“…Sulistyoningsih (2015) mengutarakan keterampilan berpengaruh positif terhadap pemecahan masalah. Dari pendapat Simanungkalit (2015), keterampilan yang dimiliki siswa dapat diterapkan untuk memecahkan masalah yang bersifat tidak rutin. Kurangnya keterampilan ini yang menyebabkan subjek penelitian tidak mampu menyelesaikan soal dengan tepat, hal ini disebabkan oleh: a. Kesalahan yang disebabkan kesalahan data yang digunakan dari proses sebelumnya yaitu memahami dan merencanakan.…”

AbstrakPenelitian ini bertujuan untuk mendeskripsikan jenis-jenis kesalahan yang dilakukan siswa dalam menyelesaikan masalah faktorisasi aljabar. Jenis penelitian ini merupakan penelitian deskriptif kualitatif. Subjek dari penelitian ini adalah siswa-siswi kelas VIII SMP Negeri 35 Semarang. Data-data pada penelitian ini diperoleh dari hasil observasi, tes tertulis dan wawancara. Berdasarkan hasil analisis dan triangulasi data bahwa dari 27 subjek penelitian, sebanyak 3 dari 27 siswa melakukan jenis kesalahan reading errors, 17 dari 27 siswa melakukan jenis kesalahan planning errors, 23 dari 27 siswa melakukan jenis kesalahan skill errors dan 25 dari 27 siswa melakukan jenis kesalahan finishing errors. Adapun penyebab dari banyaknya kesalahan yang dilakukan siswa adalah kurang terbiasanya siswa mengerjakan masalah-masalah yang disajikan berupa masalah atau sol non rutin.

“…The development of mathematics handouts should be tailored to the needs and characteristics of students. This is reinforced by Rick Hunter Simanungkalit who says that the development of learning devices that do not fit the needs and characteristics of students will have an impact on the learning stages of students (Simanungkalit, 2016). The reason for the importance of developing mathematics handouts is the availability of materials in accordance with the demands of the curriculum, target characteristics, and the demands of solving learning problems.…”

Problem solving ability is a very important to attainment of objectives mathematics learning. In fact, the problem solving ability of student is still low. One of the efforts to improve the problem solving ability is handout development on contextual based-approach. The purpose of this development research is to know the characteristics handout on contextual based-approach which are valid, practical, and effective. This development research uses a Plomp model consisting of three phases namely : preliminary, prototyping, and assessment. The instruments were used in this study are validation sheets for RPP and handout, questionnaire for teacher and students, sheets of observation, and test. Handout on contextual based-approach has been valid with validity was 3.58 and it was practical with practicality level of the according to the teachers' response gave 87,86% and students' response was 82.73%. They also efective to improve the problem solving ability of student.

“…In line with (Kawiyah, 2015), it is shown that the development of scientific-based mathematics learning tools to improve student learning outcomes is considered effective for use with the percentage of students achieving KKM of more than 75%. Research also shows that the results of effectiveness testing on learning tools to improve student learning outcomes are considered effective with completeness of student learning outcomes of 75% (Simanungkalit, 2016). The researcher then conducted an average difference test to see the difference in the ability to solve mathematical problems of the experimental class and the control class.…”

This research is motivated by the lack of optimal learning outcomes of students due to the lack of learning devices that are considered being able to train students’ abilities in solving problems. The purpose of this study is to develop mathematics learning tools that meet the validity, practicality, and effectiveness requirements to improve the learning outcomes of grade VIII students of SMP / MTs on material number patterns. The development model used is the ADDIE model for designing learning systems. The instruments used were syllabus validation instruments, RPP, LKPD, practicality instruments and effectiveness instruments. The technique used is the technique of collecting observation data, interviews, questionnaire documentation and tests. Mathematics learning to use the MASTER Plan technique based on a scientific approach is already valid with the results of syllabus validation 84.25%, RPP 90.30%, LKPD 86.50%. This learning device fulfills the practical requirements for large group trials with an average of 93.52% results and an average student questionnaire response rate of 95.66%. The use of effective learning tools to improve student learning outcomes for KKM achievement is 83.33%.
