Students do not have a good understanding of how rocks form. Instead, they have many non-scientific alternative conceptions to explain different aspects of rock formation. Using 10 interviews and nearly 200 questionnaires filled out by students at four different colleges, we identified many alternative conceptions students have about rock…

The goal of this study is to identify Thai students' prior knowledge about particle motion when P-waves arrive. This existing idea significantly influences what and how students learn in the classroom. The data were collected via conceptual open-ended questions designed by the researchers and through explanatory follow-up interviews. Participants…

The realm of Earth science (ES) is increasingly data-intensive. Geoinformatics research attempts to robustly smooth and accelerate the flow of data to information, information to knowledge, and knowledge to decisions and to supply necessary infrastructure and tools for advancing ES. Enabling easy access to and use of large volumes of ES data and…

The non-computational brand of cognitivism is based on the premise that performances, including those of children, are generated by mental models or representations, i.e., "internal" resources. The sociocultural approach, on the other hand, regards context, i.e., an "external" resource, as the chief means of elaborating…

Ed Willis Barnett had quite a military training: he attended the United States Naval Academy in Annapolis, Maryland, (1917 to 1920) and served in both World Wars. He was also an accomplished fencer, and earned a position on the 1928 U.S. Olympic fencing team. That year the summer Olympics were held in Amsterdam, so he traveled to Europe for the…

A systematic assessment of media-based coverage of geoscience topics relative to those found in textbooks is presented here. The specific question addressed is to what extent fully indexed media and print news sources can provide a useful model for course development. Whereas the improvement of students' scientific literacy cannot be achieved…

How does the brain learn to recognize an object from multiple viewpoints while scanning a scene with eye movements? How does the brain avoid the problem of erroneously classifying parts of different objects together? How are attention and eye movements intelligently coordinated to facilitate object learning? A neural model provides a unified…

Ethnic and racial minorities constitute an important part of the geosciences community because of their diverse perspectives and backgrounds. However, the geosciences have the poorest diversity record of all the science and engineering fields. Recruitment of minorities is important and numerous programs are focusing on engaging students in…

The Hudson River Watershed contains a variety of geologic, topographic, climatic, and hydrologic features and a diversity of land-use patterns--making it an ideal model for studying human impact on the coastal environment. In this article, the authors present the Hudson River Plume (HRP), a problem-based online module that explores nonpoint-source…

This study explored the phenomenon of testing effect during science concept assessments, including the mechanism behind it and its impact upon a learner's conceptual understanding. The participants consisted of 208 high school students, in either the 11th or 12th grade. Three types of tests (traditional multiple-choice test, correct concept test,…

Surveys of the earth science content of all secondary (high school) science textbooks and related publications used in England and Wales have revealed high levels of error/misconception. The 29 science textbooks or textbook series surveyed (51 texts in all) showed poor coverage of National Curriculum earth science and contained a mean level of one…

This study deals with the development of system thinking skills at the elementary school level. It addresses the question of whether elementary school students can deal with complex systems. The sample included 40 4th grade students from one school in a small town in Israel. The students studied an inquiry-based earth systems curriculum that…

When ice sheets melt, and reduce the load on the surface of the Earth, the land areas beneath them bounce back up. New, accurate observations are needed to investigate this uplift and its implications effectively. This article provides a topical starting point for investigating some applications of physics applied to the polar regions of the…

With the rapidly increasing entrance examinations for the School of Continuing education of CUGB, there is an urgent need of the examination papers that have the parallel testing ability for the same academic program. Based on the analysis of parallel factors and the comparison of the manual generated mode and the computer generated mode, the most…

Graduate teaching assistants (GTAs) teach many undergraduates in introductory science courses in the USA. Previous literature suggests that GTAs would prefer more context-dependent opportunities to learn to teach more effectively. This study explores the impact of participation in a lesson study cycle with GTAs responsible for an undergraduate…
