What type of subject matter should be there in an educational application?

In educational applications, the subject matter should be organized from simple to complex to support effective learning.Key Points

• Simple to complex is a fundamental instructional principle in pedagogy.
• It ensures learners build foundational understanding before tackling more difficult or abstract content.
• Starting simple reduces cognitive load and builds confidence.
• It aligns with developmental and psychological readiness of learners.

Hint

• Without any objective: Lacks direction and purpose; not effective for structured learning.
• Complex to simple: Overwhelming for learners, especially beginners.
• Time consuming to learn: Efficiency is key in learning apps; content should be concise and well-sequenced.

Hence, the subject matter should follow a simple to complex progression for better understanding and retention.
