This program was conducted to analyze the effect of a robotic program in assessing technological problem solving among primary school children. The content in the learning module which contain technological problem solving and visible thinking activities has been going through expert validation before it were applied in this study. The instrument used to measure the technological problem solving is Technological Problem Solving Inventory (PSI-TECH). Quasi-experiments was implemented in this study, involving experimental and control group which were equal and homogeneous in selected characteristics. The robotic and basic visual coding program was conducted for 5 months, with an hour of lesson each week, consistent with the school syllabus and activities. Result obtained by collecting the data before and after the program, and quantitative analysis of t-test and MANOVA were used. Result had shown a significance positive value for the experimental group after the program. This study contributes in the field of education, in investigating the technological problem-solving skills among students. In addition, help to diversify the studies in the field of robotics.
