One of the main goals of school mathematics is the achievement of mathematical problem-solving abilities through problem-based learning. It is expected that these abilities can be achieved well by students. However, the complexity of the problem and minimum confidence become a problem when students experience complex situations created in the problem-based learning process. Scaffolding becomes essential because of the differences in each student's knowledge stored in long term memory. The purpose of the study was to analyze differences in mathematical problem-solving abilities with two different learning and based on initial mathematical abilities. Learning in the experimental class is problem-based learning with scaffolding, and then control class learning is problem-based without scaffolding. The research method used was a quasi-experimental design with a matching-only pretest-posttest control group design. Sample selection using purposive sampling to get samples with the same characteristics, the total number of samples is 60 students with each division 30. The initial mathematics ability has the same role in the mathematical problem-solving ability in the experimental and control classes. That is when students are in the high category then the ability of severe mathematical problem-solving. However, when the two classes are compared, the results are significantly different. Scaffolding becomes a factor that distinguishes the ability to solve mathematical problems.

The purpose of this study was to analyze the mathematical problem-solving ability and characters of students who were taught using problem-based learning and ordinary learning based on Islamic perspectives. The instrument used in this study was a test of problem-solving ability and a students’ character questionnaire. This research was a quasi-experimental research with pre-test and post-test control group design. The sample of this research was 84 students from Private Islamic School in Medan, North Sumatera, by using a purposive sampling technique. The data in this research was declared homogenous and normal after being tested using the Levene’s Test and Kolmogorov-Smirnov Test. The hypothesis analyzes used was the Two Way-ANOVA test assisted by SPSS 25. The result showed that there was an improvement in mathematical problem-solving ability and students' characters through problem-based learning based on Islamic perspectives. However, there was no interaction between students' gender and problem-solving ability and character improvement based on Islamic perspectives. The gender factor in problem-based learning was not related to students’ cognitive and affective aspects. Each student with any gender had difference characters, especially related to Islamic perspectives. This research-proven that problem-based learning model had an important role in teaching and learning, and it can be used to improve students' mathematical and character problem-solving ability.

This research was motivated by the low mathematical problem-solving ability of the seventh grade students of Al-Falah Islamic Junior High School Jambi. This research is a quasi-experimental study with Nonequivalent Pretest-Posttest Control Group Design design and a pattern that is all students of Al-Falah Islamic Middle School in the academic year 2017/2018. Sampling used purposive sampling, which is a sample consisting of three classes namely class VII.1, VII.2 and VII.4 where the given sample is different. The instruments used in this study are teaching materials and mathematical solution ability tests. The research data were analyzed using non parametric Kruskal Wallis H. statistical results. The results showed that there were differences faced by students who studied with two types of Two Stay-Two Stray (TS-TS), Problem Based Learning (PBL) learning models, and models conventional learning. After further using the Games-Howell test, the differences in the TS-TS class and PBL class then become PBL classes and Conventional classes.Keywords: Mathematical problem solving ability, Two stay-Two Stray (TS-TS), Problem Based Learning (PBL).

The Industrial Revolution 4.0 on Education in Indonesia affects school activities rapidly. Teachers are no longer educated in classrooms only, but they can also utilize technology to conduct distance learning. One interactive application that can be used as a form of question exercise is Quizizz. Therefore, this research aims to: first, examine the effectiveness of students' activities by using Quizizz on mathematical problem-solving skills; second, investigate the differences in the increase in students' ability to solve mathematical problems between the class with and without the Quizizz-aided learning method; third, describe the activities of students who used the Quizizz-aided drill learning method; and fourth, describe the students' responses in using Quizizz. The research was quasi-experiment with a pretest-posttest non-equivalent control group design. The participants in this study are 67 of Grade10 students divided into experimental and control classes. Data collection techniques used were tests for students' mathematical problem-solving skills and questionnaires. The instruments were validated using Pearson correlation, while the reliability was tested using Cronbach's Alpha. Then, the N-gain test was used to analyze the data. The results showed that there was an effect on students’ learning activities by using Quizizz on their problem-solving skills. Besides, there was a difference in the improvement of problem-solving skills between the class with and without Quizizz-aided. Furthermore, students’ activities in three meetings have increased. Moreover, students provided a positive response in learning using Quizizz. Thus, it can be concluded that Quizizz is effective in improving mathematical problem-solving skills.

The research was caused by the poor of mathematical problem solving ability of students. This research aimed to compare of mathematical problem solving between students who learned through problem based learning and scientific approach. The method was an experimental method with a pretest-posttest control group design involving two groups and random sampling. At the first and end of learning, the two classes are given a test. The population in this research were Madrasah Aliyah students in Cimahi, while the sample consisted of two randomly selected classes. One class  which was given problem based learning and other class was given a scientific approach. The instrument was a set of  5-item mathematical problem solving test description, then those were analyzed with descriptive and inferential statistics using the help of minitab 17 software. Based on the results of the research, the conclusion was  the improvement of  mathematical problem solving  of students using problem based learning was better than students who use a scientific approach.
