Teaching aids in the world of education is a medium that mediates to help clarifying concepts in learning mathematics. This study aims to determine the efect of the use of toy car props on students’ interest in learning mathematics, especially in comparison material. This research was conducted at SMPN I Bola VII class semester 2 of the 2019/2020 scholl year. This type of research is quantitative by using a quasi-experimental methods. The population of this study were 192 studentsof class VII SMPN I Bola with a sample 0f 23 students in the experimental class and 23 from the control class. The sampling technique used is class random technique. The instrument used in this study was a questionnaire of interest in learning. Before carrying out a hypothesis test it is necessary to do a prerequisite test that is a test for normality and homogeneit. The normality test  obtained significant values in the experimental class and control were 0,136 and 0,620, because the value obtained has a significance level 0f >0,05, it can be stated that the data is normally distributed. For the homogeneity test, the results obtained a significant value of 0,001 at a sisnificant level of 0,05, so it can be said that the data is homogeneous. After the data is normally distributed and homogeneous, it is continued with hypothesis testing. Hypothesis testing used the independent sample t-test obtained value of  t-count > t-table where t-count = 6,49 while t-table = 2,01 which means that the use of toy props has an effect on the interest in learning mathematics in class VII SMPN I Bola where students’interest in learning mathematics increases. Thus the teacher can use toy props related to the material and can be used in matematics learning so that students’ interest in learning mathematics increases.

This study aims to determine the quality of the Instrument of Mathematics Learning Outcomes Class V Primary Schools used by educators seen from the level of validity, level of reliability, level of truth, and the level of power distinguishing questions. This research was conducted at SDN Moro in the even semester of the academic year 2021/2022. The population of this study was all 96 students. The sampling technique in this study is to use purposive sampling technique. The sample in this study was 21 SDN Moro SDN students. This study uses quantitative methods. Data collection techniques in this study are tests. Data Analysis Researchers use quantitative descriptive analysis with a percentage. Based on the results of the analysis of the level of validity, reliability, difficulty level, and distinguishing power it can be seen that the quality of the test instrument as a whole is good questions and stored in question banks, namely 5 questions or 17%, revised and used 11 questions or 37% and discarded 14 questions or 46%.

Model discovery learning adalah model pembelajaran yang interaktif dan menekankan pada pengalaman langsung.Tujuan  penelitian ini adalah mengetahui apakah ada pengaruh model pembelajaran discovery learning dan kemampuan berpikir kreatif terhadap hasil belajar matematika peserta didik.penelitian yang digunakan  ialah penelitian  kuantitatif dengan metode eksperimen semu. Penelitian ini dilaksanakan di SMPNegeri I Kewapante dengan sampel penelitian yang berjumlah 52 peserta didik yang di dapatkan melalui teknik multistage random sampling.Instrumendari penelitian ini yaitutes hasil belajar.penelitian ini  menggunakan teknik pengumpulan data dengan  metode tes hasil belajar. sebelum melakukan uji hipotesis  perlu dilakukan uji prasyarat yaitu uji normalitasmenggunakan aplikasi spss 22 uji shapiro-wilk dan uji homogenitasmenggunakan aplikasi spss 22 uji levene statistic. Sesudah  data berdistribusi normal dan homogen di lanjutkan dengan uji hipotesismenggunakan aplikasi spss 22 uji  independent sample t test. Setelah melakukan uji hipotesis di peroleh  thitung = 6,98 lebih besar dari  t table = 2,01. Berdasarkan hasil uji hipotesis dapat di katakana bhawa terdapat pengaruh model pembelajaran discovery learning dan kemampuan berpikir kreatif terhadap hasil belajar matematika kelas VII SMP Negeri 1 Kewapante.

Problem solving abilities  is purpose to knows the injhuenca of using andro visual in cognitve increasing of student. This research implemented in SMA Negeri 1 Talibura on semester two mi periodof 2019/2020. The populasion of this research is all the student of SMA Negeri I Talibura where the sample of the research is the student of ten class mia which 51 student with is class of mia 1 and class mia II. The interpretation of the sample is using tehnigve. This research as aform , of transparant eksperiment type with the design. The tehinige of data collection sheert and test. This research using analysis data technigne,thent is normality test homogenenity test and t-test. Normality test data refers to the data tosttribube with normaly and homogenity that is the data is homogen. Based on hypothesis testing using the t-test shows that the value of tcount = 3.14, while ttable = 2.00. This shows that the value of tcount > ttable so that. it can be concluded that the audio visual media inflecaned to abblity of congnitive of the student of SMA Negeri I Talibura.
