The ability to think critically is one of the highest levels of ability. Developing critical thinking skills in students is still considered important to be improved in schools so that students are able and accustomed to facing various problems around it. This study aims to analyze the critical thinking skills of junior high school students who are in excellent classes and regular classes. This research was conducted in Bandung Barat. In this study students are given a test in the form of questions with critical thinking skills, the problem is used to compare between the superior class and ordinary class. Assessment of the problem using several factors of critical ability include 1) students can not understand the problem correctly, 2) students rush in doing the problem, 3) the students cannot choose the problem-solving strategy correctly and 4) the students work on the problem systematically. Then the matter of critical thinking skills of mathematics is analyzed using quasi-experimental research method to analyze students' critical thinking ability that influence learning result. This study shows the differences in critical thinking ability of junior high school students who are in excellent class and ordinary class. This study shows that superior classes are better in mathematical critical thinking ability than a regular class. The results of this study can add knowledge about critical thinking mathematics junior high school students who are in the class and ordinary class and used to facilitate for educational practitioners in the development of critical mathematical thinking skills.

The focus of this research is to develop learning instruments in the form of LAS based on creative activities to be used in classroom learning and analyze the relationship between the use of LAS in improving students' creative thinking abilities. The type of research used is development research (research & development). The population of this study were all students of Class VIII and IX of MTs Negeri Rantauprapat in the 2017/2018 Learning Year through purposive sampling technique. The instrument used consisted of LAS Validity Sheet and Activity Questionnaire Sheet and Creative Thinking Ability Test. The data obtained in this study will be analyzed for its reliability and analyzed the relationship between the use of LAS in learning and the improvement of students' creative thinking skills. Validation analysis of the questions was in a valid category with an index of tcount> tTable that was 4.426> 2.04; from the aspect of reliability, the index r11 = 0.53 is obtained, namely the medium category; The difference between questions has an average index of 0.365 which is good, and the difficulty level of the questions has a diverse index so that the questions presented are good enough and suitable for use in learning in schools that want to prioritize students' creative activities. Based on the results of the analysis of the average difference between students 'creative thinking skills before and after using creative based LAS, it was found that the improvement of students' creative thinking ability increased significantly by looking at the Gain index before and after using LAS of 3.157.

Mata pelajaran matematika saat ini merupakan pelajaran yang masuh ditakuti oleh banyak siswa-siswa dari tingkat dasar sampai tingkat menengah atas. Hal ini mendorong setiap mahasiswa sebagai calon guru harus memiliki kemampuan untuk memunculkan ide baru untuk mengatasi kesulitan siswa-siswa untuk belajar matematika. Salah satunya adalah mahasiswa harus menciptakan media pembelajaran menggunakan alat peraga. Tentunya alat peraga yang dibuat akan membutuhkan waktu yang tidak sebentar. Oleh sebab itu, TIK merupakan suatu media yang paling efektif untuk menciptakan alat peraga yang berupa visual dan menjadikan belajar matematika siswa menjadi aktif dan menyenangkan. Program yang digunakan oleh mahasiswa adalah Microsoft Excel dengan menggunakan bahasa program Visual Basic Application. Program tersebut membantu mahasiswa-mahasiswa menciptakan kemampuan kreatif matematika untuk membuat media pembelajaran matematika yang baru berdasarkan pernyataan dari berbagai obyek yang dibentuk menjadi sebuah media. pembelajaran yang dilakukan dengan menggunakan pendekatan problem posing dimana dari satu pernyataan sebagai masalah yaitu gambaran-obyek obyek yang tersedia akan disusun dalam komputer, tugas mahasiswa-mahasiswa membuat cara yang berbeda yang dijalankan dengan Visual Basic Application for Microsoft Excel. Penilaian kreatif mahasiswa-mahasiswa dapat dilihat saat tugas awal pembuatan karyanya dan akhir pembuatannya dan akan terlihat seberapa besar perubahan kreatif mahasiswa yang lebih baik saat menggunakan Visual Basic Microsoft Excel, dan penilaian tersebut menggunakan uji t pada dua kelas untuk melihat perbedaan rata-rata dua kelas yaitu pembelajaran matematika yang menggunakan TIK yang menggunakan pendekatan problem posing dang cara biasa.
