The purpose of this study was to identify essential features of Epistemic Orientation toward Teaching Science (EOTS) and to explore the relationships between EOTS and instructional practices. This study proposes a new concept, EOTS: defined as a teacher's set of interrelated beliefs that are developed and used when teaching science, and are shaped…

Unfortunately, for the most part, teachers do not teach the Nature of Science (NOS). Even when teachers have adequate NOS knowledge, their knowledge still does not make its way into practice. While there are various reasons for this happening, this study has isolated other, more typical, constraints to teaching in order to look more closely at the…

Epistemic beliefs are individuals' beliefs about the nature of knowledge, how knowledge is constructed, and how knowledge can be justified.

In the past decade, there has been a growing interest in scientific practices as a reform focus in K-12 science education of the United States. In this context, scientific practices refer to practices that have family resemblance to scientists' professional practices and simultaneously are pedagogically accessible and useful to students. In…

This quantitative study examined the science-related attitudes of middle school girls who attended a science-focused mentoring program and those of middle school girls who attended a traditional mentoring program. Theories related to this study include social cognitive theory, cognitive development theory, and possible selves' theory. These…

The purpose of this study was to investigate the impact of gender and type of inquiry curriculum (open or structured) on science process skills and epistemological beliefs in science of sixth grade students. The current study took place in an urban northeastern middle school. The researcher utilized a sample of convenience comprised of 303 sixth…

This quantitative causal comparative study looked to see if there was a relationship between childhood obesity and student achievement. Because of the many conflicting results in the research available, it was not known if there was a relationship between childhood obesity and student achievement among inner-city middle school students in a school…

Historical thinking is an integral part of understanding and doing history, as well as a good example of the kind of critical thinking necessary in today's society.
