CBSE and other boards, All about rote memorization of abstract information

By

Most questions of CBSE 12th board, all requires rote memorization of abstract information that adds no understanding to the subject.

 Let us analyze the style of question in CBSE:

This is the question from book Nivaldo J Tro:

The question gives some background knowledge,  structures are already given and the question really tests your understanding, not how much you have memorized.




Answer:  Option Vitamin C and Vitamin B5 are water soluble as it contains many polar groups and others have large nonpolar groups (Vit K3 and Vit A) so its fat soluble.



What type of questions you will expect in CBSE?
Name the water soluble vitamins and fat soluble vitamins?
or Something like is Vitamin C water soluble? (The structure of Vitamin C will not be given)
How are vitamins classified? Name the vitamin which is fat soluble.

"All these questions require rote memorization of vitamins:"

Fat soluble vitamins are A D E and K
Water soluble vitamins are Vitamin B

So, just rote memorization is enough, you needn't have to understand why A, D, E and K are fat-soluble. Even if you understood it, still you have to do lot of rote memorization (may be using mnemonics)

Let's compare some more questions:

Questions on polymer:


So in the question itself, monomers structures are already given. You have to use your understanding to get the polymer out of it.

In CBSE questions will be like this:

Write the names and structures of the monomers of the following polymers:
i) Polystyrene ii) Dacron iii) Teflon

 Arrange the following polymers in the increasing order of their intermolecular forces (the structure are not given, so you have to memorize all those abstract structures to get the answers)
Polystyrene, Terylene, Buna-s

Our book contains about 30 complicated structures and complicated names of polymers and its monomers, which you have to rote memorize.



In science, using only a few fundamental concepts, all other concepts are built upon it.

Take the example of organic chemistry, it's all about book-keeping of electrons and mechanisms (e.g. ARIO: Atom, Resonance, Induction, Orbital).

In organic chemistry or any subject, questions must be descriptive with diagrams (pairing graphics with words study strategy) that make you curious to solve, even if you don't know the answer.

Look at this question:
Compare the following compounds, which compound is more acidic?


It tests the understanding of the induction effect. Even if you don't know about induction effect, you will try to think about it and predict something, if you know Cl is more electronegative.

But our board will only ask rote memorization abstract questions just as
ISC question in Organic Chemistry





"All books must be removed from recommendation if it doesn't meet the learning criteria from next session. This is the most important thing we need to do to save our children and all future generations."

The overview of fair democracy: https://iambrainstorming.wordpress.com/from-hypocrisy-to-democracy-this-way-delegated-proof-of-stake-2/   Evolutionary democracy using hierarchical specialization with adapted delegated proof of stake algorithm, where different specialized departments are in a symbiotic or mutually beneficial relationship.  The Tree of Democracy Each funnel is a department with its subdepartments A Department For example, the education department can have its sub-departments such as kid education, adult education, research, entrepreneurship. Each department consists of large outer representatives and a few inner representatives. These large outer representatives are the grand total of all its sub-department outer representatives and the few inner representatives are the grand totals of all its sub-department inner representatives. Inner representatives of center and state are policy approver,   and inner representatives of all the regions (center, state, ...

A new fair democracy inspired by Delegated Proof of Stake algorithm

Preprint link: https://osf.io/82mpk/ dem·oc·racy [democracy democracies] 1) fair and equal treatment of everyone in a country or organization, etc, and their right to take part in making decisions 2) a system of government in which all the people of a country can vote to elect their representatives Yes, most democratic countries fulfill the second definition of democracy, but none to the first definition. Abstract: Democracy is about fair and equal treatment of everyone in a country. But it becomes unrealistic to achieve when political parties have their conflict of interest , and leaders don't have the expertise to make evidence-based policies and neither have the skill and manpower for solving problems that surround our society and ecosystem. The new fair democracy provides an elegant way of governance that separates the representative responsibility according to their specialization and can grow into any complexity. The governance is divided into various departments, and each ...

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...
