GRIT 2.1 is a system for securely displaying grades over the Web. GRIT 2.1 is an improved version of GRIT 2.0.
As before, GRIT 2.1 comprises of two parts:
grit not grit2.1 or grit2.0) to be used by the TAs to enter data into the database.
To see a list of available commands type grit with no arguments. You can also get a more detailed explanation by typing grit -help.
For problems, suggestions, and other questions please email: operator [at] cs.umn.edu
To get access you need to email operator [at] cs.umn.edu . With the following information:
* We suggest only activating one section unless you want to keep the statistics generated for each section separate. It requires more work on your part because you will need separate gradefiles for each section.
(back to top)The Grade file should contain the following information:
The course information is pretty easy. It starts with the keyword course: followed by the course designator, course number, section number, quarter code and year. The quarter codes are:
Example:
course:CSCI9998.1.S.1999
OR
course:CSCI3322.1.SU.1999
The template begins with the keyword template:. It has the following format:
template:(tag-element)[:(tag-element)]
tag-element has the format: (tag)=(maxscore) [, order =(order)][, weight = (weight)]
(tag) is a label for a specific test/homework.
(maxscore) is the maxscore for that tag.
The order field is optional and lets you order the printout of the various tags you assign. The webpage will print them out from lowest to highest.
The weight is an optional field that lets you assign a percentage to each tag as to how it will affect the overall total grade.
Example:template:hw1=20,order=1,weight=.90
:hw2=20,order=2,weight=.10
The students scores begin with a student id, and have the following format: (id):(tag)= (score)[, comment = (comment)]
(id) is a student id.
(tag) is a tag from the template.
(score) is the students score for tag
(comment) is a string and is optional.
The following are all valid grit grade files:
Run grit with the filename of the gradefile as an argument.
( % grit gradefilename )
The grit program is a setuid program so you may get an error opening the file for input. If you do, change the permissions on the file so it is readable by everyone. Once you have loaded your file, you should change it back so that others can NOT read it. You also need to make sure that the path to the file is executable by everyone, the file can not be read if the user can not get into the directory.
(back to top)It is very important that you are aware of the basic security requirements when using grit. The files you upload to grit should not be world readable. They should only be readable by you and, if necessary, the professor and other class ta's. You should not store these files in class web space. If the file is world readable, anyone can access the file with a web browser. You do not need to create a link to the file to make it accessable.
Incorrectly setting the permissions on grade files is a violation of the Family Educational Rights and Privacy Act (FERPA). Violating this policy is a serious offense. Please contact Systems Staff if you have any questions or need assistance with setting the permissions on you grade files. We would be more than happy to help.
The following directions demonstrate how to correctly set the permissions on your grader file.
Assuming your group was F04C1101 and your file is ~mein/grades/grader.dat
Change the group for the directory and the file:
%chgrp F04C1101 ~mein/grades
%chgrp F04C1101 ~mein/grades/grader.dat
Change the permissions so your group can access both the file and the directory in which the file resides.
%chmod 701 ~mein/
%chmod 770 ~mein/grades/
%chmod 770 ~mein/grades/grader.dat
If members of your group will need to add files to the directory in which the grader file resides, turn on the sgid bit for that directory. This way, when other members of the group add a file to the directory, the group will always be set to the group assigned to that directory. You do NOT want to have a file containing student grades readable by the "grads" group. If this occurs, all CS&E graduate students will be able to read the file.
chmod g+s ~mein/grades/(back to top)
Along with the built in functions that GRIT offers, a couple of students have submitted the following program to format the output of grit. The script is /project/grader/reportGrades.pl
The following commands can be used together or separately. Each definition shows the single usage. Here is an example of the commands used together:
grit -show -graph -total CSCI9998.1.S.1999
For each of these commands, if you do not specify a gradefile you will get a list of gradefiles you have access to.
Example:grit -show CSCI9998.1.S.1999
When you specify a course it prints out each tag along with the current statistics for that tag. It also prints out a list of all scores entered for that course. (Ordered by student ID)
Example:grit -graph CSCI9998.1.S.1999
When you specify a course it prints out a graph for each tag. It graphs how many students got specific scores.
Example:grit -total CSCI9998.1.S.1999
When you specify a course it prints out Weighted totals for each student as well as their overall percentage.
Example:grit -delete CSCI9998.1.S.1999
The delete command takes a coursename as input and removes all scores and tags for the specified course. If you do not specify a course name, a list of courses you have access to will be displayed.
Note: This will not remove your access for a given course.
