This study aimed at identifying how did the improvement in the problem-solving ability of learners work in improving the ability of learners in constructing the materials obtained after the development of LKPD (Learner’s Worksheet) in classroom learning. This research used Research and Development (R & D) approach using the Kemp model. Data collections were done through problem-solving tests, validation analysis, and correlation test. The indicators of this study included the effectiveness of the developed learner’s worksheet and the increased ability of problem-solving that was seen from the learning results obtained. The results showed that the average increase in the learning outcomes of the learners was equal to 79.44 with a difference in the scores of learning outcomes where tcount = 32.806 > ttable = 1.734, with a significance level of 0.000. Also, the improvement of learning outcomes on the response of learners gives significant influence with a score of 0.338 with a significance level of 0.085. Based on these results the development, the problem-solving oriented students’ worksheet is declared valid and effective based on the results of validation tests by experts and the results of the implementation of classroom learning. These results impact the students’ learning outcomes. It is expected that in the learning process with different materials, the worksheet can be applied in improving students' ability to solve problems. It is suggested for a research to collaborate the worksheet with other models and, media that can be linked to the problem-solving aspects, so that in its implementation, students have the confidence to succeed, be more active, and interested in problem-solving given.
Penelitian ini bertujuan untuk mengetahui hasil belajar dan respon mahasiswa terhadap pembelajaran matematika secara blended learning pada masa pandemic covid-19. Penelitian ini merupakan Kuantitatif pre-experimental dengan desain one group pretest-postest. Instrumen dalam penelitian ini adalah tes hasil belajar mahasiswa peneliti menggunakan lembar tes dengan penerapan pembelajaran matematika blended learning, dan angket respon mahasiswa yang digunakan untuk mengetahui respon mahasiswa terhadap pembelajaran matematika blended learning. Hasil penelitian ini menunjukkan bahwa penerapan pembelajaran matematika blended learning cenderung meningkakan hasil belajar mahasiswa dengan nillai rata-rata 60,56, sedangkan respon mahasiswa terhadap pembelajaan daring diperoleh nilai rata-rata 3,02 dengan kategori Positif. Berdasarkan uraian diatas sehingga dapat disimpulkan bahwa penerapan pembelajaran matematika secara blended learning memberikan subangsih terhadap hasil belajar dan mahasiswa semester V program studi pendidikan matematika Universitas muhammadiyah Sorong merespon positif.
This research is a Classroom Action Research (PTK), which aims to improve the learning outcomes of mathematics through NHT type cooperative learning model in students of class VIII A MTs. Muhammadiyah conducted collaboratively between researchers and teachers of mathematics studies. In the implementation of this research, it is done by giving group worksheet and observation sheet of student activity using NHT type cooperative learning model after giving an explanation about Pythagoras Theorem material as much as two cycles that cycle I and II. After being given group worksheets then conducted the assessment includes assessment of test results of a cycle I and cycles II and group worksheet to students that is by applying learning model of cooperative learning type NHT. The subjects of this study were students of class VIII A which amounted to 20 students consisting of 15 male students and 5 female students. Techniques of collecting data in research are this observation and test. The data obtained were then analyzed. The results of the study showed that the implementation using NHT type cooperative learning model on Pythagoras Theorem material. the ability of students in solving problems on the material above has increased. With the increase of the average value of students in the first cycle was 43.45 and increased in cycle II 83.90. Improvement of student learning outcomes to mathematics learning using NHT type cooperative learning is good. This is indicated by the average value of group learning outcomes in cycle I 60.00 or being in the medium category and the average score of the learning outcomes of the group in cycle I 82.50 or in the high category. This shows the result of increased mathematics learning after conducting cooperative learning model of NHT type
Penelitian ini bertujuan untuk mengetahui efektivitas penerapan model probing-prompting ditinjau dari kemampuan berpikir kritis siswa. Populasi penelitian ini adalah seluruh siswa kelas VIII SMP Negeri 9 Kota Sorong tahun pelajaran 2017/2018 yang terdiri dari 8 kelas. Sampel penelitian ini adalah siswa kelas VIII-C yang dipilih dengan teknik purposive sampling. Desain penelitian ini adalah one shot case study. Instrumen penelitian ini adalah tes uraian berpikir kritis. Berdasarkan hasil analisis data, persentase siswa yang memiliki kemampuan berpikir kritis dengan baik kurang dari 65%. Dengan demikian, model probing-prompting tidak efektif ditinjau dari kemampuan berpikir kritis siswa.
Proses pembelajaran di kelas masih banyak dilakukan secara konvensional, hal ini berdampak pada aktivitas dan respon peserta didik dalam pembelajaran yang dilaksanakan oleh guru lebih membosankan yang mengakibatkan peserta didik kurang aktif, kurang termotivasi dalam pembelajaran. Adapun tujuan dalam penelitian ini adalah untuk mengindentifikasi respon peserta didik dalam implementasi lembar kerja yang berorientasi pemecahan masalah. Metode penelitian menggunakan pendekatan kuantitatif, data yang dikumpulkan berupa lembar respon peserta didik dan wawancara. Populasi sekaligus sampel yang digunakan yakni peserta didik kelas XI MIA SMA Muhammadiyah Al Amin Sorong yang berjumlah 18 peserta didik. Hasil penelitian menunjukkan bahwa rata-rata persentase respon peserta didik terhadap implementasi Lembar kerja peserta didik adalah 77,78 %, persentase tersebut sudah termasuk dalam kategori setuju yang lebih dominan, artinya kriteria tersebut termasuk dalam kategori positif. Dari rata-rata perolehan itu, 22,22 % atau sebanyak 4 peserta didik menjawab sangat setuju terhadap implementasi Lembar kerja tersebut Temuan ini memperjelas bahwa persepsi akan respon peserta didik terhadap pelaksanaan pembelajaran menggunakan Lembar kerja peserta didik berorientasi pemecahan sangat positif dan juga memicu peningkatan kemampuan peserta didik dalam mengikuti pembelajaran. The process of learning in the classroom is still mostly done conventionally; this has an impact on the activities and responses from learners in the lessons learned by the teacher is more over and over which resulted in less active students, less motivated in learning. The purpose of this research is to identify the perceptions of the learners' responses to the implementation of the problem-oriented learner workbook. The research method using the quantitative approach, the data collected in the form of responders letters and interviews. Population, as well as samples used, are students of class XI MIA SMA Muhammadiyah Al Amin Sorong which amounted to 18 students. The results showed that the average percentage of learners' response to the implementation of the learner's worksheet is 77.78%, the percentage is already included in the agreement on category more dominant, meaning the criteria were included in the positive category. From the average of the acquisition, 22.22% or as many as four students answered strongly agree on the implementation of the Worksheet. This finding make clear that the perceptions of the learners' response to the implementation of learning to use the worksheet oriented solving very positive and also trigger an increase in ability learners in following the lesson.
