The document discusses the definition of discipline and causes of disciplinary problems in the classroom. Discipline stems from the word "disciple" meaning a follower of a teacher. Common causes of disciplinary issues include the teacher's inability to connect with and engage students, unmet social and physical needs of students, seeking attention, and parents not setting clear boundaries at home. From a teacher's perspective, disciplinary problems may arise due to boring teaching methods, teasing students, having no set rules, and home environment factors like abusive, lenient, or psychologically troubled upbringings.
