Forked sandbox is not saved for current material in the editor. The sandbox will be forked, but the current material will be using the old one.

Right now there is only xhat and yhat for the vector free-response problem type, and we want to add the numbers 1, 2, 3, 4, and a + and - button.
We got feedback that it's not very user friendly because the user has to go back and forth between their keyboard and the graphical xhat yhat buttons.

If you click on a multiple choice button answer that contains MathJax, you have to click on the edge where there isn't any MathJax, otherwise it just highlights the MathJax and doesn't trigger a button click.
Example here: http://www.physicsisbeautiful.com/curriculum/lessons/KvVb5FRY6tYoyGNsa6hyUW

Remove the https://www.googleapis.com/auth/plus.me scope from your codebase as well as project. This scope is a Google+ scope that is no longer functional.

Now users can create curricula, so we will get many values in ShortUUIDField fields. But the value of this field can be not unique

First step: In all ShortUUIDField in curricula models, we must set unique=True.
Second step: to exclude DATABASE "UNIQUE constraint failed" we need to create a field validation process before model object save.

The scoreboard is based on the UserReaction model now.

So we got two issues:

1. The scoreboard works based on material. E.g. if we will create two materials with the game based on the same Material problem type, we will get separate scoreboard lists for each material (independent from Material problem type). I think it is normal behavior.
2. The Scoreboard may contain the current user more than once in the list. Suggestion: use last_reaction flag to filter responses from unique user (not implemented yet).

Current list of content we need to build:

• Basic math
• Unit conversion
• Graphs
• Triangles

Relevant comments from Reddit:
mouettefluo: Usually, platforms like that are based too much on calculus. Something to be made outside of the app, on a classic calculator and then you enter the answer in the little box. Doing that is actually less convenient and slower than solving the problem entirely on paper. It's an error often seen, using the app as a substitution with no added value instead of making the best with what the technology has to offer.
What I liked about your app is how it's quick and effective. It's based on concept and not much on calculus. In other word, much more on comprehension than application.
For the vectors, I liked how there was no given origin and there was some freedom given to the student. That's also something important to favorise motivation in learning (it's a proven thing, but my references are books in french, so no link)(can also be found in gameplay theory)
That being said, what content would I want to find on your platform?

• Units. Yes, the boring conversion, but mostly identification of the actual quantity itself. Student have a hard time differentiate Force/Energy or Speed/Acceleration. Concept wise and unit wise, Force/Energy/Work in particular.

• Math. Please basic maths. Fraction with variables(simplification of). Finding x with a simple isolation (2-x=7) or (2x/3 -7=4) or (x/4-2=x/5). Distribution, two equation two variables, etc.

• Graph: what is the particule doing here ? Going back ? Positive or negative speed? Acceleration ?
  For a given situation, in which direction would you draw whatever vector.

• Triangles. Deducing the value of an angle. Decomposition of vectors. Finding the x component of __.

• More difficult but eh, I can dream : from a text, extrapolating the correct equation.

My students have been drilled with this in highschool. They didn't saw the actual importance of it so it was not in their priority to memorize it correctly. They just need a little quick refresher. A quick refresher I can't offer myself because I don't have time to grade the catch up homework I would give them. One or two students by semester ok, but not 25 of them (my classes are around 90 heads). To them, catch up work is boring and takes time over the new stuff.
My personal criteria to recommend an app/website to a student - Not something too childish (like making a character and win points to buy virtual clothes/gear) - It has to go to the point (minimalism in the theory presented) - Nothing more boring or less efficient than doing it on paper - Has to enable the user to be autonomous in his progress
For sure, I'll propose your app to struggling student this fall and would return any feedback if I hear some.
Also, I really agree with the others suggesting that you should add a note regarding the xyz vectors and the unit vectors ijk.
I teach college students (17-20 years old). One third of my students struggle a lot with notation and graph interpretation, but also with basic maths (fractions, finding x, trigonometry). Since they are behind, they have to catch up by themselves outside of the school. I want to give them material to help. That's something I need and never found anything interesting. Often is too much geared toward children and, at their age, they would feel ashamed to browse and train on such websites/app.
I think the simplicity and type of gameplay you have would be very popular for the highschool level and but also my slower students in college. I really hope you plan on including a basic math game :)

This is a bit of a corner-case, but if a user has finished all lessons in a module, then we add a new lesson, it should be accessible to the user. Currently it requires repeating the lesson before it to "trigger" the unlocking.

Also, for testing or demonstration purposes the admin should have the ability to have all of the lessons unlocked.

We want the ability to send notification messages to users

To simplify UserReaction.reaction_start_on and reacted_on are getting from frontend. Is not secure because the user can send any values.

Suggesting solution: user request material -> create UserReaction with reaction_start_on (datetime.now()) and hash (uuid) fields on the server side -> send requested material with user_reaction_hash field -> after an answer user send response with user_reaction_hash field -> backend update reacted_on with user_reaction_hash (uuid) and save reacted_on datetime on the server side.

