Practice and reflection of principals’ transformative curriculum leadership in a Taiwan KIST school
Huan‐Kan Tseng,Chuan‐Chung Hsieh,Robin Jung‐Cheng Chen 한국교육개발원 2021 KEDI Journal of Educational Policy Vol.18 No.2
This study adopts the framework of transformative curriculum leadership theory, focused on one privatized school, the KIST (KIPP Inspired Schools in Taiwan) school, as a case study. The authors mainly utilize interview methods to explore the practices of principals’ transformative curriculum leadership in the KIST school, and find that the case of school principal leadership successfully integrates the interactions from the school autonomy, the local educational authority, and the private foundation into a driving force to develop a new educational model. Such results not only restructure the subjectivity of school education, but also effectively provide the reference framework for policy correction and solutions to the contemporary problems of rural education.

The purpose of this qualitative study is to present and shape successful indigenous school principal leadership in Taiwan. We focus particularly on a principal’s attitudes to change, how this influences principal leadership practice and ultimately its contribution to improving school performance. The study captures and analyzes opinions of the stakeholders of an indigenous school on principal leadership to understand how the principal leads the school to successful transformation. The results show that indigenous principal leadership emphasizes harmonious collective relationships, equality of power, spiritual satisfaction and collectivism. The ancestral soul is especially rooted in the principal’s philosophy and values, such that the principal makes good use of the blood ties between schools and tribes, and creates a community of a shared future, facing difficulties together. The findings contribute to the body of knowledge on shaping successful indigenous school principal leadership, which transforms the internal and external environmental factors into the forces for successful school change and benefits the stakeholders.

This study used three types of agricultural waste, Citrus maxima peel, passion fruit shell, and sugarcane bagasse, to produce biosorbents for copper(II), cadmium(II), nickel(II), and lead(II) metal ion removal in a fixed-bed column. The biosorbent properties were characterized using scanning electron microscopy, zeta potential analysis, Fourier transform infrared spectroscopy, and cation exchange capacity. The adsorption capacities were determined using the Thomas model for various pH values and flow rates. The results indicated that biosorbents possess carboxylic acid groups, which function as exchangeable cation and complexation sites for removing heavy metals. The biosorbents exhibited great adsorption capacity.

Loosened by the laws and regulations, Taiwan’s alternative educational policy has allowed public schools to conduct school-wide curriculum transformation experiments, which is a possible opportunity for Taiwanese aborigines who have been subjected to long-term oppression and assimilation to separate from the mainstream ideological educational framework. In this change process, the school principal-led curriculum transformation has become an important way to seek a new educational model. This paper qualitatively investigates two alternative schools for Taiwanese aborigines that have undergone successful transformation and collects the views of the principals, directors, team leaders, and teachers (eight persons in total) in two schools on the school principal-led curriculum transformation. Through summarizing and analyzing relevant data, this paper proposes that the principals of Taiwanese aboriginal schools effectively change the teachers’ beliefs, curriculum structure, and school culture through the systematic practices of “belief change” and “structural innovation,” and establish a curriculum paradigm different from mainstream education, which realizes a certain knowledge transfer effect. The transformative curriculum leadership process can be summarized into the conflict awakening and positioning stage, the experimental and interactive development stage, and the revision and transformation stage. This study intents to provide a reference for Taiwan’s educational reform and encourage the principals of other alternative schools to picture the connotation and value of transformative curriculum leadership and establish more new curriculum models of alternative education.

Voltage Equalizing of Solar Modules for Shadowing Compensation
Jou, Hurng-Liahng,Wu, Kuen-Der,Wu, Jinn-Chang,Chung, Cheng-Huan,Huang, Ding-Feng The Korean Institute of Power Electronics 2017 JOURNAL OF POWER ELECTRONICS Vol.17 No.2
This paper proposes a shadowing compensation method for the solar modules of grid-connected photovoltaic generation systems. The shadowing compensator (SC) implemented by the proposed shadowing compensation method is used only for the solar modules that can be shaded by predictable sources of shading. The proposed SC can simplify both the power circuit and the control circuit as well as improve power efficiency and utilizes a voltage equalizer configured by a modified multi-winding fly-back converter. The proposed SC harvests energy from the entire solar cell array to compensate for the shaded sub-modules of the solar cell array, producing near-identical voltages of all shaded and un-shaded sub-modules in the solar cell array. This setup prevents the formation of multiple peaks in the P-V curve under shaded conditions. Hardware prototypes are developed for the SCs implemented by the conventional and modified multi-winding fly-back converters, and their performance is verified through testing. The experimental results show that both SCs can overcome the multiple peaks in the P-V curve. The proposed SC is superior to the SC implemented by the conventional multi-winding fly-back converter.
