Abstract
This paper introduces CT-Blocks Analyser which is used for analysing computational thinking concepts of CT-Blocks project activities. This uses the emerging techniques of educational data mining and learning analytics to automate the instructional approach for CT-Blocks projects. CT-Blocks aims to infuse computational thinking within K-12 curriculum. The big data toolkit called, CT-Blocks Analyser which is specifically developed for CT-Blocks, a visually appealing programming environment for beginners; a block based programmable platform interconnected with more features in which students enjoy the learning process and it tries to make the users master in computational thinking.
