A constructivistic instructional model that organises learning around projects. Project-Based Learning Advantages Ø Ø Ø Increases student motivation Improves student problemsolving Promotes meta-cognition Promotes self-regulated selflearning Opportunities for interdisciplinary learning Culminates in realistic results Challenges Ø Ø Ø Ø Ø Initiating inquiry Direct investigations Managing time Overcome writer’s block Limited experience in project design Collaboration & feedback Project follow-up Monitoring progress Monitoring knowledge Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001

EVA_pm ML Markup Language for project specification & management Ø specification (setting goals, breaking them up into achievable objectives) scaffolding to initiate inquiry express and concretise ideas XML as reflect on solutions by providing explanations cognitive tool produce a coherent research design Ø management (work packages, planning) structure the work for planning, communication, reflection and resourcefulness Ø meta-report (meta-cognitive scaffolding) reflection to engage in learning enhance learning by monitoring understanding Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001

EVA_paper ML Markup Language for project’s final paper Ø about the final product (summary, intro, body, conclusions, etc. ) scaffolding to writing a paper express and concretise ideas reconstruct learning meta-reflect on the result(s) by providing explanations produce a coherent research review focus on text, distract attention from decoration Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001

The editing toolset Editor in favor & style sheets Ø editors in favor (? ) XMetal for Microsoft users ($$$) epc. Edit for all platforms ($$$) XEmacs for rare cases : ) Ø style sheets for project and paper (multiple views) from one xml file from a combination of xml files with or without discussion Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001
comm. Ncontrol & tools EVA’s web portal for the projects (for tutors, students, guests) Ø monitor, share & visualize information through the portal that parses XML information Ø motivate with peering through awareness tools Ø promote collaboration & scaffold interaction with tutor(s) through discussion tools & mailing lists Ø facilitate group editing through a versioning system (file transfer tools and file locking) Ø facilitate tutor’s evaluation(s) through the evaluation tools (audits & final evaluation) Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001
comm. Ncontrol ex. (merci nathalie & Yves : ) Configuration according to authentication tutor student Mailing lists Visualise Awareness complete. Tools files Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001
Virtual Book EVA’s web portal for the papers Ø concretise students work by seeing it as a part of a virtual book Ø distribute results (peer benefits) through the portal that parses XML information Ø searchable information by being structured Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001
Development method Co-operative prototyping Ø with STAF-18 mostly Evolution of comm. Ncontrol Evolution of Virtual Book Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001
Implementation Ø XML Infoset Grammars: 2 major DTD’s (as cognitive tools), 4 minor (for data storing) & 1 reused (ibtwsh 6. dtd) XML files: 4 major (to structure semantics), 4 minor(to store data) XSLT: 7 stylesheets (to visualize) Ø Cocoon (Apache XML Project) it’s XSL processor to transform to HTML & XIncludes (to merge) Ø Java 8 Java servlets 2 Java classes reuse & modification of a DOMWriter import of an O’Reilly class Ø SAX & DOM API to parse XML files & update them Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001
Testing & Evaluation Ø Evaluation = Prototyping Group: 12 students STAF-Gina for STAF-18 Steps: Choose project - course - presentation - explanation follow phases - edit XML - coaching - finish - questionnaire Ø Evaluation of the LE (Learning Environment) general approach: good & encouraging grammar : quite mature toolset: useful & stable scripting code usability of the online interface: can be improved XML editing: remains difficult & challenging objective Ø Evaluation of the student learning Fairly good: Students manage to make a simple research plan Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001
initiate inquiry Conclusions direct investigations Initial goal Develop a constructivist environment and method to scaffold students projects through all it’s phases. manage time knowledge on project design team management promote reflection distribute to bigger audiences scaffold tutors role verify whether knowledge was acquired Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001 motivate …
Perspectives Ø Interesting method needs more testing (bigger/different classes - better XML editor) interface can be improved thanks to feedback gathered Ø Wishing list for future versions of EVA_pm easier editing better interface of comm. Ncontrol more interaction features possibility to configure the grammars make EVA_pm a Web archive (a servlet 2. 3 compatible *. war distribution) to make it completely portable Vivian SYNTETA, TECFA Workshop, Les Avants (Montreux), 12 -14/9/2001
