Student Product Self-Evaluation Form: Fill & Download for Free

My interview was to be held in the KVPY building in IISc on January 27th.I reached the venue about an hour or so early and approached the lady at the reception to hand over all my documents. I’d checked and double-checked to see which documents I was required to bring from the website but it turned out that they needed a photocopy of my tenth grade report card in addition to the ones I brought. Fortunately, I had enough time to go and get a photocopy made nearby.I found a classmate of mine amidst a crowd of about 50 students and took the vacant seat to his side. My classmate, however seemed to have read through the entirety of our 11th grade science portions but all I knew was what we’d been taught until then. Moreover, I wasn’t particularly confident about Inorganic chemistry (to say the least). I was already nervous but seeing my apparent lack of preparedness, I was becoming very anxious.I was the second person to be called to ‘Committee II’. As it happened, the first one was my aforementioned friend. I asked him how it went as he emerged from the room. He gestured back saying that he screwed up. Boy, was I nervous! Waiting outside the closed room, I could hear someone inside announcing me as the next candidate and proceeding to read out my self-evaluation form (submitted to the reception lady earlier). A couple of minutes later, I was called inside.If I remember correctly, there were 7 professors inside. Lets call them P1, P2, P3, M, C1, C2 and B. They asked me to take a seat and asked if I was from the same school as the last candidate. I replied in the affirmative. This is the conversation which followed:-P1: Which subjects do you like?Me: I like Physics and Math.(C1, C2 and B look a little disappointed, lol)P1: Okay then. Let’s start with some Physics! Tell me what experiments you’ve done in your physics lab?Me: We’ve done um… an experiment to test how the time period of a simple pendulum varies with length…P1: Alright! You are given a pendulum whose bob is a hollow metal sphere filled with water. Unfortunately, a small leak develops and the water level in the bob gradually decreases. How would the time period of oscillation vary?Me: Okay, suppose we take this pendulum and set it into oscillation by giving it a small displacement…P3: How small should this displacement be?Me: Well, in the lab we’re told to use an amplitude of 15°…(They all start laughing)Me: We need the pendulum to execute SHM. No, it’s not really SHM; it’s angular SHM. So the torque experienced by the bob should be proportional to its angular displacement from the mean position. In the calculations, we use that fact that [math] \lim_{\theta \to 0} \dfrac{\sin \theta}{\theta} = 1 [/math]. So the amplitude should be pretty small.P3 (smiling): Alright, go on.(I wrote [math]T=2\pi \sqrt{\dfrac{l}{g}}[/math] onto the white board and started explaining how the effective length of the pendulum would first increase and then decrease back to the initial length. So the time period would increase and then decrease back to the initial time period. I said along the way that the center of mass of the bob would be at the center of the sphere both at the initial and final states.)P3: How do you know that the center of mass of the (filled or empty) bob is at its center?Me: Well, the easiest way to see it is by symmetry. You could also…P2 (smiling): Yeah, that’s fine. Have you heard about the Foucalt Pendulum?Me: No, I haven’t (nervous chuckle).P2: That’s okay. I’ll tell you. It’s an experiment can be conducted to measure the rate at which the Earth rotates if you know what latitude your at. Alternatively, you can use it to find out what latitude you’re at if you know the rate of rotation of the Earth.Me: Oh, cool. (or something to that effect)P2: Suppose you place a pendulum at the North Pole and let it oscillate. What happens to the plane of oscillation as you let it oscillate for a while?Me: Hmm… Well, the Earth rotates. So it’s a non-inertial reference frame. So the bob would experience a pseudoforce and the torque due to the pseuodoforce would cause it’s plane to um… I think the plane would gradually rotate (with respect to and observer on the Earth).P2 (smiling): That’s absolutely right! Now through what angle would the plane of oscillation rotate during the course of 24 hours?Me: The orientation of the plane of oscillation would actually be the same throughout. It’s the Earth underneath that’s rotating. Since the Earth completes one rotation in 24 hours, I think it would complete one whole rotation, ie 360°.P2 (smiling even more): Absolutely! Now what happens when you place this pendulum at the equator.Me: I’m not very sure but I don’t think the plane of oscillation will rotate in the that case.P2 (smiling EVEN more): You’re perfectly right! That’s essentially how they measure the latitude using the Foucault pendulum. Do you know what that pseudoforce is called?Me: Well, in geography, we’ve learnt about the Coriolis force which deflects winds and stuff. It’s probably the same thing.P3 (smiling): That’s right.P1: That’s more than enough physics. Let’s try some math.M: Are you familiar with quadratic equations?P2 (suddenly pipes up): I know a nice QE question? Can I ask one?M: SureP2: Suppose you have a rectangle whose perimeter is 100 units. What’s the maximum possible area it could have?(I’m surprised that he asked such a simple question since KVPY math has a reputation for being hard)Me: I think we can um… Yeah, we can apply the AM-GM inequality on the length and the breadth.