- "Why are exams so hard? Why do teachers write such hard exams?" One teacher's perspective.
I'm Mr. Woo and my channel is all about learning - I love doing it, and I love helping others to do it too. I guess that's why I became a teacher! I hope you get something out of these videos - I upload almost every weekday, so subscribe to find out when there's something new!

I don’t mind when exams are difficult... I just despise when there are questions on the exam that we didn’t even learn.
Tariq Sarhan Which is why you study. You’re not supposed to be taught everything in school. Governments want people to Study themselves without full help from others.
Yeah Yeah out of program!
Then you miss the point. The point of school, particularly mathematics, is to train you to think for yourself. Even if you weren't taught about a certain question directly, you can attempt to combine the theory you did learn about and see where that gets you. Usually, the last question on a math exam is like that. Everyone can copy what they were told in class, but when you really understand the essence of the theory, you can extrapolate its applicability into related domains.
@@ahdkfknsbcienfnsk It's expected that you will be taught the things that allow you to answer the questions up to a point. That's why there aren't biology questions on math exams. Some instructors give questions that are a good extension of what was taught, but others give out questions that are not.
Teaching is failing us to understand concepts, understanding concepts allows you to apply those concepts to any situation and so whilst you may not have directly learnt how to answer something, you would have been taught a concept that relates to it . Teachers however teach in a very systematic way teaching you how how to do something rather than understanding how to apply concepts to difficult situations
Finlands education system shows to me that there is probably something fundamentally wrong with preparing for a test instead of learning. Like for maths, you'd rather learn how to answer exam questions properly instead of gaining a true and intuitive understanding
@@bilaltariq7819 College and university is basically the same thing XD
I don't want to get grades that are ranked to other people. I want my grades to be ranked to how good I understand the subject and how good I work on the tasks.
I didn't get that; here exams are graded on their own, no one compares them to the other people who took it. Where is this where the marks are meaningful just on a scale of all results?
I agree that using exams as a means to compare students is flawed. To me, the emphasis is understanding of the material to a high level.
If you have 120 students and need to split them into 4 classes of 30 students each, basically the only rational way to do that is to rank them. Like, it's not a choice that they're making, it's just what falls out of the problem at hand.
How r u going to be graded on how well u understand the subject if ur score is not compared to others? There has to be a standard of measure
@@usersdksdfg no offense but I’m mentally retarded so I rather not be compared to other normal beings
0:00 Why hard exams?
1:08 1. Marks/Grades/Rank
2:58 2. Easy exams don’t distinguish skill level
5:08 3. Difficult Exams help you learn
- Adding constraints allows one to grow stronger
9:06 4. Difficult is relative
1. It was a hard exam
2. You were not ready, let’s work on practice
11:49 5. Exams are not the most important thing in the world
There's a lot of base assumptions here that we can question.
Why is performance under pressure more demonstrative of a student's understanding than tasks without immediate time constraints?
Why should a student's access to more advanced courses be dictated by the performance of his peers?
Why is it more useful for letter grades to reflect competitive advantage?
For 1, I'm not sure how else we can systematically and objectively measure a student's ability. If you can give some suggestions, I would be happy to listen.
for 2, he directly addressed this. He talked about how a kid that doesn't belong will struggle. It's not like every year they say that class A will finish the course in 4 months, B in 6 months and C will be right before trials. They adapt to the group that they have. If all of the kids are of a high standard, than they will all go through the course in the pace that suits them because the teacher can sense the level of understanding within the room. They are being judged compared to their peers because first, they need to make sure that a class is at least homogenous in skill level before they can teach the most amount of kids at the correct pace for them.
For 3, I think i need some more clarification because I'm not sure what you are trying to say.
Some of my professors have expressed that exams under pressure do not fit all students as a means of testing their understanding. One professor (when he’s on tenior lol) will give students the option to present research to the class and explain their reasoning using the concepts. In that way they show their understanding by explaining it, use the concepts and apply them to a higher level to demonstrate mastery, and to explore actual real world applications of the Physics material that they might see in the real world. For some people exams are the best gauge of mastery, others it’s not. We should not demand that exams are a one size fits all for all students, in my opinion. There are even more options than above available
For 1 well education is educating for life right so performance under pressure helps you to become adaptable and quick in thinking creative stuff and time is something which all of us have in limited manner so it's pretty helpful and time constraints also test the understanding more have you ever noticed well prepared students finish thier papers first mostly and medium and not so prepared students mostly submit st the brink of time...
