Abstract

Indonesian students' mathematical literacy based on PISA and PIRLS assessments is still in the low category. Mathematical literacy covers how students are able to know and use basic mathematics to solve problems in real life contexts. Problem Based Learning Model is a learning model that can solve problems in real life contexts by facilitating the development of junior high school students' mathematical literacy. The main principle of Problem Based Learning emphasizes mathematical problems that are human activities and must be meaningful for students, become a motivator to improve mathematical literacy skills through the stages of learning. This article examines the mathematical literacy ability of SMP Negeri 11 Bengkulu students before and after going through the Problem Based Learning Model. Students' mathematical literacy skills prior to the application of the Problem Based Learning model have a percentage of 25% for the medium category and 75% are in the low category. Then for students' mathematical literacy ability after applying the Problem Based Learning model has a percentage of 5% for the medium category, 90% is in the low category, and 5% is in the high category. The results of inferential statistical analysis (Paired Sample T-test) obtained a significance value <0.05. This means that there is an increase in students' mathematical literacy skills after the application of the Problem Based Learning model in class VII SMP Negeri 11 Bengkulu City.Keywords: Literacy Ability, Problem Based Learning

Abstract

This study was aimed to know the differences in students' mathematical problem solving skills in problem basedlearning models with cooperative type thinking aloud pairs problem solving with a scientific approach at SMA Negeri 7 Bengkulu. Thedesign of this research was a quasi-experimental, used a pre-test post-test control group design. The population in this study were all students of class X MIPA SMA Negeri 7 Bengkulu consist of 6 classes, with samples consist of 3 classes, the first experimental class with the problem based learning model, the second experimental class cooperative learning model type thinking aloud pairs problem solving and conventional learning as a control class. The sampling technique used simple random sampling. Data collection was done by using a test of students' mathematical problem solving skills. The results of the research data were analyzed using one-way ANAVA test and BNT test. The prerequisite test used the Kolmogrove-Smirnov test to see normality and Bartlet's test to see homogeneity. The significant level used is 0.05. The research data showed  that there was a significant difference in students' mathematical problem-solving ability in the learning model of Problem Based Learning, cooperative type thinking aloud pairs problem solving in SMA Negeri 7 Bengkulu, and problem based learning learning model which gives better results compared to the thinking type cooperative learning model thinking aloud Pairs problem solving at SMA Negeri 7 Bengkulu.Keywords: mathematical problem solving, PBL,TAPPS

Abstract

This study aimed to see differences in the ability of understanding the mathematical concepts that students taught through cooperative learning model jigsaw with conventional learning on eighth grade students of SMPN 18 Bengkulu academic year 2013/2014. This research is a quasi experimental study. The study population is the entire eighth grade students of SMP Negeri 18 Bengkulu city. The research sample determined by random sampling technique and obtained  VIII.2 classes to taling 30 students as classroom control, and VIII.3 graders who totaled 30 students as a class experiment. The data collected is the data from the pre-test and post-test students' comprehension of  mathematical concepts, the data were analyzed using t-test. The results of this study indicate that while t table t count=2.1652785=2.00172 which means that there are differences in the ability of students' understanding of concepts taught through cooperative learning model jigsaw with conventional learning on eighth grade students of SMPN 18 Bengkulu academic year 2013/2014. Based on the results of this study concluded that the Jigsaw cooperative learning model affect the ability of students 'understanding of the concept compared to conventional learning, so that there are differences inthe ability ofstudents'understanding of mathematical concepts of these two classes.Keywords: ability of understanding the mathematical concepts, Jigsaw cooperative learning model

Abstract

Tujuan penelitian ini untuk menghasilkan soal-soal kemampuan penalaran matematis materi bangun ruang sisi datar berkonteks Bengkulu yang terstandar: yang valid, memiliki keterbacaan baik,  memiliki tingkat kesukaran dan indeks daya beda baik. Penelitian ini yang dilaksanakan pada tahun ajaran 2020/2021 ini mengikuti alur  Tessmer. Subjek ujicoba adalah siswa kelas VIII SMP di Bengkulu. Sebelum prototipe soal dibuat, dilakukan analisis siswa, kurikulum, materi dan konteks. Telaah dan revisi soal dilakukan pada tahap experts review. Soal ditelaah oleh 3 orang validator dari sisi konten, konstruk, dan bahasa. Komentar dan saran validator pada proses validasi menjadi acuan untuk revisi soal. Hasil analisis validasi akhir para validator menunjukkan bahwa soal telah valid. Proses one to one pada 3 orang siswa kelas VIII yang  masing-masing berkemampuan tinggi, sedang, dan rendah, Tergambar dari proses one to one bahwa maksud soal dapat terbaca oleh siswa. Bukti empirik mengenai tingkat kesukaran dan indeks daya beda butir soal diperoleh pada tahap small group, dengan cara mengujicobakan soal yang telah valid dan memiliki keterbacaan yang baik kepada 31 siswa kelas VIII SMP di Bengkulu.  Skor siswa terhadap soal tersebut dianalisis secara kuantitatif. Hasil analisis menunjukkan bahwa 8 soal dikembangkan dikategorikan terstandar. Soal-soal ini dapat digunakan untuk melatih kemampuan penalaran matematis siswa SMP. Kata Kunci: Soal matematika, kemampuan penalaran matematis, konteks Bengkulu, bangun ruang sisi datar  Abstract The purpose of this research was to produce standardized items on mathematical reasoning abilities in the Bengkulu context of flat-sided geometry: those that were valid, had good clarity appeal, had a difficulty level and a good discrimination index. This research, which was conducted in the 2020/2021 academic year, follows the Tessmer’ model. The test subjects were students of class VIII SMP in Bengkulu. Before the items prototype was made, an analysis of students, curriculum, material and context was carried out. The review and revision of the items were carried out at the experts review stage. The items were reviewed by 3 validators in terms of content, construct, and language. The validator's comments and suggestions in the validation process become a reference for revision of the questions. The results of the final validation analysis of the validators, showed that the questions were valid. One to one process for 3 students of class VIII, each of which has high, medium, and low abilities. It is illustrated from the one to one process that the meaning of the questions can be read by students. Empirical evidence regarding the level of difficulty and discrimination index of items was obtained at the small group stage, by testing items that were valid and had good readability to 31 grade VIII SMP students in Bengkulu. Student scores on these items were analyzed quantitatively. The results of the analysis showed that the 8 items developed were categorized as standardized. These items can be used to exercise the mathematical reasoning skills of junior high school students. Keywords: Item test of mathematics, mathematical reasoning ability, Bengkulu context, flat-sided geometry
