What is formative e-assessment?
            Formative?
          ‘practice’ assessment /
          serial summative assessment                                    synonymous with learning

The e?
The use of digital
means to support

                Alternative view:
                Formative features of assessment,
                which are afforded by specific
                features of digital media                                                               4

OK, so what do we mean by
     Formative Assessment?
“An assessment functions formatively when
  evidence about student achievement elicited by
  the assessment is interpreted and used to make
  decisions about the next steps in instruction that
  are likely to be better, or better founded, than the
  decisions that would have been made in the
  absence of that evidence”
(Dylan Wiliam)
                                                                                                    5
      Yishay Mor / formative e-assessment / http://talks.yishaymor.org/e-assessmentinpractice2009
Formative = feedback + moments of
           contingency
"... These create "moments of contingency," in
  which the direction of the instruction will
  depend on student responses. Teachers
  provide feedback that engages students, make
  time in class for students to work on
  improvement, and activate students as
  instructional resources for one another."
(Leahy, Lyon, Thompson, and Wiliam 2005)
                                                                                                     6

Participatory Methodology for

  – Acceleration → need for effective protocols for sharing
    of design knowledge

• Context
  – interdisciplinary communities of practitioners
    engaged in collaborative reflection on a common
    theme of their practice.

Problem: The Design
Divide

the gap between those who
have the expertise to develop
high-quality tools and
resources and those who
don’t (Mor & Winters, 2008*)



the critical resource is not the capacity to
produce, but the knowledge to do it right.

Situation
   large class (138), first and second year computer science students.
      assignment: create a virtual pet in Second Life.

Task
   −   Engage and motivate the students
   −   show examples of good work which others could
       learn from
   −   show students their work is valued.
   −   build a sense of community.

Situation
  −   Grammar school been piloting the ‘string comparison’ approach to
      language teaching at post-16 for AS and A2 level students.
  −   Sixth Form level, grammatical consolidation and whole-sentence
      translation.

Task
  −   Allow students to practise written language
      independently and receive feedback on errors in
      order to improve their language skills.

          Yishay Mor / formative e-assessment / http://talks.yishaymor.org/e-assessmentinpractice2009
Solution
A bespoke string (sequence) comparator was
 designed; uses fine-granularity sequence
 comparison to compare correct language
 strings to a user’s answer. Students answer
 questions and the comparator marks up errors
 in their input using colour coding (and font
 style) to highlight the different types of error. If
 an answer contains errors the student is given
 a second attempt in which to correct the
 submission based on the feedback received.

Problem
Lack of immediate feedback for students
leads to fossilisation of errors and
misconceptions




                                     providing immediate feedback in an
                                     iterative fashion can also hinder
                                     effective learning since students are
                                     able to "grope their way" step-by-step
                                     to a correct solution without
                                     necessarily having to think about each

         Yishay Mor / formative e-assessment / http://talks.yishaymor.org/e-assessmentinpractice2009
Solution
Embed a mechanism in the learning and teaching system
 that regularly captures tutor feedback, analyses it, and
 presents them with graphical representation of the types of
 feedback they have given. Ideally, this should also include
 constructive advice as to how to shift from less to more
 effective forms.
In computer supported environments (e.g. VLEs), this
   mechanism could be integrated into the system, providing
   tutors with immediate analysis of their feedback, as well as
   long-term aggregates.

Example scenario
When using Try Once Refine Once there is a risk
                             Once,
 that high-achievers do not receive feedback.
So -
Use Showcase Learning to celebrate students’
 work and provoke feedback from peers and
 tutors.
Use Feedback on Feedback to alert tutors to the
 problem.

                                                                                                      42

Conclusions
Tip of the iceberg
Practitioners (educational / software)
  acknowledge the value of patterns, when served
  with side dishes of cases + scenarios
Collaborative elicitation of patterns from cases
 could be a potent form of professional
 development.

    OK, so whatdo we mean by Formative Assessment? “An assessment functions formatively when evidence about student achievement elicited by the assessment is interpreted and used to make decisions about the next steps in instruction that are likely to be better, or better founded, than the decisions that would have been made in the absence of that evidence” (Dylan Wiliam) 5 Yishay Mor / formative e-assessment / http://talks.yishaymor.org/e-assessmentinpractice2009

    Formative = feedback+ moments of contingency "... These create "moments of contingency," in which the direction of the instruction will depend on student responses. Teachers provide feedback that engages students, make time in class for students to work on improvement, and activate students as instructional resources for one another." (Leahy, Lyon, Thompson, and Wiliam 2005) 6 Yishay Mor / formative e-assessment / http://talks.yishaymor.org/e-assessmentinpractice2009

    Post 16 stringcomparison (Aliy Fowler) Situation − Grammar school been piloting the ‘string comparison’ approach to language teaching at post-16 for AS and A2 level students. − Sixth Form level, grammatical consolidation and whole-sentence translation. Task − Allow students to practise written language independently and receive feedback on errors in order to improve their language skills. http://purl.org/planet/Cases/Post16stringcomparison 25 Yishay Mor / formative e-assessment / http://talks.yishaymor.org/e-assessmentinpractice2009

    Solution A bespoke string(sequence) comparator was designed; uses fine-granularity sequence comparison to compare correct language strings to a user’s answer. Students answer questions and the comparator marks up errors in their input using colour coding (and font style) to highlight the different types of error. If an answer contains errors the student is given a second attempt in which to correct the submission based on the feedback received. 26 Yishay Mor / formative e-assessment / http://talks.yishaymor.org/e-assessmentinpractice2009

    Problem Lack of immediatefeedback for students leads to fossilisation of errors and misconceptions providing immediate feedback in an iterative fashion can also hinder effective learning since students are able to "grope their way" step-by-step to a correct solution without necessarily having to think about each answer as a whole. 30 Yishay Mor / formative e-assessment / http://talks.yishaymor.org/e-assessmentinpractice2009

    Feedback on Feedback (Linda McGuigan) 33 http://purl.org/planet/Patterns/FeedbackonFeedback
  • 34.
    Good feedback should- Problem Alert learners to their weaknesses. Diagnose the causes and dynamics of these. Include operational suggestions to improve the learning experience. Address socio-emotive factors. Tutors know this, but are pressed for time. Or not aware of their feedback strategies Large teaching organisations are not equipped to provide tutors with personal feedback on their teaching 34
  • 35.
    Context Large scale, technologysupported, graded courses − many tutors instructing many students. Feedback is mediated by technology that allows it to be captured and processed in real time Topic of study is subject to both grading and formative feedback. 35 Yishay Mor / formative e-assessment / http://talks.yishaymor.org/e-assessmentinpractice2009
  • 36.
    Solution Embed a mechanismin the learning and teaching system that regularly captures tutor feedback, analyses it, and presents them with graphical representation of the types of feedback they have given. Ideally, this should also include constructive advice as to how to shift from less to more effective forms. In computer supported environments (e.g. VLEs), this mechanism could be integrated into the system, providing tutors with immediate analysis of their feedback, as well as long-term aggregates. 36 Yishay Mor / formative e-assessment / http://talks.yishaymor.org/e-assessmentinpractice2009
