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: ...

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 variable that might be caused by c…

What if we limit the expression of these two important words: Share and Adapt?

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 level and will…

Higher education must immediately stop obsolete blackboard teaching.

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What is obsolete blackboard teaching?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.

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?
How learning can be more personalized with a decentralized syllabus that takes accoun…

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 ev…

Importance of educational videos and solving its limitation by teachers assistance

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 …

Beating confusion: The power of association

1) With increase in frequency, energy of electromagnetic waves increases or decreases

2) Molarity is
Often students confuse between molarity and molality.

3) In positive deviation from Raoult's Law, Solute-Solvent Interaction is strong or weak

Students often confuse with these kinds of answers, when there is a dichotomy.
It's nothing to do with the understanding of the subject, it's about memory. Students confuse because they have not formed enough association with main concepts. Eliminating these confusion requires memory tricks.

Let's work with the first two example:

The third one I leave to students or teachers to design so that they can memorize it.  In positive deviation, there will be more vapor pressure, this is only possible when solute-solvent interaction is weak. Weak intermolecular force means more particles in the gas phase.

Common prevailing myths in education that needs to be busted

A student is not scoring well, the main reason given:
He/She has the less innateability.
He/She was not working hard.

Let's bust the second myth first.
My question to schools, teachers, and parents is after spending about 6-7 hours in schools, or 24 hrs in residential schools and colleges, how can you really blame children for not working hard.
Why do schools expect children to study all by themselves? Why they have to do homework?
The problem is not about working hard, it's about not following effective study strategies. Not providing them to do enough retrieval practice. The implementing of the effective study strategies is a very complicated process and often contextual, so much of attributes involved, from content, curriculum to test questions. But the good thing is so much of research already available that will guide teachers to help students in learning.

Now the first myth:
She lacks the innate ability.
