Cahyan Syari, Lisa Dwi Afri — Wed, 05 Feb 2025 00:00:00 +0000

This research aims to find out whether there is an influence and how the ability to use the photomath application has on students' mathematical problem solving abilities. This research is a quantitative research carried out at DWI SATYA Middle School with a pretest-posttest only one group design. The sample for this research was taken using a total sampling method of 15 students. This research instrument is a test of problem solving abilities in the form of a pretest and posttest. Furthermore, this research data was analyzed using a paired sample t-test after analyzing descriptive statistics and inferential statistics, namely the normality test and homogeneity test. The research results showed that the average pretest score for students who studied using the Photomath application was 36 and the posttest was 66 from the ideal score of 75. There was an increase of 30, which means there was an influence of using the Photomath application on students' mathematics learning with an N Gain score of 0.78 in the high category. Simultaneously, there is a significant influence of learning using the photomath application on students' mathematical problem solving abilities where a sig value of 0.000 is obtained which is smaller than the significance level of 0.05.

This study aims to describe the problem-solving profiles of eighth-grade students in the fraction material at SMPN Model Terpadu Madani, based on adversity quotient. The subjects of this study consist of 3 students selected based on the results of the ARP questionnaire and the recommendation of the mathematics teacher. The results of this study show that: (1) The problem-solving profile of students in the climber category can understand the problem by stating what is unknown and what data is given. However, they are less complete in writing down the known data from the problem, designing a well-structured solution plan, carrying out the plan as initially created, answering correctly, and checking their answer using a different method. (2) The problem-solving profile of students in the camper category can understand the problem by determining what is unknown and identifying the given data, designing a good and complete solution plan, carrying out the plan as initially made, and answering correctly, but they do not check their answer afterward. (3) The problem-solving profile of students in the quitter category can understand the problem by stating what is unknown and what data is given. However, they are less complete in writing down the known data from the problem, designing a good and complete solution plan, failing to implement the plan as initially made, not answering correctly, and not checking their answer afterward. In conclusion, there are 3 categories of students that require different treatment and attention from the teacher. Climber students need more attention in writing down the known data and checking their answer using a different method. Camper students need to be encouraged to check their answer after completing the problem, and quitter students require more intensive guidance in understanding the problem and carrying out the solution plan correctly.

This study aims to describe student problem solving based on the level of student learning independence. The method used is qualitative descriptive research. The subjects of the study were three students of grade IX D SMPN 7 Palu, who were selected using a learning independence questionnaire, with high, medium, and low categories. The problem-solving indicators used are indicators developed by polya, namely, understanding the problem, making a problem-solving plan, implementing the problem-solving plan, and re-checking. The results showed that subjects with high and medium independence were better at meeting each problem-solving indicator compared to low subjects. So it can be concluded that the higher the learning independence of students, the better the problem solving will be.

This study aims to describe the literacy and numeracy abilities of class VIII students at SMPN 02 Darmpelas in terms of low, medium and high mathematics anxiety. The method used is a qualitative descriptive method with instruments in the form of mathematics anxiety questionnaires, tests and interviews. The results showed that subjects who had low math anxiety were able to meet 3 numeracy literacy indicators, subjects who had moderate math anxiety were able to meet 2 of the 3 numeracy literacy indicators, and subjects who had high math anxiety were only able to meet 1 of the 3 numeracy literacy indicators. In conclusion, for the category of students with moderate mathematics anxiety, attention needs to be paid to writing down known and asked data in detail and clearly, while for students with high mathematics anxiety, students need intensive guidance from the teacher to understand the methods used in planning problem solving and also in drawing conclusions to obtain correct and appropriate answers.

This study aims to improve student learning outcomes through the TGT type cooperative learning model assisted by Quizizz. This research was carried out as many as II cycles, by following the predetermined stages. This research method leads to the steps of classroom action research (PTK) with a qualitative approach. The results showed that from cycle I to cycle II showed an increase in student learning completeness in learning addition & subtraction operations for numbers using the TGT type cooperative learning model assisted by Quizizz, namely in cycle I by 40% and in cycle II by 78%. Given the determination of the success indicator has been achieved in cycle II with an average student score of 78%, learning mathematics using the TGT type cooperative learning model assisted by quizizz can be declared successful. Based on the results of the study, it can be concluded that the application of the Team Games Tournament (TGT) type cooperative learning model assisted by the quizizz application can improve students' mathematics learning outcomes.

This research aims to obtain students' mathematical reasoning abilities in solving sequence and arithmetic series word problems in terms of learning style. The method used is providing learning styles, written tests, interviews. The results of this research show that of the three visual, auditory and kinesthetic subjects the ones with the best mathematical reasoning abilities are the visual and kinesthetic learning style subjects. In conclusion, the mathematical reasoning ability of visual subjects is able to fulfill four indicators, namely representing ideas, determining solution strategies, implementing solution strategies, realizing solutions and interesting conclusions. The auditory subject's mathematical reasoning ability is able to fulfill four indicators, namely representing ideas, determining a solution strategy, implementing a solution strategy, solving a solution and drawing conclusions, but in the process there are errors so that the results obtained are less precise. Meanwhile, the mathematical reasoning ability of kinesthetic subjects is able to fulfill 3 indicators, namely representing ideas, determining completion strategies and implementing completion strategies. It's just that when drawing conclusions, kinesthetic subjects are unable to write down their conclusions.

ABSTRACT

This study aims to determine the effect of problem-based learning on students' creative thinking skills in understanding linear equations. The method used is quantitative research with an experimental approach and descriptive analysis. The population consists of all seventh-grade students at SMPN 17 Bengkulu Utara, with a sample divided into two groups: VIIA as the experimental group with 22 students and VIIB as the control group with 23 students. Data analysis was conducted using SPSS 22, including normality tests, homogeneity tests, and t-tests. The results show a significant difference between the experimental and control groups, with a significance level (sig. (2-tailed)) of 0.000 < 0.05. Therefore, the alternative hypothesis (H₁) is accepted. After implementing problem-based learning, students in the experimental group demonstrated better creative thinking skills than those in the control group. In conclusion, problem-based learning positively influences students' creative thinking skills in understanding linear equations.
