The challenge of competency-based education to teachers' professional competencies lies in teachers’lack of experience in unit design and instruction based oncurriculum standards. This study aims to explore the impact of design and instruction of a novel unit designed based on the '' System of Standards-Based Curriculum Design'' (referred to as S2) in a 10th-grade class on the development of teachers' professional competencies. The data collected in this study includes the participating teacher’s novel unit plan, teaching reflections, teaching materials, and interviews. Data analysis was conducted using a constant comparative method. The results of the study indicate that the unit design and instruction based on S2 positively influenced the development of the teacher's professional competencies in the following ways: (1) the teacher has clarified the content knowledge, thereby enhancing her professional ability and confidence, (2) the teacher has acquired the knowledge and skills of unit design, and (3) the experience has fostered the teacher’s values and attitudes towards unit design and instruction. According to the Guidelines for Teachers' Professional Competencies—Standards for Pre-service Teacher Education and Curriculum, further discussion reveals that S2 teachers have achieved substantially positive development in areas, including understanding educational development concepts and practices, recognizing and respecting learners’developmental and learning needs, planning appropriate curriculum, instruction, and diverse assessments, creating a positive learning environment with tailored guidance, and identifying with and practicing professional ethics in teaching. |
