Many school teachers earn their supplementary income through tuition centers. Some teachers 'advertise' their tuition classes and coach those who attend their classes on how to tackle examination questions. Some teachers earn by giving private tuition and, because of this, perform less well at school.
Homeschooling or homeschool is the education of children at home, typically by parents but sometimes by tutors, rather than in other formal settings of public or private school. Although prior to the introduction of compulsory school attendance laws, most childhood education occurred within the family or community, homeschooling in the modern sense is an alternative in developed countries to formal education.
Homeschooling is a legal option in many places for parents to provide their children with a learning environment as an alternative to publicly-provided schools. Parents cite numerous reasons as motivations to homeschool, including better academic test results, poor public school environment, improved character/morality development, and objections to what is taught locally in public school. It may be a factor in the choice of parenting style. It is also an alternative for families living in isolated rural locations or living temporarily abroad.
Homeschooling may also refer to instruction in the home under the supervision of correspondence schools or umbrella schools. In some places, an approved curriculum is legally required if children are to be home-schooled.
A curriculum-free philosophy of homeschooling may be called unschooling, a term coined in 1977 by American educator John Holt in his magazine Growing Without Schooling.
