  1. INFORMATIVE SPEAKING

  2. Informative Speaking What is information? “That which reduces uncertainty.” (DeVito, 2002) “Information speaking is discourse that imparts new information, secures understanding, or reinforces accumulated information.” (Berko, et al.,2004)

  4. TYPES OF INFORMATIVE SPEECHES • Explanations – answer How? • Descriptions – person/place/thing • Definitions – what is? • Narratives – tell a story

  7. Methods of Defining • Comparison/Contrast • Synonym example • Antonym • Etymology • Conceptually • Operationally

  8. Definitions: Conceptual Vs. Operational Conceptual: Lies in the verbal (abstract) universe.

  9. A good conceptual definition possesses: • Parsimony: conciseness; uses as few, but specific, words as possible • Clarity: divides the word into two halves • Scientifically heuristic: explains; defines; and predicts phenomena; promotes further investigation

  10. Operational Definition Describes what is to be observed by specifying HOW to observe. A method of observation must satisfy two criteria: reliability and validity

  11. Reliability: the consistency of a measure with itself • Validity: the degree to which a measure actually measures what is claimed • Face validity: it looks good; common sense says it is a good measure • Expert validity; a group of “experts” have judged its merit • Criterion validity: compares the measure with (1) previous measures, or (2) allows prediction between known groups • Construct validity: New measure is administered alongside two other measures, at least one of which already had proven validity.
