The National Research Council framework for science education and the Next Generation Science Standards have developed a need for additional research and development of curricula that is both technologically model-based and includes engineering practices. This is especially the case for biology education. This paper describes a quasi-experimental…

Modern biology has become increasingly molecular in nature, requiring students to understand basic chemical concepts. Studies show, however, that many students fail to grasp ideas about atom rearrangement and conservation during chemical reactions or the application of these ideas to biological systems. To help provide students with a better…

Advances in technology have caused high schools to update their computer science curricula; however there has been little analogous attention to technology-related education in middle schools. With respect to computer-related knowledge and skills, middle school students are at a critical phase in life, exploring individualized education options…

This document provides the framework to guide the development of the assessment instruments for the 2010 National Assessment of Educational Progress (NAEP) in geography. Altogether, four documents will be designed to guide the geography assessment and this Assessment Framework is the first. This framework is designed to assess the outcomes of…

This paper reports the findings of a survey conducted to investigate students' knowledge of geography, such as an accurate understanding of the basic vocabulary and essential concepts associated with the representative geographic locations, described here as "spatial landmarks". The factors that influence their learning, and how their…

For many, the dominant model of curriculum development in science includes generating a topic, clarifying science content, identifying activities associated with the topic, and figuring out an assessment. Unfortunately, this approach tends to overemphasize activities and underemphasize mastery of science concepts and the process of scientific…