(Working it out on the whiteboard, I find the the maximum area is 625 square units)P3: Correct, but do you know for what dimensions this area will be achieved?Me: We can work that out but using the conditions [math] l + b = 50 [/math] and [math] lb= 625 [/math]P3: Yeah but you just used the AM-GM inequality. Can’t you tell me what the dimensions would be directly?Me: Oh yeah! It’s the equality case of the AM-GM inequality! The length and breadth should be equal. So that’ll come out to a square of side length 25 units.P3 (smiling): That’s right.M: Are you familiar with vectors?Me: Not in very much detail but we’ve done the basics in physics.M: That’ll do. Can you derive the condition a test vector has to satisfy to be tangential to the family of vectors whose magnitude is [math] r [/math]?(I take a minute to comprehend the question and proceed)Me: So, we basically need the condition the test vector has to satisfy to be tangential to a circle at the origin of radius [math] r [/math]. But um… by the invariance principle of vectors, you can translate around any vector without changing it. So you can translate any vector to be tangential to that circle.M: That’s okay but suppose the test vector is tangential to the circle at a vector [math] \vec{x} [/math]. What condition would the test vector have to satisfy?Me: Since they’re perpendicular to each other, or orthogonal as I think they’re called when it comes to vectors, their dot product must be zero. So [math] \vec{x} \cdot \vec{t} = 0 [/math].M: Good. 25 minutes are up. I think you can go. Thank you.Me: Thank you.I came out not being able to believe that it went so well! They didn’t even ask me any chemistry or biology!The thing that struck me the most was how friendly and enthusiastic they were. I was expecting a group of wise old, stern professors but they were all very pleasant and polite people.The results came out yesterday. I scored 93.86 in the interview and qualified with AIR 108. :)

Let’s break this question down by it’s parts, shall we?“I’m a diagnosed psychopath”According to your profile you are thirteen;Abdulraheem GadStudent in VISS, Lives in Dubai, talks Russian, Arabic & engI am a student currently in grade 9, 13 years old and I live in Dubai.You are not a diagnosed anything at this stage, as ASPDs minimum diagnostic age is eighteen, and psychopathy cannot be considered until the brain is done growing at twenty-five.my parents don’t knowIf you were diagnosed with anything like the precursors to ASPD, they would.I manipulate people.Welcome to being human, but specifically, welcome to being thirteen.Am I a bad person?See, now, a psychopath wouldn’t ask this. I am a psychopath, my parents don’t know, I do manipulate people, and I would never question my value as a person. That’s not how psychopathy works.I have gone into detail about why psychopathy cannot be considered until twenty-five, and why teenagers need to be more informed about the growth of the brain. it would answer a lot of questions, and prevent them from self diagnosing things on the internet. Here is that information;Athena Walker's answer to Why is autism diagnosed in children but not psychopathy when so many behaviours are similar/can be observed in childhood?This is due to brain development. Psychopathy is a variant brain structure.The brain forms back to front. The back of the brain matures first; the front finishes around the time you hit that magic number that also allows you to rent a car. Until the front of the brain finishes growing, you can see narcissistic, psychopathic, and callous behavior. None of it means anything at that age.The last aspect to develop is also the part of the brain that deals with consequences of your actions. Without that in place, people can behave in very impulsive ways. That, as well as behavior laced with several aspects of narcissism, is just part of being young. These traits can easily be mistaken for ASPD or psychopathic traits.This, however, means the opposite of what you assume. It means the brain of the psychopath will be psychopathic. You cannot change that; nothing fixes that. What you cannot do is determine psychopathic brains from a normal brain until both brains have completed growth.When the brains of both are mature, that is when the differences are observable. Until that point, you can easily mistake a developing neurotypical brain or its behavior as psychopathic, as due to the lack of neural maturity, their brains can both look psychopathic in a scanner, and their behavior can appear psychopathic when it is just a child or teenager working within the wiring that they currently have.People have made the argument that some people have fully mature brains by the they are eighteen, however this does not make psychopathy determinable at that age, or younger. For the vast majority of people their brain finishes maturing in their mid twenties.James Fallon is a neuroscientist. In being such, he obviously has a great deal of knowledge behind the brain, its development, and when it is ready for certain actions. One that he mentions is war and when we should be sending people into battles neurologically. He makes that argument that due to the level of development of the brain in these years, the earliest that a person should be sent into war is twenty-two. In his book The Psychopath Inside that was published in 2013, he states;Stressful stretches of a young person’s life such as college, first marriage, and especially military combat couldn’t come at a worse time for the developing prefrontal cortex.This is a big deal for the armed forces. A freshman and a senior in college are very different human beings. Sending kids to war at eighteen is ridiculous, as they’re still in the active state of frontal lobe development. The military uses