Using Technology in my classroom, especially for content that may be difficult for students

I hope that using MS Movie-Maker to create movies and podcasts will enable me to more effectively teach some difficult concepts to all my students, but especially those that need extra help or instruction to grasp new material. One idea that I would like to explore is having students create tutorial movies or podcasts over specific content that could be used by any student who needs extra help. Of course, I would need to preview them before they could be used.

I plan to research podcasts that have already been created to supplement what I present in the classroom. Also, I require my students to find a science current event weekly--using iTunes podcasts as a source would allow them to use technology that they are familiar with.
