Pembelajaran matematika dengan pendekatan PQI ini menggunakan model problem solving dengan strategi pemberian pertanyaan (questioning). Pertanyaan-pertanyaan yang diberikan bertujuan untuk mengarahkan siswa berpikir dan bernalar untuk menyelesaikan masalah sesuai dengan langkah pemecahan masalah Polya yaitu (1) memahami masalah (understanding the problem), (2) merencanakan cara penyelesaian (devising a plan), (3) melaksanakan rencana (carrying out the plan), dan (4) melakukan pengecekan kembali terhadap semua langkah yang telah dikerjakan (looking back).Desain penelitian untuk memperoleh data mengenai kemampuan penalaran geometris siswa menggunakan bentuk pra-experimental design yang digunakan adalah One-Shot Case Study dimana suatu kelompok diberi perlakuan kemudian diukur hasilnya. Populasi dalam penelitian ini adalah siswa kelas VIII SMP Negeri 5 Yogyakarta. Sampel penelitian adalah 32 orang siswa kelas VIII.7 SMP Negeri 5 Yogyakarta yang telah memiliki kemampuan awal yang cukup untuk mempelajari konsep.Instrumen yang digunakan pada penelitian ini adalah soal tes kemampuan penalaran geometris. Pendekatan PQI efektif apabila persentase siswa yang memenuhi ketuntasan secara klasikal pada tes kemampuan penalaran geometris minimal mencapai 75%, dan proporsi siswa yang telah mencapai skor kemampuan penalaran geometris minimal kategori tinggi mencapai lebih dari atau sama dengan 75%. Hasil tes kemampuan penalaran geometris siswa menunjukkan bahwa pendekatan PQI efektif untuk meningkatkan penalaran geometris siswa. Hal ini dikarenakan persentase siswa yang mencapai KKM pada tes kemampuan penalaran geometris adalah 75%.

One way that can be done to complement the shortcomings of teaching materials is to design an LKPD. LKPD is made using the CTL approach. Based on this, a CTL-based student worksheet (LKPD) was developed on set material for class VII students. This study aims to 1) produce CTL based LKPD that meets valid criteria 2) produce CTL based LKPD that meets practical criteria and 3) produces CTL based LKPD that meets the effective criteria. This is a development research with 4-D models. consists of four stages of development that is define, design, develop and disseminate. This research is only up to the stage of define, design and develop. Define’s  stage consists of : a) front end analysis b) student analysis c) concept analysis d) task analysis. Design’s stage consists of : a) LKPD design b) instrument design and validation of instrument penilain module. Develop’s stage consists of : a) the stage of validity  b) the stage of practicability an c) the stage of effectiveness. The results of this study indicate that based on the validator's assessment, The developed LKPD meets very valid criteria with an average of 89,14%. Based on the results of filling the practical questionnaire for educators, practical questionnaire for students and interviews with students showed that LKPD which was developed very practically was used in the mathematics learning of set material with an average of 88,20% by educators and 84,20% by students. Based on the results of the analysis of learning outcomes obtained the average value of the pre test is 59,9655 and the post test average value was 79,3793, then carried out the hypothesis with the t-test. From the calculation results obtained 5,0493 and  thus  with a confidence level of 95%.
