Evolutionary history and structural considerations constrain all aspects of animal physiology. Constraints on invertebrate locomotion are especially straightforward for students to observe and understand. In this exercise, students use spiders to investigate the concepts of adaptation, structure-function relationships, and trade-offs. Students…

In this article we problematize the purpose of teaching science in preschool and the competences preschool teachers need in order to conduct science activities in the classroom. The empirical data were collected through an action research project with five preschool and primary school teachers (K-6). In the first section of this paper we use one…

Volunteering is often touted as a method to educate college students about social justice by providing students with an opportunity to apply classroom knowledge in a real-world setting. However, many critics have noted that service does not necessarily lead to social justice outcomes and that some forms of service may reinforce students'…

The aim of this study was to examine the concept development of decimal numbers in 244 Chinese elementary students in grades 4-6. Three grades of students differed in their intuitive sense of decimals and conceptual understanding of decimals, with more strategic approaches used by older students. Misconceptions regarding the density nature of…

Childhood obesity is a major public health problem associated with many adverse health outcomes in adulthood. During 2011-2012, nearly 17% of children and adolescents were obese. Weight status misperception occurs when the child's perception of their weight status differs from their actual weight status based on measured height and weight.…

The purpose of this study is to examine students' perceptions of the nature of science and metaphors related to the concept of robot, to determine the differentiation in these perceptions and metaphors resulting from LEGO NXT robot applications, and to share some good examples of education-oriented activities with robots. In this study, a hybrid…

The term "formative assessment" is often used to describe a type of assessment. The purpose of this paper is to challenge the use of this phrase given that "formative assessment" as a noun phrase ignores the well-established understanding that it is a process more than an object. A model that combines content, context, and strategies is presented…

Myths about immigration and immigrants are common. This article presents a few of the most frequently heard misconceptions, along with information to help teachers and their students separate fact from fear. Teachers should debunk the misinformation students bring to school--and help them think for themselves. They must guide students to find a…

There are a lot of misconceptions when it comes to community college. The general population appears to believe that because the tuition per credit hour is incredibly cheaper than that of the average university, students are receiving a "discounted," "cheap," "rip-off" education. Top community college students struggle against the mistaken…

Studies reveal that students as well as teachers have difficulties in understanding and learning of decimals. The purpose of this study is to investigate students' as well as pre-service teachers' solution strategies when solving a question that involves an estimation task for the value of a decimal number on the number line. We also examined the…

Students' inaccurate ideas about what is represented by chemical equations and concepts underlying stoichiometry are well documented; however, there are few classroom-ready instructional solutions to help students build scientifically accurate ideas about these topics central to learning chemistry. An intervention (two inquiry-based activities)…

Background/Context: High school educational environments find Black males experience systemic racial microaggressions in the form of discipline policies, academic tracking and hegemonic curriculum (Allen, Scott, & Lewis, 2013). Black males in high school are more likely than their White male peers to have high school truancies and be viewed as…

The authors mainly aimed to investigate the following question: Are there any significant effects of the first combined method of a conceptual change approach with refutation text, worksheets, and activities with respect to the second combined method of a conceptual change approach with conceptual texts, presentations, and activities on students'…

Policymakers and educators emphasize science, technology, engineering, and mathematics (STEM) instruction as key to individuals' and nations' future economic prosperity. It can be considered to be of particular value to students in developing countries and for disadvantaged students in developed countries. As families play a critical role in a…

Modern biology has become increasingly molecular in nature, requiring students to understand basic chemical concepts. Studies show, however, that many students fail to grasp ideas about atom rearrangement and conservation during chemical reactions or the application of these ideas to biological systems. To help provide students with a better…
