Abstract

Penelitian ini bertujuan untuk mengetahui jenis kesulitan yang dialami peserta didik, bentuk scaffolding yang diberikan, dan kemampuan peserta didik setelah diberikan scaffolding dalam memecahkan masalah soal cerita matematika. Materi yang digunakan adalah sistem persamaan linear tiga variabel (SPLTV). Penelitian ini dilakukan di kelas X SMA Al Ma’arif NU Sinah Pengembur pada semester ganjil tahun ajaran 2021/2022 dengan subjek yang terdiri dari 15 peserta didik. Jenis penelitian ini adalah penelitian deskriptif kualitatif. Data yang dikumpulkan berupa hasil tes diagnosis, hasil wawancara, proses scaffolding, dan tes kemampuan memecahkan masalah. Kesulitan yang dialami peserta didik diantaranya: 1) memahami masalah (menentukan apa yang diketahui dan ditanyakan pada soal); 2) merencanakan penyelesaian (membuat model matematika); 3) menyelesaikan permasalahan (mengoperasikan model matematika); 4) memeriksa kembali (memeriksa kebenaran jawaban termasuk menarik kesimpulan). Ditinjau dari tahapan pemecahan masalah menurut Polya scaffolding yang diberikan disesuaikan dengan letak kesulitan dalam memecahkan masalah soal cerita yaitu; pada tahap memahami masalah scaffolding yang diberikan ialah explaining, reviewing dan restructuring), pada tahap merencanakan penyelesaian dan menyelesaikan permasalahan yaitu reviewing dan restructuring. Sedangkan pada tahap memeriksa kembali scaffolding yang diberikan ialah explaining, reviewing, restructuring, dan developing conseptual thingking. Berdasarkan hasil analisis tes kemampuan memecahkan masalah kemampuan peserta didik dalam memecahkan masalah soal cerita matematika setelah diberikan scaffolding rata-rata nilainya adalah 73,75 yang termasuk dalam kategori baik.

Abstract

Connecting mathematical concepts is one of the abilities that every student should have. Being able to connect between concepts or principles in mathematics can help students in solving every math problem. This study aims to describe the type of errors in connecting mathematical concepts to the number pattern material made by students and to find out the factors of the error made. The subject of this study was students of class VIII at MTs Dakwah Islamiyah Putra Nurul Hakim Kediri in academic year 2018/2019. The type of this research is qualitative research with descriptive approach. Students’ error data obtained from the results of students’ written test and interviews. The results showed that the students made errors in connecting the concepts of number pattern material such as: 1) Errors in connecting topics which is in number pattern material. 2) Errors in connecting topics of number pattern material with other mathematical materials. 3) Errors in connecting number pattern material with the real-life problems. In addition, the factors which cause students made these errors such as: students did not understand the facts in the questions, students did not understand the concept of number pattern, students did not master the principle of number pattern, students did not master in mathematical operations and students were not careful in answering questions.

Abstract

This study aims to determine the effect of the WhatsApp-assisted realistic mathematics learning model (PMR) on the mathematics learning outcomes of seventh grade students of SMPN 13 Mataram in the 2021/2022 academic year. This type of research is a quasi-experimental study with Posttest Only Control Group Design which is a form of research method. Experiment. The population in this study were seventh grade students of SMPN 13 Mataram, the sample technique used was cluster random sampling. The samples of this study were students of class VII (I) as the experiment class and class VII (J) as the control class with a total of 33 students. The instruments used are lesson plans and student learning outcomes test sheets (posttest) on the set material. The data analysis used was the t test to see differences in learning outcomes, and the effect size test to see how much influence the realistic mathematics learning model (PMR) had on students' mathematics learning outcomes. Based on the results of the posttest data analysis using the t-test, it was found that t_count = 2.1457 > t_table = 1.1998 with a significant level of 5%, so H_0 was rejected and the effect size test was d = 0.5408 (medium). So it can be concluded that learning using the realistic mathematics learning model (PMR) assisted by WhatsApp has a significant effect on the mathematics learning outcomes of seventh grade students of SMPN 13 Mataram in the 2021/2022 academic year.

Abstract

Utilization of technology, information and communication, especially the use of software such as Microsoft Word, Microsoft Power Point and Microsoft Excel is an ability that must be possessed by elementary school teachers in implementing an independent curriculum. The use of Microsoft Excel, for example, can assist teachers in processing various data, such as processing assessment instruments in the form of end-of-semester assessment questions for students. Based on interviews with the group leader V Lingsar, the results showed that teachers still needed time in making final semester assessment questions, starting from making question banks, sorting and randomizing questions into several question packages. To answer these problems, a service activity was carried out in the form of training on the use of Microsoft Excel to create a question bank. The training was attended by 20 teachers of the V Lingsar group. This activity consists of two sessions, namely the delivery of material and guided practice. All participants felt that the material could be understood well, guided practice could be carried out smoothly and this activity could be relevant to the needs of the teacher.

Abstract

This research aims to find out the mistakes made by students and the factors that cause mistakes made by students in solving algebraic form problems in terms of Polya steps. This type of research is descriptive and qualitative. The sample used was 28 students with the sampling technique used being proportionate stratified random sampling. Data collection techniques are carried out by tests and interviews. Based on the analysis of student test results, error were obtained by students in each question item, namely, errors in understanding the problem, errors in drawing up plans, errors in implementing plan, and errors in re-examining. The results showed that the percentage of mistakes made by students in the whole question was 44% errors in understanding the problem with sufficient categories, 36% errors in drafting plans with low categories, errors in implementing plan by 33% with low categories, and errors in re-examining by 61% with high category. The cause of students' mistakes in solving algebraic form questions is that students are not careful in reading the questions and in writing down their work, do not understand the questions or prerequisite materials, both the nature, formulas, or procedures for working on the questions, the desire to answer briefly to things that are known and asked. As well as students are not used to re-examining.
