這波九年一貫課程改革的浪潮裡，明裡是藉由課程的改革滿足杜會對教育改革的 殷切期盼，實則帶動教學與評量的同步改革，進而對教育產生全面性的質變與量雙，課程、 教學、評量三者實是相互牽動，合為一體的。如此一來，實務工作者不禁要問：有何教學方 式可以協助教師落實九年一貫課程，又能兼顧評量上的需求？在話多可行選項裡，筆者以為 專題學習(project-based larning)不失為一優良選擇，因為專題學習不僅在概念上與這波 課程改革理念相謀合，更是一種集課程、教學、評量三者於一身的學習活動模式。因此，本 文擬先說明九年一貫課程的實施原則－「課程統整」的理念與模式，再提出能從課程、教學 、與評量三方面落實課程統整的具體教學方案－專題學習，最後述及專題學習的評量設計。 盼此論述結果，能為即將上路約九年一貫課程和國小現場教師提供一線曙光，以具體可行的 建議，進而產生實質上的助益。 　孩子們的學習需要動機，優質的教學更需要老師的熱情參與。本文嘗試以專題學習方式 做為經營九年一貫課程的一個範例，寄盼集課程、教學、評量於一身的專題學習，能早日實 現二十一世紀的教育願景－主人教育、溫馨校園、與終身學習。

　　　　　Over the past decade, the 9-year joint curricula plan for elementary and junior high schools is the most important educational revolution in Taiwan The movement of educational reform shows a fact that we are facing a period of disturbance in education Meanwhile, we have the opportunity to participate the plan of education reconstruction. Externally, the 9-year joint curricula plan only restricts in curriculum area. However, its deep inside extends to instruction and assessment dimensions. On the surface, the curricular reform meets the expectation of the society toward educational revolution. Actually, the 9-year joint curricula plan activates the reform of instruction and assessment simultaneously, and then and overall changes either in qualitative or quantitative dimension. Given the Guidelines for a 9-year joint curricula plan, it's easy to see through that the foci of this reform are the emphasis of integrated knowledge, the learning and application of basic competency, and the activity-and conception-based curricular design, especial in science education. In order to achieve the goals of 9-year joint curricula plan, the author believes that project-based learning is an excellent choice among many possible alternatives Not only the idea of project-based learning matches the thoughts of the curricular reform, but also it is a three-in-one of curriculum instruction, and assessment The project-based learning applies driving questions to encourage children's interest and motivation, thus learn actively Through the project-based learning activities, the more importance is that children learn a lot of scientific inquiry skills and plentiful science information In other words, it is a teaching-learning model which matches the goals of 9-year joint curricula plan in science field . Through the project-based learning, it will integrate instruction and assessment in classrooms, to raise the pedagogical quality of teacher, to foster students' inquiry ability and active learning. The students can apply what they have learned from PBL to daily lives, and know how to communicate with people effectively, to cooperate with other, to think independently, and solve problems The project-based learning can stimulate even children's potential creativity. These are the author's expectations to propose this instructional-leaning model.
