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

By Amiya Behera April 24, 2016

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 in others. Why force them to score best in everything and give them a lot of burdens? A student who scores O in some subjects and B in others is more disciplined and focused. Why we always hunt for the genius who should be good at everything.

We should reward students for bringing solutions rather than securing marks or preparing for exams.

The Competitive Collaboration Algorithm

By Amiya Behera October 02, 2018

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 .

Usefulness of the model:
1) Prediction: One can make a pred…

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

By Amiya Behera February 18, 2017

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 many kinds of st…

Higher education must immediately stop obsolete blackboard teaching.

By Amiya Behera December 22, 2017

Higher education must immediately stop obsolete blackboard teaching. Higher ed requires mentor and collaboration.

What is obsolete blackboard teaching?
[Lecturing is the] best way to get information from teacher’s notebook (mouth)
to student’s notebook without touching the student’s mind. — George Leonard Patterns for bad practices of teaching, what is done in higher education, even best colleges.
https://iambrainstorming.blogspot.in/2017/11/patterns-for-bad-practices-of-teaching.html

So, how this can be solved?
This is how colleges must run when there is the shortage of skilled teachers:
1) Give students compilation of pedagogically right content (such as videos, MOOCs, books, magazines etc.)
What it means to be pedagogically right content?

Bacteria and Competition: How it's similar to human? and Why we should have family planning?

By Amiya Behera September 22, 2016

Growth of the bacteria refers to an increase in bacterial numbers
When bacteria is grown in a liquid nutrient medium, the population is counted at many time intervals, and we get a bacterial growth curve that represents growth of cells over time.

Why bacterial growth curve is so important?
It gives the idea to learn about the impact of competition in the simplest way. It gives the answer what happens to a population when resources are limited.

Bacterial growth best suits even to describe the human population.
In science, there are 4 phases, but for simplistic understanding, without any scientific jargon it can be three stages: Thrive, Survive, and Deteriorate

Stage 1: Thrive
In this phase bacteria has sufficient resources, so bacteria flourish, prosper or grow vigorously.

In science, it's the lag phase and log phase.

In the lag phase, there is no cell division, but cells are not dormant, they undergo intense metabolic activity, synthesizing enzymes and various molecules
In log phase…

How much does retrieval practice help in learning?

By Amiya Behera February 26, 2019

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.

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 research from online article or …

Why we face difficulty to remember non-concrete information?

By Amiya Behera March 08, 2017

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 seconds or minutes. Can you do it?

Apps can solve the basic social security problem

By Amiya Behera August 13, 2018

The public distribution system is inefficient in terms of production, distribution, and consumption of goods and services and lacks inclusiveness.

You can view the fallouts of PDS:
https://en.wikipedia.org/wiki/Public_distribution_system

Apps can solve the basic social security problem, bring healthy habits of spending money and can be used to run experiments, test it and improve it to get the best results.
Features:
1) API endpoints that any app developer can use and integrate it with their e-commerce apps. Separate types of account for seller and customer.
2) Statistics about how you spending money. General statistics should be publicly available, where experts can review, critic and improve the results.
3) Tagged money, which means you can buy only particular types of products with that money.
e.g. Tagged money for grocery, or tagged money for cooked food, or tagged money for education which gets transferred to the seller in untagged form. Possibilities are limitless.
4) Tagg…

Probability distribution of marks should not be normal.

By Amiya Behera April 14, 2017

What type of variable is the mark, discrete or continuous?
Marks is a discrete random variable that has a finite number of values or a countable number of values.

A continuous random variable has infinitely many values, and those values can be associated with measurements on a continuous scale in such a way that there are no gaps or interruptions.

Requirements for a Probability Distribution
1. ΣP(x) = 1 where x assumes all possible values of marks
2. 0 ≤ P(x) ≤ 1 for every individual value of x

For example, 2000 students gave exams with full marks of 10, the probability distribution of marks to have a normal like curve will have following frequency distribution given in the table.

Marks xFrequency fProbability P(X=x)040.0021230.01152990.049532270.113543990.199554970.248563900.19572510.12558840.0429220.0111040.002

Importance of educational videos and solving its limitation by teachers assistance

By Amiya Behera August 25, 2017

Many technologies have promised to revolutionize education, but so far none has. With that in mind, what could revolutionize education?

Why educational videos don't work?
1) Procrastination: Educational videos give freedom of anytime learning, but this can lead to procrastination. According to Parkinson's Law: "Work expands to fill the time available for its completion". But in case of video lectures or MOOCs there is no limit of time, so usually, we procrastinate. Limiting time to complete the MOOCs is also a bad idea, as it takes away its advantage of any time and anywhere learning.
2) Lack of a social interaction: We share emotions, feelings, discuss with the teacher, friends that come to our mind just like a true social animal and classroom brings a social two-way interaction, but it doesn't happen in case of MOOCs.
3) Answerability: No one is there to keep you accountable for finishing the course, no outward push, everything lies with intrinsic motivation or …