@@ybvb ya man I completely agree but there's thing which I came to know recently that actually some people actually prefer normal life than some billionaire thing.Not to mention they get satisfaction out of the subject itself which is pretty awarding ,ya then again you are right here that gives School no right to "train" em all the same but what I think is whether you want to be rich or not a subject,has its own beauty some like it some don't but some are taught in the wrong way which takes away interest from students that's my only concern. School at times take curiosity out and as you said even thinking outside box Which actually is fun.School takes away "fun" and asks students to study all the time.
Why would I do something which ain't fun?
👏🏻👏🏻👏🏻
Mr. Woo is a master at explaining complex things. I thought he was a master of math. This video shows that he is precise and articulate in whatever he explains.
I came first in a 3U exam and the top mark was 64%.
Ooooooooh!
3U?

The difficulty might also just be a psychological effect. I mean, last math test I had was the easiest in the whole year. Really, the hardest geometry question just required you to apply a formula the teacher taught us less than a week before, and more than half the class failed it. Even the teacher himself said the test was really easy and that he wasn't really sure he should put that question in there, because he felt like he was just giving marks away. And when he solved it on the board in less than a minute the day after, all I saw was people with really sad faces in the class, who told me later they felt really stupid. I guess it's like a little chain reaction: you find it hard, get distracted by yourself and regret it later. Great video, it's also nice hear the teacher's point of view.
It was just like the SA-1 math test last year
A Ukrainian woman told me once the motto of the Ukrainian army:
“Tough in training, easy on the battlefield.”
Perfectly said.

Hi Eddie - thank you for all your good work. I am a computer science tutor at an Australian university, and have often wondered: Why should school students be ranked? At the end of a semester, if a student demonstrates the objectives (e.g. 'competent with linear systems', 'competent with complex numbers', etc.) - why does it matter how they compare to other students? At the end of the day, a professional either *is* competent, or *is not* competent. This is how students are treated at University as well - they are not ranked, they merely receive a mark of competence. When I was in high school, I was very frustrated by how teachers never presented 'A level questions' - meaning, there were no questions available that I could practice or study to adequately prepare myself for the exam. I found this to be unfair, and it does not represent how learning is done at a tertiary level. The exam questions were intentionally more difficult than anything I had seen previously, so that the select few students who could decode them could help to form a bell-curve.
These are basically my same reasons why I create more challenging exams and curve them, rather than just putting problems they've seen and have memorized the "how to" for solving those specific problems (with numbers switched around). Thank you for this perspective!
It's kinda hard not to put emphasis on them if they are external exams that you get a qualification for.
I am of the opinion that everyone should know the subject well-enough to get an A. No need for a skill-separating test. Just test for what has been taught. The onus should also be on the teacher's ability to impart the concepts as well. The point here seems on sorting rather than teaching. Maybe that is not possible in a public school setting. Iron out the areas of weakness before the exam. Focus on mastery of the subject rather than the grade or the exams.
That already exists, it's called a certificate. You are technically only required to pass and if passing is all you care about, you don't need to heed grades at all.
If the exam is easy, then what's the point in doing it in the first place. I find no satisfaction in passing an easy exam!
It's not like an exam either has to be easy or it has to be really hard. The point of an exam is to give the student a chance to demonstrate to the teacher what they know and how well they can apply what they know. That should be it. It shouldn't be a "math olympics" type of competition among students where your grade is based off on how well you can do several really difficult thought and time consuming problems under high stress and a time limit. It stresses you out and limits your ability to think clearly and perform the way you'd usually do. The most unnecessarily frustrating thing that can happen in a math exam is when you do something wrong that otherwise wouldn't be a problem, because you're not thinking straight and used up a lot of energy to do several other difficult problems for 4-5 hours already. A math exam where how well you can handle stress can be a deciding factor on whether you get an A or a B is in my opinion a bad exam.
