关于亚洲东北部产细齿蹄盖蕨的分类位置问题

  The fern Athyrium crenulato-serrulatum  Makino  is  found  in  the  whole  of  Northeastern Asia embracing Northeastern China, Korea, Japan, Ussuri and the Far  East USSR. It is similar to the European Athyrium distentifolium, formerly known as A. alpestre, in having exindusiate round or  ovate  sori,  but  differs in  several  essential characters, such as the well-spaced fronds are biseriately arranged along a  thick and long-creeping rhizome, the base of stipe is thickened and not attenuated to- wards the point of attachment, the deltoid-ovate lamina with the basal pinnae as long as those next above, which all are distinctly petiolate and the rachis, costis and espe- cially the costules of pinnules clad in fine pale-colored generally septate hairs under- neath.  All these clearly show that the fern in question is not an Athyrium sen. str. neither Pseudoathyrium Newman  to which latter the fern was referred by Nakai. However, we have been long suspicious of its proper systematic position. In his recent monograph on the genus Cornopteris (Acta Phytotax. Geobot. 30: 104. 1979.) Kato has pointed out that C.crenulato-serrulata (Makino)  Nakai  “has  the  northernmost destribution in the genus and exhibits a few characteristics similar to Athyrium, the swollen base of stipes with projections and cartilaginous  lamina  margin.  By  these characteristics the species is clearly discriminated from other species”.  According to Kurita (1964), Mitui (1970) and Karo (1978) the species in question has chromosome numbers n=40, the base number of the subfamily Athyrioides instead of x=41, the base number of the subfamily Diplazioides including  Cornopteris  Nakai.  Since  thefern in question fits no other athyrid genera, hence a new genus is proposed.     

减少体育必修课是高校教学改革的必然趋势

随着社会经济、科技文化的飞速发展,面对２１世纪的挑战,减少体育必修课已成为高校教学改革的必然趋势。建立“减少体育必修课,增大选修比例,强化课外体育”的高校体育教学新体系具有现实意义。     

邏輯思維建安風骨悼念劉殿爵教授

劉殿爵教授過去了,大家要我說幾句話,我覺得十分惶恐.因為無論從輩份、學問、與劉教授的親近,抑或對他的瞭解而言,我部是不够資格的.當然,在過去二十五年間,我有幸和劉教授在中國文化研究所同事,得到他的指點和幫助,和他一起創辦了<中國語文通訊>雙月刊,更蒙他邀請我參加建立先秦兩漢典籍計算機數據庫,和編輯相關逐字索引,這都是緣分,也是我的幸運.不過,說來慚愧,由於學殖荒疏,精力分散,我對劉公實在說不上有多少拾遗補苴之功.     

《西藏植物志》新增补(2)

The present paper is the Supplement 2 to the Flora of Xizang,  based upon a collection in 1980 by Mr. W. L. Chen et al. from Mêdog,  the south-eastern part of Xizang.  In the paper 11 new species are desribed and 10 new-record species are repor- ted.  All the type specimens are kept in the Herbarium of the Institure of Botany, Academia Sinica (PE).     

An exploratory study on collaborative modes of professional development and learning for teachers of students with autism spectrum disorder (ASD)

This study aims to deliver a school‐based mode of training for in‐service teachers of students with ASD in Hong Kong. The training is delivered following the phases of implementation science, namely, exploration, installation, and implementation. The project team used the theory of mind approach, which enables teachers to engage with students with ASD and to focus on recognizing and reacting to emotions. Participants in this study included four educators from a teacher education institution, three expert teachers, and 19 in‐service teacher trainees. The most salient responses came from trainees who were provided with the opportunity to apply learned skills in their own classrooms immediately and to share the knowledge and skills in dealing with students with ASD in the post‐conference meetings.     

Determinants of Students' Quality of School Life: A Path Model

This study examined factors contributing to the quality of school life of secondary school students. A path model, expressing interrelationships between students' background characteristics, their expectations of schools, the perceived quality of both the formal and the informal school curriculum, the classroom environment and students' quality of school life, was developed and tested. The sample comprised 8265 Grade 12 students from 70 schools in New South Wales, Australia. Analysis indicated that, after controlling for other variables in the model, students' experience of the classroom environment was the single most important factor explaining their quality of school life. This revised version was published online in July 2006 with corrections to the Cover Date.     

Science and Mathematics Literacy: PISA for Better School Education

In this study, we explored how a teacher used a new mobile application that enables students to collect data inside and outside the classroom, and then use the data to create scientific explanations by using claim-evidence-reasoning framework. Previous technologies designed to support scientific explanations focused on how these programs improve students’ scientific explanations, but these programs ignored how scientific explanation applications can support teacher practices. Thus, to increase our knowledge about using mobile devices in education, this study aims to portray the synergy with an emphasis on a teacher’s practices when using mobile devices in 2 different units (water quality and plants). Synergy can be thought of as various scaffolds (scaffolds in the mobile application and the teacher support) working together to enable students to support creating explanations when using the mobile application. The findings of this study showed that the decrease in the teacher’s support for claims did not affect the quality of the students’ claims. On the other hand, the quality of students’ reasoning was linked with the teacher’s practices. This suggests that when supporting students’ explanations, focusing on components that students find challenging would benefit students’ construction of explanations. To achieve synergy in this process, the collaboration between teacher’s practices, professional development days, and scaffolds designed to support the teacher played a crucial role in aiding students in creating explanations.     

A comparison of scientific epistemological views between mainland China and Taiwan high school students

This study investigates the similarities and differences between high school students from Taiwan and China in terms of their scientific epistemological views. In addition, the effects of age and gender on scientific epistemological views were also examined. The results indicate that the students from these two localities, which signify two similar yet different cultures, are substantially different in five out of the six dimensions. Age and gender were also found to have significant effects in some dimensions. Implications for future research were discussed at the end of the paper.