psychological tests to make sure recruits aren’t crazy, but that won’t tell you how they’ll be in two years. If we’re going to have war, we shouldn’t let soldiers fight until they’re twenty-two or twenty-three.His statement about a college freshman and senior is absolutely on point, now let’s bring into the mix a child and their developmental processes. With their brains being significantly lower in development, it would be impossible to determine psychopathy in them. However trying to label them can have life long impacts. I had an excellent example of this recently in a comment thread.Michelle MooreAug 5 · 1 upvote from Athena WalkerMy brother was diagnosed as being psychopathic when he was five years old. I’ve no doubt that my mother’s attempts to explain it to him (and the rest of the family) considerably hindered his development into a decent human being, as if being psychopathic was somehow a ticket to wilful anarchy and cruelty, ‘because he couldn’t help it.’I still don’t understand it (I was only a year older than him, so reliant on the information I was given, until I decided I didn’t want to be around him any more), but being able to read your responses to questions on the topic really help. Thank you.Athena WalkerAug 5 · 1 upvote from Michelle MooreWow, whoever diagnosed him as psychopathic at five needs to have their license revoked. There is no way to make that determination in a five year old, you can’t until twenty years hence, and it labels a child in the parents’ minds. It’s a ridiculous move on their part. That’s really unfortunate for your brother.The results are partially why you never make that kind of diagnosis in a child. Unless he had a brain scan now to show that he is indeed psychopathic, assuming that he is finally twenty-five, it is far more likely that the label determined his fate. He saw no reason to try because “he’s a psychopath”. He’s just doing what’s in his nature to do in his mind. I can imagine that it is an inescapable self fulfilling prophecy.You’re welcome for the writings. It’s unfortunate that the reason you found them is the situation that you described.Michelle MooreAug 7 · 1 upvote from Athena WalkerThank you. He’s now 53, although I haven’t seen him for about twenty years (safer that way). I think you’re right - it was indeed a self-fulfilling prophecy. But if this exchange helps even one family to think more deeply or differently about such diagnoses / issues affecting them, that’s something good to come out of it.Athena WalkerAug 7That would be an excellent outcome, I agreeThis is a prime example of an entire family being affected by this diagnosis. What did that ultimately determine? That he was psychopathic? No one knows, but it certainly gave him the ability to decide that he didn’t need to require of himself. He could behave however he wanted because he was a psychopath. The chances that a child is psychopathic is less than one percent. However, labeling a child with that sort of diagnosis is pretty much is limiting a child to assumptions.A child that is psychopathic can be helped in terms of understanding the world and their interaction with it, but the label of psychopathy is not necessary to do this, and if anything it is harmful to the development of the mental faculties of that child.A cooperative project at MIT is dedicated to examining the brains of young people and their development, the link can be found below. It is a project with over five hundred reference materials, and is being conducted by one of the most respected and advanced universities in the world. They state the following;Responding to increasing awareness and concerns, the MIT Young Adult Development Project was created in 2005 to analyze, distill, and disseminate key findings about young adult development, findings that shed light on the unique strengths and dramatic challenges for this extraordinary period.Defining young adulthood as the years between 18 and 25, the project focused on identifying research conclusions about which there is widespread agreement across disciplines and researchers, as well as practical relevance for universities, employers, parents, human service practitioners, and young adults themselves.Their determination thus far;Prefrontal cortex: The most widely studied changes in young adulthood are in the prefrontal cortex, the area behind the forehead associated with planning, problem-solving, and related tasks. At least two things affect the efficiency in its functioning:myelination: the nerve fibers are more extensively covered with myelin, a substance that insulates them so that signals can be transmitted more efficiently, andsynaptic pruning: the "briar patch" of connections resulting from nerve growth are pruned back, allowing the remaining ones to transmit signals more efficiently.Connections among regions: At the same time, the prefrontal cortex communicates more fully and effectively with other parts of the brain, including those that are particularly associated with emotion and impulses, so that all areas of the brain can be better involved in planning and problem-solving."Executive suite": The cluster of functions that center in the prefrontal cortex is sometimes called the "executive suite," including calibration of risk and reward, problem-solving, prioritizing, thinking ahead, self-evaluation, long-term planning, and regulation of emotion. (See Merlin Donald, Daniel Keating, and others in References.) It is not that these tasks cannot be done before young adulthood, but rather that it takes less effort, and hence is more likely to happen.20s and beyondAccording to recent findings, the human brain does not reach full maturity until at least