Teaching plane geometry often faces challenges due to the abstract nature of geometric concepts, which are often detached from students’ real-life contexts. This study is a development research (Research and Development) using a modified 4D model reduced to 3D (Define, Design, Develop) aimed at producing and testing the validity of a Student Worksheet based on ethnomathematics with Batik Sekundang motifs on plane geometry material oriented toward Contextual Teaching and Learning (CTL). Validation was conducted by two mathematics education experts who assessed the feasibility of content/material, media, and language/readability using a Likert scale instrument. The data were analyzed quantitatively in a descriptive manner using percentage formulas to determine the level of validity. The results showed that the student worksheet obtained a validity percentage of 87.50% in content feasibility (very valid), 80.76% in media (valid), and 87.50% in language (very valid), with an overall average of 85.25%, which falls into the very valid category. Based on these results, the ethnomathematics-based student worksheet with Batik Sekundang motifs is declared suitable to be used as a supporting teaching material for contextual and meaningful plane geometry learning for students in South Bengkulu.

This study discusses the development of thematic teaching materials in elementary schools to improve the quality of learning in accordance with the 2013 Curriculum. The research method used is research and development with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The results show that the thematic teaching materials developed with approaches such as Project Based Learning (PjBL), Problem Based Learning (PBL), and Contextual Teaching and Learning (CTL) can enhance students' critical thinking, creativity, and social responsibility skills. The integration of local wisdom values as well as the use of digital and contextual teaching materials make learning more engaging, interactive, and meaningful. The thematic teaching materials based on these innovative learning models can help students develop 21st-century skills. Thus, the development of thematic teaching materials based on innovative models is an effective strategy for creating quality learning in elementary schools that is relevant to curriculum demands and the needs of today's learners. The use of technology and contextual approaches enriches students' learning experiences, making them more relevant and beneficial in daily life.

This study looks at how the Contextual Teaching and Learning (CTL) model is used in Christian Religious Education (CRE) and checks how it helps students develop their critical thinking abilities. In today’s education system, students are not just expected to remember Bible stories, but also to understand what they mean, think about the moral lessons, and use Christian values wisely in their everyday lives. However, past observations show that CRE classes often use a lot of lectures and memorization, which doesn’t give students much chance to think deeply or link what they learn to real-life situations. The CTL model provides a better way for learning by using seven key parts: constructivism, inquiry, questioning, learning community, modeling, reflection, and real-world assessmen. A descriptive qualitative design was employed involving CRE teachers and students selected purposively from classes that have integrated CTL in online and face-to-face settings. Data were collected through classroom observations, semi-structured interviews, and instructional documents. The analysis followed Miles and Huberman’s stages of data reduction, display, and conclusion drawing, supported by triangulation to strengthen credibility. The findings reveal that CTL enhances student engagement, promotes higher-order reasoning, and supports the internalization of Christian values in real-life contexts. Supporting factors include a positive school climate, parental involvement, and teacher readiness, whereas obstacles emerge from limited facilities, large class sizes, and insufficient teacher understanding of CTL. The study underscores the need for context-based and character-oriented instructional designs in CRE.

This study examines the role of the contextual teaching and learning (CTL) model in supporting teachers to create active and meaningful learning experiences. The research highlights the importance of linking instructional content with students’ real-life contexts to strengthen conceptual understanding and improve problem-solving abilities. Through descriptive analysis, this paper outlines the main components of CTL, including constructivism, inquiry, questioning, learning communities, modeling, reflection, and authentic assessment. The findings show that the CTL model enables students to construct knowledge independently, apply concepts to practical situations, and develop critical thinking skills. Furthermore, this study describes challenges faced by teachers across educational levels—such as limited time, students’ low independence, and variations in academic abilities—and proposes practical solutions to address them. The implications of this study emphasize the need for teachers to design engaging learning activities, build supportive classroom environments, and integrate authentic assessment to measure students’ holistic progress. Overall, CTL serves as an effective model for enhancing learning relevance, increasing student participation, and preparing learners to face real-world challenges.

