THere is never, even in a wealthy enviroment, enough time, equipment, or whatever to let students make any more than trivial choices in experimental design
We have art classes in which there's plenty of time for the students to create artwork. In a similar context there no reason why there shouldn't be experimention classes that teach students to experiment and give them plenty of time for the exercise.
School wastes massive amounts of time by teaching facts without SRS that get forgotten by the students a few years after they take the class. Learning the paradigm of experimentation might be more important then teaching the way the periodic table is arranged.
We have art classes...no reason why there shouldn't be expermentation classes.
In high school, most studio art classes have a lot less time devoted to verbal learning or whatever and much more to practice. Plus mundane art materials are both inexpensive and very safe to use. (and may already be in the classroom. Much can be taught with pencil sketches.) Chemistry (especially with modern-day, possibly excessive safety consciousness) is not, and requires more specialized space and has a hard time admitting of experimental design by students beacause they ...
As a teacher, I wonder if it is possible to instill this skill into students the skills of rationality and critical thinking. I teach the third grade, and it is not immediately apparent how to apply this with my own class.
The problems I foresee are as follows:
In the sequences, it is suggested teachers should drill into students words don't count, only anticipation-controllers. How practical is this for an elementary school level? Also appreciated would be any ideas or experiences on how to do this, or how to combat the above problems. Hearing from other teachers would be excellent especially.
