Which feature encourages collaboration during training in Cornerstone?

The option highlighting social learning features is the one that promotes collaboration during training in Cornerstone. Social learning features facilitate interaction among learners, enabling them to share knowledge, discuss concepts, and engage in collaborative activities. This can include features like forums, group assignments, and peer feedback mechanisms, all of which enhance the learning experience by encouraging participants to learn from each other.

In contrast, individual assessments focus on measuring personal knowledge and skills without the element of collaboration, while mandatory training sessions enforce compliance rather than interaction. Standardized testing also emphasizes individual performance over group engagement and does not inherently foster collaborative learning. Thus, social learning features stand out as the key component for creating a collaborative training environment.
