If all scientific discovery relies on peer review for validation, why not assessment be done through peer review?

All scientific discovery relies on peer review for validation,
Why not the assessment of schools and colleges be done through peer review?


Peer Review definition:
evaluation of scientific, academic, or professional work by others working in the same field.

In case of open peer review, the reviewer reports are published which can again go through auditing.

Benefits of open peer review:
1) Feedback to the students
After a test, feedback to the student becomes a crucial part of their learning. Feedback can be in many forms such as detailed corrections of the answers, making their misconceptions corrected for a particular concept, identifying their specific problems and asking them to take necessary steps to improve.
2) Time-saving of teachers
As this can be done in a collaborative manner, it will give freedom to any teacher from the respective subjects to annotate the assessments, the burden is no more to the individual teacher, it will be shared among the country or world. The burden of evaluation is not only shared among teachers but also computer by different statistical packages.
3) Microscopic analysis
Imagine how hectic the evaluation of assessment is by an individual teacher for a class of 50 students. Because of it, teachers are bound to miss the details of the problems of students. But this no more a problem with open peer review, due to shared work. If you have not identified the problem, it's more likely that someone else will identify it and address it.
4) Authenticity
Open peer review makes assessment most authentic, accurate and unbiased. Prejudice of teacher can be easily identified and corrected by experts.
5) Easy citation
Feedback to the students can be evidence-based, and useful research articles can be cited to back the feedback. It will help them to distinguish between facts and myths.
6) Earning microcredits
Students no longer have to study for obtuse macroscopic grades, they have to study to reach their learning goals. Education will be more personalized, students can earn credits to reach each learning goal.
A proper algorithm is required to be free from spammers and inapposite posts to gain incentives, that nullify the effect of Campbell's Law.

"The more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor."
https://en.wikipedia.org/wiki/Campbell%27s_law


7) Diversity in learning
Students can learn topics that are unimaginable now because of strict syllabus system. Be it social justice for science students, cutting-edge technology of economics such as blockchain or logical fallacy of philosophy. Students can do projects as they like that solves real problem. For each one, they can earn microcredits.
8) Easy recruitment
As the data of assessment are easily available, recruiter can choose and hire the right candidate with ease based upon their real project works.

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 su

Explaining true experiment to a 13-year-old

Image
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

Universal Basic Income and Education: A beginning to a continued resilient human ecosystem

Image
Universal Basic Income is a welfare regime in which all citizens (or permanent residents) of a country receive a regular, liveable and unconditional sum of money, from the government. The central claim that UBI tries to solve is the end of poverty and financial insecurity by the indsicriminatory supply of free money which can be exchanged to buy your basic need requirements. But the problem lies with execution and design that nullify the damaging possibilities speculated by the critics. Speculation: It disincentivizes people to work, so can create an adverse condition for wealth creation. A proposed elaborative solution: Morally, the basic required need for survival such as food, clothing, shelter are not incentives. Its a fundamental right of the people. But biologically, these are the incentives to pacify our hunger or appetite. Food, clothing, shelter are basic needs for survival, but we need lot more for thriving. One of the essentials to thrive is education that nouris

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. Without sharing these texts, using and adapting it, our knowledge will be limited to our zooming

How making an aahaar api can revolutionize India in providing personalized and accurate information?

Every citizen of India has Unique Identification Number: Aadhaar. Many websites in health care, railways and almost all sites use your personal details. But the problem is, some times these personal details can be inaccurate. There can be many reasons for it. e.g. Storing the birth data of child in eMunicipality portal: The nurse writes about Mother and Father details in a form. From between writing the form to feeding it into the eMunicipality portal, there are lots of chances of feeding wrong data. Some of the reasons are: 1) Listening error of nurse, so the nurse write the wrong information 2) Laziness and lack of time for nurse to fill all the fields on the paper form 3) Spelling errors of name and address details. 4) Person who is doing data entry in eMunicipality portal unable to recognize the handwriting (as we all know doctors write in horrible handwriting, which an expert can only read) 5) Person who is doing data entry, fills the compulsory field with arbitrary dat

Aadhaar: It's time to encrypt all biometric data with password

All biometric data should be encrypted. During authentication, the user needs to provide both aadhar number and password. So only the user can decrypt and access the biometric data. Biometrics of the little finger can be kept in the unencrypted form, to remove duplicates. In case you forget the password: One has to submit the aadhaar number and little finger biometrics to obtain another. The ciphertext of aadhaar number should be replaced with new ciphertext (obtained from new password) In case you lost both (Password and Aadhaar Number): The person must come under scrutiny and old aadhaar number should be removed by using his/her little finger, and new aadhaar number can be given. To change the password: Enter the old password and aadhaar number, match the ciphertext with your fingerprint and then replace the ciphertext with new password. All the steps should be done in aadhaar center. The python code: from Crypto.Cipher import AES obj = AES.new('Aadhaar No:123

How much does retrieval practice help in learning?

Image
Students do forget things, we measure the effectiveness of the retrieval practice based upon how much they have remembered it.  But forgetting doesn't mean that students have unlearned what they have learned. Neither learning means remembering things. Paul Hewitt Physics Yes, the best strategy to get a high score is retrieval practice. But high score relies on the ability to recall things, not test the actual learning. We need not have to do retrieval practice to do programming,  just re-reading and using the code is enough. The best way to learn to program is to use and apply it the hard way. The more you use it and apply better strategies, the more better your programming skill will be. The same principle applies to all subjects, whether its maths, physics, biology or philosophy. What is required is understanding of the subject, through strategies like the Feynman Technique. Understanding creates an index in your brain, which later can be used to retrieve the whole

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
