The first video for chapter 10 goes over using language to engage your audience. This can be done by putting language in context as in relating to what is currently going on whether that is referring to your audience or an event that happened on campus. Using personal language is the next one by using words like we, us, you, and I. Use inclusive language which means not using words people may not understand or may offend them. Use visual language which includes similes, metaphors, parallelism, rhymes, alliteration, and antithesis. It also goes over sparking imagination with language by asking the audience to visualize a story or idea.The second video for section 10.2 Talks about using effective language by using meaningful words, balance between clarity and ambiguity, be concise, avoid offensive language, build repetition, and don't get attached to your words.The first video for chapter 12 goes over delivery. Paying attention to volume, pitch, rate, avoid pauses, do not use monotone voice, and use good articulation and pronunciation. The next video goes over good delivery with eye contact, facial expressions, effective body movement, gestures, and appearance. The third video for chapter 12 goes over practicing your speech. You can do this by using your presentation outline and your note cards. They say you can practice your speech in sections. Practice in front of small audience and your confidence will be boosted. I though the most helpful part was that it talked about delivery and engaging my audience through language because I personally overlook that.
