Thorndike's intelligence theory is used in modern education because it believes that intelligence is not a single element, but a combination of various mental powers. Using the principles of this theory, tleachers can teach students based on different powers and skills and teach them according to their specific needs. It is used in modern education to identify the individual ability of the students and to train according to their weaknesses and strengths. Thorndike gives an idea that it is made up of three different elements: abstract, mechanical and social. This idea helps teachers to identify students' skills and interests, including abstract thoughts, mechanical work, and social relations. Based on this information, teachers can determine the appropriate teaching method for the students on the basis of interest and skills.
