How does Edulastic support standards based grading?

Follow

Edulastic translates student performance in a specific standard to a standards based grade. This is done using a customizable standards based performance band and a standards proficiency calculation method. As a district administrator, you can configure the performance band and a standards proficiency calculation method that is most suited for your teaching needs.

Standards Based Grading Scale

The standards proficiency scale assigns a grade to each standard for each student. By default the customizable Standard based grading scale is a 4 point scale with 4 mastery grades:

  1. Exceeds Mastery (4 points) with a 90% cutoff
  2. Mastered (3 points) with a 80% cutoff
  3. Almost Mastered (2 points) with a 60% cutoff
  4. Not Mastered (1 point) - below 60%

 

The above scale, cut score, report color and short name can be easily customized by a district admin in the settings tab of the district.  

Mastery Calculation Method

Edulastic computes students standard based score for each standard by isolating the questions with the specific standard alignment. This can be easily understood using an example of a student's performance in assessments with multiple standards:

 

Standard Alignment  Assessment 1 Assessment 2 Assessment 3 (recent)
7.RP.A.1  3/6 (50%)    4/5 (80%)
7.RP.A.2  3/4 (75%) 5/10 (50%) 4.5/5 (90%)
 Total Score  6/10 (60%) 5/10 (50%) 8.5/10 (85%)

 

In the above example, the student's total score in the assessments is broken down into individual standards based scores. The cut scores are then used to award standard based grades as follows: 

Standard Alignment  Assessment 1 Assessment 2 Assessment 3 (recent)
7.RP.A.1  1   3
7.RP.A.2  2 1 4

 

Edulastic now calculate mastery score for standard by combining  scores from prior assessments. This can be done by selecting one of the mastery calculation methods shown below

  1. Most Recent [Default Criteria] - The latest assessment is used to determine student mastery grade. In the above example, student has a mastery grade of 3 (Mastered) for 7.RP.A.1 and 4 (Exceeds Mastery) for 7.RP.A.2
  2. Decaying Average - This method formula recognizes that the most recent score is more representative of the student's current mastery and thus puts more weight on the most recent score. By default Edulastic assigns 65% weight for the most recent score and 35% for all prior scores. In the above example, for 7.RP.A.2 the mastery score is computed as follows:
    1. Mastery Score (for 7.RP.A.2) = 0.65 ✕ 4 + 0.35 ✕ [(2+1)/2]=3.125 (or Mastered)
    2. You can change the weight assigned to the most recent assessment in district settings
  3. Moving Average - The average of the 5 most recent scores is used as the overall score for the Standard. You can change the number of assessments that is used for calculating the moving average.
  4. Maximum -The latest standard score is used to determine student mastery grade
  5. Average - Simple average of standard score achieved by the student in all assessments.

  6. Power law - Edulastic interpolates the data and creates a best fit function is used to estimate the student's current level of mastery based on performance and growth for the student.
  7. Mode - Most frequently achieved score for the standard is used

 

How do I customize mastery grading scale?

The grading scale, cut score, report color and short name can be easily customized by a district admin in the settings tab of the district.

The standard scale would be used to determine the standards based score of student in assignment. You can define the mastery levels and cut scores using the performance threshold number. 

To create a new grading scale or edit existing scales, use the green function icons to edit, clone, delete, and create new grading scales.
