Final Flashcards
item-level analysis
Selected-response items
Constructed-response items
Performance tasks
test-level analysis
Scores from tests and quizzes
Homework marks
Performance assessment marks
item difficulty
how many students are able to answer the question correctly
easy items
p higher than 0.9
p value (selected response)
proportion of items that are correct. Number of correct answers/number of students taking the test
difficult items
p lower than 0.5
moderate items
p between 0.5 and 0.9
p value (constructed response)
sum of marks on the item/ (number of students) x (Max possible mark on the item)
high discrimination
over 0.2
item discrimination
Whether an item can distinguish low achieving students and high achieving students
Discrimination equation
(number of correct answers/upper group) - (Number of correct answers/lower group)
distractor functioning
distractors are incorrect response options.
Developing high-quality (e.g., plausible) distractors can be a challenging task
low discrimination
under 0.2
reliability
indicates whether an assessment can give consistent
results for students
summative reliability
between 0.8 and 0.9
marks
scores on individual summative assessments
grades
aggregates of marks, a score, or letter that is representative
of a students work over a period of time
numeric grading
Easier record keeping, more precise measurement
letter grading
Interpretable right off the box, Mostly standardized. Comparable.
grading systems
typically consists of the following steps:
1. Analysis of test items and scores
2. Assigning a grade
3. Reporting student performance
absolute grading
Also known as criterion-referenced
grading
Focus:
Each student’s performance
vs.
Some specified standard
relative grading
Also known as norm-referenced
grading
Focus:
Each student’s performance
vs.
Performance of his/her peers
report cards
should provide straightforward
information about what students:
* know
* can demonstrate relative to the graded curriculum
* need to do to achieve/maintain mastery
SLA’s and PATs
- determine if students are learning what they are expected to learn
- provide information to Albertans regarding how well students have achieved
provincial standards at given points in their schooling - assist schools, school authorities, and the province in monitoring and improving
student learning.
