Which of the means that the subject matter in the curriculum is within the range of the experiences of the learners as well as the contents are organized and sequenced to facilitate learning?

The concept you're referring to is known as "Developmental Appropriateness." This principle is based on the understanding that learning experiences must be suited to the learner's level of understanding and abilities, taking into account their developmental stage.

Here are the steps to understand this concept:

1. Identify Learner's Level: The first step is to understand the learner's current level of knowledge, skills, and experiences. This can be done through assessments, observations, and discussions.

2. Match Content with Learner's Level: The next step is to ensure that the subject matter in the curriculum is within the range of the learner's experiences. This means that the content should be relevant and meaningful to the learner, and not too advanced or too simple for their level.

3. Organize and Sequence Content: The content should be organized and sequenced in a way that facilitates learning. This means starting with simpler concepts and gradually moving to more complex ones, building on what the learner already knows and can do.

4. Facilitate Learning: The final step is to provide support and guidance to help the learner understand and apply the content. This can involve a variety of teaching strategies, including direct instruction, guided practice, independent practice, and feedback.

In summary, developmental appropriateness means that the curriculum should be tailored to the learner's developmental stage and experiences, and organized in a way that supports their learning process.
