Researchers have found that the most effective way to raise a child's level of moral reasoning is to

A) praise the child's current level of thinking.
B) let the child develop without organized intervention.
C) present examples of moral reasoning that are slightly above the child's current level of functioning.
D) encourage the child to read accounts of famous historical figures known for their high moral standards.

Presenting examples of moral reasoning that are slightly above the child's current level of functioning has been found to be the most effective way to raise a child's level of moral reasoning. This approach challenges the child's current level of thinking without being too overwhelming, which leads to cognitive growth and improvement in moral reasoning. Praising the child's current level of thinking may reinforce their current level of moral reasoning, while letting the child develop without intervention may not provide the necessary exposure to diverse moral perspectives. Encouraging the child to read accounts of famous historical figures known for their high moral standards may also be beneficial but may not be as effective as presenting immediate examples that the child can relate to.
