Abstract

Lima standar kemampuan matematis yang harus dimiliki siswa salah satunya adalah kemampuan pemecahan masalah. Salah satu pendukung peningkatan kemampuan pemecahan masalah adalah adanya self-efficacy pada diri siswa. Penerapan model pembelajaran ARIAS berpendekatan saintifik diharapkan efektif terhadap kemampuan pemecahan masalah. Tujuan penelitian ini untuk mengetahui keefektifan model pembelajaran ARIAS berpendekatan saintifik yang telah ditetapkan dan menganalisis kemampuan pemecahan masalah ditinjau dari self-efficacy siswa dalam model pembelajaran ARIAS dengan pendekatan saintifik. Penelitian ini merupakan penelitian kombinasi (mixed methods) dengan tipe strategi konkuren embedded. Populasi dalam penelitian ini adalah siswa kelas VIII SMP Negeri 15 Semarang dengan subjek penelitian diambil dari kelas eksperimen yang terdiri dari enam orang, yaitu masing-masing ada dua subjek dengan self-efficacy tinggi, sedang, dan rendah. Hasil penelitian menunjukkan bahwa model pembelajaran ARIAS berpendekatan saintifik efektif terhadap kemampuan pemecahan masalah berdasarkan uji keefektifan yaitu uji ketuntasan rata-rata dengan , uji proporsi dengan zhitung = 2,61 > ztabel = 1,65, uji perbedaan  rata-rata dengan thitung = 2,309 > ttabel = 1,67, dan uji beda proporsi dengan zhitung = 1,87 > ztabel = 1,65. Selain itu, siswa dengan self-efficacy tinggi sudah mampu mencapai keempat aspek dari kemampuan pemecahan masalah, sedangkan self-efficacy sedang dan rendah belum mencapai secara maksimal keempat aspek dari kemampuan pemecahan masalah One of my five standards of mathematical ability that must be owned is solving ability. One of the supporters to increase Problem-Solving Ability is self-efficacy in students. The application of ARIAS approach model of scientific approach is expected to solve the problem that happened. This study aims to determine the effectiveness of ARIAS model of with scientific approach that has been established and analyze the problem-solving abilities in terms of student self-efficacy in the ARIAS learning model with scientific approach. This research is a combination research (mixed methods) with embedded concurrent strategy type. The population in this study is the students of class VIII SMP Negeri 15 Semarang with research subjects taken from the experimental class consisting of six people, each of which there are two subjects with high, medium, and low self-efficacy. The results show that ARIAS Learning model with scientific approach is effective to improve problem solving ability based on the effectiveness test that is the average mastery test with , the proportion test with zhitung = 2,61 > ztabel = 1,65, test Average difference with thitung = 2,309 > ttabel = 1,67, and test the difference of proportion with zhitung = 1,87 > ztabel = 1,65. In addition, high self-efficacy students are able to achieve the four aspects of problem-solving ability, while moderate and low self-efficacy have not reached the maximum of four aspects of problem-solving abilities.

Abstract

The ability of students mathematical literacy (KLM) in MTs is still low because problems related to daily life are not used as the source of concept formation. The purpose of this study was to find out whether the Realistic Mathematic Education (RME) learning with character of Islam effectively improves students KLM and analyzed. Type of research used mixed methods with concurrent embedded research design with two types of data. Quantitative data are the value KLM in pretest and posttest which is analysed by ttest, gaintest and qualitative through three procedures namely reduction, presentation and conclusion. The two classroom research subjects are experiment and expository. The result of this research experiment is effective, because (1) experiment KLM has reached classical completeness exceeding 75%; (2) improvement of student KLM on experiment higher than student expository. The ability of students mathematical literacy on the category is very good, good and good enough.

Abstract

This research was aimed (1) to know the effectiveness of MiC learning with recitation and peer assessment based on Semarang Culture to students’ mathematical connection ability and (2) to analyze students’ mathematical connection ability and self regulated learning. This study was a mixed method research with a sequential explanatory design. The population was 7th grade students of SMP N 32 Semarang academic year 2017/2018. The subjects was selected based on the students’ initial matehamtical ability which is categorized as upper, middle and lower group students. Data was collecting by questionnaire, observation, test, and interview. The result showed that (1) MiC learning with recitation and peer assessment based on Semarang Culture is effective on students’ mathematical connection ability, (2) students in the upper group category can connect between topics in mathematics, connect mathematical concepts with other diciplines, connect mathematics with daily life well and have a high level of self regulated learning, students in the middle group category can connect mathematical concepts with other diciplines and connect mathematics with daily life well and have a moderate level of self regulated learning, and for students in lower group category can connect mathematical concepts to other diciplines well and have a low level of self regulated learning.

Abstract

Mathematical communication ability is a term for solving problems, and self-esteem is a factor that determine student’s success to get achievements. A good mathematical communication ability and self-esteem can help students to solve a problem. The aim of this research are (1) to know the quality of MiC learning process with nuance of Jepara culture to improve student’s mathematical communication ability, and (2) to know the student’s mathematical communication ability reviewed from self-esteem on MiC  learning process with nuance of Jepara culture. The type of this research is mixed methods model concurrent embedded. The population of this research is the students of grade X MIA Pecangaan Senior High School, Jepara. The subject of this research determined based on the low and high self-esteem category. Data collection technique are questionnaire, observation, test, and interview. The result of this research showed that (1) MiC learning process with nuance of Jepara culture has a high quality both qualitative and quantitative, (2) mathematical communication ability on students with low self-esteem can describe mathematic ideas in visual form well. Beside, mathematical communication ability on students with high self-esteem can describe mathematic ideas in visual form well, can state the daily events to language or mathematic symbols, can understand and evaluate the mathematic ideas on solving problems in writing, and they also can communicate the conclusion of an answer problem suitable with the question.
