In the age of the internet, what to memorize and what not?

There is a heated discussion about why remember facts when all information is at fingertips (through the internet)?.
So first look at dictionary what a fact is?
The first definition that comes up is this:
A thing that is known or proved to be true.

Ok, but most things we study in our education are facts.
Earth revolves around the sun is a fact.
New Delhi is the capital of India is a fact.
Hitler born on dated 20 April 1889 is a fact.
Independence day of India is 15th August is a fact.

Out of these, first two and last one, I needn't have to search the internet,  because these facts are very important to me as I live in India, and I am from Earth (Lol). I searched the internet to find out when Hilter was born because his date of birth was irrelevant for me till now. Maybe I will forget his date of birth after one day because it will not come to any use to me later.

So, some facts are very important to memorize while others are not.  Then what to memorize and what not? In the age of the internet, not only all information are in fingertips, but also the humongous amount of facts.
Can we remember all these facts? Of course not, we have a limited amount of memory to store. Brain capacity is limited.

So, it's important to choose what to keep it in memory and what not?

We needn't have to memorize:
Non-concrete information that takes a huge amount of effort and time to memorize, which we don't use often or will not use often in future, can be extracted or processed by the Internet or other efficient tools.

What is non-concrete information?
Why we face difficulty to remember non-concrete information?


For a 5 year kid, A-Z alphabets is a non-concrete information but do (s)he needs to memorize it. Yes, because, alphabets are something that she will use it often, every time. So is true for multiplication table.
But do the kid has to learn 34 multiplication table? Why not? Even that is useful.
Because it will take too much of effort to memorize so much of multiplication tables. If we give all this burden, he will only learn tables and nothing else in life.

We do specialization instead of learning everything because we can't be a jack of all trades.
We have to skip learning something to learn something, as we have a limited amount of memory storage and time.

If you spend all time in memorizing shortcut formulas of physics, when will you strategize to solve the problems? Formulas are easily available on the internet or book, but learning how to use it more important than memorizing it.

So, we need to prioritize what to memorize and what not as we have limited time and memory.


Getting the job done that is useful is important, whether you have done it through mental computation, or through a computer doesn't matter. Yes, making computer to do things does require some mental work and prior knowledge that is stored in our memory.

Critical Analysis on NEET Biology Questions, comparison with Campbell Biology Questions

Image
All entrance exams only test rote memorization of abstract concepts without testing critical thinking and in-depth knowledge. Questions don't let you think, just requires a recall of abstract data that you have memorized. Today I will review few questions of NEET and compare those questions with Campbell book Look at the question, it's very descriptive, and promotes critical thinking, just reading the question itself makes you think even if you don't know the answer But what NEET will ask The equivalent of a structural gene is: 1) Operon 2) Recon 3) Muton 4) Cistron Believe me, students would have just memorized or linked structural gene with cistron by attempting previous years questions. The questions simply don't make you think. Do the questions address the answer to the question why Cistron is called a structural gene? From the internet: A structural gene is a gene that codes for any RNA or protein product other than a regulatory fact

The Competitive Collaboration Algorithm

Image
Competitive Collaboration Algorithm: It's a decentralized network where you compete to collaborate. Edge weight represents difficulty to get connected. Difficulty depends on factors such as distance, location, quality, price. We need to choose subgraph containing all the required nodes (e.g. nodes containing a,b,c,d ) that has a minimum weight or optimal weight. a,b,c,d can represent different services, whereas a1, a2 represents the same services from a different service provider. For example, 'a' can represent a student, 'b' can represent a teacher, 'c' can represent content provider such as a biology textbook and 'd' can represent a classroom or building. Similarly  'b1' represents teacher1, 'b2' represents teacher2, etc. So, For student1 (a1), the optimum subgraph or subgraph with minimum weight containing all the required services are a1,b1,c2, d2 with weight 0.5+2.3+4.2 .

