Flow patterns (e.g., Pyramid or Snowball) formulate good practices to script
collaborative learning scenarios, which have been experimented in small-scale settings
widely. Applying flow patterns on large-scale contexts present challenges to educators in
terms of orchestration load. Orchestration technology can support educators to manage
collaborative activities; yet existing technology do not address flexibility challenges like
accommodating growing numbers of students or tolerating dynamic conditions in learning
settings. We define elasticity and dynamism as two key elements in the flexibility of a script.
Elasticity is related to the capacity of an orchestration technology to incorporate varying
participant counts. Dynamism is the capacity to maintain a pedagogically meaningful script
progression in presence of different individual behaviors. In this paper we propose flow
creation and flow control mechanisms to address elasticity and dynamism in orchestration
technology for Pyramid flows. These mechanisms, implemented in the PyramidApp tool, have
been evaluated across four scenarios varying from small to large settings. The results show
that rules enabling pyramid creation on-demand and the use of timers are useful to achieve
elasticity and dynamism in the pyramid formation and progression in an automatic manner. |
