Constructivism Learning Theory

Last week the topic we have covered is ''Constructivism'', one of the learning approaches. After doing a little research, I have found some basic assumptions and features of the constructivism learning theory which completely correspond with the class experiment. In the experiment. In the classroom activity, we were asked to search in the given topic by means of the web and then take note to highlight the key points and summary the topic, lastly we made a short presentation to explain our topics to each other. These activities reflect two of the key concepts of constructivism learning theory :
Assimilation; to learn by assimilating new idea to the experienced one.
Accomodation; to learn by constructing new structure and by reframing the expectations with the outcomes.
The other basic principles of the theory are : knowledge is consrtucted by learner, social learning is prefered, students are actively engaged in learning process-physically,mentally,verbally, motivation is a key component in learning, the more we know-the more we can learn and learning is contextual.
I have never experienced in this learning theory. When I was in highschool, traditional method is often used in  teaching process. Constructivism learning theory is very different approach toward traditional learning. Instead of telling, the teacher should begin asking, instead of answering questions, the teacher in this case must make the student comes to the conclusion on their own.
I have attached a video, which explains the theory in an effective manner,  I am sure you will enjoy.
