Abstract
The aim of this paper is to present the
result of a research which analyzed the CLIL
approach incidence in the scientific thinking
development through the Natural Science sub-
ject in fourth grade students at Colegio Bilin-
güe Hispano Americano in Colombia. To achie-
ve this, a comparison was made between the
groups 4th B, in which the approach was applied,
and 4thA which continued receiving the conven-
tional classes. A diagnostic test was carried out
in both groups in order to measure their scien-
tific thinking level, and then a didactic unit was
designed and applied accordingly to the CLIL
approach characteristics. An intermediate test
was applied in the middle of the implementa-
tion, but only in the focal group, to observe the
students' advance, and finally a third test was
carried out to know if there was any progress in
the development of scientific thinking in both
groups. The results from this last test showed a
marked improvement in the focal group, there-
fore, it is relevant to affirm the positive influen-
ce of the above mentioned approach in the deve-
lopment of the scientific thinking.
