| Summary: | 碩士 === 國立臺灣師範大學 === 資訊教育學系 === 96 === Teacher professional development is aimed to elevate teachers’ three abilities of cognition, modality and skill, and to promote the development and innovation of the whole school educaton. The ways of improving teacher professional development are various, and portfolio has become the important issue. Although the digitalization is in the current trend, the lack of interaction between the readers and the rapid updating of the webpage style is the main flaw, which blog, however, outwit. This research thus combines blogs and portfolios to construct the blogolios.
Design-based Research is applied in this research, taking analysis, design, development, implementation, and evaluation as a cycle. Each requires questionnaires and interviews to understand the satisfactory degree and suggestion of the teachers toward the system, serving as the basis of the modification of next platform version. 1090 elementary and junior high teachers participate in this research and follow the five cycles listed below:
1st version: teachers’blogs (beginning of construction)2nd version: blogolios (integration of evaluation)3rd version: blogolios (flexible interface between the official and teachers’ version)4th version: blogolios (interaction between communities)5th version: blogolios (clear and fine webpage style)
Through the five cycles and analysis of questionnaires and interviews, four findings are covered in this research: 1. The blogolios improve the teacher professional development. 2. The related media functions should also be heeded during the construction of system. 3. The external environment, internal learning motivation, background information and the easy accessibility to the platform functions all exert the influence on teachers’ preference of utilizing the system. 4. The habit of sharing and the judgment of one’s knowledge also affect the inclination of teachers to share their teaching materials or resources.
