Exploring alternative methods for early education in Chicago Heights: Economists Dubner, List, and Levitt set up an experimental preschool to test effective teaching methods and expand beyond traditional classroom settings, aiming to make a difference in underprivileged communities.
Economists Stephen J. Dubner, John List, and Steve Levitt embarked on an experiment to improve early education in a relatively poor community in Chicago Heights. They set up an experimental preschool to test state-of-the-art techniques for teaching cognitive skills and non-cognitive skills, such as sitting still and expanding working memory. The overarching goal was to not only teach children but also to learn what methods are effective. However, the most intriguing aspect of their experiment was not limited to the school. They aimed to explore alternative methods and settings outside of the traditional classroom setting. List, who grew up in a public education system and saw firsthand the disparities between affluent and underprivileged students, was particularly motivated to make a difference. The trio's work demonstrates the importance of continuous learning and innovation in addressing educational challenges.
Impact of Education on Parents in Chicago Heights: The Chicago Heights experiment demonstrated the importance of involving parents in their children's education and the challenges of implementing innovative parent academy programs.
The impact of education goes beyond the classroom and extends to the home. The Chicago Heights experiment aimed to improve children's academic performance by equipping their parents with better teaching skills through a parent academy. The parents attended sessions every two weeks for 90 minutes over a nine-month period, and their attendance and children's progress were incentivized. The goal was to create better teachers for all siblings and not just the enrolled child. However, setting up the parent academy was a complex and costly endeavor, requiring the support of the superintendent, state licenses, community trust, funding for teachers, curriculum development, and incentives. The experiment cost nearly $1 million, which was funded by the Anne and Ken Griffin Foundation. The results were satisfactory, but not groundbreaking. The foundation eventually shut down due to unrelated circumstances, but the economists were able to use the funding to run the preschool and parent academy. This experiment highlights the importance of recognizing the role of parents in a child's education and the challenges of implementing innovative education initiatives.
Parent Academy shows gains for Hispanic and white students, but not for African-American families: The Parent Academy project, which taught parents how to engage with their preschoolers to boost cognitive and non-cognitive skills, had positive effects for Hispanic and white children, but not for African-American families. Researchers are now seeking explanations and potential solutions to this disparity.
The "Parent Academy" experimental project, which aimed to teach parents how to effectively engage with their preschoolers to improve cognitive and non-cognitive skills, showed significant gains for Hispanic and white students. However, the program did not yield similar results for African-American families, leaving researchers puzzled and in search of potential solutions. Despite this disparity, the Parent Academy proved effective in enhancing the development of some children in just nine months. The economists involved in the study are still analyzing the results of the preschool curriculum, but the Parent Academy's impact on parental involvement and children's cognitive and non-cognitive skills is clear.
The role of non-cognitive skills in academic success: Children with below-average non-cognitive skills made no progress, while those with above-average skills saw significant gains, emphasizing the importance of addressing non-cognitive skills early on, even before preschool.
That non-cognitive skills, such as the ability to concentrate and remember things, play a crucial role in a child's academic success. The Parent Academy research showed that kids who entered the program with below-average non-cognitive skills made no progress, regardless of their cognitive abilities. On the other hand, children with above-average non-cognitive skills saw significant gains. This finding highlights the importance of addressing non-cognitive skills early on, potentially even before a child enters preschool. The brain's development is heavily influenced by the experiences it encounters in the first few years of life, and language plays a significant role in building neural connections during this critical period. This research also suggests that schools may not have as much influence on a child's academic success as previously thought, and that efforts to improve educational outcomes should focus on what happens at home, particularly in the early years.
The Impact of Age and Socioeconomic Background on Language Development for Children with Hearing Loss: Younger age at implantation and a supportive socioeconomic background are crucial for optimal language development in children with hearing loss. Dr. Suskind's research highlights the significance of addressing both physiological and socioeconomic needs to ensure long-term success.
While advancements in technology, such as cochlear implants, have greatly improved the lives of children with hearing loss, simply providing them with the ability to hear is not enough for optimal language development. The age at which a child receives an implant and their socioeconomic background play significant roles in their language learning abilities. Dr. Suskind, a leading expert in this field, discovered this through her work with patients and their families. She found that children who receive implants at younger ages, before the age of three, have a much easier time learning language due to the brain's heightened neuroplasticity during this period. However, she also realized that many of her patients from low-income backgrounds faced additional challenges that extended beyond the operating room. In response, Dr. Suskind founded Project Aspire to support these children and later the 30 Million Words Initiative, which aims to raise awareness about the importance of early language development and the impact of socioeconomic factors on children's lives. Ultimately, Dr. Suskind's work underscores the importance of addressing both the physiological and socioeconomic needs of children with hearing loss to ensure their long-term success.
Word deficit in children from poverty backgrounds: Children from poverty backgrounds hear 30 million fewer words by age 3, causing delays in language processing and brain development. Programs like 30 Million Words Initiative teach parents effective communication skills to improve child's language environment.
