1. Language of instruction in early school years should be the language of the school's catchment area for smooth transition from home to school hence all teachers in pre-schools should be from local area and must teach English as a subject just like any other. Produce learning materials in the local language for different parts of the country. English should become a language of instruction in middle level/upper primary classes (preferably from Grade 4 where it is assumed that the children can by now understand and communicate in the English language as they continue to master it).

2. Parents, be proud of your first/native language, teach your children and let them master it before you introduce them to any other languages (official or national language- great challenge in cosmopolitan urban centres/towns). This creates a sense of belonging and a child identifies with his roots and will be ready to learn new things once out of the nest. I must admit this is practically challenging. 

3. If the children cannot learn in a language that you are using to teach them, then you must teach them in a language that they understand so that they can learn. Otherwise you are wasting your time and energy and will never realize the desired learning outcomes. 

Policy makers

they need to ensure that the lower classes should use the local language and adapt the curriculum to accommodate such. the main reason would be for maximum learning opportunities for the learners

teachers

encourage teaching in local language in lower classes or at least in a common language of the learners. this would ensure learners have lots of knowledge and skills gained. use the second language as a subject only if offered in lower classes

parents

they need to be proud of learners achievements and support their learners to learn in the local language. this would help learners to be interested in school

This may be challenging to implement in my country as we are predominantly english speaking.  In recent times we have incurred an influx of spanish speaking immigrants from a nearby country fleeing due to political unrest and instability.  We now have a lot of spanish speaking people in our communities with a lot of language barriers

1. Policy makers can mandate a bilingual signage of major areas such as street signs government offices entrances/ exits directions  in the malls groceries and even subtitles during news broadcasts

2. parents should expose children to both languages from early for early transition and learning of the languages

3. spanish should be an additional  requirement for teaching and not just an asset.  If not applicable and accessible training should be made available for teachers to learn it, practice it and teachwith it
