Abstract

The purpose of this study was to improve student learning outcomes using the Poster Session strategy. Based on observations made by researchers in class VIII before the study, it was found that the lack of activity of students and many students who had not achieved learning outcomes according to the minimal completeness criteria was 60. The reason is that students are not actively involved by the teacher in learning process. Efforts to solve this learning problem the author uses the Poster Session strategy. The level of success is viewed from 3 aspects, namely student learning completeness which is examined from the results of the cycle I and II tests, observation of teacher activities and student activities. Based on the results of the analysis after the implementation of the study, the researchers found that all student learning completeness in the first cycle was 48% and in the second cycle was 95% so there was an increase in student learning outcomes by 47%. Observers' observations on the activities of students in learning cycle I were 57% and in cycle II 90% so there was an increase of 33%. Observer observation results on the first cycle teacher activities were obtained at 52.62% and in the second cycle it was 94.78% so that an increase of 42.16%

Abstract

This descriptive theoretical study aims to explain in detail and complete aspects of mathematical communication in mathematical literacy. Communication in mathematical literacy has two important components, namely receptive and constructive. In each process of solving a problem, the two components of communication will always be contained. Professional teachers must properly understand the two components in order to measure students' mathematical communication skills correctly. To be easy to understand, the two components must be conveyed or stated correctly, coherently, and clearly. Emphasis on these three components then distinguishes mathematical communication from other mathematical abilities, such as problem solving, reasoning and proof, connection and representation

Abstract

This study aimed at knowing the effect of the STAD type Cooperative learning model assisted by GeoGebra on mathematics learning outcomes in terms of students' initial knowledge. This research used quasi-experimental study with a 2x2 research design. The population of this study was all first semester students of the Informatics Engineering Department of STIKI INDONESIA. Sampling was done by cluster random sampling technique where the sample obtained was 72 students. The prior knowledge data was collected through prior knowledge tests and mathematical learning outcome data collected through tests of mathematics learning outcomes in the cognitive domain. The data obtained were analyzed using analysis of variance (ANOVA) two lanes with the help of the SPSS 20.0 for Windows program at a significance level of 5%. The results showed that (1) the learning outcomes of students who were taught by the GeoGebra-assisted STAD type cooperative learning model were better than student learning outcomes taught with conventional learning models, (2) there was no interaction between the GeoGebra-assisted STAD type learning model and prior knowledge towards the results of student mathematics learning. Student mathematics learning outcomes both in students who had high prior knowledge and low prior knowledge were always better if they were taught by GeoGebra assisted STAD type cooperative learning model.

Abstract

This study aims to compare the mathematical problem solving abilities of students who use problem solving learning models with direct learning models in the linear program material of the first grade students at SMK Informatika St. Petrus Ruteng in academic year 2018/2019. This research is an experimental research using the design of Posttest-Only Control Design. The population of this research is all students of class X SMK Informatics St. Petrus Ruteng which amounted to 213 people divided into 6 classes with details of the first TKJ 36 people, TKJ II 36 people, TKJ II 36 people, TKJ IV 35 people, TKJ V 35 people and TKJ VI 35 people. Sampling is done by random class. The number of members of the study sample was 71 people. Data on problem solving abilities were collected by a description test. Data were analyzed using t-test calculations with the polled formula variant. Based on the results of data analysis, it was found that the results of t_count = 3.132 and t_table = 1.995 at significant level α = 5% and degrees of freedom = 69. Because t_count> t_table then H_0 is rejected and H_1 is accepted, which means that mathematical problem solving abilities of students using models Problem Solving learning is better than students' mathematical problem solving abilities using direct learning models in linear program material.

Abstract

Kemampuan koneksi matematis merupakan kemampuan untuk mencari hubungan inter topik, antar topik, suatu topik dengan ilmu lain, atau suatu topik dengan masalah dalam kehidupan sehari-hari dalam bidang matematika. Kemampuan koneksi merupakan salah satu aspek yang harus dimiliki siswa agar berprestasi dalam belajar matematika. Penelitian ini merupakan penelitian kualitatif yang bertujuan mendeskripsikan profil kemampuan koneksi matematis siswa sekolah menengah atas (SMA) pada masalah fungsi komposisi. Penelitian ini melibatkan 36 orang siswa sekolah menengah atas dan dipilih 3 orang siswa sebagai subjek utama. Data kemampuan koneksi matematis dikumpulkan melalui tes, tugas, dan wawancara tidak terstruktur sesuai dengan tugas yang diberikan. Data dianalisis secara kualitatif untuk memahami, menelaah, dan menafsirkan koneksi matematis siswa sekolah menengah atas pada masalah fungsi komposisi. Hasil penelitian menunjukkan bahwa (1) siswa sekolah menengah atas dengan tingkat disposisi matematis tinggi memiliki kemampuan koneksi matematis yang baik. Siswa tersebut mampu melakukan koneksi baik inter topik maupun antar topik. Selain itu juga, mampu melakukan koneksi materi matematika dengan bidang lain maupun materi matematika dengan kehidupan sehari-hari, (2) siswa sekolah menengah atas dengan tingkat disposisi matematis sedang memiliki kemampuan koneksi matematis yang cukup baik. Siswa tersebut mampu melakukan koneksi baik inter maupun antar topik dalam matematika. Namun, belum dapat melakukan koneksi matematika dengan bidang lain atau koneksi materi matematika dengan kehidupan sehari-hari, dan (3) siswa sekolah menengah atas dengan tingkat disposisi matematis rendah memiliki kemampuan koneksi matematis yang kurang baik. Siswa SMA dengan tingkat disposisi matematis yang rendah mampu melakukan koneksi inter topik dalam materi matematika. Namun, siswa tersebut masih sangat kesulitan dalam melakukan koneksi antar topik dalam matematika, dan juga kesulitan dalam melakukan koneksi materi matematika baik dengan bidang lain maupun dengan fenomena dalam kehidupan sehari-hari. Hasil penelitian ini memberikan kontribusi berupa masukan dan rekomendasi bagi guru matematika dan penentu kebijakan di sekolah menengah atas agar membimbing dan meningkatkan kemampuan koneksi matematis siswa sesuai dengan tingkat disposisi matematis.
