In day to day life, different people observing the same event but report it differently because of the different world view. Which type of constructivism is this?

Constructivism is a learning theory that emphasizes how individuals actively construct knowledge based on their experiences and interactions. 

Key Points

• When people observe the same event but interpret and report it differently due to their individual worldviews, beliefs, and prior experiences, it reflects radical constructivism.
• This perspective holds that knowledge is not a direct reflection of reality but is personally constructed by each individual.
• Radical constructivism suggests that there is no single objective reality experienced identically by all; instead, each person's understanding is subjective and shaped by their unique background, context, and mental framework. 

Hint

• Cultural constructivism emphasizes the role of culture in shaping how individuals learn and understand the world, but it is more collective than individually subjective.
• Cognitive constructivism, associated with Piaget, focuses on how individuals build knowledge through mental processes, but it emphasizes developmental stages rather than worldview differences.
• Social constructivism, influenced by Vygotsky, highlights the importance of social interaction and language in the learning process, emphasizing shared knowledge construction.

Hence, the correct answer is radical constructivism.
