Researchers have developed new methods for analyzing learning progress in digital environments, particularly when the skills measured by assessment items are not fully known. They propose two approaches: a joint analysis that estimates skills and learning simultaneously, and a stepwise analysis that first establishes the skill structure before studying learning. The study found that these different approaches can lead to divergent conclusions about how learners master skills over time, impacting how educational progress is reported. The research provides R code for implementing both analyses and suggests that joint analysis is more reliable when the item-skill structure is uncertain. AI
