Reasoning about cases complex skill:
• Domain complexity- Interpretation legal concepts- Using external sources / knowledge about the structure- Adversarial reasoning - High number of non routine task aspects
• Students’ knowledge structures
Problematic for preferred instructional method: ‘learning by doing’
![Page 3: Learning to solve legal cases: The effects of instructional support](https://reader036.vdocuments.mx/reader036/viewer/2022062323/56816050550346895dcf7a04/html5/thumbnails/3.jpg)
Is ‘learning by doing’ effective for learning ?
Previous research suggests high cognitive load caused by:
• Incomplete conceptual knowledge • Search process
(Nievelstein, Van Gog, Boshuizen, & Prins, 2008; in press)
![Page 4: Learning to solve legal cases: The effects of instructional support](https://reader036.vdocuments.mx/reader036/viewer/2022062323/56816050550346895dcf7a04/html5/thumbnails/4.jpg)
Instructional support
• Optimize cognitive load; more capacity for processes effective for learning - focus on important task aspects- trying to understand the underlying legal framework- intention to improve reasoning performance
• Cognitive load is measured by the mental effort scale

Experiment 1
79 first-year law students Tilburg University
• Pre-test• 2 Training cases• 1 Test case • Mental effort
![Page 6: Learning to solve legal cases: The effects of instructional support](https://reader036.vdocuments.mx/reader036/viewer/2022062323/56816050550346895dcf7a04/html5/thumbnails/6.jpg)
Experiment 1
(1) Concept explanations and Condensed civil code
(2) Concept explanations
(complete civil code)
(3) Condensed civil code (4) No support‘learning by doing’
(complete civil code)

Results reasoning on test
• Support by condensed civil code during training leads to sig. better performance on the reasoning test than students not supported with the condensed civil code
• No interaction effects • No effects on mental effort• Higher efficiency
• Lot of room for improvement…!

Experiment 2
• 75 first-year students & 36 third-year students
• Pre-test• 2 Training cases• 1 Test case• Complete civil code• Mental effort

Results experiment 2
• Support by worked examples during the training phase leads to significant better results on reasoning during the test
• Applies for both, first-year and third-year students! No expertise reversal effect!

Mental effort• Students who studied worked examples reported
less mental effort (during learning) than students who solved the case with no support or problem steps
• No differences on mental effort reported on the test, but....
• Studying examples leads to higher performance

Practical / Theoretical implications
• Support by worked examples improves learning • Higher efficiency • No expertise reversal effect; probably due to the
domain complexity
