...24 Chapter 132 - Science and Technology Section SCIENCE AND TECHNOLOGY Science and technology provide people with the knowledge and tools to understand and address many of the challenges. Students must be provided with opportunities to access, understand, and evaluate current information and tools related to science and technology if they are to be ready to live in a 21st century global society. The study of science and technology includes both processes and bodies of knowledge. Scientific processes are the ways scientists investigate and communicate about the natural world. The scientific body of knowledge includes concepts, principles, facts, laws, and theories about the way the world around us works. Technology includes the technological design process and the body of knowledge related to the study of tools and the effect of technology on society. Science and technology merge in the pursuit of knowledge and solutions to problems that require the application of scientific understanding and product design. Solving technological problems demands scientific knowledge while modern technologies make it possible to discover new scientific knowledge. In a world shaped by science and technology, it is important for students to learn how science and technology connect with the demands of society and the knowledge of all content areas. It is equally important that students are provided with learning experiences that integrate tools, knowledge, and processes of science and...

They are now also more able to make intelligent decisions as members of their societies when it comes to social issues and problems. So it is a very big problem when the members of the educational system itself are the ones experiencing difficulties in doing their duties. One of the more obvious areas that has suffered greatly is in the field of Science.

The Advancement Book Critique

...attitude of staleness, rather than revolving and advancing. Bush’s book (2003) is divided into eight chapters. It starts with Chapter 1, entitled “The Worldview of the Advancement”. This chapter discusses the fundamental of compare and contrast of modern view and earlier view of God, nature, history and mankind. The second chapter of Bush’s book, The Rise in the Advancement of Science, pays particular attention the development of modern science. The rise of uniformitarian thought in evolution. “The human body is related to nature, and it is similar in many respects to the body of animals” (34). This thought does not include that the Christian view that a human body is different than animals. We have a soul, whereas, animals do not. Sigmund Freud’s The Future of an Illusion, argued that religion base on wishful illusion, rather than reality. Bush’s third chapter (2003), The Advancement and the Theory of Knowledge, concentrate on how science effects and outcomes with the absence of God. The Bible promotes the idea that man was made in the image of God. However naturalistic biological evolution “explains the variety of living things as being a set of natural variations of organic matter. Every life-form, including human life, supposedly arose from the same underlying reality” (page 38). The only reality that exist is physical reality. Bush refers to this as “nature”.
