Rocks

This laboratory has two separate goals. 
  • To learn how rocks are characterized
  • To learn to build a slide deck using mobile apps
Questions to be explored in the laboratory:
  • What are the three basic types of rocks?
  • What is rock hardness?
  • What is rock luster?
  • What is rock breakage?
  • What is rock color streak?
  • What is the identification of your rock?
On Pohnpei there are essentially two types of rocks. The black colored rock is basalt, a combination of minerals produced by the volcanic eruptions that formed the island. Basalt can be composed of different minerals. Basalt on Pohnpei contains iron which oxidizes to form red and brown colors. The red clay soils are also high in iron. There is so much iron in the ground that well water in some places has too much iron to be consumed by us. Out in Nett there is a special facility that removes iron from the well water.

The other type of rock is coral, usually a white color. Coral is not a mineral because the origin of coral is in a living animal, coral polyps.

The first goal of this laboratory is to explore rock characteristics for five rocks. Pick out five rocks and for each of those five rocks engage in the following explorations.

Veronica and Youlanae Maiea photograph their five rocks

Grace Marie researching a rock and Bracey studying her selections

Aquillera looking up rock information

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...

From Canvas to Moodle

Migration  There is no option to migrate from Instructure Canvas to Moodle by exporting courses from Canvas and importing those courses into Moodle. Canvas exports courses as Instructional Management Systems Common Cartridge version 1.1 files. Moodle only imports IMS Common Cartridge 1.0 files. The versions are incompatible and as far as this author is aware there are no converters between the versions.  IMSCC 1.0 is a 2008 standard and IMSCC 1.1 dates back to 2011 or earlier. In other words, both versions are out of date. The current version is IMSCC 1.3 and IMSCC 1.4 is under development. Neither Instructure nor Moodle appear to be working on code to handle any newer IMS CC version. The inability to easily move courses between learning management systems benefits vendor lock in.  As a result, migration is a heavy lift manual process of rebuilding element-by-element from a blank sheet. Or one can pay a third party significant sums of money to handle the migration. T...
