The City

In the 2019 survey, 82.2% of teachers never participated in media training, especially learning media based on geogebra technology. Meanwhile, 92.8% of teachers stated that mathematics requires learning media. The low quality of education in NTB requires special attention from both the government and the private sector, so it is important to conduct technology-based learning media training in order to improve the quality of education, especially improving the quality of teachers. The training was carried out using offline and online methods for two days, 19 and 20 August 2021 at SMPN 16 Mataram. The training was attended by 22 participants from junior high school mathematics teachers in the city of Mataram. In the implementation of the training, an evaluation was carried out using questionnaires and observations. The conclusions from the results of the service were as follows: Geogebra training as a medium for learning mathematics for SMP teachers in the city of Mataram in 2021 received a very good response and was well received by the teachers. Geogebra training as a medium for learning mathematics for junior high school teachers in the city of Mataram in 2021 is very in line with what is expected by mathematics teachers in the City of Mataram and increases teacher competence in the context of applying technology in learning to develop technology-based mathematics learning media.

Before And After

Learning mathematics is not only aimed at developing mathematical cognitive abilities, but also for developing affective domains. One important aspect in the affective domain that is very influential and determines success in learning mathematics is the positive view of students on mathematics or in mathematics learning called mathematical disposition. A student who has a high disposition will be more persistent and resilient in facing mathematical problems that are more challenging and will be more responsible for their own learning and always develop good habits in mathematics. The problem posing approach which in the learning process requires students to ask questions and make their solutions is expected to be able to change students 'views of mathematics to be more positive, while also improving students' mathematical abilities. This study aims to examine the differences in the levels of mathematical disposition of junior high school students before and after learning through the problem posing approach. The type of research is experimental research with the design of one group pre-test post-test design. The population in this study were all VII grade students of Bandar Baru 1 Junior High School, with research samples of class VII2 students selected through random sampling techniques. The instrument used to obtain the research data was a mathematical disposition scale questionnaire sheet. The statistical test used to analyze data on differences in mathematical disposition of junior high school students before and after learning through the problem posing approach is paired t-test. The results showed that there were significant differences in the level of mathematical disposition of junior high school students before and after learning through the problem posing approach. This means that students' mathematical dispositions get better after they get a problem posing learning approach. Keywords: Mathematical Disposition, Problem Posing Approach

. The purpose of the study are: 1) find a description of the factors causing low mastery of basic math competency Junior high school students in the Bengkulu City. 2) Generate a valid mathematical model of learning, practical and effective way to improve the competence of Junior high school (SMP) students in the Bengkulu City. To achieve this goal done two phases the first phase is a quantitative and qualitative research (mixed) by applying documentation studies, focus group discussions, in-depth interview and classroom observation. The second phase is the development by implementing Research Design Development (Plomp& Nieveen , 2007) to generate alternatives valid mathematical model of learning, practical and effective to improve the competence of learners in mathematics learning in junior high schools in the Bengkulu City. Results of this study were 1) The factors causing low competence junior high school students in learning mathematics in the Bengkulu City are as follows: Education Management Systems and Learning Mathematics: mathematics learning management tend to be rigid and mechanistic; Teacher: Teachers of Mathematics Having Lesson Planning Document, but in the implementation of learning is not in accordance with the plan that is prepared; Teachers deliver learning materials more emphasis to achieve the target of the curriculum, not to achieve competence, by reason of the allocation of time, and catch-material for students dealing with the national assessment (UN); Media Learning Mathematics: The utilization of instructional media, facilities and infrastructure to support the learning of mathematics has not been used optimally; Model Learning / Learning Strategies: Teachers in the communication of such materials using learning shekel: Presentation of lecture material with the form of definition, and the formula, then the teacher gives examples of problems, followed by exercises and the provision of home tasks, and so on is done repeatedly. 2) Mathematics Learning Model SMP (MPM-SMP) Prototype Devices Learning as one of the supporting system of the learning model is valid, and practical, yet effective for improving the competence of junior high school students in the city of Bengkulu is still in the process of tabulation and analysis of data.

This study titled as The Effect of Disposition on Student Mathematics Learning Achievement in Medan State 28 Junior High School. In this study, disposition is an independent variable and achievement in mathematics learning is a dependent variable. Mathematical disposition is a change of student’s tendency in assuming and behaving toward mathematics, also their act when learning mathematics. For example, when students can solve non-routine problems, their behavior and assumption of mathematics as a student become more positive. The more mathematical concepts understood, the more students convinced that mathematics can be mastered. Based on theory, there are many factors that influence student's achievement in mathematics learning. In this study, researcher only took disposition factor. This research took place at Medan State 28 Junior High School which located at Karya Bersama St. No. 17 Medan Johor. The method of this study is a quantitative method with all of VIII class students which amount to 273 students and divided into 8 (eight) study groups. The data obtained by giving a questionnaire consisting of 19 statements. The data then analyzed by using simple linear regression analysis. The data analysis was performed by using SPSS 21 software for Windows. From the results of this study, it can be concluded that there is an effect of disposition on students' achievement in mathematics learning or in other words, students' achievements in mathematics learning are influenced by the disposition attitudes that students have in mathematics learning. The influence occurs in the disposition of achievement in mathematics learning is positive, that is equal to 6.6%.Keywords: Disposition, Mathematics Learning Achievement.

The purpose of this study is to identify the constraints and problems faced by teachers in junior high school mathematics learning. The subjects in this study were mathematics teachers from ten junior high school level in Pidie Jaya district, amounting to 15 people with purposive sampling. This type of research is descriptive qualitative. The research data was obtained from the results of MGMP activities (Subject Teacher Consultation) with two categories, namely material that was difficult to teach, and a difficult learning process for certain material. The results of the study show that some material that is difficult to teach is the sequence and series, congruence, statistics, algebra (rank in roots), geometry, opportunities, and equations and linear inequalities. For the learning process that is felt difficult for certain materials, namely Algebra (KPK, FPB and SPLDV), Series / pattern numbers, congruence, not actual rank, comparison, flat build, and statistics. Keywords: constraints, problems, learning mathematics, difficult material
