Kohlberg’s Theory of Moral Development

Kohlberg’s theory of moral development is a stage-based model of moral maturity developed by Lawrence Kohlberg in 1958. The theory offers three levels of moral development, each of which contains two stages. Kohlberg asserts that moral development is neither the result of a genetic blueprint nor the result of conscious teaching of morality. Rather, it is a process of maturing that arises from thinking about moral issues. Read More

Lev Vygotsky’s theory of Socio Cultural Development

Vygotsky was called “The Mozart of Psychology“. He was born in 1896- same year as Piaget – in the small Russian town of Orsha.

The sociocultural theory:

  • Did NOT focus on the individual child but on the child as a product of social interaction, especially with adults (parents, teachers).
  • Focus on DYADIC INTERACTIONS (e.g., child being taught by a parent how to perform some culturally specific action), rather than child by himself.
  • Social world mediates children’s cognitive development. Cognitive development occurs as child’s thinking is molded by society in the form of parents, teachers, and peers. This leads to peer tutoring as a strategy in classrooms.
  • People’s thinking differs dramatically between cultures because different cultures stress different things.

Bloom’s Taxonomy of Educational Objectives

In 1956 Benjamin Bloom and some fellow researchers published a taxonomy of educational objectives that has been extremely influential in the research and practice of education ever since.

  • A taxonomy is a system of classification. Bloom and his colleagues categorized objectives from simple to complex, or from factual to conceptual.
  • These key elements are commonly known as Bloom’s taxonomy.

This taxonomy defines levels of objectives in 3 domains:

  1. Cognitive (knowledge based) – relating to intellectual capability i.e. knowledge or ‘think’
  2. Affective (emotive based) – relating to feelings, attitudes, values and behaviours
  3. Psychomotor (action based) – relating to physical coordination and performance of physical skills

CTET and State TET Maths – LCM and HCF Concepts

LCM stands for Lowest Common Multiple, and HCF stands for Highest Common Factor.

The key to telling the difference between these two things is knowing the difference between a multiple and a factor.

A multiple of an integer (whole number) is any integer that appears in its times table. For example, the multiples of 3 are 3, 6, 9, 12, and so on.

A factor of an integer is any integer that divides the integer with no remainder. For example, the factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.

We use LCM and HCF to compare two (or more) integers. Read More
