Problem solving is a problem
which must be solved not in fast. It must be thought again and again, and then
it needs some steps to be solved. In the other hand, a non-real-life problem
could be a problem solving. For instance, “we have a figure which has 20cm of
perimeter and 8x2 cm of dimension, and then find another figure which has the
same perimeter with the largest area.” I think this is an example of a
non-real-life problem but is a problem solving because when we calculate the
area of a figure with 8x2 cm of dimension, its area is just 16cm2.
We have to find a figure which has the same perimeter with the largest area. We
cannot solve it in a fast way because we have to think again and again. We can
have a figure with 7x3 cm, but its area is just 21cm2. For a figure
with 6x4 cm, the area is 24cm2. Another figure with 5x5 cm will have
25cm2 for its area, and it’s the largest one. So, problem solving is
not merely about real-life problem, but it’s a problem which needs some steps
to be solved.
Based on my experience, I don’t
remember when the first time I was given a problem solving is. However, in
Senior High School I was given some problems solving when I learned about
linear equation system. That’s the only part which I remember in learning by
problem solving because the question were real-life, and it needed some steps
to be solved. May be, when I learned about logarithm, exponential, quadratic
functions, I had learned about non-real-life problem solving. However, so many
questions to drill and practice but they don’t need many steps to be solved, so
most of them are not problem solving.
Learning with problem solving is
really challenging. It challenges my thought to “think inside and outside the
box.” I had to think in different ways to beat it, so that it is bore less. If
I compare with non-problem solving, it’s really boring because just by one or
two steps we will find the answer, so it’s not challenging at all. In my
conclusion, learning by problem solving is much more advantages than learning
by non-problem solving. In another way, I’ll try to shape my students’ logical
thinking by problem solving, so that I will provide as many as problem solving
in my teaching.
