Final answer:
Mr. Palinco is following Piaget's educational principle of cognitive development, utilizing the concept of schemata and the processes of assimilation and accommodation to support his students' learning.
Step-by-step explanation:
Mr. Palinco is adhering to the educational principle of cognitive development as theorized by Jean Piaget. Piaget's theory emphasizes the importance of schemata—mental models children use to categorize and interpret information—in learning. These schemata are adjusted through two key processes: assimilation (integrating new information within existing schemata) and accommodation (modifying schemata in response to new experiences). By presenting learning activities that build on his students' current thinking, yet also challenge their misconceptions, Palinco is encouraging cognitive growth through assimilation and accommodation. Furthermore, by recognizing when children are ready and interested in new skills, he is respecting the stages of cognitive development described by Piaget, ensuring that new concepts are introduced in line with the children’s developmental readiness.
