Abstract

Students' ability for HOTS is critical to acquire. However, the PISA survey in 2018 showed that Indonesian participants were at level 1, and the national exam in 2018 indicated that 40% of students had an issue answering HOTS questions. The problem suggests that students solve questions requiring higher-order thinking skills, causing errors. Therefore, the study aimed to analyze student errors based on Newman's Theory in solving HOTS-based math story problems. The method applied for qualitative research with a descriptive approach. Data collection involved 126 grade IX students using HOTS-based math story tests, interviews, and documentation. Students were grouped into three categories from the HOTS-based math story test results: students with good, medium, and low abilities. This step was to find the average and standard deviation of the scores obtained by respondents when completing the given test. Then three students were selected from each category as subjects. The results showed that as many as 50% of students misunderstood the questions, 20% made transformation errors, and 10% errors in reading, processing skills, and encoding. The high error rate of these students shows the poor ability of students to solve HOTS-based math story problems.

Abstract

A well-constructed concept can aid pupils in comprehending any learning content. However, as seen by how students solve math problems, the construction process frequently encounters flaws. Students make various conceptual construction errors in online learning. This is a qualitative study conducted on Mathematics Education students of Universitas Papua. The purpose of this study was to determine the errors made by students in constructing concepts of functions during online learning. Five subjects were selected as the subjects. They were chosen by using the purposive sampling technique. The instrument was developed using material from online lectures on functions and has been validated by experts in the field of mathematics education. The findings indicated that there were five misconstruction concepts, i.e. pseudo construction, construction holes, mis-logical construction, mis-analogical construction, and misconstruction in problem-solving. For further research, to avoid unnecessary construction errors, it is recommended that before the learning process is carried out, the teacher should know the construction of students’ concepts, so that the process of students’ conceptual change in online learning can be known.

Abstract

Tujuan penelitian ini untuk mengetahui kemampuan pemecahan masalah matematika siswa kelas XI IPA III SMA N 2 Manokwari pada materi penerapan turunan berdasarkan teori Polya melalui penerapan model pembelajaran kooperatif tipe teams games tournament (TGT). Penelitian ini menggunakan metode kualitatif dengan menggunakan teknik deskriptif. Hasil penelitian ini menunjukkan bahwa dalam mengerjakan soal, siswa tidak mengacu kepada teori pemecahan masalah matematika menurut Polya secara sempurna. Terjadinya kelemahan ini disebabkan penerapan model pembelajaran kooperatif tipe TGT mengharuskan siswa mengerjakan soal dengan memanfaatkan waktu seefisien mungkin

Abstract

Abstract:  The purpose of this study is to find out what are the obstacles for mathematics educators in implementing distance learning during the COVID-19 pandemic. The method used in this study is a qualitative method using descriptive techniques. The research subjects in this study were mathematics educators at YAPIS Manokwari High School. Based on the results of the interview, the results of this study indicate that there are several obstacles in the implementation of distance learning. Constraints experienced in learning include human constraints where teachers are still not optimally using the applications used for the learning process. Some teachers are not proficient in using applications as a medium for learning.Abstrak: Tujuan penelitian ini adalah untuk mengetahui apa saja kendala pendidik matematika dalam melaksanakan pembelajaran jarak jauh dimasa pandemi COVID-19. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan menggunakan teknik deskriptif. Subjek penelitian pada penelitian ini adalah pendidik matematika di SMA YAPIS Manokwari. Berdasarkan hasil wawancara, hasil penelitian ini menunjukkan bahwa ada beberapa yang menjadi kendala dalam pelaksanaan pembelajaran jarak jauh. Kendala yang dialami dalam pembelajaran meliputi kendala manusiawi dimana guru masih belum secara maksimal menggunakan aplikasi yang digunakan untuk proses pembelajaran. Ada beberapa guru yang belum mahir dalam penggunaan aplikasi sebagai media untuk pembelajaran.

Abstract

Penelitian ini bertujuan untuk mengetahui efektifitas pembelajaran daring berbantuan moodle terhadap prestasi belajar mahasiswa ditinjau dari karakter rasa ingin tahu dan self-efficacy. Metode penelitian yang digunakan oleh peneliti merupakan penelitian kuantitatif. Desain penelitian yang digunakan yaitu Nonequivalent Control Group Design yang merupakan salah satu jenis desain penelitian dari Quasi Experimental Design. Populasi penelitian merupakan seluruh mahasiswa jurusan pendidikan matematika dan sampel penelitian adalah mahasiswa yang memprogram mata kuliah pembelajaran matematika SD. Teknik pengumpulan data terdiri dari tes tertulis, kuisioner, wawancara, dan dokumentasi. Teknik analisis data terdiri dari analisis data kevalidan dan analisis data keefektifan meliputi uji ketuntasan prestasi belajar, uji perbedaan rata-rata prestasi belajar, uji pengaruh karakter rasa ingin tahu dan self-efficacy terhadap prestasi belajar. Hasil penelitian menunjukkan pembelajaran daring berbantuan moodle efektif meningkatkan prestasi belajar mahasiswa ditinjau dari karakter rasa ingin tahu dan self-efficacy dengan kriteria: (1) Proporsi ketuntasan belajar klasikal dapat dikatakan lebih dari 75 % mahasiswa memperoleh nilai 70 atau B , (2) Prestasi belajar mahasiswa pada kelas yang menggunakan pembelajaran daring berbantuan moodle terintegrasi karakter rasa ingin tahu lebih baik daripada prestasi belajar mahasiswa dengan pembelajaran konvensional, (3)Terdapat pengaruh karakter rasa ingin tahu (X1) dan self-efficacy (X2) secara bersama-sama terhadap prestasi belajar posttest (Y). Abstract  This study aims to determine the effectiveness of Moodle-assisted online learning on student learning achievement in terms of curiosity and self-efficacy. The research method used by researchers is quantitative research. The research design used is the Nonequivalent Control Group Design which is a type of research design from Quasi-Experimental Design. The research population is all students majoring in mathematics education and the research sample is students who are designing elementary mathematics learning courses.

Abstract

One of the important components in educational evaluation is assessment. This study aims to develop an assessment instrument for PjBL-based learning in mathematics at a driving school in Manokwari district. The research method used by the researcher is research and development with a 4D development model (Define, Design, Develop, and Disseminate). This research procedure consists of this includes 4 stages, namely the stage of defining (define), design (design), development (develop) and dissemination (disseminate). The data collection technique used in this study is the method of observation, instrument validation, and interviews. The assessment instrument was validated with a content validity ratio approach, then its reliability was tested with the SPSS-assisted Cronbach Alpha test. Research Results a) The PTS Assessment Instrument for collaborative projects between subjects obtained an average of 3.67 from the validator. The average validation score is in the very good category. Based on the results of the validation, it can be concluded that the instrument to be used is valid. b) The reliability test of the PTS assessment instrument for the collaboration project between subjects in 7th grade boys and 7th graders obtained Cronbach's alpha reliability coefficient values of 0.749 and 0.774, respectively, where both values were between 0.7 and 0.9 so that it could be concluded that the instrument to be used has high reliability.Keywords: Project Based Learning, Subjects Collaboration, Sekolah Penggerak, Research Instruments
