Comment Flawed study -- grade inflation (Score 1) 273

Full disclosure: I did not pay to read the article. Based on the summary, there are some pretty outstanding flaws. Also, I have not received tenure yet (but will be up for tenure soon). I do spend quite a lot of time off-the-clock (i.e. anywhere not on campus) focusing on how to improve my teaching. I also feel that I am more enthused than some of my older, tenured counterparts. I teach both lower level courses as well as graduate courses. That said, 1. Non-tenure faculty tend to teach lower level courses. From a career standpoint, they are more likely to care about students' reactions to their courses because it could reflect poorly on their tenure portfolio. Grade inflation would not be out of the ordinary. If anything, the results of this study confirm my suspicion that there tends to be more grade inflation among non-tenured faculty. Not only does it make students a bit happier, it means these faculties are less likely to get bad reviews from students (and hence less likely to be fired). 2. Tenured faculty tend to teach more advanced courses. Not only is the material more difficult to learn, one may argue it is more difficult to teach (especially if the students are actually not well prepared due to weak foundations from lower level courses).

Comment And if we avoid the middleman altogether? (Score 1) 379

When I was a kid, trading video games was the norm. Sometimes I would just borrow my neighbor's copy of a game. We also skipped the middleman altogether -- there was no used video game stores at the time. If I wanted a game that my friend was willing to sell, any used sales happened between the endusers. I am curious what this would mean for people who still consider swapping games, or borrowing each other's games.

It would appear speaking into Siri or other applications that do speech to text hasn't been studied enough to make a final decision, but I think it's going to end up OK. This study is a piece of garbage though and falls into bad research, as the software wasn't used as intended in the car.

The only valid study would evaluate the software being used as it is typically used, regardless of the manufacturers intent.

Well said.

The research is still valid in the sense that most people probably have no idea about "car mode" and "no-eyes" mode.

Hmmm, seems a little shallow to claim the research is valid when it blames the device for ignorance of the operator.

The real problem is something like 60 or 70% of the people have given up on SIRI all together because it just doesn't work all that well.

Except it doesn't blame the device for the ignorance of the operator. The ignorance of the operator is already a given -- they're texting while driving, or trying to do the equivalent thinking that the way they (mis)use Siri makes it safer to text. That they additionally are ignorant of the different modes only further supports the idea that texting while driving (regardless of how it is done) is generally less safer than not texting. At worst, they would simply need to modify it to say that "the way most people use voice-activated texting is no safer than typing" as opposed to just "voice-activated texting is no safer than typing." I would argue the former is rather redundant.

The research is still valid in the sense that most people probably have no idea about "car mode" and "no-eyes" mode. That said, even if you were to consider only those who are aware of such features as your test subjects, I wonder if the data would be any different (provided the test subjects are not explicitly told they must use no-eyes mode and car-mode). I know that if car-mode and no-eyes mode puts many restrictions on Siri, then (for me), Siri would not be as useful.
