Table 10 Summary of smart content usage across different clusters when system usage is split into two parts: usage during course lectures, namely regular practice, and usage during exam preparation

From: An integrated practice system for learning programming in Python: design and evaluation

  1. |P1|, |P2|, |E1|, and |E2| indicate the number of semantic problems, Parson problems, annotated examples, and animated examples, respectively
  2. Usage is expressed as mean and standard error for the mean (in parentheses)
