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.

Abstract: The success of education and training depends on choosing appropriate problems and identifying the best solutions, and needs assessment is a tool that can achieve both. Discussion of the usefulness of needs assessment is followed by an outline of planning, the systems approach to planning, and how needs assessment relates to each. The 6 modes of needs assessment, and the relationship of inputs, processes, products, outputs, and outcomes to each type are presented. The application of these principles to school systems and curriculum development are then detailed. Two school case studies, consensual determining techniques, project and staff development, and noneducational contexts are presented.

Computer Systems Architecture provides IT professionals and students with the necessary understanding of computer hardware. It addresses the ongoing issues related to computer hardware and discusses the solutions supplied by the industry. The book describes trends in computing solutions that led to the current available infrastructures, tracing the initial need for computers to recent concepts such as the Internet of Things. It covers computers’ data representation, explains how computer architecture and its underlying meaning changed over the years, and examines the implementations and performance enhancements of the central processing unit (CPU). It then discusses the organization, hierarchy, and performance considerations of computer memory as applied by the operating system and illustrates how cache memory significantly improves performance. The author proceeds to explore the bus system, algorithms for ensuring data integrity, input and output (I/O) components, methods for performing I/O, various aspects relevant to software engineering, and nonvolatile storage devices, such as hard drives and technologies for enhancing performance and reliability. He also describes virtualization and cloud computing and the emergence of software-based systems’ architectures. Accessible to software engineers and developers as well as students in IT disciplines, this book enhances readers’ understanding of the hardware infrastructure used in software engineering projects. It enables readers to better optimize system usage by focusing on the principles used in hardware systems design and the methods for enhancing performance.

In the age of the Internet of Things and social media platforms, huge amounts of digital data are generated by and collected from many sources, including sensors, mobile devices, wearable trackers and security cameras. These data, commonly referred to as big data, are challenging current storage, processing and analysis capabilities. New models, languages, systems and algorithms continue to be developed to effectively collect, store, analyze and learn from big data.Programming Big Data Applications introduces and discusses models, programming frameworks and algorithms to process and analyze large amounts of data. In particular, the book provides an in-depth description of the properties and mechanisms of the main programming paradigms for big data analysis, including MapReduce, workflow, BSP, message passing, and SQL-like. Through programming examples it also describes the most used frameworks for big data analysis like Hadoop, Spark, MPI, Hive and Storm. Each of the different systems is discussed and compared, highlighting their main features, their diffusion (both within their community of developers and among users), and their main advantages and disadvantages in implementing big data analysis applications.

In most IT system development processes, the identification or elicitation of user requirements is recognized as a key building block. In practice, the identification of user needs and wants is a challenge and inadequate or faulty identifications in this step of an IT system development can cause huge problems with the final product. The elicitation of user requirements as such changes according to age groups;, to gender,; to cultural settings,; and into time; and experience in the use of the system/software. User requirements, therefore, cannot be used between projects, IT systems, and different software. That makes the elicitation of user requirements an inherent part of any software development project and a resourceful activity as well. This book provides insights to the process of identifying user requirements and to different types by describing varying case studies in which technologies or software has been developed. A variety of user requirements are provided illustrating the effect of changing the targeted user group with respect to age,; to the context and the different technologies or software as well as to the difference in viewpoint on ways of involving users in the elicitation process. Cases and user requirement elements discussed in the book include: User requirements elicitation processes for children, construction workers, and farmersUser requirements for personalized services of a broadcast companyVariations in user involvementPractical elements of user involvement and requirements elicitationUsable security requirements for design of privacy

In order to tackle the computer challenge, we will need an algorithm. A collection of instructions that must be carried out in order to transform an input into an outcome is referred to as an algorithm. One illustration of this would be the development of an algorithm to produce a classification. Your ordered list is the result, and the input is a series of numerical values to be arranged. You might be interested in discovering the most effective algorithm, which either needs fewer instructions or less memory or both, and you might discover that there are numerous algorithms for the same work. On the other hand, we do not have an algorithm for certain tasks, such as determining what constitutes spam and what constitutes legitimate e-mail. We are aware of the nature of the entry, which is a simple typeface file contained within an email document. We are aware of the expected outcome, which is a yes/no answer signifying whether or not the communication should be considered spam. We are not familiar with the process of converting information to output. The definition of what constitutes spam shifts over time and differs from one individual to the next. Using statistics, we are able to compensate for our dearth of understanding. We are able to quickly collect thousands of example messages, some of which we are aware are spam and would like to "learn" more about how they are constructed. Therefore, we would like the computer (machine) to automatically determine the procedure that should be used for this work. There is no need for you to learn how to arrange numbers because we already have algorithms for that; however, there are many applications with example data that do not require an algorithm. Because of developments in computer technology, we are now able to store and analyze large quantities of data, as well as retrieve this data from geographically dispersed locations through the use of a computer network. Most data acquisition instruments today are computerized and capture accurate data.
