Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran Contextual Teaching and Learning berbantuan aplikasi Telegram terhadap kemampuan berpikir kreatif matematis siswa, serta mengidentifikasi kendala yang dialami siswa dalam proses pembelajaran tersebut. Penelitian ini menggunakan pendekatan kuantitatif dengan desain eksperimen semu One Group Pretest–Posttest. Subjek penelitian adalah 30 siswa kelas X-10 SMA Negeri 4 Tebing Tinggi. Instrumen yang digunakan meliputi tes uraian kemampuan berpikir kreatif matematis dan angket tertutup mengenai kendala penggunaan Telegram. Analisis data dilakukan melalui uji normalitas, uji-t berpasangan, dan perhitungan effect size. Hasil penelitian menunjukkan adanya pengaruh positif dan signifikan dari model Contextual Teaching and Learning berbantuan Telegram terhadap kemampuan berpikir kreatif siswa. Rata-rata skor meningkat sebesar 9,83 poin, dengan nilai t-hitung sebesar 12,099 dan effect size sebesar 2,21 yang termasuk kategori tinggi. Berdasarkan kategori kemampuan awal, peningkatan signifikan terjadi pada kelompok kemampuan rendah dan tinggi, sedangkan kelompok sedang juga mengalami peningkatan, meskipun tidak sebesar dua kelompok lainnya. Namun, hasil angket menunjukkan kendala yang dialami siswa, seperti terganggu oleh notifikasi luar (66,67%). Oleh karena itu, model Contextual Teaching and Learning berbantuan Telegram efektif dalam meningkatkan kemampuan berpikir kreatif, namun perlu strategi untuk mengatasi kendala penggunaan media digital dalam pembelajaran.

Abstract

Mathematical communication, which involves the ability to express and understand mathematical ideas, is very important in learning. However, many conventional learning methods are less effective in improving these abilities. This study combines gamification-based flash card innovation with the TAPPS model to maximize social and cognitive interactions in mathematics learning, which is expected to have a positive impact on student engagement and understanding. This study aims to explore the application of gamification-based flash cards with the Think Aloud Pair Problem Solving (TAPPS) model to improve junior high school students' mathematical communication skills. The research method used is classroom action research with several cycles that include (Planning, implementation, observation and reflection). Based on the research that has been conducted in 2 cycles with the application of the TAPPS model assisted by gamification-based flash cards, with an average of 84.8% in the first cycle and 94.1% in the second cycle. So there is an increase in students' mathematical communication skills. Therefore, gamification-based flash cards can be used as a medium to improve students' mathematical communication.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui adanya pengaruh yang tercipta dari dimensi kualitas terhadap keputusan pembelian ulang konsumen kopi di Kopi Kenangan Ruko Sultan Binjai. Metode yang digunakan dalam penelitian ini adalah metode kuantitatif dengan pendekatan deskriptif. Teknik pengumpulan data menggunakan angket dan wawancara. Adapun jumlah sampel pada penelitian ini menggunakan data langsung yang diperoleh melalui barista Kopi Kenangan sebanyak 120 responden yang merupakan customer tetap Kopi Kenangan. Teknik analisis data pada penelitian ini menggunakan analisis regresi berganda dan uji asumsi klasik yang meliputi uji validitas, uji reliabilitas, uji normalitas, uji multikolonieritas, uji hipotesis secara parsial dan uji koefesien determinasi. Hasil penelitian menunjukkan bahwa presentase pengaruh ketiga variabel (Cita Rasa, Higienis, dan Estetika Penyajian) dalam menaikkan Repuchase Intention sebesar 72,1% sedangkan 27,9 % dijelaskan oleh faktor lain yang berada diluar model dan tidak dapat terdeteksi dalam penelitian ini. Ketiga dimensi tersebut memberikan respon positif konsumen terhadap pembelian ulang (repuchase intention) menu minuman kopi di Kopi Kenangan Ruko Sultan Binjai, lalu merekomendasikan produk kepada orang lain.

Abstract

This study aimed to determine the improvement of students' mathematical communication skills in relation and function materials through the Reciprocal Teaching learning model in class VIII of SMPS National Development Pangkalan Susu. The researchers used classroom action research (CAR) which is carried out in 2 cycles, each cycle was carried out in 2 meetings. The subjects in this study were students of class VIII of SMPS National Development Pangkalan Susu, totaling 22 people. Data collection techniques used were teacher and student observation sheets, and tests of mathematical communication skills. The test was carried out 3 times, namely a diagnostic test, a test for mathematical communication skills I, and a test for mathematical communication skills II. The results of the research at the time of the diagnostic test showed that the students' mathematical communication skills in explaining/writing the elements were known, the elements were asked and concluded correctly and completely (33.4%), painting pictures, diagrams, graphs, or tables completely and correctly (38%), and express mathematical ideas using symbols or mathematical language in writing as a complete and correct representation of an idea or ideas (32%). After being given action in Cycle I and Cycle II, the students were able to explain/write known elements, ask questions and conclusions correctly and completely, describe pictures, diagrams, graphs, or tables completely and correctly, and state mathematical ideas using symbols or mathematical language in writing as a complete and correct representation of an idea or idea. The results of the mathematical communication ability test given in the classical cycle I obtained that students who completed were 10 students (45.45%) out of 22 students with an average of 58.09, in the second cycle who completed increased to 16 students from 22 students (81 ,81%) with an average of 74.18 and has achieved the classical completeness criteria because 80% of the number of students have mathematical communication skills in the sufficient category, namely 70. Based on the results of the study, it can be concluded that the Reciprocal Teaching model can improve students' mathematical communication skills in SMPS National Development of Pangkalan Susu.
