Pohnpei campus open house

Image
Pohnpei campus held an open house for programs on the their campus. In the automotive area a student explains the inner workings of a transmission to a group of off-camera high school students.  Over in the RAC area my son observes a circuit.  My daughter was not as excited as I to get to see all of the inner workings of a refrigerator.  The cabinetry program displayed furniture that they made. The hospitality program had the kitchen in operation, students preparing sample foods for visitors. The front desk for the mock hotel.  The facility also includes a mock hotel room. Students in the agriculture program were giving tours of the traditional plants of Pohnpei garden.  My two touring the garden, still eating their food sample from the hospitality program.

Laboratory fifteen in physical science sought to push the boundaries on the mathematical box for the students.  In   laboratory one   a quote from Freeman Dyson was used to start a journey through the mathematical models  that explain physical systems. Dyson calculated how an electron ought to behave. Later someone went into a laboratory and the electron behaved as predicted by the mathematical model.  Annalyn juggled from first try In   laboratory two   a linear model predicted the location of a rolling ball. In  laboratory three   a falling ball obeyed a quadratic mathematical relationship. The behavior of a   marble rolling off of a banana leaf   obeyed a square root relationship. And in   laboratory four   the marbles knew what to do in order to mathematically conserve momentum.   Sound , the   relative depth of an image , and   Ohm's law   all exhibited linear relationships. Jermis dressed for success There are other mathematical relationships that govern physical s

Dark Curse: Clidemia hirta

Image
Clidemia hirta , known in English as Koster's curse, and locally named riahpen rot (dark curse) continues to spread in the forest across the road from the college. This term twenty-five of the twenty-eight SC/SS 115 Ethnobotany class students turned out to pull Clidemia hirta. Only the delegation from Yap was curiously absent. Anthony launches into pulling a clump that is more than head high The morning was ominous. While Pohnpei is rainy, lightning and thunder are rare. During the morning thundered boomed out across the open spaces of the campus. While thunderheads are rare on Pohnpei, apparently not on the day the class pulls Clidemia hirta. Fall 2010 a thunderstorm crossed campus that same afternoon that six students opted to pull the dark curse. New plants spreading to the west of the original clumps The hike into the dark, wet, muddy forest on a rainy day that had heard thunder earlier in the afternoon. The class first visited the Palikir Ethnobotanical Learning gard

Writing improvement in physical science

Image
In the terms prior to spring 2011 students in SC 130 Physical Science wrote thirteen laboratory reports complete with an introduction, equipment list, procedure, data tables, data chart, analysis, and conclusion. The intent was to put writing into the core of the physical science curriculum . Small but significant gains were seen in writing skills as measured by a rubric . Thirteen laboratory reports in a sixteen week term effectively means marking thirty-two laboratory reports each and every weekend. Marking includes content, grammar, vocabulary, organization, and cohesion. The work load   demanded of the instructor meant that time for work on other courses was limited. Writing was improving, but the intensity of the course was draining. Spring 2011 I decided to experiment with having students only turn in the odd laboratory reports, dropping the number of marked reports to seven during spring 2011. The obvious question was whether gains would still be seen in writing as measur

Good Friday Service

Image
The Women's Christian Association of the Kosrae Congregational Church in Kolonia, Pohnpei, held their traditional Good Friday "black-out" service. Opening with a prayer, the lights are then turned out. In the darkness passages are read from the final moments of Jesus on the cross. With each passage a candle is lit and placed under the cross. I know enough not to shoot with a flash during a black-out service, but others did not. On one of my long time exposures a flash went off. The FujiFilm XP30 handled the sudden illumination with aplomb. Shrue returns from placing her candle in the above image. The service concluded with a prayer and a chance to greet each other at the start of the Easter weekend.

Statistics projects of interest

Each term there are a few student statistics projects of interest. Data samples are usually convenience samples, hence extrapolation is problematic. At best these provide anecdotal glimpses into the system being studied. The students are in their first and probably their only statistics course - an introduction to statistics. Four of the seventy reports contained data that I found interesting. One student studied alcohol sales at a small family owned and operated local neighborhood store. The student found that 53% of their sales was of the highest proof alcohol available in the store. The top seller was not the cheapest of the high proof alcohols, just the strongest. Coupled with their own knowledge of their neighborhood, the student concluded that purchasers were "most likely drinking to get drunk, not drinking for flavor or an addition to a meal." In a related vein, another student looking at cigarette sales in a local family store found that the top seller garnered 55
