops, claiming that doing that is disrespectful.
* Mary in ''Film/TheMuppets'', such that her students simultaneously admit they'll miss her during their two-week Spring Break.
* Brendan in ''{{Film/Warrior}}'' is shown to be very popular and effective with his students. Once they learn he is also a {{Badass}} MMA fighter, he proves even ''more'' popular.
* Mr. John Keating in ''Film/DeadPoetsSociety'' founds the society in question and encourages his students to follow their dreams. [[spoiler: And becomes the TheScapegoat when one of his pupils is DrivenToSuicide by his overbearing father, although [[BittersweetEnding the rest take his words to heart]].]]
* ''Film/AmericanHistoryX'': Venice Beach High's school principal Dr. Sweeney was apparently so cool as a literature teacher that Derek still respected him even after becoming a skinhead. He also gives personal attention to Danny in hopes of turning him away from racism.
[[/folder]]

[[folder:Literature]]
* ''Creator/GoreVidal's'' ''Literature/{{Creation}}'' shows us the philosophy and practice of UsefulNotes/{{Confucius}} who is so cool that even the cynical Gore Vidal is in awe of him.
* ''Literature/HarryPotter'':
** Professor Lupin in ''Literature/HarryPotterAndThePrisonerOfAzkaban'' (in his later appearances he was no longer a teacher) and [[spoiler: [[EvilTeacher impostor]]]] Moody in book 4. Hagrid also counted while he was care of magical creatures teacher (although his lessons got a bit dangerous) as well.
** In the film of ''[[Film/HarryPotter Harry Potter and the Order of the Phoenix]]'', when Harry himself becomes a teacher of sorts for Dumbledore's Army, DanielRadcliffe suggested that Harry dress somewhat like Lupin in those scenes because he was the teacher he liked best and most wanted to emulate. Awww. The other teachers have shades of this (Evil ones like [[TyrantTakesTheHelm Umbridge]] and The Carrows notwithstanding as well as the incredibly boring Binns), although they tend to fit better into other categories.
* Susan Sto Helit counts, by ''[[Discworld/ThiefOfTime Thief Of Time]]''. She takes her students on field trips to battlefields and other continents, and has bogeymen and Death himself come in to talk to them. Overlaps with BadassTeacher.
* Honoria Bulstrode, headmistress of Meadowbanks, from the Creator/AgathaChristie novel ''Cat Among the Pigeons''. She's not overly strict, but she seems to have an almost telepathic knowledge of everything that goes on at her school. Eileen Rich, the English teacher, also qualifies.
* Miss Bulstrode's friend Miss Emlyn from ''Halloween Party''. Miss Emlyn actually figures out who the killer is before Poirot does, though she doesn't have enough evidence to go to the police, and Poirot consults her on several details of his plan before executing it.
* In the 6th ''Literature/CiaphasCain'' book, Ciaphas seems to have become one of these (he admits to being more relaxed than the other teachers and seems more than willing to take his trainee commissars into the field to get some experience).
* Aristo in ''Literature/TheRomanMysteries'' in the tutor of the four main character. He doubles as a HotTeacher.
* Several mentors in ''Literature/WarriorCats'' are seen as cool by their apprentices. Bluestar in particular was thought of as awesome by her student [[TheHero Firestar]].
[[/folder]]

