View One: This first map shows the schools we used. Here you'll find all lausd high schools, six low scoring non LAUSD L.A. county schools and six high scoring non LAUSD L.A. county schools.
View One-A: Zooming in we can see that the map of LA county is divided up into tracts. Tracts are a geographical location that the census bureau has used to divide up the entire united states. There are even smaller census gathering areas that are called blocks. A" block" is approximately a four city block area.
View Two: This map shows the high schools we used with their exit exam math scores, 1 to 99 (highest).
View Three: This map shows the schools where the math scores have been converted to a ranking system. The higher the number, the better the school did on the test. This was done to more easily show how each school did less confusing than lots of numbers.
View Four: This map shows the high school exit exam scores for English language. It’s similar to View Two because it used the actual scores on a 1- 99 scale.
View Five: This is similar to View Three where the 1-99 scores have been converted to a 1 to 9 rank.
After entering the data and viewing the scores we wanted to know why some areas of the county had higher exit exam scores than others. We used data from the census bureau to create maps that showed both the scores and the demographics of the area. Demographics are data figures such as # of people, income, poverty, races and language spoken and many other things that the government gathers data on.
View Six: This is a demographic map showing the white population in LA county. The darker the color the higher the number of white persons that lives in that tract.
View Seven: This is a demographic map showing the exit exam math ranking numbers (1-9) for the white population.
View Eight: This map shows Hispanic persons over the exit exam math rank.
View Nine: This map show Black persons over the exit exam math rank.
View Ten: This map shows Asian persons over exit exam math rank.
One problem we wanted to investigate was the relationship between uncredentialed teachers and exit exam test scores. Among the fields we added to our GIS database was uncredentialed teachers at each school. The following maps were created using data from the official LAUSD web site. We do not have this data for the 12 non-LAUSD high schools.
View Twelve: This map shows the percentage of uncredentialed teacher only. The larger the school symbols the more uncredentialed teachers at the high school.
View Thirteen This map shows the number of uncredentialed teachers at each high school. Note there are some schools with no uncredentialed teachers.
View Fourteen: This map shows the percentage of uncredentialed over hispanic persons in each tract.
View Fifteen: This maps shows the White persons per tract with the percentage of uncredentialed teachers symbolized by blue triangles. The larger the triangle the higher the percentage of uncredentialed teachers.
View Sixteen: This maps shows the median income compared with uncredentialed teachers.
Conclusions: Neighborhoods with high percentages of Black and Hispanic people have lower test scores and have higher percentages of uncredentialed teachers.
