Creating highly engaging online discussions to support sustainable formative learning Brant Knutzen Learning Designer Faculty of Education University of Hong Kong
Overview • Social Constructivism • Transactivity • Building engagement • Assessment methods • Participation rating • Measuring engagement
Computer-mediated Conferencing • CMC : Computer-mediated Conferencing • Synchronous : “chat”, or instant messaging • Asynchronous : “discussion forum” • Asynchronous • Participants take turns posting • Minutes, hours, or days apart • More time to digest, research, compose response
Social Constructivism • The effective construction of knowledge is a product of a functional collaborative group producing artifacts for public display and use • Efficacy has been found to be linked to the process that learners utilize in working on the task together (Fischer et al 2002) • Process: social negotiation of arguments and argument sequences (Leitão 2000; Voss & Dyke 2001)
Social Constructivism • John Biggs captured the educational value of discussion when he stated: "Good dialogue elicits those activities that shape, elaborate, and deepen understanding“ (Biggs 1999 p. 5)
Transactivity • Transactivity: the method by which students build on the contributions of their fellow learners (Berkowitz & Gibbs 1983)
Transactive online discussions • Transactive communication: • Participants respond to and build on each other’s contributions • Peer exchange of information and ideas • Social negotiation of knowledge • Each participant brings their own experiences to apply to a common educational goal
Transactivity • A key theoretical construct for measuring collaboration • How can we formulate the instructional design conditions which consistently result in more productive and transactive learning activities? • How can we describe it in easily grasped ways? • Quantitative • Qualitative
Online discussion – the potential • An online discussion is a great formative learning activity for building depth of student understanding, or supporting project work • Highest potential for social construction of knowledge and transactive collaboration • Unfortunately, this activity is also the most likely to FAIL! Why?
Study #1 – 2007 – Building Engagement • Case study of one course (Knutzen, 2007) • International school in Hong Kong – secondary level • 1-to-1 laptop blended learning environment • Introduction to Psychology course • Sample size = 24 • Investigation of instructional design conditions to achieve a highly productive online discussion • At start of study, average student production in optional online discussions = 1 post
Productive Communication • Four conditions to achieve productive online discussions: • Teacher facilitated social formation of small groups • Class time to initiate oral and online discussion interaction • Setting open-ended, challenging topic questions that encourage discussion and debate • Assessment system that reinforces production and peer interaction • At end of study, average studentproduction: over 10 posts per discussion!
Extensive use of discussion design • Over the past six years: • Extensive use of the online discussion design • Full-time instruction of secondary students • 1-to-1 laptop environment • IT classes • Psychology • Implemented at University of Hong Kong: 2009 • MSc IT in Education course on eLearning • Implemented in 12 courses at LingnanUniv : 2010 • Business, History, Social Studies, Philosophy, English • Design continues to result in good production
Designing discussion topic questions • One to three questions around one topic or area of content / concepts • Advantage of multiple questions: • Instructor can design a “gradient” of difficulty which can elicit a range of student answers • From basic knowledge -> higher-order thinking skills (HOTS) • Use a taxonomy of active verbs to specify the levels of understanding expected in answers (Blooms Revised, SOLO) • Examples: Multi-structural (list, describe, classify)Relational (compare/contrast, explain, analyze, relate)Extended Abstract (hypothesize, generate, reflect)
Designing discussion topic questions • Objective of multiple questions: • Make discussion accessible to all students • Challenge the advanced students • Other topic question gradients found to be useful: • Concrete facts -> abstract concepts • Textbook context -> personal context (unique answers!)
Designing discussion topic questions Example of a Topic Question gradient: Can you demonstrate what you have learned in your study of the Porter management models? • Can you list and describe the Porter models? (Basic understanding ). • How can you compare Porter's models? (Relational understanding)Can you relate these models to each other in several ways, or on several dimensions?. • Based on these models, can you create your own model? What factors do you theorize are important, and why? (Extended abstract understanding)
Discussion marking schemes • Traditional – teacher-assessed subjective marking • Review contributions by each student • Award mark based on: • Participation – any contribution to discussion • Interaction - responding and seeking feedback • Transaction – sharing / exchanging useful information and resources • Transformation – perspective change due to interaction with others • Best method for summative assessment • Should a discussion be a summative activity?
