Technology and engineering functional literacy should be intentionally developed in the school system -- like any other competence, it does not develop spontaneously. For this purpose, a didactic model, the Metacognitive model for developing technology and engineering literacy (McM_T&E), was developed, implemented and evaluated. The results of evaluation show that focusing on technology and engineering literacy in Technology and Engineering classes using the McM_T&E model increases students' technology and engineering functional literacy.