During our third year University (Engineering) exam on a certain subject, the exam questions were so hard that 90% of the students failed. What happened was that all the papers were "re-marked" with square-root times 10. For example, if you scored 25, square-root it to get 5 and times 10, you'd get the passing mark of 50.
This goes to the fundae of human beings or living beings....
We all want to survive at any cost....
Idea of examination is to check/ quantify peoples according to their skills and intelligence..
which is one factor for replacing wars with pens, we shifted from physical survival to mental survival. (understand it i couldn't put it better)
well said!
That is very true ;)
Thank you Mr. Woo! I'm having a ahhhhhaaaa moment....I just finished college. My MOST difficult class was Algebra. But my FAVORITE CLASS. Probably because I learned that's where I am weakest----I felt like "wooptedoo that I got A's in all my other classes"---I didn't celebrate those sometimes "easy A's" like I did the C+ I got in College Algebra--- Especially since so many had to take the class more than once. I think humans LIKE challenges. Math is a challenge. Hard tests are a challenge, like he said, and personally instruct the mind on where we need to IMPROVE and become STRONGER. Good discussion.
When I was in graduate school you took quizzes every week to test knowledge of physics and use of mathematical tools. It trained you to know what expect from homework and what instructors thought was important for exams. It trained you to take the test, get over that hysterical reaction to exams.
Excellent commentary - "don't just question the exam, question yourself as well", "marks are relative". Thank you!
If exams tell you where your weakness lay, then do it in the mid term, a few, to id the issues and aid in the finals.
Why is time pressure a proxy for understanding? Some people take longer than others to work through a problem.
And then depending on the severity of the person's problems, can be distributed extra time if the person is diagnozed to need extra time. Unfortunate but in fact the reality.
difficulty of an exam and level of competence are both concepts that are mutual, that is that they go hand in hand, and are not distinct
which is partly why exams are bad at gauging level of competence over a whole field. you're gauging the level of competence over ... the exam itself
they can estimate but they fail alot of the time at doing so
Exams cause me stress so it could probably make it even hard for me to remember everything I've learnt
You are so patient!
Thanks for explanation. Education is one thing, competition is another. I don’t agree to mix them together. My understanding is that education is to enlighten kids, not making competition among kids.
It's not really a competition. It's to separate "better" students from "worse".
Why do you want to separate them then?
@@jackzhu5094 Huh? I'm not saying they should be split into 2 classes 1 bad class and 1 good class. Better students deserves higher grades and worse students deserves worse grades... if the exam is the easiest of the easiest then better students gets the same grade as someone worse if everyone can score max points... Let me ask, how old are you or, is your logical thinking disrupted or damaged in some way? A better student deserves higher grading.
You are hopeless.
@@jackzhu5094 How am I hopeless? You are not bringing anything of value to this discussion by defending your standpoint. I don't agree with your viewpoint since it's a tilted way of looking at it. The teacher in this video brought up some good points why an exam should be harder. And one of them is that better students shouldn't get the same grade as the students considered as "bad". Hate to use the word bad but read between the lines. If you don't bring anything of value from now on I'm going to ignore you because then you are simply just ignorant and simple minded.
Your work is amazing sir! So proud of you and where you've come. Your work ethic & passion is everything. Makes me so proud to go to CTHS, knowing that you've made such an impact within the school itself and now the globe!
I don't mind difficulty. I do hate when teachers got preferences. I was told once in an economy test "the writing part was perfect, in the oral presentation you hasitated in the last question, so I think it is better if you try again next time". Wtf. Then I learnt those teachers always turned down the studients the first time they presented to that exam. No matter what.
The only problem I have with exams isn‘t how hard it is but rather will the knowledges required for the test even be used once for the rest of my life or just a waste of time. Middle and high school exams are like torture to me because I have to learn tons of things for a test and after that trash can is ready.
Hi Eddie, I'm wondering how you explain what "negative gearing" is to a teenager?
A corollary to #3.Scoring very high on several hard exams in an area that can tell you, and others that you might be able to make good living doing what was tested. This happened for me and I had a productive career in molecular biology. Easy exams way not have lead me down this path or at least may not have given me the confidence that I could succeed.
Dear Eddie,
I am sorry, but I do not agree with what you say. You give it for granted a “hard” exam is a “fair” exam, but what students (serious one) are very disappointed about are exams that are unfair, and because of that, difficult.
