Abstract

The purpose of this study was to investigate the flow of thought of the pre-service mathematics teachers through the answers of a function limit evaluation by formal definition. This study used a qualitative approach with descriptive method. The research subjects were the students of mathematics education department of Universitas Serang Raya, Indonesia. After analyzing the students’ written answers, we interviewed the subjects to get further explanation on their strategies and common mistakes. This study found that based on the students’ results in the function limit evaluation by formal definition, there were common strategies, i.e. (1) preparing the proof and (2) proving. The stage of preparing the proof consisted of (1) determining delta value by the final statement of formal definition, (2) substituting the given f(x) and L process, (3) simplifying value in the absolute sign, (4) solving the inequality, and (5) finding the delta value. The stage of proving consisted of (1) stating positive epsilon, (2) defining delta, (3) stating positive delta, (4) substituting the constants and delta values in the initial statement of formal definition, and (5) solving the inequality to create the final inequality statement of the formal definition.

Abstract

This study aims to develop a guided worksheet to fulfil the needs of students to understand the formal concept of Limit. This was carried out using a developmental study that focuses on content analysis and expert review through substantial analysis, structural design, prototype development and evaluation. The research sample was 95 first-year students, especially those in engineering and science majors who enrolled in Calculus. The data process of instrument development, the data of expert validation, and the data of limited trial were produced in this research. To assess all the research data applied the Q-Cochran and the Cronbach Alpha statistical test. The results are a guided worksheet for limit evaluation in visual form with schematic design and scaffolding or framework type. Expert testing and limited testing showed Asymp.Sig. = 0,088 0,05 and rcoefficient = 0,382 rcritical = 0,2017. It indicates that the items composing this guided worksheet are valid and reliable therefore, they can be used to solve student difficulties related to the formal rules of Limit.

Abstract

Penelitian ini memokuskan pada salah satu aspek daya matematis yaitu representasi matematis yang dikaitkan dengan karakteristik unik pada diri mahasiswa. Karakteristik unik mahasiswa dalam kegiatan belajar menjadi salah satu fokus yang perlu dipertimbangkan dosen dalam merancang pembelajaran untuk mengoptimalkan kemampuan yang dimiliki mahasiswa. Salah satu karakteristik unik yang dapat ditelusuri pada diri mahasiswa adalah kecenderungan pola kepribadian yang dalam penelitian ini merujuk pada pola kepribadian Hippocrates Galenus yaitu Sanguinis, Melankolis, Kholeris, dan Phlegmatis. Tujuan dari studi ini adalah mendeskripsikan representasi matematis mahasiswa dengan tipe kepribadian Sanguinis. Deskripsi representasi matematis tersebut didasarkan pada hasil pekerjaan mahasiswa dalam menyelesaikan soal matematika. Ada empat indikator teknis representasi matematis yang dijadikan ukuran dalam menganalisis hasil pekerjaan mahasiswa. Metode yang digunakan untuk mengetahui gambaran representasi matematis mahasiswa tipe Sanguinis dalam penyelesaian soal adalah menyelesaikan soal dengan wawancara (task-based interviews).

Abstract

Perkembangan ICT pada sektor pendidikan memberikan peluang baru, pengaruh baik dan kontribusi positif dalam peningkatan kualitas pada proses kegiatan belajar mengajar siswa termasuk pembelajaran matematika. Hal tersebut menjadi tantangan bagi guru sebagai pemegang sentral dalam proses pembelajaran di kelas. Untuk itu mengembangkan dan meningkatkan profesionalisme pedagogis guru dalam mengintegrasikan teknologi pada pembelajaran merupakan upaya yang mutlak dilakukan. Fokus utama program pengabdian ini adalah memberikan sosialisasi dan pelatihan baik secara teori maupun praktik dalam pengembangan bahan ajar matematika berbantuan Mathematics Education Software yang bertujuan untuk memberdayakan dan meningkatkan keterampilan guru matematika khususnya pada jenjang SMP dan MTS di sekolah swasta Kecamatan Taktakan Kota Serang. Target khusus program pengabdian ini yaitu perbaikan kualitas pembelajaran, peningkatan kompetensi pedagogik dan pengembangan profesionalisme guru matematika SMP dan MTS swasta. Metode yang digunakan untuk mencapai tujuan tersebut adalah metode Apprenticeship Participatory Learning and Action. Tahap inti dalam program pengabdian ini melibatkan guru matematika SMP dan MTS swasta secara langsung sebagai peserta yang mengikuti serangkaian kegiatan yaitu (1) knowledge sharing penggunaan ICT dalam proses KBM matematika, (2) sosialisasi urgensi menggunakan bahan ajar berbantuan ICT dalam pembelajaran matematika dan pengenalan Mathematics Education Software, (3) eksplorasi Mathematics Education Software dan implementasinya pada pembuatan bahan ajar, dan (4) praktik pembuatan dan penyusunan bahan ajar matematika berbantuan Mathematics Education Software. Secara umum perolehan data ditemukan bahwa kegiatan ini memberikan pengaruh baik dan respon positif dari guru-guru dalam mengembangkan bahan ajar matematika berbantuan Mathematics Education Software.

Abstract

[Bahasa]: Penelitian ini bertujuan untuk menguji apakah ada perbedaan peningkatan kemampuan pemecahan masalah antara mahasiswa yang mendapat pembelajaran dengan pendekatan keterampilan fungsional matematis dan pembelajaran konvensional. Pendekatan penelitian kuantitatif dengan desain kuasi eksperimen digunakan untuk mencapai tujuan tersebut. Mahasiswa semester dua yang mengambil mata kuliah Kalkulus II pada jurusan pendidikan Matematika, Universitas Serang Raya dijadikan sebagai populasi penelitian. Sebanyak dua kelas ditentukan secara purposive random sampling untuk sampel penelitian, selanjutnya dinamakan kelas eksperimen dan kelas kontrol. Kelas eksperimen yaitu kelas yang mendapat pembelajaran dengan pendekatan functional skills mathematics sementara kelas kontrol adalah kelas yang mendapat pembelajaran konvensional. Hasil uji statistik menunjukkan bahwa tidak terdapat perbedaan rata-rata capaian namun terdapat perbedaan peningkatan (N-Gain) kemampuan pemecahan masalah di kedua kelas. Hal ini menunjukkan bahwa kemampuan pemecahan masalah mahasiswa di kelas eksperimen cenderung meningkat. Kata kunci: Keterampilan Funsional Matematis; Pemecahan Masalah; Quasi Eksperimen [English]: This study aims to examine whether there are differences in improvement of problem-solving ability between students who received learning with the approach of functional skills mathematics and conventional learning. Quantitative research with quasi experiment is used to achieve that goal. The second semester student who enrolled on Calculus II in the Mathematics Education Department, Universitas Serang Raya were the population of research. Two classes were determined by purposive random sampling for the sample of research, called experimental class and control class. The experimental class was taught using functional skills mathematics while the control class was taught by the conventional learning. The results of the statistical tests show that there is no difference in average performance but there is difference in N-Gain problem solving skills in both classes. This research concludes that problem-solving ability of students in the experimental class tends to increase. Keywords: Functional Skills Mathematics; Problem Solving; Quasi Experiment
