Curriculum-ideas Analytics (CiA) is an analytics tool designed to support teachers and students in understanding the “big ideas” in their discussion in light of an extended curriculum that is mapped across grades (from Primary to Junior colleges) and subjects (e.g. science, and geography). We illustrate the design for the theme of electricity, but other focal themes developed in CiA included heat (Science and Geography), cells and war (History). In the CiA for electricity, the researchers mapped the specific instructional objectives (SIOs) from topics in our national curriculum documents for different grade levels to a few focal theme, e.g. Electric system. The purpose of the mapping is to capture the growth of curriculum knowledge related to focal theme from inter-topics and/or inter-disciplinary (where possible) across grade levels from year 1 to 12.
