Challenges of using mother tongue to teach in schools ?

1. Lack of resources: Many schools may not have adequate resources, such as textbooks and teaching materials, in the mother tongue. This can make it difficult for teachers to effectively teach in the students' native language.

2. Limited teacher proficiency: Teachers may not be proficient in the mother tongue, especially if they were educated in a different language. This can lead to difficulties in effectively conveying complex concepts and ideas to students.

3. Standardized testing: Many standardized tests are administered in a different language, which can create a disconnect between what students are learning in their mother tongue and what is being assessed on exams.

4. Social stigma: In some communities, there may be a stigma associated with speaking the mother tongue, leading students to feel embarrassed or ashamed of their language and culture. This can impact their motivation to learn and engage in the classroom.

5. Limited opportunities for higher education and employment: In some cases, students who are educated in their mother tongue may face limited opportunities for higher education and employment, as many universities and workplaces require proficiency in a different language.

6. Lack of recognition and support: Mother tongue education may not be recognized or supported by government policies and funding, leading to a lack of resources and infrastructure for schools to effectively implement this approach.
