情绪交互对在线协作学习者知识建构的影响

情绪交互可以在一定程度上决定在线学习者协作知识建构的成效。为了探究情绪交互的网络结构特征及其对在线学习者协作知识建构的影响程度,研究综合采用社会网络分析法和内容分析法,从整体网络视角分析在线协作讨论中情绪交互的网络结构特征,并依据Gunawardena提出的知识建构模型对在线学习者协作知识建构水平进行了分析。研究发现,情绪交互的连通性较低、密度整体不高、中心势偏高,而且在线学习者的协作知识建构总体水平也不高,主要集中于知识分享和知识分析层次。其次,情绪交互密度和中心势不仅与知识协商和知识修改之间存在显著相关关系,而且在一定程度上可以预测在线协作知识建构水平。鉴于此,文章从情绪交互视角提出了提升在线学习者协作知识建构水平的策略。     

在线学习中学习者对游戏化元素偏好的研究

整合游戏化学习理念是解决在线学习动机难以维持的方法之一,但对于落实该理念载体的游戏化元素,目前的理论和实证探索还处于初步阶段。鉴于学习者心理需求对于游戏化元素的选取至关重要,研究试图从学习者对游戏化元素偏好的视角开展研究,进而为利用游戏化元素优化在线学习提供参考。通过文献探讨,总结了游戏化元素的三分类体系(动力类、机制类、组件类),并设计了三维度偏好指标(有趣性、重要性、有用性)。对在线学习者的调查发现:(1)在线课程中只涉及部分游戏化元素,属于轻游戏化;(2)学习者对三类游戏化元素在整体偏好上没有差异;(3)学习者对三类游戏化元素在具体偏好指标上有所差异,对动力类元素偏好其重要性,对机制类元素偏好其重要性和有用性,对组件类元素偏好其有趣性;(4)对游戏化学习的态度会积极影响在线学习动机。基于上述结果,研究就如何针对不同学习需求选取适当的游戏化元素提出了相应建议。     

基于反思文本的慕课学习情感体验特征分析

慕课作为具有较强体验性特征的教育产品,在为广大学习者提供在线学习机会和优质资源的同时,也带来了独特的情感体验。通过对一门教师教育类慕课前、中、后期与情感体验表达有关的724条学习者反思文本的质性分析,确定了25种积极和消极情感体验,体现了慕课学习情感体验的特有状态,其中,较为常见的有满意、激励、期待、不满、警觉、充实、感兴趣、轻松、高兴、喜欢。从整体情感倾向来看,绝大多数情感体验是积极的,满意、激励与期待三种主要情感体验约占总体的80%,情感体验积极且集中。从课程阶段来看,三个阶段均以积极情感体验为主,前期情感体验表达最为丰富且种类多样,中期的消极情感体验最多。从情感体验指向对象来看,七成指向学习内容,两成指向学习者自身,而指向慕课学习形式、课程资源、学习活动和教师的情感体验相对较少。

A hybrid and flipped version of an introductory mathematics course for higher education

Abstract

This in practice paper describes the experience of seven lecturers in a hybrid and flipped version of an introductory mathematics course for higher education. In a Mexican university, lecturers adapted to this innovation supported by an adjusted Massive Open Online Course. The experience revealed the relevance of leaving conventional assessment processes to make way for an understanding of lecturers as a collaborative team, trying to transform their own perspective about the learning of mathematics. This experience is an example of the reconceptualisation of the teaching of STEM education that contributes towards a non-formal educational context, promoting lecturers’ education and dialogic transformative learning.

Media Naturalness and Online Learning: Findings Supporting Both the Significant- and No-Significant-Difference Perspectives

Is the use of an online course delivery format, when compared with the more traditional face‐to‐face format, good or bad in the context of university education? Those who subscribe to the no‐significant‐difference perspective argue that online delivery is good, because it allows students with time and geographic distance constraints to obtain the education that they need, with no significant negative impact on the quality of the learning experience. Others argue that online delivery is bad, advocating a version of the competing significant‐difference perspective, because the electronic communication media used for online delivery are not rich or natural enough to enable effective learning. This study contrasted students perceptions and grades in two different sections of the same course: one delivered entirely online and the other delivered face to face. Data were collected and analyzed at two points in time, namely, at the middle and end of a long semester. The study found support for both the no‐significant‐ and significant‐difference perspectives. At the middle of the semester, students in the online condition perceived communication ambiguity as significantly higher, and also obtained significantly lower grades, than students in the face‐to‐face condition. At the end of the semester, no significant differences were found.

Technology Readiness, Learning Goals, and eLearning: Searching for Synergy

More and more business schools are offering classes online or classes using a mix of face‐to‐face and online elements. In this article, we focus on how technology readiness and learning‐goal orientation influence students' preference toward these mixed classes. We conducted a large‐scale survey to determine whether students who are technology ready would place higher utility on enrolling in mixed classes and/or whether there exists a participation bias such that students with low learning‐goal orientation place higher utility on enrolling in mixed classes. We found that overall students who are more technology ready do place higher utility on enrolling in mixed classes, but that learning‐goal orientation does not influence this decision. We conclude with implications and recommendations for business schools that are interested in offering mixed classes.
