<![CDATA[The background of this research is the inability of students to understand mathematical concepts. The researcher chose the demonstration method with the help of GeoGebra Software to overcome the lack of understanding of mathematical concepts. The purpose of this research is to find out whether there is an effect of the demonstration method with the help of GeoGebra Software on the ability to understand mathematical concepts. This research is a Quasi-experimental study where the design applied is Nonequivalent Control Group Design. The population of this study were 79 students of class IX at SMP Muhammadiyah 2 Purwokerto. The research sample consisted of 26 students from class IXA which were used as the experimental class and 27 students from class IXB which were used as the control class. The test instrument is used to measure the ability to understand each student's mathematical concepts. The N-Gain test shows that the control group has an average N-Gain of 0.29 which is in the low category, while the experimental group has an average N-Gain of 0.61 which is in the medium category. The average difference in the percentage of pretest and posttest scores on all indicators of mathematical understanding ability in the control class was 9.75% while in the experimental class was 13.68%. From the t test, the value of sig = 0.004 < α = 0.05 means that there is a difference in the average N-Gain value of the experimental class and the average N-Gain value of the control class. The conclusion from this study is that there is an influence of the demonstration method with the help of GeoGebra Software on the ability to understand mathematical concepts in class IX SMP Muhammadiyah 2 Purwokerto.]]>

<![CDATA[This study aims to describe the strategic competencies of prospective teacher students based on cognitive style and gender in formulating, representing and solving problems. This type of research was descriptive qualitative. The supporting instruments were the GEFT (Group Embedded Figure Test) and the task of mathematical non routine problem contained several mathematical concepts, namely circles, trigonometry, and triangles. The research subjects consisted of 2 males Field Independent (FI) and 2 females Field Independent (FI), 6 females Field Dependent (FD) and 4 males Field Dependent (FD). Data was collected through documentation of solving mathematical problem and interview results. The data validity method used method triangulation and referencial adequacy checks. Research datas were analyzed by reducing data, presenting data and drawing conclusions. The results showed that FI females and males were more analytical than FD females and males. FI males and FI females both understood problem situations by drawing, but FI males recognized the circle concept more quickly and confidently than FI females. FI females were more analytical in the process of transferring problem situations into pictures than FI males. FI males and FI females both represented problem situations in pictures and symbols but FI females tended to have more logical pictures and symbols than FI males. FD females tended to understand problem situations by drawing more than FD males, therefore FD females were said to be more analytical in transferring problem situations into pictures compared to FD males. The four types of subjects did not arrive at a correct final solution.]]>

<![CDATA[The students have difference in cognitive style. This research aimed to describe and analyze students’ communication skills and creative thinking skill level in view of field dependent and independent cognitive style on algebraic concept. Algebra communication skill is essential skill needed for solving mathematical problems. Algebra must be mastered by the students because related to other materials. Algebra topic analyzed in this study is quadratic equation word problems. The indicators of communication skill include (1) able to state the situation into mathematical notations, structures or symbols, (2) able to demonstrate and describe unique algorithms in problem solving, and 3) able to construct and explain real-world phenomena in graph, sentence, equation, table or other presentation. The student level of creative thinking skill can be seen from fluency, flexibility and novelty. This research used a mixed-method. The object were 16 students of junior high school in Tangerang. The data collection techniques used test and interview. Cognitive styles are grouped using the Group Embedded Figure Test (GEFT) which divide the students into field dependent (FD) and field independent (FI). The results of the study indicated that algebra communication skill of students with FD and FI were not different significantly in problem solving. Both are able to understand the problems into mathematical expressions, but not all groups state the correct mathematical equations. The students used different strategy to solve the problems. FD students used less detailed strategy, incomplete analysis, think generally, and not quite precise in writing mathematical equations, while FI students provided detailed explanations, better accuracy, think more flexibly, and state mathematical equation precisely. In general, they have same creative level.]]>

<![CDATA[Concepts in mathematics include abstract concepts, especially for elementary students. So that teachers are required to always innovate in learning so that learning is effective, not boring and students more easily understand concepts correctly. This learning requires media that is appropriate to the material and cognitive development of students. The media used in this research is result determining lamp to determine the least common multiple (LCM) and the greatest common divisor (GCF) of a number. This study aims to discuss the effectiveness of result determining-lamp media to determine the results of LCM and GCF in grade IV students at SDN Peterongan Jombang. Effectiveness in research is seen from how the average learning outcomes and whether there are significant differences in student learning outcomes with and without the result determining-lamp media. Sampling uses a saturated sample, so that all class IV is used as a sample. Based on the results of the study, it was concluded that the use of result determining-lamp media is an effective determinant of learning outcomes because the average learning outcomes of the experimental class are higher than those of the control class and through the t-test there are differences in the learning outcomes of class IV students with and without the result determining-lamp media.]]>
