寻找灵魂的现代人--陈染小说思想内涵探析

在中西文化的交汇处,在"知生知死"的终极意义上,个体有限生存面对无限广袤世界,对生命的意义进行形而上的追问,以此确定人生的价值取向、处世态度,这是陈染在小说领域坚持的一个可贵姿态,亦是中西文化的一个敏感的交接点.我们发现,经历了文艺复兴,经历了启蒙运动,科学和理性发达与伸张,进入现代化的西方世界,并未获得精神的平衡与满足,依然保持着对生命形而上追问的焦灼和对精神家园的瞩望,"生命不堪承受之轻".陈染以其聪慧和敏感,率先探足在寻找现代人精神家园的道路上,并在这条精神探险的道路上走得心事重重、困厄重重.

Development of system thinking skills in the context of earth system education

The current study deals with the development of system thinking skills at the junior high school level. The sample population included about 50 eighth‐grade students from two different classes of an urban Israeli junior high school who studied an earth systems‐based curriculum that focused on the hydro cycle. The study addressed the following research questions: (a) Could the students deal with complex systems?; (b) What has influenced the students' ability to deal with system perception?; and (c) What are the relationship among the cognitive components of system thinking? The research combined qualitative and quantitative methods and involved various research tools, which were implemented in order to collect the data concerning the students' knowledge and understanding before, during, and following the learning process. The findings indicated that the development of system thinking in the context of the earth systems consists of several sequential stages arranged in a hierarchical structure. The cognitive skills that are developed in each stage serve as the basis for the development of the next higher‐order thinking skills. The research showed that in spite of the minimal initial system thinking abilities of the students most of them made some meaningful progress in their system thinking skills, and a third of them reached the highest level of system thinking in the context of the hydro cycle. Two main factors were found to be the source of the differential progress of the students: (a) the students' individual cognitive abilities, and (b) their level of involvement in the knowledge integration activities during their inquiry‐based learning both indoors and outdoors. © 2005 Wiley Periodicals, Inc.