Priority: low.

move api urls from https://github.com/nscozzaro/physics-is-beautiful/blob/master/editor/urls.py to urls_api.py
(see also https://github.com/nscozzaro/physics-is-beautiful/blob/master/pib/urls_api.py )

ps. stay to using drf routers

We need to add browser tabs sync in the Editor (and on other parts of the site probably).
The reason: e.g, we have a list of Materials in the editor in 2 tabs. When we remove a Material in the 1st tab - the Material will still exist in the 2nd tab (until we fully will reload the 2nd tab).

Suggestion: https://www.jameslmilner.com/post/tab-state-service-workers/ (we already use Service workers in code sandbox editor).

Priority: low.

Django error views page_not_found, server_error, permission_denied and bad_request. By default, they use these templates if they can find them, respectively: 404.html, 500.html, 403.html, and 400.html. We need to add these templates to /templates/ root dir.

We need to clean old data with the expired date from django_session table. Django session may contain session_data field with too much size value (~2Gb per year for current count visitors).

If you check the "null" checkbox, it should clear upon answering the question. Currently it's remaining checked even after you answer a question.

Also, if you draw a null vector on the grid, it should automatically check the checkbox.

For example, this page.

We need to create vendors.js chunk to reduce sizes of js bundles. Now, each bundle contain react+react-redux+react-bootstrap.
So we need to cut these packages from each bundle and place it to single vendors.js.

However, it was working when the old djeddit fork was in use. Look to that for any potential bug fixes.

Rewrite clone (PostgreSQL) functions for structure units.

When you complete the sign-up form, an email should be sent to verify the account

We want to add a game where the task is to convert something like 0.001 cm, or 2 weeks, or 1 foot 4 inches to SI units. To do this, we'll have a grid with drop-down boxes or math-entry boxes. Details to be decided.

We need to minifying All JavaScript and CSS bundles in production mode.

Add 'new course creation' tutorial.

1. the extra closing span tag

2. /templates/blog/navbar.html, /templates/navbar.html and templates/allauth/account/base.html almost identical. We have to use a DRY principle.

3. [DOM] Found 2 elements with non-unique id #id_remember: (More info: https://goo.gl/9p2vKq) <input type=​"checkbox" class=​"form-check" name=​"remember" id=​"id_remember">

4. https://github.com/nscozzaro/physics-is-beautiful/blob/master/blog/templates/blog/wordpairs.html#L4

Block name must use the function naming rules: lowercase with words separated by underscores as necessary to improve readability.

5. https://github.com/nscozzaro/physics-is-beautiful/blob/master/blog/templates/blog/wordpairs.html#L7 css needs to move to /static/blog/style.css

6. https://github.com/nscozzaro/physics-is-beautiful/blob/master/blog/views.py
   all def (functions) also must use the function naming rules: lowercase with words separated by underscores. See pep8 for details.

7. I think we must avoid using id="navTopOfScreen" camel case in ids also. We need to convert all values of tags attributes to a uniform style. I suggest using BEM methodology http://getbem.com/introduction/ , but we can use own style (e.g. lowercase with words separated by hyphens or underscores).

Eliminating the requirement of a username can hopefully resolve the issue that social login redirects to a page asking for a username. We want social login to take the user directly to the curriculum page.

Replace native bootstrap with https://react-bootstrap.github.io/components/progress/#progress-bar-props

This is a long-term goal.
Teachers want to assign certain practice to their students. Different teachers may teach the material in a different order, or may want to add/tweak/customize lessons. We need to have tools so that teachers can create a custom curriculum from the content that we have, and assign it to students.

Thanks! The use case I can see is having students work through a part of this tutorial, but if I can't jump directly to the part I want students to work on, there's no way I would assign it. Also, if I want to look at the Newton's laws part, for example, it's annoying to have to go through all the preliminaries just to see if I like the material.

1. SPA loads material from API by UUID that contained in browser URL to determine material problem type UUID
2. Material problem type UUID is sending to code sandbox eval app (into iframe)
3. Codesanbox component loads material again to use JSON DATA / Codesanbox game do not use JSON DATA right now (but it can in the future I think).

So we have an issue here:

• twice loading the material from API (from the same URL)

And question:

• Is the game will have JSON data as in the component?

update.

After we check the user's answer - we will get the Next material UUID (with User Reaction response) - then we send this material UUID to the parent browser window from iframe (a sandbox code). Then we change a URL (set UUID) in the web browser window and send this UUID to the current Sandbox component. Current (prev for next material) component loads Material from API. The current component has its own Material problem type UUID. So If this "Material problem type UUID" != "Material problem type UUID from next material UUID" - current component will be reloaded (iframe with new component), otherwise, only JSON data will be reloaded inside the component.

I think, for clarity, we need some graphics for this process.

If we will have e.g. 'Common' topic name then this function will be raised Not Found error.

I think we should use slugify function before we will start to get a Topic object.

After someone completes or fails a game, it should show a high score list

4. Reselect None - start from scratch
5. Click "Create curriculum"

replace deprecated react-router-redux with connected-react-router

When you click an incorrect multiple-choice text button, all buttons go disabled but they don't change color (clicked wrong answer should turn red, correct answer should turn green). It looks like the code is similar to the image multiple choice which is working, so I'm not sure why the multiple choice text code isn't working

When a user just clicks and releases on the grid, it automatically checks the null vector checkbox. This has been reported to be hard to notice for some users, so an animation that draws attention to the fact that it's getting checked could solve this issue.
