<![CDATA[This study intends to investigate and learn about the improvement of mastery of the concept of Relations and Functions in Grade VIII students of SMP Negeri 28 Bandung. The hypothesis of this research action is that via scientific approach, the mastery of the idea of Relation and Function of Grade VIII Students of SMP Negeri 28 Bandung may be improved. With a total of 32 students, this study was conducted on grade VIII students at SMP Negeri 28 Bandung in the 2020/2021 school year. The instrument utilized is a learning outcomes test that assesses students' mathematical concept skills. Initial tests (before action), cycle I and cycle II tests (after actions), and observation sheets for teachers and students are all examples of testing. Planning, action implementation, observation and assessment, and reflection are all part of this study approach. The data processing technique in this study is to find the average value by using Microsoft Excel. Cycle I's average test score was 73.86, up 18.21 points from the average beginning test result of 55.65. The average score of cycle II test results was 82.45, up 26.8 points from the average initial test result and 8.59 points higher than cycle I test results. The mastery of the idea of Relationships and Functions in grade VIII students of SMP Negeri 28 Bandung can be improved using a scientific method, according to work indicators.]]>

<![CDATA[Professional teachers are one of the determining factors in the success of teaching and learning in the classroom. Designing quality learning tools is the readiness of the teacher to teach. Teacher professionalism is an absolute requirement for the realization of the objectives of national education. Efforts to develop teacher competency should be carried out comprehensively and continuously Improving the quality, capacity, pedagogical-professional competence and fostering the teaching profession (in this case teachers), especially in MTs Cahaya Harapan Cisarua can be done through Lesson study activities. Lesson study is a model of teacher professional development through teaching and learning (learning assessment) collaboratively with a continuous and cycle system based on the principles of collegiality and mutual learning to build learning communities. The basic concept of implementing Lesson Study includes three activities namely; plan-do-see, namely: (1) Planning (planning). (2) Implementation (action) or learning and observation. (3) Reflections on the planning and implementation of the learning. The response of the participants was enthusiastic about this lesson study training.]]>

<![CDATA[The focused research aims to study the improvement of students' mathematical understanding skills through discovery learning models on fractional numbers. The implementation is applied to smpn 2 Bojong students who focus on class VII in the 2021/2022 school year as many as 25 people. The required test instrument is a mathematical comprehension ability test of 6 descriptions. The research was conducted in a series that contains two cycles with two encounters in each cycle. The final data of completion is analyzed based on the quality that goes through the phases consisting of: 1. Accumulated data, 2. Data shrinkage, 3. Data submission, and 4. Summary. The non-test assessment used is a scale of learning independence attitudes. The impact of the first cycle of research shows that students are still passive and learning is not effective because learning is solidified. In the pretest results, the average value is 39 which is still far from the KKM value of 70. After analysis, many students of class VII A still do not understand the concept of fractional number operations. At the end of the implementation of PTK, postes were carried out which had an average value of 78.4.]]>

<![CDATA[This research is included in classroom action research or classroom action research to examine efforts to increase students' motivation and learning outcomes after being rewarded. The hypothesis is that the method of giving rewards can be one of the efforts to increase motivation, which impacts student learning outcomes in series and sequence material in distance or online learning in class XI SMK students. The research instrument for class XI RPL-A SMK Pusdikhubad Cimahi in the 2020/2021 period was 34 people. Researchers used an instrument with an ability test to measure student learning outcomes and a questionnaire to measure their learning motivation. The data analysis technique used is the initial data analysis or requirements test which consists of normality test, homogeneity test. Then the final data analysis was carried out in the form of normality, homogeneity, T-Testm, N-Gain, and Treatment tests. Researchers found an increase in learning motivation and learning outcomes for class XI SMK students in online or online learning in the subject "Barisan dan Deret." This is indicated by the percentage of students' motivation scores and learning outcomes in cycles I and II. Student learning motivation in cycles I and II, namely 2.92 and 4.22, means an average increase of 1.30. And for student learning outcomes in cycles I and II, namely 52.94% and 79.41%, which means there is an average increase of 26.49%.]]>

<![CDATA[This study aims to evaluate how students of class XI TKR 2 SMK Nurul Hidayah Pasundan develop their mathematical problem-solving skills using a problem-based learning technique on the topic of matrix determinants. This research is a classroom action research. The 2021–2022 school year's odd-numbered semester was employed for this study. There were 15 students of class XI TKR 2 who were used as research subjects. The following are the steps in this research: (1) Planning, (2) Action Implementation, (3) Observation and Evaluation, (4) Reflection. A learning outcome assessment used in this study measures students' ability to solve problems in relation to the determinants of the matrix., that is: (1) initial test, (2) first cycle test and second cycle test, (3) final test, and ( 4) observation sheets for researchers and students. The learning scenario had to be met by more than 80% of the activities performed in this study, and more than 80% of the individual students had to receive a score of at least 75. According to the study's findings, students in class XI TKR 2 at SMK Nurul Hidayah Pasundan can increase their capacity to solve mathematical problems by employing a problem-based learning approach when studying matrix determinants.]]>
