Seminar

This course will enable the students to have following skills:

CO 73: In terms of content, students will be able to show competence in identifying relevant information, defining and explaining topics under discussion.In terms of organization, students will be able to show competence in working with a methodology, structuring their oral work, and synthesizing information. In terms of delivery, students will use appropriate registers and vocabulary, and will demonstrate command of voice modulation, voice projection, and pacing. They will be able to make use of visual, audio and audio-visual material to support their presentation, and will be able to speak cogently with or without notes. 

CO 74: Students will be able to judge when to speak and how much to say, speak clearly and audibly in a manner appropriate to the subject, ask appropriate questions, use evidence to support claims, respond to a range of questions

CO 75: Students will demonstrate that they have paid close attention to what others say and can respond constructively. Through listening attentively, they will be able to build on discussion fruitfully, supporting and connecting with other discussants. 

CO 76: Through asking appropriate questions, students will demonstrate their understanding of discussions and spark further discussion.
