In preparing his evidence of work, what is Juan primarily working on?

Juan is primarily working on a professional portfolio, which serves as a comprehensive collection of his work and achievements as an educator. A professional portfolio enables educators to showcase their teaching philosophy, lesson plans, student projects, assessments, and reflections on their practice. It provides evidence of their competencies, growth, and effectiveness in their field.

This portfolio may be used for various purposes, such as job applications, promotions, or assessments of teaching quality. It highlights not only the educator's skills and experiences but also their commitment to continuous development and reflection, essential aspects of professional practice in education. While other options might relate to aspects of teaching or assessment, the focus on compiling a professional portfolio directly aligns with Juan's effort to present his work comprehensively and effectively.
