4.1 4.2 RipStik run

The RipStik run returned to the covered walkway after testing out the new health center fall 2025 and the unfinished student center spring 2026. An 81 meter run from LRC to the A building was laid out. This was a cold open on the sidewalk with a note to students ahead of class to meet on the sidewalk. This saved significant time. Initial roll was called on the sidewalk.

O meters was at the LRC. 


Every three Meyers was marked out to 33 meters in front of faculty office.



51 meters at the junction.

71 at the turn

81 at the A building. Spreadsheet and Desmos were prepared in advance.


The layout worked well to illustrate the linearity present in the first 33 meters. The gaps to 51m, 71, and 81 meters provided a chance for interpolation. This also was very functional when riding the RipStik. the segment into 51 meters allowed for setting up for the slope into 71 meters. Speed increased to 2.25 meters per second or faster from around 1.54 meters per second at 51 meters. Despite the velocity variation, the data is strongly linear. The variation in speed is useful to begin to dissuade the students from thinking the data must be exactly linear.


The loss in words per day chart was displayed as an example of how even highly variable data gets modeled with linear regressions.

A demonstration of the generating the scatter graph on mobile was done using the Samsung Active5 tablet. Then a demonstration of submission of the assignment from the Google drive was done on the Smartboard. Anecdotally a number of students were unaware of the direct submission path from Google Drive to Moodle.

Moodle bulk grading of manually marked quiz and test questions

Image
Manual marking of an essay type question on a quiz or test in Moodle can be done student by student but that process involves a lot of clicking and scrolling as one has to open each student's submission. There is a bulk marking screen available. In the test or quiz click on Results. At the upper left side is a stealth drop down list menu under the word "Grades" that includes the option "Manual grading." Choose manual grading. On the far right click on the blue "grade all" hyperlink. That will open up a all of the submissions for question one on a single page. One can now mark all of the question one submissions manually for all students in the course.

Experimenting with the PlantNet and iNaturalist apps

Image
The application of image recognition technologies as the back end to botany apps is providing increasingly relevant search results. Over the recent winter break I began looking at whether the apps now available might be useful to the ethnobotany class here on Pohnpei. Some apps had a more regional focus in the past and were better at north american or european plants. Pohnpei has a both unique indigenous plants and many introduced plants from around the world -  a challenging environment for any image recognition system. A student working with a plant identification app for the first time My criterion was that the app had to be appropriate for use in my classroom. The app could not contain advertising and the app had to be free, my students typically do not have the ability to pay for an app. The app would also have to be fairly small as my students often use phones with limited memory and processing power. I settled on PlantNet and was impressed with the ability of the a...

Traditional food dishes of Micronesia

Image
Clara, Jennette, and Joanie presented ground hard taro cooked in an umw, effectively a hot rock oven. Pohnpeian: rotama. Pingelapese: sero. Mwoakillese: rodma. Mortlockese: Amahd. Kosrae: rodoma. After cooking in an umw the rotama is pounded with the petiole of a palm frond. Rotama is made from hard or swamp taro, known as mwahng on Pohnpei, mweian on Pingalap, pula in Mortlockese, and pahsruhk on Kosrae. In traditional times on the outer islands the women had primary responsibility for tending the taro while the men handled fishing and climbing tasks. Joesen and Noeleen presented fermented breadfruit from the outer islands of Yap such as Woleai and Eauripik. The raw ingredients were actually brought in from Yap, Noeleen prepared the maare.  The leaf wrap is ti leaf - Cordyline fruticosa. Pauleen, Barnson, Trisha, Verginia, Con-ray, and Maylanda from Kitti, Pohnpei brought in mahi umw, koahpnoair koakihr, and uht sukusuk. Above is breadfruit umw, mahi umw, o...
