There is an inverse proportionality interlink between home language instruction and intellectual or cognitive development in the foundation phase

of education. This means that as the level of home language instruction increases, the level of intellectual and cognitive development in the foundation phase also decreases.

This is because home language instruction typically focuses on basic language skills and may not provide the same level of cognitive stimulation as more formal educational settings. As a result, children may not be exposed to as many opportunities for critical thinking, problem-solving, and other cognitive skills development.

On the other hand, formal educational settings often provide a more structured and comprehensive approach to intellectual and cognitive development. This includes opportunities for children to engage in activities that promote critical thinking, problem-solving, and other important cognitive skills.

Overall, while home language instruction is important for developing language skills, children may benefit from a combination of home language instruction and formal educational settings to support their intellectual and cognitive development in the foundation phase of education.
