Biomed lab tours and online discussions

I forgot to type up notes after the sixth day of the freshman design seminar, because I had a meeting right afterwards.  I’ll try to make up the deficit now, two days later.

At the beginning of class I collected the homework (which had originally been due Monday, but which I had given an extension on, so that students could do it right).  I’ve not looked at it yet, but I could tell when I collected it that students had taken to heart the message to type up their homework and put some care into it.  I hope that spills over into their other classes—not only will it benefit them, but it will help our department if the bioengineering students get a reputation for being diligent and meticulous.

Most of the class time was spent on lab tours in the Biomed building, given by four grad students who work there.  The tours were good, providing students with some idea what sort of work was being done and what sort of equipment was available for doing the work.  They saw high-temperature incubators for hyperthermophiles, a glovebox for working with anaerobic organisms, a qPCR machine, an ultracentrifuge, a cell sorter, a large warm room (hardly being used—there was one shaker table with one flask, which would easily have fit in a benchtop incubator),  mammalian cell culture facilities, and a teaching microscope for mouse surgery.  (And other stuff that I won’t bother to list here.)

The whole Biomed building seems to be half empty and even the occupied lab bays have a huge amount of space per person, especially compared to the rather cramped labs stuffed with students and researchers that we saw in Baskin a couple of weeks ago, which makes it irksome that the University administration has been preventing our department from doing recruiting for wet-lab faculty for lack of lab space.  All the space is earmarked for growth in a different department, which would take them 10 years to fill (if they ever manage to do so).  The space planning on our campus seems to be done by turf wars between deans with no central rebalancing, and one dean (not ours) now holds all the empty space on campus.  Our dean has an unimproved warehouse 3 miles away which would cost millions to convert into anything usable, even if it made sense to exile active researchers from campus.

The lab tour ran a bit long, and half the class had to leave, but the other half got an interesting discussion about getting into research as an undergrad from a grad student who had been an undergrad here.

The e-mail mailing list for the class is still not serving its function of providing an out-of-class discussion space.  Only eight students have posted anything and no student has responded to another student.  The list is still useful for my making announcement (like when homework has been posted on the web site), but it isn’t working as a discussion forum.  I’m apparently not very good at creating online discussions—I’ve not gotten them to work in classes yet, and even this blog has 86 views for every comment (and 40% of those comments are mine, so the ratio is more like 144 views per external comment).

I looked for some stats on MOOC discussion groups, to see how my online discussion compares with classes that are only on-line.  I found a series of blog posts by Jeffrey Pomerantz where he analyzes the data for a MOOC course he is teaching.  The one about online discussions showed him getting 1787 posts and 707 comments in 8 weeks, for a class whose size was 27623 total registrants, 14130 active students,  9321 video viewers, 2938 who did one homework, or 1418 who completed the course (numbers from his post about course completion).  If we take the video viewers as the most realistic measure of the class size, we get about 3.3% of the students posting or commenting per week.  Maybe my 60% participation in one week is not as bad as I feared, even if it doesn’t have the feel of a discussion yet.

Bus stop shelters

What properties should a bus shelter have?  I can think of several:

  • Shelter from the rain.
  • Shelter from the wind.
  • Good visibility for bus drivers to see people waiting (and for those waiting to see buses coming).
  • Lighting at night for security (and possibly an emergency call box).
  • Bench to sit on.
  • Posted schedule of buses.
  • Maps of area near bus stop.
  • Ample bulletin board space for community announcements.
  • Attractive appearance suitable for neighborhood.

When I first started work on campus, we had great little redwood bus stop shelters at every bus stop, but they started to rot and were all torn down.  The old shelters had all the desirable features except one: they lacked campus maps.

The administrators promised us great new shelters after tearing down the old ones, but “temporarily” got some cheap sheet-metal roofs with no wind shelter and little or no poster space.

Typical prefab bus shelter on campus—this one is deep in the East Remote Parking lot.

The bulletin board space in the new shelters is tiny, and most of it is taken up with permanent official signs:

One new bus shelter was built (at the main parking lot, of course, since motorists are far more important than people who take the bus to campus). It was bigger and better looking than the prefabs, but still had no wind shelter and only minimal bulletin-board space.  This used up the bus shelter budget, and subsequently only the prefab units were used.

Large bus shelter at the East Remote Parking Lot, the only custom bus shelter on campus.

Many of the newer bus stops, which serve far more bus riders than the palace at the parking lot, don’t even get a wide space on the sidewalk. In fact, the road was widened so that stopped buses can pull completely out of the lane, so that car drivers are not delayed, while the sidewalk gets so jammed with people waiting to board the bus that pedestrians cannot get through.  One of the worst such places (in front of College 9) is shown here during the summer, when no one is around:

College 9 bus stop that causes serious pedestrian congestion.

Some of the busiest bus stops on campus don’t rate a shelter:

The Health Services bus stop doesn't get a shelter or a widened sidewalk, but does have benches.

One of the busiest on campus doesn’t have any amenities:

The only amenity for the Science Hill bus stop is a trash can. Even the signage is temporary.

There is one bus shelter on campus where widening was done to put in the bus stop, when the campus decided to have the buses go both ways around campus, rather than always counterclockwise (more on that decision in some later post).

Bus stop on a deck—the only place widening was done to make room for a bus shelter.

Overall, the bus stops on campus are dismal designs, failing on all design points except rain shelter, posted bus schedules, and lighting. Several of the bus stops manage only the bus schedules and the lighting.
