党的民族政策对西藏发展的作用

新中国成立以后,中国共产党从西藏实际出发,顺应历史发展潮流,积极促成西藏和平解放,推动西藏民主改革,实行民族区域自治,进行大规模的现代化建设和改革开放。这一系列的重大举措,不仅深刻地改变了西藏人民的命运,对西藏的发展更是有着无法估计的深远作用。     

闲游之乐与警世之谈——徐灵胎及其《洄溪道情》

徐灵胎是清代杰出的医学家,他所作的《洄溪道情》属于诗歌道情,是清代道情的代表作之一。《洄溪道情》扩大了道情的题材,以儒家的警世教化思想为主,半为警世之谈,半写闲游之乐。徐灵胎还辨正道情之曲,并推广其音,表现出文人从事说唱文学创作的高度自觉性。

Different influence of contextual educational factors on boys＇ and girls＇ reading achievement

The results of lEA （The International Association for the Evaluation of Educational Achievement） PIRLS 2006 （Progress in International Reading Literacy Study） has showed that Latvia has the 6th largest gender gap in reading literacy scores and that is an indication of a serious problem of education in this country. The purpose of the paper is to find out reasons behind boys＇ low achievement to help improve their reading literacy. The proposed hypothesis is that boys and girls are differently affected by the same factors. If that is so, teachers, parents and other education practitioners should be aware of this fact to adapt reading literacy studies for both genders at maximum efficiency. In this research, PILRS 2006 data are used and different structural equation models are created to find out which factors have the most influence on boys＇ reading achievement. Structural equation modeling （SEM） is based on achievement scores and student and parent questionnaire data. The model formed using all population data was applied to boys＇ and girls＇ data separately to observe different influence of the same factors on students reading achievement scores. The comparison of standardized coefficients of structural equation model among five countries （Spain, Russian Federation, Lithuania, Latvia and Trinidad and Tobago） has been performed. Running the same model over different boys＇ and girls＇ data of different countries has showed that the strengths of relationships among the variables are similar. It was expected to observe noticeable differences between SEM coefficients of boys＇ and girls＇ data, but it turned out that big gender differences in reading achievement does not mean big differences in standardized coefficients of structural equation model and vice versa. It is found that school environment has greater impact on boys reading literacy.     

Question Posing, Inquiry, and Modeling Skills of Chemistry Students in the Case-Based Computerized Laboratory Environment

A new learning unit in chemistry, Case-based Computerized Laboratories (CCL) and Computerized Molecular Modeling (CMM) was developed at the Technion. The CCL and CMM curriculum integrates computerized desktop experiments and molecular modeling with an emphasis on scientific inquiry and case studies. Our research aimed at investigating the effect of the CCL and CMM learning environment on students’ higher-order thinking skills of question posing, inquiry, and modeling. The experimental group included 614 honors 12th grade chemistry students from high schools in Israel who studied according to this learning unit. The comparison group consisted of 155 12th grade chemistry honors students who studied other chemistry programs. Pre- and post-tests questionnaires were used to assess students’ higher-order thinking skills. Students’ responses were analyzed using content analysis rubrics and their statistical analysis. Our findings indicated that the scores of the experimental group students improved significantly in question posing, inquiry and modeling skills from the pre-test to the post-test. The net gain scores of the experimental group students were significantly higher than those of their comparison peers in all three examined skills. In modeling skills, experimental group students significantly improved their achievements in making the transfer from 3D models to structural formulae, but only about half of them were able to transfer from formulae to 3D models. By presenting a case-based chemistry assessment tool and content analysis of students’ responses in this paper, we enable teachers and educators to analyze their students’ higher-order thinking skills both qualitatively and quantitatively.     

数学分析习题课教学探讨

以普通高等院校数学教育专业的学生为平台,结合其数学基础相对薄弱的实际情况和教学实践,《数学分析》习题课教学应遵循的4条教学原则：其一,充分备课、严格选题、作业中的典型错误及时剖析纠正、不单纯讲评作业充分发挥习题课优势;其二,在进行《数学分析》课程教学和习题教学时,应“计算能力”和“分析能力”并重;其三,师生互换角色的动态教学方案;最后,习题课采取分层施教、小班施教的优势和原则．     

基于UML的实验室调度系统需求分析

UML（Unified Modeling Language）是面向对象方法建模的语言标准工具,在系统建模过程中应用很广泛。在UML技术指导下,针对软件开发过程中的需求分析阶段,提出了一种结构清晰的功能需求分析模型,在系统用例图的基础上,建立类图和时序图,从静态和动态不同侧面表达系统模型,迭代的建模过程保证了模型的一致性。最后以一个实例详细描述了系统功能需求分析建模的过程。
