Menurut Branch (2009), pengembangan suatu produk berpusat kepada mahasiswa, salah satu strategi yang paling banyak dikenal untuk membantu mahasiswa memahami dan mengingat materi yang dibaca mahasiswa adalah Strategi PQ4R (Preview, Question, Read, Reflect, Recite dan Review). Strategi ini membantu mahasiswa untuk menata informasinya secara bermakna, mengajukan, pertanyaan, merefleksi, dan mengulasnya. Langkah-langkah dalam strategi PQ4R dapat membantu mahasiswa dalam mengorganisasi teks, dan mengatur dirinya sendiri untuk memperoleh informasi lebih mendalam dengan elaborasi yang lebih luas. Sehingga mahasiswa lebih mandiri dalam belajar. Kemandirian dalam belajar diistilahkan dengan Self Regulated Learning. \u0000Model Pengembangan bahan ajar analisis real untuk memfasilitasi self regulated learning mahasiswa yaitu dengan model ADDIE. Tahapan ADDIE adalah (1) Analisis, (2) Perancangan, (3) Pengembangan, (4) Implementasi dan (5) Evaluasi. Kelayakan dan kualitas bahan ajar ditentukan dengan indikator valid, praktis, dan efektif. Validitas bahan ajar ditilik pada aspek materi dan desain bahan ajar, dan praktikalitas dilihat pada uji coba terbatas kepada 10 mahasiswa.

The subject of limited trials was one lecturer and 20 mathematics education students from the FKIP Jambi University. While the subject of field trials was conducted in one class, namely the regular student class in the mathematics education program, 2016/2017 school year. The results show that textbooks and research instruments meet valid criteria. This can be shown from the presentation of the average score of the expert assessment for the economic mathematics textbook that is equal to 84.3%, while the percentage of the average score for the research instrument is 82.8%. The research textbook fulfills the practicality criteria based on the assessment by the lecturers who are in the good category. Textbooks and research instruments meet the criteria of effectiveness based on the results of the observation sheet of the activity of students who meet good criteria of 85.6%, the results of higher order tests thingking skills are 84.2%, and positive student response","PeriodicalId":33561,"journal":{"name":"Edumatica Jurnal Pendidikan Matematika","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43865468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
