Student Generated Vocab Lists?

I'm in the process right now of researching Student-Generated Vocab lists. This is the first opportunity I've had to do this since I normally teach a common curriculum; however, for my upper level Spanish class this year we have a very flexible course map. 

I provided my students this past quarter with textbook-generated vocab lists; however, next quarter I plan to have these more student-generated.  Here are the two articles I'm reading at the moment.

Can't wait to try these in a few weeks!

Interview Project Padlet

Here is the current Padlet of my Spanish 4/5 Interview Project.

As you can see, as the Vocaroo, One Drive, or Google Drive links come in, I copy and paste the link onto a Padlet post with the student's name.

On Monday, I will share the link with my students and they will have to listen to three presentations of their choice, and respond to reflection questions --who was the interviewee, how was the language of the presentation, and what content did they find the most surprising.
