Learning Objectives
• The negative effects of screen time on children’s social-
emotional and cognitive development.
• The health implication of too much screen time in young
children.
• The importance of real life experiences and face-to-face
interactions to the overall development of young children.
NEGATIVE EFFECTS OF
SCREEN TIME ON CHILDREN’S
SOCIAL-EMOTIONAL &
COGNITIVE DEVELOPMENT
Language Delay
In children under 3, the use of screen media is linked to a
delay in language acquisition. Research shows that adolescents that
watched 1 additional hour of television each day as toddlers have
lower math scores and poorer school achievement.
Fast-Paced Television
• Research shows that just 20
minutes of a fast-paced,
animated show can negatively
impact executive functioning
skills in young children.
• Executive functioning skills
include attention span,
delaying gratification, self-
regulation, and problem
solving.
HEALTH IMPLICATION
FOR TOO MUCH
SCREEN TIME IN
YOUNG CHILDREN
TV and Sleep Problems
• Studies have shown that a greater
amount of TV time watched per
day is associated with and
increase in both irregular naptime
and bedtime schedules.
• The same study showed that the
amount of TV viewed overall by
children during bedtime had a
heavy association with sleep
disturbances.
• The areas of sleep that appeared to
be most impacted were: resistance
to bedtime, later bedtimes, anxiety
around sleep and less overall
sleep.
Excessive Screen Time & the Brain
• Research states there has been shrinkage in the part of the brain
(gray matter) where processing occurs when there is a
internet/gaming addiction.
• Studies show that when video games are being played, the brain
produces a natural substance called dopamine which your body
craves. The changes in the brain caused by this release of
dopamine are similar to what happens when a person craves
drugs.
• With that said, immoderate amounts of screen-time appear to
damage brain structure and function.
REAL-LIFE
EXPERIENCES
AND
FACE-TO-FACE
INTERACTIONS MATTER
 The research is clear: infants, toddlers,
and young children learn best through
interactions with the people in their
environment when all of their senses
are in use.
 Real world, hands-on activities such as
gardening, cooking and woodworking
support children’s creative play where-
as screen-time eliminates creativity.
 In early childhood, the developing brain
benefits the most when children are
talked to, read to, and played with.
 Children enjoy when they are given
opportunities to engage meaningfully
with the adults and peers in their
surroundings.
Books are Best!
• “Nothing stimulates the intellect like
a good book” –Richard Lewis, UK
• Books require children to use their
imaginations more than electronic
devices.
• E-readers and other devices distance
young children from the real-world
whereas books provide children with
hands-on experience.
• Paper books allow children to stay
engaged with a story more than
devices because devices have
buttons to push and games to play.
Importance of Hands-On, Creative Play
• Caregivers are more likely to provide more physically active
experiences and plenty of time for child initiated play when screen-
time is not an option.
• Children are lacking fine motor development in their hands when
they start school due to more time spent with screens and less time
spent utilizing their bodies in meaningful ways.
• Open-ended hands-on exploration and play fosters experiences for
children to develop their creativity and problem solving skills.
• Digital technologies limit opportunities for children to engage their
curiosities because of the parameters that are already set with
technological devices.

  • 29. Learning Objectives • The negative effects of screen time on children’s social- emotional and cognitive development. • The health implication of too much screen time in young children. • The importance of real life experiences and face-to-face interactions to the overall development of young children.
  • 30. NEGATIVE EFFECTS OF SCREEN TIME ON CHILDREN’S SOCIAL-EMOTIONAL & COGNITIVE DEVELOPMENT
  • 31. Language Delay In children under 3, the use of screen media is linked to a delay in language acquisition. Research shows that adolescents that watched 1 additional hour of television each day as toddlers have lower math scores and poorer school achievement.
  • 32. Fast-Paced Television • Research shows that just 20 minutes of a fast-paced, animated show can negatively impact executive functioning skills in young children. • Executive functioning skills include attention span, delaying gratification, self- regulation, and problem solving.
  • 33. HEALTH IMPLICATION FOR TOO MUCH SCREEN TIME IN YOUNG CHILDREN
  • 34. TV and Sleep Problems • Studies have shown that a greater amount of TV time watched per day is associated with and increase in both irregular naptime and bedtime schedules. • The same study showed that the amount of TV viewed overall by children during bedtime had a heavy association with sleep disturbances. • The areas of sleep that appeared to be most impacted were: resistance to bedtime, later bedtimes, anxiety around sleep and less overall sleep.
