Abstract

This study aims to determine the response of students to the implementation of learning-based project learning model to determine the student's ability to develop RPP through the application of learning-based project learning model and student response in project based learning learning between experimental class and control class. This research method is quasi experimental method with pretset-posttest control group design design. The study population is all students of STKIP Siliwangi who follow the course of High School Mathematics Learning Planning in the even semester of the academic year 2016/2017 consisting of 3 classes, namely: B1, B2, and B3. For the sample of the study, two classes were selected from the study population, selected B1 class as a control class consisting of 40 students and B2 class as experimental class consisting of 43 students. The sample is selected not random class. Data analysis was done to the difference of mean of student ability test result in preparing RPP and percentage from questionnaire of student response to learning of project based learning. The results showed that most of the students gave positive responses to the application of learning-based learning model with average of pretest and posttest class percentage of experiment respectively 67,49% and 77,09% including strong category. Meanwhile, the average of pretest and posttest percentage of control class were 61.50% and 63.97%, respectively. Improvement of students ability in preparing RPP through the implementation of learning model project based learning average gain of 0.57 experimental class included in the category while the control class of 0.36 medium category; And the improvement of the students' ability in preparing the lesson plan that obtained the application of project based learning model is higher than that obtained the application of conventional learning model.

Abstract

Penelitian ini bertujuan untuk mengetahui hambatan mahasiswa dalam belajar mata kuliah program linear. Metode penelitian ini adalah deskritif kualitatif. Populasi penelitian adalah seluruh mahasiswa pendidikan matematika STKIP Siliwangi Bandung yang mengikuti mata kuliah program linear. Subjek penelitian adalah mahasiswa pendidikan matematika STKIP Siliwangi Bandung yang mengikuti mata kuliah program linear pada semester genap Tahun Ajaran 2016/2017 semester 4. Untuk memperoleh data penelitian digunakan instrumen berupa tes diagnostik dan wawancara. Hasil penelitian didapat kesimpulan: (i) tingkat kemampuan mahasiswa awal pembelajaran masih level rendah; (ii) kesalahan mahasiswa pada umunya belum memahami soal dan prakonsep masih rendah; (iii) mahasiswa belum tertanam rasa belajar secara mandiri. Adapun solusi untuk mengatasi hambatan tersebut melalui latihan atai drill soal secara terstruktur dan memberikan soal yang beragam sebagai bahan untuk berlatih. Dosen mencoba menggunakan metode yang berbeda setiap pertemuan di kelas agar mahasiswa tidak mudah jenuh dan berlatih berpikir solusi terhadap persoalan  program linear.

Abstract

Kemampuan berpikir kreatif merupakan kemampuan siswa untuk menemukan jalan penyelesaian yang tidak biasa, unik, dan belum pernah ditemukan oleh orang lain. Pengembangan konsep berpikir kreatif matematis dapat membuat siswa putus asa dan menyerah, sehingga dibutuhkan sebuah kemampuan lain agar siswa mampu bertahan dan mampu mengubah kesulitan-kesulitan yang ditemui menjadi peluang untuk dirinya lebih maju. Kemampuan yang dimiliki seseorang dalam mengamati kesulitan dan mengolah kesulitan tersebut dengan kecerdasan yang dimiliki sehingga menjadi sebuah tantangan untuk diselesaikan dikenal dengan  Adversity Quotient (AQ). AQ terdiri dari 3 tipe, yaitu climber, camper, dan quitter.  Penelitian ini merupakan penelitian deskriptif kualitatif. Penelitian ini bermaksud untuk mengetahui bagaimana tingkat kemampuan berpikir kreatif matematis  dalam menyelesaikan soal kubus dan balok di tinjau dari Adversity Quotient tipe Climber. Penelitian dilaksanakan pada semester genap tahun pelajaran 2019/2020 di SMP Negeri 2 Ngamprah, kelas VIII  yang berjumlah 31 siswa dan  subjek dalam penelitian ini adalah 2 siswa. Metode pengumpulan data yang digunakan dalam penelitian ini meliputi: 1) tes yang digunakan untuk mengetahui kemampuan siswa dalam berpikir kreatif matematis; 2) wawancara yang berdasarkan tugas. Hasil penelitian menunjukkan bahwa siswa climber melakukan proses berpikir asimilasi pada tahap memahami masalah, menyusun rencana penyelesaian, menyelesaikan masalah sesuai perencanaan, dan memeriksa kembali hasil yang telah diperoleh dan memiliki kemampuan untuk mengerjakan soal-soal berpikir kreatif pada indikator fluency, felexibility. AbstractThe ability to think creatively is the ability of students to find ways of solving that are unusual, unique, and have never been found by others. The development of the concept of mathematical creative thinking can make students despair and give up, so that another ability is needed so that students are able to survive and be able to change the difficulties encountered to become opportunities for themselves to advance. The ability possessed by a person in observing difficulties and cultivating these difficulties with intelligence possessed so that it becomes a challenge to be solved is known as Adversity Quotient (AQ). AQ consists of 3 types, namely climber, camper, and quitter. This research is a qualitative descriptive study. This study intends to find out how the level of mathematical creative thinking ability in solving cubes and beams is reviewed from the Adversity Quotient type of Climber. The study was conducted in the even semester of the school year 2019/2020 in Ngamprah Middle School 2, class VIII which amounted to 31 students and the subjects in this study were 2 students. Data collection methods used in this study include: 1) tests used to determine students' abilities in mathematical creative thinking; 2) task-based interviews. The results showed that the climber students did the assimilation process of thinking at the stage of understanding the problem, preparing a settlement plan, solving the problem according to the plan, and re-examining the results that had been obtained and having the ability to work on creative thinking questions on the indicator of fluency, flexibility.

Abstract

This research is motivated by the low ability of mathematical creative thinking of high school students of class X IPA. To overcome these problems required one of the learning models are expected to develop creative thinking skills and mathematical disposition of students is based on Alternative Solutionss Worksheet. Through this learning, students are directly involved and learn to come up with ideas in solving open ended problems, so that the students interest to be active during the learning process. It is expected that through this learning, students become motivated, resilient.The output form of this research is an open ended alternative worksheet solution which can be utilized by teachers for teaching materials. The research method used is quasi experimental with design form of Nonequivalent Control Group Design, where the research subjects are not grouped randomly. The data in this study were collected through the pretest and postes of mathematical ability as well as the scale of the students' mathematical disposition. The results of this study are classes that use learning alternative solution worksheet better than conventional class.
