So, we given a task to review our friends' blog/videos.
It is for us to develop our critical thinking in order for us to be able to give comments to our friends.
It can be done in a very quick way actually. On top of that, by giving us opportunity to comment on each other works, we will indeed try to improve ourselves in critical thinking and communication skill as well.
Indeed, this activity can trigger students' interest and motivation in giving personal opinions about something which is rather good for university's students to fully use their mind to think of something. Opinions have no right or wrong, and it depends on the person who received those comments, whether they want to take it and make a change or vice versa.
Thank you for reading this, God Bless You !!!
