Abstract

The acceleration of 4.0 industrial revolution caused the development of digital era developed rapidly, therefore, learning resources can be accessed everwhere and everytime. Since the learning sources are easy to find,  the teachers are required to change the learning pattern into a learning facilitator that the focus is to give the appropriate learning resources for students based on their needs. According to the results of the interviews, there is a learning problem shows that the student learning outcomes in the excretion system material for class VIII SMP in SMPN 1 Taman Sidoarjo is still low. For this reason, it is necessary to develop a mobile learning media material excretion system that is feasibly and effectively used by students of VIII graders at SMPN 1 Taman Sidoarjo. The development model used is R&D Models from Walter Dick and Lou Carey.The data collection methods used were from questionnaire and test. Based on the trial results and data analysis, there are several conclusions, the results of the feasibility test of mobile learning media from the experts of material and media obtained a very good category.The individual trial obtained an excellent category, which is 90%, the percentgage of small group trials  is 90% and categorized as excellent, whereas the percentahe of the field trials is 89% and included in the excellent category. It can be concluded that the mobile learning media is suitable to use in the learning process. While the t-test with db = N - 1 = 33 - 1 = 32 and a significant level is 5%. Then the value of t table = 2.037 and tcount is 5.49. T arithmetic <t table (5.49> 2,037), therefore, the headway of media has been effective in improving student learning outcomes in class X of SMAN 1 Taman Sidoarjo on excretion system material.

Abstract

The background of this study by the achievement of cognitive development in this case the introduction of the concept of numbers has not been achieved. Problems that exist in group A Christian kindergarten LOGOS, when spelling out there are still children who haven't spelled out exactly, there are objects that are missed when spelling out and have not been able to show many objects in accordance with the symbol numbers, especially numbers 5, 6, 7, 8, 9, 10, this happens because there is no media in accordance with the theme of the lesson (land animals) and the method used is still in the form of assignments. The purpose of this study is to describe the increase in children's ability to recognize the concept of numbers through the use of graphic media and three-stage learning methods in the learning process. This study uses a class action research (CAR) method which is carried out in two cycles. Each cycle consists of four stages, namely the planning stage, the implementation phase, the observation and reflection stage. The subjects of the study were children of Group A Christian LOGOS Kindergarten consisting of 17 children. Data collection techniques in this study through observation and documentation. The results of the first cycle and second cycle of research showed an increase. The results showed that the use of graphic media and three-stage learning methods can improve the ability of children to recognize the concept of numbers, especially the numbers 5, 6, 7, 8, 9, 10 in group A children of Christian Kindergarten LOGOS.

Abstract

The study aims to develop and validate open-ended mathematics questions, where measuring students' abilities at the field test stage is part of the final validation process to show that the instrument is functional. The development model with Tessmer's formative evaluation approach includes self-evaluation, expert review, one-to-one, small group, and field tests. The participants included one lecturer, two mathematics teachers, and students from grade IX. Individual trials involved three students, small group trials 12 students, and field trials 40 students. The data obtained came from quantitative and qualitative data. The instruments used included observation sheets, interviews, questionnaires, and tests. Analysis for quantitative data was carried out using the SPSS application. The findings of the study indicate that (1) this study produces a mathematics question product with an open-ended approach of 5 descriptive questions. Content validity (90.33%), construct validity (94.25%), and language validity (92.25%). High validity is caused by the formulation of questions that explicitly ask students to provide various ways, which directly target indicators of fluency and flexibility in creative thinking. In addition, the validity of each question item in the small group, namely r count > r table (0.576), with a reliability value of 0.931. (2) Open-ended math questions that are valid and reliable, so that they are used to measure students' creative skills in problem solving. Based on the results of the field test (20% of students are very creative, 30% creative, 10% quite creative, 5% not creative, and 5% very not creative), this proves that the instrument developed is able to differentiate the level of student ability. This study concludes that the development of math questions with an open-ended approach is feasible to be applied to measure creative thinking skills in solving math problems related to the two-dimensional plane geometry topic.      Keywords: creative skills, feasibility of mathematical problems, open-ended approach, two-dimensional plane geometry topic.

Abstract

Sentiment analysis is a study that analyzes a person's emotions about a problem. The military barracks program proposed by the Governor of West Java has drawn pros and cons from the community, especially in application X. Some people consider this program to be the right solution to discipline and shape the character of students, others think that the program can take away children's freedom and rights and does not guarantee any change in character after the students leave the military barracks. Therefore, a sentiment analysis was conducted with the aim of understanding public sentiment and comparing the accuracy of the SVM and Naïve Bayes in predicting public sentiment towards the military barracks program. The method in this study begins with data crawling, data selection, labeling, data preprocessing (data cleaning, normalization, case folding, stopword removal, tokenizing, stem), TF-IDF, Word Cloud, classification with Naïve Bayes and SVM, ending with a Confusion Matrix. In contrast to SVM, which revealed that 1429 tweets had positive sentiment and 447 had negative sentiment, Naïve Bayes results indicated that 1309 tweets had positive sentiment and 567 had negative sentiment. The accuracy value of the Naïve Bayes was 91.24%, the precision was 99.73%, and the recall was 82.94%. In contrast, the SVM achieved 92.16%, the precision was 97.86%, and the recall was 86.40%. Based on these findings, it can be said that the SVM  is more accurate than Naïve Bayes and that the public generally has a favorable opinion of the military barracks program.

Abstract

The dynamics of development and integration of information technology in education require the application of innovative learning strategies, methods and models, one of which is the Project-Based Learning (PjBL) model. This model is effective in developing students' 21st century skills such as critical thinking, creativity, and collaboration. However, the facts in the field show that most teachers in SMK Malang Regency do not understand the concept or implementation of PjBL. This study aims to improve teachers' understanding and skills in implementing PjBL through training designed based on the ADDIE model, namely: (1) training needs analysis, (2) design, (3) development, (4) implementation, and (5) evaluation. This training was attended by 14 SMK teachers in Malang Regency with teaching backgrounds in Animation, Visual Communication Design, Network Computer Engineering, and Broadcasting subjects with blended training methods (face-to-face and online) on 22 May 2024, 24 May 2024, 30 May 2024, and 6 June 2024. The evaluation results showed significant improvement in teachers' understanding and skills in designing PjBL-based learning tools, with a final average score of 87.8. The training made a positive contribution in supporting teachers to adapt and develop project-based learning in vocational schools, in line with the demands of international education quality standards implemented at SMKN 1 Singosari Malang. The output of this activity produced training materials in the form of powerpoint, video documentation and online mass media publications.
