Teachers should not fear open-source technologies. Many mistakenly believe that education technologies are expensive and complicated to use. Open-source technologies are stable, secure, and compatible with other platforms. Organizations both small and large use open source devices every day. Many businesses use open-source servers for their efficiency and costs savings. They often have large communities that provide high quality customer support. Best of all, open-source technologies often cost less than proprietary products.
One of the 5 steps is don't fear technology. Technology is expanding and as future teachers we have to keep up to date with it so that we can use it instead of fearing it.
