Dear Khaled

The PBL (project based learning)  and flipped classroom are one of the interesting and leading methods in many educational institutes.In our college we recently applied with our students the flipped classroom  , in the frame of the pedagogic instruction in schools. that was interesting.

in the flipped class room a typical lesson that happens in the classroom occurs at home. Students watch lessons or suitable material on video at home, and then return to school to engage in the exercises they would traditionally have for homework, and to ask questions based on the lesson or material  they watched on their own at home.

those aren't the only ones.

Try to gamify your teaching and it will work wonder.
