Homeschooling involves parents choosing to educate their children at home instead of sending them to traditional public or private schools. The homeschooling movement grew in the 1970s when authors suggested it as an alternative. Currently, around 2.3 million students in the US are homeschooled, making up about 3% of school-aged children. Homeschooling allows for personalized education and strengthening family bonds but it also requires significant parental time and resources and can limit social interaction.
