1. Virtual office hours. We used Moodle Chat, but I would use the analogous tool on Blackboard, which is the LMS of choice where I teach.
2. Guest Speakers. Skype would be a tool that can be used to bring a guest speaker into an online classroom.
3. Collaboration: I encourage the use Blackboard Collaborate for any synchronous group work. The current downside is the need for the instructor reserve time due to limited licenses. Google Hangouts could be an alternative in this case.
I currently use Blackboard Discussion Forums and email for Asynchronous
communication. Discussion forums are for substantive reflection on subject matter, guided by rubrics. Email is for announcements and one-on-one communication.
I would not use texting in my courses in the near future. Sufficient communication means currently exist: LMS, email, office (face-to-face), telephone, social media.
Polling could be used with a student response system (clickers). We have access to Turning Point clickers. I found this link to be worth investigating after this class http://www.turningtechnologies.com/polling-solutions/turningpoint.
I would not make this a required tool in the near future. The LMS provides sufficient ways to share information for now.
