Abstract

This study aims to describe the factors that caused the fear of class VIII students to fail in learning mathematics at Baubau State Middle School 18. This research is a qualitative descriptive study. The data sources in this study were VIII grade students at Baubau 18 Public Middle School who had a mathematical value of ≤ 65 and the sample used was taken by Cluster Random Sampling technique. The research instruments used in the study were observation sheets, questionnaire sheets, and interview guidelines. Data collection techniques were carried out through observation, questionnaires, and interviews. The data analysis technique used in this study is data reduction, data display, and conclusion. The results of the study showed that i.e. (1) the factors of associating friends, obtained a percentage of 81.08% indicating that the factors of associating with the emergence of fear of students' failure to learn mathematics were classified as very high; (2) teacher factors obtained percentage of 80.71% which is also classified as very high; (3) Factors related to self-motivation obtained a percentage of 70.92%, this shows that self-motivation factors towards the emergence of fear of students will fail in learning mathematics, relatively high.AbstrakPenelitian ini bertujuan untuk mendeskripsikan faktor-faktor penyebab timbulnya rasa takut siswa kelas VIII akan kegagalan dalam mempelajari matematika di SMP Negeri 18 Baubau. Penelitian ini merupakan penelitian deskriptif kualitatif. Sumber data dalam penelitian ini adalah siswa kelas VIII di SMP Negeri 18 Baubau yang memiliki nilai matematika  dan sampel yang digunakan diambil dengan teknik Cluster Random Sampling. Instrument penelitian yang digunakan dalam penelitian adalah lembar observasi, lembar angket, dan pedoman wawancara. Teknik pengumpulan data dilakukan melalui metode observasi, angket, dan wawancara. Teknik analisis data yang digunakan dalam penelitian ini yaitu reduksi data, display data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa (1) faktor teman bergaul, diperoleh presentase sebesar 81,08% menunjukkan bahwa faktor teman bergaul terhadap timbulnya rasa takut siswa akan kegagalan dalam mempelajari matematika tergolong sangat tinggi; (2) faktor guru diperoleh presentase sebesar 80,71% yang juga tergolong sangat tinggi; (3) Faktor yang berkaitan dengan motivasi diri sendiri diperoleh presentase sebesar 70,92%, hal ini menunjukkan bahwa faktor motivasi diri sendiri terhadap timbulnya rasa takut siswa akan kegagalan dalam mempelajari matematika, tergolong tinggi.

Abstract

One of the goals of mathematics learning mentioned by NCTM is to become a mathematical problem solver. This indicates that students who study mathematics will have problem-solving abilities. In solving problems the things that need to be considered in learning are more about the process than the final result. If the final answer is emphasized, students can only learn one particular problem Furthermore, the important mathematical material is a two-variable linear equation system because the learning process in SPLDV requires good mastery of the material in problem solving, so from here it is necessary to design learning in order to formulate precisely the learning patterns that will be carried out by the teacher to students. This research uses design research method at the preliminary design stage which is arranged by considering students' ability to solve a mathematical problem at SMPN 1 Sampolawa, because each student has a different way of thinking between one student and another student. The flow of students' thinking that might appear in learning is called the hypothetical learning trajectory. In this article will explain the Hypothetical Learning Trajectory (HLT) in students' problem solving activities material systems of linear equations of two variables.AbstrakSalah satu tujuan pembelajaran matematika yang disebutkan oleh NCTM yakni menjadi problem solver matematika. Hal ini mengindikasikan siswa yang mempelajari matematika akan memiliki kemampuan pemecahan masalah. Dalam memecahkan masalah hal yang perlu diperhatikan dalam belajar adalah lebih mengutamakan proses dari pada hasil akhir. Jika jawaban akhir yang ditekankan maka siswa hanya dapat belajar satu masalah tertentu Selanjutnya materi matematika yang penting adalah sistem persamaan linear dua variabel (SPLDV) ini dikarenakan proses pembelajaran pada SPLDV memerlukan penguasaan materi yang baik dalam pemecahan masalah, sehingga dari sini diperlukan desain pembelajaran agar dapat merumuskan secara tepat pola pembelajaran yang akan dilakukan oleh guru kepada siswa. Penelitian ini menggunakan metode design research pada tahap preliminary design yang disusun dengan mempertimbangkan kemampuan siswa dalam menyelesaikan suatu masalah matematika di SMPN 1 Sampolawa, karena tiap siswa memiliki cara berpikir yang berbeda antara siswa satu dengan siswa yang lain. Alur berpikir siswa yang mungkin muncul dalam pembelajaran dinamakan dengan hipotesis lintasan belajar atau hypothetical learning trajectory. Dalam artikel ini akan memaparkan Hypothetical Learning Trajectory (HLT) dalam kegiatan pemecahan masalah siswa materi sistem persamaan linear dua variabel.

Abstract

This study aims to determine the effect of active learning on student learning outcomes in mathematics at Waruruma Elementary School Class IV for the 2020/2021 academic year. This research is an Ex-post Facto research. The population in this study were all fourth grade students of Waruruma Elementary School which consisted of 2 classes with a all of 41 students. The sample used in this study was the entire population of 41 students. The instruments used are in the form of questionnaires and documentation, where the documentation is the students mid semester test. From the results of descriptive analysis of the data shows that the level of students learning activity in general is still in the medium category. Where as many as 19,51% of students are in the high category, as many as 65,85% of students are in the medium category and as many as 14,63% of students are in the low category. As for the level of students’ mathematics learning outcomes in the high category. Where as many as 51,22% of students are in the high category, as many as 34,15% of students are in the medium category and as many as 14,63% of students are in the low category. The results of the study concluded that it showed that learning activity had an effect on student learning outcomes in Mathematics for Class IV at Waruruma State Elementary School for the 2020/2021 academic year. This is indicated by a significant value of 0,00 < 0,05.
