Evaluating Your Own Performance
• Pre-test and Post-test
• Indicator of your performance
• Feedback for possible Lesson Plan revision
22
Purpose of Testing
• Why Test?– Improve Teaching/Learning Process– Aid in Instruction
• Gaps in Learning• Gaps in Instruction
– Reinforce Learning• Stimulate Thought• Encourages Learning• Improves Study Habits
23
Purpose of Testing (contd)
• Tests Provides– Incentives
• To Study• Sense of Competition
• Assign Grades– Valid– Comprehensive– Differentiating
Performance Testing
What is the best way to determine if students can perform a specific task?
Have them do it, or at least simulate the activity.
Require actions such as identification, simulation and work samples.
25
Performance Testing (contd)
• Psychomotor Skills– Measure specific skills that require action
• Report writing
• Handling tools
• Weapons
• CPR
• Approach to emergency scenes
26
Performance Testing (contd)
• Psychomotor Skills– Practical Exercise
• Practice skills and get feedback and coaching
– Performance Exam• Demonstrate proficiency under controlled
conditions
27
Performance Testing (contd)
• Advantages– Face Validity
– Job Related
– Reliable
– Observe Individual Differences
• Disadvantages– Not Comprehensive– Time Consuming– Tools, Equipment,
Material– Design Difficult– May be Unreliable
28
Performance Testing (contd)
• Construction and Use– Step One: Specify Performance
Objective to be measured– Step Two: Select Rating Factors (Use a
Form)– Step Three: Prepare directions– Step Four: Try out if new– Step Five: Use more than one rater– Step Six: Follow procedures– Step Seven: Give immediate feedback– Step Eight: Rotate teams and
members

Written Tests
Often limited to lower cognitive learning levels of recall and recognition
No set “correct” response. Can vary with each student’s solution to the problem.
OBJECTIVE
SUBJECTIVE

Written Tests (contd)
• Classified According to Purpose– Prescriptive
• Measuring readiness• Determining placement
– Progress• Measure improvement• Diagnose learning difficulty
– Comprehensive• Measure terminal performance
31
Written Tests (contd)
• Delivery and Use of Test– Instructions– Security– Administration
• Before: notify, tell when, what, how and what they should bring
• During: good environmental conditions, relieve stress, encourage to do own work
• After: give results, review and evaluate test
32
Characteristics of a Good Test• Measures the material taught
• Yields consistent results
• Scorer bias eliminated
• Liberal sampling of course materials
• Detects small differences in student achievement
• Effective/efficient administration
