Abstract

This study was aimed at analyzing the difference improvement of statistical literacy of the student teacher candidate in terms of their prior-ability on mathematics (PAM). This study used the Quasi Experiment method with the Non-equivalent Pretest-Posttest Control Group type and a sample of seventy elementary school student teacher candidates. The sampling technique used was purposive sampling method. The results of the research data were then analyzed using an independent sample t-test. Normalized-gain was used to analyze the improvement of students’ statistic literacy abilities. The study results significant differences in statistical literacy. Based on PAM, the group of students who received collaborative problem solving (CPS) models achieved higher statistical literacy improvements than students in the expository group. The improvement of statistical literacy was due to the effectiveness of CPS model. Collaborating can strengthen student statistic literacy skills. The ability of statistical literacy in learning requires students to have good PAM, because the PAM is a combination of knowledge and mathematical thinking skills in collaborating students can be actively involved in dealing with solving challenging statistical problems.KEMAMPUAN LITERASI STATISTIK MAHASISWA CALON GURU DITINJAU DARI KEMAMPUAN AWAL MATEMATIKAAbstrakPenelitian ini bertujuan untuk menganalisis perbedaan peningkatan literasi statistis mahasiswa ditinjau dari kemampuan awal matematis (KAM). Penelitian menggunakan metode Quasi Eksperiment dengan tipe Non equivalent Pretest-Posttest Control Group. Sampel sebanyak 70 mahasiswa calon guru sekolah dasar yang diambil menggunakan metode purposive sampling. Data dianalisis menggunakan uji independent sample t-test. Normalized-gain digunakan untuk menganalisis peningkatan kemampuan literasi statistis mahasiswa. Penelitian menghasilkan adanya perbedaan signifikan peningkatan literasi statistis. Berdasarkan KAM kelompok mahasiswa yang mendapatkan pembelajaran dengan model collaborative problem solving (CPS) mencapai peningkatan literasi statistis lebih tinggi dari mahasiswa pada kelompok ekspositori. Peningkatan literasi statistis dikarenakan efektifnya penggunaan model CPS. Berkolaborasi dapat memperkuat kemampuan literasi statistis mahasiswa. Kemampuan literasi statistis dalam pembelajaran mensyaratkan mahasiswa harus memiliki KAM yang baik, karena KAM merupakan kombinasi antara pengetahuan dan keterampilan berpikir matematis sehingga dalam berkolaborasi mahasiswa dapat terlibat aktif dalam menghadapi dan menyelesaikan masalah statistik yang menantang.

Abstract

Representasi matematis penting bagi mahasiswa untuk menyampaikan ide-ide kreatif terhadap permasalahan statistik. Pentingnya representasi matematis, maka tujuan penelitian ini adalah menganalisis perbedaan peningkatan representasi matematis mahasiswa calon guru sekolah dasar yang difasilitasi dengan menggunakan model collaborative problem solving. Metode yang digunakan adalah Quasi Eksperiment dengan desain Non-equivalent Pretest-Posttest Control Group. Sampel penelitian sebanyak 70 mahasiswa calon guru sekolah dasar. Hasil penelitian menunjukan terdapat perbedaan peningkatan kemampuan representasi matematis mahasiswa, dimana mahasiswa yang mendapatkan pembelajaran dengan model CPS memperoleh N-gain 0,46 lebih tinggi dari kelompok ekspositori dengan N-gain 0,30. Berdasarkan kemampuan awal matematis (KAM), baik level tinggi, sedang, dan rendah kelompok CPS mencapai peningkatan kemampuan representasi matematis lebih tinggi dari kelompok ekspositori (EPS). Perbedaan peningkatan mengindikasikan bahwa penggunaan model CPS dalam perkuliahan statistika pendidikan lebih baik dari model pembelajaran EPS. Peningkatan ini dikarenakan berkolaborasi dilaksanakan dalam kelompok, namun tujuan utamanya bukan untuk mencapai kesatuan yang didapat melalui kegiatan kelompok, tetapi mahasiswa calon guru sekolah dasar didorong untuk menemukan berbagai pemikiran kreatif yang disampaikan setiap individu dalam kelompok.Kata Kunci: Representasi Matematis, Kemampuan Awal Matematis (KAM), Collaborative Problem Solving (CPS) Mathematics representation are important for students to convey creative ideas to statistical problems. The purpose of this study was analyzed the difference in improvement of mathematics representation of students who are elementary school student teacher candidate facilitated by using collaborative problem-solving model. By using Quasy Experimental method with non-equivalent pretest–posttest control group design. The study sample consisted of 70 students of elementary school student teacher candidate. The result showed that there was a difference increase in mathematics representation in which student who were gained in collaborative problem-solving model identified to have N-gain 0, 46 higher than those who were ekspository group with the N-gain 0,30. Based on the prior-ability mathematics (PAM), the higher level, medium, and lower level of students in CPS group increased high mathematics representation than the ekspository (EPS) group. This increased result indicates that the use of CPS model in lectures of educational statistics was better than EPS. This increase internalized that the collaboration was in group but the main objective was of getting the unity gained in the group, but the students urged to get creative thinking recived individually in group.Key words; Mathematics representation, Prior-Ability Mathematics (PAM), Collaborative problem solving (CPS)

Abstract

Mathematical creative thinking skill is important for elementary school students to have so they can be actively involve in solving challenging mathematical problems. Related to this, the purpose of the study is to determine the effect of Drill and Practice (D&P) methods on improving student mathematical creative thinking abilities in terms of their initial Prior-Ability on Mathematics (PAM). The study used a Quasi Experiment method with the type of One Group Pre test-Post test Design and involved 22 students as a research sample that were selected pro positively. To analyze the increase in mathematical creative thinking abilities used Ngain. The result showed that there was an influence of the D&P method on improving student mathematical creative thinking abilities in terms of PAM. Further tests using the Post Hoc Test showed that high PAM level >< moderate there was no difference, while high PAM >< low and moderate >< low there was a difference. Each PAM level achieved an increase in the medium category. The increase is due to the effectiveness of the D&P method. The D&P method can trigger an increase in student creative thinking skills because students Practice working on questions and Practice on contextual problems. This process allows students to explore their creative thinking abilities

Abstract

The purpose of this study was to find out the relationship between statistical literacy and mathematical representation of students as pre-service elementary school teachers through the Collaborative Problem Solving (CPS) model. The relationship between statistical literacy and mathematical representation was analyzed by using a product-moment correlation with a sample of 35 students of Elementary School Teacher Education Study Program at one of the state universities in Ambon City. The results showed that there was a positive and strong relationship between statistical literacy and mathematical representation with a correlation value of 0.66. This relationship means that if students have good mathematical representation abilities, statistical literacy abilities are also getting better. Exploration of statistical literacy and mathematical representation abilities can be facilitated by using The CPS learning model. The CPS learning model can facilitate student learning as a structure in mathematical thinking so that statistical literacy and mathematical representation abilities of students can be explored through the transformation of ideas among students. The CPS learning model aspects were implemented in high and very high categories while the indicators were at rating-2 and rating-3.
