Abstract

This study aims to analyze the understanding of the concept of the Fractions operations of Mappi students. This was qualitative research with the subject were 5 students from Mappi Regency, Papua in the Class A matriculation program. The study was conducted in February-May 2019. Data were obtained from written test results and were strengthened by interview results. Test results and interviews were analyzed descriptively and qualitatively. The results showed that the five students of Class A matriculation program had different concept understanding abilities. Subject 1 could understand the concepts of addition and subtraction in the fraction operation and changed the form of mixed fractions into ordinary fractions. Subject 2 could understand the concept of addition in fraction operations and change the form of mixed fractions into ordinary fractions. Subject 3 understands the concepts of addition and subtraction in fraction operations, which could represent and change the form of mixed fractions into ordinary fractions. Subject 4 could understand the concepts of addition and subtraction in the operation of fractions. Subject 5 had a low understanding of the concept and could only change the form of mixed fractions into ordinary fractions. With these results, the conceptual understanding of 5 Mappi students about fractional operations needs to be improved.

Abstract

Multiplying and dividing fractions often become a complicated problem for elementary school students. Students have difficulty doing fraction computation on, especially on dividing fractions. The same thing happens to students of class VB SDN Indrasari 2 Martapura, who has a problem solving multiplying and dividing fractions. The effort used to solve the problem is by using a tiered drilling method. It was done because the characteristic of students who needs a structured drill which started from a simple to a complex problem. The research aims to know the improvement of activity and ability to multiplying and dividing fraction of students’ class VB SDN Indrasari 2 Martapura by learning using tiered drilling. The research method was action research. The research subjects were 21 students of class VB SDN Indrasari 2 Martapura Data was collected by Observation and test and analyzed using averages and percentages. The research subjects were student’s activity and ability to solve multiplying and dividing fractions. The results show that there is an improvement of student’s activity from the middle to very active and student’s ability to solve multiplying and dividing fraction from high to very high.

Research utilizing Microsoft Excel software. Development of teaching materials through stages, preliminary study dan formative study. The preliminary stage included preparation and design, the formative study stage included Self Evaluation, Expert Reviews, One to One, Small Group and Field Test. The validity of teaching materials was stated by two experts (expert review), two peers and three students (one-to-one). The practicality of instructional materials was seen from the results of small group activities. Based on the result of field test, it was found that the use of LAM teaching materials based on the APOS theory developed had a potential effect on the comprehension ability of mathematics concept especially in Riemann sum concept, From the result of the test, the percentage of concept comprehension was above 61.00%. this illustrates all of indicators of understanding students' mathematical concepts were good.

Abstract

This descriptive qualitative research aims to describe the students' strategic competence with high and low mathematical anxiety in solving linear program problems. The subjects of this research were one student with low mathematical anxiety (S1) and one student with high mathematical anxiety (S2). The main instrument was the researchers supported by the test instrument and interview guidelines. Data from test and interview results were analyzed using steps data reduction, data display, and conclusion drawing. The results showed that both participants formulated problems by writing down the essential information and linking pieces of information with prior knowledge. Both participants represented problems by using words in formulating problems. S1 described problems using mathematical models, equations, graphs, and concepts in solving problems while represented problems using tables, mathematical models, equations, charts, and concepts in solving problems. Both participants resolved problems by planning a solution and implementing it. S1 determined and choose the correct answer of the problems while S2 had difficulty in modeling problems so that S2 modeled problems by guessing. S2 was wrong in modeling problems. Finally, the next work steps of S2 were also wrong, and S2 did not find the correct solution.

Abstract

This qualitative research aims to reveal in depth the intervention of mathematical anxiety in creative thinking when the subject explains the questions of proof in front of the class. The research subjects were two prospective mathematics teacher students, one was a student with a high level of mathematics anxiety (CT) while the other was a student with a low level of mathematics anxiety (CR), but both subjects had equal mathematical abilities. Data were analyzed qualitatively through five stages: data analysis, data validity checking, data reduction, data presentation, and drawing conclusions. The results of this study indicate that both subjects can produce unique (original) ways of solving problems, but CR is more smooth, detailed, and flexible in thinking. In addition, this study also found that CR is not careful in thinking so that she makes small mistakes that are not intentional.

Abstract

Tujuan pada penelitian ini untuk mengetahui kemampuan matematis dalam menyelesaikan soal PISA pada konten kuantitas pada siswa kelas X SMAN 2 Takalar yang berkemampuan tinggi, sedang dan rendah. Penelitian ini merupakan penelitian kualitatif yang dirancang untuk mengetahui kemampuan matematis siswa dalam menyelesaikan soal PISA pada konten kuantitas. Data yang diolah adalah data kemampuan matematis siswa yaitu kemampuan penalaran matematis, kemampuan representasi matematis, dan kemampuan pemecahan masalah matematis. Teknik pengumpulan data yang digunakan adalah pemberian tes, dan wawancara. Soal yang digunakan dalam tes mengukur kemampuan matematis adalah soal-soal yang diadaptasi dari PISA yang berjumlah 3 soal. Berdasarkan hasil analisis, diperoleh bahwa subjek dengan kemampuan tinggi memiliki ketiga kemampuan matematis, yaitu kemampuan penalaran matematis, kemampuan representasi matematis, dan kemampuan pemecahan masalah matematis. Subjek dengan kemampuan sedang hanya memenuhi dua kemampuan matematis, yaitu kemampuan penalaran matematis, dan kemampuan representasi matematis, sedangkan kemampuan pemecahan masalah matematis belum terpenuhi karena Subjek dengan kemampuan sedang mampu mengidentifikasi masalah tetapi kurang mampu merencanakan atau menyelesaikan masalah dan pemeriksaan. Subjek dengan kemampuan rendah hanya memenuhi satu kemampuan matematis yaitu kemampuan penalaran matematis.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pembelajaran guided discovery dalam meningkatkan pemahaman siswa tunanetra. Penelitian ini merupakan penelitian eksperimental dengan desain Single Subject Research (SSR) A-B. Siswa yang digunakan sebagai subjek dalam penelitian ini adalah siswa kelas VII MTs Yaketunis Yogyakarta. Pengumpulan data melalui tes, observasi dan wawancara. Analisis data dilakukan berdasarkan hasil pada fase baseline maupun intervensi yang berada pada dua kondisi, yaitu dalam kondisi dan antar kondisi. Hal ini terlihat dari peningkatan hasil tes pemahaman siswa pada fase baseline dengan skor 43, 41 dan 50 menjadi 80, 83, 81, dan 90 pada fase intervensi. Demikian halnya dengan hasil analisis dalam kondisi yang menunjukkan bahwa fase intervensi memiliki arah kecenderungan arah dan stabilitas yang signifikan lebih meningkat daripada fase baseline. Melalui observasi dan wawancara juga diketahui konsistensi jawaban yang menunjukkan pemahaman konsep sudut siswa sudah terkonstruksi. Dengan pembelajaran guided discovery, siswa tidak hanya sekedar menghafal konsep tapi lebih pada aktivitas belajar bermakna dengan mengonstruksi dan memahami konsep secara mandiri, sehingga hasil belajarnya bertahan lama dalam memori siswa.
