  3. 3. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Motivation We need to explore new information technologies to face the new challenges of the European High Education Area. → Current technologies do not meet the requirements: forums, chat, web pages, word documents, ... Requirements Flexibility Asynchronous work Easy to access and use Student activity tracking Portability → A wiki meets all of these requirements!! GIIDES - Wiki Wikis at UAB 3 / 35
  4. 4. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. What is a wiki? Wiki definition A Wiki is a web space where different authors can collaborate in the dynamic creation of documents. No expertise on IT required for using it. Mechanisms for cooperative work. Tracking: recent changes, subscriptions, ... Allows attaching external documents. Easy using / low cost for maintenance. GIIDES - Wiki Wikis at UAB 4 / 35
  5. 5. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Wiki for learning The wiki has been used in many scenarios: Research groups (writing papers, meeting minutes, state of the art), teams in companies (project oriented work), global projects (Wikipedia), ... It can also be used to improve learning, for it provides: A peer-to-peer communication channel A collaborative editing system with version control An automatic repository Free organisation of information It can be considered an enhanced virtual portfolio, but allowing continuous team work, and promoting active participation.

  6. 6. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Interest group Mission Design Example The wiki experience at UAB The “Wiki” Interest Group on Higher Education Innovation at UAB has been using this tool since 2004. Some facts: We have carried out more than 80 experiences, in more than 10 majors. We are 11 instructors from 6 different departments at UAB. There has been an important improvement of academic results of students (more motivation, less absence, better marks, more students write the exam). GIIDES - Wiki Wikis at UAB 6 / 35
  7. 7. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Interest group Mission Design Example Mission Our objectives are to Extend the workgroup model used for laboratories Improve the learning process of students. Increase the motivation of the student. Make students participate actively, even those who have a job and cannot attend to classes. GIIDES - Wiki Wikis at UAB 7 / 35
  8. 8. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Interest group Mission Design Example Designing a wiki Although there are many advantages in using a wiki for supporting learning, there are some key aspects that must be firstly considered: Important aspects: Information organisation / Wiki structure. Designing of the learning evidences. Time devoted for following up student progress. Assessment of the contributions to the wiki. All these aspects must be perfectly defined before using a Wiki. GIIDES - Wiki Wikis at UAB 8 / 35
  9. 9. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Interest group Mission Design Example Reported wiki learning hindrances There is a list of well-known learning hindrances when using a wiki (http://www.educause.edu). → This is how we have overcome them: Group editing (All documents are edited by a group of students, no private information). An access and change control is used. Content structure (Free structure makes assessment difficult). Learning evidences define the structure of the wiki. Collective group representation (The group is assessed as a whole). An individual assessment is performed. GIIDES - Wiki Wikis at UAB 9 / 35
  10. 10. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Interest group Mission Design Example Access and change control A specific implementation is used for access and change control.

  12. 12. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Interest group Mission Design Example Individual assessment The assessment process is individual. For every learning evidence this is taken into account: Quantitative and qualitative elements Constancy Reactivity Concept integration Command of terminology Group participation GIIDES - Wiki Wikis at UAB 12 / 35
  13. 13. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Interest group Mission Design Example Facing the problem of large classes The ratio instructor/student in Computer Engineering is very low (1/150, 1/200, ...). Peer-to-peer assessment has proved to be an important tool to facilitate instructor’s task. Peer-to-peer assessment One week period every month. Every wiki group assesses the wiki of other two groups (assessment and answer). Concise form. Special scripts for MoinMoin GIIDES - Wiki Wikis at UAB 13 / 35
  14. 14. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Interest group Mission Design Example An example This is an example of a wiki used for the subject “Computer Networks II” (in the 4th year of the 5-year Computer Engineering, +200 students). Wiki teams of 6 students. Learning evidences Exercises (10): Three stages: Writing, Remarking, Correcting Extensions (2), in groups of 3. Field work (1), in groups of 3.

  24. 24. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Evaluation According to the surveys at the end of every experience: + The wiki facilitates the groupwork and increases the active involvement of students. + Improves academic performance. – Work volume in significantly increased for both students and instructors (consequence of continuous assessment?). – Reluctances to peer-to-peer assessment. GIIDES - Wiki Wikis at UAB 24 / 35
  25. 25. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Results Some basic figures about the results: Final exam and overall marks have increased. Number of students not taking the exam slightly increases. Significant increase of students who, having taken the exam, pass the subject. GIIDES - Wiki Wikis at UAB 25 / 35
  26. 26. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Weaknesses of the wiki The wiki is very powerful, but in these four years of applying it we have found some weaknesses: It is difficult to control the time needed by student and instructor, and the time they have devoted to the wiki. There are many variables to assess; an external spreadsheet is required to keep all the evaluation notes. Setting up teams can be tedious: a typical course in Computer Engineering may have more than 200 students. GIIDES - Wiki Wikis at UAB 26 / 35
  27. 27. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools manager Activity tracker Assessment Time C Tools Wiki Conc. New wiki tools Our group has devised new wiki tools to assist students and instructors to overcome these weaknesses, and to create a wiki which is specific for teaching. New wiki tools developed: Wiki manager Student activity tracking Time Control Assessment notes GIIDES - Wiki Wikis at UAB 27 / 35
  28. 28. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools manager Activity tracker Assessment Time C Tools Wiki Conc. Wiki manager The new wiki manager assists the instructor in the task of creating and managing wikis. Now it is trivial to create a number of wikis for teams in the same course, only with one click. GIIDES - Wiki Wikis at UAB 28 / 35
  29. 29. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools manager Activity tracker Assessment Time C Tools Wiki Conc. Student Activity Tracking It is convenient to analyse the activity of a student in the wiki. With this new tool all this information, not accessible in a traditional wiki, is available instantaneously. GIIDES - Wiki Wikis at UAB 29 / 35
  30. 30. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools manager Activity tracker Assessment Time C Tools Wiki Conc. Assessment To avoid the need for having an external document to keep track of the assessment of the student, we have created the assessment note. An assessment note, public or private, can be attached to every page in the wiki. GIIDES - Wiki Wikis at UAB 30 / 35
  31. 31. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools manager Activity tracker Assessment Time C Tools Wiki Conc. This is how one of these assessment notes looks like: GIIDES - Wiki Wikis at UAB 31 / 35
  32. 32. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools manager Activity tracker Assessment Time C Tools Wiki Conc. Time Control In order to make a better control of time, every student may indicate how much time he or she has spent in doing the activity. GIIDES - Wiki Wikis at UAB 32 / 35
  33. 33. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Conclusions A wiki is extremely useful for supporting learning, and the UAB Wiki group has been using it since 2004. However, a generic wiki lacks from some basic functionalities such as Time control tools Detailed user activity information On-line assessment Easy creation of team wikis Our group has developed an extension for the MoinMoin wiki engine to support these functions. GIIDES - Wiki Wikis at UAB 33 / 35
  34. 34. Aim Wiki Learning UAB Evaluation and results Weaknesses Tools Conc. Future work We are planning now to integrate a wiki in the institutional electronic teaching platform at UAB (expected by 09/2008). This wiki will have, eventually, all the tools we have devised. We will focus on competence assessment via wiki, as this is of paramount relevance now for the new majors that are currently being defined. We want to create a network of groups interested in wiki for learning (groups from 5 universities interested so far). GIIDES - Wiki Wikis at UAB 34 / 35