  • 35. Excessive Screen Time & the Brain • Research states there has been shrinkage in the part of the brain (gray matter) where processing occurs when there is a internet/gaming addiction. • Studies show that when video games are being played, the brain produces a natural substance called dopamine which your body craves. The changes in the brain caused by this release of dopamine are similar to what happens when a person craves drugs. • With that said, immoderate amounts of screen-time appear to damage brain structure and function.
  • 37.  The research is clear: infants, toddlers, and young children learn best through interactions with the people in their environment when all of their senses are in use.  Real world, hands-on activities such as gardening, cooking and woodworking support children’s creative play where- as screen-time eliminates creativity.  In early childhood, the developing brain benefits the most when children are talked to, read to, and played with.  Children enjoy when they are given opportunities to engage meaningfully with the adults and peers in their surroundings.
  • 38. Books are Best! • “Nothing stimulates the intellect like a good book” –Richard Lewis, UK • Books require children to use their imaginations more than electronic devices. • E-readers and other devices distance young children from the real-world whereas books provide children with hands-on experience. • Paper books allow children to stay engaged with a story more than devices because devices have buttons to push and games to play.
  • 39. Importance of Hands-On, Creative Play • Caregivers are more likely to provide more physically active experiences and plenty of time for child initiated play when screen- time is not an option. • Children are lacking fine motor development in their hands when they start school due to more time spent with screens and less time spent utilizing their bodies in meaningful ways. • Open-ended hands-on exploration and play fosters experiences for children to develop their creativity and problem solving skills. • Digital technologies limit opportunities for children to engage their curiosities because of the parameters that are already set with technological devices.

Editor's Notes

  1. Human innovation in action! People have to need it – people have to want it – in order for technology to happen.
  2. When we study Science, we look at it in different subject areas. Earth Science Biology Chemistry Physics Astronomy Meteorology Other specialty areas such as Quantum Physics and Computer Science
  3. Just like with science, when we study technology we look at it in the following categories These forms of technology will be discussed throughout the presentation.
  4. Information Technology is the process of gathering and storing data to be used in various forms. Provides streamlined access to vast sources of information Allows us to produce more accurate forms of communication Includes expanded resource choices Enables us to retrieve data in seconds
  5. Impacts slides will provide one positive and one negative example. There should be a class discussion about how other technologies impact the student, school, community, world, etc. COMPUTERS – Use of a computer to easily gather and store data OBSCELENCE –Machines must be maintained and upgraded Yellow Pages book compared to finding phone numbers on line – or stored in the memory of a phone.
  6. Communication Technology is a process of giving or exchanging information. Provides streamlined publishing techniques and allows us to produce more accurate drawings Includes expanded entertainment choices Enables us to contact people thousands of miles away
  7. CAD – Using a computer to generate more accurate drawings in a shorter period of time PAPER USAGE – People tend to create and print more documents
  8. Bio-related Technology Pharmaceuticals Artificial limbs Genetic engineering Hydroponics Imaging devices Cardiovascular devices Ethics The Human Genome Project (HGP) was one of the great feats of exploration in history. The HGP gave us the ability to, for the first time, to read nature's complete genetic blueprint for building a human being. Agricultural biotechnology is a range of tools, including traditional breeding techniques, that alter living organisms, or parts of organisms, to make or modify products; improve plants or animals; or develop microorganisms for specific agricultural uses. Modern biotechnology today includes the tools of genetic engineering. Biotechnology provides farmers with tools that can make production cheaper and more manageable. For example, some biotechnology crops can be engineered to tolerate specific herbicides, which makes weed control simpler and more efficient. Other crops have been engineered to be resistant to specific plant diseases and insect pests, which can make pest control more reliable and effective, and/or can decrease the use of synthetic pesticides. These crop production options can help countries keep pace with demands for food while reducing production costs. Advances in biotechnology may provide consumers with foods that are nutritionally-enriched or longer-lasting, or that contain lower levels of certain naturally occurring toxicants present in some food plants. Developers are using biotechnology to try to reduce saturated fats in cooking oils, reduce allergens in foods, and increase disease-fighting nutrients in foods. They are also researching ways to use genetically engineered crops in the production of new medicines, which may lead to a new plant-made pharmaceutical industry that could reduce the costs of production using a sustainable resource. http://www.usda.gov/wps/portal/!ut/p/_s.7_0_A/7_0_1OB?contentidonly=true&navid=AGRICULTURE&contentid=BiotechnologyFAQs.xml
  9. DISEASE – Research on controlling and eliminating diseases DISEASE – Not all cultures embrace use of vaccines and thus disease spreads
  10. FOOD – More variety, healthier choices, processed so that it is safe and tastes good GENTICALLY ALTERED CROPS – Potential for weeds and insects to mutate and become resistant
  11. Environmental Technology is study of processes to control waste, soil erosion, reducing sediment in waterways, conserving water, and improving water quality.
