STORY:  Henry Fischel was the first person who invented the "EXAMS". Please forward to all students.. He has spoilt the fun of our life.

EFFECTIVE PEDAGOGY IN MATHEMATICS

1. An ethic of care                                              Caring classroom communities that are focused on mathematical goals help develop students’ mathematical identities and proficiencies .                                                                   Research findings                                    Teachers who truly care about their students work hard at developing trusting classroom communities. Equally importantly, they ensure that their classrooms have a strong mathematical focus and that they have high yet realistic expectations about what their students can achieve. In such a climate, students find they are able to think, reason, communicate, reflect upon, and critique the mathematics they encounter; their classroom relationships become a resource for developing their mathematical competencies and identities.  Caring about the development of students’ mathematical proficiency                                     Students want to learn in a harmonious env

SET & FUNCTIONS

Set function In mathematics, a  set function  is a function whose input is a  set . The output is usually a number. Often the input is a set of  real numbers , a set of points in  Euclidean space , or a set of points in some  measure space . Examples Examples of set functions include: The function that assigns to each set its  cardinality , i.e. the number of members of the set, is a set function. The function {\displaystyle d(A)=\lim _{n\to \infty }{\frac {|A\cap \{1,\dots ,n\}|}{n}},} Definition A set is a well-defined collection of distinct objects. The objects that make up a set (also known as the  elements  or members of a set) can be anything: numbers, people, letters of the alphabet, other sets, and so on. Membership If  B  is a set and  x  is one of the objects of  B , this is denoted  x  ∈  B , and is read as "x belongs to B", or "x is an element of B". If  y  is not a member of  B  then this is written as  y  ∉  B , and i
