The development and initial validation of a questionnaire of inclusive teachers’ competency for meeting special educational needs in regular classrooms in China

The aim of this study was to develop and validate an instrument of inclusive teachers’ competencies for teaching students with special educational needs in China. Data were obtained from a preliminary and large-scale investigation in Beijing. The primary analyses included exploratory factor analysis and confirmatory factor analysis. The findings indicated that Chinese inclusive teachers’ competency is underpinned by four factors: teaching and instruction; communication and cooperation; attitudes and beliefs; and reflection and development. The four-factor model was obtained with satisfactory reliability and validity. The validated questionnaire generated a theoretical understanding of inclusive education teachers’ competency in China. In addition, the findings of the study provided knowledge that will allow for the development of professional standards and teacher education programmes for inclusive education.

有奖储蓄中奖号码的计算机分析

本文根据K.Pearson X~2的检验法,对中国工商银行浙江省分行1981年1月～1987年12月所有的由摇奖机摇出的有奖储蓄的中奖号码,利用电子计算机进行了统计分析.运算结果肯定了中国工商银行浙江省分行目前的摇奖方法是可靠的.也就是说,每个月在全省的某一地、市、县轮流用不同的摇奖机、不同的号珠,由不同的操作人员摇出中奖号码的方法,是行得通的.同时也指出,广大储户完全没有必要去择号购奖券,甚至买好以后再去调换所谓“中意的奖券,因为相对于信度10%而言,我们肯定了假设H:0～9这十个号珠中的每一个被摇奖机摇出的概率是相等的.”     

The effects of college students’ positive thinking,learning motivation and self-regulation through a self-reflection intervention in Taiwan

This quasi-experimental study examined the effects of a self-reflection intervention on college (college in this article refers to university-level education) students’ positive thinking, learning motivation and self-regulation in Taiwan. One hundred and two college students were selected to participate in an 18-week intervention forming the experimental group (EG) which emphasized providing main lecture, role-play, self-reflection activity, group discussion and group work. Another 179 college students from two other courses were selected as a comparison group. This study showed that supportive, resourced discussion with peers and instructor, self-reflection activities and assignment as a facilitative agent improved the EG students’ positive thinking, learning motivation and self-regulation. In addition, three structural equation models revealed that positive thinking had a strong and direct relation to Taiwanese college students’ pretest learning motivation (β?=?.85) and self-regulation (β?=?.77); learning motivation had a strong and direct relation to students’ pretest positive thinking (β?=?.86) and self-regulation (β?=?.81); and self-regulation had a strong and direct relation to students’ pretest positive thinking (β?=?.83) and learning motivation (β?=?.86). Instructional implications and research recommendations are discussed.
