In their response about learning methods, which technique did the individual mention as part of their study habits?

The mention of flashcards as part of the individual's study habits highlights an effective technique for promoting active recall, which is a fundamental principle of effective learning. Flashcards facilitate the process of retrieving information from memory, reinforcing knowledge, and improving retention. This method allows for spaced repetition, where users can revisit and test themselves on concepts over time, ultimately enhancing recall ability.

In contrast, while group study sessions, online courses, and listening to lectures can also be beneficial, they may not engage the learner as actively as using flashcards. Group study sessions could lead to distraction, online courses might lack personal interaction or engagement, and listening to lectures, although informative, often requires supplementary active learning techniques like flashcards to reinforce understanding. Thus, the effective use of flashcards stands out as a strategic approach to studying, emphasizing the importance of personal engagement in the learning process.
