Just as the absence of brainstorming can lead to ineffective writing, the absence of preparation before speaking can result in ineffective and inefficient speech delivering. As a result, Aii Language Center has conducted a workshop for level 7b students who will be having their slide presentation in the near future. The workshop covers significant elements such as how to design a proper slide PowerPoint, how to dress professionally and how to portray oneself confidently. Without doubt, this workshop is a helpful guide that students can always refer to whenever they have to do a presentation not only in academic fields but also professional fields.
