Abstract

Mathematics is a subject that has an important role in the world of education, but not all students can solve mathematical problems well and correctly. This can be seen from the students' mathematics learning outcomes which are still low, therefore it can be said that the problem-solving process is still considered difficult by students. This research aims to design more effective learning and motivate students to learn to improve their mathematical problem-solving abilities. This type of research is called Classroom Action Research (PTK). The subjects of this research were 20 grade 8 students at one of the Junior High Schools (SMP) in Sungai Rotan District, Muara Enim Regency. This research uses test and non-test data collection techniques. The data analysis stage was carried out with quantitative data, namely from the results of the pre-test and post-test as well as the results of observations in each cycle. In this study, an assessment score of 10-100 was used. Based on the results of research conducted at one of the junior high schools where this research took place, it can be concluded that using the Polya model problem-solving learning method can improve students' mathematical problem-solving abilities.

Abstract

The purpose of this study was to analyze the learning interest of SMK Negeri 1 Prabumulih students on logarithm material through the Teams Games Tournament (TGT) learning model. The research methodology used is descriptive qualitative. Thirty-one students from class X Accounting 2 were selected as research subjects for this study. Questionnaires about students' interest in learning which included 15 positive and negative statements served as the research instrument. Microsoft Excel was used to process data from the answers given by students on the questionnaire. The research findings indicate that students' enthusiasm in learning is 79,76%, which falls into the Strong group, when looking at the average percentage of all indicators. As a result, it can be concluded that the Teams Games Tournament (TGT) learning model on logarithm material was successful in encouraging students in class X Accounting 2 at SMK Negeri 1 Prabumulih to respond positively to their mathematical lessons.

Abstract

The emergence of this research is caused by the low mathematical literacy of students in Indonesia. This study aims to obtain valid, practical, and have potential effects of PISA type questions and activities using social distancing context during pandemic. This study is design research with the type of development studies which consist of two main stages, including preliminary design and formative evaluation. This study took a special research subject for grade IX junior high school students aged 14-16 years in the city of Palembang. Analysis of the results of this study was carried out qualitatively based on data in the field obtained in the form of interviews, photos and videos to see student activities in working on questions and activities. From this study, the results obtained include one type of activity and one evaluation question of the results of developing PISA type questions and activities with the context of social distancing during a pandemic that grade IX students can use to develop their mathematics literacy skills. In conclusion, PISA type questions and activities with the context of social distancing during the pandemic can be used for the learning process in the classroom to improve students' mathematical literacy.

Abstract

This study aims to produce valid and practical PISA-based numerical problems in the context of the pandemic period and to find out the role of the questions in the form of potential effects on the mathematical literacy skills of secondary school students. This research uses developmental research design, which has 2 stages, namely preliminary and formative evaluation (self-evaluation, expert review, one-to-one and small group validation, and field test). The participants in this study were students in Grade 8 who were under the age of 15 and different levels of skills. Data analysis was done descriptively by conducting observations, tests, interviews, and document analysis. The research was conducted face-to-face and via Zoom and WhatsApp Group (WAG) to produce valid and practical PISA-like arithmetic questions. Based on the students' responses, it can be stated that the questions presented are in the practical category because they can be completed quickly by students, they can be understood well by students, and they have the potential effect on students' mathematical literacy skills. In addition, there is a diversity of answers between one student and another according to the level of difficulty that is appropriate for Grade 8 students. This proves that a PISA-like numeration problem in the context of the religious day during a pandemic can help improve students' mathematical literacy.DOI : https://doi.org/10.22342/jpm.16.2.16010.157-170

Abstract

This research aims to describe the results of the analysis of the mathematical communication skills of class This research method is descriptive qualitative research. The subjects of this research were class X AKL 1 students consisting of 30 students consisting of 28 female students and 2 male students. The instrument in this research was to use a test instrument for mathematical communication skills in the form of 3 questions. The results of this research indicate that students' ability to complete mathematical communication skills is still lacking or low. This can be seen from the results of the recapitulation of the overall answers of students who answered correctly as much as 34.4%, answered incorrectly as much as 41.11%, and did not answer as much as 24.4%. Apart from that, it can be seen from the results of the student score conversion that students' mathematical communication skills are in the very low category, namely students who get a score of less than 61%.

Abstract

The very low learning outcomes of students, especially in mathematical communication skills regarding teaching and learning activities, is one source of problems in learning that must be overcome by every teaching staff. This research aims to see an increase in the mathematics communication learning outcomes of students who are taught using a generative model. Classroom Action Research (PTK) or Classroom Action Research (CAR) is this type of research. The subjects in this research were 30 class VIII students at a junior high school in the city of Palembang. The research flow uses the Kemmis and Mc flow. Taggart, the stages in this research are planning, action, observation and reflection which were carried out in two cycles. Data collection took the form of tests to measure mathematical communication skills and questionnaire sheets used to determine learning implementation. From the results of data analysis, the average student learning outcome in cycle I was 72.85 with a student completion percentage of 60%, the average student learning outcome in cycle II rose to 77.65 with a student completion percentage of 83.33%. Meanwhile, the results of the observation sheet show that the implementation of learning activities is going well. The conclusion is that mathematics learning taught by generative models can improve students' mathematical communication skills.
