Social constructivism holds that knowledge is constructed through social interaction and negotiation with others. In a social constructivist classroom, the focus shifts from the teacher to the students, who are actively involved in their own learning process rather than passively receiving knowledge from the teacher. Instruction moves from whole-class lectures to small group work, with the teacher facilitating learning rather than lecturing. Students engage with each other and learn to work together to build knowledge. Implementation strategies include shifting students beyond their current understanding through support and scaffolding, using tools like Bubble Us for brainstorming and online collaborative spaces like wikis for sharing and extending ideas.