I define unfair an exam that is clearly covering topics out of syllabus, or, covered minimally in the classroom. Sometimes teachers put a video online after the last lecture with additional topics to learn, giving students an unfair additional burden to handle. I remind you that students are not only occupied with one exam, often they are workers having an hard time to schedule and handle their time efficiently.
You teachers have not an obligation to make easy exams, but you need to do so fairly. Fairly means with clear rules stated in advance. Fairly means giving the time available to your students a due consideration. Fairly means to accepts critics (were constructive) and try to improve. Fair means, easier questions first and difficult questions after (you don’t want a student to waste time or get panicked reading the first question).
You teachers are not doing that. And the truth is that, if you are not doing that, is because your are give ample and almost unlimited authority over exam structure and content. The study that exams questions are reviewed by a committee is just indicating that the exam would be accepted as valid by a professional body, and must not be taken as an indication of its fairness.
As regards your point on performance vis a vis other students. Sometimes you have part time students taking exams with full time students. You have students who learned additional topics in a subject that, accordingly to the program, you are supposed to take in future. You will never have a fair assessment in this way.
Therefore, for the reasons expounded, I believe your points are weak and that is just giving a invalid excuse (not justification as no greater good is achieved) for your way of making exams.
1. "Raw marks are meaningless". They are used to distinguish between people as you said later so yes they must have meaning. If marks were meaningless then why would you bother with them at all?
2. Distinguishability. Great. Make tests difficult but don't make it artificially difficult by enforcing time pressures.
3. Learning. "It's the same in all areas of life" - Disagree. Many professors say the cliche "just wait for the real world" but actually the real world isn't filling in a piece of paper in 3 hours.
4. "Difficulty is relative". This is a nothing point. Everything is relative.
5. You have conflated the issue here. The importance of an exam is not placed by the individual but by the corrupt North American education system that values people based on flawed measurements. University's primary purposes are no longer educating society but milking society. They are a business who treat students as a means to a bottom line.
I like your videos but you need to come back to reality in this one.
Edit: Point 5 only applies to North America. If you are talking about a different country then maybe they actually have respect for learning there.
hes talking about Australia
an Exam shall be fair. Not easy and Not hard. extreems are bad either ways ...if its hard, it can demotivate students ... it plays on selfesteem and breaks down those who try hard... easy is not better its such a lie ... a fair exam is what its all about.
What many people fail to realize is that the 100% mark on that exam is reserved to a really small amount of students that are able to achieve that. Even if there was only 1 single person that was able to achieve that 100% mark, the exam was fair, as it tested everyone to their extent. And I'm pretty sure that there will *always* be that guy that was able to achieve a full 100% mark on that really hard exam that the majority of the students had such a hard time passing. If there was actually no one who could achieve that, then you could say that the exam was perhaps harder than it should've been.
@Zhanmin Wang 1 year after posting that comment I've come to realize the education system is just a means of pushing out robots to the world that are just used to memorizing information and have no creativity at all. 1 year later I've also come to realize what I wrote on that comment is as arrogant as can be 😂. So in conclusion, the OP is right, exams should be fair, and in a case like yours it would be a pity if no one tried to make a difference as it is clear that everyone in that school is having a hard time.
I don't mind the continual assessment of Elevate. I am also trying out Khan Academy at the moment to improve my maths. As far as exams go, I don't like questions that completely confuse me. I prefer the idea of continual improvement by regular assessment at your own speed.
You have aggrandize my desire for more involved experiences! Now onto diligence and perseverance... Thanks for the advices!
I thought you are talking about joint entrance exam (JEE)...
I thought u were talking about joint electricity exam
The exam is to examine to things:
1-your attained knowledge.
2-how to employ it in other issues.
if the two requirements aren’t met then its a fail from the teacher to evaluate the level of their students understanding .
Its not about the level of the exam its about what is the hidden goal behind it.
An easy conceptual short exam makes better feedback compared to a 10000 exam with no goal just to make the students suffer for the rest of their life.
YET, please teachers take the exam writing like a painting you wont to make every one smile when they see it and a beautiful memory at the end of the coarse.
