Abstract

Discovery learning is a learning model that is useful for developing students' mathematical reasoning skills. This research aims to develop E-LKPD based on discovery learning that are valid, practical, and effective. This research uses the ADDIE approach (Analysis, Design, Development, Implementation, and Evaluation). Product testing carried out included limited field trials to 10 students and extensive field trials to 24 students of SMP Negeri 1 Gondanglegi, Malang Regency. Data collection techniques utilize expert validation sheets, E-LKPD practicality questionnaires, and mathematical reasoning test sheets. The product validity tests conducted by experts (material, learning, and media experts) are declared valid with a score of 3.44. The product practicality test's results based on student responses obtained a score of 3.42 so it’s declared practical. The product effectiveness test's results obtained a completeness percentage of 70.8% and declared effective in learning activities. Students' reasoning ability is said to improve based on their test results. This study concludes that the E-LKPD based on Discovery Learning is valid, practical, and effective and can improve the students’ mathematical reasoning ability. It’s hoped that the E-LKPD developed used as mathematics teaching materials.

Abstract

The background to this research is based on observations of students at SMP Negeri 6 Lembor, East Nusa Tenggara, where mathematical critical thingking abilities were still low. Data collection techniques include test results, interviews, and documentation. This data collection used critical thingking ability tests and interviews with twenty students from class 7B, even during the semester of the 2021/2022 academic year. Data analysis techniques use data reduction, data presentation, and concluding students' critical thinking skills in solving mathematical problems using the Blended Learning approach. The results showed that students with critical thinking skills in the 'low' category were only able to fulfill one indicator and did not fulfill all of them because they had not been able to understand the meaning of the problem, formulate concepts, write solutions, and draw conclusions properly and correctly. Students with 'medium' critical thinking skills can meet 2 to 3 indicators because they can only choose the right solution strategy but are still wrong and make mistakes in their calculations. In contrast, students with 'high' critical thinking skills meet all ability indicators—critical thinking. Because students can choose a solution strategy and give reasons related to the chosen strategy wholly and correctly, it can be concluded that as many as 80% can think critically in the 'low' category, as much as 10% can think critically in the 'medium' category, and 10% can think critically in the 'high' category.

Abstract

The purpose of this study is to analyze mathematical problem-solving abilities based on Polya's steps and the causes of students' errors in solving mathematical problems. The problem-solving stage consists of 4 stages, namely the stage of understanding the problem, planning a solution, carrying out a solution plan, and looking back. This study used 6 subjects from 25 eighth grade students of SMP Terpadu Turen. Data collection is done by tests and interviews. Data validity test is done by triangulation technique. The results of this study were (1) at the stage of understanding many students, they did not experience difficulties because students were able to understand the problem, (2) at the planning stage there were some students who did not write the completion plan but understood the way they would do to solve the problem but they were not used to write down the plan, (3) at the stage of carrying out the plan there were some students who have difficulty because they are less thorough so that they are not aware of the mistakes made. This is because students lack concentration in solving problems, (4) at the stage of looking back there are students who have not reached this stage because they have not completed the previous stage.

Abstract

This study aimed to describe the errors that student made in completing the Two Variable Linear Equation System based on Watson's criteria. This was a descriptive qualitative study involving 29 students consisted of of 12 high-skilled students, 5 medium-skilled students, and 12 low-skilled students in 8th grade at SMP PGRI 6 Malang. The data were obtained from the types of errors that student made using the Two Variable Linear Equation System question tests and the results of the interviews based on the Watson's criteria indicators. The question sets used in this study had been verified by mathematics education lecturers and mathematics teachers. The results of this study were: a) high-skilled students were 'less thorough' at work; (2) medium-skilled students were ‘using data incorrectly at the early stages'; while (3) low-skilled students ‘did not give answers' because they did not understand the concepts of the learning materials. The three types of errors frequently made by students were errors in determining the operation to be used (mhk), errors in determining the stages of solving the question problems (mtl), and errors in drawing conclusions from the final results (kh).

Abstract

Desa Candiwates berpotensi sebagai desa wisata. Akan tetapi, masyarakat setempat belum memiliki keterampilan pembuatan sovenir bagi wisatawan. Kegiatan abdimas ini bertujuan untuk mengembangkan keterampilan membuat batik ikat celup yang akan digunakan sebagai sovenir. Mitra kegiatan ini adalah kelompok PKK Desa Candiwates. Peserta kegiatan sebanyak 15 orang yang merupakan perwakilan dari setiap dusun. Kegiatan abdimas berupa pelatihan dan pendampingan untuk meningkatkan keterampilan menciptakan karya inovatif berupa batik ikat celup yang dapat menjadi peluang berwirausaha. Selain itu, kegiatan ini untuk pemberdayaan anggota kelompok PKK. Kegiatan abdimas dilakukan melalui pelatihan dengan metode ceramah dan pemberian contoh serta pendampingan berupa kegiatan praktik. Hasil evaluasi menunjukkan bahwa mitra pengabdian 100% memahami teori dan dapat mengimplementasikannya. Akan tetapi, 70% kualitas corak batik ikat celup masih belum inovatif dan kreatif. Motivasi dan semangat peserta pelatihan sangat tinggi. Seluruh peserta menyatakan senang dan puas dengan kegiatan ini karena memberikan pengetahuan dan aktivitas yang bermanfaat. Hasil abdimas ini diharapkan membuka kesempatan berwirausaha bagi peserta yang ingin mengembangkan ilmu dan keterampilannya, sehingga dapat meningkatkan pendapatan keluarga. Kegiatan ini akan ditindaklanjuti dengan pengembangan keterampilan mengolah kain batik ikat celup menjadi produk lain, seperti: taplak meja, baju, dompet, dan sebagainya.

Abstract

Abstract: This study explores the effectiveness of the Polya Problem Solving Method in improving students' ability to solve word problems in mathematics at SMPN 17 Malang, Indonesia. The main objective is to determine whether this method can improve students' problem-solving abilities in the context of a linear equation system with two variables. A Classroom Action Research (CAR) approach is used, with two implementation cycles. Data was collected through pre- and post-test tests, classroom observations, and student interviews. These findings show a significant improvement in student performance, with the percentage of students meeting the Minimum Completeness Criteria (MCC) increasing from 36.3% in the pre-test to 84.84% after Cycle II. In addition, student engagement and teacher effectiveness increased markedly, especially in the second cycle, highlighting the importance of personalized support and active learning strategies. The results show that the Polya method can be very effective in fostering critical thinking and problem-solving skills in mathematics. This study contributes to the existing literature by demonstrating the benefits of structured problem-solving methods in Indonesian secondary education. Further research is recommended to explore the long-term effects of this method and its application in different educational contexts.
