Bizzy, I have taken this paragraph and rewritten it to let you see what I meant by being less wordy and better organized.

My study of Human Development will be useful in working with children.
The course,Human Development 307I Childhood through Adolescents, explained the cognitive and social skills of children six to seven years old. This class will help me understand how children develop in other areas as well. My current course, Child Development and Family Studies 411 Individual Child Study and Guidance, will teach me how to provide guidance to children in family and community settings. Children bring to school the environment in which they live, and teachers must be able to recognize and work with inherent problems. ( Human Development 470 will give me the tools I need to be a good professional and to succeed with my career goals in the future. ) This sentence doesn't say anything. What tools will it give you specifically?
These courses will give me the training required to approach children with confidence and competence.

I believe my training in the field of Human Development will be useful in my practicum site because the children there are developing into future adults. The course I took called, Human Development 307I Childhood through Adolescents, explains the cognitive and social skills children have when they are about six to seven years old. The knowledge obtained from this class will help me understand how children develop in other areas as well. The current course I am taking called, Child Development and Family Studies 411 Individual Child Study and Guidance, will teach me how to provide guidance to children in family and community settings. In addition, the Human Development course 470 will give me the tools I need to be a good professional and to succeed with my career goals in the future.
