Enhancement of Quality in Chemical Inquiry by Pre-University Students

Our pre-university chemistry students face problems achieving sufficient quality in chemical inquiry. To try to enhance the quality of student performance in chemical inquiry, Dutch pre-university chemistry students (age 17) carried out an authentic research project on Diffusion of ions in distilled water. The learning materials for this student inquiry project, the teaching scenario and the website were designed in cooperation with five chemistry teachers. Three teachers from this network and two other teachers also implemented the project with 80 students to find out whether the emphasis on relevant concepts of evidence (CoE) improves the quality of student inquiry outcomes. This part – with its emphasis on the CoE – in the student inquiry task is based on four key features: the students feel motivated to explore, focus their attention on, give meaning to and reflect upon CoE. In teams students conducted a guide experiment, analysed a scientific article, did an inquiry and wrote a report, discussed CoE with peers on the Internet and rewrote their reports. All lessons were observed, field notes were made and analysed on whether the intended student activities had been realised. The Internet discussion was recorded in a database and analysed. The first and final reports of all teams were coded and analysed. Also the students appreciation of the activities was assessed. The teaching and learning activities were realized to a very large extent as planned in the design. The emphasis on CoE resulted in 65% of the students achieving a sufficient level of quality in their final reports.     

用MATLAB符号工具箱编程求常微分方程的通解

用MATLAB的函数dsolve解常微分方程时,只能得出解析解,对于解的结果只能用隐式来表示的情况,dsolve便无能为力.因此,用dsolve对某些齐次微分方程和全微分方程求解时,MATLAB往往得不到有用的结果.本文利用MATLAB符号工具箱,通过编程可求出齐次方程的解,通过自动寻找积分因子,从而求出全微分方程的通解,另外指出文献[3]中的一个错误.

The effect of inquiry‐based learning on the achievement goal‐orientation of grade 10 physical sciences learners at township schools in South Africa

Due to apartheid policies, Black African learners in South Africa have been severely disadvantaged in school science. Despite policy changes to redress these historical imbalances, Black African learners continue to underperform in science. Previous research has identified motivation as a key factor that impacts performance. Achievement goal orientation is a construct of motivation that explains learning behaviour. In an attempt to address the problem of learner motivation, this study investigated the effect of inquiry‐based learning on the achievement goal‐orientation of grade 10 physical sciences learners at historically disadvantaged township schools in South Africa. In South Africa, the term “township” usually refers to under‐developed urban areas that were historically created for “non‐whites” during the apartheid era. The findings showed that the experiment group of learners who experienced inquiry‐based learning significantly gained in mastery goal orientation, while the control that were taught through a traditional direct didactic approach had an insignificant change in their mastery goal orientation. From these results, it can be concluded that inquiry‐based learning does support a mastery goal orientation in learners. This orientation is regarded as desirable because mastery approach goals could support positive outcomes in conceptual learning, leading to an improvement in science achievement of learners.     

二十一世纪全球化背景下大陆中文歌曲英译现状研究

随着改革开放和社会主义现代化建设深入推进,我国对外交流不断加深,越来越多的大陆中文歌曲被译成英文歌曲。但是,这些英译歌曲散见于各种新媒体上,也少见国内对相关的文献音像资料进收集整理。依托大学生创新训练项目,小组成员采用文献阅读法,利用课余时间对全球化背景下2019年3-8月间大陆中文歌曲及其英译版歌曲进行搜集、整理和分类,搭建微信公众平台进行传播,并对影响其传播的因素进行探究,提出相应对策。     

张掖市妇女乳腺癌知识知晓率调查及健康教育对策分析

[目的]了解张掖市适龄女性对乳腺健康知识及乳腺癌的认知情况和乳腺自检现状,探讨其影响因素,为乳腺健康教育的实施及提高主动预防意识提供可行性依据。[方法]抽取张掖市五县一区18—65岁当地妇女1200人以问卷调查的方式进行乳腺健康知识、乳腺癌相关知识的调查,应答率99.6%。[结果]在调查的1195人中,调查对象对乳腺健康知识与乳腺癌概念混淆,对乳腺健康知识与乳腺癌认知途径主要来源于电视与社会教育,对乳腺癌认知较清楚的更是基于周边有乳腺癌患者的基础上;对乳腺癌的危险因素认知,城乡差距显著;乳腺癌治疗现状及生存状态认知不够。[结论]张掖市妇女对乳腺健康知识与乳腺癌的相关知识认识不足,对乳腺癌的治疗信心偏低,乳腺健康知识与乳腺癌认知途径单一、信息缺乏,应通过多元化健康教育加强妇女对乳腺健康知识的了解,提高妇女乳腺健康知识与癌的认知水平,加入疾病主动预防的健康队伍中来。     

制约商科大学生创新思维培养的因素研究

文章对制约商科大学生创新思维培养的因素进行了调查,并进行了统计分析,认为制约商科大学生创新思维培养的因素至少有15项,这些因素从大到小依次为:就业压力导致学生急功近利、大学生的创新经费不足、学校硬件不足、个人的教育理念陈旧(重应试、重具体知识)、考试方式陈旧、老师在创新方面的引导和示范不够、学校缺乏自由创新的环境氛围、学校没有实行导师制、教学方式陈旧、学校考评方面对创新重视不够、学生知识结构不合理、科技意识差、社会对大学教育的认识观念陈旧、课程结构不合理、缺乏崇高的理想。制约商科大学生创新思维培养的因素的大小存在一定的差异,关于学校间、专业间、年级间、性别间、性格间的差异,有的显著,有的不显著。
