Muallimin Aek Raso for the 2019/2020 academic year. The population in this study were all students of class VIII MTs Muallimin Aek Raso which consisted of 2 classes, namely class VIII1 and VIII 2. The sample in this research was using cluster random sampling, taken 2 classes, namely class VIII1 with a total of 20 students using a strategy. Expository learning and for class VIII2 consisted of 20 students using inquiry learning strategies. The instrument in this study consisted of a description test of 10 questions which were first tried out in another class whose aim was to see the quality of the test in the form of validity, reliability and difficulty level of the questions. From the data analysis, an average count of 84.15 was obtained with a standard deviation of 7.7 in class VIII1 while the average count was 75.45 with a standard deviation of 6.5 in class VIII2. From the Hypothesis Test Using the Anova Test at Level 5 % obtained tcount ¬ 1.75 and t table ¬ 0.444 Ho is rejected and Ha dite rima. Thus, the conclusion is that there are differences in students' mathematical communication skills using Expository and Inquiry Learning Strategies in the Pythagorean theorem in MTs.

<![CDATA[This study aims to analyze conceptual understanding and increase student interest in learning by using assignment techniques in the form of material and SPLDV questions and also an assessment questionnaire. This research uses descriptive qualitative research methods. The subjects who were the research targets were class VIII in MASS PP IRSYADUL ISLAMAH totaling 35 students. The research instrument used was an assignment questionnaire and an interest in learning outcomes. The material is used to provide understanding of the assignment and see the students' interest in learning the assessment subject. Seeing the interest in learning in student assignment techniques in solving problems with SPDLV Mathematics learning questions, students were given an assessment questionnaire on how the teacher applied Mathematics learning. The results of this study indicate that there is an increase in student interest in learning, The increase in research resulted in 11 highest numbers of learning interest, 21 moderate numbers and 3 were in the lowest numbers in student interest in learning. From the results of this study the researchers succeeded in suppressing the lowest number and increasing the highest number of students' understanding and interest in solving problems in learning mathematics. The results of the student's interest in learning obtained an increase in interest in learning by 6.58% in MASS PP IRSYADUL ISLAMAH.]]>

<![CDATA[The purpose of this study was to determine students' mathematical connection abilities in the application of problem-based learning models and to determine the effect of student learning using problem-based learning models at SMP Negeri 1 Rantau Utara. The research method used is quasi-experimental research, The population in this study were all students of class VIII SMP Negeri 1 Rantau Utara for the Academic Year 2021/2022 as many as 288 people, then from 8 classes, two classes were selected as samples, namely class VIII-2 which consisted of 36 students who were taught by problem-based learning model, class VIII-5 consisted of 36 students who were taught by conventional learning model.The analytical technique used is descriptive analysis to describe student activities, teacher's ability to manage learning, and student response processes. The results of the analysis of the Gain data for the problem-based learning model class with the conventional model class using the t-test obtained the value of tcount= 8,54 from the distribution list t for = 0,05, and dk = n1 – n2 – 2 or dk = 70 obtained ttable= 1,959. By comparing between ttable and tcount obtained tcount > ttable then Ha is accepted. Thus, the results of this study can be stated that there is an effect of problem-based learning models on increasing students' mathematical connection abilities.]]>

<![CDATA[This study aims to determine whether the learning outcomes of students who are taught with the Problem Based Instruction learning model on reasoning abilities in learning mathematics are better than the learning outcomes of students who are taught without the Problem Based Instruction learning model on the subject of the Pythagorean Theorem. The population of this study were all grade IX students of SMP Negeri 1 Rantau Utara. The research sample was taken by random sampling as many as two classes, namely the experimental class and the control class. The experimental class was treated with the Problem Based Instruction learning model for class IX-1, amounting to thirty-two, while the control class was taught using the Conventional model for class IX-3, amounting to thirty-two.The data used are student learning outcomes collected using tests that have been tested for validity, reliability, level of difficulty and differentiating power. The data obtained were analyzed by one-sided t-test after being tested for normality and homogeneity. From the research, the average pretest value for the experimental class was 44.22 and the control was 43.91, while the average post-test value for the experimental class was 79.53 and the control was 65.00. There are pretest and posttest data for each class, then the gain is calculated, by first testing the normality and homogeneity. From the calculation of the average gain, an increase in student learning outcomes was obtained. The results of the calculation on the t-test based on the students' mathematical reasoning ability obtained thit = 8.26 and ttable = 1.699 at the significance a= 0.05 with dk = 62. These data indicate reasoning ability students' mathematics with the PBI learning model is better than the conventional learning model.This means that tcount > ttable, thus Ho is rejected and Ha is accepted. So it can be concluded that the learning outcomes of students who are treated with Problem Based Instruction learning model on reasoning abilities in mathematics learning are better than learning with conventional models on the subject of the Pythagorean Theorem.]]>

<![CDATA[This study aims to determine the effect of learning media and teacher supervision on student achievement in class X SMA Kemala Bhayangkari. The research method used in this study is a quantitative method with the class action method. The population in this study were all students of SMAS BHAYANGKARI 2 RANTAUPRAPAT class X-IIS-1 and X-MIA-1, totaling 50 students divided into two classes, namely class control and experimental class. The sampling technique used is probability sampling using cluster sampling (area sampling). The instrument and data collection technique used in this study is a multiple-choice test to measure student achievement. The data analysis technique used is descriptive quantitative with descriptive statistics such as descriptive analysis, normality test, paired sample t-test, independent sample t-test on the results of pre-test and post-test then presented in the form of tables and graphs. Based on the results of the analysis, it is known that the average value of student learning outcomes before and after the application of learning media and teacher supervision on student achievement is 42.56 and 50.56% to 79.16% and 71.44%, respectively. The difference in student learning outcomes between the experimental class and the control class is 15.72% and the effect of learning media and teacher supervision on the learning achievement of class X students at SMA Kemala Bhayangkari is 36.6% and the ratio of improvement between the experimental class and the control class is 7.72%.]]>
