Modify the controllers so that Xcontroller.method is a method that assumes res.locals.X has been assigned.

Allow owner to add TAs by email address
and create a TA collection which associated TA emails with classId's and userIds

When someone enrolls in a class, the system will check to see if they are a TA and if so
it will add a TA flag for that course in their user profile.

Students can look at the reviews of their answer and
their reviews of other's answers

Instructor sees summary data for all students
name, email, #answers, avgscore, then numReviews/AvgReview for all answers

Find a way for the instructor to mark a student as a drop or audit
and don't include them in the grade summaries..

I need a page that shows all students with their status

• enrolled
• dropped
• guest
• TA
  and add this field to the user model

Highlight the instructor reviews

Find out why and also write a route to remove the duplicates and update all of the cached fields
(e.g. the "reviewedBy" list)

Modify the user collection to include a list of all of the problems completed. We can then use this to highlight the questions which have already been answered. We could also include a list of the reviews for each problem completed by that user. This would allow us to give them instant updates about their status of their answers and reviews for each problem in a problemset.

Show the number of answers to a question, the number of reviews, and the average review

Allow the owner of a class to edit their classinfo, problemsets, and problems

Instructor or TA can see all work for one student
problems answered
answers reviewed
reviews of their answer

Let the user know how the system is rating them on each page
e.g. on the problem page show their average review and the number of problems they have reviewed

The use of .save is problematic and leads to race conditions that actually come up regularly during class. So I need to refactor to use .update
and $pull (but I don't know if $pull will pull out compound objects...)

Allow students to get a quick look at their status in all of their courses.
It would show the (number of )

• answers submitted
• reviews of those answers and the average score
• TA reviews of those answers and their average score
• reviews submitted and their comparison to average score of all students and TAs

This would allow students to gauge their progress in their courses....

Allow users to downvote as well as upvote.
This will allow us to see which students have the best record for writing popular reviews.

Add visibility checkbox to each problem (and allow problem edits)
Show a student all of the other reviews after they submit their review

Create a page where the owner can see all student in the class with their status
and can update their status (except the owner status).

Find a way to report on the accuracy of each students reviews (e.g. comparing with TA reviews)

Replace all occurrences of "class" with "course" because class is a reserved word in Javascript

write an installation manual and release videos about how to use it for Brandeis faculty.

add indexing to mongo database
remove console.logs/dirs

Change the model so that once a students has written N reviews for a problem (say N=5)
they can see all of the answers and reviews for that problem.

This will motivate students to write reviews...

Implement the TA/instructor view of a problem set
where we see just the TA grades for each student and each problem
Allow the TAs to click on a (usually ungraded) problem to grade it
Highlight the TAs grade to the students so they can see an official grade
If more than one TA grades the problem set then average their scores for that problem.

I get an exception from a race condition on updating the pendingReviews field of the problem objects.

Some solutions are to use problem.set or $pull or problem.update,
but a better approach might be to create a new table pendingReviews
to keep track of the pending reviews...

or use a try clause in a loop?

The best approach is probably to use $pull ..

Modify PRA so that it uses connect-mongo to store the authentication session data
and the use PM2 to invoke the cluster code to startup multiple servers on different cores!

When owner tries to make a review ...

Find out why answers and reviews are being duplicated and fix this bug!

Allow the user to see their reviews and to edit any of their reviews.
Allow the instructor (and/or TAs) to delete and/or modify any student's review.

Allow students (including TAs) to edit their reviews
Allow TAs to delete anyone's review... (e.g. if it is offensive!)

Modify the problem set view so that it shows the number of answers and reviews for each problem

Instructor can see all answers and then click on a link to see all reviews of that answer

Generate a CSV version of the gradesheet

Create a page which shows the progress on each of the problems in a problem set

• how many completed each problem
• how many reviews are there for each problem

let the users respond to a review with a rating from -2 to 2
along with a comment about the review...
We could put the response into the review itself since each review is unique to an answer and a reviewer...

Eventually, I will ask the reviewers to pick the best review after they have made their review
and we will keep track of the number of votes for each review. We will also need to filter the
reviews so that only a few well-chosen reviews are shown, e.g.
the past five reviews, and then the most selected reviews after that weighted by longevity ...

So we'll also need a couple of variables keeping track of the number of votes and the "time" of the last vote...

Let students see how others judge their reviewing....
e.g. (total up - total down)/(totalup + totaldown) which is their average review (between -1 and 1)

Modify the code so that the student names are not shown to the instructor during review others activity.

Allow students to see only the answers that the instructor (and/or TAs) indicated were perfect!

The owner should be able to see how many answers and reviews there are for each problem in a problem set.

A student should be able to see which problems they have answered and how many reviews they've made.

Allow instructor to see all of the answers to a problem

Allow the owner to add TAs to a class by specifying their email addresses.
Allow TAs to have access to some of the owner-features
Mark reviews by TAs so students can see the official reviews
Grade ProblemSets as Quizzes using only the TA grading..

Allow the instructor to close the question and disallow any additional answers.

The easiest approach is to just not allow them to post an answer....
But this would also keep them from viewing the other students answers and reviews.
That might be OK as it will create further incentive to post an answer....

I think I'll go for this easier solution. I can just add a field to the question which indicates whether
students are allowed to submit answers. It starts as true but the instructor can set it to false (or back to true).
