Instructional Materials and Implementation of Next Generation Science Standards: Demand, Supply, and Strategic Opportunities

Next Generation Science Standards (NGSS) are in demand, but the supply of high quality K-12 instructional materials in science is lacking. This disconnect comes at a critical time in the implementation of new science standards, which are now influencing the teaching and learning of more than 50 percent of the students in American schools.  As of spring 2017, 18 states plus the District of Columbia have adopted the NGSS, and 16 states have adapted their state science standards based on the Framework for K-12 Science Education and the NGSS. As part of Carnegie Corporation of New York's Education Program, we have observed the growing need to improve the supply and demand for high quality K-12 instructional materials and professional learning designed for the NGSS. To inform the grantmaking in our Leadership and Teaching to Advance Learning portfolio, the Corporation recently held a convening of science curriculum developers, experts in professional learning, state and district science leaders, and other educators to discuss these challenges

The Hospitality Industry\u27s lmpact On the State of Nevada: A Summary & Review

This article summarizes the economic, fiscal, and social impact findings of The Hospitality Industry\u27s Impact on the State of Nevada, a report issued in November1998 by the International Gaming Institute. This summary includes data on jobs, wages, output, taxes, crime, and other social issues. A brief discussion is included regarding the authors\u27 opinions of the state\u27s dependence on the hospitality industry and gaming taxes, as well as the potential ramifications of this dependence in a changing economic environment

The Impact of Exercise in Spaceflight and Microgravity Environments

Since mankind’s first spaceflight, a significant barricade in reaching distant planets has been the damaging effects of microgravity upon the human body. Effects range from loss in bone mineral density and severe muscle atrophy to autoimmune disorders. The most effective countermeasure of these effects to date is exercise. Implementation of exercise in microgravity is not an easy task, so various specialized equipment must be utilized to effectively administer it. Even with this equipment, exercise as it is currently used does not entirely prevent body systems from undergoing detrimental changes. New modalities and implementations are currently being investigated that may significantly improve the ability of exercise to prevent major losses during long-distance spaceflight and allow for space agencies to put humans on another planet within the next few decades
