Experiencing new teaching methods is one of the primary goals of school, in order to improve the
effectiveness of learning. A psychological theory, the so-called constructivism, claims that people
gain knowledge of the world by experiencing things and reflecting on those experiences. The
American psychologist Jerome Bruner was one of the first experts who spread this idea. He thought
that the aim of education had to be to create autonomous learners. Thus, teachers should help
students to actively construct knowledge rather than presenting a series of facts as it would usually
happen in a traditional classroom, where students receive information only in a passive way; the
students work individually, they listen to and memorise lessons, and use textbooks and teachers to
learn, they all do the same thing and their desks are organised in rows. This is a teacher-centred
method in which teachers play the most important role; indeed, they are experts who produce facts.
On the contrary, the constructivist method focuses on students, who collaborate and do practical
experiments using previous knowledge to formulate hypotheses and draw conclusions. In addition,
they do different tasks and work together in groups or circles. In this case the traditional teacher
turns into a coach who guides the students to discover facts and listens to their discussions.
Nowadays there are different techniques based on constructivism. Flipped classrooms and the
Jigsaw method are two of the most popular examples which put this theory into practice.
Flipped classrooms
The flipped classroom methodology completely reverses traditional teaching ideas. Students learn at
home via on-line videos which can be paused and studied as often as necessary. On the other hand,
school becomes the place where they can do homework and other group activities such as project
work or laboratory experiments. In this way teachers spend more time interacting directly with
students, improving outcomes.
Jigsaw method
This cooperative learning technique allows students to work in small groups which depend on each
other. At the beginning, groups are divided and every single member studies and researches a
particular aspect of the task. Therefore, all the students become experts on a certain aspect of the
project and when they return to their original group, they are able to report their findings to the
other members. Finally, they can put the information together in order to show a complete work to
the other groups, which have to judge and define the best project.
