Abstract

This study aims to determine the effectiveness of the application of the GeoGebra-assisteddiscovery learning model to learning outcomes in mathematics for grade VIII junior high school studentswith indicators of learning effectiveness, namely student learning outcomes, student activities, andstudent responses. This study is a pre-experiment with a quantitative approach to a one group pretest-posttest design using cluster random sampling techniques. The population in this study was students inclass VIII junior high school, and the research sample consisted of one experimental class group of 23students. Pretests and posttests were used to collect data on student learning outcomes; student activityobservation sheets were used to collect data on student activity; and student response questionnaireswere used to collect data on student response. The data were analyzed using descriptive statistics andinferential statistics so that, in general, it can be concluded that the application of the GeoGebra-assisteddiscovery learning model is effectively applied to mathematics learning for grade VIII junior high schoolstudents.

Abstract

This research was quasi-experimental which aims to know the difference between students' mathematics learning outcomes who are taught by using cooperative learning model TGT type and students' mathematics learning outcomes who are taught by using cooperative learning model NHT type viewed from students’ interpersonal intelligence. The population in this research was Ten-grade students. The sample consisted of two classes, namely class X MIA 1 as first treatment class taught by using TGT learning model and class X MIA 2 as second treatment class taught by using direct NHT learning model selected by cluster random sampling technique. The variables in this research were cooperative learning model, students’ interpersonal intelligence, and mathematics learning outcomes. The research instruments used were observation sheets, questionnaires about students’ interpersonal intelligence, and mathematics learning outcomes tests. The data obtained were analyzed by using descriptive analysis and inferential analysis through Two Way ANOVA. Based on the result of the Two Way ANOVA, it was found that there is no difference between students' mathematics learning outcomes who are taught by using cooperative learning model TGT type and students' mathematics learning outcomes who are taught by using cooperative learning model NHT type viewed from students’ interpersonal intelligence.

Abstract

This research was conducted to determine the comparison of student learning achievement through the application of the cooperative model type Snowball Throwing and Make a Match in mathematics learning. This research was an experimental research involving two groups treated with research sample of 47 students from class VII SMP Sinjai selected by using the double cluster random sampling technique. Techniques of collecting data using instruments: (1) observation sheet of learning model implementation and (2) tests of mathematics learning result.Data were analyzed with descriptive statistics and inferential statistics with t-test analysis. The results showed that : (1) Average score of mathematics learning achievement of 25 students after learning using the Snowball Throwing type of cooperative learning model which is 4% in the very low category, 40% in the medium category, 36% in the high category and 20% in the very high category. (2) The average score of mathematics learning achievement from 22 students after learning using the Make a Match type of learning model is 9.09% in the very low category, 4.54% in the low category, 50% in the medium category and 18, 18% in the high and very high categories. (3) There is no significant difference between student achievement after applying the snowball throwing type cooperative learning model and the type of make a match in Class VII Junior High School with the Rectangular Build Up material.

Abstract

This research aims to describe students' thinking processes in solving trigonometry problems in terms of reflective and impulsive cognitive styles. It is a descriptive study with a quantitative and qualitative approach. The subjects in this research were four students from the 11th grade of a high school, two students in each group representing the reflective and impulsive cognitive styles based on their results in the trigonometry problem-solving test. Data were collected through tests and interviews. The instruments used for data collection included trigonometry problem-solving tests, MFFT cognitive style tests, and interview guidelines. The results of this research indicate that: (1) Students with a reflective cognitive style and high scores in the trigonometry problem-solving test (SRT)tend to undergo an assimilation process, reaching equilibrium at each stage of problem-solving. (2) Students with an impulsive cognitive style and high scores in the trigonometry problem-solving test (SIT) also experience an assimilation process, reaching equilibrium, but undergo accommodation during the stage of planning problem-solving strategies. (3) Students with both reflective and impulsive cognitive styles and low scores in the trigonometry problem-solving test (SRR and SIR) tend to be in a state of disequilibrium, unable to integrate the existing schemes in their minds with their knowledge.

Abstract

This study aims to know the description of students' error in solving Higher Order Thinking Skills (HOTS) mathematical problems and the description of errors differences of geometry based on Hadar criteria. This type of research is descriptive research using qualitative approach. Retrieval of the subject is performed by providing prior knowledge test of grade XII MIPA 3 , then from the result of thetest selected 6 subjects based on existing categories. The instrument used in this research are prior knowledge test which contains 30 number of multiple choices, written tests of Higher Order Thinking Skills which contains 2 number of essay and interview guidelines. Errors are analyzed by using the Hadar error category which consists of 6 errors. The results of this research show that based on the Hadar error criteria, errors that occur are misused data, misinterpreted language, logically in valid inference, distorted theorem or definition, unverified solution, and technical error. Subjects who solving HOTS mathematics problem of geometry tend to make logically invalid inference, distorted definition or theorem, and technical errors. The results of this research are expected to add insight about the types of errors made by the students of senior high school in geometry topic, especially in solving higher order thinking skills problems so that the mistakes can be immediately minimized in the process of learning.

Abstract

Penelitian ini bertujuan untuk mengurangi kesalahan siswa dalam operasi perkalian dengan menerapkan metode perkalian latis. Jenis penelitian ini adalah penelitian kualitatif dengan metode Penelitian Tindakan Kelas (PTK). Subjek penelitian adalah 24 siswa yang dipilih secara purposive. Penelitian dilaksanakan di kelas VII dari salah satu SMP di Parepare. Tahun ajaran 2018/2019. Intrumen penelitian yang digunakan terdiri atas lembar observasi, soal tes, dan angket. Desain PTK menggunakan model Kemmis dan Tanggart yang meliputi perencanaan, tindakan/pelaksanaan, observasi, dan refleksi. Hasil penelitian menunjukkan bahwa Skor rata-rata hasil tes matematika siswa setelah pemberian tindakan pada siklus I adalah 58,33 dari skor ideal 100 dan sebanyak 15 siswa yang melakukan kesalahan dalam operasi perkalian. Sedangkan skor rata-rata hasil tes matematika siswa setelah pemberian tindakan pada siklus II adalah 80,83 dari skor ideal 100 dan sudah tidak ada lagi siswa yang melakukan kesalahan. Kesalahan siswa dalam menyelesaikan soal operasi perkalian bilangan bulat dan bilangan pecahan desimal terdapat tiga aspek kesalahan yaitu kesalahan dalam memahami konsep, kesalahan proses penyelesaian, dan kesalahan penarikan kesimpulan. Sehingga dapat disimpulkan bahwa penerapan metode latis dapat mengurangi kesalahan siswa dalam operasi perkalian ditinjau dari kemampuan awal siswa SMP di Parepare
