When planning an oral presentation, you want to make sure to do all of the following except _____.1. Type up a paper to read to your audience
2. Practice presenting in front of friend or family
3. Practice presenting in front of a mirror
4. time the length of your presentation

Answers

Answer;

3. Practice presenting in front of a mirror

Explanation;

Like scientific papers, oral presentations at a conference or internal seminar are for sharing your research work with other scientists. They, too, must convince the audience that the research presented is important, valid, and relevant to them.

Planning a presentation involves a comprehensive assessment of the speaking situation. It is important to know the purpose of the presentation, know the audience and also where the presentation will take place, among other important aspects.

Answer:

The correct answer is option 2. Practice presenting in front of friend or family

Explanation:

Generally while making an oral presentation three things are very vital-

a) Cover all the vital points of the research work presented through oral presentation thus writing all the points on a piece of paper is must.

b) One must use appropriate body gesture while giving the presentation , thus practicing in front of mirror is also a required exercise

c) The presenter must be able to deliver his/her presentation in the stipulated time period thus timing the presentation is also important.

Since mirror practice is sufficient to work on body language, eye contact with the audience and gesture, thus there is no need to practice in-front of friend or family.
