The subject matter being obvious and well understood can look a lot like the subject matter having no meaning at all because the learners are completely lost.
Particularly, asking 'any questions?' and then moving on (often rapidly) when no questions are forthcoming is another sign. It's hard to tell if it is because there is full understanding or almost no understanding. Instead, try giving more time for people to think of questions, and ask 'what questions do you have?'.
I've not had a chance to try, but in a similar vein, having an IRC chat running along side a lecture could provide similar useful feedback, and an avenue for questions without making learners feel stupid.
I like the direction they are taking with this tool. Good, honest, and especially timely feedback is one of the difficult challenges of education. Without it you are flying blind.
If it also included metrics on improvement in understanding over time and across instructors it'd be even more powerful.
ClassMetric actually started as Bookxor, where the focus was on document analytics and discussions. We showed teachers which pages students were reading and how long they spent on each page. The system also let students post questions and have discussions in the margins of the document.
Over the next couple months we'll be bringing some of these ideas back to ClassMetric. Maybe these document-centric features would be more useful for you?
The comment isn't particularly insightful. It espouses your opinion (totally OK) without any reason or rationale (not OK). Why is it better? What could this company learn from Learning Catalytic's product? Is this just observation, or are you uniquely qualified to judge these two products?
The link is completely superfluous. It goes to a login page and doesn't tell me anything about the company or product. Also, a note on style, links are typically just left inline http://google.com or in parens (http://google.com) but that's orthogonal to what matters - insightful comments.
I hope that's helpful!
ClassMetric is intended to require very little additional effort from the professor, but still give them good feedback. ClassMetric's discussion system is very much in the spirit of Mazur's peer instruction. Students often answer each other's questions on ClassMetric.
LearningCatalytics and ClassMetric are different, but we'll definitely learn from Mazur's research. Thanks for the link.
A PSUN is a Personal Sockpuppet Upvoting Network, which is a bunch of Amazon EC instances masquerading as human HN users, programmed to immediately upvote submissions and/or comments made by the owner of the PSUN. They're getting more clever at it too, by posting vapid marketing one-liners to bump the comment count.
Some PSUNs are really elaborate with precisely emulating a human traffic pattern, reading comments, up/downvoting here and there (triggered by textual analysis of comments), and therefore impossible to distinguish from a real human user, even with social graph analysis.
Like Windows can't do with a Anti-Virus program, HNers who don't want to see every submission they make slide into oblivion, are required to deploy a PSUN.
I am one of classmetrics founder's brother, and run my own company out in Philadelphia area called LeanServer.
If you need my papers, I will be more than happy to fax them to you.
In which case, although you may not be a sockpuppet in the literal sense, what you did is frankly not much better. Sorry to be the bearer of disagreeable news, but that's how it is.
It's not just that you'll get downvotes for this. I don't know about anyone else, but my opinion of the likely value of ClassMetrics went down when I saw your comment, and further down when it was confirmed that you were indeed basically spamming HN. That's probably not the outcome you were looking for.
[EDITED to fix a typo.]
no need for papers, I'm not the Internet police. :-P
It's just that your first comment came across as very suspicious, aside from not adding much to the discussion.
Even having established that it's not a sock puppet account per se, it is still convention around here to disclose affiliation (anonymously praising your brother's company qualifies for this).
Anyway, welcome to HN and best of luck with your startups to both of you.
The attitude here is "Add value, or get downvoted."
To be honest, I've seen that sometimes people get downvoted anyway, but that's life.
