Book excerpt: Advances in molecular biology and toxicology are paving the way for major improvements in the evaluation of the hazards posed by the large number of chemicals found at low levels in the environment. The National Research Council was asked by the U.S. Environmental Protection Agency to review the state of the science and create a far-reaching vision for the future of toxicity testing. The book finds that developing, improving, and validating new laboratory tools based on recent scientific advances could significantly improve our ability to understand the hazards and risks posed by chemicals. This new knowledge would lead to much more informed environmental regulations and dramatically reduce the need for animal testing because the new tests would be based on human cells and cell components. Substantial scientific efforts and resources will be required to leverage these new technologies to realize the vision, but the result will be a more efficient, informative and less costly system for assessing the hazards posed by industrial chemicals and pesticides.

Download or read book Assessment and Teaching of 21st Century Skills written by Patrick Griffin and published by Springer. This book was released on 2014-10-21 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second volume of papers from the ATC21STM project deals with the development of an assessment and teaching system of 21st century skills. Readers are guided through a detailed description of the methods used in this process. The first volume was published by Springer in 2012 (Griffin, P., McGaw, B. & Care, E., Eds., Assessment and Teaching of 21st Century Skills, Dordrecht: Springer). The major elements of this new volume are the identification and description of two 21st century skills that are amenable to teaching and learning: collaborative problem solving, and learning in digital networks. Features of the skills that need to be mirrored in their assessment are identified so that they can be reflected in assessment tasks. The tasks are formulated so that reporting of student performance can guide implementation in the classroom for use in teaching and learning. How simple tasks can act as platforms for development of 21st century skills is demonstrated, with the concurrent technical infrastructure required for its support. How countries with different languages and cultures participated and contributed to the development process is described. The psychometric qualities of the online tasks developed are reported, in the context of the robustness of the automated scoring processes. Finally, technical and educational issues to be resolved in global projects of this nature are outlined.

Available in PDF, EPUB and Kindle. Book excerpt: The routine jobs of yesterday are being replaced by technology and/or shipped off-shore. In their place, job categories that require knowledge management, abstract reasoning, and personal services seem to be growing. The modern workplace requires workers to have broad cognitive and affective skills. Often referred to as "21st century skills," these skills include being able to solve complex problems, to think critically about tasks, to effectively communicate with people from a variety of different cultures and using a variety of different techniques, to work in collaboration with others, to adapt to rapidly changing environments and conditions for performing tasks, to effectively manage one's work, and to acquire new skills and information on one's own. The National Research Council (NRC) has convened two prior workshops on the topic of 21st century skills. The first, held in 2007, was designed to examine research on the skills required for the 21st century workplace and the extent to which they are meaningfully different from earlier eras and require corresponding changes in educational experiences. The second workshop, held in 2009, was designed to explore demand for these types of skills, consider intersections between science education reform goals and 21st century skills, examine models of high-quality science instruction that may develop the skills, and consider science teacher readiness for 21st century skills. The third workshop was intended to delve more deeply into the topic of assessment. The goal for this workshop was to capitalize on the prior efforts and explore strategies for assessing the five skills identified earlier. The Committee on the Assessment of 21st Century Skills was asked to organize a workshop that reviewed the assessments and related research for each of the five skills identified at the previous workshops, with special attention to recent developments in technology-enabled assessment of critical thinking and problem-solving skills. In designing the workshop, the committee collapsed the five skills into three broad clusters as shown below: Cognitive skills: nonroutine problem solving, critical thinking, systems thinking Interpersonal skills: complex communication, social skills, team-work, cultural sensitivity, dealing with diversity Intrapersonal skills: self-management, time management, self-development, self-regulation, adaptability, executive functioning Assessing 21st Century Skills provides an integrated summary of the presentations and discussions from both parts of the third workshop.

Book excerpt: Signs of Change: Assessment Past, Present and Future Another Time, Another Place...Examinations Then and Now In the Temple of Literature in Hanoi, Vietnam, a series of stone stelae records the names of the handful of illustrious examination candidates who, in each century, passed the national examination to become a Doctor of Literature. Beginning in the 11thcentury,theexamswereconductedpersonallybysuccessivekingswhopursued Confucian ideals that found expression in the enormous value placed on the pursuit of wisdom and learning. In the 21st century we are both puzzled and impressed by this tradition. Puzzled by such an explicit commitment to a meritocracy in an essentially feudal society; impressed by this enthusiasm for learning and the pursuit of wisdom at the highest level of society. Yet, there are also important similarities between the 11th and 21st centuries. Then, as now, assessment was associated with excellence, high standards, pr- tige and competition—success for the chosen few; disappointment for the majority. Then, as now, the pursuit of excellence was embedded in a social context that favoured the elite and determined success in terms of the predilections of the p- erful. Then, as now, the purpose of the assessment, the way it was conducted and its impact on society all re ected the social and economic priorities of the day.

