Which term encompasses all sources that contribute to a student’s learning, including teachers and textbooks?

The term that best encompasses all sources that contribute to a student's learning, including teachers and textbooks, is the concept of a learning environment. This term refers to not just the physical space in which learning occurs but also includes the social, emotional, and psychological factors that can impact learning. It captures the interactions that students have with various elements, such as their teachers, instructional materials, peers, and the overall educational context.

Curriculum specifically refers to the content and topics that are taught within an educational program, while instruction pertains to the methods and strategies that educators employ to facilitate learning. Pedagogy is closely related to instruction, focusing more on the theory and practice of teaching itself. While instruction and pedagogy certainly play a crucial role in the learning process, the learning environment provides a broader framework that encompasses all these elements. Therefore, the correct term that reflects all sources contributing to a student's learning is the learning environment.
