The aim of this paper is to present the nature of preservice secondary mathematics teachers' knowledge of students as emerged from a study investigating the development of their pedagogical content knowledge in a methods course and its associated field experience. Six preservice teachers participated in the study and the data were collected in the…

Objectives: To examine associations between weight misperception and youth health risk and protective factors. Methods: Three thousand ten US seventh-graders (72.1% white, mean age: 12.7 years) self-reported height, weight, risk, and protective factors. Analyses were conducted to determine cross-sectional and longitudinal associations between…

America's 2.5 million Muslims make up less than 1 percent of the U.S. population, according to the Pew Research Center. Anecdotally, educators know that many Muslim students face discrimination. Unfortunately, no group or government agency keeps statistics on the subject. But some cases have warranted investigation by the U.S. Department of…

The purpose of this study was to investigate the pre-service teachers' conceptions about the limit of same partial functions given in the form of both graphical and symbolic, the misconception that the pre-service teachers have the concept of limit, and whether there were any differences between pre-service teachers' algebraic performance and…

There is ongoing interest in how and what we teach in physics courses for non-science students, so-called "physics for poets" courses. Art Hobson has effectively argued that teaching science literacy should be a key ingredient in these courses. Hobson uses Jon Millers definition of science literacy, which has two components: first, "a basic…

For over 50 years, "seven plus or minus two" has been a commonly used guideline for gauging how many chunks of new information should be presented at one time in learning and performance situations. Often cited as the limit of working memory, this guideline was created as a result of misinterpreting an article by Miller (1956). More recent studies…

The purpose of this study was to investigate the prevalence of misconceptions, dogmas and popular views about giftedness and intelligence among Turkish lay people. A survey questionnaire consisting of 12 forced-choice items about global misconceptions, dogmatic beliefs and popular views related to giftedness and intelligence was used to collect…

This article offers a particular analytic method from systemic functional linguistics, "thematic analysis," which reveals the mathematical meaning potentials construed in discourse. Addressing concerns that discourse analysis is too often content-free, thematic analysis provides a way to represent semantic structures of mathematical content,…

Much research has been published that describes the misconceptions students have about gases; however, not much research has been published that suggests how to change these misconceptions. The action research presented in this article examined how using laboratories to contradict students' preconceived ideas would affect their learning. High…

General practitioners (GPs) could have an important role in early diagnosis of autism. There have been no studies evaluating the knowledge of GPs regarding autism in Pakistan. We aimed to fill that gap by assessing knowledge and attitude of GPs in Karachi regarding autism. We conducted a cross-sectional survey of 348 GPs; only 148 (44.6%) had…

This paper is birthed from my lifelong experiences as student, teacher, administrator, and researcher in urban science classrooms. This includes my years as a minority student in biology, chemistry, and physics classrooms, 10 tears as science teacher and high school science department chair, 5-years conducting research on youth experiences in…

As elementary school students attempt to understand mathematical concepts, engaging in the processes of reasoning and sense making is important. To do so, students should be expected to listen to and challenge their classmates' ideas. Disagreements provide students with the impetus to think deeply about mathematics in an effort to make sense of a…

Developing an understanding of place value and the base-ten number system is considered a fundamental goal of the early primary grades. For years, teachers have anecdotally reported that students struggle with place-value concepts. Among the common errors cited are misreading such numbers as 26 and 62 by seeing them as identical in meaning,…

Problem Statement: Difficulties in the learning process usually emerge from the problem of mental representations constructed by students in their interactions with the world. This previous knowledge and these ideas are in contradiction with scientific facts, and are known as misconceptions or alternative ideas. Thus, an analysis of the mental…

Careful examination of the discipline gap reveals growing disproportionality in the use of exclusionary discipline measures with female students of color, particularly African American females. Most often, adolescent girls of color are disciplined for subjectively defined behaviors, or behaviors considered inappropriate by educators. This study…