2:20 NO it doesnt, how the hell Am I suppoused to get scholarship, which needs minimum 4.75 if I will get 4.0 from your test, and I was the best in the whole class?
Ok, I am editing my comment. You are talking about your country education system. Its totally different in other countries.

Why are exams so hard?
Because they always asked things that I don't know and not on things I know.

You are making no sense. The teachers are the ones, who make the exams.

Since you seem to be unable to parse it yourself, here's some help. He said there is nothing wrong with the exam, but also that the teacher might be incompetent. Do you notice something? If not, read my comment above.

i wish eddie, i wish..
megatrook it's funny because teachers mark up the value of any exam ever undertaken, but I look back on every exam I ever took (I have took A LOT) and none of them matter
I aced exams at school and then university for more than a decade. My pay packet is average for my age.
I followed him and enjoyed most of your teaching videos. You're a very good teacher. But your explanation for why exams should be hard doesn't make good sense. You make it a competitive paper chase rather than a confidence-building learning experience. Building a student's confidence so they'll have the skill to take on difficult math challenges should be the focus of your effort as a teacher. Just my opinion
i completely agree. that's the exam and grades system for you :X
He is not the one who created this system. He is telling us how we should deal with the current system.
@@derjemand1021
I never said he created this system. I'm talking about how to respond to it. Building a student's confidence with many small accomplishments is the very best way to do it. Hustling through something with rote memorization is the worst
vf84tcat1 I understand your point and I agree. I really like that guy too. But my point is that if he wanted to make a video about the things that lack in our system these points you made would be for that video. This video is more of a how to deal with the current system.
Here they gave us the practice test from the week before, just because everyone kept failing the other tests... They're trying to force our grades up because our school has some of the worst graduation rates in my country 💀💀
Only difficult when your not prepared
.... but my school doesn't put you in different classes based on how you performed on tests... this must be an Australian thing (I'm Norwegian).
What if your the only one that finds the test hard?
Easy exams also make easy graduates which leads to people being less prepared for the real world where they don't make things easy just because you're having a hard time on them. Imagine your doctor passing his study with a 60% marks on easy exams, I wouldn't want to be treated by that doctor.
thx for that video
Thank you so much! Actually pretty life changing advice.
Love your videos :)
I agree with what you said.
But as a past year HSC student. I never blame exams. Note my English and chemistry teacher literally did not teach us anything, we learned everything ourselves from textbooks, but I don't even blame teachers.
I blame the system is inadequate, a competent system should scrutinise for incompetent teachers and increase frequency for examinations. People get nervous for trial and yearly is simply because they haven't got enough simulations. When you get to uni you'll know current high school content is child's play.
Also, the reason I did not get into 3unit math and subsequently 4 unit math is simply because I did not understand English and terms like hypotenuse when I first got here.then we got put into teachers with their name on the staff board but no skills. I don't see myself as a genius but I'm pretty sure I could've done way better, so could my other classmates.
The system is rusty that's all.
.....Advices is incorrect because it's a non-count noun. Thanks for your advice!
everyone in the comment section defending professors has never had a hard exam. Yeah yeah, ever done all the homework and then in exam period they give you 3 days each for an exam to study maximum? You couldnt do revision earlier because there s too much homework and then they make the exams so difficult 80% fails. now who passes the exams? You think geniuses pass? Let me tell you it s 90% people who do it for the second time or who have half as many classes as recommended, making bachelor unnecessarily long for everyone
u either die a hero, or long live to see urself become the villain.
Dear Mr Woo. Why not have a scale? Easy, middle, hard, nearly impossible , easy, middle , hard. Two of the things i hated about math in particular was that every test was nearly impossible not only because i am a bit learning disabled but also because i was miss taught in the first place. also the dreaded show your work sentence just plain depressed me. I worked hard, i got the right answer and now the teacher comes up and says i want you to show your work.like i would be able to remember all the steps i went through to get the right answer but also i would be singled out socially which is irritating at the best of times. Now i have'nt been in school in many years.(I will be 53 my next birthday) but being something of a mad scientist i still dabble in creation and i find thing hard to do when you cant get beyond basic math. A scale will give some students some breathing room and allow you to pick out problem areas in some students and if there are none then great. You can pound them into the dirt with the nearly impossible test later and that too will show you who has a better grasp of the material. By the way do you know what a number wheel is? its a bit of math history i came across here in the United States.
