Plastic


Book Description

“This eloquent, elegant book thoughtfully plumbs the . . . consequences of our dependence on plastics” (The Boston Globe, A Best Nonfiction Book of 2011). From pacemakers to disposable bags, plastic built the modern world. But a century into our love affair, we’re starting to realize it’s not such a healthy relationship. As journalist Susan Freinkel points out in this eye-opening book, we’re at a crisis point. Plastics draw on dwindling fossil fuels, leach harmful chemicals, litter landscapes, and destroy marine life. We’re drowning in the stuff, and we need to start making some hard choices. Freinkel tells her story through eight familiar plastic objects: a comb, a chair, a Frisbee, an IV bag, a disposable lighter, a grocery bag, a soda bottle, and a credit card. With a blend of lively anecdotes and analysis, she sifts through scientific studies and economic data, reporting from China and across the United States to assess the real impact of plastic on our lives. Her conclusion is severe, but not without hope. Plastic points the way toward a new creative partnership with the material we love, hate, and can’t seem to live without. “When you write about something so ubiquitous as plastic, you must be prepared to write in several modes, and Freinkel rises to this task. . . . She manages to render the most dull chemical reaction into vigorous, breathless sentences.” —SF Gate “Freinkel’s smart, well-written analysis of this love-hate relationship is likely to make plastic lovers take pause, plastic haters reluctantly realize its value, and all of us understand the importance of individual action, political will, and technological innovation in weaning us off our addiction to synthetics.” —Publishers Weekly “A compulsively interesting story. Buy it (with cash).” —Bill McKibben, author of The End of Nature “What a great read—rigorous, smart, inspiring, and as seductive as plastic itself.” —Karim Rashid, designer

Making Sense of Test-Based Accountability in Education


Book Description

Test-based accountability systems that attach high stakes to standardized test results have raised a number of issues on educational assessment and accountability. Do these high-stakes tests measure student achievement accurately? How can policymakers and educators attach the right consequences to the results of these tests? And what kinds of tradeoffs do these testing policies introduce? This book responds to the growing emphasis on high-stakes testing and offers recommendations for more-effective test-based accountability systems.







Sweating the Small Stuff


Book Description

A Framework for K-12 Science Education


Book Description

Science, engineering, and technology permeate nearly every facet of modern life and hold the key to solving many of humanity's most pressing current and future challenges. The United States' position in the global economy is declining, in part because U.S. workers lack fundamental knowledge in these fields. To address the critical issues of U.S. competitiveness and to better prepare the workforce, A Framework for K-12 Science Education proposes a new approach to K-12 science education that will capture students' interest and provide them with the necessary foundational knowledge in the field. A Framework for K-12 Science Education outlines a broad set of expectations for students in science and engineering in grades K-12. These expectations will inform the development of new standards for K-12 science education and, subsequently, revisions to curriculum, instruction, assessment, and professional development for educators. This book identifies three dimensions that convey the core ideas and practices around which science and engineering education in these grades should be built. These three dimensions are: crosscutting concepts that unify the study of science through their common application across science and engineering; scientific and engineering practices; and disciplinary core ideas in the physical sciences, life sciences, and earth and space sciences and for engineering, technology, and the applications of science. The overarching goal is for all high school graduates to have sufficient knowledge of science and engineering to engage in public discussions on science-related issues, be careful consumers of scientific and technical information, and enter the careers of their choice. A Framework for K-12 Science Education is the first step in a process that can inform state-level decisions and achieve a research-grounded basis for improving science instruction and learning across the country. The book will guide standards developers, teachers, curriculum designers, assessment developers, state and district science administrators, and educators who teach science in informal environments.




Machine Scoring of Student Essays


Book Description

The current trend toward machine-scoring of student work, Ericsson and Haswell argue, has created an emerging issue with implications for higher education across the disciplines, but with particular importance for those in English departments and in administration. The academic community has been silent on the issue—some would say excluded from it—while the commercial entities who develop essay-scoring software have been very active. Machine Scoring of Student Essays is the first volume to seriously consider the educational mechanisms and consequences of this trend, and it offers important discussions from some of the leading scholars in writing assessment. Reading and evaluating student writing is a time-consuming process, yet it is a vital part of both student placement and coursework at post-secondary institutions. In recent years, commercial computer-evaluation programs have been developed to score student essays in both of these contexts. Two-year colleges have been especially drawn to these programs, but four-year institutions are moving to them as well, because of the cost-savings they promise. Unfortunately, to a large extent, the programs have been written, and institutions are installing them, without attention to their instructional validity or adequacy. Since the education software companies are moving so rapidly into what they perceive as a promising new market, a wider discussion of machine-scoring is vital if scholars hope to influence development and/or implementation of the programs being created. What is needed, then, is a critical resource to help teachers and administrators evaluate programs they might be considering, and to more fully envision the instructional consequences of adopting them. And this is the resource that Ericsson and Haswell are providing here.

Seeds of Change


Book Description

As a young girl in Kenya, Wangari was taught to respect nature. She grew up loving the land, plants, and animals that surrounded her--from the giant mugumo trees her people, the Kikuyu, revered to the tiny tadpoles that swam in the river. Although most Kenyan girls were not educated, Wangari, curious and hardworking, was allowed to go to school. There, her mind sprouted like a seed. She excelled at science and went on to study in the United States. After returning home, Wangari blazed a trail across Kenya, using her knowledge and compassion to promote the rights of her countrywomen and to help save the land, one tree at a time.