Download or read book Exposure Science in the 21st Century written by National Research Council and published by National Academies Press. This book was released on 2012-10-28 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the use of personal products to our consumption of food, water, and air, people are exposed to a wide array of agents each day-many with the potential to affect health. Exposure Science in the 21st Century: A Vision and A Strategy investigates the contact of humans or other organisms with those agents (that is, chemical, physical, and biologic stressors) and their fate in living systems. The concept of exposure science has been instrumental in helping us understand how stressors affect human and ecosystem health, and in efforts to prevent or reduce contact with harmful stressors. In this way exposure science has played an integral role in many areas of environmental health, and can help meet growing needs in environmental regulation, urban and ecosystem planning, and disaster management. Exposure Science in the 21st Century: A Vision and A Strategy explains that there are increasing demands for exposure science information, for example to meet needs for data on the thousands of chemicals introduced into the market each year, and to better understand the health effects of prolonged low-level exposure to stressors. Recent advances in tools and technologies-including sensor systems, analytic methods, molecular technologies, computational tools, and bioinformatics-have provided the potential for more accurate and comprehensive exposure science data than ever before. This report also provides a roadmap to take advantage of the technologic innovations and strategic collaborations to move exposure science into the future.

This book was released on 2017-03-16 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, several large-scale United States and international programs have been initiated to incorporate advances in molecular and cellular biology, -omics technologies, analytical methods, bioinformatics, and computational tools and methods into the field of toxicology. Similar efforts are being pursued in the field of exposure science with the goals of obtaining more accurate and complete exposure data on individuals and populations for thousands of chemicals over the lifespan; predicting exposures from use data and chemical-property information; and translating exposures between test systems and humans. Using 21st Century Science to Improve Risk-Related Evaluations makes recommendations for integrating new scientific approaches into risk-based evaluations. This study considers the scientific advances that have occurred following the publication of the NRC reports Toxicity Testing in the 21st Century: A Vision and a Strategy and Exposure Science in the 21st Century: A Vision and a Strategy. Given the various ongoing lines of investigation and new data streams that have emerged, this publication proposes how best to integrate and use the emerging results in evaluating chemical risk. Using 21st Century Science to Improve Risk-Related Evaluations considers whether a new paradigm is needed for data validation, how to integrate the divergent data streams, how uncertainty might need to be characterized, and how best to communicate the new approaches so that they are understandable to various stakeholders.

Available in PDF, EPUB and Kindle. Book excerpt: Americans have long recognized that investments in public education contribute to the common good, enhancing national prosperity and supporting stable families, neighborhoods, and communities. Education is even more critical today, in the face of economic, environmental, and social challenges. Today's children can meet future challenges if their schooling and informal learning activities prepare them for adult roles as citizens, employees, managers, parents, volunteers, and entrepreneurs. To achieve their full potential as adults, young people need to develop a range of skills and knowledge that facilitate mastery and application of English, mathematics, and other school subjects. At the same time, business and political leaders are increasingly asking schools to develop skills such as problem solving, critical thinking, communication, collaboration, and self-management - often referred to as "21st century skills." Education for Life and Work: Developing Transferable Knowledge and Skills in the 21st Century describes this important set of key skills that increase deeper learning, college and career readiness, student-centered learning, and higher order thinking. These labels include both cognitive and non-cognitive skills- such as critical thinking, problem solving, collaboration, effective communication, motivation, persistence, and learning to learn. 21st century skills also include creativity, innovation, and ethics that are important to later success and may be developed in formal or informal learning environments. This report also describes how these skills relate to each other and to more traditional academic skills and content in the key disciplines of reading, mathematics, and science. Education for Life and Work: Developing Transferable Knowledge and Skills in the 21st Century summarizes the findings of the research that investigates the importance of such skills to success in education, work, and other areas of adult responsibility and that demonstrates the importance of developing these skills in K-16 education. In this report, features related to learning these skills are identified, which include teacher professional development, curriculum, assessment, after-school and out-of-school programs, and informal learning centers such as exhibits and museums.

