Which law is concerned with the necessity for learners to be ready and receptive to instruction?

The concept of readiness is essential in the learning process, and the Law of Readiness specifically addresses this by emphasizing that learners must be prepared and willing to receive instruction in order to effectively engage with new information or skills. When learners feel ready, they are more likely to be attentive, retain information, and apply what they have learned. This law suggests that instruction will be most effective when it aligns with the student's current levels of motivation, interest, and mental preparation.

In contrast, the other options, while related to various aspects of learning, do not specifically target the necessity for learners to be ready and open to instruction. The Law of Exercise pertains to the idea that practice reinforces learning, and the Law of Equity involves fairness in treatment and opportunities in educational settings. The Law of Motivation emphasizes the drive or desire to learn but does not solely focus on the readiness aspect. Thus, the Law of Readiness is fundamentally about the learner's preparedness, making it the correct choice in this context.
