Study Notes
Significant Culminating Task and Success Indicator
- At the end of the lesson, students should be able to demonstrate their knowledge and skills in selecting appropriate criteria and analyzing results from non-traditional forms of assessment like performance tasks, scales, and checklists.
- To be considered successful, students must satisfy at least the following indicators of success:
Quantifying Results from Rubrics
- In creating rubrics, scales are used to represent the degree of performance, ranging from high to low proficiency.
- Examples of degrees of proficiency with corresponding points include:
- Beginner (1 point) to Very Proficient (4 points)
- Poor (1 point) to Very Good (4 points)
- Minimal (1 point) to Complete (3 points)
- Never (1 point) to Always (5 points)
- Novice (1 point) to Superior (4 points)
- Inadequate (1 point) to Excellent (4 points)
- The reliability of assigned points can be determined by using multiple raters or judges to rate the performance, and then calculating the consistency of the ratings using a coefficient of concordance, such as Kendall's w coefficient of concordance.
Using Kendall's w Coefficient of Concordance
- To calculate Kendall's w coefficient of concordance, first compute the scores given by each rater, then sum the ratings for each demonstration.
- Calculate the mean and sum of squared differences, then substitute these values into the Kendall's w formula.
- The resulting coefficient of concordance indicates the level of agreement among the raters.
Quantifying Results from Scales and Checklists
- Scales can be used to measure non-cognitive dimensions of students' behavior, with higher scores indicating a higher frequency of the behavior.
- Types of scales include:
- Linear numeric scale, which provides a range of rating options with descriptors for the extreme points.
- Semantic scale differential, which uses two opposite adjectives to describe the object or behavior.
- Graphic scale, which uses illustrations to represent the degree of presence or absence of a characteristic.
Quantifying Results from Portfolio Assessment
- Portfolio assessment data can be both qualitative and quantitative.
- When assessing portfolios using a quantitative approach, scales and rubrics can be used.
- Criteria for assessing portfolios include:
- Completeness of the entries
- Accuracy of the reflection
- Other criteria specific to the portfolio being assessed.
