Final answer:
Challenging problems for students' levels satisfy the motivation learning factor, fostering engagement and intrinsic motivation through achievable yet stimulating tasks.
Step-by-step explanation:
Giving students challenging problems for their level satisfies the motivation learning factor. This approach aligns with educational theories that suggest students experience intrinsic motivation when they are provided with tasks that are challenging yet achievable. When instructors design assignments targeted at students' levels, they allow for greater engagement and foster personal investment in the learning process. Practice, homework, and real-world applications contribute to creating a dynamic and motivating learning environment that encourages students to deepen their understanding and mastery of the subject matter.
