The Designs:

Problem-based Learning
Problem-based learning builds a lesson around a central question that requires the students to either solve a problem or make a decision.

Roleplaying
"Walking in the shoes of others" - a role play involves each student playing our a role in a given scenario.

WebDilemma
This has many of the inquiry learning benefits of a WebQuest but is less technically demanding to design as it is more simply structured.

WebQuests
A WebQuest is an inquiry-oriented lesson format in which most or all the information that learners work with comes from the web.

Predict-Observe-Explain
Student predict what they think will happen in a scenario, then observe what really happens, and explain what they see and how it relates to their prediction.

Digital Storytelling
Digital stories are multimedia narratives that are usually short and personal.

De Bono's APC
De Bono's APC (Alternatives, Possibilities, Choices) approach. Instead of simply making a judgement, it is advisable to search for the "not so obvious" solutions after considering all the possibilities, which will provide you with a more complete picture. 

De Bono's CAF
De Bono's CAF (Consider All Factors) approach. Instead of simply jumping to a conclusion, it is advisable to consider multiple factors or options. 

De Bono's C & S
De Bono's C & S (Consequence and Sequel) approach. Instead of simply jumping to a conclusion, think about an action and its possible short, medium and long-term consequences.
