Latitude and longitude

Image
Coverage of latitude and longitude began on Monday with a globe and an introduction to latitude and longitude on the planet earth. This term I did not focus on what is at the prime meridian at North 6° 54' and this would play out as dropping the Ghana angle. This would work well on Thursday as this term the classes did not return to A101 after taking data. Data was analyzed in the field with the aid of the new Tripltek tablet. Wednesday hide and seek returned to N 06° 54.646' E 158° 09.432' (N 06.910760 E 158.157188) behind the IT shop.  Reagan, Kamaloni, Alexander, and Sean arrived at the hide at 12:22. The location works to demonstrate the concept without requiring wading through the paddle grass to find me.  Reagan and Sean used a GPS, Alexander used an app on his phone. A second group arrived at 12:26 led by Myena and and Fredson. Kiora was also holding a GPS but did not appear to be actively navigating. Joe Scott and Malisa were with this group. Myena checks the accura...

Data exploration two and histogram submission issues

Image
Data exploration two heart rate data is done as a spreadsheet submission in MS 150 Statistics.  The complication is that upon submission to Instructure Canvas LMS from Google Sheets, the histogram disappears. A suboptimal solution is to have the students submit a screenshot. This assignment should be rebuilt back around being submitting as a presentation rather than a spreadsheet. A video that closely mirrors the exploration should be developed and deployed. 

Food of Micronesia

Image
Students in the ethnobotany class reported some of the foods of Micronesia. Koahp pirain, fried yam, was presented by Aleina, RJ, Reagan, and Joymar. Aleina gave the presentation Joymar, Reagan, Aleina, and RJ Rindy presented wa-fÄ“tún a dish prepared by scraping banana out of the skin, cutting the banana into pieces, and then putting the banana back into the skin to cook the banana. Coconut cream is then added to the top. The difference from the Pohnpeian koroipali dish is that for wa-fÄ“tún the whole banana is cut into pieces. The Pohnpeian version leaves a longitudinal half of the banana in the peel. Supporting Rindy were Ladricia, Laninette, and Twindon. wa-fÄ“tún Bulage/Bunafat: boiled giant swamp taro presented by Twindon Enoch and Tommy presenting mai sukusuk Tino and Reggie presented outer island Yap mwaa: pounded, fermented breadfruit. The process includes rinsing resulting in a milder flavor. This dish is a traditional staple on Ulithi. Kraka mwangas: carmelized coconut cand...

Relative frequency is probability

Image
 Thirteen students tossed a coin ten times and counted the number of heads obtained. The results were recorded on the whiteboard. Note that the mode is "five heads" and not one or zero in the second column: those are frequencies. The most frequent result was five heads. The above spreadsheet is the same data as on the whiteboard. The relative frequencies are the probabilities. Expand the sample size to 1000 students tossing a coin ten times and here is one of the relative frequency results obtained.  Expand the sample size again, to infinity and beyond, and one will eventually arrive at the mathematically predicted outcome for ten tosses of a coin. 0.25 or 25% of the tosses will be five heads. 21% will be either four or six heads. Zero, one, nine, and ten heads are very rare. This distinction between what is randomly expected to occur (three, four, five, six, and seven heads account of 89% of the expected results) and what is rarely expected to occur will underpin work on wh...

Canvas analytics week 06 fall 2022

Image
Engagement on the Instructure Canvas platform as measured by the average number of page views per day of the week has had the same pattern for four terms: Monday to Thursday see the highest level of engagement, Friday is always down slightly, and Saturday and Sunday are greatly reduced. That Sunday exceeds Saturday may in part be a result of the availability of campus learning resource center computers on Sundays. The chart provides indirect evidence for students who note that assignments due on a weekend are problematic for them. On a weekend families often expect their students their engage in and support family activities. As one father once said to me, "You get my son from Monday to Friday, I get him on the weekend."  On a logarithmic y-axis, engagement from week four to five remained relatively stable. This chart trails the current week by one week as these reports are done before a week is over. Canvas analytics displays 1938 students are on the platform in week six. Th...
