Explain the steps, in order, to solving a mathematical expression.
To solve a mathematical expression, it has been widely known to use PEMDAS. This is an easy way to remember the steps. The P stands for 'parenthesis'. If the expression has parenthesis in it, you will solve whatever is in the parenthesis first. For example: in the expression 2 x (5 + 3) - 1, you would do 5+3 first because it is inside the parenthesis. The leftover expression would be 2 x 8 - 1. The E in PEMDAS stands for Exponent. So after solving parenthesis, you would look to see if there are any exponents to be solved. The M stands for multiplication and the D stands for division; these steps go together. So the 3rd step in solving mathematical expressions is to solve any multiplication or division from left to right, whichever comes first. In our example, we have 2 x 8 - 1. We have a multiplication problem, 2 x 8, to solve. We are left with 16 - 1. Which brings us to the last step of PEMDAS. The A and S go together as well and stand for Addition and Subtraction. 16 - 1 is 15, therefore our original expression, 2 x (5 + 8) - 1, simplifies to an answer of 15, using the order of operations (PEMDAS).
Using 5th grade common core standards, create a science learning goal for a 5th grade student?
The student will be able to list the title and order of the phases of the moon with 80% accuracy 3 out of 3 times given illustrated pictures of the phases.
What learning theories and theorists do you most identify with and why?
My personal learning theory is a mix between several different classic theorists, but most of all I like Bruner's theory of learning. He believed in Discovery Learning, as do I. I think that some, maybe most students learn best when they are able to work with material and induce conclusions on their own, guided by their educator. Much like constructivism, which is a theory of learning that states that students don't learn passively, rather they learn best by having experiences and interactions in the environments that they learn in. This can be adapted to work very well inside the classroom.
