Education is a planned activity with certain goals in mind, such as knowledge transmission or the development of skills and character. These objectives might include the growth of comprehension, reason, kindness, and honesty. For the purpose of separating education from indoctrination, numerous studies emphasise the importance of critical thinking. The original purpose of education was to pass on cultural heritage to future generations. Today's educational objectives increasingly include novel concepts like learner liberation, modern social skills, empathy, and sophisticated vocational abilities. There are movements for education reforms, such as those for evidence-based educational approaches or enhancing the quality and effectiveness of education in order to make it more relevant to students' lives and effective at solving problems for the present or future society as a whole. Some states and the United Nations have acknowledged the right to an education.
