Robinson, James, Turner, Jeanine, & Watters, Kathleen

measurement issues prca
Measurement Issues: PRCA
  • The identification of appropriate measures for the assessment.
    • PRCA – Personal Report of Communication Apprehension
        • 6 item measure of public speaking anxiety
    • PRCA used in 1,000 published studies.
    • Reliabilities reported in the .80 range
prca items
PRCA Items
  • “My thoughts become confused when I give a speech.”
  • “I face the prospect of giving a speech with confidence.”
  • “Certain parts of my body feel tense or rigid while giving a speech.”
  • “I get so nervous I forget facts I know.”
measurement issues spcc
Measurement Issues: SPCC
  • SPCC – The self perceived communicative competence measure.
      • 3 item measure of public speaking competence
  • SPCC widely used in research & assessment of public speaking courses.
  • Reliabilities reported in the .75 range
spcc items
SPCC Items
  • On a scale of 0% to 100% how competent are you at the following:
    • “Present a talk to a group of strangers.”
    • “Present a talk with a group of acquaintances.”
    • “Present a talk to a group of friends.”
pilot study
Pilot Study
  • Measures were tested in class (n = 109 Ss).
  • Internal consistency PRCA = .86* for public speaking items.
  • Internal consistency for SPCC = .79* for public speaking items.

*Cronbach’s alpha

assessment website
Assessment Website
  • An assessment website was constructed.
  • An introduction & explanation on the assessment process was included.
  • The measures were then turned into forms using Microsoft FrontPage
the assessment website
The Assessment Website
  • Reduces time spent generating & distributing assessment materials.
  • Reduces the money spent reproducing the materials
  • Reduces the time spent analyzing assessment data.
    • No scanning & importing ASCII files.
    • No reproducing variable labels.
additional technology
Additional Technology
  • Ss typically make two speeches in this course.
  • Both are made in class – utilizing 45% of all class time.
  • Ss typically give a variation of the same speech.
additional technology1
Additional Technology
  • To alleviate this problem, Ss are required to tape their speech outside of class and bring it to the instructor
  • Ss may practice and record the speech as many times as they like.
  • This forces Ss to practice the speech before they present it in class.
additional technology2
Additional Technology
  • Ss receive more instruction & less time listening to speeches that are not well prepared or are redundant.
  • Instructors can pour over the speech and look back and rewind speech.
  • Instructors can point out specific problems and shoe the Ss.
  • Putting Ss in charge of solving the technology problem, empowers Ss.
  • Taped speeches reduce Ss complaints about differences in perceptions of the speech.
    • Vocal segregates, eye contact, note of finality, transitions.
  • Instructors perceive speeches to be much improved.
  • Ss report feeling more clear about what the instructor “wants.”
  • Ss watch their speech and realize there are many things they could do to enhance their performance.
future projects
Future Projects
  • Stream the speech on assessment website instead of using transcript.
  • Provide Ss with firewire webcams for public speaking courses.
  • Submit the speeches to their instructors as video attachments on the new media server system.
future projects1
Future Projects
  • Create a video speech library for Ss.
  • Identify the most common Ss errors to improve future speech education.
  • Provide instructors software to embed comments in a second audio track.

  • Fractionate speech into components.
    • Attention
    • Purpose
    • Preview
    • Main Points
      • Evidence

    • Conclusion
    • Closing summary
    • Note of finality
    • Efforts at credibility
    • Message adaptation
  • Ss provide each component online to instructor.
