NBCT Joanna Murray (AYA Social Studies) served as the keynote speaker at the Beginning Teacher Support and Assessment (BTSA) Colloquium for Vista Unified School District in California this week.  The colloquium, which serves as an end-of-year event for district teachers who are clearing their teaching credentials through the district induction program.  Murray shared the importance of purpose in her address.  "My theme was purposefulness," explained Murray.  "I was trying to encourage these new teachers to make themselves marketable in these tough times by remaining as well-educated as possible.  I also wanted to ensure they think about giving back by thoughtfully supporting future new teachers coming into the profession."  Murray advised the candidates to continue challenging themselves by considering masters programs or National Board Certification to address this purposefulness in their professional development.
