Abstract

AbstrakTujuan penelitian ini adalah untuk mengetahui keefektifan pembelajaran matematika dengan pendekatan Polya Questioning Instruction (PQI) untuk meningkatkan kemampuan penalaran geometris siswa kelas VIII SMP Negeri 5 Yogyakarta. Pembelajaran matematika dengan pendekatan PQI ini menggunakan model problem solving dengan strategi pemberian pertanyaan (questioning). Pertanyaan-pertanyaan yang diberikan bertujuan untuk mengarahkan siswa berpikir dan bernalar untuk menyelesaikan masalah sesuai dengan langkah pemecahan masalah Polya yaitu (1) memahami masalah (understanding the problem), (2) merencanakan cara penyelesaian (devising a plan), (3) melaksanakan rencana (carrying out the plan), dan (4) melakukan pengecekan kembali terhadap semua langkah yang telah dikerjakan (looking back).Desain penelitian untuk memperoleh data mengenai kemampuan penalaran geometris siswa menggunakan bentuk pra-experimental design yang digunakan adalah One-Shot Case Study dimana suatu kelompok diberi perlakuan kemudian diukur hasilnya. Populasi dalam penelitian ini adalah siswa kelas VIII SMP Negeri 5 Yogyakarta. Sampel penelitian adalah 32 orang siswa kelas VIII.7 SMP Negeri 5 Yogyakarta yang telah memiliki kemampuan awal yang cukup untuk mempelajari konsep.Instrumen yang digunakan pada penelitian ini adalah soal tes kemampuan penalaran geometris. Pendekatan PQI efektif apabila persentase siswa yang memenuhi ketuntasan secara klasikal pada tes kemampuan penalaran geometris minimal mencapai 75%, dan proporsi siswa yang telah mencapai skor kemampuan penalaran geometris minimal kategori tinggi mencapai lebih dari atau sama dengan 75%. Hasil tes kemampuan penalaran geometris siswa menunjukkan bahwa pendekatan PQI efektif untuk meningkatkan penalaran geometris siswa. Hal ini dikarenakan persentase siswa yang mencapai KKM pada tes kemampuan penalaran geometris adalah 75%. Berdasarkan uji hipotesis dengan taraf signifikansi 5%, diperoleh kesimpulan bahwa proporsi siswa mencapai kategori minimal tinggi lebih dari atau sama dengan 75%. Kata kunci: Polya Questioning Instruction, Questioning, Penalaran Geometris

PTK dilaksanakan dalam 3 siklus yang mana setiap siklusnya terdiri atas tahapan perencanaan, tindakan/observasi, dan refleksi. Instrumen yang digunakan adalah instrument tes formatif yang bertujuan untuk mengukur kemampuan pemahaman konsep matematika pada pokok bahasan logaritma. Tes formatif diberikan pada setiap akhir siklus. Berdasarkan analisis data secara deskriptif kuantitatif diperoleh hasil penelitian berupa peningkatan hasil belajar matematika siswa pada setiap siklusnya. Hasil akhir penelitian menunjukkan bahwa penerapan strategi pembelajaran aktif learning tournament dapat meningkatkan hasil belajar siswa dengan persentase pada siklus I sebesar 67,50 % , siklus II sebesar 75,00 % dan siklus III sebesar 80,00 %.

Abstract

One method of predicting stock prices is to use the time series analysis method. In this method, a linear prediction model is made to see patterns from historical stock price data to assess future prices. The stock data used in this study is the daily stock data of PT. Telkom and PT. Indosat in 2020-2021. Autoregressive (AR) model is a time series model that is often used with the assumption that its volatility does not change with time (Homoscedastic). After analyzing the AR Model(1) data for the stock data of PT. Telkom and PT. Indosat has a non-independent error, therefore the AR(1)-N.GARCH(1,1) time series model construction was carried out to model the error (ϵ_(i,t)). Furthermore, the error of the AR(1)-N.GARCH(1,1) model is independent of t, so it can be modeled using Copula. After the Copula model was applied to the data and obtained the value of the fit of the Gaussian Copula distribution error model. From the values generated from the Gaussian Copula C({ϵ_(i,t) }_(t=1)^T ),T=1,2,…, and approximates a uniform distribution. So the stock data of PT. Telkom and PT. It can be said that Indosat is not suitable to be modeled with the Gaussian Copula.

