Return rates on student evaluations of instructor, course, and course materials have been low. The evaluations are anonymous to encourage respondents to respond honestly without fear of retribution. With thanks to a colleague for the following concept, the following is one way to encourage return of evaluations. The concept is to have students submit a screenshot of the evaluation header for credit. The following directions were given for the assignment: Upload a screenshot of the student evaluation header image after completing the evaluation. Just the header image. This is an example header from the summer 2022 course evaluation. You are to submit an image of the current header. Do not include answers to questions in the screenshot! After you finish the evaluation, submit the header image so that I will know you completed the evaluation. The evaluation is available at: [redacted] Course prefix, number, and section: MS 150/O1 Course name: Statistics Instructor last name: Lee Ling Inst...

Tabular data in Desmos is not directly exportable in any form, nor is there a way to copy and paste the data in a Desmos table.  A screenshot of the table was uploaded into Google Gemini with the direction to convert table image to a spreadsheet format. Gemini returned a comma separated list. That list was copied and was pasted into a text editor. The text editor was used to save the file as a comma separated list (.csv) and then imported into a spreadsheet for analysis of frequency versus the speed of sound. 

Monday the Limits of Light posted by Go Wild was used to introduce the connection between colors and wavelengths along with the general notion of the electromagnetic spectrum. Wednesday cold opened with a video titled Indigo by Indonesian singer-songwriter Nicole "Niki" Zefanya  No one paid any attention to the cold open. I asked the class what the video was about, but no one had watched the video. One student did eventually hit on "blue" as the theme. I then pivoted to the spectrum boxes. The students saw six colors. No one had any issue with that determination. I used this to suggest that in order to understand the science of a particular period one has to understand the cultural understandings of that age. No one caught the six reference.  Once I made the explicit connection I moved on to seven days in a week, seven musical notes in an octave, seven visible moving objects in the Newtonian night sky, seven Platonic solids, and the sevens in Newton...

Class opened with the course evaluation. On account of the course evaluation the first few videos were dropped from the playlist . The playlist cannot be moved to the edu account: the video  Sexual Reproduction in Flowering Plants by It's AumSum Time was changed to content made for kids and can no longer be added to playlists. The video remains available in the legacy playlist but cannot be added to a new list.  A song by Blackbriar called Floriography was added. There were a number of floriography videos, but all were seven to fifteen minute deep dives into the complexity of floriography. Whenever a system is that complex, with flexible multiple meanings for any one given flower given the rest of the bouquet, then there is clearly a high risk of miscommunication. I think the books on floriography were more popular than the actual floriography. In any cased the videos were tangential to the meanings cited in the assignment which are based on single colors. Students are instru...

The class started a few minutes late at 11:03. The video playlist began at 11:10 and ran past 11:50. A new video was an update on the coconut rhinoceros beetle update from Hawaii.  The invasive species presentation followed. The slide from iNaturalist was copied over to the invasive species presentation. Wrap was around 12:30. The laboratory often includes a walk and talk element, but today that was dropped - the campus is still a construction zone and the invasives have been touched on during earlier walk and talks. 

On rainy days physical science laboratory ten, which measures the speed of sound, is done using resonance tubes and tuning forks. On days without rain the laboratory is done outside by timing the delay between seeing two-by-fours clap and hearing the clap across distances ranging from 300 to 500 meters. The class does one or the other, but never both. This term the class performed the indoor resonance tube version of the laboratory. A laboratory report was submitted that mentioned having done both versions of the lab and included vocabulary never mentioned in class. This suggested that the student may have copied and pasted the entire directions into a large language model system, neglecting to delete the outdoor version of the laboratory from the input. The following looks at what happens when raw data, a graph, and directions without editing are uploaded into a large language model, ChatGPT. Screenshots of the data table and graph were uploaded into ChatGPT 4.0 mini. ...

With the near equatorial trough rebuilding across eastern Micronesia, rain heavy enough for a flash flood warning was coming down.  The water, however, was off at the college. On a day when the indoor version of the lab requires a lot of water. The above technique worked the best. Erlenmeyer flasks were a flat oil fail along the stop line due to wind and standing water. They floated unstably and keeled over with the next round gust. These proved to be able water catchers and provided a sufficient source of water for the lab. The students would need all of the tall graduated cylinders as water storage for each group. Each group needed a resonance tube and a water storage tube. This term the meters sticks were not forgotten. Aimee and Valerina  The Erlenmeyer flasks were noted to be too noisy in the past and that proved true again this term. The spout on a beaker permits more pouring control, including pouring o...

Sinae presented a coconut cup. A general use coconut cup is known in Pohnpeian as pohndal. If the intended use is to hold and serve sakau (Piper methysticum) then the cup is referred to as ngarangar. A ngarangar cannot be used for anything other than sakau. Once sakau is in the cup the cup is referred to as kohwa. In the nahs (traditional structure) there is one kohwa per pounding stone (peitehl). The cup is shared: around the cup every is treated equitably. Not that everyone is equal, but everyone is joined by the cup. The cup is passed down through the generations. Thus the cup unites those who are present with each other and unites those who are present with the ancestors who have gone before. There is a rich symbolism in the kohwa and the kohwa is treated with great respect. The Pohnpeian pwaht (English: plate). This is intended as a coconut leaf plate to hold food for an individual. These were probably developed post-contact, hence the name deriving from En...