  12. DISEASE – Reduces chance of disease from pollution and chemicals
  13. Natural (found in nature) or Synthetic (human-made) Examples of Manufacturing Technology: Clothing, entertainment devices, automobiles, chemical products, lumber, steel, food Examples of Construction Technology: Houses, high-rise buildings, bridges, roads, dams, schools
  14. Decking - Recycled plastic and saw dust to make simulated wood deck materials Car bodies can be made from plastic instead of metal. The B-2 bomber uses high tech composites to achieve its stealth capabilities. The materials that form a composite are not changed. They work together to create a new material with desirable qualities.
  15. Materials technology enables us to design durable construction components. The ability to design and adopt better-performing, energy-saving, cost-efficient materials with known durability characteristics is key to our construction industries future.
  16. Traveling long distances faster Use of energy, pollution
  17. Technological products and systems need energy to function. The availability of energy often determines the development of technology.
  18. In the last slide, we stated that energy is the capacity to do work. In this definition, we are referring to potential energy. Once we have potential energy, we put it to use by converting it into kinetic energy. We have power when we can apply kinetic energy over a period of time to do work. Power makes work easier.
  19. Burning fossil fuels causes greenhouse gases associated with global warming.
  20. Nanotechnology is the creation of functional materials, devices and systems through control of matter on the nanometer length scale (1-100 nanometers), and exploitation of novel phenomena and properties (physical, chemical, biological, mechanical, electrical...) at that length scale. For comparison, 10 nanometers is 1000 times smaller than the diameter of a human hair. A scientific and technical revolution has just begun based upon the ability to systematically organize and manipulate matter at nanoscale. http://www.ipt.arc.nasa.gov/nanotechnology.html
  21. MOLECULAR MANUFACTURING – Faster diagnosis of diseases MOLECULAR MANUFACTURING – Weapons and surveillance devices can be made small, cheap, and powerful.
  22. Because screen time is a fact of life for millions of American children these days, it is important that families and caregivers are aware of the impacts of screen time on the development of children and that they limit screen time and increase children's interactions with their 3-D environments, families and peers. On any given day…. 29% of babies under 1 year watch TV and videos for an average of 90 minutes. 64% of children 12-24 months watch TV and videos averaging just over 2 hours.
  23. 1- Areas affected include the frontal lobe where executive functioning happens as well as impulse control. Volume loss was also seen in the striatum, which is involved in reward pathways and the suppression of socially unacceptable impulses. A finding of particular concern was damage to an area known is the insula, which is involved in our capacity to develop empathy and compassion for others and our ability to integrate physical signals with emotion. Aside from the obvious link to violent behavior, these skills dictate the depth and quality of personal relationships.    2-translates into loss of communication within the brain, including connections to and from various lobes of the same hemisphere, links between the right and left hemispheres, and paths between higher (cognitive) and lower (emotional and survival) brain centers. White matter also connects networks from the brain to the body and vice versa. Interrupted connections may slow down signals, “short-circuit” them, or cause them to be erratic (“misfire”). 3-Much of the damage occurs in the brain’s frontal lobe, which undergoes massive changes from puberty until the mid-twenties. Frontal lobe development, in turn, largely determines success in every area of life—from sense of well-being to academic or career success to relationship skills. Use this research to strengthen your own parental position on screen management, and to convince others to do the same.
  24. Promoting creative play is the most effective way to engage children in their 3-D environment and influence their learning and behavior.
  25. Kids lose the tactile experiences of handling a traditional book, turning pages, or sharing their favorites with friends. Real books give children and adults more opportunities to build relationships. Research shows that with devices, parents tend to be more controlling and worried about what their children are doing rather reading the story and staying engaged.
  26. According to one elementary school principal, he has hired an occupational therapist to work with all of his students to improve the motor development of the hands so that young children can do things like hold scissors or complete arts/crafts which then leads to the development of the ability to write. Research shows that as a society, our creativity is declining and yet a Global survey of 1500 CEO’s names creativity as the number one attribute for leadership.
