One strength of this essay is your use of supporting evidence. However, you will need to work on your own basics if you want to pass the CBEST. You strive for high style, but this is undercut by very many very basic errors, such as use of the singular form of a word when the plural form is needed. Here are a few corrections:
Newpaper columnists and school educators express different opinions
concerning whether it is a good or bad policy
for public schools.
The Back to Basic curriculum improves student
s' skill
s , minimizes school expenditures and strengthens students
' competitiveness.
NB:
student = one student
students = two or more students
student's achievement = the achievement of one student
students' achievement = the achievement of two or more students
Skilled professionals are the survivor
s in today's realm.
Just imagine your school district spend
s money in changing a History book every
seven years.
Has American history changed that much since we
were preschoolers? Is it justifiable to continue changing books amidst the tremendous budget cut
s for education? Of course not!
By the way, I can't believe you are arguing against updating textbooks. In so doing, you showcase your own lack of knowledge. You may want to rethink taking such stances if you will be taking the CBEST in hopes of gaining a job in education.
With the Great Depression soaring high this year,
First of all, the Great Depression was an historical event. Some people liken what's happening now to the Great Depression but we are not in the Great Depression now. Second, depressions can't soar. A depression goes downward, not upward.
In summary: Your writing is creative and you have used sources well, but you need to be much more careful about the basics in order to pass the CBEST.
