Given the fact that constructionism and constructivism are theoretical frameworks, does the pedagogical model of problem based learning more closely align with the constructivist approach as opposed to the constructionist approach.
Of course, problem-based learning is a Constructivist (not constructionist) pedagogy in which students are learning and developping thinking skills by solving individually some real problems. (please see this related paper: https://www.cc.gatech.edu/faculty/ashwin/papers/er-05-03.pdf)
Others say that project-based learning is a constructionist pedagogy because of the social interactions with other partners of the work group.
Both constructivism and constructionism seem to claim to be theoretical homes for problem-based learning. Constructivism is, as I interpret it, more concentrated on the understanding and knowledge that a problem-solving process gives to the individual or to the group. Constructionism seems more targeted at the making of the solution and the product itself as a product brought into being of learners as creators, individually or in groups. Something is being understood just by the making of it - it can be constructed and deconstructed and modified and explained. I would also say that constructionism is more skills-related (being able to do something, by understanding it) and close to trial-and-error and discovery. Constructivism is more hermeneutic, targeted at understanding and individual/social reconstruction of established knowledge. Both are contrasted against the background of knowledge as a product of transmission of knowledge.
Is problem-based learning the same as project-based learning in your mind? I'm doing a deep dive into the early writings of Papert and Harel and one key quality of constructionism is the making of a meaningful, tangible product.
The background in computer-based learning found in constructionism would also seem to indicate that producing a software application is also a tangible product in this sense.
Constructivism is a theory describing how learning regardless of whether learners are using their experiences to understand a lecture, it build critical thinking and PBL is a learning environment that embodies most of the principle that improve learning active, cooperative, getting feedback, tailored to student learning and to solve problems, both increase critical thinking in learning.
