Abstract

Tujuan dari penelitian ini adalah untuk mendeskripsikan keefektifan pendekatan Contextual Teaching and Learning (CTL) dan problem-solving ditinjau dari prestasi belajar dan kepercayaan diri. Penelitian ini merupakan penelitian eksperimen semu dengan populasi semua siswa kelas VII SMP Negeri 1 Yogyakarta Tahun Ajaran 2015/2016 yang terdiri dari delapan kelas. Sampel penelitian dipilih secara acak, dari delapan kelas yang ada terpilih dua kelas yaitu VII A dan VII B. Kelas VII A sebagai kelas eksperimen I diajar dengan pendekatan CTL dan kelas VII B sebagai kelas eksperimen II diajar dengan pendekatan problem solving. Instrumen yang digunakan dalam penelitian ini adalah tes prestasi belajar dan angket kepercayaan diri siswa. Data dianalisis menggunakan one sample t-test yakni digunakan untuk menyelidiki keefektifan pendekatan CTL dan problem solving; dan Multivariate Analysis of Variance (Manova), digunakan untuk menyelidiki perbedaan keefektifan antara pendekatan CTL dan problem solving. Temuan penelitian menunjukkan bahwa pendekatan CTL dan problem solving masing-masing efektif ditinjau dari prestasi belajar, tetapi tidak efektif ditinjau dari kepercayaan diri siswa pada pembelajaran materi himpunan kelas VII. Untuk perbedaan keefektifan, hasil temuan menunjukkan bahwa tidak terdapat perbedaan keefektifan antara pendekatan CTL dan problem solving ditinjau dari prestasi belajar dan kepercayaan diri. The effectiveness of the CTL and problem-solving approaches in terms of the achievement and self-confidence AbstractThe purpose of this study is to describe the effectiveness of Contextual Teaching and Learning (CTL) and problem-solving approaches in terms of achievement and self-confidence. This study was quasi-experiment research with the entire population of the seventh-grade students of State Junior High School 1 Yogyakarta in 2015/2016 which consisted of eight classes. The research sample classes VIIA and VII B were randomly selected from the eight classes. Class VII A as the experiment class I was taught by using the CTL approach and class VII B as the experiment class II was taught by using the problem-solving approach. The instruments of the study were an achievement test and the students’ self-confidence questionnaire. The data were analyzed using a one-sample t-test to investigate the effectiveness of CTL and problem-solving approach; and Multivariate Analysis of Variance (Manova), to investigate the difference between the effectiveness of CTL and problem-solving approaches. The research findings indicate that the CTL and problem-solving approaches each are effective in term of achievement, but it’s not effective in term of and self-confidence in the teaching of the set topic to the seventh-grade students. For differences ineffectiveness, the findings indicate that there is no difference between the CTL and problem-solving approaches in terms of students’ achievement and self-confidence.

Abstract

Students should have a good mathematical connection ability to support their learning success. Many factors affect the mathematical connection ability, in­cluding prior knowledge and emotional intelligence. This study aimed to des­cribe the simultaneous and partial effect of students’ prior knowledge and emo­tional intelligence on mathematical connection ability. This study involved 34 ninth graders of one of the public junior high schools in Lembang Regency, Indonesia, as the sample. The data was collected using a test consisting of a prior knowledge test and a mathematical connection ability test on the circle topic, and a questionnaire to measure students’ emotional intelligence. We ana­lyzed the collected data by descriptive statistics, multiple regression, and partial correlation. The results revealed that the prior knowledge and emotional intelli­gence together had a significant effect on mathematical connection ability, with a contribution of 23.6%. In addition, there was a significant positive effect bet­ween prior knowledge and mathematical connection ability with a contribution of 75.1% and a significant positive effect between emotional intelligence and mathematical connection ability with a contribution of 12.2%.

Abstract

Tujuan penelitian ini adalah untuk mendeskripsikan learning trajectory ber­basis proyek yang dilalui siswa untuk memahami definisi himpunan. Penelitian desain ini menggunakan model Gravemeijer dan Cobb dengan tahapan yang terdiri atas: (1) preparing for the experiment yang mencakup penyusunan hypo­thetical learning trajectory (HLT); (2) design experiment yang mencakup pe­laksanaan pembelajaran berdasarkan HLT yang telah dirancang; dan (3) retro­spective analysis, yaitu membandingkan HLT dengan pembelajaran yang dilak­sanakan. Pengembangan HLT menjadi learning trajectory diperoleh melalui serangkaian aktivitas yang dilaksanakan dengan pengumpulan data melalui dokumentasi, observasi, dan wawancara dengan guru dan siswa untuk meng­klarifikasi dan mengonfirmasi alur belajar. Hasil penelitian mengindikasikan bahwa pembelajaran berbasis proyek dapat memfasilitasi siswa dalam mema­hami definisi himpunan. Learning trajectory definisi himpu­nan berbasis proyek diperoleh melalui serangkaian aktivitas dengan empat level pemodelan. Level situasional berupa aktivitas survei kumpulan objek di sekolah. Pada level refe­rensial, istilah “ciri-ciri yang sama”, “dapat didefinisikan”, dan “objek tambah­an”, dan “kesepakatan” muncul melalui diskusi. Pada level generalisasi, siswa me­nuliskan himpunan dalam bentuk yang lebih umum. Ter­akhir, pada level for­mal, pemahaman yang siswa peroleh dari setiap aktivitas merupakan modal un­tuk membangun konsep tentang definisi himpunan.Project-based learning trajectory on the definition of the set topicAbstractThis research aimed to describe the project-based learning trajectory pass­ed through by students to understand the set definition. This design research used Gravemeijer and Cobb model with stages: (1) preparing for the experiment that includes developing hypothetical learning trajectory (HLT); (2) design of expe­riments which includes learning practices implementation based on the deve­loped HLT; and (3) retrospective analysis, which was to compare HLT with learning practices. The development of HLT into a learning trajectory was ob­tained through a series of activities carried out by collecting data through docu­mentation, observation, and interviews with the teacher and students to clarify and confirm the learning trajectory. The results indicated that project-based learning could facilitate students to understand the definition of set. The lear­ning trajectory was obtained through a series of acti­vities with four levels of modeling. The situational level was in the form of a survey activity aimed to collect objects in the school area. At the referential level, the terms “common features”, “definable”, “additional objects”, and “agree­ment” emerged thro­ugh discussion. At the generalization level, students wrote the set in a more general form. Lastly, at the formal level, the under­standing that students get from each activity was a provision to construct a concept about set definition.

