Abstract

It is difficult for junior high school teachers to position and nurture their students who are still in transition in creative thinking when solving math problems. This study evaluates students' creative thinking process based on Wallas model (2014). The four stages of the creative thinking process according to Wallas include the preparatory, incubation, illumination, and verification phases. The purpose of this study is to describe the creative thinking process of students based on their basic ability level in solving math problems. This research applies giving test of geometric crater thinking ability by looking at homogenous student in kemampuandan interview for deepening. Subjects of junior high school students who categorized on the ability of high, medium, and low after the ability test. Variable of this research is the existence of junior high school students in solving math problems. By using qualitative descriptive method, data is analyzed through classification stage, data representation, and conclusion. In order to complete the results of data groupings used interview techniques to perform data triangulation. The results showed 1) there were 23.33% of students not complete and only reached the preparation stage, called the low category category; 2) there are 60% of students reach the illumination stage even though to this stage students take a long time, called the middle category category; And 3) 16.67% of students have been completed until the verification stage, called the high category category. Based on the deepening of the triangulation of the interviews, the students are correct in that category. For students with low and medium capability categories still require assistance when experiencing barriers to their creative thinking process, while high ability category students need enrichment material

Abstract

Since 1945 the national education curriculum has undergone several times the changes and improvements. In 1947, 1952, 1964 and 1975 teacher-centered learning, whereas from 1984 curriculum involves students learning begin. Similarly, in the 2004 curriculum shades of constructivism learning, where students construct their own concepts or mathematical material. The 2004 curriculum continues with the Education Unit Level Curriculum (SBC) 2006. The education unit level curriculum in 2006 was replaced by Curriculum 2013. Where 2018 is expected all educational units have implemented this 2013 curriculum. Curriculum 2013 is different from the previous curriculum in teaching and learning approaches. Learning in the Curriculum 2013 using a scientific approach: to observe, ask, try, associate and communicate. In mathematics, the old paradigm of the learning process according to Locke that a child's mind as blank paper is clean and ready was often painted his teacher. Piaget said that knowledge is found, created and developed by the students. Maslow said that education is a personal interaction between students and between teachers and students. Good constructivism, RME, and the curriculum in 2013, teachers are required to make the students construct their own learning outcomes. Representation or model can appear in a variety of ways. This paper presents how a mathematical proof or material starting with the use of drawings or models, without mathematical symbols. Theorem to be proved, usually using logical symbols. At first mathematical proof is not easy. Before formally proven, starting with the learning of mathematics using informal evidence that without words, just use the image or geometry.
