Abstract

This study aimed to know whether students’ mathematical representation ability reach the classical completeness and to describe students’ mathematical representation based on their thinking style, namely Concrete Sequential (CS), Abstract Sequential (AS), Abstract Random (AR), and Concrete Random (CR). This study used mixed methods as the research design. Population in this study was 10th graders in one vocational school in Pati. The sample was a class chosen randomly. The subjects of this research were 8 students consisted of 2 of every thinking style type. The methods of data collection of this research were questionnaires of thinking style, mathematical representation ability test, interviews, and documentation. The results showed that: (1) students’ mathematical representation ability reached the classical completeness and (2) the students’ mathematical representation ability based on their thinking style are (a) the CS students have moderate visual ability, excellent symbolic ability, and poor verbal ability; (b) the AS students have moderate visual ability, excellent symbolic ability and less verbal ability; (c) the AR students have moderate visual and verbal ability, and good symbolic ability; and (d) the CR students have moderate visual ability, excellent symbolic ability, and poor verbal ability.

Abstract

This study aimed to test the effectiveness of 7E-learning cycle learning with realistic approaches for students' mathematical representation ability and describe the students' mathematical representation ability from the view of students' curiosity. This study used a mixed-method with a concurrent embedded model. The population of this study was 8th graders in a Junior High School in Patebon, Kendal. Random sampling was used to obtain 32 students for the experiment class and 32 students for the control class. For the qualitative analysis, two students for each high, medium, and low curiosity level were selected. Questionnaires, tests, interviews, and documentation were used to collect data. T-test, classical completeness Z-test, the mean difference test, and proportions different tests were used to analyze the data quantitatively. Meanwhile, qualitative data were analyzed using data reduction, data display, conclusion drawing, and verification. The results show that 7E- learning cycle learning with realistic approaches affected students' mathematical representation abilities positively. The study also revealed that students with high, medium, dan low curiosity levels show different perform in mathematics representation.

Abstract

Tujuan penelitian ini adalah untuk mengetahui apakah pembelajaran dengan model Thinking Aloud Pair Problem Solving (TAPPS) tuntas, apakah rata-rata kemampuan pemecahan masalah siswa pada model TAPPS lebih tinggi daripada rata-rata kemampuan pemecahan masalah siswa pada pembelajaran ekspositori, serta apakah persentase ketuntasan belajar siswa pada model TAPPS lebih tinggi daripada persentase ketuntasan belajar siswa pada pembelajaran ekspositori. Populasi penelitian ini adalah siswa kelas VIII SMP N 2 Pekalongan tahun pelajaran 2012/2013. Dengan teknik cluster random sampling, terpilih sampel yaitu siswa kelas VIII-D sebagai kelas eksperimen yang diterapkan pembelajaran model TAPPS berbantuan worksheet berbasis Polya dan kelas VIII-B sebagai kelas kontrol yang diterapkan pembelajaran ekspositori. Dari hasil uji ketuntasan belajar diperoleh pembelajaran pada kelas eksperimen tuntas. Dari hasil uji perbedaan dua rata-rata, diperoleh rata-rata kemampuan pemecahan masalah siswa kelas eksperimen lebih tinggi daripada kelas kontrol. Dari hasil uji proporsi satu pihak, diperoleh persentase ketuntasan belajar siswa kelas eksperimen lebih tinggi daripada pada kelas kontrol. Simpulan yang diperoleh yaitu pembelajaran dengan model TAPPS tuntas, rata-rata kemampuan pemecahan masalah siswa pada model TAPPS lebih tinggi daripada rata-rata kemampuan pemecahan masalah siswa pada pembelajaran ekspositori, dan persentase ketuntasan belajar siswa pada model TAPPS lebih tinggi daripada persentase ketuntasan belajar siswa pada pembelajaran ekspositori.Kata kunci: keefektifan, kemampuan pemecahan masalah, thinking aloud pair problem solving, TAPPS

Abstract

Penelitian bertujuan mengembangkan model pendampingan lembaga kemahasiswaan dengan menerapkan metode penelitian dan pengembanga penelitian telah menghasilkan buku profil mahasiswa berprestasi, dan model pendampingan lembaga kemahasiswaan yang telah divalidasi. Hasil uji coba skala terbatas telah mendapatkan data tentang kinerja pengurus lembaga kemahasiswaan sebagai dampak penerapan model. Kinerja mahasiswa dinyatakan baik dengan skor rata-rata 3,5 dari skor maksimal 4. Sesuai hasil penelitian sementara yang telah dihasilkan, maka dapat diambil kesimpulan yaitu; model pendampingan lembaga kemahasiswaan yang dikembangkan dalam penelitian ini mendapakan penilaian layak dari pakar model dan pakar kebahasaan.The research aims to develop a model mentoring student organizations to implement research methods and research has produced a book pengembanga profile outstanding students, student organizations and mentoring models that have been validated. Limited scale trial results have obtained data about performance management student body as a result of application of the model. Otherwise good student performance with an average score of 3.5 out of a maximum score of 4. According to the research results while has been generated, it can be concluded that; student organizations mentoring models developed in this study mendapakan worthy of an expert assessment model and a linguist.

Abstract

General Linguitics subject is a fundamental subject offered to semester 1students hoping to be the foundation for the students to understand other linhuisticsubjects. However, the students’ achievement in the subject was not yet optimum. Thesubject of the study was 400 freshmen of Indonesian language and literature studyprogram of Indonesian Language and Literature Department of Semarang StateUniversity who took general linguistic class. The study applied classroom actionresearch with two cycles. The results of the research were that the assessment andacademic tutorial for students in general linguistic could improve the students’ gradeand knowledge. This was shown from the improvement of the the pretest, formativetest, and posttest at the end of cycles 1 and II. The sum of the score of the pretest,formative test, and posttest at the end of cycle I are subsequently 1810, 2875, and2981. The average score of the three assements improved from 50.3 to 71.9 and 74.5.At the end of the cycle II the score improved from 3196 to 3384 with the averagescore improving from 81.7 to 84.6. Besides, the assessment and student academictutorial could change the behavior of the students who attended general linguisticclass. This was seen from the more positive change of the students’ behavior. With theplanned activities and obtained result, the writer suggests/recommends that thisactivity is applied to other subjects.Kata kunci : asesmen, tutorial, linguistik umum
