  We have integrated Easy JavaScript Simulation (EJSS) Data Analytics into the
national Learning Management System for Singapore schools, known as the
Singapore Student Learning Space (SLS). EJSS Data Analytics enhances the
teaching and learning experience for educators and students by enabling
educators to monitor and evaluate students interactions with interactive
computer simulations. The data analytics and visualisation capabilities are
delivered using the Moodle platform and version 1.3 of the specifications for
Learning Tools Interoperability (LTI). In this paper, we showcase the potential
for EJSS Data Analytics to identify students learning difficulties and
misconceptions. Four examples of EJSS Data Analytics applications are provided
to illustrate insights on aspects that include understanding a students
sequential actions leading to specific task outcomes, the frequency of task
attempts by each student, and the ratio of students achieving correct versus
incorrect task completions. We identify five key considerations for designing
the EJSS teacher dashboard. These considerations relate to Student Thought
Process, Student Behaviour, Student Engagement, Student Choice, and Teacher
Feedback. These five facets provide a framework for aligning our design efforts
with the needs of students and teachers, also drawing upon research in data
analytics for education.
