About This Topic
Career Aspirations focuses on the professional goals of students and the skills required for the 21st-century workforce. For 9th graders, this topic is a bridge between their current studies and their future lives. Students discuss which careers are considered prestigious in different cultures and how societal needs dictate these priorities. This aligns with ACTFL standards for interpersonal communication and lifelong learning.
This unit also explores how learning a second language can expand a student's future career options in a globalized economy. Students learn to discuss their own goals and the skills they will need to achieve them. This topic comes alive when students can physically model the job interview process or collaborate on a 'future career' project, making the language a practical tool for their own success.
