WEEK 3 - Basics of logic and process of learning

 Let's see what statement logic is

• Logically analysing statements of a compound statement( a statement with 2 or more than 2 propositions)  is quite similar to solving logic gates.(If you have a basic understanding of logical operations in computer science)
• In statement logic we analyse a compound statement,that is to check it's truth value by looking for relationships between statements/prepositions as pairs.
• There are five basic categories under analysis of statements as given in the table below.
  

Conjunction: All propositions must be true for the compound proposition to be true.

A : Tom is an actress    B: Tom is rich

A  AND B : Tom is an actress and he is rich

Disjunction : At least one statement need to be true at a given time for the compound statement to                         be true.

C: John will go the market in the morning.         D: John ,will go to work in the morning

 

C OR D : John will go to the market or go to work in the morning.

Implications:  Second premise is resulted from the first. Both premises are related.

Biconditional: Second premise can result in the first or it can happen in either way. Both                                         statements are either true or either false.

Negation :A statement opposes it’s original statement. Both of them cannot be true at the same                         time.

P1- Shia is thin                            P2-Shia is not thin. 

This sentence can be expressed as P1= NOT P2.

How far do you know about learning?

Can you recall everything you learned from your very early childhood? Probably not. You remember what you keep in touch, things you practice often. This proves that memory is not permanent.

      Learning is a complicated process acquired through experience and results in relatively permanent changes  in brain structure. Thus learning involves in forming in new neuro connections when you learn something new. But in order to to form long term memories these neuron networks are needed to be activated through practise.

    As college students, it is important for us to manage time for learning effectively in order to get other activities done at the same time. Effective learning has become a challenge according to my experience due to teacher centered approach of learning. The pandemic we are facing today is also partly responsible for the situation we are facing today. But teacher centered approach may not be entirely bad. This approach encourages cooperation between teacher and student. Structure of syllabus is well introduced excluding irrelevant materials. Also, there can be areas of study that a student is not confident about and can be directed to the teacher as younger children believe what teacher says, even more than their parents. In teacher’s side, with set syllabus it would be easier for him to achieve targets through students. I believe this system is ideal for younger kids. But still knowledge from this approach is limited. Thus, student centered approach is becoming dominant.  Not restricting students to a study aiming an exam put them under less pressure. They get the chance to share knowledge and experiences and discover knowledge out of boundaries.

Here are a few tips to make learning effective.

• As the saying goes, "If you don't work to a plan, you are planning to fail" it is an important step to plan your day. This will help you keep work organised.
• Give your brain a downtime between different learning activities. This will boost your mood and enhance creativity.
• Use several methods during learning. ( Teaching others, using reference materials, discussions)
• Make sure you are having a good diet and enough rest( An average adult requires 7 to 9 hours sleep)
