A- in my opinion, teachers’ beliefs have a strong impact on their teaching practices. I think the way a teacher views learning affects how they design lessons, interact with students, and assess their progress. For example, if a teacher believes that learning happens through active participation, they are more likely to use communicative and student-centered methods.
b- i don’t think the learner-centeredness paradigm is static. In my view, it keeps changing with new research, technologies, and students’ needs. What we consider “learner-centered” today might not be the same in the future, because our understanding of learners and learning keeps evolving.
