2. @GregKapfhammer www.gregorykapfhammer.com Hi! My name is GREGORY M. KAPFHAMMER
3. Ask and answer questions about effective instruction in the programming field Roadmap for this Talk
4. GitHub Travis Python Exploring Technologies
5. GitHub
6. Travis
7. Python
8. DECIDE TO USE GITHUB AND TRAVIS CI? Why would I
9. Clear Status Key Ideas Fast Grading Important Goals
10. HELP STUDENTS AND FACULTY EFFECTIVELY COLLABORATE
11. Source Code Technical Writing Commit Counts Commit Messages Program Output Data Files Deliverables to Check
12. USE INDUSTRY STANDARD TOOLS IN ALL COURSE WORK
13. DEVELOP NEW SOLUTIONS IN PYTHON WHEN NECESSARY
14. Tools Options Testing Benefits of Python
15. SETUP AND USE GITHUB CLASSROOM? How should I
16. Create a GitHub organization for your course
17. Now you have an empty organization
18. Let GitHub Classroom access the organization
19. Create a student roster for the Classroom
20. Create an assignment for your course
21. CREATE TWO REPOSITORIES FOR EACH ASSIGNMENT
22. Solution Starter Check Using Travis CI
23. THE STARTER REPOSITORY SHOULD NOT PASS THE TESTS
24. Create an assignment using the starter
25. A classroom will contain many assignments
26. AUTOMATICALLY CHECK STUDENT SUBMISSIONS? How do you
27. Local Travis Flexible Checking
28. Use Java and Python 1. # use both Python and Java 2. sudo: required 3. dist: trusty 4. language: python 5. python: 6. - '3.6' 7. before_install: 8. - jdk_switcher use oraclejdk8 9 Java is the main language for this course
29. Decide if Check Passes 10. determine_exit_code() { 11. if [ "$1" -eq 1 ]; then 12. GATORGRADER_EXIT=1 13. else 14. if [ "$2" ]; then 15. echo "$2 was successful" 1. #!/bin/bash 2. 3. # assume that gatorgrader.py exits correctly 4. GATORGRADER_EXIT=0 5. 6. # assume that the human-readable answer is "No" 7. GATORGRADER_EXIT_HUMAN_PASS="No" 8. 9. # determine if the exit code is always failing The build passes if all of the checks pass

35. This approach ensures that the source code and GitHub repositories are organized. It is easier for me to help the students who are struggling in an introductory course. - SAEJIN MAHLAU-HEINERT
36. This tool suite made it easier for me to talk with students about technical requirements. It helped me to make complex assignments more accessible to students. - MARIA KIM
37. GatorGrader encouraged me to add better code comments and try out language constructs that I would not have otherwise investigated. The tool was a big help this semester! - SAMATHA DARRIS
38. GatorGrader is like having a constant coach! I liked receiving feedback on the quality of my source code and writing before turning in the final version of my lab. - ANNA YEAGER
39. IMPROVE AND STUDY THIS APPROACH? How can we
