Summary A blended-learning approach in the context of education at distance, with a primary objective of seeking the advantage of a b-learning approach in a didactic interactive multimedia environment.

Exploration of the validity of the Boyle-Mariotte law (PV = const) in secondary Portuguese education.

Introduction We live in a generation of distance teaching and learning, which has gained and increasing importance due to the need of growing education and training levels in a qualitative and quantitative way.

b-learning is an interesting resource, as enables each individual to choose the learning route that best suits for him.

Introduction With b-learning students have a new learning opportunity (online and face-to-face), where they can choose or combine the offerings of courses according to their needs.

b-learning is a derivative of e-learning.

e-lab has proven to be an important tool in stimulating students to scientific subjects.

Discussion This platform is a real remotely controlled laboratory .

The e-lab is a platform for science education freely available which is currently at http://www.e-escola.pt/elab.asp.

Discussion

Discussion The experimental verification of Boyle-Mariotte law is well suited to the seventh and eighth year curricula in the Physics and Chemistry subject (primary education), as well as in the twelfth year of Portuguese school in the Chemistry classes (secondary education).

It is also possible to determine the ideal gas constant (R).

Results in the classroom

Strategy used:

Groups of two students with a computer and Internet connection;

Students performed some tests inside and outside the classroom;

Evaluation of the results in a report according to a script created for this purpose, in addition to a quiz with pre- and post-lab questions.

Conclusion The platform itself has the resources for the preparation, operation and implementation of various experiences and is an asset for teachers to work with students scientific skills.

The results obtained until now point that e-lab platform is a good blended-learning tool for the teaching of Physics and Chemistry that sparked interest and motivated students by the easiness with which experiments can be made.
