Using ICT to Learn About Parts of Speech

As an activity for the online course I am taking on ICT in primary education I was asked to brainstorm the ways I could use technology for students to learn something in particular, considering the "Learning Types" developed by Diana Laurillard in her book "Teaching as a Design Science: Building Pedagogical Patterns for Learning and Technology" (I just bought a sample of this book, looks interesting!)

I purposefully tried to choose a topic that would typically be taught in a very boring, classical, text-booky way, to see how easy it would be to change it.

The topic I chose was different parts of speech (for 11 year old english language  learners) (this topic is actually part of a Unit of Inquiry I am currently developing, where I want students to understand this central idea: Each part of speech has a function and they work together to create complete sentences of different types. "Different parts of speech" is actually the content from one of the lines of inquiry: an inquiry into what different parts of speech are like (Form). I will post about this unit later when I have worked on it more, but any suggestions are welcome!).

The course suggested us to use this template to think about how technology could help students understand any given topic, and here is my brainstorm:

Learning through:	Students learning about different parts of speech could....
Acquisition	Student’s could watch a video about an everyday conversation or about of topic of their liking.
Discussion	Students could use Voicethread to attach their comments to the video they watched, mentioning the parts of speech they were able to identify.
Investigation	In order to identify all the parts of speech in the video they watched, so that they can comment on them on Voicethread, students could research parts of speech definitions online.
Practice	Students could practice by recording their own discussions or conversations where they intentionally use and point out different parts of speech.
Collaboration	Students could share their Voicethreads with each other so that they can continue adding their comments to point out parts of speech that others may have missed in the video.
Production	Students could choose their best recordings and edit these to create a short video that showcases their conversation while pointing out the parts of speech that were used.

What do you think about these ideas? Do you have experience using Voicethread or other similar apps with students? Do you have any suggestions?
