Lecture recording refers to the process of recording and archiving the content of a lecture, conference, or seminar.[1] It consists of hardware and softwarecomponents that work in synergy to record audio and visualcomponents of the lecture. It is widely used in universities and higher education in the UK and Australia to provide support for students.[2][3] 71% of institutions replying to a UCISA survey in 2016 indicated that this technology was available in their institution.[4] Where lecture recording is done at scale the recording system may be integrated with the timetabling system and the collection of metadata may be automated.[5]
Screencastify is the #1 free screen recorder for Chrome. No download required. Record, edit and share videos in seconds. Videos autosave to your Google Drive, and can be published directly to YouTube. I recommend taping lectures (and sitting up front so you get the best recording). For my recent micro class, I recorded with the digital IC Recorder ICD-P28 by Sony. It records up to 9 hours. It has 5 folders so on Monday's class I would record lecture in Folder A, Tuesday in Folder B etc. Then I would relisten to the recorder while walking. Record Lectures Use your Windows laptop to record lectures and take notes for fast review. Meeting Recorder 9 makes it easy to record lectures and take lecture notes. Use your laptop computer to capture every word and take notes with a single click. The annotated recording can be used to quickly recall important points in the lecture,. Strategies for recording lectures, (with a focus on the Olympus DM670), but relevant to any recording device you might use in a lecture situation.
Hardware[edit]
Hardware is used to capture the lecturer's voice along with the video of the lecturer. Cookie 5 5 6 – protect your online privacy. Sometimes, the lecturer may use visual aids to support their speech, such as slide shows, which are presented to the audience with some kind of projector. In this case, such slide shows can also be recorded. Once captured, the data is then either stored directly on the capturehardware or sent to a server over a LAN or the Internet. After some processing to adapt the video formats to the desired distribution mechanism, codecs, etc., viewers are then able to remotely access the recording, either in real time or ex post facto.

The recording of a lecture or presentation may use any combination of the tools: Microphone, Camera, Screen capture, Presentation capture, or Document camera.
Software[edit]
A university lecture
Software is used both on the capturehardware, the viewer's computer, and the production server. Software ranges from simple web browsers and video players to stand-alonesoftware programs made specifically for viewing lectures. The viewer's as well as the presenter's software must be compatible with the software on the server which receives the content from the capturehardware, produces it, and sends it to the viewer's computer on-demand.[6]OpenCast is an open-source video capture system available in higher education.
Modern lecture recording software supports advanced features such as indexing through OCR, instant search, real-time video editing and annotation, along with other advanced features.[7]
Uses[edit]
Lecture recording is often used in the flipped classroom learning model as a means to provide materials outside of traditional lectures or seminars. Students are able to self-study by playing back and interacting with recorded lectures.[8]
Some educational institutions use lecture recording as a means to replace the traditional classroom with an online classroom. Lecture recording can also be used to create reference materials as a supplementary resource.[9] Lecture recording is not always welcomed by university faculty.[10] Faculty attitudes to this kind of technology enhanced learning may vary across disciplines.[11] Student research has found that more students than staff expect lecture recording to be beneficial to learning. In the most part students watch lectures for pragmatic reasons rather than lecture quality.[12] Students do not view recorded lectures as a replacement for attending live lectures, and often continue to attend face to face sessions.[13] Students who use recorded lectures as a supplement sometimes score significantly higher in subsequent assessment.[14]
Some firms may also use lecture recordings as advertising, collaboration, or training materials.[15]
In addition, lecture capture technology may offer compliance, for example with United States legislation such as Section 508 for students with disabilities. In the United Kingdom, under the Equality Act 2010, universities should provide reasonable adjustments. Providing access to lecture recordings may be considered to be such a reasonable adjustment.[16]
Research[edit]
Lecture captures are becoming increasingly popular. Many institutions including University of Manchester, University of Glasgow, University of Bristol and Loughborough University provide guidelines for recording and presentation of lectures which would be useful for learning[17][18][19][20][21][22] and there is a growing literature that considers the benefits of lecture capture to students and tutors, as well as the extent of student usage of lecture recordings.[23][3] Research at Cornell University found increased flexibility for students and faculty.[24]
REC:all (Recording and Augmenting Lectures for Learning) is transnational learning technology project supported by the European Commission under the Life Long Learning Programme, it aims to explore new ways in which lecture capture can become more pedagogically valuable and engaging, and is investigating a variety of learning design, technical and legal issues.

Ruby on Rails 3.0 Release Notes
Rails 3.0 is ponies and rainbows! It's going to cook you dinner and fold your laundry. You're going to wonder how life was ever possible before it arrived. It's the Best Version of Rails We've Ever Done!
But seriously now, it's really good stuff. There are all the good ideas brought over from when the Merb team joined the party and brought a focus on framework agnosticism, slimmer and faster internals, and a handful of tasty APIs. If you're coming to Rails 3.0 from Merb 1.x, you should recognize lots. If you're coming from Rails 2.x, you're going to love it too.
Even if you don't give a hoot about any of our internal cleanups, Rails 3.0 is going to delight. We have a bunch of new features and improved APIs. It's never been a better time to be a Rails developer. Some of the highlights are:
- Brand new router with an emphasis on RESTful declarations
- New Action Mailer API modeled after Action Controller (now without the agonizing pain of sending multipart messages!)
- New Active Record chainable query language built on top of relational algebra
- Unobtrusive JavaScript helpers with drivers for Prototype, jQuery, and more coming (end of inline JS)
- Explicit dependency management with Bundler
On top of all that, we've tried our best to deprecate the old APIs with nice warnings. That means that you can move your existing application to Rails 3 without immediately rewriting all your old code to the latest best practices.
These release notes cover the major upgrades, but don't include every little bug fix and change. Rails 3.0 consists of almost 4,000 commits by more than 250 authors! If you want to see everything, check out the list of commits in the main Rails repository on GitHub.