Abstract

This research examined: (1) the effectiveness of learning through a goal-free problem strategy compared with learning through a goal-given problem strategy with regard to transfer ability, reasoning, or cognitive load; (2) the effectiveness of learning collaboratively compared with learning individually with regard to transfer ability, reasoning, or cognitive load; and (3) interaction between learning strategy (goal-free or goal-given) and setting (collaborative or Individual) in terms of transfer ability, reasoning, or cognitive load. The experiment was conducted using a 2 (setting: collaborative vs. Individual) x 2 (strategy: goal-free vs. goal-given) factorial design; posttest-only control-group. The results of the data analysis supported hypothesis that the students who learned by goal-free problems strategy led to be better in terms of near and far transfer scores than students who learned by the goal-given strategy. The goal-free problems strategy was also proved to be more effective in terms of students' reasoning in near and far transfer tests rather than the goal-given problems strategy. Collaborative learning more effectively minimizes cognitive load during acquisition and near transfer test phase than students learn individually, also effectively facilitating students in terms of the near transfer only than students in individual learning. There was a significant interaction effect between the learning setting factor and strategy factor in terms of near transfer ability and reasoning in the near transfer test. Simple effect test showed that learning collaboratively by goal-given strategy was significantly more effective in terms of near transfer ability and students’ reasoning in the near transfer test, and learning individually by goal-free strategy was significantly more effective in terms of near transfer ability and students’ reasoning in near transfer test.

Abstract

Self efficacy is a basic belief in learning, especially learning mathematics, because self efficacy can have a strong effect that can show students' self-confidence, when students have a high self-efficacy category, students can solve problems in learning mathematics well. This study aims to analyze the self efficacy of students in learning mathematics with the Search, Solve, Create, Share (SSCS) learning model. This research is a descriptive quantitative research. The subjects in the study were students of class VIII SMPN 8 Bukittinggi and a sample of 30 people. The instrument used is a self efficacy questionnaire. The data analysis technique uses descriptive statistical analysis using the percentage of degrees of achievement. The results of the study were obtained that the self efficacy of students with the learning model given search, solve, create share there were 8 students in the high category, 21 students in the high enough category, and 1 student in the medium category. While overall the degree of achievement of students' self efficacy is in the high enough category. Where for each dimension of students' self efficacy is also in the high enough category.

Abstract

This study investigates how effective rapid calculation training is in improving the basic math skills of Madrasah Ibtidaiyah (MI) teachers in West Sumatra. This research was conducted because teachers rarely use effective calculation strategies and there are no professional development programs specifically aimed at enhancing their basic math skills. A quantitative method was used with a single pretest-posttest group. The study involved 125 teachers from four Madrasah Ibtidaiyah located in West Sumatra, and 96 participants were selected using purposive sampling. Data were collected through rapid calculation tests administered before and after the training intervention. Paired-sample t-tests and the N-Gain index were used to analyze the collected data. The results showed a statistically significant improvement in participants' performance after the training, with a significance value of 0.000 (p < 0.05). In the posttest, the average score increased from 36.00 in the pretest to 67.27 in the posttest. In addition, the level of participant competence improvement is shown by an N-Gain value of 0.49. The results indicate that calculation training is effective in quickly improving the basic mathematics competence of MI teachers. These results also show that this type of training can serve as a feasible professional development program to enhance teachers' mathematics skills and improve the quality of mathematics learning in Madrasah Ibtidaiyah.
