Therefore, it is required that teachers should be able to plan and create active learning environments such as CL;
and encourage students to acquire and construct knowledge through their study and bonding with their daily life.
This educational research helped to identify strengths and challenges of implementing the CL based on the UPP
educative model to establish meaningful scenarios in teaching chemistry model. Students and teachers identified the
usefulness of this alternative methodology to promote chemistry subjects of positive interdependence. An aspect that
emerges when all group members are aware they cannot succeed unless their classmates are able to reach it too. If
they consider the effort made by each student, benefits himself and the others, (Johnson,1994:34).
Positive interdependence allowed that the interchange and coordination of activities move groups to generate
critical and controversial issues that help to understand the subjects better and bring on to improve student learning
and facilitate the connection between scientific and everyday thought.
