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:Â 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.Â 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 studentsâ€™ 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, studentsâ€™ 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.

Multiplication is the most difficult basic arithmetic operation and has been documented since 1980. Another multiplication difficulty dealing with story problems, they tend to assume that multiplication produces a larger result and the other way for division. Several studies show basic mathematics as one of the cognitive factors that affect the financial literacy ability of each individual. This study used a qualitative descriptive analysis with the subject of three students from different schools and geographical locations. Basic mathematics as one of the cognitive factors that affect the financial literacy ability of each individual The introduction of cases such as ordering through online applications in learning mathematics may improve students' knowledge about activities related to finance. Individual context is important in personal financial management since the decision pertains to the fulfilment of personal needs.

This study aims to enhance students' mathematical problem-solving skills through the implementation of the Problem-Based Learning (PBL) model in the topic of quadratic equations. The research was conducted using the Classroom Action Research (CAR) method based on the Kemmis and McTaggart spiral model, consisting of two cycles with the stages of planning, action, observation, and reflection. The participants were 18 eleventh-grade students from a vocational high school (SMK) in Sleman. The findings revealed a significant improvement in students' mathematical problem-solving abilities, with the average score increasing from 75 in Cycle I to 84.72 in Cycle II. The PBL model proved effective in enhancing problem-solving skills. Challenges encountered during Cycle I, such as students' difficulties in understanding problems and lack of participation in group activities, were successfully addressed in Cycle II through improvements, including clearer visualizations in the Student Worksheets and more heterogeneous group arrangements. This study concludes that PBL is an effective teaching model for fostering meaningful learning and improving students' learning outcomes in the topic of quadratic equations.
