Hi Sonja. I checked your blog and found it interesting, specially your questions about how to develop social responsibility. I gave you my ideas, hope you can read them. Internships is always I like to consider for classes, and they could keep an online diary based on their experience. Students could also reflect on their own personal growth. We can keep "blogging"
Voxopop is a web based audio tool that enables users to record their speaking for others
to listen and respond to. It allows teachers and students to build up threaded audio
discussions online similar to those on a text based bulletin board. You can even open a private talkgroup (which is like a virtual classroom where only you and your students participate). It may not be the perfect solution for Speaking activities, but you'll probably find it pretty useful for your teaching purposes.
