This research aims to improve senior high school students’ physics problem-solving skills through learning used IBMR learning model. This research was a pre-an experimental study with a one-group pre-test and post-test design. The Methods of data collection used validation and test. The materials used to teach were valid category by two experts and can be used to practice physics problem-solving skills. The average post-test score physics problem-solving ability was 73.24 with an N-gain of 0.59 was classified as moderate. The success of IBMR learning model-based devices in practicing problem-solving abilities can be seen in the increase in the average score in each indicator of problem-solving abilities. The indicator of understanding the problem had the highest post-test average score of 94.58 with an N-gain of 0.89 in the high category. The problem-solving indicator had the lowest posttest average score was 58.22 with N-gain 0.39 and mean that it was the moderate category. Based on the results study, it can be concluded that the learning used by IBMR learning model can practice the ability to solve physics problems on heat material and its displacement. Learning with the IBMR learning model was expected to train students in solving physics problems. The stages in the IBMR learning model can help students

In this research, a study is made of the effect of the application of Pólya's problem-solving heuristic on the development of geometric skills and its impact on academic performance. In the intervention, the topic of angles was developed, to a section of 25 fourth grade high school students in an educational center in the Municipality of Yamasá of the Monte Plata Province in the Dominican Republic. A quasi-experimental type design with a quantitative approach and correlational scope was used, with a non-probabilistic sample, with an intact group and a pre-test and post-test design. The results show that, through Pólya's problem-solving heuristic, students expanded their skills in geometry that greatly increased learning about angles. Corroborated by a growth in the average of the grades from 62.4% that was obtained in the pre-test, to 83.7% that was reached in the post-test, showing statistically that there are significant differences. It stands out that the Pólya heuristic was highly valued by the students under study, therefore, it is believed that it had a positive influence on the benefit of their learning about angles. In addition, the results of the post-test reveal that there is no relationship between the sex of the group under study and the scores obtained when the Pólya heuristic is applied.

This literature study aims to obtain the thinking process profile of senior high school students in physics problem-solving based on differences in emotional intelligence levels and gender. In this study used literature study method with phenomenological analysis, functionalism analysis, and critical analysis. The sources used to compile this article include some literature on emotional intelligence, gender effect, thinking process, problem-solving, and several empirical study on students in physics problem-solving, especially in senior high school. The authors summed up the conclusions based on the results of the literature study as follows: (1) The profile of the thinking process is influenced by emotional intelligence level and gender; (2) Emotional intelligence is directly proportional to the thinking process of students in the process of solving physics problems; (3) Students who have high emotional intelligence are more likely to have high physics problem-solving skills; (4) Gender differences (male and female) in solving physics problems, generally, are still debatable, in which sense is it better? Then it further research needs that is valid and reliable to answer this question. (5) There is a strong tendency that the male gender is more resilient in dealing with and solving complex physics problems; (6) The gender of female students is superior in solving physics problems that require very high detail. The main implication of this article is to obtain the thinking process profile of senior high school students in physics problem-solving based on terms of differences in emotional intelligence levels and gender.
