Misconceptions Response

It was interesting while reading this article that high school and college students had trouble labeling how the objects would fair in water.  It never occurred to me that students who should be taught the same concepts in each grade would have misconceptions about that concept.  It was also interesting that students who have been taught the concepts over and over again skill have the same misconceptions about the concept.  My only reasoning for this is that once the students learn it once and hear it again they automatically refer back to their previous knowledge and if it doesn't confirm what they know then they reject it.  I personally feel that a ton of the misconceptions people have about a concept has to deal with the way in which they learned the concept.  I feel that if the student was lectured on and did not have an opportunity to engage in what was being taught then they have a higher probability of storing the information wrong.  This article helped confirm my belief that we have to always keep in mind what the students bring to the table instead of where they are projected to be at.  As teachers we have to uncover the misconceptions that the students might have stored into their memory.
