Online Lab Submission
Once the assignment due date has passed, it's time to grade the essay/image answers that were submitted by the students (see Submitting Essays / Uploading Images to review the student part of the process). Graders access the grading webpage by clicking a descriptive link for the essay/image (i.e. Procedure, Image (Excel Graph), etc.). This web-based approach saves time and improves grading accuracy with the following features:
- Typed Answers - avoid the frustration of trying to interpret illegible handwriting . . . . typed responses make grading easier and the text can be formatted using a robust HTML editor.
- Save Time - no more flipping through a stack of lab reports to grade a one question at a time for the entire class, simply scroll down to the next student's answer.
- Essay Graded - once you have graded an essay question, the descriptive link will have "(Essay Graded)" at the end as a completion notification.
- ToDo List - the TA's and Instructor's "ToDo List" is automatically populated with links to essay questions that need to be graded. Once graded, the essay is moved to the "Completed Work" list.
- Pertinent Information - any information saved in the Chem21Labs database can be provided on this grading page to help the grader. For example, if the question being answered is "Based on your experimental data, . . . . . . . ", the Chem21Labs program can list this relevant experimental data along with the student's essay answer to give the grader everything they need to accurately grade the essay answer.
Deduct Points Buttons - when the grading page initially loads, the Points to Award box contains the maximum number of points. To the right are three buttons that allow the grader to swiftly deduct points when necessary.
- Saved Work - electrical or internet outages will not result in lost work. The grader's work is saved after deducting points or entering comments . . . . confirmation is displayed on the webpage as "✔ Saved" to the right of the last button (see image).
Automated Comments - anyone who has graded essays knows that much of the time is spent writing (and re-writing) the same 4 - 5 comments for similar incorrect answers. To save some of this time without sacrificing quality, the right side of the grading webpage contains a floating Comment Box that contains the most common comments typically given for the essay question being graded. Below the Points Awarded section are 10 buttons that are "linked" to the 10 Comment Boxes - clicking Button #3 will place Comment #3 in comment box for a student. Multiple buttons can be clicked to add several linked comments to a student's essay answer to help them understand an incorrect (or missing) part of their answer. The comments entered on this grading page automatically show up on the students lab report webpage directly below their essay answer.

- Manual Comments - for those times when you want to change the automated comments or add a comment not listed in the side panel, you can click in the comment text area and manually enter your remarks.
- Grading Images - uploaded images are graded using the essay grading webpage. When the descriptive image link is clicked, the grading page displays the student's uploaded images as the "answer."
- Ordering Links - student answers can be "ordered" by the following:
- Name - default
- Answer - students that entered the same answer or very similar answers will be grouped together.
- Points and Comments - the grader can fine-tune their assessments when students with similar points are grouped together.
- Per-Student Grading Text - if students entered a Yes/No answer and then an explanation, you can pull in the Yes/No answer as described in #3 (Pertinent Information) and click this link so that all the Yes explanations appear together and all the No explanations appear together.
- TA - when an instructor's lab class hase 100 students with 4 TAs (25 students each), this link will let the instructor know which TA has not graded the essay answers.
- Students with an answer but 0 points - the grader can double-check this subset of students to see if any partial credit is warranted.
- Grade Another Class Link - graders with more than one lab class can quickly "jump" to another class to grade this particular question.