This qualitative case study examines how the Communicative Language Teaching (CLT) approach can be adapted to general English classes in a higher education institution in Timor-Leste to answer the long-standing question of how students can acquire speaking proficiency in a multilingual learning environment. The paper brings into focus the incorporation of CLT into classroom activities with special emphasis on the application of role play, pair work, seminars, simulations, and task-based learning as means of promoting interactive and communicative competence. A descriptive qualitative case study design was used to develop in-depth knowledge of contextual teaching and learning experiences, the perspectives of the participants, and naturally occurring practices in the institutional setting. Semi-structured interviews, classroom observations, and document analysis were the data-gathering methods. Purposive sampling was used to select the two lecturers and seven students directly involved in teaching general English. Thematic analysis was used to analyse the data, which made it possible to identify repeated themes and patterns that revealed both opportunities and difficulties in implementing CLT in context. The results of the study indicate that, despite the adaptation of the CTL approach in teaching practices, its implementation is often sporadic due to concerns about English proficiency, teacher training, and flexibility in using local and official languages during instruction. The research demonstrates the necessity of adapting CLT methods to the local education environment and arranging long-term professional development for lecturers. This study helps us understand how context-sensitive CLT approaches can lead to improved results in teaching and learning English in Timor-Leste. The interactive approach and the systematic teacher model could significantly improve students' communicative competence.

Numeracy is an important skill that elementary school students must have, but in reality it is still relatively low because learning tends to be conventional and less contextual. Numeracy does not only include the ability to count, but also the ability to understand, use, and interpret numbers and data in various daily life contexts. One of the causes of low student numeracy is a learning approach that is less interesting and not related to real situations. This study aims to test the effectiveness of the contextual learning model (Contextual Teaching and Learning/CTL) in improving students' mathematical numeracy skills. The research design used was a one-group pretest-posttest experiment with 23 fifth-grade students of SDN 002 Teluk Bintan as subjects. The instrument in the form of a numeracy test was given before and after the implementation of CTL, then the data were analyzed using prerequisite tests (normality and homogeneity) followed by a paired sample t-test. The results showed a significant increase in students' numeracy skills. The average pretest score of 24.78 increased to 73.91 in the posttest with a significance value of 0.000 <0.05. This increase proves that CTL is effective in helping students master numeracy through a learning process that links mathematical concepts with real experiences. Thus, the contextual learning model can be an alternative learning strategy that is relevant for increasing elementary school students' numeracy, while emphasizing the importance of implementing a more applicable approach in mathematics learning.

This study aims to determine the effect of the Contextual Teaching and Learning (CTL) learning model on students' ability to review fictional works in class VIII of SMP Negeri 1 Gunungsitoli. This study uses a quantitative approach with a quasi-experimental method, with a non-equivalent control group design. The population in this study were all students of class VIII of SMP Negeri 1 Gunungsitoli, while the research sample consisted of two classes, namely class VIII-C as the experimental class and class VIII-F as the control class, each totaling 31 students. The research instrument used was a pretest and post-test in the form of essays. The results of the validity test showed that all test items were valid with a calculated r value > r table (example: question number 3 r count = 0.905 > r table = 0.367). The reliability test showed a value of α = 0.78 which means the instrument is reliable. The difficulty level ranged from 69.60% to 77.33% (moderate to easy category), and the discriminating power ranged from 0.20–0.32 (sufficient to moderate category). The average pretest score for the experimental class was 63.58, and the posttest score increased to 80.61. Meanwhile, in the control class, the average pretest score was 62.38, and the posttest score increased to 71.35. Based on the results of the independent t-test, t = 3.82 and t = 2.00 were obtained at a significance level of 5%. 

This study aims to improve students' motivation and learning outcomes through the application of the Contextual Teaching and Learning (CTL) approach to fourth-grade students of SD 1 Pecangaan. The background of this study is the low motivation and learning outcomes of students in the conventional learning process that does not relate the material to students' real lives. The research method used is the Classroom Action Research (CAR) model of Kemmis and McTaggart which is carried out in two cycles. The instruments used include observation, learning motivation questionnaires, and learning outcome tests (pretest and posttest). The results of the study showed a significant increase in student motivation and learning outcomes after the application of the CTL approach. Students' learning motivation scores increased from the sufficient category (average 62) to high (average 83). Student learning outcomes also increased from an average pretest score of 63 to an average posttest score of 82, with the percentage of learning completion increasing from 35% to 87%. The CTL approach has proven effective because it is able to create active, meaningful, and relevant learning with students' real experiences. Thus, the application of CTL can be used as a strategic solution in improving the quality of learning in elementary schools. Teachers are expected to be able to implement this approach creatively and sustainably so that learning becomes more contextual and enjoyable for students.