Children from poverty backgrounds hear 30 million fewer words by the age of three compared to their peers from more affluent backgrounds. This word deficit, coupled with lower quality input, leads to significant delays in language processing and brain development. The quality of interaction, including the use of affirmations, complex vocabulary, and verbal back-and-forth, plays a crucial role. To address this issue, organizations like Suskind's 30 Million Words Initiative are developing evidence-based programs, such as home-visiting services, to teach parents effective communication skills during the critical years of brain development. The 30 Million Words home visiting program aims to improve parent-child interaction by explaining the science behind language development and providing ongoing support. The program, which is being run as a randomized controlled trial, has enrolled 200 families and will test its efficacy over several years. By focusing on improving the language environment, these initiatives aim to help build a stronger foundation for children's future learning and success.
TMW Initiative's Research on Children's Language Development: Children with slower word processing speeds due to less language exposure struggle to learn new words and fall behind in language development. Parents can prevent this by effectively communicating using the 'three T's': Tune in, Talk more, and Take turns.
The TMW Initiative is conducting research on children's language development, focusing on their word processing speed and communication environment. Sincere, a child in the study, averaged 963 words per hour during a recording session, falling short of a 1,100-word goal. The initiative also measures brain processing speed through eye movement analysis. Children exposed to less language have slower processing speeds, making it harder for them to learn new words and fall behind in language development. This deficit starts compounding at a young age, making prevention more important than remediation. The TMW program advocates for parents to communicate effectively with their children using the "three T's": Tune in (following a child's lead), Talk more (using rich vocabulary), and Take turns (viewing children as conversational partners).
The Three Ts: Tune in, Talk more, and Take turns: Effective communication and behavior skills are crucial for a child's success. Use 'The Three Ts' as a reminder to tune in to your child, talk more, and take turns to help them learn self-regulation and improve behavior.
Building a child's intelligence is not the only important factor for their success. Their behavior is equally crucial. The "Three Ts" - Tune in, Talk more, and Take turns - are essential foundational behaviors for interacting with children and should be used as a reminder that non-cognitive skills are just as valuable as cognitive ones. Parents in a study noticed that while they knew how to build their child's brain, they wanted to learn how to use language to help them behave better. Therefore, a week was added to explain children's executive function and prefrontal cortex development and how language and modeling can help improve their behavior. Children need to learn self-regulation, and observing adults using their red light (emotional control) to self-regulate in challenging situations is essential. While one vigilant parent may be better than two inconsistent ones, it's important to note that parent-child conversation is the highest form of language acquisition. However, screens, such as TV, are not as effective because they are not responsively contingent, meaning they do not respond to the child's cues. Interaction with a responsively contingent adult, like through Skype, can help children learn vocabulary. Ultimately, building a strong foundation for a child's future success involves both cognitive and behavioral development.
The Role of Educational TV in Early Learning: A Rigorous Analysis using Sesame Street as an Example: Economists Melissa Carney and Phil Levine used a rigorous analysis to prove the positive impact of Sesame Street on early learning by comparing academic performance of children born after its debut to those born before, while also considering the limitations of television technology that prevented a third of children from accessing it.
The impact of educational television, using Sesame Street as an example, on early learning is a topic of ongoing research. Economists like Melissa Carney are interested in identifying causal impacts, not just correlations. While numerous studies suggest a positive effect, Carney and her colleague Phil Levine sought to overcome potential identification and selection problems. By comparing the academic performance of children born after Sesame Street's debut to those born before, they found that the former generation did perform better in school. However, this alone couldn't definitively prove the Sesame Street effect. The researchers also discovered that a third of the children in the country couldn't access Sesame Street due to television technology limitations, providing a valuable comparison group. This research illustrates the importance of rigorous analysis in understanding the role of educational media in early learning.
Sesame Street's Impact on School Readiness: Sesame Street had a positive effect on school readiness for disadvantaged preschoolers, especially boys and African Americans, but its benefits on academic performance did not last into adulthood.
Sesame Street had a significant impact on school readiness for preschool-aged children, particularly those from economically disadvantaged backgrounds, with effects similar to those of more intensive programs like Head Start. The benefits were largest for boys and African Americans. However, the positive effects on academic performance did not persist into long-term educational completion, employment, or wages. Sesame Street's success in helping urban and minority kids might be attributed to its explicit focus on these demographics and the relatability of its characters and content. Yet, its lack of long-term impact could be due to its limited focus on non-cognitive skills development. Overall, while Sesame Street had a notable impact on early academic achievement, its benefits did not extend to later stages of education and employment.
Reimagining Education from the Start: We need a holistic approach to education, focusing on early development and addressing the achievement gap, requiring societal change and potential sacrifices.
Our approach to education needs a radical shift. We've been focusing too much on cognitive skills and formal education, but the foundation of learning begins much earlier - in the first days of life. As Dana Suskind emphasizes, we must reimagine education based on scientific evidence. The achievement gap, a persistent issue, can only be addressed by tackling education holistically, from the start. This requires a collective effort and a change in societal expectations, which might involve sacrifices. A poignant reminder of this comes from Suskind's personal story of her husband, a brilliant pediatric surgeon who lost his life saving others, emphasizing that every child deserves the same opportunities as our own. The next episode of Freakonomics Radio will explore the planning fallacy, our tendency to underestimate project timelines and costs, and how to overcome it.
