Learners’ Responses to the Demands of Conceptual Change: Considerations for Effective Nature of Science Instruction

Much has been written about how effective nature of science instruction must have a significant explicit and reflective character. However, while explicitly drawing students’ attention to NOS issues is crucial, learning and teaching the NOS are essentially matters of conceptual change. In this article, how people learn and learners’ responses to the demands of conceptual change are used to expl...

Research considerations for more effective groundwater monitoring.

Since numerous pathogens occur in feces, water is monitored for fecal contamination using indicator organisms rather than individual pathogens. Although this approach is supported by health effects data in recreational waters, it is questionable when used for drinking water. Most outbreaks in groundwater occur in systems that have not violated the US EPA's maximum contaminant limit (MCL) for to...

Considerations for effective rank based noise attenuation

Incoherent noise attenuation remains a challenging problem in seismic data processing. While many tools are successful at removing noise, this often comes at the expense of some signal. We seek the ideal noise attenuator– one that is effective, practical, and above all safe. Multichannel Singular Spectrum Analysis (MSSA) is a step in this direction. MSSA exploits the spatial redundancy of data ...

Statistical Methods for Communication Science

Clear messages for effective communication.

urgent, instant, up-to-the minute news and messages (think CNN, the Internet, BlackBerries, iPhones). Many statistics detail the costs of information overload to businesses. But what about the costs to the public? The average person receives hundreds—if not thousands—of bits of information every day. In 1997, a Reuters report stated that “In the last 30 years mankind has produced more informa­ ...
