Models are crucial to science teaching and learning, yet they can create unforeseen and overlooked challenges for students and teachers. For example, consider the time-tested clay volcano that relies on a vinegar and-baking-soda mixture for its "eruption." Based on a classroom demonstration of that geologic model, elementary students may interpret…

Epilepsy is the most misunderstood of all neurological disorders known to man. Even though modern medicine (a very recent development in human history) learned that epilepsy was a common variation in biology, the roots laid down by centuries of misunderstanding have yet to be pulled from the society's social consciousness. While medicine and now…

Students' misconceptions before or after formal instruction have become a major concern among researchers in science education because they influence how students learn new scientific knowledge, play an essential role in subsequent learning and become a hindrance in acquiring the correct body of knowledge. In this paper some students'…

The need for determining a common language for discussing misconceptions amongst the educators, classroom teachers and educational researchers which will assist in uncovering the misconceptions is discussed. It is seen that the misconceptions of the students could be considered as a diagnostic information that assists in finding out different ways…

An experienced secondary teacher shares some common misconceptions about literary analysis. The activities, which help the students to practice theory and read drama, poetry and fiction, are described.

This article identifies ways professionals perpetuate misperceptions about mentoring when engaging in traditional methods of mentoring. Fassinger's feminist model of mentoring is expanded by incorporating multicultural elements into the model. The authors' definition of "multiculturalism" is inclusive of individuals from different races,…

Many students, when they take an elementary differential equations course for the first time, bring with them misconceptions from numerical methods that they had learnt in their calculus courses, most notable of which concerns the mesh width in using a numerical method. It is important that we strive to dispel any of these misconceptions as well…

A simple blind spot activity has been devised to help students discard misconceptions about image formation by lenses. Our hands-on experiment, in which students determine the location and size of their blind spots, is suitable for various age groups at different educational levels. The activity provides an opportunity to teach students how to…

Health educators play a key role in assisting the nation deal with and be prepared for potential biological attacks. This article summarizes information found in the literature about likely bioterrorist threats to the U.S. population and discusses the responsibilities of health educators in regard to these threats. Among the important roles health…

We present and discuss three examples of misapplication of the notion of conditional probability. In each example, we present the problem along with a published and/or well-known incorrect--but seemingly plausible--solution. We then give a careful treatment of the correct solution, in large part to show how careful application of basic probability…

Prior research has shown that students consistently overestimate their performance on academic exams, with the error being inversely related to their grades. The effect has been explained as a matter of competency. If true, then students who do not know what they do not know are put in a double bind. They do not have the cognitive ability to…

According to Alan Slonsom, "Mathematics without proof is like brandy without alcohol: the spirit of the subject is missing." This author relates how she became motivated to pick proof as an exciting topic to teach. It is important to distinguish between the usage of the word "proof" in everyday life and its meaning in a mathematical context.…

This article illustrates the misconceptions that students have when using the equals sign and describes a lesson used to give students the foundation for an accurate conception of equivalency.

Several myths have grown up around problem solving as a result of the manner in which problem solving has traditionally been taught in schools. These myths are harmful to children, they affect curriculum decision of teachers, distort discussions about problem solving and undermine the mathematics reform movement in general.

This review is an exploration into whether classroom methods similar to those applied by K-12 teachers are valid for adults and can be successfully applied to classrooms for disadvantaged adults: specifically, journal writing as a tool for improving learning and classroom relationships. The literature dispels the myth that teaching adults differs…
