About
Introduction
  • School 21 methodology only makes sense if peer-to-peer reviews are taken seriously. Please read all the guidelines carefully before starting the review.
  • Please remain courteous, polite, respectful, and constructive in all communications during this review.
  • Point out possible flaws in the person's work and take the time to discuss and debate them.
  • Keep in mind that sometimes there may be differences in interpretation of tasks and scope of functionality. Please remain open to each other's vision.
Guidelines
  • Evaluate only the files located in the src folder of the student's or group's GIT repository.
  • If you have not finished the project yet, it is compulsory to read the entire instruction before starting the review.
  • Ensure to start reviewing a group project only when the team is present in full.
  • Use special flags in the checklist to report, for example, "empty work" if the repository does not contain the student's (or group's) work in the src folder of the develop branch, or "cheat" in the case of cheating, or if the student (or group) is unable to explain their work at any time during the review, or if any of the items below are not met. However, except in cases of cheating, you are encouraged to continue reviewing the project to identify the problems that caused the situation so that they can be avoided in the next review.
  • Double check that the GIT repository is the one corresponding to the student or group.
  • Carefully check that nothing malicious has been used to fool you.
  • In controversial cases, remember that the checklist determines only the general order of the check. The final decision on project evaluation remains with the reviewer.
  • Check whether the feedback form is filled or not (https://new.oprosso.net/p/4cb31ec3f47a4596bc758ea1861fb624).
