This book deals with aspects of language skills (reading and writing) in primary and secondary school pupils in Mozambique. It addresses various problems and difficulties presented by some students in the Teaching and Learning Process (PEA). It presents various concepts linked to language skills, in particular oral and written production in Portuguese language teaching. In view of the current teaching situation, the possibilities for the active participation of teachers, parents and carers, pupils and secondary school management in resolving these difficulties are presented. And, pedagogically, some strategies and methodologies are presented that aim to overcome reading and writing difficulties in pupils who have left primary school without having developed the basic language skills of reading and writing. The departments responsible for education and teaching are recommended to follow some lines of action in order to monitor students' learning throughout their school career.
