The Deliberate Dumbing Down of America by Charlotte Iserbyt (1999) presents a chronological history arguing that US education reformers have intentionally shifted focus from academic excellence to behavioral conditioning. It documents a, largely, 100-year plan to create a compliant workforce for a global economy through non-academic methodologies, rather than fostering independent thinking.
This book is essentially, largely, an exposé aiming to inform parents and educators about what the author considers a largely deliberate effort to degrade the largely American education system.
