Students’ characteristics,self-regulated learning,technology self-efficacy,and course outcomes in online learning

The purpose of this study was to examine the relationship among students’ characteristics, self-regulated learning, technology self-efficacy, and course outcomes in online learning settings. Two hundred and fifty-six students participated in this study. All participants completed an online survey that included demographic information, the modified motivation strategies learning questionnaire, the online technology self-efficacy scale, the course satisfaction questionnaire, and the final grades. The researchers used structural equation modeling to examine relationships among student characteristics, self-regulated learning, technology self-efficacy, and course outcomes. Based on the results from the final model, students with previous online learning experiences tended to have more effective learning strategies when taking online courses, and hence, had higher levels of motivation in their online courses. In addition, when students had higher levels of motivation in their online courses, their levels of technology self-efficacy and course satisfaction increased. Finally, students with higher levels of technology self-efficacy and course satisfaction also earned better final grades. Based on the findings, we recommend that instructors design courses in a way that can promote students’ self-regulated learning behaviors in online learning settings and that students in online classes, as in traditional classes, set aside a regular time to concentrate on the course. Also, institutions should provide user-friendly online learning platforms and workshops for instructors and students to facilitate the teaching and learning experiences.     

Treatment and hydraulic performances of the NiiMi process for landscape water

This paper describes the NiiMi process designed to treat landscape water. The main aim of the research was to investigate the feasibility of NiiMi for removing organic and nutriment materials from landscape water. During the batch-scale NiiMi operation, the removal rates of color ranged from 66.7%o-80% , of turbidity from 31.7%-89.3%o, of chemical oxygen demand （COD） from 7%-36.5%, of total phosphor （TP） from 43%-84.2%, of soluble phosphate from 42.9%-100%, of total nitrogen （TN） from 4.2%-46.7%, and of NH4^＋-N from 39.3%-100% at the hydraulic loading of 0.2 m^3/（m^2·d）. Results showed that the removal efficiencies of COD, TP, soluble phosphate and TN decreased with the decline in the temperature. The NiiMi process had a strong shock loading ability for the removal of the organics, turbidity, TP, soluble phosphate, TN and NH4^＋-N. Three sodium chloride tracer studies were conducted, labeled as TS 1, TS2, and TS3, respectively. The mean hydraulic retention times （mean HRTs） were 31 h and 28 h for TSI and TS2, respectively, indicating the occurrence of a dead zone volume of 12% and 20% for TS 1 and TS2, respectively. TS 1 and TS2 displayed the occurrence of short-circuiting in the NiiMi system. The comparison results between TS1 and TS2 were further confirmed in the values obtained for some indicators, such as volumetric efficiency （e）, short-circuiting （S）, hydraulic efficiency （2） and number of continuously stirred tank reactors （N）.     

理性价值观下的我国“高校扩招”再辨析

经历了十年的发展历程,我国高校扩招在目的、实施过程以及实际结果等方面受到了一定的质疑。借鉴发达国家高等教育大众化的经验,联系我国经济和社会发展现实,我国高校扩招是教育要适应生产力的必然结果;发展初期的师资不足、质量下滑是高等教育大众化过程中的必经阶段;大学生就业压力的根源在于岗位短缺与人力资源过剩之间的矛盾,高等教育担负就业和普及素质教育的双重任务,就业率不是衡量其质量的唯一指标。

建构主义理论指导下英语网络自主学习能力的培养

笔者根据多媒体课堂教学与网络自主学习相结合的大学英语2+2+2教学模式的实践,通过教学反馈与问卷的调查分析,发现新教改模式下学生英语网络自主学习能力相当低。基于此,本文提出建构主义理论指导下的英语网络自主学习能力培养的主要途径。     

Advocating Students’ Individual Learning

A new approach formed with the application of modern teaching facilities makes English teaching and learning more collaborative and individualized through using computers,the Internet,and multimedia.Therefore,students’individual English learning,teaching and learning environment,and conditions that students need in their individual learning are discussed.     

论西方学习自由的历史演进

学习自由是高等教育的基本原则之一,近几年来越来越受到学者们的重视。从历史学的角度来探讨学习自由的演变轨迹,可以将其分为早期实践期、正式形成期、大发展时期三个历史阶段,进而得出以下结论：学习自由既是一种思想,也是一种价值目标;学习自由是一种相对的自由,对学生而言,在享受学习自由的同时,还要履行相应的社会义务和责任;学习自由的历史发展演变折射出高等教育的理念一直处于不断发展变化之中。     

建构主义学习理论与汉语教学

作为“当代教育心理学中的一场革命”的建构主义,是学习理论中行为主义到认知主义以后的进一步发展。它强调学生的主动学习,要求学生由外部刺激的被动接受和知识的灌输对象转变为信息加工的主体和知识意义的主动建构,同时也重视教师在学生建构知识的过程中提供一定的帮助和支持。这无疑为我们建立一种面向建构主义的第二语言教学论提供了一个观照的视角,同时促使我们完善汉语教学,贯彻以“逐步扩展,从句子向话语发展”为基本内容的汉语知识教学。     

学习兴趣转变,研究生教育改革刻不容缓——基于学习者利益的视角

目前研究生教育正在面临着学习者兴趣变化的巨大挑战。研究生学习兴趣变化主要体现从重视理论知识学习转向注重应用实践能力的提高上。这些变化既是社会发展需要的反映,同时也是就业压力的反映。研究生教育必须根据学习者学习兴趣的变化而进行适时的调整,把培养重心转向实践应用能力提高上。这一调整是提高研究生教育质量的根本对策。
