Abstract: As learning paradigms evolve and schools undergo modernization, the role of teachers will inevitably be redefined. This study examines how teachers enact three core modernity attributes across professional dimensions: 1) As agents of professional development: cultivating individual competencies through autonomous practice; 2) As instructional practitioners: driving pedagogical innovation through creative engagement; 3) As institutional change catalysts: expanding organizational value influence through strategic openness. The cultivation of teachers' modern qualities requires clear value orientations to guide evaluation directions. Following a developmental orientation, schools strengthen diagnostic evaluations to foster teachers' autonomy. Adhering to a scientific orientation, schools optimize formative evaluations to stimulate teachers' innovation. Moving toward a collaborative orientation, schools improve summative evaluations to enhance teachers' openness. Focusing on key indicators in teacher evaluation can prevent evaluation from losing focus and enhance evaluation effectiveness. By setting evaluation key indicators based on teachers' roles in educational activities, evaluation can promote the cultivation of teachers' modern qualities and drive schools and teachers toward high-quality development together.
