Drawing implications from Piaget's theory of cognitive development, a teacher of grade 6-8 in his classroom should

Grade 6-8 students (ages 11-14) are transitioning from the concrete operational stage to the formal operational stage in Piaget's theory. At this stage, they are developing the capacity for abstract and logical reasoning. Teachers should therefore present problems that require reasoning-based solutions to support and stimulate this developing cognitive ability. Discouraging logical arguments or relying solely on concrete materials would limit growth, and relying only on prescribed syllabus does not address cognitive development needs.
