Final answer:
The statement is somewhat true as some but not all American schools have incorporated Howard Gardner's theory of multiple intelligences, which remains debated among cognitive psychologists but is favored by some for its inclusive approach.
Step-by-step explanation:
The statement that American schools have enthusiastically embraced Howard Gardner's theory of multiple intelligences to incorporate into curricula is true to a certain extent. While it is true that Gardner's theory of multiple intelligences, which identifies eight distinct forms of intelligence, has influenced some educators and institutions, the adoption is not universal. The theory has faced criticism from cognitive psychologists for a lack of empirical evidence. Still, it remains popular among some educators due to its inclusive approach that suggests all individuals can be smart in their own way, an appealing concept in democratic societies.
Despite the criticisms, the concept of multiple intelligences has been discussed and, in some cases, integrated into classroom settings, especially within some college environments. The attractiveness of Gardner's theory lies in its potential to foster a more personalized and diversified educational approach, sensitive to the varied talents and abilities of individual students. However, this does not imply that the theory is widely accepted or implemented across all American schools.
