This research aimed to determine the effectiveness of the implementation of tsunami understanding media through Android-based physics mobile learning in improving students' problem-solving skills and natural disaster preparedness. This study employed quasi-experiment research with a non-equivalent control group design. This research subjects were fifty-six students of class XI IPA at SMA N 1 Kretek, Bantul, Yogyakarta. The sampling technique employed in this research was the simple random sampling technique to determine the experimental and control groups.  The research data had been obtained through pretest and posttest in the form of essay tests. The data obtained were then analyzed using N-gain. The analysis results were used to determine the effectiveness of the media using the Hotelling's Trace test in MANOVA test analysis. Normally distributed and homogeneous data are required to perform the multivariate analysis. The results showed that the tsunami understanding media through Android-based physics mobile learning improved students' problem-solving skills and natural disaster preparedness compared to the learning using PowerPoint presentation. The research decisions were based on the significant value that was smaller than 0.05 (0.0000.05), and the value of the Partial Eta Squared was 0.359 in the broad category.

Problem-solving is a process or thinking activity to solve a problem. Mathematical problem-solving skillis needed for students both in the process of understanding mathematics itself and in everyday life. The problem solving can beachieved by implementingthe learning using a problem-solving approachwhich trains students to deal with various problems including individuals and group problemsto be addressed individually or together. This learning is oriented towards the investigation and discovery which is solving the problems. It is the basis for students to solve problems critically, systematically, logically, and creatively as well as the ability to collaborateeffectively and to present fundamental knowledge which in turn can improvethe solving skill. This study aimed to examine whether the improvement of mathematical problem-solving skillof students learned with the problem-solving approach wasbetter than students taught using the conventional learning. The improvement was examined based on the students’ levels. This study applied a pre-test and post-test control group design. The population of the study was Year 7 students of one of the junior high schools in Pidie, Indonesia, consisting of seven classes in 2017/2018.Two classes, a control, and an experimental class were selected as the sample through purposive sampling technique. The instrument used to obtain the data is the mathematical problem-solving skill test.The data was then analyzed by employing a two-way ANOVA test using SPSS. The results of the study showed that the improvement of mathematical problem-solving skill of the students learning with the problem-solving approach is better than the students experiencing the conventional learning, reviewed based on student levels. There is no interaction between the learning models and student levels on mathematical problem-solving skills. The resultsare expected to be used as a reference for mathematics teachers to apply the problem-solving approach in the learning process to improve mathematical problem-solving skills.

This study aims to determine the improvement of problem-solving skills using problem-based digital learning module. The research method used is quasi-experiment design with non-equivalent control group design. The sampling technique used is the purposive sampling of 60 subjects with 30 for the experimental class and 30 for the control class. The research result indicates the learning process both classes runs well. It is proven by the significance of the hypothesis test result which is less than α (0,005) < 0,05). It can be concluded that Ha is accepted and Ho is rejected. It means that there are differences in students’ problem-solving skills in the experiment class and control class. This proves the treatment in the experimental class using problem-based digital learning module integrated with religious values can influence students' problem-solving skills better than the PowerPoint learning media used in the control class

The purposes of this research is to the differences in mathematical problem-solving skills enhancement and self-efficacy among students who had learned Realistic Mathematics Education (RME) approach and students who received conventional instructions. Reseach use quasi-experimental was used pre-test research design posttest control group design. The experimental group was treated using RME  approach while the control group gain use conventional approach. To gather the instrument is the form of mathematical problem solving ability test, and a questionnaire to determine students' self-efficacy toward mathematics. This research was conducted at Secondary Islamic School . The population is  grade VIII students MTsN Model Banda Aceh inl year 2012/2013. The samples were  two classes, VIII-7, class as the experimental class and the control class VIII-6, by purposive sampling technique. The researc found that studens mathematical problem-solving ability which were taken by with RME approach better than conventional approaches. Based on the analysis of self-efficacy RME class increases more than the self-efficacy of students who received conventional learning. Furthermore there a relationship between the ability of solving mathematical problems with self-efficacy of students in the experimental class and control with very low qualifications.

The purpose of this study was to obtain empirical evidence about the use of cooperative models of Team Games Tournament to increase the ability of students on solving problems with the summation material fractions. To achieve these objectives, the research carried out in the form of an experiment by comparing the problem solving ability of students to the material sum of fractions through the use cooperative model of TGT and students who received conventional learning. The design is a pretest-posttest control group design. The sampling technique used is purposive sampling technique. The instrument used is to use tests that pretest and posttest. The data were analyzed quantitatively for the results of the pretest, posttest, and normalized gain value. Based on data analysis in this study we concluded that there are differences in problem solving ability of students to the material sum of fractions through the use of cooperative models of Team Games Tournament with students who studied with conventional models, and improved problem solving abilities of students in the material that follows the fractional summation cooperative learning of TGT better than students who take the conventional learning model. Therefore, the ability of solving problems of students at grade material fractions summation cooperative modeled of TGT has increased quite good.

This study aim to determine the effect of Problem Based Learning (PBL) models in mind map integration to creativity of problem solving in the environmental pollution concept of graders X. The method used is a Quasi-experimental design form Nonequivalent Control Group Design (pretest- posttest). The study population is all the students of graders X academic year 2017/2018 as many as 9 classes with the number of 360 students. The sample used was 80 students from two classes as an experimental class and a control class. Sampling was done by Cluster Random Sampling technique. Instruments used include test descriptions, questionnaires and teacher observation sheets. The results of the analysis of the test descriptions creativity in problem solving obtained results of hypothesis testing (t test) i.e. 20.5 t count > t table of 2.66 means that Ho refused and Hi accepted, it means PBL learning models in Mind Map integration effect on creativity in problems solving. This is indicated by an increase in the average score on each indicator of creativity in problem solving in which students are able to grow various ideas, enrich ideas, add or detail the details of an idea and determine the truth to solve the problems. From the analysis of questionnaire data showed an interest in learning to use the PBL modela in Mind map integration, students agreed that if the model of PBL in Mind map integration may be easier to learn about the concept of Environmental Pollution. In addition, students also agreed that if the PBL models in Mind map integration effect on creativity in problems solving. The results showed that there was a significant influence between learning using PBL models in Mind map integration those not using the learning models to creativity in problems solving in the concept of environmental pollution of graders X.
