Discuss with group using Whatsapp

Hello, meet again, on my blog. On this blog I want to discuss the advantages and disadvantages of discussion using an online application, namely Whatsapp. Previously I would like to explain the tasks we did via Whatsapp. In ICT lessons, we were assigned to make a paragraph about "What we learned during these two semesters". After that, we are assigned to give feedback, every paragraph of mine. The following paragraph I wrote:

"I feel happy because I can learn many things that I don't know. In addition, I also received additional knowledge because, in this ICT lesson, I was taught how to present good and true. Besides that my obstacle in this lesson is that I haven't used the technology too well, so there are two things that are still wrong. The rest I am very grateful to my supervisor in this ICT lesson, Ms. J, because it provides a lot of knowledge that I have never been able to in previous ICT lessons. All of me, God bless you. Thank you". And here are feedback from my group friends, along with feedback;

Furthermore, after the feedback that was given I was able to improve my paragraph. After discussion and discussion via WhatsApp, I think I feel that discussing at Edmodo has advantages and disadvantages. The advantages of discussion via Whatsapp, the excess: Discussions in via WhatsApp can make it easier for us to learn. We can have discussions anywhere.

But the disadvantage is that if we want to build a discussion, we need the internet, besides that we also can't know the punctuation and expression of each chat. Thank you, thats all for me .
