According to John Salvia and James Ysseldyke, what is primarily affected by experiential background?

Experiential background plays a critical role in influencing a student's acculturation process, which refers to how individuals adapt to and adopt the cultural norms of a different cultural milieu. Salvia and Ysseldyke highlight that students' prior experiences, including their cultural background and experiences with language, customs, and social norms, can significantly shape their ability to integrate into a new culture and educational system. This adjustment is crucial for educational success, as it can affect how students interact within a classroom and relate to peers and teachers.

In contrast, while academic achievement, peer relationships, and socioeconomic status are certainly impacted by various factors, they are more directly influenced by a broader range of elements including instructional quality, availability of resources, and individual characteristics rather than purely by experiential background alone. Acculturation specifically reflects the process of adapting to cultural changes, making it the most relevant choice in this context.
