Collaboration in teaching about science teaching plays a vital role in enhancing both teacher professional development and student learning outcomes. Collaborative practices encourage educators to share knowledge, teaching strategies, and reflective insights that promote innovative approaches to science instruction. Through teamwork, co-planning, peer observation, and joint problem-solving, teachers create a supportive environment that fosters creativity, critical thinking, and deeper understanding of scientific concepts. This process not only strengthens pedagogical skills but also builds a sense of community and shared responsibility among educators. Furthermore, collaboration enables the integration of interdisciplinary perspectives, the effective use of technology, and the design of engaging, inquiry-based learning experiences. Ultimately, collaborative teaching contributes to developing students’ curiosity, scientific literacy, and problem-solving abilities, while ensuring continuous improvement in teaching practices.