Using a Rubric for assessment • Criteria examples: • Locate, organize, analyze, evaluate, synthesize, and ethically use information from a variety of sources and media • Interact, collaborate, and publish with peers, experts, or others employing a variety of digital environments and media • Develop cultural understanding and global awareness by engaging with learners of other cultures • Contribute to project teams to produce original works or solve problems Source: ISTE NETS for Students
Problems with teacher assessment • A highly productive discussion can easily produce over 200 posts a week! • A teacher can become a victim of their own success • How much time can they devote to quantitative marking? • How much time remains for qualitativefeedback?
Peer-assessment • Desired graduate attributes: • Critical thinking skills • Excellent cooperative skills • Integrity • Personal responsibility • Subjective peer-assessment can directly address the development of these attributes • Requires student training • Requires review and evaluation by teacher
Peer-assessment - Subjective • Possible problems: • Revenge grading : 報復 • “you gave me a low grade, I will give you a low grade” • Back-scratching : 賄賂 • “If you give me a high grade, I will give you a high grade “
Sustainable forum assessment? • Teacher evaluation of forums: time intensive • Peer evaluation of forums: requires monitoring • Subjective evaluation of formative work tends to distort student learning • Optional forums do not get sufficient participation to create viable discussions
Leveraging the power of the LMS • Mysolution: automate the rating based on participation • No subjective judgment, just rating using a systematic method: • Moodle can automatically average these grades!
Rating based on Participation • Moodle averages the ratings • Grades produced by participation: • One post = 6 -> D- • Two posts = 8 -> B- • Three posts = 8.6 -> B • Four posts = 9 -> A- • Five posts = 9.2 -> A- • Six posts = 9.33 -> A • Seven posts = 9.42 -> A • Eight posts = 9.5 etc • More Q&A participation = higher grade
A foundation of participation • This assessment method for assessing a forum creates a foundation of participation: on average over 90% of students will engage • As always, the teacher’s role is to create the educational value of the activity: • Set up challenging topic questions to guide exploration • Maintain a “visible presence” in the forum activity • Successfully moderate the discussion

Participation-based forum grade • The Moodle LMS handles the awarding of quantitative marks for participation • Teacher can focus on quality: • Monitor progress • Guide the discussion • Challenge students • Time for thoughtful qualitativefeedback • Minimum: 30 mins to 1 hour each week per discussion
Motivating students to engage • Motivation on three levels: • Constructive alignment between formative discussions and summative final assignmentsExamples: • Reflective posts build towards a Learning Portfolio blog • Group collaboration on final project development • Social Constructivism: a sense of social obligation to support the group • Quantified Participation: each contribution is counted as participation towards a forum grade
The Participation Forum • Automates the awarding of participation points • Reduces technical requirements (modifying roles) • No need to train the students • No need to monitor rating accuracy • No need to motivate student ratings of posts • Finished development and testing in Dec 2011 • Currently in trials at HKU • Planned release as open-source project soon
Measures of discussion activity • Quantitative: • Production = Total number of discussion posts / n • Interactivity = Total number of feedback posts / n • Group Activity = Total number of discussion posts / # topics • Transactivity = Production × Interactivity • Qualitative: a new type of graphical representation – the “Participation Map” • Developed at Lingnan University in 2011 • Continued development as open source project
The Participation Map • New Moodle plug-in automates the production of the map of discussion activity: • Quantitative statistics • Qualitative graphic display: a “data portrait” • Useful for displaying discussion activity • Feedback to students in the class (who is working?) • Feedback to teacher (what approach is working?) • Anonymous mode for reporting research results
Example Participation Map Overall discussion statistics Red line shows rating cutoff Time scale from Day 1 to Day 14 Students can interact in multiple groups Student profile pictures Group comparison stats
Quantitative Data • Quantitative ratings of overall discussion
Participation Map is a teacher tool • After install on Moodle server, this plugin is only available to those with Teacher roles • New option on CourseAdministration block
Participation Map operation • Select theforum, andthen plot type: • Normal plotfor feedbackto teacher andstudents • Anonymousfor reportingresults outside
Questions and Discussion • Currently setting up a website to make these open source projects available to the Moodle educational community: Brant.Knutzen.se • Goal is to release both as free open source plugins for Moodle 2 by Sep 2012 • Q & A ?? • My email is brantknutzen@gmail.com