[[folder:Live-Action TV]]
* ''TheBradyBunch'': How Peter tries to play up dull, old science teacher Mr. Price in "The Power of the Press." It doesn't work.
* On ''SaturdayNightLive'', Seth Meyers played the titular ''Cool Teacher''. On this occasion, however, he gets pushed aside by an even cooler teacher with a beanie hat, no tie, and hair like Garth from Wayne's World. Eventually, he was revealed to be a crotchety, bitter fellow teacher in a wig who was attempting to subvert Cool Teacher.
* In ''Series/BoyMeetsWorld'':
** There was a cool teacher named Mr. Turner, and a "square" one, Mr. Feeny, who actually turns out to be something of a cool teacher and mentor to the students himself.
** In one episode Eric takes over teaching a citizenship class for immigrants and turns out to be a rather cool (and incredibly gifted) teacher himself.
** In ''Boy Meets World'' there was an episode when they were in college where they had a "cool" young professor, played by Fred Savage (Ben's [[RealLifeRelative real-life older brother]]). This episode kind of questions the trope because the professor doesn't respect boundaries--he tries to sleep with Topanga.
* In ''Series/MySoCalledLife'', a challenging but inspirational teacher has a brief stay at the school and seems to be the only teacher to care that Jordan can't read. Ultimately he's forced out when some skeletons in his personal life come to light, leaving his former students confused.
* ''Series/{{Glee}}'':
** Mr. Schuester is definitely this. Bonus points for being one of the main characters in the show.
** Emma Pillsbury also has shades of this, however she's just the [[PsychologistTeacher guidance counselor]] and is a tiny bit to occupied with [[SuperOCD her own problems]].
** Substitute teacher Hollie Holliday turned out to be a very cool teacher and was considered even cooler than Mr Shuester. However, she took it too far and let Mercedes sabotage Sue's car and was then unable to deal with the consequences.
* Dr. Thomas "Tommy" Oliver in Series/PowerRangersDinoThunder. Careers prior to teaching include superhero (more consecutive years doing so than anyone else on the planet), professional race-car driver, and mad scientist (he helped to create ''robot dinosaurs''). Won several martial arts competitions back when he was in school. Fit all of his college education, racecar driving, and mad science career into seven years. [[ArsonMurderAndJaywalking Has finally cut his hair into a cool hairstyle]].
* Mrs. Quick from ''Series/SabrinaTheTeenageWitch''. She's frequently there to put a stop to Mr. Kraft's SadistTeacher policies while also providing plenty of quirkiness herself.
* Mr. Futtstein from ''Series/ClarissaExplainsItAll''. Clarissa quotes him often, and everything she says about him makes him sound like the coolest teacher ever. Who else would give an assignment to watch TV for 24 hours straight to figure out how to improve it?
* Rod Belding from ''{{Saved by the Bell}}''. Later subverted when it turns out how much of a flake Rod is, willing to ditch his students on a field trip to have a date with a stewardess. Mr Belding tried to be the cool teacher, but was generally the ReasonableAuthorityFigure. It was only when a third party entered the scene that Belding would team up with his students and let his CoolTeacher flag fly.
* A repeated sketch in ArmstrongAndMiller (the {{Channel 4}} version) spoofed this. The skits starred a really CoolTeacher who would use his unorthodox teaching method and passion to teach life lessons and make sure his students get the most out of their education... until the bell would ring, at which point he would become the ultimate ApatheticTeacher, immediately pulling out a newspaper, sitting down and telling his students to "fuck off", in the process completely abandoning or even directly ''contradicting'' whatever message he'd been trying to teach mere seconds ago.
* Syrio Forel of ''Series/GameOfThrones'', Arya's "dancing master", who instructs her in both Braavosi swordfighting and [[LargeHam advanced scenery-chewing]].
* Dr. Dupree in ''TheFamousJettJackson'' has elements of this. He seems to be your typical English teacher, but he does, on occasion, do something fun. In one episode, Jett screws up royally with his family, at school (by reading Poe's ''Raven'' to a rap beat, causing Dupree to shut him down and claim he's disrespecting the author), and friends. He then appears to end up in a GroundhogDayLoop. On his third iteration, he manages to get everything right. Then it turns out to have been AllJustADream, except the first iteration, naturally. Except that things actually get better. His friend is no longer pissed at him, realizing he was right. His great-grandmother and his father admit they overreacted. At school, Dr. Dupree also admits that Jett's "performance" wasn't as bad as he initially thought. In his mind, Jett tried to mix Poe's poetry with the "urban poetry of rap", which was very popular with the students.
* Inverted with the Mr. Goodman character of ''SoRandom''. His attempts at being cool usually result in bodily harm, and his students awkwardly asking for him to teach them normally.
* ''Series/PersonOfInterest:'' Finch, posing as a substitute math teacher, explaining the number pi to a room full of bored high school students:
--> ... Which means that contained within this string of decimals is every single other number. Your birth date, combination to your locker, your Social Security number. It's all in there somewhere. and if you convert these decimals into letters, you would have every word that ever existed in every possible combination. The first syllable you spoke as a baby, the name of your latest crush. Your entire life story from beginning to end. Everything we ever say or do... all of the world's infinite possibilities rest within this one simple circle. Now, what you do with that information... what it's good for... well, that would be up to you.
* ''Series/TheVampireDiaries'': Alaric Saltzman. He's young, intelligent, good looking and he's a badass vampire hunter aside from being the school's history teacher.
* Bernard hedges in the British TV series "Please Sir," who begins as a butt monkey but later achieves this status through his genuine dedication and fairness.
* ''Series/DoctorWho'':
** Ian Chesterton is a science teacher who is also a big fan of pop music, surprising Susan by knowing fanboy details about the charts in the first episode and dancing to Music/TheBeatles in "The Chase" (and the Telos novella ''Time and Relative''). He's also young, friendly, handsome, an ActionHero companion and travels through time, though not beyond [[DeadpanSnarker teacher sarcasm]].
** Clara Oswald has become one in "Day of the Doctor". She teaches English, has a motorbike, is young and pretty and fashionable, and time travels.

