Distance learning using information and communication technology brings some problems for some teachers in Indonesia, including the writer. Students learn independently without explanation from the teacher. This condition causes learning boredom for some students. SiJaPin (Sinau bareng Jateng Pintar) or Learning with Smart Central Java is an effort to overcome students boredom of Mathematics distance learning in Class VIIA SMP Negeri 12 Semarang . The implementation of SiJaPin is 1) Design and preparation stage 2) Implementation stage. The results of SiJaPin implementation are results of learning final evaluation, on the first day of learning, class VIIA students get an average score of 71.75 and 83.25 on the second day. Questionnaire of students' reflection on distance learning with SiJaPin: 18 students stated that they felt happy, 21 said they could overcome their boredom, and 10 said that they were motivated to learn. Supporting factors for the implementation of SiJaPin are the support from fellow teachers and principal, the enthusiasm of students, adequate facilities by the provided rooms, laptops, handphones and internet. Inhibiting factors for the implementation of SiJaPin 1) limitation of the teacher in monitoring internet signal, that makes students cannot hear teacher’s voice when starting the lessons, 2) the teacher is less careful that makes typing errors on the PPT slides, 3) lack of coordination on the previous days, 4) next lesson plan by video conference using attractive PPT.

This study aims to produce interactive multimedia based on scientific approach on plane shape material for the fourth grade elementary school students. This is a research and development using a 4-D model consisting of 4 stages, namely: defining, designing, developing, and disseminating. This research data collection technique is based on the results of the assessment by three experts, namely: expert on material, expert on media, and linguists. The expert's assessment shows that interactive multimedia meets the eligibility criteria. At the product feasibility test stage in a small group consisting of nine students, it was found that interactive multimedia met the eligibility criteria with an average score of 3.01 with a maximum score of 4.0. Based on the results of the study, it can be concluded that the interactive multimedia design based on the scientific approach developed in this study is proven to be feasible and can be used for fourth grade elementary school students.

This research is motivated by the real condition that students do not understand the concept of linear equations and one variable linear inequality and the teacher tries to improve understanding of these concepts. An alternative to solve this problem is by applying experiences, language, pictures, symbols, application (ELPSA) learning model using sticky tape media. This study aims to improve students' understanding of concepts in the subject matter of linear equations and inequalities with one variable in junior high school mathematics. Research subjects, students of SMPN Bulo Odd Semester 2018/2019 Academic Year class VII A consisted of 27 people. Methods of data collection, observation, tests, questionnaires and field notes. The implementation is carried out in 3 cycles, each cycle consisting of planning, implementing, observing, and reflecting. The data analysis technique was carried out in a descriptive qualitative manner. Descriptive analysis, to describe the implementation of the learning model and calculate the percentage of students who completed. Qualitative analysis using flow methods, namely data reduction, and drawing conclusions or verification. Conclusion (1) Learning with the ELPSA model with stick tape media can improve the concept of linear equations and inequalities of one variable in students of SMPN Bulo class VII A. (2) The ELPSA learning model with stick tape media can improve learning outcomes of linear equations and inequalities of one student variable SMPN Bulo class VII A.

Abstract. The industrial revolution 4.0 gave birth to an education era 4.0 which demands the use of cyber technology in the learning process, so that output matches the needs and demands of the times. The existence of abstract concepts and difficulty imagining spatial aspects become obstacles for students of class XII MIPA at SMAN 4 Kota Tangerang in learning to paint slices of space. Therefore, it takes the development of learning media that is able to help students learn it easily but is packaged in an interesting, exciting, fun way and in accordance with the direction of education 4.0. This research is a development research that aims to develop and determine the feasibility of multimedia e-learning based on Screencast O Matic and Powerpoint assisted by Geogebra and Kahoot in learning geometry for XII MIPA of  SMAN 4 Kota Tangerang students . Using the Four-D development model which includes the define, design, develop, and disseminate stages, the developer does not do the dissemination stage because what is done is only a product feasibility test. At the develop stage, an expert assessment was carried out consisting of an assessment of aspects of the content, media, language, and teacher / practitioner assessment and finally a development test. Based on the expert's assessment, the average score for the content aspect is 4.52 (Very Feasible), the media aspect is 4.22 (Very Appropriate), and the language aspect is 4.23 (Very Feasible). Based on the students' responses to the development test, it was obtained that the material aspects were 4.29 (very feasible), the media aspects were 4.11 (feasible), and the language aspects were 4.1 (feasible).

The implementation of distance learning can not be separated from various problems, including students who are lack of motivation, teachers who find difficulties to work together with parents, and teachers who find difficulties to develop ideas on technology-based learning. To overcome these problems, the student activity sheet which equipped with practice questions and assessments with Geogebra Book aid is already developed as a learning innovation. The material developed in this research is trigonometry with the sub material of graph of trigonometric functions. The research model which used is ADDIE (Analysis, Design, Development, Implement, Evaluate). The research was conducted in SMA Negeri 1 Kepanjen by involving 10 students of social class grade X as test subjects, consisting of 3 students with low ability, 4 students with moderate ability, and 3 students with high ability. Data analysis was measured based on aspects of validity and practicality. Calculation of research data shows that the research product is valid based on an average validity score of 93% and practical based on an average practicality score of 84%. Based on the results of this data analysis, it can be concluded that the product development of student activity sheet along with practice questions and assessments meets the valid and practical criteria to facilitate students and teachers in the process of learning activities.
