Pada masa covid-19 pembelajaran dilaksanakan secara daring (online), sehingga dibutuhkan beberapa alat belajar berbantuan ICT yang mampu menunjang efektivitas pembelajaran dengan baik yaitu Geogebra. Penelitian ini bertujuan untuk menelaah efektivitas pembelajaran berbasis masalah berbantuan Geogebra terhadap kemampuan penalaran matematis. Metode yang digunakan dalam penelitian ini adalah metode kuasi eksperimen. Populasi penelitian ini adalah seluruh siswa SMK Swasta di kota cimahi, sedangkan sampelnya dipilih tiga kelas yang banyaknya 80 dari satu SMK swasta di kota Cimahi. Instrumen yang digunakan dalam penelitian ini adalah seperangkat tes kemampuan penalaran yang berbentuk soal uraian sebanyak 4 soal. Soal tersebut sudah memenuhi soal yang baik berdasarkan validitas, reliabilitas, daya pembeda dan indeks kesukaran. Berdasarkan hasil perhitungan menggunakan SPSS 18 diperoleh hasil bahwa model berbasis masalah dengan bantuan Geogebra dengan model berbasis masalah maupun biasa memiliki nilai sign. sebesar 0,000, karena nilai sign. < 0,05, maka dapat disimpulkan bahwa pembelajaran menggunakan model berbasis masalah berbantuan Geogebra lebih efektif dibandingkan model pembelajaran berbasis masalah maupun model biasa ditinjau dari kemampuan penalaran matematis siswa. Dengan demikian penerapan model berbasis masalah berbantuan Geogebra lebih efektif dibandingkan model berbasis masalah maupun konvensional terhadap kemampuan penalaran matematis. Abstract During the Covid-19 period, learning was carried out online, so it needed several ICT-assisted learning tools that were able to support the effectiveness of learning well, namely Geogebra. This study aims to examine the effectiveness of Geogebra-aided problem-based learning on abilities. The method used in this study is a quasi-experimental method. The population of this study was all private vocational students in the city of Cimahi, while the sample was selected in three classes with a total of 80 from one private vocational school in the city of Cimahi. The instrument used in this study was a set of reasoning ability tests in the form of 4-item description questions. These questions have fulfilled good questions based on validity, reliability, distinguishing features and difficulty index. Based on the results of calculations using SPSS 18 shows that the problem-based model base on Geogebra with problem-based and ordinary models has a sign value. of 0.000, because of the sign value. <0.05, it can be concluded that learning using a Geogebra-assisted problem-based model is more effective than problem-based learning models and ordinary models in terms of students' mathematical reasoning abilities. Therefore the results are obtained the application of a Geogebra-based problem-based model is more effective than a problem-based or conventional model in terms of mathematical reasoning abilities.

This research is motivated by the low ability of mathematics understanding of junior high school students, with the aim of the study is to examine the achievement, improvement, implementation, and difficulty of mathematics understanding ability of junior high school students through learning using Geogebra-assisted scientific approach. The method of this research is an experimental method with two class groups namely experimental class and control class. The population of this research is all junior high school in West Bandung Regency, randomly selected and selected SMP Krida Utama Padalarang. Samples were taken randomly class VIII chosen D as an experimental class, and class VIII C as control class. The experimental level received learning with the Geogebra-assisted scientific approach, and the control class gained regular learning. The results showed that the achievement and improvement of the ability of mathematical understanding between students who received learning with scientific approach assisted Geogebra software better with students who get regular learning. Learning with Geogebra-assisted scientific approach can be implemented in the experimental class by the steps of the scientific method of observing, asking, exploring, associating, and communicating.

Penelitian ini bertujuan untuk mendeskripsikan kesulitan siswa dalam mengerjakan soal pemecahan masalah berbentuk cerita pada materi segitiga dan segiempat. Metode penelitian yang dipilih ialah desktiptif kualitatif, bertujan untuk mendeskripsikan secara jelas dan mendalam informasi yang diperoleh. Subjek penelitian ini adalah 30 siswa kelas VIII MTs Negeri di kota Cimahi. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah tes dan observasi. Berdasarkan hasil penelitian dan analisis jawaban siswa diketahui bahwa siswa mengalami kesulitan yang tergolong tinggi. Kesulitan terbesar yang dialami siswa berada pada tahap melakukan prosedur matematika. Hal ini dapat dilihat pada langkah menentukan strategi penyelsaian masalah yang kurang lengkap, keliru menentukan rencana penyelesaian masalah bahkan beberapa siswa tidak tepat dalam menentukan strategi penyelesaian masalah. Beberapa siswa kesulitan dalam menerjemahkan masalah ke dalam model matematika dan siswa kesulitan memahami masalah.

Visual Basic Application for Excel is a simple program language and has the power to process data quickly. The utilization of math functions in Microsoft Excel can help work on Excel display more interactive so that teachers can create props inside Excel. The advantages of Microsoft Excel than other mathematical software are the many math functions and images available in the form of shapes or pictures. The availability of VBA, math and image functions in Microsoft Excel help teachers to design the creation of media related to mathematics learning, especially to develop the ability of junior high school students who have difficulty to connect mathematics lessons with basic mathematics knowledge requirements. By using VBA for Excel, the ability of junior high school students to improve in the usual way significantly with a t-test with 0.006 0.05. Furthermore, there is an association between the students’ self-confidence and their mathematical comprehension skills with a contingency coefficient of 0.525 including a moderate association.
