As per constructivist approaches of learning, learning is facilitated when :

The correct answer is Activities are interactive and collaborative.

Explanation:

Constructivism is a key theory in educational psychology which posits that learners actively construct their own knowledge and understanding of the world, rather than passively receiving information from the teacher.

Key principles of constructivist approaches include:

1. Active Engagement: Learning happens best when learners actively engage with the content through hands-on activities, discussions, and problem-solving.
2. Social Interaction & Collaboration: According to social constructivists (such as Lev Vygotsky), knowledge is co-constructed through interaction with peers, teachers, and the environment. Collaborative group work and interactive activities enable students to share perspectives and build deeper understanding.
3. Meaningful & Connected Content: Constructivist learning connects new ideas to learners' existing knowledge structures and cultural context.

Let's analyze the given options:

• Activities are interactive and collaborative: Correct. Interactivity and peer collaboration are fundamental constructivist strategies that foster active learning and deep conceptual understanding.
• Content is disconnected and eccentric: Incorrect. Disconnected content hinders meaningful learning and active construction of schema.
• Pedagogy is teacher-centric and culturally indifferent: Incorrect. Constructivism favors learner-centric, culturally responsive pedagogy where the teacher acts as a facilitator.
• Tasks are incoherent and disorderly: Incorrect. Tasks should be structured, coherent, and scaffolded to guide meaningful inquiry and discovery.
