As biotechnology-related scientific advances, such as stem cell research (SCR), are increasingly permeating the popular media, it has become ever more important to understand students' ideas about this issue. Very few studies have investigated learners' ideas about biotechnology. Our study was designed to understand the types of alternative…

When students are asked to write original story problems about fractional amounts, it can illustrate their misunderstandings about fractions. Think about the situations students would describe to model 1/2 + 2/3. Three elements, in particular, challenge students: (1) Which of three models (region, or area; measure; or set) is best suited for a…

The "What's the "matter" With XOD" activity addresses students' misconceptions and refines their ideas about phases of matter. This activity introduces the characteristics for solids, liquids, and gases, and begins a discussion about physical and chemical changes and how matter can cycle through different phases. Depending on class size and…

In this paper, we describe animations and animated visualizations for introductory and intermediate-level quantum mechanics instruction developed at the University of St Andrews. The animations aim to help students build mental representations of quantum mechanics concepts. They focus on known areas of student difficulty and misconceptions by…

By examining the respective contributions of Karl Popper and Thomas Kuhn to the philosophy of science, the author highlights some prevailing problems in this article with the methods of so-called scientific research in education. The author enumerates a number of reasons why such research, in spite of its limited tangible return, continues to gain…

Parallels between martial arts and mathematics are explored. Misguided public perception of both disciplines, students' misconceptions, and the similarities between proofs and katas are among the striking commonalities between martial arts and mathematics. The author also reflects on what he has learned in his martial arts training, and how this…

This article investigates the optics misconceptions of 220 year 11 Thai high-school students. These misconceptions became apparent when the students attempted to explain how an object submerged in a water tank is "seen" by an observer looking into the tank from above and at an angle. The two diagnostic questions used in the study probe…

The article presents the results of a study that examined Palestinian physicians' misconceptions about abused wives and abusive husbands and the extent to which Palestinian physicians approve of wife abuse. Self-administered questionnaires were completed by 396 physicians. The results revealed that between 10% and 49% of the Palestinian physicians…

Does the person become the name or does the name become the person? This question was asked by a participant of my culture jam entitled, "What's my name?" In this culture jam, I asked people to discern the name of a person based solely on their appearance and a list of possible names below their picture. This article aims to show how culture jams…

Purpose: A picture is worth a thousand words. Multimedia teaching materials have been widely adopted by teachers in Physics, Biotechnology, Psychology, Religion, Analytical Science, and Economics nowadays. To assist with engaging students in their economic study, increase learning efficiency and understanding, solve misconception problems,…

Textbooks have a specific importance since they are used as the main instruction material. It is important to know that whether commonly used textbooks are adequate in terms of content and presentation. This study was performed to examine whether chapters on "photosynthesis" and "respiration" in the Biology-3 textbooks, that…

Science instructors have long known that the use of discrepant events with unexpected outcomes is a powerful method of activating thinking. A discrepant "teaching" event is similar to a discrepant science event in that it vividly portrays what is often an abstract construct or concept and has an unexpected outcome. The unexpected outcome creates…

From our teaching of the contractile unit of the striated muscle, we have found limitations in using textbook illustrations of sarcomere structure and its related dynamic molecular physiological details. A hand-held model of a striated muscle sarcomere made from common items has thus been made by us to enhance students' understanding of the…

Participation in rigorous high school courses such as Advanced Placement (AP[R]) Physics increases the likelihood of college success, especially for students who are traditionally underserved. Tackling difficult multiple-choice exams should be part of any AP program because well-constructed multiple-choice questions, such as those on AP exams and…

Fairness is often considered synonymous with equality: the equal treatment of people sharing a uniform description or role. This concept--"fair" means "equal"--has spawned the notion that it is fair to teach all children the same way. Put simply, if fairness means equality in family life, restaurant dining, and sports--not to mention in observing…
