Abstract

Abstract. The purpose of this research is to describe process and development result of 4 C's indicators that aligned with curriculum 2013 on the first semester mathematics subject of seventh grade junior high school. 4 C's indicators are indicator of ability that exist in P21 which consist of critical thinking, creative, collaboration and communication. Research type which is used in modified Plomp's development model. Plomp's development phases consists of 4 phase which are, (1) initial investigation phase; (2) designing phase; (3) realisation/ construction phase; (4) test, evaluation, and revision phase. The developed learning materials consist of the number patterns; Cartesian field; Relations and functions; Equation of straight line and sisterm of two linear equations. The development is done by making the 4 C's indicator that aligned with the curriculum 2013. The data collection process is done through product validity test which has been developed by several lecturers and teachers. Validation results were analyzed to conclude that the 4 C's indicator developed was valid after a revision based on the suggestion of some experts with validity criteria greater than or equal to 3.20. Keyword: Plomp's development model, 4 C's indicators, Curriculum 2013

Abstract

This study aims to describe the visual thinking process of mental retardation students in understanding quadrilateral by using origami as the media. Visual thinking in this study is based on the visual-steps of thinking according to Balton (2011). Visual thinking can be used to help students with mental retardation in understanding geometry’s object which has abstract characteristic. Origami media is used as a learning media to improve the visualization ability of students with mental retardation. The type of this research is descriptive research with qualitative approach to give more emphasis on the visual thinking of the mental retardation students than the result of his work. This research was conducted on two mental retardation students of grade nine in SLB Negeri Jember. The instruments of this study are interview guidelines, questions, origami media and validation sheets. The results showed that mental retardation students with assisted origami media could understand rectangles and rectangles based on their properties, determine angles, determine diagonals on rectangles and define diagonal definitions. Keywords: visual thinking, metal retardation students, origami media

Abstract. This study aim to knows the creative thinking in solving the problem of sub-topic of triangle and quadrilateral based on adversity quotient (AQ) of class VII E Junior High School at Nuris, Jember. Data collection methods used in this study are questionnaires, tests and interviews. The instruments used are the Adversity Response Profile (ARP) questionnaire, creative thinking ability test in the form of open matter of triangle and quadrilateral material and interview. Of the population of 24 students VII class E was taken as many as 3 students is students who have high AQ value (climber), students who have AQ value being (camper), and students who have low AQ (quitter). That the climber students in the research more precisely have the creative level according to the transition category from camper to climber, camper students in this study according to the camper student category, but in this research quitter students exceed the category of quitter students, more precisely quitter students in research creative according to the transition category from quitter. Keywords: Creative thinking, problem solving, adversity quotient.

Abstract

This research aims to analyze the errors which are made by students who use auditorial learning style in solving the problem about curved-side geometry based on Newman Method. There are 3 instruments which are used, they are learning style's questionnaire that is a modification of learning style's questionnaire (VAK) that was developed by V Chislett MSc & A Chapman to gain students' subject uses auditorial learning style, the problems which consist of 3 problems in form of stories about curved-side geometry to know the students' error by using the indicators for each error based on Newman method, and interview guideline the factors which cause the errors. Based on the result of the analysis of learning style's questionnaire which was given to IX-H grade students of SMPN 2 Genteng, it showed that there were 10 students with visual learning style, 10 students with auditorial learning style, and 16 students with kinesthetic learning style. The least percentage of error was 6,66% for reading error, while the most error was for transform error (problem transformation) with 79,99%. Keywords: Newman's error analysis, learning style, students with auditorial learning style

Abstract. The rainbow connection of the graph of G = (V, E) if for each pair of points u and v in G there is a path with points u and v as the end points on each side obtaining different colors, the path is called the rainbow path. The rainbow-connected number graph G is the smallest positive integer such that G has a rainbow connection staining denoted rc(G). While the graph is said to be a rainbow 2-connected staining on G if for each pair of points u and v on the sides there are 2 different paths, with u and v being the end points of each side obtaining different colors and 2 passages can not intersect each other, denoted rc2 (G). Let G be the graph connected with so that , with d is degrees. Let G be a rainbow so that where κ is the number of paths of rainbow connecting every two distinct points in G. The results of this research are new theorem about the rainbow connection and 2-rainbow connected. Keywords : rainbow connection, 2-rainbow connected, rainbow path

Abstract

Metacognitive skills is one of the skills that help students in learning math. One way to strengthen students' metacognitive skills by using collaborative learning. This research aims to describe the students’ metacognitive skills in the stages of prediction and evaluation skills by using collaborative learning about Pythagorean theorem at Islamic’s School One Atap Jember. The subject of this research is all students of class VIII B that consist of 20 students in each class. Then, they were formed in 4 study groups, so each group consisted of 5 students. The results in this study were obtained through the students worksheet at the collaborative learning and interview process by representatives of each group. Based on the results of students worksheet, the stage of prediction skills in exploration and transformation learning stage could be fulfilled by the four groups. While the evaluation skill at the reflection learning stage only be met by two groups, the other groups did not meet it because they have not justify the step or the calculation process that has not been appropriate. Based on the results of interviews from the four representatives of the group it can be seen that the prediction skills only be met by two representative groups, that are students with high and medium skilled. Keywords: Metacognitive skills, collaborative learning, prediction skills, evaluation skills.

Abstract

The process of combinatorial thinking is one type of thought process that learners must possess. The combinatorical thinking process provides systematic steps in problem solving. This study aims to determine the process of combining student thinking in solving the sequence and series problem. This research is descriptive research with qualitative research. The method used in this research is test and interview. The subject of this study consisted of four students from one classes. Four students represent each level in the combinatorial thinking process. The indicator of the combinatorial thinking process used Students are able to express the concepts of sequence and series, Students are able to explain what is known in the sequence and sequence. Students are able to change the sequence and series into the mathematical sentence. Students are able to write down what is asked in the matter of the line and series, Students are able to solve the problem of sequence and series until the solution or answer, Students are able to answer about the sequence of sequence and series using the concept of sequence and series, Students are able to describe the reason or cause of the answer. Level one students tend to be able to write down what is known and asked questions correctly, second-level students tend to be able to change the known and asked questions at level one with mathematical sentences. Students with level three tend to be able to do the matter with the calculations and concepts correctly, and Students with level four tend to be able to describe and explain the conclusions of the workmanship Keywords: thinking process, combinatorial thinking, sequence and series.
