Have you ever googled it? There are endless explainers that throw diagrams and terminology at you, generally leaving most people more confused. Schemas? XML? XSDs? What even are these things? You don't even need to know.
CourseAssembler will create packages that are SCORM compatible. This means any LMS that supports SCORM revision 1.2 or revision 2004 (terrible version numbering!) will accept pages you create with Course Assembler. Furthermore, you can specify how learners get their completion all without knowing "what SCORM is".
If your LMS says it supports
SCORM 2004 then pick that option when you export your package. If you just want the files and will not be hosting the package on a LMS (perhaps you'll be embedding it on your Wordpress site), you can pick the Standalone option.
At this time, we do not support xAPI, but have it on the roadmap.
You sometimes still hear the term HTML5 being bandied about. Is HTML5 the same as SCORM? What even is HTML5 and is it any different to HTML? Well, yes there are differences, but nothing you need to know. HTML5 just means "web pages". Formats like PowerPoint and OpenOffice don't just work inside web browsers - you need to have software to open and recognise those formats. But HTML5 is the language of browsers, so CourseAssembler converts all your document and slide formats to HTML5 so it "just works" in browsers.
If you have searched for SCORM recently you will have probably heard the term xAPI or "Tin Can". These are "replacements" to SCORM - except they aren't really. They are ways of recording that learners "did stuff". SCORM defined that "stuff" was learning content and it gave you a score and a completion. xAPI is more vague. It's not even explicitly for learning at all, even though that's where it is mostly used. xAPI doesn't have as much support in LMS's as SCORM.
xAPI "Does Stuff" ? It can record a user clicking a link. Or scrolling the page. Or ticking three boxes, hopping around on one leg, and spinning their ipad around seven times anti-clockwise. If the programmer handles it. None of this might represent a learning outcome. xAPI records information about actions the users can do, but doesn't necessarily inform any service about scores or completions. It evolvede from SCORM's standards and internal workings, but it is not really the same thing.
