What is Diagnostic evaluation
want to see what skills
what’s going on previous
What is Formative evaluation
Evaluation during the program
What is Summative evaluation
Final analysis
What does it look like in the end
What does evaluation use
Measurement instruments to collect information
What does measurement theory cover
Reliability
Validity
Objectivity
Sensitivity
Reliability means
Consistency
What are the two types of reliability
Internal consistency reliability
Stability reliability
What is Internal consistency reliability
2 trials
Both measures are taken in the same day
Right after one another
What is stability reliability
Trials done on alternate days
Which reliability has a higher value
Internal consistency reliability
What is validity
Is the measure really measuring what it is meant to be measuring
What are the 3 types of validity
Internal
External
Ecological
What is internal validity
The instrument itself really measuring what is says it measures
What is external validity
Generalisability
e.g. Virtual shooting games to going into the real world
