In the United States there is a chronic shortage of qualified physics teachers. To fill the gap, many schools have placed teachers without a specific degree or certification in physics classrooms. To support them, an intensive three‑year professional development (PD) program was launched, aimed at these out‑of‑field teachers.
The study examined how personal disposition—attitude, motivation, and confidence—affected outcomes. Teachers who were enthusiastic about the PD showed significant gains in physics content knowledge, adopted more student‑centered methods, and reported higher self‑efficacy. Those less engaged made more modest progress.
These findings indicate that offering training alone is not enough; it is essential to create learning environments that spark curiosity, reflection, and confidence. Including discussion sessions, constructive feedback, and emotional support can turn a simple course into a truly transformative experience. Future PD designers should treat “disposition” as a key factor, making interventions more effective and ultimately improving students’ physics learning.
