How Do I Get My Students Over Their Alternative Conceptions (Misconceptions) for Learning?
Removing barriers to aid in the development of the student

When teachers provide instruction on concepts in various subjects, they are teaching students who already have some pre-instructional knowledge about the topic. Student knowledge, however, can be erroneous, illogical or misinformed. These erroneous understandings are termed alternative conceptions or misconceptions (or intuitive theories). Alternative conceptions (misconceptions) are not unusual. In fact, they are a normal part of the learning process. We quite naturally form ideas from our everyday experience, but obviously not all the ideas we develop are correct with respect to the most current evidence and scholarship in a given discipline. Moreover, some concepts in different content areas are simply very difficult to grasp. They may be very abstract, counterintuitive or quite complex. Hence, our understanding of them is flawed. In addition, things we have already learned are sometimes unhelpful in learning new concepts/theories. This occurs when the new concept or theory is inconsistent with previously learned material. Accordingly, as noted, it is very typical for students (and adults) to have misconceptions in different domains (content knowledge areas). Indeed, researchers have found that there is a common set of alternative conceptions (misconceptions) that most students typically exhibit. There is one class of alternative theories (or misconceptions) that is very deeply entrenched. These are “ontological misconceptions,” which relate to ontological beliefs (i.e., beliefs about the fundamental categories and properties of the world).

Description of some of these common alternative conceptions (misconceptions)  and ontological misconceptions in different subject areas.

Alternative conceptions (misconceptions) can really impede learning for several reasons. First, students generally are unaware that the knowledge they have is wrong. Moreover, misconceptions can be very entrenched in student thinking. In addition, new experiences are interpreted through these erroneous understandings, thereby interfering with being able to correctly grasp new information.  Also, alternative conceptions (misconceptions) tend to be very resistant to instruction because learning entails replacing or radically reorganizing student knowledge. Hence, conceptual change has to occur for learning to happen. This puts teachers in the very challenging position of needing to bring about significant conceptual change in student knowledge. Generally, ordinary forms of instruction, such as lectures, labs, discovery learning, or simply reading texts, are not very successful at overcoming student misconceptions. For all these reasons, misconceptions can be hard nuts for teachers to crack. However, several instructional strategies have been found to be effective in achieving conceptual change and helping students leave their alternative conceptions behind and learn correct concepts or theories.
