Persuasive Writing: Student-Made Videos

I've recently been teaching Grade 9 English Language Acquisition - or ESOL if you prefer - in the IB MYP program. The four students have been with us between 2 and 6 months, so the are very much developing all their skills. 
Outcomes for our current unit include being able to plan and write a persuasive essay, so in a bid to make the elements as clear as possible, the four students each produced a video on one of the following topics: thesis statements, topic sentences, supporting details and elaboration. 
Before commencing on the project, they negotiated this rubric. 
See the results below and feel free leave comments on their blog; they'd love to hear your thoughts.
