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".
This is one of my favorite rubrics in that it is so versatile! Students are graded not only on their finished product, but also on their planning and production skills.
Please feel free to contact me with any questions or concerns!
