Syllabus for Chemistry
According to the Curriculum Development Council, the broad aims of this chemistry curriculum are that students develop curiosity and interest in chemistry; acquire an appropriate body of knowledge and understanding in chemistry; acquire an ability to think rationally and critically, and to apply the knowledge of chemistry in making develop skills in scientific investigations; recognise the evolutionary and sometimes transitory nature of chemical knowledge; be acquainted with the language of chemistry and be equipped with the skills in communicating ideas in develop an appreciation of chemistry and its applications in daily life; become aware of the social, economic, environmental and technological implications of chemistry, and show concern for the environment and society; and develop open-mindedness, objectivity and proactiveness. VALUES AND ATTITUDES
The aims of the syllabus are to enable students to develop: awareness of the limitations of science; appreciation of the interrelationship or science, technology and society; appreciation of the role of scientific method in the development of new ideas; and TEXTBOOK

The cult of statistical significance

Section on Statistical Education – JSM 2009By Stephen T. Ziliak and Deirdre N. McCloskeyRoosevelt University and University of Illinois-Chicago Abstract: We want to persuade you of one claim: that William Sealy Gosset (1876-1937)—aka "Student" of "Student's" t-test—was right, and that his difficult friend, Ronald A. Fisher (1890-1962), though a genius, was wrong. Fit is no

Prednisone What is it?  Prednisone will decrease the inflammation in your kidneys so they can function Why did my doctor prescribe or recommend it?  Healthy kidneys filter out excess water, salts, and waste products from the blood in our body. They do this through many tiny filters that the blood flows through. You have a kidney disease because your immune system is damagi
