I've been teaching 7th and 8th grade Television Broadcasting for almost a decade now, and I use rubrics on a daily basis! The rubric is based upon a 4 point grade scale using the modifiers "Advanced", "Proficient", "Basic", and "Below Basic".
Unlike my News Segment Rubric that is more specific, this rubric can be used as a general rubric for any student video or advanced PowerPoint presentation.
Please feel free to contact me with any questions or concerns!
