Common Core State Standards
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.
Active Learning Ideas
Simulation Game: The Global Job Interview
In pairs, one student acts as a hiring manager for an international company and the other as a job applicant. They must use the target language to discuss skills, experience, and career goals, focusing on professional etiquette.
Inquiry Circle: Careers of the Future
Groups research which careers are in high demand in a specific target-language country. They create a 'career guide' for their peers, highlighting the skills and education needed for these roles.
Think-Pair-Share: Why Learn a Language?
Students discuss how knowing a second language could help them in their dream career. They then share their ideas with a partner, using the target language to explain the specific benefits they see.
Watch Out for These Misconceptions
Common MisconceptionYou only need a second language if you want to be a translator.
What to Teach Instead
Language skills are valuable in almost every field, from medicine to engineering to business. Using the 'Why Learn a Language?' activity helps students see the practical and professional benefits of bilingualism in a global market.
Common MisconceptionThe 'best' jobs are the same everywhere.
