As we know, generally, at least there are two types of learning that we have already experienced until right now, they are rote learning and meaningful learning, where each type has itself characteristic different from each other. The fundamental difference between the two types of learning is that rote learning emphasizes on memorizing structurally meanwhile meaningful learning focusing on understanding concepts learned. Therefore, teachers should carefully consider suitable strategies of teaching before deciding which types of learning could be developed in students’ thinking, and teachers need to pay attention to the effectiveness of teaching and learning in order to help students achieving a conceptual understanding.2018-10-31T15:36:39+07:00##submission.copyrightStatement##http://kalamatika.matematika-uhamka.com/index.php/kmk/article/view/137PENGEMBANGAN PERANGKAT PEMBELAJARAN MATEMATIKA DALAM MENDUKUNG KEMAMPUAN ABAD 212018-11-01T11:27:22+07:00Isna Rafiantiisnarafianti@untirta.ac.idNurul Anrianinurul_anriani@yahoo.co.idKhairida Iskandarkhairidaiskandar@gmail.comThe abilities of the 21st century consist of critical thinking and problem solving, creativity and innovation, communication, and collaboration. To support the development of this capability, it is necessary to design a 21st century mathematics-based learning tool. Based on field observations, teachers have not been able to develop a learning tool that leads to this capability. This is due to the lack of knowledge of teachers in designing such learning. If a teacher understands and is able to design a mathematics lesson that leads to 21st century skills, then as a teacher they will be ready to apply it and, in the end 21st century skills for students will flourish. The research approach that will be used in this research is the development research with the aim of producing the product in the form of lesson plans, student worksheets and standard instruments that support the ability of the 21st century. The development model that will be used in this research is 4D development model which includes four stages: define, design, develop and disseminate. But developers only use three stages. The results show that based on the overall score that has been obtained from the testing process shows that the learning tool of mathematics is very good.2018-10-31T15:36:46+07:00##submission.copyrightStatement##http://kalamatika.matematika-uhamka.com/index.php/kmk/article/view/167KORELASI MODEL GROUP INVESTIGATION DENGAN KEMAMPUAN BERPIKIR KREATIF DAN KEMAMPUAN PEMECAHAN MASALAH2018-10-31T15:54:48+07:00Umar Solehumar.soleh95@gmail.comFerry Ferdiantoferrymatematika@gmail.comSetiyani Setiyanisetiyani_0401509081@yahoo.comThe purpose of this research is to know the relationship of Group Investigation model with creative thinking ability and problem solving ability.

The subjects of this study are 9th grade students of junior secondary school. Subject determination is done using GEFT instrument and mathematics teacher’s consultation, then continued by giving concept comprehension test on Pythagorean theorem material and interview. Checking the validity of data is done by time’s triangulation. The results showed that student: 1) states the meaning of Pythagoras's theorem given in his own language by noting Pythagorean theorem’s definition; 2) when using the concepts of Pythagoras theorem, students use triangle images as representations to facilitate an interpretation of given sides position. Then the students find the unknown values and use Pythagoras theorem to solve the problem; 3) using the necessary condition or sufficient condition of a concept to determine the area of a triangle using Pythagorean theorem by finding a side. While, the results for field independent cognitive style are student: 1) expresses the meaning of Pythagoras theorem by using their own language and mentioning the symbols; 2) using the concepts of Pythagorean theorem to solve the problem given by using multiplication operations to determine one of unknown sides. Then, student use pythagoras theorem to find the answer of the given problem; 3) using the necessary conditions or sufficient terms a concept of Pythagoras theorem by stating that it must be known two sides or not.2018-10-31T15:37:08+07:00##submission.copyrightStatement##http://kalamatika.matematika-uhamka.com/index.php/kmk/article/view/175PENGARUH KECERDASAN LOGIS-MATEMATIS DAN KECERDASAN MUSIKAL TERHADAP HIGHER ORDER THINKING SKILLS (HOTS)2018-11-05T12:14:40+07:00Leonard Leonardleonard@unindra.ac.idNanda Novi Lindanandalindannl@gmail.comThe aim of this study is to test the hypothesis about the influence of logical-mathematical intelligence to higher order thinking skills.
