Abstract

Penelitian ini bertujuan untuk menghasilkan Lembar Kerja Peserta Didik (LKPD) berbasis Problem-Based Learning (PBL) pada topik sudut yang layak. Penelitian pengembangan ini mengadopsi model pengembangan ADDIE dengan tahapan meliputi Analysis, Design, Development, Implementation, dan Evaluation. Kualitas LKPD ditinjau dari penilaian ahli materi, ahli media, dan respon peserta didik. Instrumen penelitian yang digunakan adalah angket ahli materi, angket ahli media, dan angket respon peserta didik. LKPD diujicobakan di kelas VII SMP Muhammadiyah 1 Yogyakarta dengan subjek sebanyak 32 peserta didik. LKPD yang dikembangkan memuat aktivitas pembelajaran sesuai langkah PBL, menyajikan masalah yang berkaitan dengan kehidupan sehari-hari di awal pembelajaran, dan dapat digunakan dalam pembelajaran online. Ditinjau dari aspek materi, LKPD dinilai baik dengan rerata skor penilaian oleh ahli materi yaitu 4,00. Ditinjau dari aspek media, LKPD dinilai baik dengan skor penilaian oleh ahli media sebesar 3,6. Respon peserta didik terhadap penggunaan LKPD termasuk pada kategori baik dengan rerata skor penilaian sebesar 4,05. Dapat disimpulkan bahwa LKPD berbasis PBL untuk SMP kelas VII pada topik sudut layak digunakan dalam pelaksanaan pembelajaran matematika. Development of a students' worksheet based on problem-based learning (PBL) on the topic of anglesAbstractThis study aimed to produce a students’ worksheet or Lembar Kerja Peserta Didik (LKPD) based on Problem-Based Learning (PBL) on the topic of angles, which were feasible. This development research adopts the ADDIE development model with stages including Analysis, Design, Development, Implementation, and Evaluation. The quality of LKPD was viewed from the assessment of material experts, media experts, and students’ responses. The instrument used was a material expert questionnaire, a media expert questionnaire, and a students’ response questionnaire. LKPD was piloted on 32 seventh grade students of private junior high schools, namely SMP Muhammadiyah 1 Yogyakarta, Indonesia. The developed LKPD contained learning activities according to PBL steps, presented problems related to everyday life at the beginning of learning, and could be used in online learning. In terms of the material aspect, LKPD was considered good with an average score of assessment by material experts, namely 4.00. In terms of the media aspect, LKPD was considered good with a score of 3.6 by media experts. Students’ responses to the use of LKPD were included in the good category with an average score of assessment of 4.05. It could be concluded that the PBL-based LKPD for seventh-grade junior high school students on the topic of angles was feasible for use in the implementation of mathematics learning.

Abstract

This investigation aims to examine problem-solving ability (PSA) in Polya's problem-solving phases in the material of sine and cosine number and difference. This study used the descriptive qualitative research method. This study looked at 33 students in Class XI MIPA 5 from SMA Negeri 2 Bantul. Data was collected using written tests and interviews. The written test in this study takes the form of a two-point description question. The study's findings were used to calculate the mathematics PSA of students in class XI MIPA 5 at SMA Negeri 2. In mathematics, the average percentage of students who meet the low requirement is 59.72 percent. Furthermore, children with high expectations can thoroughly, meticulously, and systematically solve difficulties. Understanding the problem remains a struggle for pupils who reach intermediate standards and have yet to complete the problem's solution. Meanwhile, students who scored low on the criteria had trouble understanding the problem and were unable to solve it using the prepared plans, as well as students who were unable to double-check the response and complete the solution to the problem that had been solved.

Abstract

Education is a systematic effort to develop individual abilities in the era of globalization. According to Law Number 20 Article 3 of 2003 education has a strategic function in preparing high intellectual, emotional and social abilities. Thinking ability affects success in learning. Thinking is the process of interpreting circumstances from existing premises. Logical thinking becomes a step in solving complex problems for every individual. Mathematics affects the formation of a mindset. The ability to think logically is based on indicators in making meaning, making logical connections between concepts and facts, grieving and testing concepts, solving problems rationally, and drawing conclusions. The research was conducted on seventh-grade G-class students of Madrasah Mu'allimin Muhammadiyah Yogyakarta using test and interview methods as confirmation. Student work results were analyzed descriptively and grouped into four categories in general and based on indicators. It was found that students' abilities were in the less high category with a percentage of 76.7% and based on indicators the majority were in the less high category. So, it can be concluded that student’s ability to think logically is low.
