Penelitian ini dilatarbelakangi karena masih rendahnya kemampuan koneksi matematik siswa, dengan tujuan penelitian adalah untuk menelaah pencapaian dan peningkatan kemampuan koneksi siswa SMP melalui pembelajaran menggunakan pendekatan metaphorical thinking berbantuan software Geogebra. Metode pada penelitian ini adalah metode eksperimen dengan dua kelompok yaitu kelas eksperimen dan kelas kontrol, desain penelitian berupa pretest, postest, dan uji gain ternormalisasi. Instrumen tes penelitian terdiri dari 5 soal tes kemampuan koneksi matematik berbentuk uraian. Populasi penelitian ini adalah seluruh siswa SMP di Kabupaten Bandung Barat, sedangkan sampelnya adalah SMP Krida Utama Padalarang. Sampel kelas VIII diambil secara acak kelas dari 12 kelas, diperoleh kelas VIII D sebagai kelas ekperimen, dan kelas VIII C sebagai kelas kontrol. Kelas Eksperimen memperoleh pembelajaran dengan pendekatan metaphorical thinking berbantuan software Geogebra, dan kelas kontrol memperoleh pembelajaran biasa. Data hasil penelitian diperoleh dari hasil pretes, postes , dan uji gain ternormalisasi, yang diolah melalui uji uji normalitas, dan uji Mann-Whitney. Hasil penelitian menunjukan bahwa pencapaian dan peningkatan kemampuan koneksi matematik antasa siswa yang memperoleh pembelajaran dengan pendekatan methaporical thinking berbantuan software Geogebra lebih baik dengan siswa yang memperoleh pembelajaran biasa. Kata Kunci : Pendekatan Metaphorical Thinking, Koneksi Matematik, Software Geogebra   AbstractThis research is motivated because of the low mathematical connection ability of students, with the aim of the study is to examine and improve the access speed of junior high school students through learning using the Geogebra software-assisted metaphor thinking approach. The method in this study is the experimental method with two groups, namely the experimental class and the control class, the research design in the form of pretest, posttest, and normalized gain test. The research test instrument consists of 5 test questions on the ability of mathematical connections to form a description. The population of this study were all junior high school students in West Bandung Regency, while the sample was Krida Utama Padalarang Middle School. The sample of class VIII was obtained directly from the second grade class, grade VIII was obtained as the experimental class, and class VIII C was the control class. Classroom Experiment learning with a metaphorical thinking approach aided by Geogebra software, and ordinary learning control classes. The research data was obtained from the results of pretest, posttest, and normalized gain test, which were processed through the normality test, and Mann-Whitney test. The results of the study showed that connecting and connecting students and students who used the Geogebra software-assisted method of metabolic thinking was better with students who read ordinary learning.

Mathematical Connection

The purpose of this study was to obtain an overview of the mathematical connections of junior high school students on the concepts of ratio and proportion. This research uses a descriptive qualitative method with data triangulation. The research participants were four junior high school students in Sukabumi. The instrument used in this study consisted of a description test of three questions that had been consulted with experts and based on considerations regarding indicators of mathematical connection ability. Based on the results of the study, it is known that the ability of students to recognize and use connections between mathematical ideas is 50%, the ability of students to connect and apply mathematical concepts with other disciplines is 50%, and the ability of students to connect and apply mathematical concepts to problems in everyday life with a percentage of 50%. The results showed that the mathematical connection ability of some junior high school students in Sukabumi on the concept of comparison was included in the poor category.

This research is motivated by the lack of connection capabilities junior high school students in Bandung West. This study will examine the achievement of matemati connection capabilities of students usinglearning reciprocalteaching with the usual approach. The method used is an experimental method to design pretest-posttest control group, ie design involving at least two groups and randomly sampling classes. At the beginning and end of the study both classes were given the test. The population in this sample is the entire junior high school students in Bandung West whose characteristics have a low ability mathematical connections. Of the entire junior high school in West Bandung randomly selected and elected SMP Negeri Bandung Barat representing the characteristics of the population. The sample was selected randomly, where class G into the experimental class VIII, and VIII F be the class of the control. Collecting data in this study using a test description that has been tested first, and then score the mathematical connection capabilities of students were analyzed by descriptive and inferential statistics using two different test average. Based on the results, good data analysis and hypothesis testing, with α = 0.05 mathematical connection capability turns the achievement of students usinglearning model reciprocal teaching is better than the students who used the usual approach

The aim of this study was to investigate the improvement of the students’ attentionafter using there different methods of HICAI-SOI, HICAI-Media, and with out CAIthree exell-1, exell-2 and regularly class.The research method was Quasi-experiment.The sample of the research were 90 persons from class VIII Junior High SchoolStudents 7 Padang, that was selected randomly. Prior knowledge of student as bilinearcovariant is obtained through cognitive domain test and attention score of learning iscollected through questionnaire. The validity and reability of both instrument weretested, and the coefficient 0,83 and 0,92. Result of examination applies bilinearcovariant analyst technique (ANACOVA) factorial 3x3x1, successfully controls initialability equal to 67%. Attention of student learning increases in signifikan from studytrivariable, to three treatment classes [F(2, 253)=183,92, p<0,05] with effect size equalto 59%, difference of class to attention also highly significant [ F(2,253)=8,39, p<0,05]with effect size equal to 6%, medium of interaction influence between various studieswith class also highly signifikan [F(2,253)=8,39, p<0,05] with effect size equal to7%.Result of analysis shows the contribution of various study to increase attention offar bigger than difference of class and interaction. Therefore, the conjecture of thewriter that the attention influences learning process in provable emperical. Thisresearch showed that the student Junior High School Students is more interested tostudy physics with HICAI-SOI. Its gives more impact on the students’ attention atregular class, It is concluded that the use of HICAI can improve the attention of JuniorHigh School Students.

This article is derived from the research result entitled “The Application of Problem Solving Approach in Improving Junior High School Students’ Mathematical Communication and Disposition Skill”. The research is purposed to see and analyze if there are some improvements in mathematical communication and disposition skill achievement of the students who have been treated using problem solving approach compared to the students who are still treated using conventional approach. The population of the research is all students at a junior high school in Subang regency. Out of these students,  40 students of class VIII D were chosen randomly as the experiment class, and 41 students of class VIII C have also been randomly chosen as the control class. The data in this research have then been analyzed using parametric and non-parametric statistic. The result of this analysis has shown that the achievement of experiment class students’ mathematical communication and disposition skill is better than the achievement of the control class students. The experiment class students’ mathematical disposition is also better than those of the control class. Lastly, the result also shows that there is some kind of correlation between the mathematical communication and mathematical disposition on the level of medium.
