Physical Development/Bronfenbrenner TIPR

Describe how the teacher implements a consideration of the students' physical development and/or Bronfenbrenner's Bioecological Model into instruction, assessment, and/or procedures. What more could/should the teacher do in this regard? Provide specific examples and be sure to include a reference in your response. 

The teenage years include periods of rapid development.  There is physical changes which include growth spurts, bone growth, body weight change, and increased endurance and strength.  There is also language development that shifts in the teen years from basic grammar to the use of language on a higher level.
Physical changes can affect the behavior of teenagers and can lead to behavioral problems.  As teachers we need to be aware and recognize that and accept a variety of behaviors in our classroom.  Teenagers also have increased appetites because of rapid growth spurts.  In the classroom I am observing, the teacher allows the students to pull out a snack.  Allowing snacks in the classroom could help improve their attention and behavior in class.  The varying growth rates can result in an excess of energy in students, so having a variety a seating options for students could prove beneficial.  Something that I would like to include in my classroom is something called 'brain breaks'.  Here is a few examples of 'brain breaks'  https://www.youtube.com/watch?v=m0uiA6UITDw  and  https://www.youtube.com/watch?v=dp0sa7Z72R8.  These 'brain breaks' can help break up the 80 minute class and can allow a 2-3 minute break during the lesson where they can get up and move.
Language development evolves over their teen years.  They should improve in abstract thinking skills and that enables them to make word associations and to understand syntax better.  The development of academic language is important in classrooms and the students ability to participate in activities and assignments.  Academic language is the language of school and is used in textbooks, essays, assignments, presentations, and assessments.  As teachers, it is important and our role to teach our students academic language to prepare them for success in college and careers. 
Urie Bronfembrenner was an American psychologist that developed the Ecological Systems Theory. The Ecological Systems Theory explains that a child develops within the context of the system of relationships that form their environment. He defines 'layers' (levels of external influence) of environment that each have an effect on a child's development. Included in the 'layers' is the Microsystem (immediate environment), Mesosystem (connections), Exosystem (indirect environment), Macrosystem (social and cultural values), and the Chronosystem (changes over time).  I feel that Bronfenbrenner's Ecological Systems Theory is in play everyday in the classroom when you interact with students that have developed in a vast array of external environments.  In addition, as teachers, we are part of the student's Mesosystem. As a teacher, instruction models, assessments, and procedures will need to be adjusted to the needs of students as you get to know and learn about them because they all have had different influences and experiences in their ecological system.