Thank you for the advises.
Exam is easy. Copying is hard.
I really don't like when there are so many questions on exams
Because it takes so much time and tires you out
aw boo hoo
This was great, needed to hear it. Thank you
Sir it's serious please help
Exams are hard?
Is that why AP1 3 U was impossible
Why do we have exams? Since leaving education for more than 25 years I have not sat an exam or required any information I used in an exam. If I did not know something I would simply go and look it up and up and use the information I found.
I have now return to education after a 25 years hiatus, and still they use exams as a means of gauging's someone ability. An exam is not a means of gauges someone ability, it is simply there to test the memory of the person taking the test/exam. It proves nothing. It is simply there to make the work of the examiner easier, as they don't have to sit there and read lots of work, mark it and leave feedback of how to improve next time. They simply have a marking scheme and say yes its right or wrong. There are far better ways to test the abilities of people than tests/exams.
mee too when I am a student

good advices and im the kid at cheso who was at the compass excursion.
Hold up... the derivative of lg(cos(x)) isnt tanx... its -(1/ln10)tanx....
I think he said ln (cos x)
its not about easy or hard its about mid type is the most appropiate. i dont agree with hard nor easy ones.
Yeah yeah yeah, study 300 terrible slides for 3 questions exam and tell me about how hard exams help me
I feel your pain more than anyone. 300 slides at 1 am that you didn't have time to study cuz you are studying for midterm exams and they give you no time between each exam so you can fail and pay for classes in summer, Its just business at this point. if 8 subject didn't slip under the pressure and no time, the 9th subject will.
If the first question is too difficult that I can't answer it, I immediately quit the whole exam. I know I won't be able to do the whole exam, so why bother?
As far as I have experienced and understand, examination results do not provide information on why a student fail at some questions but succeed at others. Though there are many factors that could possibly affect a student's performance during an exam, it is very likely that none of that would be taken into consideration when grading his papers. Therefore, exams are the least effective way to either judge a student's ability or capacity or knowledge or level of learning. When exams do not motivate students, it discourages and belittle them. But of course, many people are gonna disagree with this, just as employers only look at paper qualifications and not actual acquired skills. It is the lazy way to analyze one's abilities.
Thank u sir for your tips.
Exams aren't generally hard. I've had much more easy exams than hard ones - even the ones on hard topics were generally much easier than the exercises.
Missed opportunity on point 2:
If exams weren't hard (so then weak and strong students both do well), a strong student thinks he's only as good as a weak student. And that's not a good thing!
4:35 this was me in my mixed 2u/3u class
Exams are not hard it's just that the teachers gave the exam based on another topic while the students study something else, which is a bit foolish!
I think this is true for memorization exams(example: Biology). But as for exams such as math where the way of answering it can be played around it cannot be said the same unless that there is a chapter of materials that have not been taught before put onto the exam (example: You are learning Plus Minus but the exam suddenly have Multiplication)
Hi Mr Woo
I don't have a twitter or a facebook account so I thought I would ask my question here. When you were doing your HSC, how did you organise yourself and your time? I've recently started HSC and if you could give any advice and information it would be great. Thank you.

How hard are your exams?? Maybe it's just my experience, or maybe a difference in our curriculum, but our exams are not any more difficult then tests. If anything they a small amount easier then the tests. Granted, I do put a lot of studying and care into my work, so that itself will help me with exams and I might perceive them to be easy.
Let’s agree to disagree
then i challenge you to a duel
How is the derivative of logcos(x) = -tan(x)? I think you meant to say the natural log of cos(x) is -tan(x).
Derivative of log cos x is 1/cosx into -sinx. I think you should be able to do it now.
Thanks.

Do they have a UMS in Australia (if so)???

And found that others found it hard. You clarified things do much. Hope I get a good grade.
Thanks
Mr Woo, in India the board examinations are diluted. In other words, they are super simple and very lengthy and it is these exams that force students to take that last step. Please, as a teacher help me with my IIT entrance test preparation.
Yours sincerely, Aditya Nagesh
I feel bad for people who have strict parents expecting them to get an A? I don’t understand what’s wrong B?
