This report shows the design and implementation of a New Teaching Approach (NTA) for
chemical bonding to 1st year high school students (16-18y). To design and test the proposal
several key aspect regarding chemical bonding have been determined after taking into
consideration the student preconceptions. The NTA has been implemented in one
experimental group while the control one has been taught with traditional methodology. The
same comprehensive test has been offered to both groups after being taught chemical bonding,
and the answers have been analysed. In the findings it is observed that the proposed NTA and
the used teaching strategies let students develop a higher thinking analysis and a deeper
knowledge of chemical bonding, although still some aspects regarding the role of energy in bond
formation should be improved in NTA
