Teaching is an interactive process in which teachers gather information, analyze the results, and construct a response based on this diagnosis (Cooney, 1988). Considering alternatives in constructing a response, that is, making an instructional decision, is of great importance in teaching. How might mathematics teacher educators provide…

The existence, preponderance, and stability of misconceptions related to evolution continue as foci of research in science education. In their 2006 study, Geraedts and Boersma question the existence of stable Lamarckian misconceptions in students, challenging the utility of Conceptual Change theory in addressing any such misconceptions. To support…

Determination of conceptual problems which may cause alternative conceptions in science and technology textbooks is significant to increase in success of pupils and teachers. It is a vital issue to arrange books in a way removing or decreasing these faults in order to improve a better education via textbooks. This study aims to determine…

Adolescents with moderate disabilities are not being given vital information regarding their sexuality and ways to behave responsibly with their peers. This article examines the laws that govern the education of all persons with disabilities, how societal norms and attitudes have contributed to this lack of sexuality knowledge, how these…

Many students fail to develop a conceptual understanding of organic chemistry. Evidence suggests this failure goes hand-in-hand with a failure to grasp the techniques, meaning, and usefulness of curved arrow notation. Use of curved arrow notation to illustrate electrophilic addition appears to be a critical juncture in student understanding.…

In the April 2009 edition of "Exceptional Parent," Part One of this series explored why, for their own emotional well-being, it is so important for parents to tell others about their or their child's epilepsy. This month's installment will discuss the basics of how to reveal epilepsy to others, including some additional advantages one receives in…

This study investigated introductory calculus students' spontaneous reasoning about limit concepts guided by an interactionist theory of metaphorical reasoning developed by Max Black. In this perspective, strong metaphors are ontologically creative by virtue of their emphasis (commitment by the producer) and resonance (support for high degrees of…

Acceleration is a fundamental concept in physics which is taught in mechanics at all levels. Here, we discuss some challenges in teaching this concept effectively when the path along which the object is moving has a curvature and centripetal acceleration is present. We discuss examples illustrating that both physics teachers and students have…

While Merrifield is correct in his basic argument that so-called "market reforms" in el/sec schooling are far from being pure market, he is incorrect to suggest that purer market projects are needed together with simulations of pure market reforms. There are two fundamental problems in that thesis. First, it is not clear that school choice in…

There is a fallacy about identifying gifted and talented children and youth that refuses to go away: It is the notion that a single score is "sufficient" for determining giftedness. In this article, the author addresses several reasons for the longevity and ubiquity of this myth, as well as the data that call the myth into question. These include…

Curriculum myths rise and fall based on contemporary educational and societal contexts. Twenty-five years after the first discussion about the myth of a single curriculum for the gifted, the myth is still prevalent. Its viability as a myth is a consequence of the current educational climate rather than empirical evidence that is gathered and used…

Many people fear that play-fighting or rough and tumble play is the same as real fighting. There is also a fear that this rough play will become real fighting if allowed to continue. Most of all, parents and teachers fear that during the course of rough and tumble play a child may be hurt. To provide for and allow children to play rough without…

People who follow trends in higher education are aware of a renewed emphasis on religious plurality and spirituality on college campuses. But all the articles, conferences, and campus activities surrounding religion and spirituality rarely, if at all, acknowledge one group: students who are atheists. If colleges are to be truly inclusive, they…

Data from 154 interviews with students in grades 3 to 13 were analyzed to suggest a developmental progression of conceptual understanding associated with the sample space for two ordinary six-sided dice tossed simultaneously. The model was then considered in the light of responses to an extension task involving three six-sided dice with four sides…

Submicrorepresentations (SMR) could be an important element, not only for explaining the experimental observations to students, but also in the process of evaluating students' knowledge and identifying their chemical misconceptions. This study investigated the level of students' understanding of the solution concentration and the process of…
