Abstract

Education plays an important role in forming a generation that is competitive and superior amidst the complexity of the era of globalization. Ki Hajar Dewantara, who came from a noble lineage from the Yogyakarta Palace, devoted himself to education with full commitment. His philosophical doctrine of National Education reflects his belief that education functions as a pathway that guides individuals towards optimal well-being and happiness in society. According to Dewantara, education functions as a compass for the development of each student, not only depending on the will or authority of the teacher. Currently, the government is formulating a new educational paradigm that features flexibility for educators to adapt classroom teaching, using the Teaching at the Appropriate Level (TaRL) methodology. The correspondence between the characteristics of this new educational framework and Dewantara's educational principles fosters new optimism in the progress of Indonesian education. This study uses a literature review method to assess the resonance between the new educational paradigm and its practical implementation. The findings reveal a harmonious alignment between Ki Hajar Dewantara's philosophical teachings and the application of TaRL within the framework of modern education at the secondary school level. Therefore, integrating TaRL into the educational environment is a real step in realizing Dewantara's vision of building an inclusive and progressive educational landscape.

Abstract

This research is motivated by the need for teaching materials that are suitable for use in the 21st century, such as utilizing technology in using teaching materials for classroom learning. The use of teaching materials such as worksheets at SMP Muhammadiyah 9 Yogyakarta has implemented a scientific approach but has not been combined with the use of technology. The use of technology in learning is very diverse and can be realized in various supporting applications, one of which is flipbooks. Therefore, it is necessary to use scientific worksheets using the flipbook application. This research designs scientifically based flip worksheets for the subject Systems of Linear Equations in Two Variables that are valid and practical at SMP Muhammadiyah 9 Yogyakarta. Research and Development Methods using the ADDIE model will help achieve the objectives of this research accurately. With the support of instruments such as subject matter experts, media experts, and input from class VIII students, the development of flip worksheets produced very valid results in terms of content and media, with percentages of 94.23% and 90.00% respectively. Meanwhile, for the practical aspect, students gave a percentage of 72.60%, categorizing flip worksheets that were designed as practical.

Abstract

This research aims to determine the effectiveness of the differentiated learning approach to improve student literacy and numeracy. The type of research used was quasi-experimental, with research subjects consisting of 60 students in class XI Multimedia A and XI Multimedia B at Muhammadiyah 1 Sleman Vocational High School. Data was collected through tests, observations and interviews. Data analysis techniques include validity and reliability tests for instrument tests as well as normality tests, homogeneity tests, and t-tests to determine the effectiveness of differentiated approaches to increase student literacy and numeracy, as well as Gain tests to determine the type of improvement. The research results showed that the data was normally distributed and homogeneous, so it was continued with the t-test. The t-test results are 0,000 < 0,05, meaning that the differentiated learning approach is effective in increasing student literacy and numeracy with an increase in the Gain test of 0.72 in the high category

Abstract

This study aims to identify problems in the field by describing the challenges faced by teachers in implementing the Teaching at the Right Level (TaRL) approach to mathematics learning in class X-A. This study uses a qualitative descriptive method. The data analyzed includes primary and secondary data collected through interviews, observations, and documentation. The data analysis process includes the stages of data reduction, data presentation, and drawing conclusions, while the validity of the data is tested using triangulation techniques. The results of the study revealed a number of challenges in implementing the TaRL approach, namely: (1) lack of teacher understanding of the TaRL concept and techniques, (2) a heterogeneous classroom environment with 30 students, (3) limited time, costs, and monitoring of learning implementation, (4) minimal resources such as learning devices, and (5) limited training and socialization related to learning planning and evaluation with the TaRL approach. To overcome these challenges, schools or principals need to provide support in the form of training on the TaRL learning approach for teachers, as well as provide adequate facilities, learning resources, and budget allocations that support the implementation of learning.

Abstract

Poetry writing competency in the Merdeka Curriculum is crucial in Indonesian language learning, but many students struggle to express creative ideas due to a lack of innovative teaching strategies. The acrostic technique, chosen for its clear structure and ability to stimulate imagination through keywords, was employed to address this challenge. This study analyzes the effectiveness of the acrostic technique in improving poetry writing skills among class VIII students at State Junior High School 3 Banguntapan. A quasi-experimental method with a Control Group Pre-test and Post-test Design was used, with two classes: the experimental class (40 students) using the acrostic technique and the control class (40 students) using conventional methods. Data were collected through tests and interviews. The findings reveal that the acrostic technique significantly improved students' writing skills compared to conventional methods, with a significance value of 0.000. This study contributes to the development of innovative teaching methods that enhance students' writing abilities in language and literature education.

Abstract

This study aims to describe the implementation of economics learning at SMA Muhammadiyah Mlati and its impact on shaping students’ frugal behavior. The research employed a qualitative approach and was conducted August 2025, involving the principal, vice principal for curriculum affairs, economics teacher, and tenth-grade students as subjects. Primary data were obtained through observation, interviews, and documentation, while secondary data were derived from supporting documents and photographs. Data analysis followed the Miles and Huberman model, which includes the stages of data collection, reduction, presentation, and conclusion drawing. The findings reveal that economics learning was designed contextually by linking theory to real-life practices and employing interactive and motivational methods to address time constraints and student boredom. The impact of this learning process is evident in the improvement of students’ understanding of economic concepts and their application in daily life, such as saving, budgeting, and avoiding consumptive behavior. Therefore, economics learning at SMA Muhammadiyah Mlati not only enhances academic competence but also fosters Islamic character values of frugality, discipline, and responsibility.
