Meaning in statistics is fundamentally related to contexts, which poses the challenge to teach statistics in contexts, taking everyday reasoning as the basis from which to develop statistical reasoning. I investigate how 13 teachers-as-learners in an introductory statistics course co-structure their situation models toward a shared real model that…

This study examines the effect of physical activity on science instruction. To combat the implications of physical inactivity, schools need to be willing to consider all possible opportunities for students to engage in moderate-to-vigorous physical activity (MVPA). Integrating physical activity with traditional classroom content is one…

Whether you are someone new to the field of sex education, trying to start a library or resource center on adolescent sexual health, or an old pro, this guide should give you a basic orientation to what's available to support your work. These resources are important to advancing positive attitudes toward adolescent sexual health and the author…

This study reports the results of the first systematic investigation into Astro 101 students' conceptual and reasoning difficulties with cosmology. We developed four surveys with which we measured students' conceptual knowledge of the Big Bang, the expansion and evolution of the universe, and the evidence for dark matter. Our classical test theory…

To address the need for reform in undergraduate science education a new instructional model called "Argument-Driven Inquiry" (ADI) was developed and then implemented in a undergraduate chemistry course at a community college in the southeastern United States (Sampson, Walker, & Grooms, 2009; Walker, Sampson, & Zimmerman, in press). The ADI…

This research illustrates how varying enactments of an engineering-design-based science curriculum shaped the development of students' domain-specific scientific ideas and practices. In this comparative case study rooted in the analytical perspectives of activity theory and learning environments, student and teacher participants in three…

Using a sociocritical approach to the study of language and literacy and discourse analysis, this article examines student initiated challenges in a sheltered English course with two types of English learners: native+, ESL students; and, recently, arriving ESL students. The analysis draws on 19 hours of video-recorded observations of…

One goal of 21st-century education is to develop mature citizens who can identify issues, solve problems, and communicate solutions. What better way for students to learn these skills than by participating in a science and engineering fair? Fair participants face the same challenges as professional scientists and engineers, even Nobel laureates.…

Once an area of debate, there is now general consensus among media and social science researchers that online communities represent community in the traditional sense of the term, albeit with some important epistemological differences. If one considers online communities as genuine functioning communities situated in a legitimate cultural context,…

One critical element of increasing science literacy is student engagement. In this article, I report on the impacts of changing an introductory environmental science class to move away from standard lecture delivery and increase student engagement in science. The class was designed around small-group activities, inquiry labs, and substantial use…

North Dakota State University (USA) have been using video conferencing as a delivery mode for farmer education for about twenty years and report that their farmers find this delivery method both practical and worthwhile. With the number of New Zealand farmers attending learning events decreasing, due mainly to time and cost, maybe it is time to…

Say the phrase "Charlie bit my finger," and just about every human being with Internet access visualizes the viral video clip of baby Charlie precociously biting the finger of his brother. With almost 200 million views, this video represents just one of thousands of viral videos that form a core component of modern entertainment, news,…

Numerous educators have noted that Geographic Information Systems (GIS) is a powerful tool for social studies teaching and learning. Yet the use of GIS has been hampered by issues such as the cost of the software and the management of large spatial data files. One trend that shows great promise for GIS in education is the move to cloud computing.…

Research Findings: This study examined the extent to which maternal sensitivity in infancy and toddlerhood is associated with children's social and relational competence and problems in the early years of schooling as well as the extent to which this association is mediated by children's effortful control abilities. Data from 1,364 children (705…

Background/Context: The collegial analysis of student work artifacts has been effective in advancing the practice of experienced teachers; however, the use of such strategies as a centerpiece for induction has not been explored, nor has the development of tool systems to support such activity with novices. Purpose/Objective: We tested the…
