PROFIL KONFLIK KOGNITIF DENGAN INTERVENSI DALAM PEMAHAMAN ALJABAR MAHASISWA POLITANI PANGKEP
Full text linkThe study aims at obtaining information on the profile of cognitive conflict of students by giving intervention on understanding Algebra of students at Pangkep State Polytechnic of Agriculture. The research method employed descriptive qualitative. This study involved the students who experienced cognitive conflict as a sample. The instruments used in collecting the data were written test and interview.  Setiap mahasiswa selesai menyampaikan jawaban, akan diberikan informasi baru yang dapat memicu terjadinya konflik kognitif. Each of the students delivered his or her answer: he or she would be given new information that could trigger cognitive conflict. The results of the study reveal that (1) the students experienced cognitive conflict in determining set of completion on inequality  that did not have a zero divisor. Based on students understanding, quadratic inequality that difficult to be factored or the factors were not integers that did not have solutions, (2) the students experienced cognitive conflict in solving equation  that had infinite solutions. The students tended to work procedurally without identifying relational elements formed by the expressions. The subjects did not see the objects produce in first step  that showed experession on the left was equal to the expression on the right side, (3) the students experienced cognitive conflict in determining set of completion on inequality  after giving intervention with new information by talking squares on inequality segment, (4) cognitive conflict happened as well on conceptual understanding of correlation between  denga

PERBANDINGAN KEFEKTIFAN GOOGLE CLASSROM DAN MICROSOFT TEAMS DALAM MENGELOLA KELAS ONLINE
Full text linkLearning Manajemen System (LMS) menjadi salah satu alternatif untuk melaksanakan pembelajaran selama masa Covid-19. Dua diantara LMS yang sudah dikenal oleh masyarakat pelajar yaitu Google Classroom dan Microsoft Teams. Penelitian ini bertujuan untuk membandingkan keefektifan kedua LMS dalam mengelola kelas online agar diperoleh informasi yang lebih jelas tentang kelebihan, kekurangan serta keefektifan masing-masing LMS. Dalam pelaksanaannya peneliti menggunakan dua LMS ini untuk mengajar pada dua kelompok kelas di Universitas Sembilanbelas November Kolaka. Kemudian mengukur dan membandingkan kelebihan dan kekurangan kedua LMS pada beberapa indikator. Instrumen utama dalam menganalisa kelebihan dan kekurangan kedua LMS ini adalah peneliti sendiri. Data diperoleh pada saat proses pembelajaran berlangsung. Semua informasi tentang fungsi fitur kedua LMS dikumpulkan kemudian direduksi sehingga diperoleh data yang jelas yang mempermudah dalam membuat kesimpulan. Data lain berupa hasil belajar mahasiswa juga dikumpulkan menggunakan fitur pengujian masing-masing LMS. Ternyata tidak ada perbedaan yang signifikan antara kedua hasil belajar yang diperoleh. Disisi lain, ada delapan fitur LMS yang masing-masing memiliki keunggulan. Google Classroom unggul dalam hal kecepatan akses, fitur penilaian dan fitur absensi. Microsoft Teams unggul dalam hal penyimpanan data dan komunikasi. Sementara fitur administrasi, pengujian dan penyampaian bahan ajar masing-masing memiliki kelebihan tersendiri untuk kedua LMS masing-masing
Validitas Lembar Kerja Mahasiswa (LKM) Untuk Menumbuhkan Motivasi Belajar Pada Matakuliah Kalkulus Lanjut Di Masa Pandemi Covid-19
Full text linkThe Corona Virus Disease pandemic (Covid-19) requires that conduct online learning and independently including advanced calculus courses. Learning requires students to have a strong motivation to study. The development of Student Worksheets (SW) is a strategy that can foster student motivation. The purpose of this study was to develop a valid SW in growing student motivation. This kind of research was development research, namely the development of SW with the Plomp model: (1) initial investigation, (2) design, (3) realization/ construction, (4) tests, evaluations and revisions, (5) implementation. The subjects of this research were students of Mathematics Education Program in STKIP Andi Matappa. Research instruments: SW validation sheet. The results of the study: the content validity score of the SW is included in the high category. This shows that advanced calculus SW that has been developed meets valid  to foster student motivatio
KOMPARASI KEEFEKTIFAN MODEL PEMBELAJARAN KOOPERATIF TIPE CRH DAN TAKE AND GIVE
Full text linkThis type of research is an experimental unit research unit that aims to: find out the effectiveness comparison between the CRH type cooperative learning model and take and give type on cube and beam material in class VIII of State Junior High School 1 Takalar. The effectiveness of learning, in this case, is when the tests of mathematical learning outcomes, student responses, and student activities, all three have met the criteria of effectiveness. The population in this study was all students of class VIII of State Junior High School 1 Takalar and the sample consisted of two classes, namely the experiment class I was taught using a cooperative learning model type CRH and the experiment class II was taught using the Type Take and Give selected using simple cluster random sampling technique. The results showed that (1) THE CRH type cooperative learning model and take and give type were effectively applied to cube and beam materials, (2) THE CRH type cooperative learning model was more effective than the Take and Give type, (3) The learning and response results of math students of class VIII students who were taught with the CRH type cooperative learning model and take and give type have achieved minimal completion criteria, (6) The minimum completion criteria of math and student response outcomes, taught with a CRH-type cooperative learning model are higher than the Take and Give type

PSEUDO ABSTRAKSI REFLEKTIF DALAM MENYELESAIKAN MASALAH BARISAN BILANGAN
Full text linkThis research is a descriptive study. The research objective was to describe the reflective abstraction process experienced by students. The research subject was a class VIII student. The sampling technique used was purposive sampling. The subjects were chosen because they considered their communication skills which were quite good compared to their peers, making it easier for researchers to explore data. In addition, the selected subjects were students with very satisfying academic achievements compared to their classmates. This study examines and explains the reflective abstraction that the subject does in solving the number sequence problem. The focus of research is the process of reflective abstraction which includes interiorization, coordination, reversal, encapsulation, and generalization. The results showed that the reflective abstraction stage did not guarantee arriving at the correct solution. In this study the subject performs all stages of reflective abstraction starting from interiorization, coordination, reversal, encapsulation, and generalization, but the final solution is wrong. This phenomenon is said to be pseudo-reflective abstraction or pseudo-reflective abstraction

DESKRIPSI PEDAGOGIC CONTENT KNOWLEDGE MAHASISWA PENDIDIKAN MATEMATIKA MELALUI MICROTEACHING
Full text linkPedagogical content knowledge (PCK) is one of the important elements in improving students\u27 understanding because teachers are required to master teaching materials or subject matter (content) and master teaching science (pedagogy). As a mathematics education, students are also required to have PCK skills. This type of research is qualitative descriptive with the aim of analyzing the PCK ability of mathematics education students in microteaching courses as a prerequisite for carrying out PPL activities in schools. The subjects of this study were 34 mathematics education students taking microteaching courses for the 2015/2016 academic year. The results showed that mathematics education students were able to coordinate and compile all parts of the lesson plan well, especially in terms of systematics. This means that they have knowledge of the curriculum well, understand students according to the level of knowledge in secondary schools and know how to conduct evaluations. The results of the description of the implementation of the learning process, it was found that students were still lacking in teaching knowledge and about content, the implementation of learning was not in accordance with the draft that had been compiled and were unable to understand well how to present material according to the learning strategy in the lesson plan. Student PCK in the learning process still has many deficiencies, especially in the content, teaching and student sections
