Question

다음 매니페스트를 참조하십시오. 처음으로 다음과 같은 콘텐츠 패키지를 시작한다고 가정 해 보겠습니다. 학습 관리 시스템 (LMS)에서 시작 버튼을 클릭 할 때 어떤 활동이 제공되어야합니까?

Answer 1

액티비티 4가 먼저 전달됩니다. 설명 : 1. preConditionRule objectiveStatusKnown 때문에 활동 1을 건너 뜁니다. 2. 활동 2는 상위입니다. 3. 활동 3은 상위입니다. 4. 활동 4는 첫 번째 사용 가능한 리프이고 상위 (활동 3)의 "흐름"이 참으로 설정되어 있습니다. 매니페스트의 작동 방식을 이해하려면 http://www.naseelco.com에서 Visual Manifest 2004를 다운로드하십시오. 매니페스트를 시각적으로 표시합니다. 매니페스트를 테스트하려면 동일한 웹 사이트에서 LMS2004를 다운로드 할 수 있습니다. 그것은 완전한 기능을 갖춘 LMS이지만 서버가없는 로컬 컴퓨터에서도 작동합니다. 아래는 Visaul Manifest 및 LMS2004에로드 된 매니페스트의 스냅 샷입니다.
