Two main platforms of  IDEALS have been well-known by our users: Learning Design System (LDS)   and  Interactive Learning and Assessment Platform (iLAP) . The last part of the system is the Design-aware Learning Analytics and Visualization (DLAV) . Through a suite of learning analytics plug-ins, it supports learning design evaluations  and refinement recommendation for teachers. Learning Design Studio (LDS)  is a pedagogically grounded productivity and collaboration platform for professionals in the Learning Design (LD), Learning Analytics (LA), and Education communities (particularly those interested in using LD to support Teacher Inquiry of Student Learning (TISL)).   The platform provides users with easy-to-use  learning design patterns for various subjects, supplemented by guidance on setting learning outcomes, curriculum components and visual analysis on learning design.             Interactive Learning and Assessment Platform (iLAP) serves as a versatile learning management system that can be accessed by both teachers and students. The LDS and the iLAP are interconnected, enabling the selected tools in the LDS to be conveniently transferred into usable tools on the iLAP, which then collect student learning data for learning analysis.
