CLear: Goal: 

CLear: Goal Overall Goal: To support learning teams by computer-supported cooperative learning environments (CSCL), and to develop cooperative learning methods that are appropriate for distributed cooperative learning Focus: adult learners, teams in companies/organizations Support for various learning scenarios: Synchronous and asynchronous learning co-located and distributed teams individual and group learning How can distributed groups/teams learn effectively?

VITAL: crucial discussion: 

VITAL: crucial discussion pro: various possibilities of cooperation space to develop creativity contra: weak support for unexperienced learners weak support for authors/ tutors approach: searching for the solution by analysing the advantages of Explorative Learning and Guided Tours

Explorative Learning: 

Explorative Learning

Explorative Learning: 

Explorative Learning Advantages: Exploration of self-chosen topics Self-determined learning methods Free navigation through the learning material Incidental learning Various forms of interaction Additional impact: rational discourse, writing skills, problem solving techniques Problems: “lost in hyperspace” Lack of navigation support and orientation Not suitable for unexperienced learners

Guided Tour : 

Guided Tour

Guided Tours: 

Guided Tours Advantages: Pre-defined learning goals Pre-structured learning material Presentation of content in small steps Introduction, summary, and repetitions in each module Reinforcement by frequent feedback Problems: Limitation for active learners Lack of creativity Strongly guided = “drill & practice”

Dialectic Conclusionectic Conclusion: 

Dialectic Conclusion ectic Conclusion Free navigation, but a central point of orientation Requirements: Meta-information on content structure didactical structure Interaction support
