Let the student explore and search consciously the variables to be considered before reaching a decision or solving a problem:

Example 1: A young married couple decides to buy a table. They go to a furniture shop and, without thinking much of it, they decide to buy one of American colonial style they liked. When they come home with the table, they realize that it does not fit through the door, nor the window, nor the balcony.

What do you think happened to this couple? Why did they reach that situation?

Cases as this are frequent in daily life. What conclusion do you make of the example?

How could the problem of the couple have been avoided?

Example 2: What variables need to be considered to plan for a field trip?

Example 3: What variables need to be considered to watch television?


Anticipate what could happen, in the short and long terms.

Problem 1: Consider the immediate and medium-term consequences, of the invention of the gas engine.

Problem 2: What could be the short and long-term consequences of using computers in education activities?


Direct attention to what you wish to accomplish and clarify the intention of actions and thoughts.
