Abstract
Technological developments in this era are experiencing rapid progress. Especially in the field of science, everyone refers to education that will trend in the 21st century. Where education will become very modern with the help of many technologies to support student learning. The android-based application is nowdays used in order to engage students- understanding of science learning. In this work, we will propose a android learning application, named “E-Layer”, as interactive multimedia for learning science. This application discusses physical material on the topic of the earth layer. This application is made using Unity software. Unity is software that can make applications for games or learning applications in two dimensions or three dimensions that are packaged in an interactive multimedia display. Researchers have evaluated this device. The results showed that based on content expert evaluations, the average mobile learning score was 96%, language evaluation based on experts was 82.50%, and media design (IT) rated an average of 87.93% from the range 88 , 81%. As well as based reviews from science teachers and junior high school students the percentage of mobile learning applications is 90.55% and 92.50. Based on this, the Android mobile application is very suitable for use as a learning application. This application is dynamically designed and equipped with various supporting features, such as: images, videos, sounds, multi-language animation settings, and so on. The author suggests that this application can continue to be developed in future studies.

Abstract
One of the problems behind this research is the learning difficulties experienced by students on the structure of the repetition algorithm algorithm. Context problems (problems) that are not familiar or foreign to someone often make it difficult for them when trying to find the answer. Lack of mastery of basic concepts or lack of experience working on problems related to pseudecode, also influence the emergence of difficulties when working on the problem at hand. The emergence of difficulties in learning basic programming can also be caused by factors students who are less motivated in learning. Therefore, this study aims to develop a learning method using the Didactical Design Research (DDR) approach with multimedia assistance to help identify students difficulties and help find solutions. There are two stages in this study, namely the first one is to identify learning obstacles, and then is to build and implement interactive multimedia based on DDR to students. Based on the results of research and discussion it can be concluded that: 1) The form of interactive multimedia based on a didactic design containing the learning structure of the repetition algorithm “for”, “while do”, “do while” which is packaged in the form of interactive multimedia and contains questions and also stimulus that can guide students in understanding the structure of the repetition algorithm; 2) Almost all students show a positive attitude towards learning media by using interactive multimedia based on didactic designs. In the future, DDR will be developed for improving students- critical thinking.

Abstract
This research aims to study the influence of STEM-Integrated Learning Cycle 7E on students- creative thinking skills in the topic of temperature and heat using a quasi experimental research with Pre- and Posttest Design. The research subject is 66 grade XI students of MAN II Batu Indonesia. They are distributed in the experiment (n=30) and the control (n=36) classes and received, respectively, STEM-Integrated Learning Cycle 7E, and Learning Cycle 7E models. The research instrument is students- Creative Thinking Skills Test with 0.803 alpha Cronbach reliability. The data is analyzed using descriptive, t test, N-gain, and effect size. The result shows that the STEM approach can increase creative thinking skills as indicated by the significantly higher average skill score obtained by the experiment class. Beside that, both classes increase the skill from Almost Not Creative to Creative levels. Also, both classes increase it at a medium category. Furthermore, especially for fluency indicator, the experiment class obtains a high category. The practical implementation of STEM-Integrated Learning Cycle 7E model has a very large impact than Learning Cycle 7E class in increasing the students- creative thinking skills. The experiment class students give higher positive response than control class for learning process.

Abstract
This research is motivated by still have low ability of students mathematical understanding and lack of student independence in learning mathematics, to overcome these problems it is necessary to have an approach in learning. The alternative approach applied is the realistic mathematic educations approach. This study aims to determine and examine the mathematical understanding ability of junior high school students in one school in Cimahi. The research method used was experimental method in the form of pretest-posttest control group design. The population in this study were all seventh grade junior high school students in Cimahi, while the sample was seventh grade junior high school students in one of the Schools in Cimahi representing population characteristics. The data collection in this study uses a test type description and non-test that is a questionnaire. Then the data is processed using SPSS-16 and Microsoft Excel. Based on the results of the study it can be concluded that the mathematical understanding ability of junior high school students whose learning uses the Model-Eliciting Activities approach is better than that using conventional learning, student learning independence using realistic mathematic educations approache is better than those using conventional learning, and the implementation of learning using the Model approach -Electiting activities in the field are in accordance with the steps that make students more active in learning mathematics.

Abstract
This research departs from the application of the scientific approach in K13 which is expected to develop students HOTS abilities. With regard to that matter, various learning models that are in accordance with the scientific approach are implemented to have optimal impact. In line with this idea, the purpose of this study is to examine comprehensively the ability of VII grade students in solving contextual problem which are seen as one of the vehicles to build HOT abilities. The subject of this study was VII grade students in the school year 2018/2019 which numbered 356 people. The research data was collected by tests then analyzed descriptively and inferentially. The results of data analysis showed that: (1) students who were taught with K13-based learning models had the ability to solve contestual questions significantly better than students who were taught conventionally; (2) the ability of students who are taught to use the K13-based learning model in completing contextual questions is more complete compared to students who are taught conventionally.