[[folder:Video Games]]
* Jack, the former WoobieDestroyerOfWorlds, becomes this in ''VideoGame/MassEffect3'' if she survived the previous game, to students at Grissom Academy.
[[/folder]]

[[folder:Web Original]]
* In ''Literature/LovelaceOneTwo'', Mr. Stone -- Andi's mentor -- is highly supportive of his students and tries to do his best by them. In [[http://banter-latte.annotations.com/2013/06/26/story-day-lovelace-12-part-4/ Part 4]], Andi describes him as buying into "the [='=]''Film/DeadPoetsSociety''[='=] thing."
-->'''Mr. Stone:''' Are you kidding? No way. Creator/RobinWilliams was a ''terrible'' teacher in that movie. Seriously, aphorisms and pep talks donít teach [[Creator/WilliamBlake Blake]].

[[folder:Western Animation]]
* Parodied in ''WesternAnimation/SouthPark'' with Mr. Cartmanez.
* ''TheMagicSchoolBus'' has Ms. Frizzle. She has a pet chameleon, her school bus can go anywhere in time or space, and nothing ever fazes her.
* ''WesternAnimation/{{Recess}}'':
** One episode had a former student (and rival of SadistTeacher Ms. Finster) return to the school to work as a teacher. By the end of the episode he's reconciled his love of science with his aversion to being boring and became one of these.
** The mysterious Mr. E, a substitute teacher who wins over the entire class with the exception of TJ, who's appalled at how quickly they forgot about Ms. Grotke.
** Miss Grotke's a pretty cool teacher herself as well.
* ''WesternAnimation/AvatarTheLastAirbender'':
** Monk Gyatso teaches [[TheHero Aang]] to [[BlowYouAway airbend]] [[PieInTheFace pies at other, meditating monks]]. While the other senior monks at the Southern Air Temple take a more disciplinarian stance and want to accelerate Aang's training because of the war on the horizon, Gyatso insists that he have a happy childhood.
** [[CoolOldGuy Uncle]] [[RetiredBadass Iroh]] also counts. Just watch any scene where he's teaching Zuko a lesson in fire-bending or general life lessons. [[ParentalSubstitute He's more of a father to Zuko than his actual father.]]
* Miss Finch on ''{{Birdz}}'' is generally supportive of Eddie. In one episode, she allows him to shoot a video essay instead of writing one, to support his love of filmmaking.
* The science teacher in Frankenweenie sort of counts, though it can be a little unclear due to the gloomy tone of the film. But he is clearly very excited about his subject, illustrates his points with theatrical story telling, gestures and chalk drawings and chides the adults of the town for being small-minded and preventing him from expanding their children's minds, even if he has an (on the surface) fairly threatening way of saying it. He also listens and gives advice to Victor when he asks him a question outside of the classroom and tells him its important to love his project. Note that most of the class is very excited about the Science Fair, and that the children don't seem very happy with their substitute when he is fired.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', Twilight Sparkle becomes for the CMC, a special tutor who takes special time to help our favorite fillies find their true potential.
** And [[BigGood Princess Celestia]] is one for Twilight in turn.

[[folder:Real Life]]
* Many people will have "that one teacher" who is just plain awesome and does things his/her own way.
* Purportedly, SomethingAwful Goon/high school science/forensics teacher Gene Splicer is this: "Who was the one who brought the maggots so the students could mess around with them? Me!" The other known teacher-goonette, English professor(?) Jidohabankai (this is almost certainly wrong) is more of a SadistTeacher [[JerkWithAHeartOfGold With A Heart Of Gold]] (she does terrible things to cell phones that dare to ring during classtime).
* Jaime Escalante, made famous by Edward James Olmos' portrayal in ''Stand and Deliver'', was a Bolivian immigrant who came to Los Angeles to teach computer literacy at an inner city school. Only, when he arrived, there were no computers, so instead he started teaching math, including starting an AP Calculus class. Despite numerous naysayers, his AP class consistently had the highest test passage rate in the country (so high that at one point they were investigated for cheating, but were exonerated). He was so beloved by his students that they stole his car in order to fix it up for him (many of his successful students were former delinquents). On the side, he taught remedial math and an English class for immigrants at night.
* CarlSagan. Many of his own students are now big-time celebrity scientists in their own right. NeilDeGrasseTyson might be the most famous example. [[BillNyeTheScienceGuy Bill Nye]] is another.
* Salman Khan, founder of [[http://www.khanacademy.org/ Khan Academy]], is the Internet's official CoolTeacher.
