This course demonstrates how to use the new logging feature in swirl with Google Forms. This is a simple way for course instructors to monitor how their students are performing in swirl courses.

# install.packages("swirl")
library(swirl)
install_course_github("seankross", "Google_Forms_Course")
swirl()

Follow these steps in order to set up a Google Form that can collect student's swirl progress:

1. Create a new form by clicking "New" on https://drive.google.com
2. Name your form something memorable.
3. Your form should have only one question which should be a paragraph type question.
4. In the upper right corner of the form there should be three vertical white dots. Click on that icon and then click "Get pre-filled link." This will open a new window.
5. Click "Submit" and copy the generated link.
6. Paste the generated link into customTests.R where indicated, so that a string containing the link is assigned to the pre_fill_link variable in the function submit_log().

• swirl logging is disabled by default. Add the line swirl_options(swirl_logging = TRUE) to initLesson.R in order to enable logging.
• Copy my customTest.R file and edit the assignment of pre_fill_link as described above.
• The last question of the lesson should look very similar to the last question in this lesson.yaml. Of course you should feel free to edit the output.
• dependson.txt must at least contain base64enc.

1. Install swirlify. You must use a version of swirlify later than 0.4.1.
2. Download the csv results from Google Forms.
3. Run swirlify::google_form_decode() and select the csv you downloaded.
4. google_form_decode() will return a data frame containing how each of your students performed on every question.
