Developer

Confidential

Responsibilities:

• BP4ED is a cloud-based web system designed to facilitate teh role and interaction for SMEs, instructional design (ID) experts, technical design (TD) experts, and production personnel (PP) t providing them with online best practices on ID and TD.
• BP4ED embodies some of teh best practices suggested by Horton to organize eLearning content and by Clark and Mayer, to present (display) such content.
• BP4ED consists of a set of templates designed to correspond to teh units of eLearning. When eLearning content is designed with BP4ED, selecting teh desired units of eLearning entails to automatically assemble teh corresponding templates into teh corresponding hierarchy — SMEs will tan write or insert relevant content (text or multimedia resources) in teh fields of teh templates selected.
• From teh resulting structure of a course thus designed, BP4ED determines both navigation and interactivity by teh user, thus eliminating teh corresponding design and implementation work.
• BP4ED was implemented with Apache server, MySQL, PHP, JavaScript, CSS3 and HTML5.
