Development Of E-LKPD hots questions as a medium for learning mathematics on the material of the Phytagorean theorem

Learning in the modern era demands learning based on KBAT, literacy skills, character education, and 4C (critical, creative, collaborative, and collaborative), all of which can be achieved through the development of E-LKPD based on KBAT combined with critical thinking skills indicators. The purpose of this study is to produce an E-LKPD product using KBAT-based questions, to determine whether the KBAT-based E-LKPD is suitable for the material of the Pythagoras theorem, and to determine the student's reaction to the created KBAT-based E-LKPD. . This refers to the ADDIE model. This study involves eighth grade students of SMP N 2 Utara Province who are the subject of this study and the object of this study is E-LKPD using KBAT based questions. Student questionnaires and confirmation sheets were used in this study. This study obtained the results which are: (1) The feasibility of E-LKPD using KBAT-based questions by media experts is in the feasible category (80.00) and material experts are also in the feasible category (77.5); and (2) Student response to E-LKPD using KBAT-based questions is in the good category with an average of 81.1%. Thus, this study shows that E-LKPD using KBAT-based questions can be used as media in the learning and teaching process

Increasing Junior High School Students' Mathematical Comprehension with Realistic Mathematics Education (RME) Approach

Mathematical understanding is an important basis for thinking whensolving mathematical problems. Mathematical understanding is also the basis ofthinking in learning mathematics to find out the results of mastery learning. Thiscan be seen in the results of the test scores of students with mathematicalunderstanding abilities that are still below the level of mastery learning, thereforethe importance of mathematical understanding abilities is increased by using theRealistic Mathematical Education (RME) learning approach. This study uses mixedmethods where the research strategy combines qualitative and quantitative methodssimultaneously. The results of the research conducted the average score was stilllow, namely 62.5% below the average and 37.5% above the average, but afterapplying the RME learning method, it showed that the average student scoreincreased to 21.9 % below average and 78.1% above average. Based on the resultsbefore and after the test, students' mathematical understanding ability increased by40.6% after applying the RME teaching method, thus proving that RME had apositive effect on increasing mathematical understanding

Problem-based learning model implementation to improve students problem-solving skills

This research aims to improve students' problem-solving skills about additives in food and beverages. This study used one group pretest and posttest design. This study involved thirty-one students from grade 8 at one of the state junior high schools in Gresik Regency, East Java, for the 2021/2022 Academic Year. Data collection techniques using observation assessment sheets, written test assessment sheets, and response questionnaire forms. Based on this study, the results of the percentage of learning implementation of the first meeting of the first session were 91%, the first meeting of the second session was 94%, the second meeting of the first session was 92%, and the second meeting of the second session was 95% by meeting the excellent category. The problem-solving skills were obtained n-gain 0.78 high categories, including the stage of formulating the question 0.67 medium categories, the hypothesis  0.57 with the medium category, determining the solution obtained 0.83 with the high category. The calculation of n-gain in each stage obtained an average n-gain of 0.74 by fulfilling the high category—the response questionnaire form from students with a percentage with excellent categories and positive student responses. The results of this study show that implementing problem-based learning can improve problem-solving skills, especially additives in food and beverages

The Application of Synchronous and Asynchronous Learning using E-learning on Elementary Linear Algebra

Learning activities were changed from face-to-face to full-online due to the COVID-19 pandemic at the end of 2019. Online learning through WhatsApp Group (WAG) was used by a mathematics teacher in higher education program in the early 2020. However, the learning result showed that 75% of preservice teacher were unable to accomplish their elementary linear algebra material. The combination of online learning through asynchronous method and synchronous learning was an alternative solution to solve the problem and enable preservice teachers having virtual face-to-face interactions with their lecturers. Therefore, this study was conducted to determine the improvement in preservice teachers' learning outcomes and responses to synchronous and asynchronous learning. The research design used was one group posttest-only with 23 subjects were selected by clustered random sampling. Data were analyzed by descriptive statistical analysis. The test results showed that learning outcomes after synchronous and asynchronous learning was effective. While the questionnaire results expressed most preservice teachers gave a positive response to both learning methods. Thus, the combination of the two methods could improve the effectiveness of online learning during the Covid-19 pandemic. It is recommended that higher education institutions provide innovative e-learning platforms for preservice teachers in developing further online learning methods

Development of Augmented Reality Media Based On Cybernetic Learning Theory to Stimulate Spatial Abilities

Hearing impairment students have limited vocabulary and have difficulty understanding abstract terms, which affects learning the concept of a plane solid figure that they know at school. Deaf students tend to have difficulty perceiving objects from a certain point of view and understanding the relationship between these objects in a particular space. These difficulties affect students' spatial abilities and require special handling in the form of learning-oriented to the learning process, not learning outcomes. The learning process itself can be determined by information systems such as the basis of cybernetic theory and supported by information technology-based interactive learning media. Therefore, this study aims to develop augmented reality media based on cybernetic learning theory to stimulate valid and practical spatial abilities of deaf students. The research and development model carried out in this study is the Borg and Gall model, which has systematic and descriptive steps for practical problems in teaching through applied research. Researchers collected data through validation questionnaires and student response questionnaires. Data analysis was carried out qualitatively and quantitatively. The augmented reality media developed here can be said to meet the criteria of validity and practicality based on the results of the product feasibility test. This media has also proven to be a solution in helping teachers to stimulate the spatial abilities of deaf students through a meaningful learning process determined by a technology-assisted information syste
