Linear motion

Image
As per notes made January 2018, I shifted back to using meters for the RipStik linear motion exercise to simplify Desmos data entry. Prior to class I measured out a 30 meter run with timing marks every three meters. I also set up a Desmos table with the distance data, leaving the time cells blank.


This pre-class work was even more necessary fall 2018 as the class periods are now 50 minutes long, as opposed to 55 minutes as they were last term. I had to go over the Friday quiz and then move out to the sidewalk to gather data. I prefaced the sidewalk work with a speed calculation from Friday's long run: 15015 meters ÷ 6000 seconds = 2.50 meters per second. I do not know that this helped as an introduction to speed.



The run ended at 15.78 seconds and 30 meters. As seen on the graph, the slope displays well on a "square" graph, something that was not the case when the distance was in centimeters.


Wednesday I demonstrated Desmos on the television monitor at the back of A101 u…

Banana patch clean-up

The third day of ethnobotany class is, as was the second day of class, spent out in the field, again with machetes, again whacking away at various invasive species.

Beginnings with the density of soap

Image
Beginnings are perhaps the single most important moment in a relationship. The complication with starting off day one with a community building exercise in a collegiate class - unlike the scenes shown in movies - is add/drop. For the first three days the class role is an unstable and shifting field of play, with students appearing on and disappearing from the role. Last spring I had opted to do an introduction to physical science and that the mathematics underneath a system explains the system - juggling stationary versus juggling on a RipStik produced parabolic arcs of different widths to an external observer, but the quadratic nature of the mathematics remains the same.

Introducing the tech stack in SC 130 Physical Science
Fall 2018, however, featured new 50 minutes class periods (class periods have been 55 minutes since I came on board in 1992) and a longer mathematics pre-assessment that included a look at inferential science skills. There was still the requirement to be met of int…

Mars and Murrie Milk Chocolate Statistics

Image
For a fifth term the MS 150 Statistics course began with a problem solving open data exploration leading to a presentation. The exercise effectively flips the role of the students from that of being students in a class to that of being statisticians reporting on their statistical findings. This shift allows the instructor to begin the second week of class by saying, "I know you already know how to calculate statistics and make charts..." This gives the students an early sense of success and a sense that they can succeed in the course.

Students starting work on their MMs
For fifteen years the statistics course started with gathering data on body metrics and then launching into a lecture driven course. In 2008 I added statistics projects to the lecture and test mix in an attempt to both increase student engagement with statistics and to integrate more writing into the course. The statistics projects did not result in increased student engagement with statistics.

In 2013 the exp…

Ethnogardening

The second day of class the ethnobotany course tended to one of the plant collections scattered around the campus. Some of the plants in the area the class worked include Senna alata, a variety of Ixora casei, Jasminum sambac, Macaranga carolinensis, Gardenia jasminoides, Cymbopogon citratus, and Myristica fragrans.

College summit on student advising

Image
The summit was opened by the acting Vice President for Institutional Effectiveness and Quality Assurance followed by opening remarks by the president.


This summit focuses on advising and improving advising in support of student success. The Vice President for Instructional Affairs covered some of the curricular innovations engaged in last year including the use of compressed schedules, embedded tutoring, and teaming up a developmental reading course and the general education history of Micronesia requirement. Pacific Resources for Education and Learning provided support for bringing in a filmmaker in support of the reading course and the history of Micronesia course.

Vice President for Enrollment Management and Student Services. 1505 students sat the COMET entrance evaluation tool. 1299 were seniors. 78% placed into programs, 22% were not able to be admitted. 25% of the admitted seniors were placed into college level courses, 75% were placed into developmental course programs.
