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.

The purpose of this study is to describe the errors made by students when solving problems on the material of circles and conic sections. The method used in this study is a qualitative descriptive method. The subjects in the study consisted of 30 students of the Mathematics Education Study Program, IKIP Siliwangi Bandung. The instrument of this research is a written test in the form of a description of 4 questions. The data processing was carried out in three stages, namely the reduction stage, the presentation and drawing conclusions from the data. Based on the results of the study, it showed that students' errors in solving analytic geometry problems consisted of conceptual, procedural and technical errors. The causes of conceptual errors are student errors in stating the formula used when solving the problems presented, students do not understand the material and do not know how to solve problems. The cause of procedural errors is that students lack practice when completing the given practice questions, students do not understand the process of solving problems correctly. The cause of technical errors is the lack of skill of students in the process of calculating in an operation and students' inaccuracy in the calculation process, less thorough and in a hurry when solving problems so they do not re-check what has been done

Online learning is a new alternative for the continuity of learning activities during the Covid-19 period, where learning is carried out online through various media or ICT used. This research aims to see the analyze how difficult students mathematical in working on mathematical problems, especially in quadrilateral and triangular material. The subject of this study were students of class VII at MTs Negeri Kabupaten Bandung Barat. The instrument used were written tests in the form of essays which numbered 5 questions and a student questionnaire via a google form. This research method uses descriptive analysis, to find out the student's mistakes in solving problems. Processing data is calculated in the form of average student scores obtained by analysis used on Taksonomi Bloom cognitive. The results showed that students achievement in the process of solving triangular and quadrilateral problems based on the stage of Taksonomi Bloom is based on the stage of Taksonomi Bloom, namely, at the cognitive stage the most is in stage C5 and C6 there is evaluation and creation, then in C2, C3, and C4 also still less than 60%. Thus it can be seen that the level of student understanding of rectangular and triangular material is still relatively low so that there is difficulty in solving students' problems on rectangular and triangular material based on Taksonomi Bloom stages. Keywords: student difficulties, online learning, quadrilateral, and triangular, taxonomy bloom
