Cognitive psychology experts can effectively rate the complexity of multiple-choice (MC) questions. This allows for increasing higher-order thinking in assessments without altering item difficulty, even when experts lack specific content knowledge.
Area of Science:
- Educational Psychology
- Physiology Assessment
Background:
- Integrating higher-order thinking into multiple-choice (MC) exams is crucial but challenging.
- Content expertise may hinder the creation of complex assessment items, as experts may not easily adopt a novice perspective.
Purpose of the Study:
- To test the independence of content expertise and cognitive complexity ratings of MC items.
- To determine if non-content experts can reliably assess the cognitive complexity of MC questions.
- To explore methods for enhancing cognitive complexity in MC questions without altering item difficulty.
Main Methods:
- Three cognitive psychology experts rated the cognitive complexity of 252 physiology MC items using a six-level matrix.
- Rasch modeling was employed to estimate item difficulties.
- Statistical analysis examined the relationship between complexity ratings and difficulty estimates.
Main Results:
- Cognitive complexity ratings were statistically independent of item difficulty estimates for 88% of the MC items.
- Modifications were identified to increase item complexity by one level without impacting item difficulty.
- Non-content experts demonstrated effectiveness in rating cognitive complexity.
Conclusions:
- Cognitive complexity of MC items can be reliably rated by non-content experts.
- A structured complexity matrix, applied by trained peer groups without domain expertise, can improve targeted item complexity.
- Higher-order thinking can be integrated into MC questions without compromising item difficulty or other test characteristics.
