Final answer:
Johnson's inspiration to become a teacher stemmed from his formative experiences with education, his understanding of its societal impact, as well as his personal connections with the community. He recognized the role of education in alleviating social problems and pursued opportunities to expand his influence and impact through teaching and research.
Step-by-step explanation:
Johnson chose to become a teacher following his college graduation for several reasons. One compelling reason was his early educational experiences, as indicated by his statement about the profound impact learning to read had on him as a first grader, inspiring him to share his experiences with future generations. Moreover, Johnson recognized that education was a powerful tool in addressing social problems, which is reflected in his support for the Education Act, providing increased federal funding to schools, and creating programs for disadvantaged children. This act was part of the Great Society vision, which placed education reform as a critical pillar. Johnson's commitment to improving the education system, as a means to combat poverty and instigate social change, demonstrated his understanding of the transformative power of education.
Another insight into his decision can be gleaned from his teaching stint where he would stay with the families of the students he taught, indicating his investment and close connections with the community. Johnson's later career moves, such as teaching the geography curriculum and doing research on the West Coast, show that he pursued opportunities that would allow him to have a greater impact through education and research. His desire to teach and improve the lives of others, particularly the impoverished, was likely a strong driving force behind his decision to enter the teaching profession.