Abstract

Semiotics are signs that include codes, symbols, words, icons, objects, or gestures. This descriptive-qualitative study aimed to describe the semiotics of mathematics problem-solving in Mason’s generalization. Generalization is a finding pattern process in which students will use the different strategies with some semiotics. The subjects were three of 30 eleventh graders from a senior high school in Gresik Regency, Indonesia, that were selected using the purposive sampling technique. Data was collected through documentation, written test, and interview. Data was analyzed by reducing data, presenting data, and concluding. The results of this study showed that students could present the semiotics of gesture, word, and symbols in the process of Mason’s generalization, even though in several stages or indicators the students could not present semiotics. The absence of semiotics in several stages or indicators was not because students could not do such things, but because students passed or skipped these stages. In the perception of generality stage, the semiotics of gesture, word, and symbols could emerge simultaneously. However, for expression of generality, symbolic expression of generality, and manipulation of generality stage, students did not present the three semiotics’ components simultaneously.

Penelitian kualitatif ini bertujuan untuk men­deskripsikan proses metakognisi mahasiswa calon guru matematika dalam menyelesaikan soal Piramida Hitung (Pitung) yang merupakan permasalahan non rutin terkait operasi bilangan bulat. Subyek penelitian adalah tiga maha­siswa Pendidikan Matematika Universitas Kristen Satya Wacana Salatiga angkatan 2019. Kriteria pemilihan subyek yaitu: mahasiswa yang berhasil memecahkan tiga tantangan dalam Pitung (tepat dua operasi hitung, tepat tiga operasi hitung, dan tepat empat operasi hitung), komunikatif, dan bersedia menjadi subyek. Data dikumpulkan melalui tes tertulis, think aloud, dan wawancara. Hasil penelitian menunjukkan bahwa proses metacognitive awareness (menyadari pengetahuan dan pengalaman terdahulu, menyadari pola strategi yang dibuat, dan menggunakan informasi pada soal untuk penyelesaian masalah), metacognitive regulation (membuat perencanaan, merevisi langkah penyelesaian, memikirkan dan menemukan jawaban lain), dan metacognitive evaluation (menilai kapasitas berpikir, menilai hasil pekerjaan, dan menilai pemahaman diri sendiri) terjadi saat  proses pemecahan masalah dengan bentuk beragam untuk setiap subjeknya. Selain itu, metakognisi juga membantu subyek dalam membuat strategi penyelesaian menjadi lebih efektif. The process of metacognition of prospective mathematics teachers in solving number pyramid problemsAbstractMetacognition was one of the determining factors for a person’s success in problem-solving. This qualitative research aimed to describe prospective tea­chers’ metacognition process in solving the Number Pyramid or Piramida Hi­tung (Pitung) problem, non-routine problems related to integer operations. The subjects were three mathematics education students of Universitas Kristen Satya Wacana Salatiga, Indonesia. The criteria for selecting subjects, namely: students were succeeded in solving three challenges in the Pitung (exactly two-number operations, three-number operations, and four-number operations), communicative, and willing to be the subject. Data were collected using the written test, think aloud, and interviews. The results showed that process of metacognitive awareness (be aware of previous knowledge and experience, be aware of the pattern of strategies created, and use the information in problems for problem-solving); metacognitive regulation (made plans, revised comple­tion steps, think about, and found others answers); and metacognitive eva­luation (assessed thinking capacity, assessed work results, and assessed self-understanding) occurred during the problem-solving process in various forms for each subject. Also, metacognitive helped the subjects in making the comple­tion strategy more effective.

Abstract

This study aims to describe proportional reasoning skills and students’ difficul­ties in solving proportional reasoning problems. The population of this research was 3480 seventh-grade students of state junior high schools in the Yogyakarta region. The samples were 158 students chosen using proportionate stratified random sampling that represent four categories of school (very high, high, me­dium, low) based on the average scores of the national examination in mathe­matics in 2016. Data were collected through essay tests and interviews. Data were analyzed quantitatively and qualitatively. The result showed that the stu­dents in very high and high category schools had moderate proportional rea­soning ability. Students in medium and low category schools had low propor­tional reasoning ability. Students’ difficulties in solving proportional reasoning problems vary based on the type of the problem, such as the difficulty in finding the multiplicative relationship contained in the problem, the difficulty in under­standing the value of inverse proportion, and the difficulty in explaining the obtained solution of the problems.
