To promote meaningful learning in the classrooms, a teacher should –
(i) help students to regulate their own emotions and motivation.
(ii) categorize and label students according to their performance and make ability-grouping.
(iii) promote dialogue and discussion among children to build multiple perspectives.
(iv) ignore diversity in the classroom and follow standard methods of instruction.

The correct answer is (i), (iii).

To promote meaningful learning in the classroom, a teacher should adopt child-centered, inclusive, and emotionally supportive pedagogical practices.

Analysis of the statements:

(i) Help students to regulate their own emotions and motivation: This is correct. Emotional self-regulation and self-motivation are essential components of self-directed and meaningful learning. When students learn to manage their emotions, they become more resilient, engaged, and independent learners.

(ii) Categorize and label students according to their performance and make ability-grouping: This is incorrect. Labeling and fixed ability-grouping create negative self-fulfilling prophecies, lower self-esteem in low-performing students, and promote a fixed mindset rather than a growth mindset.

(iii) Promote dialogue and discussion among children to build multiple perspectives: This is correct. Encouraging dialogue, peer interaction, and discussion supports social constructivist learning (as advocated by Vygotsky). It helps students construct deeper understanding by considering diverse viewpoints.

(iv) Ignore diversity in the classroom and follow standard methods of instruction: This is incorrect. Effective teachers acknowledge and celebrate classroom diversity by adopting flexible, differentiated instruction tailored to varied learning needs and backgrounds rather than enforcing rigid standard methods.

Therefore, statements (i) and (iii) are effective strategies to promote meaningful learning.
