Abstract

LKPD (Student Worksheet) based on discovery learning  is intended to provide learning knowledge directly in the process of meaningful learning activities so as to direct students to find learning concepts. This study aims to determine the level of feasibility, practicality and effectiveness of LKPD based  on Discovery Learning to train students' critical thinking skills on respiratory system material. Researchers used the R&D (Research and Development) method  using a 4-D development model (Define, Design, Development and Desemminate) developed by S. Thiagarajan, Dorothy S. Semmel, and Melvyn I. Semmel in 1974. The test subjects in the study consisted of 36 students from class XI IPA SMA PAB 4 Sampali. The results showed that the feasibility value of developing LKPD from material experts was 86.1% with the very feasible category and LKPD experts by 75% with the feasible category. Then the percentage of practical scores for LKPD development from biology teachers and students of science XI was 82.14% and 83.47% respectively with the practical category. The effectiveness of LKPD development based on individual completeness from  the pre-test  and post-test students obtained an average N-Gain  score of 62.14, so the use of the method has been effective because the N-Gain normality value obtained between 0.30 < g < 0.70 with the "effective" criterion. Then for the N-Gain score value of 0.62, this value is in the medium category because the N-Gain score is between 0.3-07 with the category "medium N-Gain". From the overall results including valid, practical and effective categories, it can be concluded that LKPD based  on Discovery Learning on the equipment system material is suitable for use and distribution to PAB 4 Sampali High School.

Abstract

Tujuan penulisan artikel ini adalah untuk memberikan pengajaran kepada masyarakat tentang pentingnya olahraga sejak dini, khususnya kepada Siswa SDN 055980 Aman Damai. Penelitian ini menggunakan metode Participatory Action Research (PAR). Yaitu metode penelitian yang bersifat kolaboratif dan transformatif. Diharapkan setelah kegiatan sosialisasi ini para Siswa yang kurang aktif bermain atau lebih terbiasa berdiam diri dirumah dapat lebih aktif dan bersosialisasi dengan anak-anak lainnya dan diharapkan juga agar pertumbuhan anak dapat lebih baik karena Siswa sejak dini telah berolah raga yaitu dengan bermain, berlari, dan meloncat yang membuat tubuh anak lebih aktif dan pertumbuhan tubuh anak juga akan lebih baik yang menjadikan tubuh anak menjadi lebih kuat dalam menempu masa depannya yang akan datang dan masa depan yang cerah akan menyambut generasi mendatang dengan kesiapan fisik dan mental yang kuat.

Abstract

Dalam konsep matematika, etnomatematika merupakan aktivitas pembelajaran yang memasukkkan unsur- unsur budaya seperti lagu daerah,warisan budaya,kue khas tradisional ,tarian daerah,permainan tradisional,rumah adat serta kegiatan sehari-hari lainnya.Suku karo merupakan salah satu suku yang ada di Indonesia,yang memilki beragam keunikan adat istiadatanya yang harus di lestarikan, dan akan semakin unik saat akan di bahas dalam metode matematika,Salah satu budaya suku batak  yang akan di bahas dalam penelitia ini adalah kue tradisional Ombus-Ombus yang dapat di temukan pada acara-acara adat,serta di pasar tradisional yang ada di sumatera utara khususnya di Tapanuli Utara. Adapun tujuan penelitian ini yaitu untuk mengeksplorasikan etnomatematika pada kue tradisional khas batak. Penelitian ini merupakan penelitian kualitatif dengan pendekatan etnografi. Hasil penelitian ini akan menunjukkan terdapat unsur-unsur etnomatematika pada kue tradisional Ombus-ombus yang memiliki konsep serta nilai-nilai matematika di dalamnya.Teknik yang digunakan dalam pengumpulan data yaitu melalui observasi,dan dokumentasi.yang unik dari penelitian ini adalah masyarakat khas batak siborong-borong belum mengetahui bahwa Ombus-Ombus berkaitan di dalam ilmu Matematika bangun ruang yang berbentuk limas.Kata Kunci: Eksplorasi, Etnomatika, Kue Tradisional

