Abstract

This research was motivated by the low mathematical problem solving ability of students based on the results of field observations and the results of previous research. This study aims to determine the effectiveness of LKPD assisted by live worksheets with a problem-based learning approach to the mathematical problem solving ability of grade VIII students. The method used in this study is an experimental method with One-Group Pretest-Posttest Design by Sugiyono. The subjects in this study were 30 grade VIII students at MTs Al-Firdaus with low, medium to high categories. The research instrument used in this study was in the form of five description questions adjusted to indicators of problem-solving ability which were then calculated using the SPSS application. Based on the calculation of the comparison of pre-test and post-test values, it is found that the post-test value is greater than the pre-test value. In the pre-test students still have some errors in working on the problems given, while during the post-test few students make mistakes in solving problems. Based on the research conducted, it can be concluded that LKPD assisted by live worksheets with a problem-based learning approach is effective in improving the mathematical problem solving ability of grade VIII students, especially on the Pythagorean theorem material.

Abstract

This research is an experiment which aims to examine improving the mathematical communication skills and interest in learning of junior high school students in set material by implementing the reciprocal teaching learning model. The problem behind this research is that students' mathematical communication skills and interest in learning in set material are still in the low category, so learning alternatives are needed that can develop students' mathematical communication skills and interest in learning. The research method used is Pre-Experimental with a one group pretest-posttest research design. The population in this study were all class VII students in one of the private junior high schools in Karawang Regency. The sample in this research was 25 students with a purposive sampling technique. The instrument used is a communication skills test and a non-test in the form of a learning interest questionnaire. Based on the analysis of the data obtained, it shows that students' mathematical communication skills after implementing the reciprocal teaching model are better, namely from 8.32 to 75.32 and students' interest in studying set material after using the reciprocal teaching model is 60% in the low interest category and 40% with the high category which was previously 32% in the very low category and 68% in the low interest category. Thus, it can be concluded that the application of the reciprocal teaching model can improve the mathematical communication skills and interest in learning of class VII SMP students in set material, although not optimally.

Abstract

Face-to-face learning has been re-implemented by several schools after 2 years offline, and this has caused several obstacles when implementing it. Especially mathematics learning, which tends to require more effort to deliver material. Post-pandemic learning causes didactical obstacles to student and teacher learning during the teaching and learning process. So the purpose of this study is to analyze student barriers to post-pandemic learning. The research method used in this study is qualitative-descriptive, with data collection techniques such as survey methods, observation results, questionnaires, and interviews. The object of this study was 19 grade VIII–4 students and senior teachers at SMP Negeri 1 Cihampelas. This research uses several instruments for students, and the results can be analyzed for obstacles to the post-pandemic learning process. Based on the results of the study, it shows that post-pandemic learning barriers for Grade VIII–4 students are adaptation to a new environment; understanding the material is more difficult and ineffective because the learning process does not involve technology, conventional learning methods, psychological changes, or habits when online learning is still carried over so that it affects face-to-face learning, where students are not ready to get the next material due to the material they previously did not understand due to the lack of maximum understanding of students when learning online. Not only students, but teachers also have their own obstacles when learning after this pandemic, so teachers also need time to be able to adapt to face-to-face meetings that run according to mutual expectations.

Abstract

Communication skill is an ability that needs to be possessed by students. Through communication, students can express their opinions or ideas to their friends or to the teacher. The facts in the field show that students' mathematical communication skills are in the low category, therefore a solution is needed to improve students' mathematical communication skills. This research aims to produce problem-based learning-based LKPD assisted by liveworksheets to hone students' mathematical communication skills. This research was conducted at SMPN 1 Ngamprah. The subjects of this study amounted to 10 students on a limited trial. 34 students for a broad trial. The method used is development research according to Sugiyono which is modified into 7 stages carried out due to time constraints, namely: potential and problems, data collection, product design, design validation, design revision, product trial, and product revision. Data collection tools for this study are validation sheets, student response questionnaires, and 5 questions about mathematical communication skills in statistics material. Based on the results of value processing from validators, it shows that the developed LKPD is said to be suitable for use in learning, with an average percentage of assessment from validators of 85%. The results of the calculation of student answers show that the developed LKPD is effective for improving mathematical communication skills, with an average calculation of each indicator of 72.35%.  It can be concluded that problem-based learning-based LKPD assisted by liveworksheets can be used in learning as an effort to improve students' mathematical abilities in statistics material.
