Concept:
A student-centered classroom is a teaching approach in which students actively participate in the learning process. The teacher acts as a facilitator rather than the sole source of knowledge.
• Encourages active learning.
• Promotes discussion, collaboration and problem-solving.
• Develops critical thinking and creativity.
Step 1: Understand student-centered learning.
In a student-centered classroom:
\[
\boxed{\text{Students actively participate in learning activities.}}
\]
They ask questions, discuss ideas, solve problems and work collaboratively.
Step 2: Identify the role of the teacher.
The teacher:
• Guides students.
• Facilitates learning.
• Encourages participation instead of only delivering lectures.
Thus, learning becomes interactive rather than teacher-dominated.
Step 3: Compare the options.
• Active participation of students -- Correct.
• Passive participation of the teacher -- Incorrect concept.
• Focus on the exam only -- Not student-centered learning.
• Rote learning of students -- Opposite of student-centered education.
Step 4: Final conclusion.
Hence, the correct answer is:
\[
\boxed{\text{Active participation of students}}
\]