Personalized learning goals: New information is built over reusing of previous information

Image
Some students perform better, while others not. What are the main reasons? 1) Study material provided and learning strategies used by teachers. It simply doesn't meet the learning criteria. https://github.com/amiyatulu/teacher_resources Students are feed with so much of abstract stuff as a result only those students excel who have a better memory retention capacity of abstract information and those who work too hard for it. But such a hard work is meaningless, as you will forget such information after exams are over. 2) Not teaching kids from where they are.  I will explain it with a concrete example. While teaching chemistry, one of my students was so fast in holding information and doing the problems, while other was slow. The reason for her/his slowness is not that he/she is less intelligent, it's because (s)he is taking more time for processing due to lack of previous foundational information.  When (s)he does the processing, (s)he has to take the account of

Explaining true experiment to a 13-year-old

Let's start with a Twitter Joke: Conversation over breakfast. ME: Whoa, you lost another tooth? A: Yes! ME: Why didn't you tell me? A: I'm conducting an experiment. If I lose a tooth and don't tell anyone, will the tooth fairy still come? If not, then I know the tooth fairy isn't real. ME: ... HUSBAND: 😮 A small introduction to true experiments True experiments involve changing one variable and then measuring another. A variable is any factor, trait, or condition that can exist in differing amounts or types. The two main variables in an experiment are the independent and dependent variable. An independent variable is a variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is a variable being tested and measured in a scientific experiment. Independent variable: Cause Dependent variable: Effect The researcher is looking for the possible effect on the dependent vari

What are the problems with grades?

Image
The problem with grades: 1) Grades are an oversimplification of achievements that say very little about it. They are just numbers which say nothing about what you know or about your working skills. 2) Grades are often biased and are done based upon the context of questions . Sometimes questions are not well made, most often they are just repeats of previous year questions. Because of this they really don't check the critical high order thinking of the children. 3) Malpractice . It is also rampant in our education system. 4) Too much of psychological pressure from parents, teachers to score more, that leads them to depression and sometimes even they take drastic steps like suicide. 5)Grades shift the goal from learning to just marks , which can be achieved by many many means with our inefficient education system. 6) No grades are given for effort , grades are given only for solving hypothetical book problems . I have seen many students struggling in our education syste

How MOOCs + Open Lab can rescue our education system?

MOOCs (Massive Open Online Courses) are most affordable (even free), but the problem with it is practicals. Can a student earn a degree in subjects like Mechanical Engineering, Aeronautical Engineering, Biotechnology or any other subjects that require expensive practical equipment with doing MOOCs? It's not possible because there is no way to do practical experiments. So along with MOOCs, our education system should provide Open Laboratories What Features Should Open Laboratory have:  First, it can be opened by anyone after getting approval from the government. Open Laboratories can buy cutting-edge equipment based on the technology that is required in different courses. Open Laboratories should have the freedom to buy based on how much they want to spend. They need not have to buy all the equipment, just like colleges. This will cut the expenses of open laboratories. It will also promote entrepreneurship. They should have qualified researchers or teachers who know the worki

Steps that can be taken to improve education system

1) MOOCs for Teacher: Every body cares about student education, but no body thinks about teachers. They can only transfer knowledge only if they themselves are well educated with the subjects and knows how to teach scientifically so that the teaching is most productive and knowledge reaches to maximum students. Like students, teachers should also be motivated daily. So there should be 1 hour MOOCs for teachers even, where they can listen the lectures and appear exams. 2) Including courses like Learning How to Learn ( Page on coursera.org ) and Becoming a Resilient Person ( edX ) and many other study techniques in the syllabus itself. So that students knows how he should study productively without rote learning the things and also learn to cope up with the stress. 3) MOOCs for Students: In the first phase for about 6 months we should give MOOCs for teachers, than when they are well versed with all the computer technologies, than time for MOOCs for students. But computer (e.g.  cheape

Why we face difficulty to remember non-concrete information?

Image
What are the functions of a brain? Pattern recognition, interpretation and storing of information that we get from our sense organs I would go with following steps to show that non-concrete information is the type of information that our brain is not trained for. The most requirement to remember abstract information is more recent when mathematics and different languages were invented. The invention of writing that allowed storing information that we can't remember. The human being invented abstract information like more than one language or mathematics which we are evolutionarily unfit to remember. Are we evolutionary unfit to memorize abstract information? To prove it lets look the following experiment. The brain is good at recognizing things in a span of seconds. For example, we change our path if there is a hindrance in front. But if you close your eyes, we will miss details of the hindrance. Let's try to memorize this map in a span of se

What happens when you limit the voicing of these two important words? 1) Nescience : (Ignorance is a lack of knowledge) Our eyes and senses are limited by many ways. We are adapted to view the world perfectly only at a particular zooming level . The world becomes blurred when we increase or decrease the zooming level. We can't know what is happening in another country just by our senses. Increasing and decreasing the zooming level requires indirect measurements that are tedious and sophisticated. You need to learn the outcomes of the research, and techniques to make measurements by bringing it down to texts and tools that are compatible with our zooming level.
