AbstractStudents' algebraic thinking skills must continue to be developed because they can support success in mathematics. Algebraic thinking relates to generalizing patterns learned at the junior secondary level. During the process of generalizing students use the perception of similarity or proximity. Therefore, the purpose of this study is to describe the algebraic thinking process of junior high school students in generalizing patterns. The approach used is qualitative with 3 research subjects who have different algebraic thought processes. The results showed that junior high school students carried out algebraic thought processes by perceiving images, representing, looking for functional relationships, making generalizations, and applying general formulas. The difference in perception is used early in the activity and in the search for functional relationships. The results of this study can be used in developing mathematics learning strategies so that students' algebraic thinking skills develop. AbstrakKemampuan berpikir aljabar siswa harus terus dikembangkan karena dapat mendukung kesuksesan dalam matematika.  Berpikir aljabar generalisasi dengan generalisasi pola yang dipelajari pada tingkat SMP. Pada saat proses melakukan generalisasi siswa menggunakan persepsi similarity atau proximity. Oleh sebab itu, tujuan penelitian ini yaitu mendeskripsikan proses berpikir aljabar siswa SMP dalam melakukan generalisasi pola. Pendekatan yang digunakan yaitu kualitatif dengan 3 subjek penelitian yang memiliki proses berpikir aljabar yang berbeda. Hasil penelitian menunjukkan bahwa siswa SMP melakukan proses berpikir aljabar dengan mempersepsikan gambar, merepresentasikan, mencari hubungan fungsional, melakukan generalisasi, dan mengaplikasikan rumus umum. Perbedaannya persepsi digunakan di awal kegiatan dan pada kegiatan pencarian hubungan fungsional. Hasil penelitian ini dapat digunakan dalam mengembangkan strategi pembelajaran matematika agar kemampuan berpikir aljabar siswa berkembang.

This study aimed to analyze reading activities in “Bright 2” an English textbook for junior high school students grade VIII in Indonesia by using Bloom’s revised taxonomy. A content analysis was conducted to achieve the research purpose. The findings show that the textbook has dominant reading activities on the cognitive process “analyze” 27% and “apply” 21% of the total 145 reading activities, respectively.  The number of higher and lower cognitive processes in this textbook is almost balanced on 49% of higher order thinking skills and 51% of lesser order thinking skills correspondingly. There is a slight difference between the number higher thinking process and lower thinking process since most reading activities are on “analyze”, which is belong to the higher thinking process while the second most frequent reading activities are “apply”, the lower thinking process. Meanwhile, “apply” and “analyze” is placed on the 3rd and 4th in the taxonomy, it means that the textbook emphasizes the middle cognitive thinking process of Bloom’s revised taxonomy, which is formed by “apply” and “analyze”  thinking process.

Too often it is assumed that mathematically talented students, through some sort of magical osmosis, are inherently good problem solvers. This is not true. Bright junior high school students need to have opportunities to systematically develop, practice, and refine their analytical thinking skills.
