4. Pain Points
Following are some of the Pain Points for the ‘Children’ user segment,
Children often have short attention spans, making it challenging to keep them engaged in language-learning activities for extended periods.
Language learning may not always be perceived as fun or engaging by children, leading to a lack of motivation and interest in participating in language lessons.
Children may struggle with pronouncing unfamiliar sounds and words in a new language, which can affect their confidence and ability to communicate effectively.
Building a diverse vocabulary in a new language can be daunting for children, particularly when faced with unfamiliar words and concepts.
Understanding grammatical rules and sentence structure in a new language can be challenging for children, leading to errors in speaking and writing.
Children may have limited exposure to the target language outside of the classroom, which can hinder their language acquisition and proficiency development.
Children may feel self-conscious or embarrassed about making mistakes while learning a new language, leading to reluctance to participate in language activities.
Learning a new language often involves exposure to different cultural norms, customs, and traditions, which can be confusing or unfamiliar to children.
One-size-fits-all language learning approaches may not effectively cater to individual children's learning styles, preferences, and pace of learning.
Children may lack access to personalized feedback and guidance from teachers or tutors, hindering their ability to address areas of weakness and improve their language skills effectively.
