For something to have educational value, it generally needs to have several components in place.
- Learning Objectives
- Learning Outcomes
- A Lesson Plan
- Introduction
- Background Material
- Instruction/Lesson
- Activity
- Feedback Mechanism
- Review/Repeat
There has to framework, i.e ROPES method, etc.
Television is far too passive and is a one-way form of communication. If you want television to be somewhat an educational experience, a parent should watch the show with the child and ask questions, "what is the character doing?", "Are they being good or bad?", "What are they baking?" with follow up, "What goes into an apple pie?". For this to work, the parent would need to have the ability to stop and rewind the program back to inquire and review.
In addition, there needs to be a means of establishing learning scaffolds for the kids. Were something is built upon from week to week. If I was to teach a child to do read, the foundation would be the alphabet and word association. A is for apple for example. Recognizing the letter and the sound it creates.
Most of the programs do not deal with reading, but with concepts such as sharing. However, the story arc of a cartoon does not have the mechanism to a build a learning scaffold for the concept and then have an activity. Television is too passive a means of delivery. Now if Dora and Blues Clues there are some pauses for kids to give "answers" but there is no means of saying whether or not the answer is correct. Generally, if correct - continue activity, if not - repeat foundation. So if the child has the concept or idea of sharing, then it is time to have children demonstrate sharing i.e. asking - giving - sharing, maybe introduce manners, say "thank you" for getting an item from another child. What are possible positive outcomes, what are possible negative outcomes? Child does share, child does not share.
Sesame Street follows some of the rules, especially when a given show
is "brought to you by" a letter and a number. This is the review but not really. Dora has a review, but it to lacks many educational elements.
Adult television is informative - news, discovery channel. Or entertainment - movies, sitcoms.
