Scientific misconceptions

Scientific misconceptions

= Types of scientific misconceptions =

In general, scientific misconceptions have their foundations in a few "intuitive knowledge domains, including folkmechanics (object boundaries and movements), folkbiology (biological species configurations and relationships), and folkpyschology (interactive agents and goal-directed behavior)" (Altran & Norezayan, 2005), that enable humans to interact effectively with the world in which they evolved. That these folksciences do not map accurately onto modern scientific theory is not unexpected. A second major source of scientific misconceptions are instruction-induced or [http://en.wikipedia.org/wiki/Didaskalogenesis didaskalogenic] misconceptions.

Misconceptions can be broken down into five basic categories 1) preconceived notions; 2) nonscientific beliefs; 3) conceptual misunderstandings; 4) vernacular misconceptions; and 5) factual misconceptions (e.g., Committee on Undergraduate Science Education, 1997).

While most student misconceptions go unrecognized, there has been an informal effort to identify errors and misconceptions present in textbooks. The [http://www.ems.psu.edu/~fraser/BadScience.html Bad Science] web page, maintained by Alistair Fraser, is a good resource. Another important resource is the [http://www.ipn.uni-kiel.de/aktuell/stcse/stcse.html Students' and Teachers' Conceptions and Science Education] (STCSE) website maintained by Reinders Duit. Another useful resource related to chemistry has been compiled by [http://www.rsc.org/education/teachers/learnnet/miscon.htm Vanessa Barker]

A more systematic search for student misconceptions has been driven by recent efforts to construct concept inventories relevant to various disciplines.

Addressing student misconceptions

A number of lines of evidence suggest that the recognition and revision of student misconceptions involves active, rather than passive, involvement with the material. A common approach is through metacognition, that is to encourage students to think about their thinking on particular problem. In part this requires students to verbalize, defend and reformulate their understanding - essentially a Socratic method. Recognizing the realities of the modern classroom, a number of variations have been introduced. These include Eric Mazur's [http://mazur-www.harvard.edu/research/detailspage.php?ed=1&rowid=8 Peer Instruction] , as well as various tutorials in physics developed groups at [http://www.phys.washington.edu/groups/peg/tut.html University of Washington] and the [http://www.physics.umd.edu/perg/abp/ University of Maryland] .
