Review by Eleanor J. Bader
Over the next 25 years, 5 billion kids worldwide will enroll in primary and secondary schools. These kids will need an education that meets 21st-century challenges, but most programs, Blumenthal and Pianta write, rely on a one-size-fits-all model that assumes that every child can learn the same material in the same top-down way. It isn’t true. “Learning should invite discovery, exploration, and risk-taking,” they write, and should be “personal, relational, and active.”
Retention suffers when this doesn’t happen. According to research and interviews conducted by the authors in more than 70 countries, when a student is academically disinterested, “one-third of the info presented to them is lost within 15 to 20 minutes; half is lost within the first hour, and three-quarters is lost within a day.” After a month, four-fifths is gone. Students may pass a test — hell, they may even get an A — but unless the coursework taps into their curiosity and allows them to investigate, probe, and connect with others, their engagement will likely be stifled and temporary.
But change is possible: Since today’s students are the first generation to be globally connected, Blumenthal and Pianta see endless potential for cross-cultural collaboration, with children, teens, and young adults working together to pursue scientific discoveries and find solutions to poverty, hunger, environmental calamity, and other pressing social issues. It’s an optimistic, if perhaps pie-in-the-sky, assessment.
The book does not tackle political repression, the massive influence of AI, the school privatization movement, or the necessity of teacher buy-in; nonetheless, Kids on Earth is a provocative conversation starter, relevant for everyone who wants to help kids develop the foundational skills they’ll need — including reading, writing, and basic arithmetic — to kickstart their creativity and stoke their passions.
As a roadmap for lifelong learning, the book serves as an antidote to staid scholarship. Provocative and likely to stir debate, the text asks important questions and offers bold suggestions for making education meaningful for future generations.
