• Statistics and Math are often seen as talents, not skills– Students should practice sufficiently
• Students often only practice the topic of that week– Students should retrieve and rehearse previous topics
• Students who are behind are ‘lost’– Students should work at their own level
• Students enter programs with varied backgrounds– Students should be able to discover their hiatusus
Problems with Teaching Statistics
15-04-2023 4
Adaptive• Self-organizing adaptive
algorithm based on Elo’s chess algorithm
• Students and problems are both ‘players’. The player that wins from a higher rated player will go up a bit in rating, and the losing player down.
Adaptive Training and Tracking Game
15-04-2023 5
Adaptive• 75% chance of correct• High Speed High Stakes scoring
rule• Both speed and accuracy count
So• Guessing fast is costly• Speed visible through coins in the
game
Adaptive Training and Tracking Game
15-04-2023 6
Training• ~2,000 Statistics problems in three domains
Descriptive Statistics, Probability and Inferential StatisticsCurrently only in Dutch, UK items have been translated
• Always train on your own level: 75% chance of corrector 60% or 90%, if you choose a different difficulty
• Web based
Adaptive Training and Tracking Game

Tracking, see statistiekfabriek.com • See your development and training frequency
Insight in your progress
• Compare with peers• Find your problems
Adaptive Training and Tracking Game
15-04-2023 9
Game• Pimp your factory with coins• Speed is important for adaptive algorithm• A faster response risks
more coins• Improve your factory
with coins earned

• Mandatory Statistics course Research Methods and Statistics
• 496 1st year students of Psychology• 89% used the Stats Plant• Bonus point used as incentive • One in three students used game dynamics
(i.e. pimped their factories)• Students enthusiastic
Implementation and Use

Paradox of formative testing• Students overwhelmingly indicate they want
more formative tests (source: student survey Digital Natives onder de Loep, goo.gl/1GShCF)
• Without incentive, students don’t (effectively) use formative tests
• With incentive, most students play minimum requirements
• With incentive, risk of other undesirable effects
Implementation and Use
15-04-2023 12
• Playing frequency and final mark r=.31• Stats Plant rating and final mark r=.39• Regression analysis:
only rating predicts final mark
• Success rate Research Methods & Statistics from worst to highest
Effects
