Low science learning outcomes at the junior high school level are a major problem caused by the dominance of conventional, teacher-centered teaching methods. The purpose of this study is to examine various innovative learning strategies, how effective they are, and their impact on student learning outcomes. The literature review method was used to review national and international articles published between 2020 and 2025 that discuss the application of innovation-based learning strategies in science. The strategy patterns, implementation effectiveness, and their impact on student learning outcomes were analysed using content analysis techniques. The research findings indicate that strategies such as problem-based learning (PBL), project-based learning (PjBL), discovery learning, environmental-based learning, and cooperative learning using the Think-Pair-Share (TPS) method are effective in increasing students' motivation and activity, as well as their learning outcomes in the cognitive, affective, and psychomotor domains. Generally speaking, the strategies are all student-centered. This is demonstrated by the constructivist approach, which emphasises contextual and collaborative learning. The results of this study indicate that implementing a creative learning approach can be an effective way to improve the quality of science learning and student learning outcomes in junior high school.

The main problem faced by MA Al Ulya Al Mubarok is the low level of financial literacy and the lack of understanding of the importance of early investment. Most students still perceive saving as the only form of financial management without recognizing the potential for asset growth through safe and well-planned investments. The absence of practical education on personal financial management and limited access to learning resources about investment are the main barriers to developing intelligent and future-oriented financial behavior. As a solution, this community service program is designed to improve financial literacy and foster investment intention among students. The program will be implemented through several stages of activities, including: needs and baseline analysis of students, development of a contextual-based financial literacy module, interactive socialization and training on the basic concepts of saving, personal financial management, and introduction to investment. The expected outcomes of this program include: an increase in students’ financial literacy level by at least 30% based on pre-test and post-test results, the initiation of a student investment awareness community, and the creation of a financial literacy learning module that can be used sustainably by the school. This community service program is expected to serve as a model for financial literacy development in secondary education institutions while supporting national efforts to build a financially literate, independent, and future-oriented young generation.

The era of globalization is an era of quality competition, where only thosebwith high competence will be able to compete in the free market. Therefore, developing high-quality human resources is something that cannot be compromised. Education that supports development in this era is education that can foster students’ potential’ enabling them toface and overcome life’s challenges. Thus, in the learning process, teachers should not only serve as models or sources of knowledge but also act as learning managers. As learning managers, teachers play an important role in creating a learning environment that allows students to learn confortably and effectively. Based on observations at SMA Negeri 2 Taniwel, it was found that students in class X-2 have low learning outcomes in sociology. The writer’s observation in class indicated that sociology learning was dominated by lecture methods, resulting in students being less active during the learning process. According to research conducted by Al Muchtar (1991), learning in social studies education does not sufficiently simulate students to be actively involved in the learning process. Furthermore, the teaching and learning process of social studies carried out bye teachers has not been able to faster a learning culture among students, wich in turn significantly affects their learning achievement and outcomes. To support active learning strategies, teachers can apply various relevant learning models. Therefore, the learning process will become more varied, innovative, and constructive, creating interaction between teachers and students, among students themselves, and between students and other learning resources.

Intellektika : Jurnal Ilmiah Mahasiswa 2025 STIKes Ibnu Sina Ajibarang

This study explores the alignment between science learning practices and children’s cognitive development stages based on Jean Piaget’s theory. Ten academic publications were systematically reviewed to examine how Piaget’s framework can be applied in science education. The findings highlight that integrating cognitive development theory is highly relevant for improving the quality of teaching and learning in schools. At the concrete operational stage (approximately 7–11 years), children learn best through direct experiences, manipulation of real objects, contextual media, and experiments that connect concepts with daily life. These methods help foster curiosity and reinforce conceptual understanding. As learners progress to the formal operational stage (around 11 years and above), they begin to think abstractly, reason logically, and analyze critically. At this level, student-centered approaches, inquiry-based methods, and constructivist learning become more effective in enhancing problem-solving, creativity, and higher-order thinking skills. The review also indicates that adapting instruction to developmental stages supports more meaningful and sustainable learning outcomes. In the Indonesian educational context, this approach can address challenges such as limited classroom facilities, diverse student learning styles, and a curriculum that is often overloaded. By applying Piaget’s insights, teachers can design learning strategies that bridge abstract concepts with concrete understanding, thus increasing student motivation and engagement. In conclusion, aligning science education with Piaget’s cognitive stages is an effective way to improve student performance and ensure long-term academic growth. The study provides valuable input for teachers, researchers, and policymakers in developing innovative, student-centered science and mathematics education.