Abstract

Algebra is important to learn as a provision in the face of future life, both at work and as preparation for higher education. However, basically students still have difficulty in solving algebra problems. Therefore, it is necessary to find out the factors that cause students' low algebraic abilities.The purpose of this study is to find the relationship between the algebraic abilities of students at Senior High School with their self-efficacy. The research is qualitative and quantitative. Statistic descriptive is to determine the connection and contribution of two variables, students' self-efficacy, and algebraic abilities. The research subjects taken were 200 students from Bukittinggi (West Sumatra). In this study, there were two instruments used, namely a self-efficacy questionnaire and an algebra test (SPLTV linear programming). The result shows that (1) In general, students' algebraic abilities are at a medium level with an average of 53.87. (2) Between algebraic abilities and self-efficacy have a very weak or very low correlation, so the correlation is ignored (it is assumed that there is no correlation between students' algebraic skills and self-efficacy) (3) Almost all students have good self-efficacy which is at a very high and quite low level. The finding implies that it is necessary to conduct research on the discovery of other factors that affect students' algebraic abilities.Aljabar penting dipelajari sebagai bekal dalam menghadapi kehidupan masa depan, baik di tempat kerja maupun sebagai persiapan menuju pendidikan tinggi. Namun, pada dasarnya siswa masih kesulitan dalam menyelesaikan soal aljabar. Oleh karena itu, perlu di cari tahu faktor penyebab kemampuan aljabar siswa yang masih rendah. Tujuan dari penelitian ini adalah untuk mengetahui hubungan antara kemampuan aljabar siswa SMA Negeri Bukittinggi dengan efikasi diri siswa. Penelitian ini merupakan gabungan antara kualitatif dan kuantitatif.  Deskriptif statistik untuk mengetahui hubungan dan kontribusi dua variabel yaitu efikasi diri dan kemampuan aljabar siswa. Subjek penelitian yang diambil adalah 200 siswa dari Bukittinggi (Sumatera Barat). Dalam penelitian ini terdapat dua instrumen yang menggunakan angket efikasi diri dan tes aljabar (SPLTV Program linear). Hasil penelitian menunjukkan bahwa (1) Secara umum kemampuan aljabar siswa berada pada taraf sedang dengan rata-rata 66,125. (2) Antara kemampuan aljabar dan efikasi diri memiliki korelasi yang sangat lemah atau sangat rendah, sehingga korelasi tersebut diabaikan (diasumsikan tidak ada hubungan antara kemampuan aljabar siswa dengan efikasi diri) (3) Hampir semua siswa memiliki efikasi diri yang baik berada pada tingkat yang sangat tinggi dan cukup rendah. Penelitian ini menunjukkan bahwa perlu dilakukan penelitian lebih lanjut tentang faktor lain yang mempengaruhi kemampuan aljabar siswa.

Abstract

Students' mathematical representation ability remains one of the fundamental competencies that is often underdeveloped in mathematics learning, particularly in topics requiring abstract reasoning such as trigonometric functions. Although the Flipped Classroom approach has been widely implemented, empirical evidence regarding its effectiveness in improving mathematical representation ability in Indonesian secondary education is still limited. This study aimed to examine the effectiveness of a Flipped Classroom strategy in enhancing students' mathematical representation ability. A quasi-experimental design with a pretest–posttest control group was employed involving 65 eleventh-grade students from a public senior high school in Indonesia, consisting of 32 students in the experimental group and 33 students in the control group. The experimental group received instruction through the Flipped Classroom strategy, whereas the control group was taught using conventional instruction. Data were collected using a mathematical representation ability test and analyzed through descriptive statistics, normality and homogeneity tests, and an independent samples t-test. The findings revealed that both groups had comparable initial abilities; however, the experimental group achieved a significantly higher posttest mean score (81.75) than the control group (70.24). Statistical analysis confirmed a significant difference between the two groups (t = 12.67, p < .001), indicating that the Flipped Classroom strategy effectively improved students' mathematical representation ability. These findings contribute to the growing evidence supporting student-centered, technology-enhanced learning environments for mathematics education and suggest that the Flipped Classroom can be adopted as an effective instructional strategy to foster mathematical representation skills in secondary schools.
