Teaching involves imparting knowledge and skills through activities that educate and instruct others. It can be carried out with or without a teacher and involves an agent providing learning, a goal to be achieved, and instructional methods. Teaching facilitates learning through interaction between teacher and students and organizes the acquisition of desirable information and development of knowledge in a dynamic, progressive, and diagnostic manner. While teaching aims to produce quantifiable results, it also focuses on developing students' critical thinking and meeting their diverse needs, making it both a process and product.
