This is my first time for this subject, Effective Presentation in English. I started with my basic on English that was not enough for better work for this session. The lessons were started by how to introduce yourself and the topic for presentation. I had studied about many ways to welcome the audience and introduce myself politely and formal. And also had checklist instructors for introduction. For this session I had studied many new ways to talk for lead the audience to follow my presentation but I think it would like to have more examples. And also had a group work for practice the lesson. The first story of our group presentation is Chicken pox. I knew that I had few problems to make the presentation smoothly such as forgot some points from the checklist and have a lot of diffidence and exciting but for the first time I think we had done the best for our work. By comparing with the other groups which also had the first time for this subject, some groups had shown their diffidence eminently but from some group I could bring their confidence and skill to improve our method to introduction. For this session I can bring whole strategies to apply with other subjects presentations for introducing my topic in the future such as the senior project. I think this is the useful lesson that effected the audience first impressions and lead them to our topic easily. We finished our class with homework in course book chapter one and two.
