There are three things which you should have to do well in lecturette .
1. Knowledge
2. Confidence
3. Presentation
Knowledge
It can be developed by using newspapers. But the main problem is that, we don't know the proper way of reading newspaper.
• If your English is slightly weak ,don't start directly reading the Hindu newspaper . Start with Indian Express or Deccan chronicle .
• The main heart of newspaper is the article section. But just don't read it ,try to analyse and create your own opinions .
• Watch videos of the Hindu newspaper analysis by study iq on you tube .
Confidence
Once you have knowledge ,the second thing which comes is confidence . Now how to improve it ?
• Take out the shyness of speaking english . Try to talk with your family members in English.they may not understand but try to speak with them and teach them too.
• Practice in front of a mirror . And speak by looking directly into your eyes . Because eye contact is very important.
• Some people have habit of shaking their legs while standing or sitting .Try to avoid it .
• Keep your hands locked behind . ( Vishram position )
Presentation
Now it may so happen that you have prepared important topics from some books , website or coaching institute . So you may have lots of knowledge about certain topic with you.but time limit given is only 3 minutes.and you need to be precise in your speech but how ?
• For example take Jammu and Kashmir topic if you start it . You will take hours to complete it.
• So you should first give a basic idea of where Jammu and Kashmir is located ,it's importance to India,Why so much violence is present there and what measures can be taken to bring peace in that region.
• Now some people start with the history of Jammu and Kashmir and remain in the history of J &K, and the 3 minutes completes . So even though you have vast knowledge you are not able to plan your speech.
• Some people just speak something without factual information in it . Try to use factual data while speaking . And avoid beating around the bush.
• For example if the topic is J&K . Don't start speaking about article 370.
