You can create text OERs in the word processing application of your choice. LibreOffice (below) is a suite that includes a word processing application and a PDF editor
You can save your OER inin any document format that doesn't require proprietary software to edit. PDFs are generally ideal for text OER.
You can also create a document in odt format (the open format version of .doc or .docx, which is proprietary to Microsoft) or create an HTML web page.
Smartphones come with a camera that is perfectly adequate for most picture taking purposes. You'll only need something fancier if you want to take pictures at the telescopic or microscopic scale.
You'll need an image editor application to crop, apply filters, add arrows and text, and otherwise edit your photographs. You can also create images from scratch in your image editor.
Here are some free image editors available on the web:
Creating basic audio files will require a microphone, probably a better one than the one that came built into your laptop. The one that is built into ITS's standard issue webcam is fine for most non-musical purposes.
If you are recording music or other sounds that require higher fidelity, talk to a sound technician. If you can't find one among your colleagues, you can ask at a local guitar store or community theater group. Expect to have to pay, and be very clear about your goals, timeline, and budget.
You'll also need audio editing software:
It's ok to keep copies of your OER in your course, but that should not be the only place. Learning Management Systems like Moodle don't allow public access and aren't set up for organization and searching that way.
You may need to provide access in three ways:
Some educational institutions have streaming servers for audio and video, as well as space for faculty to store files.
SUNY Empire has LEARNscape for multimedia resources.
If your institution doesn't provide a streaming server and storage space, you can host your multimedia files in the cloud. The "cloud" means storing and processing data on networked facilities (computers somewhere on the Internet) rather than locally on your own computer.
Currently the best free option for hosting images in the cloud is:
Here are several free options for hosting audio in the cloud:
iTunes isn't listed here because it is only a directory service for podcasts; it doesn't host them. See iTunes: "making a podcast" for more information on RSS feeds (the way the ITunes store generates podcast listings.)
And remember to always submit your OER to be included in MERLOT so that it can be found by other educators!
Not all of these tools are open source, but they do output open file formats. They vary in terms of accessibility. They are certainly an imperfect set, so if you have better suggestions, please contact sarah.morehouse@sunyempire.edu.
