How open review and data analysis of exam will change our education system?

As our education system is not transparent, and as we don't have the data, we are actually unable to find the problems, so unable to address them.

So what is an open review of an exam?

After the evaluation of answer script is completed, its scanned copy has to be uploaded to a website for public review. Also, analysis of the answers should be conducted, in which questions students are securing more marks, which questions are difficult to solve and students are not performing well in the questions. Complete statistical data should be produced, student wise, school wise, district wise and state wise.

What are the advantages?
It has no disadvantage.
With this procedure, we can address most of the problems in the exams. Schools and colleges will be more accountable, no malpractice will be there, students will know their fault, where they have scored less and where they have scored more, teachers will evaluate paper accurately

This should be done at every level of education, from class…

Good questions vs Bad questions: A critical Analysis

Let's analyze the questions given here about DNA:
http://blogs.biomedcentral.com/on-biology/2016/04/22/dna-day-quiz/

1. How many chromosome pairs make up the human genome
a) 23
b) 24
c) 12

One may argue this question is memory based, but it's not. It is one of the fundamental questions that a student has to memorize it.

After you have chosen to answer, its gives the feedback, why you are wrong or right. This is the most important step.

2. Your genes could influence your choice of partner, true or false?
a) True
b) False

Look at the question, even if you don't know the answer, the question makes you curious to know the answer. It gives us knowledge about whether gene influences your choice of partner or not. It is very related to our real life.

Again its give a feedback.
Genetic variation influences one’s choice of partner. The genetic correlation between height and the preference for a partner with similar height shows that genes affecting individual preferences for height …

Why India requires an archive for research articles to promote research and development?

Through Digital India initiative, India should consider a repository for research articles. This will promote permanent preservation of research articles.

India should promote research and experimentation is all fields, whether law reviews, science, economics, arts, and commerce, psychology, sports, Ayurveda, yoga, entertainment, music etc.

Students should be encouraged to design experiments and test the results and write articles in every field.

Higher education should be research based, where students have to produce genuine, original, quality articles. We should rethink our traditional exam oriented methods of education and allow students to explore with freedom rather than just learning the subjects for the exam.

Let student analyze, think critically and try to bring the solution to a problem. Why give them the burden of exams? Without freedom, one cannot search, scrutinize, inquire things. Give them freedom in what they are interested in. Let them score O in some subjects and B i…

Solution to improve colleges and Universities

Quora link: http://qr.ae/8njQdN

Students should be allowed to appear the entrance exam only once, in the same year after pass out from 12th.

If this is done, students would have not to waste their time for years only for preparing the entrance exam.

I have seen many students preparing for 5 to 6 years only to get qualified for medical entrance exam. Is  such an effort required?

We study to apply the knowledge, not to waste time for the entrance exam.

Why every student in India dream to study in IITs and IIMs, and Medical? Why not consider other colleges and universities? Why their condition is not improved? Percentage of  the students which qualify for entrance exam is not even 1%.  So why every student has to dream for IITs.

Here is a sure solution to improve other colleges and universities.

Just make a review team for questions paper that students appear in semester exams. Make the criteria that, they cannot set a question that favours rote learning. The questions should require cri…

Critical analysis of 12th Chemistry NCERT book

Image
Analysis of first 3 pages of Chapter 1:


1st Paragraph:
"The correlation between structure and properties helps in discovering new solid materials
with desired properties like high temperature superconductors, magnetic materials, biodegradable
polymers for packaging, biocompliant solids for surgical implants, etc."

The first paragraph itself start with the technical terms like biodegradable polymers for packaging, biocompliant solids for surgical implants. But the book does not explain what are these. How will a student imagine such technical terms and correlate with the structure of solids? Where are the solid structures of a biocompliant solids for surgical implants? And how structure suits the need for surgical implants.
Regarding magnetic materials, it's written at the end of the chapter. So at least say about it, that you will read about it soon

Another Paragraph:
Some glass objects from ancient civilisations are found to become milky in appearance because of some cr…

How Indian education system is producing parrots?

Please visit the biology questions of CHSE, Odisha. Even though the questions are old, the question pattern is not much different from this year.
https://drive.google.com/file/d/0B8x9dkicaW23akdvMWlSSElEOUk/view?usp=sharing

So lets, decode these questions. Almost 90% percent of questions are only memory based and very direct.
What is ozone shield?, what is BOD? and blah blah.

So do you think these questions can be answered a parrot, or a simple bot without any intelligence?
I think yes. Just teach each question to parrot for a week, it will able to answer the question.
Even our genius teachers in biology claim that they will give the selected questions, out of which about 70% of questions will come in the exam. So students have only to memorize the answers for a month before the exam and write the answers in the exam.

And this condition is not only for 12th class. It is same at every level of education, whether graduation or post graduation.

The solution:
Before, setting question, the …

How the concept of teacher : student ratio of 1:30 has loopholes?

After discussing with few teachers, I found that in some classes in some school, the number of students present is less than 30. In that case, a student doesn't get the subject teachers. How can in this principle, a student will get teachers for all the subjects. A math teacher can't teach physics. Also, there is disturbance with the number of classes. e.g. if the 5th class has 15 students and 6th class has 15 students, this leads to a shortage of teachers by half. So teachers have no option, left but to unite both the classes.
How can there be conduction of both the classes in one room?

So please update the rule, that for each batch or class there must be each teacher for each subject for a school, no matter how many students are there in the class.

Also, I found that in some govt. schools in Odisha, computers are given (3 to 4 months back) but no one is there to operate it and install the software. Why there is no computer teacher in all schools? The computer has become a ve…

Data-driven evidence based politics

How politician should work in India, in order to make the country successful?

Share you views at qoura: http://qr.ae/RLzCuX

Do political party work based upon their hypothesis, or use unbiased data to make decisions?

Recent data shows that, while voting for a particular party, people are more interested in the main leader (CM or PM) who will lead the state or country and does not much depend upon who are MLAs and MPs

But are political parties working in creating new leaders with value?
Most of the time, a party lose an election is due to lack of a proper competitive leader in opposition.
Proper examples would be Bihar, Odisha, West Bengal etc. Even though they are/were low-performing states, the opposition lost the election. Common people without political background does not even notice who were the leader in opposition. In Bihar, BJP tried to highlight Modi, but people are not giving votes to Modi, they are giving the vote to the state leader. So why don't the opposition spent …
