Thinking dissertation

My advisor thinks I'll be ready to do my comprehensive exams sometime next semester. Sounds absolutely terrifying to me. But I am starting to think about narrowing down my topic for my dissertation, which will inform me better for my comps articles. Big sigh. This is going to be hard. Anyway, there are just too many things to do, and I am having a hard time choosing. But a quite prominent professor here on USU's campus told me that the best dissertation is a finished one. And he is right. I am not going to change the world with my dissertation. So I'm thinking there are several problem-based learning areas I could focus on, online educational resources quality, or institutional repositories. Ah! Way too broad.

Clarifying face to face class meeting

I need to clarify what I had written in a previous post . David had made a comment to me that my question showed, "a pretty pervasive bias toward knowing "like we do offline", and that knowing should always be like that. I think we should recognize the legitimacy of completely online relationships...". After reading his comment I realized that I had not written or conveyed in my writing very well what I was really thinking. I do that so much. So, I am trying to redeem myself in some ways because I love online learning and interactions, and I guess I don't want people who read my blog to think that I believe online interactions and learning should be like face-to-face. I realize it is different, and I actually appreciate the difference. In my personal experience with online vs. face-to-face I have noticed though that the online relationship changes some once you've met face-to-face. That change usually isn't bad. So back to my original post about the ...

Moo Y'all

I have mixed feelings about this weeks assignment. I really enjoyed the time I spent in Zork playing. I remember my older brothers playing games like this when I was younder. I would watch them type in commands and then map out on paper where they were. It was fascinating. The hours of playing in Zork were fun. I found that for that sort of game I loved to explore the world and try to map out where I had been, like I had seen my brothers do. I found it hard to navigate the game without mapping. LambdaMoo was a different story. I never had problems connecting with the server, but I had problems once inside the world. It took me quite a bit of time to grasp the commands. In the mean time the other people in the rooms with me laughed at me, jeered. At one time someone had mentioned that they were new (like me) and that they were a student. Someone who obviously was well known to the world said, "No one is holding class here. We're a small community that really resents untrain...

Open Ed - Week 2

The reading this week Giving Knowledge for Free: The Emergence of Open Educational Resources brought out some good points for me. This is certainly something I'm going to need to read a couple of times to pull out all the useful information for myself and my work. The first point that caught my eye said, "OER projects can expand access to learning for everyone, but most of all for non-traditional groups of students, and thus widen participation in higher education. They can be an efficient way of promoting lifelong learning, both for individuals and for government, and can bridge the gap between non-formal, informal, and formal learning." I hadn't really thought of OER's doing all of that. Of course I knew that an OER is great for expanding dissemination of a resource and/or the information in that resource, but the lifelong learning point hits home to me since that area of research interests me and fits right into an idea I am researching at this moment, problem...
