<![CDATA[This research is motivated by the lack of understanding of students in learning mathematics. So that the Problem Based Learning approach was chosen by means of peer tutor discussions. The research process was carried out in three cycles, where each cycle includes 4 stages, namely: 1) the student orientation stage on the problem 2) the student organization stage, 3) the stage of guiding the investigation, 4) the stage of developing the work, 5) the analysis and evaluation stage. Data was collected by purposive sampling, namely 10 students of class XI SMK Karya Bhakti Pusdikpal. Technical analysis of the data is seen from the learning outcomes or the scores obtained from three cycles with a minimum limit of 85% reaching the KKM score of 75. The results obtained from the implementation of the research show an increase, where the student's score has increased from an average of 64.5 to 81.4 and becomes 85.6. Therefore, it can be concluded that the application of the Problem Based Learning Method by means of peer tutor discussions can improve students' mathematics learning outcomes and teachers should use this method to increase student activity in understanding the concepts of mathematics learning.]]>

<![CDATA[The purpose of this study is to analyze the increase in understanding of mathematical concepts in quadratic equations. The method used is Classroom Action Research with the stages of research using the Taggart model. The subjects in this study were class IX students at MTs An-Nur Cikalongwetan with a sample of 15 students. Data collection techniques using test and non-test instruments. The test instruments used were pretest and posttest with indicators of understanding students' mathematical concepts. The non-test instrument was in the form of a questionnaire related to student learning independence. Data analysis using descriptive qualitative with tests processed using N-Gain, while the non-test is processed using a Likert scale. Based on the N-Gain analysis, it was concluded that there was an increase in students' understanding of mathematical concepts from the results of the students' pretest and posttest with a total percentage of 62.3% with quite effective criteria. Student learning independence is at an average percentage of 61.04% with strong criteria.]]>

<![CDATA[In this study using classroom action research. The goal is to find out information on the application of the discovery learning model to online learning of set materials to improve the learning outcomes of junior high school students. With the implementation of research on class VII-E students at one state junior high school in Cimahi City, totaling 37 people. This class action research is carried out in 2 cycles, where each cycle has 2 meetings. The research instrument uses observations, study test results, and journals conducted online. Analyze the data in the form of average and percentage results with descriptive statistics. The average score of 71.64 with a percentage of 56.75% is the learning outcome of students in the first cycle and the average score of 80.74 with a percentage of 86.48% is the learning outcome of students in cycle II. The activities of teachers and students in each cycle in online learning are quite good and effective but there is something that needs to be improved in student activity during the online learning process. It is concluded that there is an increase in student learning outcomes in online learning, so the discovery learning model can be applied to class VII students of the set material.]]>
