Abstract This articel explain the result of how to expand thinking indigenously ability as an element of thinking creatively in math learning to junior high school through Generative Learning with Open-Ended Approach (PGPOE). The experiment used quasi experiment with SMP Negeri 17 Pamulang as the subject and formed experimental class and control class. It can be analyzed quantitatively using t-test. The result showed there were significant differences (p-value less than 5%) between the student who were taught with PGPOE and the student who were taught with common learning at thinking indigenously ability. It showed that the student’s thinking indigenously ability who were taught with PGPOE is much better than the student who were taught with common learning. Keywords: Generatif Learning, Open-Ended Approach, Thinking Indigenously. Abstrak.

This research explores the impact of Guided Inquiry Learning-oriented learning with a scientific approach on understanding mathematical concepts of PGMI UIN Fatmawati Sukarno Bengkulu students. The research design uses an experimental method with an experimental group and a control group. The results of the analysis show that students who were taught using Guided Inquiry Learning-oriented learning experienced a significant increase in understanding mathematical concepts compared to learning without a Guided Inquiry Learning orientation, even though both used a scientific approach. A significant value of less than 0.05 in a statistical test indicates that the difference can be considered statistically significant. However, the results of further analysis showed that there was no significant difference in increasing understanding of mathematical concepts between classes that used the Scientific Approach and the control group in two particular classes (Class=2 and Class=3). A P-value greater than 0.05 in statistical analysis indicates that the results are not statistically significant. Thus, although there was a significant increase in understanding of mathematical concepts in the group that implemented Guided Inquiry Learning-oriented learning, this research also showed that there was no significant difference in this increase between this group and the control group in two particular classes. These results provide further understanding about the effectiveness of certain learning methods in improving students' understanding of mathematical concepts.
