The objective of this research was to develop a lesson plan, to study achievement, and to study creative thinking on two-dimensional geometric figures and geometric transformation by using productivity-based Learning and GSP. The research sample was 30 seventh grade students for gifted child in the science and mathematics curriculum from Valaya Alongkorn Rajabhat University under the Royal Patronage Demonstration School in the first semester of the 2017 academic year. The design of this study was the one group pretest-posttest design. Tools used in this research were a lesson plan, an achievement test, and a creative thinking test. The achievement test had Reliability of 0.79, Item Difficulty of 0.38-0.54 and Discrimination Power of 0.52-0.76. Time taken for this experiment was 20 hours. From evaluating the knowledge of students on two-dimensional geometric figures and geometric transformation, students had an average score from the total score 100 in pretest and in the achievement test equal to 47.90, and 83.13, respectively. After the study, the students had better achievement, at the level of significance .05. The students had average learning development at 67.61%, and lesson plan on two-dimensional geometric figures and geometric transformation by using productivity-based learning and GSP had efficiency at 91.04/83.13%. After the study, the students had creative thinking at the level of significance .01 (p<.05).
