The company I have worked in for the past 3 years has produced educational content very similar to this project, and more. I was involved in content writing, media production and content editing.
In my day job and freelance work I create and edit content with Articulate Storyline, Microsoft Office (PPT, Word, Excel), Adobe Creative Suite (InDesign, Illustrator, Photoshop), Protools, Audacity, GIMP, Inkscape etc.
I also have radio presentation and production experience, and I have produced online and broadcast quality content by doing my own sound and audio editing.
My skills: effectively bilingual (English and Mandarin Chinese) with experience in instructional design, content development, creative writing, communications and media, e-learning and ESL/EFL teaching.
I am also actively in touch with other educational content creators, developers and talent for different school subjects and languages, as well as continuing education for adults in various industries.
