The effect of goal-setting prompts in a blended learning environment—evidence from a field experiment

Previous literature has shown that task-based goal-setting and distributed learning is beneficial to university-level course performance. We investigate the effects of making these insights salient to students by sending out goal-setting prompts in a blended learning environment with bi-weekly quizzes. The randomized field experiment in a large mandatory economics course shows promising results: the treated students outperform the control group. They are 18.8% (0.20 SD) more likely to pass the exam and earn 6.7% (0.19 SD) more points on the exam. While we cannot causally disentangle the effects of goal-setting from the prompt sent, we observe that treated students use the online learning platform earlier in the semester and attempt more online exercises compared to the control group. The heterogeneity analysis suggests that higher treatment effects are associated with low performance at the beginning of the course.     

混合学习环境下英语学习策略使用的性别差异研究

本文以Oxford的语言学习策略量表为基础,采用问卷和访谈的形式调查了某地方高校200名非英语专业学生在混合学习环境--传统课堂教学和网络教学相结合的学习环境下,语言学习策略使用的性别差异情况。研究结果表明,男生和女生各自的总体策略使用频率仅为"有时使用",女生的使用频率略高于男生;在单项策略中,男、女生更频繁的使用补偿策略,很少使用社会策略;比之传统课堂环境,男、女生在网络环境下更频繁地使用情感策略。

高校教师的“混合式学习”接受度及其影响因素研究——以北大教学网为例

以北京大学教学网为案例,对混合式学习的教师接受度进行了深入地研究。根据混合式学习及科技接受理论(TAM),研究者构建出了一个分析模型,包括技术特点、教师特点、课程特点、主观规范和服务品质特这五个维度,以认知有用性、认知易用性为中间变量,并以北大教师"使用意图"为因变量。通过定量分析,提出了影响北大教师接受混合式学习方式的诸种因素,并对混合式学习的推广与应用提出了若干建议。     

分布式教学范式对集体智慧的激发

以网络为核心的多媒体技术的发展与新一代e-learning的出现对传统教学范式下的教师来说,既是契机也是挑战。分布式认知是信息技术发展而催生的新理论,面对混合式的学习环境,以它为指导的为分布式认知教学范式展现出了独特的优势。它不仅为教师提供了全新的视角审视课堂环境,并且能够从学习方式、学习者、知识等方面培养集体创新创造、共同合作的能力,为集体智慧的激发创造条件。通过课堂观察与实例分析表明,运用分布式教学范式不仅能优化课堂环境内各种分布式资源的整合,同样的,高效多元的资源利用与共享也能激发集体智慧发挥更大的价值,从而使得课堂效果最大化。     

小学数学混合式教学探究

混合式教学模式是教学新形势下的新型教学模式,能够有效提升数学教学的有效性。在小学数学课堂教学中运用混合式教学,能使学生对数学学习更感兴趣。教师应引导学生养成自主学习、深入学习数学的心理,使小学数学教学模式成为更适合社会培养数学人才的有效教学模式。     

A case study of third grade students’ perceptions of the station rotation blended learning model in the United States

The purpose of this case study was to explore the experiences of 31 third graders who experienced learning in a Station Rotation blended learning setting over the period of one semester in the United State. These students participated in student focus group interviews and completed student questionnaires during the middle and the end of the semester. The student focus group interviews were first transcribed and coded. The students’ responses from the questionnaires were then coded and compared with the findings from the student focus group interviews. The results revealed five positive themes (variety of activities, technology, learning, fun, and getting help) and two negative themes (challenging work and technology). These emerged themes from the student focus interviews and the student questionnaires explain the perceptions the students had about the Station Rotation blended learning model. Finally, discussion for current study as well as recommendations for future research were provided.

A family of quasi-cubic blended splines and applications

INTRODUCTION Bézier curves and uniform B-spline curves are powerful tools for constructing free form curves and surfaces (FFC/FFS). But they cannot represent the arcs, hyperbola, sphere, cylinders and other transcendental curves and surfaces exactly. In order to avoid the in- conveniences, many bases are presented in other new spaces (Zhang, 1996; Pe?a, 1997; Walz, 1997; Sánchez-Reyes, 1998; Mainar et al., 2001). Note that, these existing methods can deal with both polynomial curve…     

Mechanical engineering at RWTH Aachen University: professional curriculum development and teacher training

This paper offers a multi-perspective view on engineering education at RWTH Aachen University: curriculum design, examples of newly developed teaching methods for engineering curri-cula, and teaching competencies and teacher qualification. It is based on the theories of student-centred learning, project learning, social skills, etc., but the paper covers the practical implications and ways of implementation of these items in a current design process of a new study programme: In the course of the Bologna process the mechanical engineering study programme of RWTH Aachen University has encountered a complete and thorough revision responding to the need of present-day technical students and—accordingly—to the fast-growing requirements of the engineering industry. This change process will be presented. A case study from engineering informatics shows concepts for modern teaching methods, responding to the requirements of students and industry, especially regarding social skills. Teaching competencies have to change and grow accordingly. Thus, a concept for the improvement of educational skills and abilities of engineering teachers—integrated into their work process—is demonstrated.
