Science presents many challenging topics, and incorrect prior knowledge of them often interferes with learning. Research has demonstrated that refutation texts promote conceptual change learning by helping readers abandon scientific misconceptions. Little is known about the factors that influence knowledge enrichment, the learning that ensues when…

Adoption of the Common Core State Standards present challenges to school districts, school administrators, and teachers. To assist in this endeavor, we present our work on unpacking the CCSS-M for the length, area, and volume Learning Trajectory (LT). The overarching theme of "genetic epistemology" and a five-characteristic framework…

While population mobility is a fundamental component of the lived experience of many Australian Aboriginal and Torres Strait Islander families, the ways in which educators and education systems respond (or fail to respond) to mobility demonstrates that there is very little understanding of this social and cultural phenomena. At the local school…

In view of the lack of instruments for measuring biology teachers' pedagogical content knowledge (PCK), this article reports on a study about the development of PCK items for measuring teachers' knowledge of pupils' errors and ways for dealing with them. This study investigated 9th and 10th grade German pupils' (n = 461) drawings in an achievement…

This study describes the development and validation of a three-tier multiple-choice diagnostic test, the atmosphere-related environmental problems diagnostic test (AREPDiT), to reveal common misconceptions of global warming (GW), greenhouse effect (GE), ozone layer depletion (OLD), and acid rain (AR). The development of a two-tier diagnostic test…

It's easy for overweight children to feel singled out and shamed about their body size, at home and at school. Experts say children can easily interpret even the well-intentioned "war on childhood obesity," meant to promote health, to mean a war on their bodies and on them. Size-based stigma stems in large part from the myth that being fat is a…

We present a diagnostic question cluster (DQC) that assesses undergraduates' thinking about photosynthesis. This assessment tool is not designed to identify individual misconceptions. Rather, it is focused on students' abilities to apply basic concepts about photosynthesis by reasoning with a coordinated set of practices based on a few scientific…

Medical students often have initial understanding concerning medical domains, such as the central cardiovascular system (CCVS), when they enter the study programme. These notions may to some extent be in conflict with scientific understanding, which can be seen as a challenge for medical teaching. Hence, the purpose of this study was to analyse…

Widely thought to be something worth encouraging in young learners, creativity has popularly been associated more with music and art than with other areas of the curriculum. There have been many studies of creativity but few that focus explicitly on what counts as creative thinking in specific subject areas. The aim of the research reported here…

The purpose of this qualitative study was to explore secondary science teachers' beliefs about multiculturalism and its implementation in their classrooms. Participants included nine secondary science teachers, with experience ranging from 1 to 15 years of teaching. Data were collected through interviews, using a semi-structured interview protocol…

The primary goal of education is to provide meaningful instruction to all students while fostering generalization throughout the curriculum and beyond. As such, educators continuously seek out instructional methods and techniques to appropriately meet individual student needs while choosing "what" and "how" to teach. The current work provides an…

Although it is possible to cite general trends about the concerns of beginning teachers, each beginner will have specific needs and questions. Clearly, mentoring matters, and mentors are especially helpful when they recognize and attend to the beginners' specific needs. Here, Erinn Bentley describes a "Wish List" she developed as a…

To capture students' excitement and engage their interest in rocketships and visiting planets in the solar system, the author designed lessons that give students the opportunity to experience the joys and challenges of developing straw rockets, and then observing which design can travel the longest distance. The lessons are appropriate for…

One-day professional development workshops for graduate students and postdocs were held at top National Research Council--ranked chemistry research departments. Attendees intend to pursue academic careers, yet their experience and knowledge about teaching and learning were small. Postsurveys indicated that despite the short duration, the workshop…

The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture…
