Recent research suggests that a major obstacle to evolution understanding is an essentialist view of the biological world. The present study investigated the effects of formal biology instruction on such misconceptions. Participants (N = 291) completed an assessment of their understanding of six aspects of evolution (variation, inheritance,…

The connection between the molecular-level structure of a substance and its macroscopic properties is a fundamental concept in chemistry. Students in college-level general and organic chemistry courses were interviewed to investigate how they used structure-property relationships to predict properties such as melting and boiling points. Although…

Introduction: The purpose of the study presented here was to understand and describe the misconceptions of students with visual impairments about sound and instructional techniques that may help them to develop a scientific understanding. Methods: Semistructured interview-centered pre-and posttests were used to identify the students' conceptual…

The purpose of this paper is to present a comprehensive, accessible and strategic overview of what is currently known about school and system reform in the early twenty-first century. It reflects on the knowledge that has been acquired from research, policy and practice over the past three decades and presents it in a way that provides frameworks…

Patient's nonadherence to treatment is one of the most serious issues for modern medicine. WHO experts in the guideline [6] thoroughly analyze the reasons for poor adherence to long-term therapy and outline a wide range of factors influencing adherence to long-term therapy. At that it is emphasized that none of those factors is decisive. It…

The primary objective of this project was to learn what effect a computer program would have on academic achievement and attitude toward science of college students enrolled in a biology class for non-science majors. It became apparent that the instructor also had an effect on attitudes toward science. The researcher designed a computer program,…

Information on the HIV/AIDS epidemic in Southern Africa is often interpreted through a veil of secrecy and shame and, I argue, with flawed understanding of basic statistics. This research determined the levels of statistical literacy evident in 316 future Mathematical Literacy teachers' explanations of the median in the context of HIV/AIDS…

Molecular visualizations have been widely endorsed by many chemical educators as an efficient way to convey the dynamic and atomic-level details of chemistry events. Research indicates that students who use molecular visualizations are able to incorporate most of the intended features of the animations into their explanations. However, studies…

This article analyzes the perceptions of Spanish health professionals, children with Tourette's Syndrome (TS) and their parents about social, school and family problems related to the disorder. A qualitative research methodology was used involving Focus Groups (FGs) made up of children with TS (× 2 FGs), parents/caregivers of persons with TS (× 2…

In response to the wide-scale proliferation of "the cone of learning"--a fanciful retention chart confounded with Dale's Cone of Experience--the authors make four major claims debunking this fantasy and provide documentary evidence to support these claims. The first claim is that the data in the mythical retention chart do not make…

The present study sought to reveal how elementary teachers develop their engineering pedagogical content knowledge (PCK) after leaving professional development programs to practice engineering teaching in real classroom settings. Participants of this study were the elementary teachers who received one-week training of engineering education…

Over the last 20 years, science education studies have reported that there are very different understandings among students of science regarding the key aspects of climate change. We used the cognitive linguistic framework of experientialism to shed new light on this valuable pool of studies to identify the conceptual resources of understanding…

In France, most teachers still receive scant training in how to support plurilingual children in their learning of and through the language of instruction. In the absence of relevant, in-depth knowledge about language, we believe that many teachers are practising language policies based on beliefs rooted in ideologies unsupported by research…

Korean American students experience invisibility and silence as their culture and presence remain outwardly invisible in the mainstream culture of US high schools. This is further exacerbated by the silent response of the dominant population of the school towards these issues. Yet, to an extent, Korean American students find a sense of comfort…

This paper offers an examination of gay-straight alliance (GSA) members' engagement with sex education, sexual health, and prejudice and discrimination in Canadian public high schools. It explores how five students' (four straight and one gay-identifying) participation in GSAs served as a springboard for learning about and challenging stereotypes;…