Download or read book Toxicity Testing for Assessment of Environmental Agents written by National Research Council and published by National Academies Press. This book was released on 2006-04-07 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxicity testing in laboratory animals provides much of the information used by the Environmental Protection Agency (EPA) to assess the hazards and risks associated with exposure to environmental agents that might harm public health or the environment. The data are used to establish maximum acceptable concentrations of environmental agents in drinking water, set permissible limits of exposure of workers, define labeling requirements, establish tolerances for pesticides residues on food, and set other kinds of limits on the basis of risk assessment. Because the number of regulations that require toxicity testing is growing, EPA called for a comprehensive review of established and emerging toxicity-testing methods and strategies. This interim report reviews current toxicity-testing methods and strategies and near-term improvements in toxicity-testing approaches proposed by EPA and others. It identifies several recurring themes and questions in the various reports reviewed. The final report will present a long-range vision and strategic plan to advance the practices of toxicity testing and human health assessment of environmental contaminants.

Available in PDF, EPUB and Kindle. Book excerpt: Performance assessment is a hot topic in school systems, and educators continue to analyze its costs, benefits, and feasibility as a replacement for high-stakes testing. Until now, researchers and policymakers have had to dig to find out what we know and what we still have to learn about performance assessment. Beyond the Bubble Test: How Performance Assessments Support 21st Century Learning synthesizes the latest findings in the field, and not a moment too soon. Statistics indicate that the United States is in danger of falling behind if it fails to adapt to our changing world. The memory and recall strategies of traditional testing are no longer adequate to equip our students with the skills they need to excel in the global economy. Instead teachers need to engage students in deeper learning, assessing their ability to use higher-order skills. Skills like synthesizing information, understanding evidence, and critical problem-solving are not achieved when we teach to multiple-choice exams. Examples in Beyond the Bubble Test paint a useful picture of how schools can begin to supplement traditional tests with something that works better. This book provides new perspectives on current performance assessment research, plus an incisive look at what’s possible at the local and state levels. Linda Darling-Hammond, with a team of leading scholars, bring together lessons learned, new directions, and solid recommendations into a single, readily accessible compendium. Beyond the Bubble Test situates the current debate on performance assessment within the context of testing in the United States. This comprehensive resource also looks beyond our U.S. borders to Singapore, Hong Kong, and other places whose reform-mindedness can serve as an example to us.

Download or read book Exploring the Intersection of Science Education and 21st Century Skills written by National Research Council and published by National Academies Press. This book was released on 2010-01-26 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: An emerging body of research suggests that a set of broad "21st century skills"-such as adaptability, complex communication skills, and the ability to solve non-routine problems-are valuable across a wide range of jobs in the national economy. However, the role of K-12 education in helping students learn these skills is a subject of current debate. Some business and education groups have advocated infusing 21st century skills into the school curriculum, and several states have launched such efforts. Other observers argue that focusing on skills detracts attention from learning of important content knowledge. To explore these issues, the National Research Council conducted a workshop, summarized in this volume, on science education as a context for development of 21st century skills. Science is seen as a promising context because it is not only a body of accepted knowledge, but also involves processes that lead to this knowledge. Engaging students in scientific processes-including talk and argument, modeling and representation, and learning from investigations-builds science proficiency. At the same time, this engagement may develop 21st century skills. Exploring the Intersection of Science Education and 21st Century Skills addresses key questions about the overlap between 21st century skills and scientific content and knowledge; explores promising models or approaches for teaching these abilities; and reviews the evidence about the transferability of these skills to real workplace applications.

Download or read book College Admissions for the 21st Century written by Robert J. Sternberg and published by Harvard University Press. This book was released on 2011-02-01 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: SATs, ACTs, GPAs. Everyone knows that these scores can’t tell a college everything that’s important about an applicant. But what else should admissions officers look for, and how can they know it when they see it? In College Admissions for the 21st Century a leading researcher on intelligence and creativity offers a bold and practical approach to college admissions testing. Standardized tests are measures of memory and analytical skills. But the ever-changing global society beyond a college campus needs more than just those qualities, argues Robert Sternberg. Tomorrow’s leaders and citizens also need creativity, practicality, and wisdom. How can the potential for those complex qualities be measured? One answer is “Kaleidoscope,” a new initiative in undergraduate admissions, first used at Tufts University. Its open-ended questions for applicants, and the means used to score the answers, gives applicants and admissions officers the chance to go beyond standardized tests. Does it work? As Sternberg describes in detail, Kaleidoscope measures predicted first-year academic success, over and above SATs and high school GPAs, and predicted first-year extracurricular activities, leadership, and active citizenship as well. And every year that Kaleidoscope measures were used, the entering class’s average SATs and high school GPAs went up too. What worked at Tufts can work elsewhere. New kinds of assessments, like Kaleidoscope, can liberate many colleges and students from the narrowness of standardized tests and inspire new approaches to teaching for new kinds of talented, motivated citizens of the world.
