Here's what I did, and really like the way it works.
- I created a spreadsheet for my rubric
- I entered in the appropriate headings and descriptors, to make it look like a rubric.
- Here's the technical stuff. I added a formula and conditional formatting to account for some changes.
- I added a column titled "total"
- I put this formula into the first cell and copied it down the column. =if(right(B3)="@",4, if(right(C3)="@",3, if(right(D3)="@",2, if(right(E3)="@",1,0))))
- all this formula says is that if the @ symbol is to the right of all the text in the referenced cell, then apply the value 4,3,2, or 1. If it is not there, apply the value 0.
- Further down the spreadsheet there is a small formula to calulate a total and adjust the score out of a 100%.
- This cell uses the following formula ="Grade: "&(Sum(F1:F23)/80)*100 &"%"
- which tells the spreadsheet to add the text Grade, calculate a percentage of teh earned values, and attach a % symbol to the returned value. This is only for ease of student viewing. As I collect the values for my grading purposes I would use the raw tally for the total available.
- Below is a copy of my rubric Used for grading Lab Reports. To get a full feel of the spreadsheet you will need to "make a copy" to click around in the cells and play with the formulas.
- The last detail is to add the conditional formatting option to highlight the appropriate cell a specific color. You can see that the first box of the rubric is purple, because it contains the @ symbol at the end of the text, which also triggers the formula to apply 4 points to the total.
Again, I know goobric will do this automatically, but the rules for which you need to "assign" work sometimes don't' match with they way that I have students doing assignments. I simply fill out the rubric then click print, and select save as pdf, and change the destination folder to the synced Google drive folder for that student.
