哈佛大学的CS50VR

https://www.class-central.com/report/harvard-cs50-virtual-reality/

https://www.class-central.com/report/harvard-cs50-vr/

哈佛大学的著名在线课程CS50是class-central选出的Top 50 MOOCs of All TIme,超过100万人在edX上选修了这门课程。在Virtually There: Documentary Meets Virtual Reality conference活动期间,哈佛大学宣布在2采用VR来拍摄著名的CS50课程。虚拟现实(VR)可以用来提升很多课程的体验,如医学、地理、历史、体育等,国家地理也推出了VR division

Jeremy Bailenson发表了一个VR将如何改变在线学习的演讲,在一个例子中,他通过VR有效的提高了学生的注意力。

CS50课程使用 Nokia OZO 进行拍摄,这个设备价值45000美元。

可以在这里看到全部的CS50VR课程。很有意思的是,因为VR可以看到教室中的场景,我们发现有不少课程是在一个空教室拍摄的。

Open edX与SCROM

SCORM (Shareable Content Object Reference Model),译做共享内容对象参考模型或共享组件引用模式,是目前最为人所熟悉及最被广泛采用的一套线上数字学习(Web-Base e-Learning)标准。SCORM 的建立解决长久以来不同来源的教学内容不能互通互享的问题。SCORM 是由美国国防部 (DoD,Department of Defense) 和白宫国家科学和技术政策办公室(OSTP,Office of Science and Technology Policy)在 1997 年所成立的一个名为「高级分布式学习」计划 (ADL (Advanced Distributed Learning) Initiative,以下简称 ADL)所倡议及建立的一套标准,目标是建立标准化及现代化(数字化)的教育及培训环境。

https://zh.wikipedia.org/wiki/SCORM

遗憾的是,至今Open edX仍然不支持SCROM。对于此,社区也一直在进行讨论。基本的思路有两种:

一种是通过第三方工具如SCROM Cloud来讲SCROM包装为LTI,然后再从Open edX调用LTI内容。具体的步骤可以见 https://blog.jazkarta.com/2015/02/08/adding-scorm-packages-to-open-edx-via-scormcloud-and-lti/

另一种是用Xblock来实现SCROM包的上传、解析、播放。appsembler和Raccoon Gang在这方面做了一些工作,开源了各自的Xblock。注意appsembler的Xblock使用了一个商业的Player JCA,所以不包含播放代码;我们将对Raccoon Gang的Xblock做进一步测试。

Open edX Ficus版发布

https://open.edx.org/blog/ficus-winter-20162017-release-open-edx-here

第6个Open edX版本Ficus(榕树)刚刚发布,感谢为这个版本作出贡献的人-特别是来自 EDUlib的Pierre Mailhot,他持续为发布最新版本进行测试。

Ficus在LMS和数据报告方面都有改进:

LMS

  • 新的”上一个”和“下一个”按钮来让学习者更直觉的导航。
  • 帖子列表不止包含标题,还有帖子里的第一行。这个改进在讨论区团队页面和行内讨论区都可见。
  • 进度页面加载显著加快。
  • 对于课程问题,确认最后确认按钮被整合为一个提交按钮,较少使用的动作(保存和显示答案)被移到了侧面。
  • 学习者可以很快看到问题是否已经被评分。
  • 课程讨论中的UI设计,包括帖子中的用户头像、新的头部区域、更直觉的主题列表和未读项目的指示。
  • 学习者可以根据投票来给讨论排序。

Studio and Course Author Tools

  • 课程团队可以在Studio中方面的拷贝和移动HTML组件。
  • For rescoring, course teams can specify that the system will only update a learner’s score if the process improves the learner’s score. For more information, see Rescore Learner Submissions for a Problem.
  • Using the advanced editor, course teams can include HTML tags inside the <label> and <description> elements for all CAPA problems.
  • Course teams can specify more than one correct answer for numerical input problems. For more information, see Adding Multiple Correct Responses.
  • For checkbox and multiple choice problems, course teams can use a <script> element to display different content depending on specified criteria, such as the time of day. For more information, see Using the Script Element for multiple choice problems and Using the Script Element for checkbox problems.
  • The randomized content block component type no longer includes the unused Scored field. (This action does not affect courses.) For more information, see Randomized Content Blocks.
  • Course teams can now create custom pages that are only visible to course team members with the Staff or Admin role. For more information, see Add a Custom Page.
  • In open response assessment (ORA) problems, the assignment is now correctly marked as complete when a course team member overrides a grade from a peer assessment. For more information, see Override a Learner’s Assessment Grade.
  • Improvements to the word cloud tool include a new Instructions field and accessibility updates.
  • For drag and drop problems, course teams can now prevent learners from receiving feedback until they’ve dropped all draggable items.
  • The “View this course as” feature now includes the capability to view the course as a member of a specific cohort.
  • The Student Profile report includes two new columns: “enrollment mode” and “verification status”.

Data

  • Insights现在提供单个学习者数据和新的“上一周的讨论区分享” 角度。
  • 5个分级的事件被增加:
    • edx.grades.problem.submitted
    • edx.grades.problem.rescored
    • edx.grades.problem.state_deleted
    • edx.grades.subsection.grade_calculated
    • edx.grades.course.grade_calculated

Configuration

  • Administrators can configure third party authentication differently for each of their sites.