This research was motivated by initial observations at Ziyadatul Iman Elementary School, which showed that the school used Student Worksheets (LKS) without textbooks, and there was a need for relevant and engaging teaching materials. This study aimed to develop Student Worksheets (LKPD) based on Contextual Teaching and Learning (CTL) at Ziyadatul Iman Elementary School. The development model used was the ADDIE model, with the trial subjects being grade IVB students at Ziyadatul Iman Elementary School.. The validation results showed that the LKPD was very valid by linguists (95%), valid by material experts (80%), and media experts (80%). The responses of teachers (96%) and students (94% of small groups, 92.6% of large groups) were also very good. In conclusion, this LKPD is suitable for use to improve student understanding and learning outcomes.

This study aims to examine teachers' strategies in improving students' understanding of effective sentence concepts through the implementation of the Contextual Teaching and Learning (CTL) model in elementary schools. The issues addressed in this research include how teachers design and implement context-based learning strategies, the challenges encountered during implementation, and the impact on students’ understanding of effective sentence structures. This research employs a literature review method by analyzing various journals, scholarly articles, and relevant documents. The findings indicate that teaching strategies that connect instructional materials with students’ real-life contexts—through CTL components such as constructivism, inquiry, questioning, learning community, modeling, reflection, and authentic assessment—are proven to significantly enhance students’ understanding of effective sentences. Furthermore, the implementation of interactive and meaningful strategies also increases student participation and fosters positive attitudes toward learning the Indonesian language. However, the application of CTL faces several challenges, including limited instructional time, teacher readiness, and diverse student abilities. Therefore, support from the school and professional development for teachers is essential to ensure that CTL-based teaching strategies can be implemented optimally and sustainably.

This research is a quantitative research using quasi-experimental design. Before receiving treatment, the experimental group and the control group were given a pre-test to evaluate students' science literacy. The location of the research was carried out on Jalan Lintas Riau, class IV SDN 0401, Pasar Ujung Batu Village, Sosa District, Padang Lawas Regency, North Sumatra Province. The research time was carried out in the odd semester in July-October 2024/2025. The sample of this study used 25 students, namely the experimental and control classes. The data collection technique for this study used tests and interviews. Based on the results of the study, the increase in students' science literacy skills was also strengthened by empirical findings in this study, where the average post-test score in the experimental class reached 80.16, much higher than the control class which only reached 73.20. In addition, the results of the t-test showed a very small significance value (p = 0.000056), indicating that the difference in learning outcomes between the two classes was not a coincidence, but a real result of the application of the CTL model. The fact that the experimental class showed lower variance in the posttest also indicates that the CTL model is able to balance achievement between students and reduce academic gaps.

The purpose of this research is to examine how the CTL Learning Model affects third graders' conceptual understanding at MI Al-Munawwarah in Jambi City.  The research goals informed the selection of class 3.2, which yielded a research sample of 30 kids, for this third grade study that employed a sampling approach known as purposive sampling.  A one-group pretest and posttest design was used in this investigation.  In this work, we employed a test-and-observation design to gather data; we administered the test before (pretest) and after (posttest) learning using the CTL model.  To determine the impact, a t-test is used in a hypothesis test.  The significance value of 0.000 <0.05, obtained from the SPSS 26 statistical calculation using the paired sample t-test, indicates that the calculated statistics (output t number) <table statistics (t table) concluded that H0 was rejected and ha was accepted. Consequently, the CTL learning model influenced the comprehension of the concept of learning outcomes among class III students at MI Al-Munawwarah, Jambi City.  

This study focuses on the effect of applying the Contextual Teaching and Learning (CTL) model in the topic of reaction rate on the ability to think critically and the formation of character values of students in geographically remote areas (remote areas). This approach is designed to strengthen learners' understanding of scientific concepts in a relevant and contextual manner, by connecting them to the dynamics of real life - both in the personal, social and cultural domains. Thus, learners have the opportunity to build conceptual insights and adaptive skills independently. In addition, this real situation-based method contributes to fostering character values such as responsibility, discipline, innovation, curiosity, as well as social interaction skills and effective communication during the learning process. The literature review was conducted by collecting scientific publications released between 2018 and 2025. The findings of this review confirmed that the CTL approach has a real positive impact in honing critical thinking skills and fostering learners' character that supports their academic achievement. Therefore, it can be concluded that CTL is an efficient and relevant pedagogical method to be applied in teaching high school chemistry.
