The recent missions to Mars have produced a mass of data and information in all forms and have forced the minds of many people world-wide to rethink their own perspectives on life itself. This drama unfolding about 35 million miles from Earth, and digitally on our TV screens, is offering a growing reservoir for teachable moments. The curiosity and…

In this article, the authors report the results of a preliminary study of preservice teachers' ability to transfer their knowledge between their chemistry and Earth science courses. They examined whether they could answer the transfer questions correctly, how they explained their answers, and what information from their coursework they used to…

The National Assessment of Educational Progress (NAEP) and its reports are a key measure in informing the nation on how well the goal of scientific literacy for all students is being met. The "Science Framework for the 2015 National Assessment of Educational Progress" sets forth the design of the NAEP Science Assessment. This document is…

The world's population is growing by about 80 million people a year, implying an estimated increased freshwater demand of about 64 billion cubic meters annually (World Water Assessment Programme, 2009, Water in a Changing World: United Nations World Water Development Report 3, Chap. 1, p. 3-21). Groundwater depletion, which reduces the amount of…

An analysis of physical geology textbooks used in introductory courses shows that there is a systematic lack of clarity regarding flood risk. Some problems originate from confusion relating to statistical terms such as "100-year flood" and "100-year floodplain." However, the main problem is conceptual: statistics such as return…

Continental margins are an important part of the ocean floor. They separate the land above sea level from the deep ocean basins below and occupy about 11% of Earth's surface. They are also economically important, as they harbor both mineral resources and some of the most valuable fisheries in the world. In this article students investigate North…

Chronically high rates of new and experienced science teacher attrition and the findings of new large-scale mentoring programs indicate that administrators should adopt new approaches. A science teacher's role encompasses demanding responsibilities, such as observing laboratory safety and OSHA mandates, as well as management of a business-like,…

Real science means wrangling with peers over real ideas. Wouldn't it be thrilling to emulate a real life model of science in action in classrooms? How? By starting with a great, hands-on activity modeling an object in space that introduces both key vocabulary and science concepts with visuals to support retention and learning; encouraging…

The processes of developing and the results of testing a master's degree program designed to increase the number and quality of secondary-level earth science teachers are described in this paper. The master's program is intended to serve practicing secondary-level science and math teachers who lack subject-area endorsement in earth science. There…

Boy Scout geoscience education is not "desk" education--it is an informal, hands-on, real-world education where Scouts learn through activities, trips, and the outdoors, as well as in meetings and in the merit badge program. Merit badge requirements, many of which meet National Science Education Standards for Earth and Space Science,…

The Trends in International Mathematics and Science Study (TIMSS) is a comparative assessment of the achievement of students in many countries. In the present study, a rigorous independent evaluation was conducted of a representative sample of TIMSS science test items because item quality influences the validity of the scores used to inform…

The website "Earthlearningidea" was developed for the International Year of Planet Earth in 2007 and continues with one new activity per fortnight. Activities are devised to catch the attention of students and to enable them to enjoy the science of the Earth. Many activities require minimal equipment, for schools in developing countries, but there…

Eight Earth science graduate teaching assistants (GTAs) participated in a semester-long seminar designed to facilitate change in their practice. The seminar used lesson-study methodology to facilitate discussion of GTAs' beliefs about teaching while planning a research lesson for implementation in their laboratory. This article reports the results…

The purpose of this study was to find how the teacher could help students formulate scientific hypotheses. Data came from two microteaching episodes in which two groups of pre-service secondary science teachers taught high school students as they were engaged in abductive inquiry activities of earth science. Multiple data sources including video…

This study investigates critical thinking in a Physical Geography course and illustrates how students can understand physical geography in the context of their world. As a general education science course, most students are in non-science disciplines and feel disconnected from the material. By using exercises that challenge learning and concept…
