This study aims to find out "the effectiveness of guided discovery models by using super-task tasks on the development of students' mathematical problem solving abilities". This research is designed by using posttest only control which the research subject is first year students of 2018/2019 academic year. This research uses saturated sampling technique because all members of the population are used as samples. Data collection techniques in this study only use test instruments. Data analysis technique was done by using t-test. The results of the data analysis obtained that hypothesis testing in the experimental and control class obtained t calculation  = 3.41 with t table = 1.67. Because t calculation > t table then H0 is rejected so that it can be concluded that the guided discovery learning model by using superchemical tasks is more effective than the direct learning model on mathematical problem-solving abilities of first-level students in school mathematics II even semester at IKIP PGRI Bojonegoro.   Penelitian ini bertujuan untuk mengetahui “efektivitas  model penemuan terbimbing dengan menggunakan tugas superitem terhadap pengembangan kemampuan pemecahan masalah matematika mahasiswa”. Penelitian ini merupakan penelitian dengan desain yang digunakan adalah posttest only control  dimana subyek penelitiannya adalah mahasiswa tingkat I tahun ajaran 2018/2019. Penelitian ini menggunakan teknik sampling jenuh karena semua anggota populasi dijadikan sebagai sampel. Teknik pengumpulan data dalam penelitian ini hanya menggunakan instrument tes. Teknik analisis data menggunakan uji–t. Hasil dari analisis data diperoleh uji hipotesis pada kelas eksperimen dan kontrol diperoleh thitung= 3,41 dengan ttabel = 1,67. Karena   thitung > ttabel maka H0 ditolak sehingga dapat disimpulkan bahwa model pembelajaran penemuan terbimbing dengan menggunakan tugas superitem lebih efektif  dibandingkan dengan model pembelajaran langsung terhadap kemampuan pemecahan masalah matematika mahasiswa tingkat I pada mata kuliah matematika sekolah II semester genap di IKIP PGRI Bojonegoro.

This type of research is a quasi experiment with the posttest only design with a nonequivalent group. The population in this study were 7th grade students of SMPN 1 Mataram in the academic year of 2019/2020. Sample determination using purposive sampling technique, where the sample of this study is students of class VII-I as an experimental class and students of class VII-H as a control class. In the experimental class applied the TAPPS learning model and control class applied the direct learning model. The instrument used in this study was a test of mathematical problem-solving abilities (posttest) on algebra form material. Quantitative data analysis was performed using t-test. The results of the data analysis showed that there are significant differences in students' mathematical problem solving abilities between the classes that get the TAPPS learning and direct learning. This suggests that learning with the Thinking Aloud Pair Problem Solving (TAPPS) model affects the ability to solve mathematical problems in the form of algebra material.

This study aims to determine the effect of the use of the super-scaled model of scaffolding on students' mathematical problem solving abilities. The sampling technique used was cluster random sampling with 3 classes namely experimental class 1 (the class was treated with scaffolding assisted superememe learning model), experimental class 2 (superitem learning only) and control class (the conventional treatment class). Hypothesis testing used is anava 1 cell path is not the same. The results of the study found that there were differences in students' mathematical problem solving abilities by using learning models of scaffolding assisted supermarkets. Furthermore, the mathematical problem solving ability of students with the super-intensive learning model assisted by scaffholding is the same as the mathematical problem-solving ability of students using superemit learning models. The mathematical problem solving ability of students with superficial learning models assisted by scaffholding is better than the students' mathematical problem-solving abilities using conventional learning models. Furthermore, the mathematical problem solving ability of students with superemit learning models is the same as the mathematical problem solving ability of students using conventional learning models.

Difficulties of primary school students in solving mathematical problems that require problem solving or reasoning abilities indicate the existence of problems in the process of learning mathematics, because one of the purposes of learning mathematics in primary school is to develop the students’ mathematical problem-solving skills. As a solution to overcome the problems, this research aims at understanding how the implementation of the guided discovery learning model influences mathematical problem-solving skills. This research employs a quasi-experimental design by involving all fifth-grade students at one of primary schools in Tebo Regency, Jambi. The simple random sample was conducted to obtain class VB as experimental class, and class VA as control class. Based on the results of the final score, experiential class obtained an average score of 86.00, and control class obtained an average score of 76.93.  The results of hypothesis test using t-test obtained tcount = 2,203 > ttable = 2,020, which indicated that H0 was rejected, and H1 was accepted. Therefore, the guided discovery learning model influenced the fifth-grade students’ mathematical problem-solving skills, thus it is recommended for teachers to be able to use the guided discovery learning model in the mathematics learning process.