Accessibility

  • On the video player, improved controls make downloading videos, transcripts, and handouts easier. Additionally, the video playback and volume sliders are now visible when learners view videos in high contrast mode.
  • Core CAPA problem types have been updated to help screen readers and keyboard users identify and respond to these problems.
  • Navigating among questions and reviewing survey results in the survey tool is now easier.
  • The contrast has been increased on the sign-in page for Open edX sites.
  • In Insights, the <title> element on learner pages now indicates the correct view when you switch between learner roster view and learner view.
  • The HTML structure of the Progress page has been reorganized, and the visual chart on this page is more accessible to learners who use keyboards and screen readers.
  • The course Home page uses heading levels 1-5 in a way that screen readers can more easily process.
  • For custom JavaScript problems, the jsinput tag includes a title attribute that helps orient non-visual learners.

Deployment Notes

With Ficus, the operating system for the Open edX platform changes from Ubuntu 12.04 to Ubuntu 16.04, the latest long-term support (LTS) version of Ubuntu. Ubuntu 12.04 reaches its end of life in April of this year. Unfortunately, upgrading Open edX from Ubuntu 12.04 to Ubuntu 16.04 is not possible. If your existing installation of Open edX is based on Ubuntu 12.04, we recommend that you build a new system.

教育操作系统

教育操作系统是在开源操作系统基础上集成了教育方面的开源软件,使得学校、家庭、社区可以方便的使用和维护。这里的开源软件多指桌面应用软件。

Edubuntu

Edubuntu is a grassroots movement, we aim to get Ubuntu into schools, homes and communities and make it easy for users to install and maintain their systems.

Debian-Edu

Debian-Edu (also known as Skolelinux) is a free and open source software project founded in Norway, now supporting all languages present in Debian. Its name is a direct translation of “school linux” from Norwegian, skole derived from the Latin word schola.

Fedora Education Spin

A special selection of applications related to educational and scientific purposes based on the Fedora distribution.

Guadalinux-Edu

Guadalinex-Edu is a custom Ubuntu spin deployed in Spanish schools.

OpenSuse-Edu

The openSUSE Education project tries to support schools using openSUSE, create and describe additional software-packages for educational projects and create an live CD for the regular openSUSE distribution.

Qimo for Kids

Qimo4kids is a kid-friendly desktop environment built entirely with free software. Qimo comes pre-installed with educational games for kids; TuxPaint, eToys, GCompris, Tuxmath, and Tuxtyping.

Uberstudent

Uberstudent is another Ubuntu-based educational distribution which aims at secondary and higher education. There is also an edition that runs the lightweight LXDE desktop environment that is meant to fit on a single CD.

Ubermix

http://www.ubermix.org/

Ubermix is extensively used in schools. The system was designed to store user data and software in seperate partitions. So, in case the computer malfunctions, the user can wipe out the operating system and resotre fresh copies quickly. From Ubermix founder, Jim Klein, in an Opensource.com interview:

Ubermix comes pre-loaded with a number of applications for education, productivity, design, programming, Internet, and multimedia construction. Education oriented applications like Celestia, Stellarium, Scratch, VirtualLab Microscope, Geogebra, iGNUit, and Klavaro, as well as educational games like TuxMath, TuxTyping, gMult, and Numpty Physics all bring with them plenty of opportunities to learn.

Internet applications we all know and love, like Firefox, Thunderbird, Chrome, Google Earth, and Skype are all there. Common productivity apps like LibreOffice, NitroTasks, Planner Project Management, VYM (View Your Mind), and Zim Desktop Wiki are too. Kids interested in design will find the GIMP, Inkscape, Scribus, Dia, Agave, and even TuxPaint for the younger ones. And apps like Audacity, Openshot, Pencil, and ffDiaporama help round out the media offerings. These, and many more, make Ubermix a powerful launchpad for student creativity and learning.

Sugar

https://www.sugarlabs.org/

Sugar was designed for the One Laptop per Child program. It is an easy to use and kid-friendly operating system. Children who love exploring will figure out things quickly in this environment, even if they cannot read or write yet.

From Sugar Labs:

Information is about nouns; learning is about verbs. The Sugar interface, in its departure from the desktop metaphor for computing, is the first serious attempt to create a user interface that is based on both cognitive and social constructivism: learners should engage in authentic exploration and collaboration. It is based on three very simple principles about what makes us human.

endlessos

开放教育平台OpenET

network-diagram-3

开放教育平台是开源教育技术理念在学校的落地框架。当前高等院校采用的信息技术来自三个方面:

1.以招标采购方式购买的教育信息化公司产品及服务。

2.独立研发适用于本校的软件。

3.采用开源软件进行定制化。

这当中,招标购买方式是大多数高校的主流。但由于决策流程慢、招标过程复杂、教育信息化公司水平良莠不齐,导致在具体的落地中出现各种问题。即使当时项目实施成功,对于封闭的技术方案和代码,后期运维完成取决于厂商,具有不可控性。很多高校已经意识到这个问题,因此部分具有研发实力的高校组建团队自己研发软件,定制软件的可控性高,但是在安全性和产品可用度方面具有挑战。采用开源软件是一个逐渐发展的趋势,开源软件具有较高的安全性,适用于和业务关联不是很紧密的需求如社交和科研。
