<p>The present study aimed to identify the effect of mental computation in improving the ability of university undergraduates in mathematical problem - solving. To achieve this aim, the quasi - experimental approach was used. Participants were (80) preparatory year students at Najran University in Saudi Arabia who were distributed into two main groups using the simple random sampling. One of these groups (N = 40) was assigned as the experimental group and was taught via the use of mental computation method. The second group (N = 40) was assigned as the control group and studied through the use of traditional methods. Mathematical problem - solving ability pre-test and posttest were applied to both groups. Findings showed that there were statistically significant differences between the two groups with regard to the mathematical problem- solving posttest in favor of the experimental group.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0994/a.php" alt="Hit counter" /></p>

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.

AbstrakPentingnya kemampuan pemecahan masalah dalam pembelajaran matematika belum diikuti dengan pencapaian yang baik. Penelitian ini bertujuan menerapkan model pembelajaran Problem Solving dan Problem Posing serta menguji ada tidaknya perbedaan kemampuan pemecahan masalah dari kedua model tersebut. Penelitian dilaksanakan pada kelas X salah satu SMA Negeri di Salatiga dengan materi trigonometri. Sampel sebanyak 53 siswa, terbagi dalam dua kelompok eksperimen. Penelitian ekperimen semu ini menggunakan desain randomaized control group pretest-postest design, dengan instrumen berbentuk tes kemampuan pemecahan masalah dan lembar observasi. Analisis data menggunakan kovariansi pada taraf signifikan 𝛼 = 5% dengan kemampuan awal sebagai variabel kovarian. Hasil uji hipotesis menyimpulkan bahwa dengan mengontrol kemampuan awal siswa didapat bahwa siswa yang melaksanakan model pembelajaran Problem Posing secara signifikan memiliki kemampuan pemecahan masalah matematika yang lebih baik dibandingkan siswa yang melaksanakan model pembelajaran Problem Solving. Hasil ini menunjukkan pembelajaran hendaknya tidak hanya melatih siswa menyelesaikan masalah tetapi juga mengkonstruksi permasalahan. Differences in problem-solving abilities from the application of problem-solving and problem-posing in high school studentsAbstractThe importance of problem-solving abilities in mathematics learning has not been automatically followed by good achievement. This study aims to apply Problem Solving and Problem Posing learning models and to test whether there are differences in the problem-solving abilities of the two learning models. This research was conducted in class X mathematics learning at one of the public high schools in Salatiga on Trigonometry material. This quasi-experimental study used a randomized control group pretest-posttest design, with instruments in the form of problem-solving ability tests and observation sheets. The data analysis used was the covariance test at the significant level α = 5% with the initial ability as a covariate variable. The results of hypothesis testing with covariance analysis concluded that by controlling students' initial abilities it was found that there were significant differences in mathematical problem-solving abilities between the application of the two models. Students who carry out the Problem Posing learning model significantly have better mathematical problem-solving abilities than students who carry out the Problem-Solving learning model. These results indicate that learning should not only train students to solve problems but also construct problems.

This study examined the impact of a program based on problem-solving in mathematical problem-solving among 10th grade students. The sample of this study consisted of (89) male and female students; Wadi Bani Kharous Basic Education School and Om Hakeem Basic Education School located in AlBatina South Governorate (Oman). The study followed the quasi-experimental research design with experimental group consisted of (48) students, and control group consisted of (41) students. The instructional materials of Polynomial and Algebraic Functions Unit and Trigonometric Functions Unit for Grade 10th were designed according to a program based on problem-solving. The problemsolving test was valid and reliable. The findings indicated that there were significant statistical differences in mathematical problem-solving test between the experimental and control group due to teaching method in favor of experimental group. The findings indicated that there were no significant statistical differences in mathematical problemsolving test between male and female students. The findings also indicated that there were statistical significance differences in mathematical problem-solving test due to the interaction between and teaching method and gender. The study recommended organizing training workshops for mathematics teachers to introduce programs based on problem solving, training them to build educational programs based on problem solving, and urging them to adopt it due to the positive impact it has shown in teaching mathematics.

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.
