Walking with ADDIE: What Is and Isn’t Taught

Imagine you asked your friend to recommend a brand to look for when buying a new TV. Imagine that your friend came up with a list of two to three options, just for this example; lets say she/he said, “I would recommend LG, Samsung and Sony.”

What do you learn from this recommendation? Well the easy answer would be that your friend likes LG, Samsung and Sony. Thats it, right? Your friend didn’t say anything else so that is all you can take from your quick conversation. The problem is, thats not all that you can get from the recommendations. Your friend, while not mentioning brands like Panasonic, Sharp and Vizio, made a non-recommendation of those brands. You just learned the same amount about those brands as you did LG, Samsung and Sony.

This issue is also present when developing a curriculum. You have to be aware of what is being said and what is not being said. What isnt being taught is just as important as what is being taught. In fact it may even be more important. What isnt being taught can be viewed as unimportant or irrelevant.

When planning a curriculum you have to be conscious about what is and what isnt talked about. That doesnt mean that every topic has to be covered. The non-mentioned topics become a part of the “null curriculum.” What isnt taught is also teaching and that must be taken into account. What that means is by mentioning the topics that are not covered in detail; it may be enough to raise the felt importance of those topics.

In the example from the beginning if the statement was changed to, “The best three are LG, Samsung and Sony while Sharp and Vizio are right below them. I dont know anything about Panasonic or any of the other brands.” Now you know more about the other brands and that just because your friend didnt mention Panasonic, it doesnt mean they are a bad brand.
