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

Image
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 ag...

Allowing mediocre colleges to provide degree certificate is degrading the education system

IITians, doctors, and most desired teachers try to join coaching institute instead of colleges. Reason: If you run a coaching institute, teachers are heavily paid, because about 70-80% of students money goes into the pocket of teachers, but no matter how much students pay to college, teachers are given fixed and very low salary. Also, brilliant students don't aim to join as a teacher, as pay scale is too low. Coaching institute business model works best to provide quality education as teachers have the complete sole responsibility about their amount of income and autonomy to provide quality. If teachers don't perform well, their pay scale will be low, so it creates a subconscious pressure to compete for quality . But this doesn't happen in schools or colleges. How allowing mediocre colleges to provide degree certification creates a problem? Allowing them to provide certificate enables them to bring students despite not providing quality.

Suggestions for changes in lessons of NCERT Chemistry book

Image
Chemistry Book: NCERT Chemistry book requires a complete reinvention, with eliminating most units that are unrequired at the higher secondary level and making it more systematic with the flow of information and building new connections by using prior information. e.g. How quantum mechanical model is linked with explaining the properties of elements and molecules? And before explaining the quantum mechanical model, it's needed to explain what are model and theories. From Britannica: Scientific modeling, the generation of a physical, conceptual, or mathematical representation of a real phenomenon that is difficult to observe directly. Scientific models are  used to explain and predict the behavior of real objects  or systems and are used in a variety of scientific disciplines. The Higher secondary level is meant to know the basics first with the foundational understanding of the mechanism of concepts in detail. It should be relevant to students day to day life to know their surr...

Experimental manipulation after tests using eSALT feedback from students

Image
Personalized pre and post test need to be conducted in the following manner with experimental manipulation: While giving questions, each student needs to be asked for how easy or difficult the questions are. Student Feedback for Questions Ease ( eSALT ): 1) Easy (E) 2) Safe (S) 3) Average (A) 4) Low (L) 5) Trouble (T) Also, keep space for some specific feedback that students want to comment on the question while answering. (e.g. Mistakes in questions, concept not taught in the class, or not understood, unable to recall or don't know the answers or specific part of answers like formula or for example atomic number of element, unable to understand the question). Ask students to be elaborative and be particular to the problem faced while writing feedback. Students can give not so useful feedback in order to hide their problem, so teachers should be make them feel safe so that they can express themselves. Teachers curation 1) Students making mistakes with Questions tagged Easy, Safe,...

Why convert everything to rat race?

Image
Instead of having cut off marks based on students scoring, we can have minimum high pass marks that check if the student has enough knowledge to study medical including checking the projects they have done (it checks whether the student is exceptionally excellent for the work). Then  lottery system can be done if we have a fewer number of seats. The proposal can also include girls and other vulnerable social class under reservation. This will reduce the too much of unnecessary burden on the student, also they needn't have to join coaching centers for getting the seats. No more sky touching marks, and no more importance of special coaching. Scientifically speaking luck do play a role in the entrance exam, it's not all about merit.  How luck plays the role? Students who score 2000 rank is not necessarily better than 3000 rank. Parents can't afford the coaching institute. Not knowing the pattern of exams, such as e.g. following Campbell book instead of NCERT, even though...

Why there is nature tendency to mix?

Openstax Chemistry Link to the book for image https://openstax.org/subjects/science If information is binary (e.g. 0,1) what is disorderliness (or entropy)? If two objects have similar properties or pattern, each object position is replaceable by the other object, is this the actual reason for spontaneous mixing or nature tendency to mix? Like dissolves like

NCERT books nothing more than short notes with giving too shallow knowledge

Comparative analysis of Openstax chemistry book and our NCERT chemistry book read by largest populated country Review of chapter Atoms, Molecules and Ions of Openstax and Structure of Atom in NCERT Openstax starts the chapter with a picture mass spectral analysis. Mass spectrometry is a very important technique to study atomic properties. To make you more curious it talks about the diagnosis of diseases through analysis of molecules in an exhaled breath. But ncert book image is this: NO IMAGE Let's come down to the introduction: NCERT Chemistry: The existence of atoms has been proposed since the time of early Indian and Greek philosophers (400 B.C.) who were of the view that atoms are the fundamental building blocks of matter. According to them, the continued subdivisions of matter would ultimately yield atoms which would not be further divisible. The word ‘atom’ has been derived from the Greek word ‘a-tomio’ which means ‘uncut-able’ or ‘non-divisible’. These earlier ideas were...
