Climate change encompasses a broad and complex set of concepts that is often challenging for students and educators. Using a learning progressions (LPs) knowledge system, we developed a LP that described student learning of climate change. In this exploratory study, we present findings from written assessments of climate change (n = 294) and…

We report a novel educational activity designed to teach quantum mechanical tunneling to upper-division undergraduate students in the context of nanochemistry. The activity is based on a theoretical framework for analogy and is split into three parts that are linked pedagogically through the framework: classical ball-and-ramp system, tunneling…

President Obama's 2009 speech in Prague is remembered as a call for the eventual elimination of nuclear weapons. It reinvigorated a long-overdue policy debate in the United States and Europe. Unfortunately, that debate is characterized by a focus on arsenal size that borders on numerology, a lack of imagination consistent with presentism, and…

This paper reports on an investigation into pre-service teachers' mathematical content knowledge and their ability to interpret students' responses to a multi-digit multiplication task and make subsequent appropriate teaching decisions. Using a combination of quantitative and qualitative methods, the researchers tested aspects of the mathematical…

This study explores the use of historical short stories as nature of science (NOS) instruction in thirteen secondary science classes. The stories focus on the development of science ideas and include statements and questions to draw students' and teachers' attention to key NOS ideas and misconceptions. This study used mixed methods to examine how…

This is a research study conducted on 17 teachers who teach English in Saudi international schools. It mainly aims at exploring teaching practices in these schools in terms of the principles of communicative language teaching (CLT). It also investigates the appropriateness of CLT in this context from the point of view of teachers. Two research…

School-based HIV/AIDS science education has the potential to impact students when integrated into the science curriculum. However, this mixed method study shows that school-based HIV/AIDS science education is often not infused into career subjects such as science education but integrated into civics education and taught by teachers who lack the…

Within middle school classrooms a diverse body of students require specialized instruction and science teachers with unique abilities to implement a reform-based science curriculum. To achieve the goal of success for all, students who are English language leaners and with exceptionalities, such as learning disabilities, and emotional and…

This study of advanced readers in Reading First (RF) classrooms was part of a larger evaluation of one state's RF implementation. The study's purposes were to (a) assess the longitudinal growth of advanced primary readers as compared with their non-advanced-reading peers over a 3-year timeframe and (b) determine the degree to which RF classrooms…
