The following graphs show the distribution of scores for all students.
Presents the classroom analytics for the assignment and reports for individual students.
Below is an example of what an instructor will see for each student. Instructors can view and override the student's scores, provide feedback, and see the original response.

The first step is surveying the area, which can be done either with remote sensing or direct visual observation. There are some other methods, including aerial photography and ground-penetrating radar, which are used to locate artifacts hidden below ground, and LIDAR uses lasers to scan the surface from the air through vegetation.
After the site has been thoroughly surveyed, archeologists begin the excavation process. They start by setting up a grid and connecting the grid to a datum- a fixed reference point, often one placed by the U.S.G.S.
The next step is to dig several test pits, a small hole dug to determine the location, density, and spread of artifacts.
Then the archaeologists excavate the site using trowels, shovels, and various other tools. They carefully remove dirt and note the precise location of any artifacts found.
The soil removed from the site is screened to search for any small artifacts that may have been missed during the initial excavation.
After the site has been excavated, they fill the site back in and take the artifacts to be analyzed
These are then taken to a lab and analyzed and classified based on the archeologists' research questions. The artifacts are grouped with other artifacts of the same type.based on a variety of characteristics such as function or style.
They are then dated using radiocarbon dating, which determines the age of the artifacts.
