The method in this study was qualitative with phenomenological approach. Six students of grade XI in a senior high school in Banda Aceh City were selected as the subject. The data were collected through a test consisting of mathematical reflective thinking skills problems, interviews, and documentation. The indicators of mathematical reflective thinking skills include identifying problems, interpreting problems, evaluating problems, predicting problem-solving, and drawing conclusions. The results show that there are students who have not been able to identify problems clearly and correctly, all students have not been able to interpret the integral-related problems clearly and correctly, some students have not been able to evaluate the integral-related problems clearly and correctly, some students have not been able to predict the integral-related problems clearly and correctly, and some students have not been able to draw conclusions regarding the integral-related problems clearly and correctly.

Research paper thumbnail of A Meta-Analysis on The Effect of Inquiry Learning Model on Students’ Mathematical Problem-Solving Skills

This study examines the effect of the inquiry learning model on the mathematical problem solving ... more This study examines the effect of the inquiry learning model on the mathematical problem solving ability of students in Indonesia through meta-analysis. This study analyzed seven primary studies that met the inclusion criteria. The effect size index was calculated using the Hedges g equation and statistical analysis using comprehensive meta-analysis (CMA) software. Effect size testing is done by analyzing four characteristics, namely class of study, year of study, and sample size. Based on the results of the analysis using CMA, the inquiry learning model has a moderate effect (0.652) on the overall mathematical problem-solving skills of students. The use of the inquiry learning model is more effectively used in 8th-grade, in the range of 2015-2017 and 2018-2020, the sample size is less than or equal to 30. Thus, it can be seen that the inquiry learning model is useful in improving mathematical problem-solving skills.

They make material a measure of success and happiness. As a result, people often lose control. The more visible humans justify any means to achieve goals. In fact, true happiness and peace of mind cannot be obtained from material, position, long life and freedom. For those who do not find happiness and peace of mind with their glamor, the world seeks tranquility or happiness in its soul by reciting and following the tarekat. The practicing people believe, feel, and declare that through the practice of the teachings and practices of the tarekat this inner peace and essential happiness can be achieved. Of course, this was achieved not apart from the role of murshid who consistently guided and nurtured the spiritual practitioners through their practices and teachings. This means that spiritual education in the form of internalizing religious spiritual values ​​instilled by the murshid to the pr...
