Shilpa wants her students to learn about manufacture of sugar through the educational tour approach. What is essentially her role in this? 

An educational tour is a planned activity where students learn through direct experience outside the classroom. The teacher's role in such an approach goes beyond logistics; it includes ensuring that learning objectives are clear and connected to the curriculum.Key Points

• In this case, Shilpa’s essential role is to brief students about the purpose and expectations of the tour.
• This helps students understand why they are visiting the sugar manufacturing unit and what they should observe, learn, and reflect upon.
• It prepares them to engage meaningfully with the experience and connect it to classroom learning.

Hint

• Organising the tour, informing parents, and accompanying students are important administrative and safety-related tasks, but they are supportive, not central, to the learning objective of the tour.

Hence, the correct answer is briefing the students about the purpose and expectations from the tour.
