Motivation – why
 bother?

Implementation – what
  was done and how?

Suggestions for local
  implementation

Motivation – why bother?

Richer student-generated feedback on presentations

Student engagement with presentations other than their
  own

Need to be time efficient

Little previous use of this application of EVS

Implementation – class details

Hons (year 3) Media and Eng Lit class

No previous use of EVS handsets

3 sessions with seminar groups of 15-20 students

Student assessment of their peers was not summative



                                                      4

Implementation – assessment details

Instructor assessed summatively – content, delivery,
   timing visuals

Student assessment questions criteria determined
  through discussion with previous year’s class

Based on tutor Qs but adapted for student perspective

Most Qs scored on numerical scale of 1-10

Implementation – marks

Student marks comparable
But all very high with not much
differentiation

Ranges : 71-90 (students) 72-89 (tutor)
Means identical to nearest %

Interesting case is student 6 – misinterpreted question but lively
   presentation (low tutor score, high peer score)



                                                                     7

Implementation – student feedback

Anonymity of handsets appreciated

Engagement - more attentive to session

Assessment over several sessions – ‘fixing’

Serial Q responses – slow

10Qs per student – ‘button fatigue’

Unanimous that it should not be summative

Evaluation – my thoughts

An interesting study in an appropriate area

Achieved some of its aims



    Were I to do it, I would do things slightly differently




                                                              9

1. Can’t assume students are confident
  assessors, partly because they rarely
  assess

Need to run a dummy exercise as a training
 session

Illustrate with short examples of ‘staged’ good,
   average and poor presentations



                                                   10

2. Students should feel some ownership of
  the peer assessment component

Develop assessment criteria and questions with
 whole class discussion input (this year’s class!)

Trial with training exercise presentations

Discuss and if necessary refine


                                                     11

3. Simplify the questions / choices

10 point scale is far too fine

Suggest replacing it with statements rated on a
  5 point Likert scale (or 6 point Osgood)

Reduce the number of questions to the
 minimum needed to cover all the assessment
 issues

4. Consider letting students assess different
  things to tutor

If similar criteria assessing same components of
   presentation, won’t you always expect similar
   scores?

Why not let students assess suitability of e.g.
 content, subject to development of criteria
 through training?

Consequences

+ Students as partners in the development of
  PA criteria
+ Normalisation of expectations ahead of real
  session: ‘on the same page’
+ Encourages reflection before students create
  and deliver their own presentations

- Takes 1-2 hrs additional class time
  (but probably time well spent)

                The University of Edinburgh



Finally…..

I think you could allocate a proportion of the
   summative assessment to this process, if
   criteria transparent and students trained as
   suggested.
