Teachers are highly reliant on textbooks for teaching. In the Republic of Korea, science textbooks help students to understand scientific terms through inquiry activities. However, there is a lack of analysis on whether the inquiry activities suggested in these textbooks appropriately cover the terms included in the main text. Therefore, this…

Typical assessment systems often measure isolated ideas rather than the coherent understanding valued in current science classrooms. Such assessments may motivate students to memorize, rather than to use new ideas to solve complex problems. To meet the requirements of the Next Generation Science Standards, instruction needs to emphasize sustained…

Using the life sciences, this article first reviews essential features of the "NRC Framework for K-12 Science Education" that provided a foundation for the new standards. Second, the article describes the important features of life science standards for elementary, middle, and high school levels. Special attention is paid to the teaching…

We use a construct-based assessment approach to measure learning progression of energy concepts across physical, life, and earth science contexts in middle school grades. We model the knowledge integration construct in six levels in terms of the numbers of ideas and links used in student-generated explanations. For this study, we selected 10 items…

This publication presents the Nebraska Science Standards for Grades K-12. The standards are presented according to the following grades: (1) Grades K-2; (2) Grades 3-5; (3) Grades 6-8; and (4) Grades 9-12.

Advocates that science teachers move from an emphasis on the discipline of science to one of helping learners see the short-, intermediate-, and long-term effects of their actions in regard to energy. Science teachers must, in the authors' opinions, go far beyond the traditional limits of science teaching. (PEB)

Described are a method of cultivating Euglena, a method for presenting and solving mole equations, and a design of a simple solar collector. (SL)

This document provides a review of the nine-week, secondary or college level Biological Sciences Curriculum Study (BSCS) unit entitled "Energy and Society: Investigations in Decision Making." Included is a reprint of the unit's last chapter which presents possible scenarios for future investigations and a report of evaluations made of…

Discusses the energy processes required to sustain life. Diffusion, oxygen transport, oxygen in arterial blood, and carbon dioxide transfer are the topical subdivisions discussed. (SA)

Reported are the differences in the understanding of concepts involved in photosynthesis and its role in ecology between students who had studied advanced biology and those who had not. Reports that the less experienced students had a poorer understanding of autotrophic respiration and energy aspects of photosynthesis. (CW)

Describes an underwater expedition which will allow students to participate in activities without being physically present. Provides a list of participating museums and examples of activities from curriculum materials which include a poster, bathymetric map, and 25 lessons. (RT)

The Louisiana coastal zone is a unique geographic feature. Soil carried by the Mississippi River has been deposited in Louisiana for the last 6,000 years to form the coastal area. All natural features in coastal Louisiana relate to materials and processes associated with the emptying of the Mississippi River into the Gulf of Mexico. The…

Fossil fuels, upon which we now depend almost exclusively, are finite resources. Because the environmental problems inherent in large scale fossil fuel consumption are increasingly apparent, the reality of developing alternative energy sources must be faced. Solar energy is the obvious solution to the problem. It is a renewable, clean source that…
