MISCONCEPTIONS CIA

 

Review video “A Private Universe”.

 

            Discuss misconceptions in science.

 

            Come from:

                                    Real World Experiences (example: friction)

                                    Bad diagrams. (example: earth orbit)

                                    Abstractions/Generalizations/Simplifications. (example: living things move, rocks are either metamorphic or igneous, a substance is a solid or a liquid)

                                    Analogies: (electricity as water)

                                    Models: (electrons go in orbits)

Vocabulary without context, different scientific meaning

“energy makes it go” “glaciers retreat”

                                    Sayings/myths “lightning never strikes twice in the same place”

                                    Plain bad facts. (evolution is impossible, heavier things fall faster)

 

Links to research on constructivism: how students learn science. They use their own experiences to construct their meaning and model of explanation of the world. Despite our “teaching”, students revert back to their models even if they have memorized ours. To overcome their deep misconceptions

 

-They must become dissatisfied with their existing conditions. (why is my explanation wrong?)

-The scientific conception must be intelligible. (Oh, this makes sense)

-The scientific conception must appear plausible. (This agrees with my experiences)

-The scientific conception must be useful in a variety of new situations. (I can use this to predict things)

 

If teachers are to improve students' science conceptions we must recognize that:

-students come to science class with ideas,

-students' ideas are often different from scientists,

-students' preconceptions are strongly held,

-traditional instruction (rote learning) will not lead to substantial conceptual change, and

effective instructional strategies enable teachers to teach for conceptual change and understanding.

The key to altering the ideas, explanations, and conceptions of science that students possess is to find out and use what students already know. The challenge of teaching science is to ensure that you do not leave intact students' alternative conceptions or fill students with ideas and explanations which have little chance of being understood.

 

“While growing up, children are told by adults that the "sun is rising and setting," giving them an image of a sun that moves about the earth. In school, students are told by teachers (years after they have already formed their own mental model of how things work) that the earth rotates. Students are then faced with the difficult task of deleting a mental image that makes sense to them, based on their own observations, and replacing it with a model that is not as intuitively acceptable. This task is not trivial, for students must undo a whole mental framework of knowledge that they have used to understand the world.”