the mid-20s. (See J. Giedd in References.) The specific changes that follow young adulthood are not yet well studied, but it is known that they involve increased myelination and continued adding and pruning of neurons. As a number of researchers have put it, "the rental car companies have it right." The brain isn't fully mature at 16, when we are allowed to drive, or at 18, when we are allowed to vote, or at 21, when we are allowed to drink, but closer to 25, when we are allowed to rent a car.This is why psychopathy is never determined in children, and why it also should not be determined until after that person’s brain is fully mature, This will not happen until that person is in their mid twenties on average. Thus diagnosis of psychopathy (which is not actually diagnosed anyway) can not be made in children. It would be wildly inappropriate to do so.If you are worried about being a bad person, here is an easy step by step guide to being a good one.Step one. Identify where in your life you are partaking in questionable behavior.Step two. Knock it off, and find something productive to do with your time.Step three. Refer back to steps one and two.That is all.Behavior is a choice. If you are worried yours is making you a de facto bad person, change it to something that doesn’t give rise to that concern.Athena Walker's answer to If a person is born a Psychopath then why do doctors say they cannot diagnose a Psychopath until adulthood?The Psychopath Inside: A Neuroscientist's Personal Journey into the Dark Side of the Brain: James Fallon: 9781591846000: Amazon.com: BooksYoung Adult Development Project

Schools serve many purposes from building self-esteem to teaching children the importance of teamwork and collaborating with others. Schools guide youngsters based on the regular routine which is the most important as we direct them to the workplace where they become the purposeful member of society. Along with the advancements in technology where everything is preferred to be digitized, the educational apps for high school are one of the most beneficial advancements in the present world of education.Over the past three to five years we have seen interest in mobile devices as learning tools grow exponentially. What was once a counterintuitive curiosity is now the subject of serious?Evaluation by an ever-increasing population of school districts. And yet there are still significant and contentious questions about mobile learning implementation that are being debated without many clear data or classroom-based experience. These questions include whether handheld and tablet form factors are adequate for student production of content, or just consumption and whether Android or iOS devices are more appropriate for school implementations.We know that when students are more engaged, they are more motivated, and they perform better. With so many amazing education apps available and more being developed all the time, there’s no limit to the exciting possibilities for learning. Children’s apps are an interesting way to go when it comes to teaching toddlers about some difficult topics.They can browse an interactive periodic table of elements. They can even dissect a virtual frog in one class, then flip through the world’s greatest collection of art in the next. And teachers can deliver engaging lessons, monitor progress, get immediate feedback on students, and stay organized.Apps can incorporate many types of interactive features that may or may not enhance learning.Through interactive experiments, Interactive features not only engage students but also demonstrate concepts and enhance learning in ways that traditional methods can’t.It’s an exciting time of innovation in learning. We’re seeing apps that provide engaging, Multi-Touch, rich experiences that were never before possible. Have fun exploring the amazing world of education apps.Anything which is based on the current technology that can be either an educational app or game is bound to attract the young generation. Since there is a difference between the way we think and students’ mentality, most of the students tend to like and find educational apps to be more efficient and useful. School apps are made by keeping student’s interest as the primary concern along with the level of understanding.App for schools is a great step to draw the student’s interest in studies and provide different options in the future. These apps are not less than a bridge to make them purposeful citizens of the society and global development of the nation. There can be some beliefs that this kind of advancement may cut the value of classroom teaching, but what the future generation needs to hold the major priority for the present scenario. The apps for school are not just made for students, but even teachers and management can take an active role and explore towards means of teaching and self-learning.What Byju’s Provide?Byju’s app is an educational app for school students along with competitive exams like GRE, GMAT, JEE & CAT. The app provides animated video lessons for class 6 to 12 CBSE and ICSE board. Students can access any topic under Physics, Chemistry, and Biology along with Mathematics problems, derivations, and NCERT solutions. Lower-class students can build a strong foundation in all the subjects by watching interactive YouTube videos that provide complete information about the concept and are explained in detail along with interesting games, puzzles, quiz and a lot more. For the higher grade students, previous year question papers solved NCERT solutions, and other model question papers are available for them to practice and prepare for their board and other competitive exams.
