If we consider our ancestors and the evolution of our brain, we are descendants of nomadic people spending the majority of the time hunting and gathering with the majority of their time spent outdoors. Children played outside and learned through social play interactions and imitation of older children and adults.
Now, I am sure you are going to question what this has to with children in today's society. Our brains are still 'wired' to learn through movement which is evident in a child's achievement of developmental milestones. An infant child turns his head to localize the sound of his mother's voice. As a baby rolls onto his belly and activates his spinal muscles and coordinates muscles on both sides of the neck to extend symmetrically to maintain his head in midline. As he pushes his chest off of the ground and comes up onto hands and knees, he has an opportunity to learn more about his surrounding environment. As he rocks back and forth he provides his joints with information about where his body ends and the external environment begins. He can now free his hands and move into a sitting position to manipulate objects at midline. His eyes converge together to examine toys and he will bring objects to his mouth to learn more about them. As he starts to crawl, he will need to pair the left and ride sides of his body instead of pairing top and bottom when he was rocking (children that have difficulty separating the left and right side will often attempt crawling but will end up 'bunny hopping'. These children often abandon crawling at an early age). The external environment (mom calling his name, a toy lying just out of reach, a sibling running into the other room) will encourage baby to crawl. He will learn to diverge and converge his eyes as he crawls toward objects. He will then start to pull up to stand, cruise along furniture and other objects in the environment, and then walk. This upright position will free up the child's hands for more opportunities for object manipulation and will provide a more detailed perspective to the auditory and visual systems.
Unfortunately, more and more children are not going through these stages within the developmental norms that were established 15-20 years ago. There are many factors that contribute to this latency in development, however, I am going to focus on the environmental factors that can be changed for the sake of this blog. These factors include seats that prop children up in seated positions before their musculature is able to support their body, play yards, bouncy seats, exersaucers, car seats that snap in and out of the car, videos designed to keep baby occupied and quiet. Young children are being tuned out with computers, tablets, smartphones, and video games. This type of play does not promote social engagement, social pragmatics, or social problem solving leading to difficulties with a child's overall social interaction with other children. Video games do not provide the same movements required for fine motor manipulation and development of the fine hand musculature.
Babies learn through movement and exploration of the environment. Baby needs lots of opportunity for tummy time. By getting down on the floor with your child to you motivate them, encourage them, and provide opportunities for engagement, communication, and play. Children need to be given the opportunity to run, jump,climb, and swinging to continue development of body awareness and bilateral coordination and coordinate the sensory system.
Implications for the Classroom:
- Under development of spinal musculature makes it difficult for a student to sit still in their seat, stand still in line, or do written work without stabilizing themselves on the desk (leaning) or wrapping legs around their chair
- Poor coordination between eye convergence and divergence makes copying long passages from the board difficult
- poor sound localization, habituation of background noise, tuning in to salient auditory information (the teacher speaking) leads to difficulty following directions and completing tasks
- Poor development of hand musculature leads to difficulty with self-help skills such as tying shoes, snapping snaps, buttoning, and zipping. This can also lead to problems with drawing and writing in grade school.
