Background and Objectives: The purpose of this study is to investigate the use of researcher-made examples by GeoGebra software as an educational tool to increase the learning skills of geometric theorems and assess the attitude of 11th-grade math students towards geometry and provide a practical model for teaching geometry.Methods: This research is a quasi-experimental type with an experimental group and a control group. It uses pre-test and post-test and is applied in terms of purpose. The statistical population of the present study included all-female high school students in the eleventh grade of mathematics in the districts three and four of Isfahan in the academic year 2021-2022. The statistical sample consisting of 120 students was purposefully selected using the available sample method. A pre-test of geometry course 1 as well as a three-scale Cattell intelligence test were administered to all groups in the same manner. A researcher-created questionnaire on a five-point Likert scale was given to all groups to assess the students' attitudes towards geometry before and after the research. The opinions of experienced education consultants and teachers were used to assess the validity of the questionnaire, and after correction, it was made available to students. The Cronbach's alpha coefficient was used to determine the reliability of the questions. Reliability was 0.93 indicating the high reliability of the questionnaire. The experimental group was taught how to use, construct simple shapes, and measure the components of shapes in GeoGebra via cyberspace, and their problems were solved by the researcher in five one-hour sessions.A researcher- created nine practical examples related to the sections of the circle and transformation sections in Geometry 2 using the opinions of five experienced professors and teachers, their answers were designed using GeoGebra software, and they were provided to the experimental group. Using this software, they guessed the components and checked their accuracy. The correct answers were then given to them. They also deduced the original form of the relevant theorems and demonstrated them. During this time, the control groups were given the contents of this section of the book in the traditional manner. The post-test was administered equally for all groups at the end of this period. The inferential part of SPSS 25 software, which included MANCOVA analysis, Kolmogorov-Smirnov test, Levin test, and M box test, was used to analyze the obtained data.Findings: The results of MANCOVA analysis show that the use of examples made by GeoGebra software compared to traditional teaching has a statistically significant effect on students' ability to guess and learn geometric theorems. In addition, the questionnaire given to the students show that they value the use of GeoGebra to solve these examples and guess and prove the theorems related to them and have more motivation to participate in the geometry class. Conclusion: According to the findings, the teaching method of proving a geometric theorem by using examples made by GeoGebra software increases the amount of learning in the classroom and increases students' motivation to learn geometry, and makes the classroom more attractive to them. This method increases students' creativity and causes them to be more involved in the learning process and becomes more active in the classroom, and these skills enable students and facilitate learning in the geometry classroom. There were some issues with the research. Some school principals, for example, refused to allow this method of teaching geometry. Some geometry teachers were also unfamiliar with GeoGebra software. In-service courses in this area are ideal for math teachers who want to help their students learn geometry more effectively and enthusiastically.

Background and Objectives: Educating creative people is one of the important goals of educational systems. Undoubtedly, using educational models appropriate to educational content provides a suitable platform for achieving this goal. Innovative and 5 E patterns lead to increasing student creativity. In the innovation model, the student tries to look at the problem with a new perspective and turn it into a familiar problem by analogy and simile. In the 5E inclusive model, the student discovers relationships, solutions, and concepts through participation in a variety of activities. The aim of the present study was to investigate the effect of educational interventions based on innovation and 5E patterns on the academic performance of 9th grade students’ geometry. Methods: The research method was quasi-experimental in which pre-test, post-test design with control group was used. From the statistical population of 9th grade female students of Tehran public high schools, 3 classes, each class included 30 students as a sample, were selected by convenience sampling method. Then two classes were randomly selected as experimental groups of innovation and 5E and one class as control group. Data collection instruments included researcher-made performance tests tailored to innovation models and 5E, while the reliability and validity of these tests were assessed only for group 5E and the results were generalized for innovation groups and 5E. In order to collect the data, at the first phase, performance pre-tests based on the basic geometric concepts were administrated for innovation, 5E and control groups. Then, the content based on innovation and 5E patterns and the traditional method for innovation, 5E and control groups were implemented by the researcher in 8 sessions for 60 minutes in five consecutive weeks. Finally, the researcher-made post-test based on the geometric concepts was run for innovation, 5E and control groups. To analyze the data descriptive statistics (including mean and standard deviation) and inferential statistics containing Kolmogrov Smirnov (to check the normality of the data) and the ANOVA were used by SPSS statistical software. Findings: The results of the research in the descriptive statistics section showed that the mean difference between the pretest tests of the performance tests of the innovation groups with 2.73 and 5E with 3.16 compared to the control group with 0.42 showed significant differences. Also in the inferential statistics section, the results of the ANOVA test for pretests of the innovation, 5E and control groups indicated that the academic level of the students of innovation, 5E and control groups was the same. (0.05 <0.963). The results of the ANOVA test for post-tests of innovation, 5E, and control groups showed that 5E and innovation had a positive effect on the performance of 9th grade students in geometry. (0.00 <0.05). Conclusion: The use of innovation models and 5E led to students’ performance, so the educational system should emphasize the use of the methods that aim to increase interaction and cooperation between students. Therefore, it is suggested that the necessary training should be introduced in the curriculum of teacher training in order to get acquainted with and apply active teaching methods such as Baybi. Also, the content of textbooks should be organized based on active teaching methods, so that these methods can be taught and implemented in teaching materials. This research has been accompanied by limitations that may affect the generalizability of the research findings. Because it is not possible for the researcher to control disturbing variables such as intelligence and gender, these variables have some effect on the results. Also, due to time and space constraints and the issue of necessary permissions, this study was conducted only among 9th grade female students. Naturally, increasing the sample will lead to more accurate results.
