In support of the implementation of national security education in the junior secondary English Language classroom, the Curriculum Development Institute has developed three sets of presentation slides to provide suggested learning and teaching materials and activities for exploring different domains of national security such as cultural security, science and technology security and outer space security in the English lessons. Schools are encouraged to make use of the resource materials to enrich students’ English learning experiences and enhance their understanding of our country and national security. While the resource materials are intended for use in the junior secondary English Language classroom, schools are advised to adapt the materials with reference to their students’ needs and abilities to cater for learner diversity.
