scorm | SCORM 1.2/2004 Wrapper for JavaScript/TypeScript

Questions are called 'interactions' in the SCORM run-time data model.

The specific property that says whether a question response is correct or incorrect (or how correct the response is) is cmi.interactions.n.result (where n is the index of the interaction).

You might also want to look at cmi.interactions.n.correct_responses.n.pattern and cmi.interactions.n.student_response.

There might be a couple different issues at play here.

First off, I'm not sure that SCORM Cloud allows for the Unity Player mime type today. That could be verified with a request to support@scorm.com and it may be able to be added if it isn't currently supported.

Second, how are you communicating with the SCORM API? When a SCORM course is launched in the player, there is a javascript API exposed with some basic calls you need to make. This is where you'd set completion or a score (or suspend_data if needed) and it tells the LMS what data to persist for the learner session and makes values available from previous launches if set to resume.

This won't happen automatically, so you need to handle that in your Unity package with either a wrapper, or some javascript calls to the proper context from within the package.

Hopefully all this is helpful for your understanding of SCORM. Feel free to reach out to support@scorm.com since you're using SCORM Cloud and they can help you if you need more information.

Note: I work for Rustici Software on the SCORM Cloud team and have some light Unity experience.

Your question is a bit confusing. SCORM is an API tying two things together:

• learning content, usually in the form of one or more so-called SCOs (i.e. HTML files with assets talking to the SCORM JS API)
• an LMS serving the learning content and providing the SCORM JS API instance

It looks like you are trying to create learning content, although you provide a way to change the learner name, which is read-only data provided by the JS API.

If that's what you're trying to do, it's not up to SCORM to tell you the score but to you. Based on your code I'm guessing you want each question to be worth a number of points (or at least just one) if answered correctly and the score should be based on that and the total number of questions.

Since you're storing all answers in cmi.interactions already, you could try getting the number of interactions (i.e. answers) first. This tells you the total number of answers and thus the maximum number of points, or cmi.core.score.max.

Since the lowest possible score is zero points if you do a simple tally instead of something more complicated like negative points for incorrect choices being selected, the cmi.core.score.min would then be 0.

The cmi.core.score.raw would be the total number of points, so the number of answers that are correct. You could get this by iterating over the values of cmi.interactions.n.result you set previously (with n being the index between zero and cmi.interactions._count and only counting those where the result is "correct").

However note that submitMCQ should set cmi.interactions.n.result to "correct" or "incorrect" not true or false. A conforming LMS will otherwise reject the value as invalid (which does not raise an exception but instead sets an error flag you have to check explicitly because SCORM is weird like that).

Your reading of the pseudocode is correct. Choice is a bit special compared to the other flow events, but the steps of termination and showing the user a "please select an activity from the activity tree" screen could happen in several cases. The only somewhat unique part is the setting of the current activity, which makes it so other flow navigation events the user may select start from their last intentional choice, and not from whatever was previously loaded. It's not unusual for the Current Activity to be on a cluster, as stated on SN-4-18: "During termination behavior, Sequencing Exit Action rules are evaluated on all of the ancestors of the current activity – this is done in the Sequencing Exit Action Rule Subprocess. The result of this subprocess will be that either the “just terminated” leaf activity remains the Current Activity, or an ancestor of the leaf activity becomes the Current Activity".

You're also correct that OP.1 ("Overall Sequencing Process") is mute on the topic, going so far as to say "Behavior not specified." for a Not Valid sequencing request. I believe the most common choice is the aforementioned "please select an activity from the activity tree" style screen in place of where the visible SCO would have been.

The spec tries very hard to separate LMS display choices from how sequencing itself operates. SN-5-3 states: "SCORM imposes no requirements on the type or style of the user interface presented to a learner at run-time, including any user interface devices for navigation. The nature of the user interface and the mechanisms for capturing interactions between the learner and the LMS are intentionally unspecified. Issues such as look and feel, presentation style and placement of user interface devices or controls are outside the scope of SCORM."

But the specification otherwise says some instructive things. Page SN-3-6 states that "As depicted in Figure 3.2.1c, the target of the Choice navigation request (Activity B) has a Sequencing Control Flow defined to be False. In this case, no activity can be identified for delivery (clusters cannot be delivered). Because Activity B has Sequencing Control Choice defined to be True, an LMS shall provide some mechanism for the learner to select (trigger a navigation request for) one of Activity B’s children directly, but not Activity B."

While this doesn't explicitly state that there should be instructive text displayed to the learner in that SCO area or that the choice shouldn't be allowed, it does state that something should be done that should guide the learner into intentionally performing another step to launch something else. Again, this isn't exactly the same use case, but it's probably the closest it gets relative to choice.

No. The only hard technical requirement is a JavaScript environment (or an environment that sufficiently mimics a JavaScript environment) which is why SCORM is very often considered a browser based specification. "Browsers" and therefore JS environments are finding their way into all kinds of places.

My scorm file is in a different domain then the LMS.

This is your problem.

The only link the SCORM package has to your LMS (and therefore to your reporting) is the SCORM API. Modern browsers do not allow CORS (cross-origin resource sharing) by default because it opens you to XSS (cross-site scripting) attacks.

The package may be able to find the API if one exists on the external domain, but it will not be able to communicate with the LMS directly.

The way I worked around this was to add a wrapper .js file on the external domain that hosted the SCORM API and used Window.postMessage to pass calls back to the LMS.

You then use window.open or your iframe to open a page on the external domain which has access to scorm_wrapper.js and its own iframe that hosts your package.

Because the Window.opener method is not reliable and not fully-featured when the current window was opened from a different origin, we will use the domain directly.

Since we control the LMS, we know the domain it is running on and since we just opened the package, we know it should be active. We can postMessage it to ask for a reply.

Django searches for a templates folder within each app for the relevant template to render. Looks like the first it found was index.html from within the symposium app.

The convention of directory structure for templates is to put your templates within another folder with the name of the app in order to avoid this exact situation with templates of the same name.

Move your index.html file from

/elearning/templates/index.html

to

/elearning/templates/elearning/index.html

and then change your home view function to

This might help to solve & analyze your problem locally.

I have created the index:

PUT /resourcelibrary

Here are a couple options:

• Select the "single activity" course format: This prevents the /course/view.php page from appearing. Users still have to click a button to enter the SCORM activity, but takes clicks and page views out of the UX. This option can be selected in the course settings.

• Customize: Create a version of the SCORM activity that launches without requiring the user to click the entry button on the SCORM activity page. This requires replicating what occurs when the the user clicks the entry button on the SCORM page, but is possible.

Hope one of these is helpful - good luck w/ it!