Plan B is never as good as Plan A
Exams are a form of discrimination of intelligence.
Yep pretty much
Gotta appreciate hard exams hahaha that's funny but true
Hard exams as you say are learning experience. But unless you are going to be math teacher you will not be given another chance to use what you have learn. College student talking.

I don't see the point in sets. Surely every student can learn in a mixed group
My country (Albania) doesn't have sets, and I must say that it's not really what you think. Every class is composed by some students who spend the day in the same place and teachers come and go in and out of the class. In *every* class you have that one or more guys that whatever they do they don't seem to be able to grasp the subject, and also that other student that is extremely bored by the slow pace that the teacher is maintaining. I actually find sets a really interesting approach to making life easier and education more efficient for everyone.
"raw marks are meaningless" already instantly proves why exams are useless
Then you didn't hear the explanation...
The marks are used to compare the students. It's not 'get a certain raw mark to get a certain grade', it's 'get a certain raw mark to get a certain grade, relative to the other students'.
School is cut throat business. It’s a bunch of arrogant people who think their the ish. People that do want to genuinely learn become discouraged of the lack of support from these institutions.
WHY ARE EXAMS SO HARD? There's no such a hard things.
Okay, I'm a lecturer. When I was a student I asked the same thing to myself.
1. For students: WHEN YOU FACE REALITY, YOU'LL FACE THE IMPOSSIBLE. Believe me, you wouldn't imagine this time.
2. For teachers: The way you teach, don't tell students to memorize constants, formulas, etc. DO IT TOGETHER, SOLVE THE IMPOSSIBLE TOGETHER WITH STUDENTS. So they will analyze instead of memorizing those things.
Eddie woo how are you .....
Got this question from Expert Systems quiz
topic : LISP
Please use X as the variable ----------------- ------------------- --------------------- X ----------- -------------- ------------------- ---------------- -------------- ----------------- ----------------------
So confused can you Assist
OK buddie thanks.
I am in South Africa, thanks for the time you gave me. I just started my Btech in IT, I got that question in an Introductory module to Expert systems
well i still hated all of my old exams. i think an exam shouldn´t be all difficult. it is frustrating. i sat in my maths exam like "fuck it. that´s a five anyway" (second to worst mark. spans from 25%- around 45%). just at least some fair questions that you can solve if you know the basic stuff you learned in class and you´re good. at least have god knows 20% of that. an exam that is 100% transfer is just hard and is at least for weaker students like i was nothing but hell. like i knew the week before maths exam my mood was down. and i knew the day of the exam, when i maybe would have needed the sugar/carbs i´d throw up my breakfast. i took dextrose against the headaches and ate the first time the day at lunch. i really hated maths exams. and they and the importance marks had at least here in germany really ruined maths for me. like they cemented i´m too stupid for maths. really that´s all what the exams told me. sure i could have prepared even more and maybe stopping preparing for them was the wrong call. but i really planned like this "i have one bad mark per semester and i can still take my finals. that mark is gonna be maths. so let´s push music out of the danger zone, well maybe my sorts teacher should see my face again. and i can pull out the four in music with my 1 in religion or latin" (1 is the best mark, 6 the worst and an automatic failure of the year. a five can be balanced out with a two. but at least in my federal state you only could balance out 4 times) in the end because i really saw no way to beat a maths exam without cheating. and i think even with an exam being challenging it should never destroy the subject for somebody.
i mean i know for you it is important to keep your students interested in maths. and i just saw rthat too heavy exams can really kill the interest. i´m two years since my last maths exam (mathematics for chemists) and it pretty much was around the time of that exam that i started to develop an interest in differentiation. really just in that because i was decent in it. and i was like "okay i´m good at that. but why the heck does it work?" (truth be told i memorized half the integration table and 80% of the time i was like. why is that like that? why is d(lnx)/dx=1/x for example? why is d(sinx)/dx)cosx? why is the exponential function it´s own derivative? stuff like that. i was more intersted in these memoriessed formulae at firs.t i had them down safely so i could waste brainpower on curiosity)
Could use the analogy of Dragon Ball - Goku Training With Weights (th-cam.com/video/7YGCDBjn-M4/w-d-xo.html)
