Digital literacy is a crucial competency for teachers. Accelerating digital literacy for elementary school teachers is not only about mastering digital tools and applications, but also about changing mindsets and approaches to teaching. There are three impacts for teachers and students if teachers are unable to master digital competencies: 1) teachers are less able to keep up with the latest technological developments; 2) teachers are unable to filter and process the latest information, resulting in a tendency towards misinformation; 3) students are less able to absorb the latest information and thus misuse the wrong sources of information. Given these impacts, training and mentoring are needed for elementary school teachers in Songgom District to acquire the right digital skills so that elementary school teachers can maximize their potential. Elementary school teachers in Brebes Regency still do not have good digital competencies. If left unchecked, more and more teachers will lack digital competency. This can lead to a lack of technology-related information that students can use to support their learning. Furthermore, inadequate technology skills can hinder differentiated learning within the independent curriculum. The Community Service Program, initiated by professors and lecturers with expertise in digital literacy and language, is highly relevant to the needs of teachers in Brebes Regency. Elementary school teachers are developing digital competencies by implementing interactive quiz-based learning and Canva-based learning media. These competencies can be applied by teachers in the classroom. Students are expected to absorb the material more meaningfully. Learning through the application of digital literacy by teachers will increase student interest and engagement in learning the material.

The Community Service Program (KKN) is the answer for students to face these challenges. Elementary school students' awareness of saving is still relatively low. Many students prefer to spend their pocket money on momentary desires rather than saving it. This condition indicates that financial literacy in children is still limited. The main objective of this socialization activity is carried out with an approach that is appropriate to the age of elementary school children, for example, such as games, simulations, or simple counseling. By using such methods, students not only understand the concept of saving, but also have a desire to do it. In addition, this socialization activity instills an attitude of independence and discipline. The socialization program was held as an effort to provide insight and instill awareness to students of Elementary School 014662, Gunung Melayu Plantation Village, Rahuning District, Asahan Regency, and was attended by students in grades 4, 5, and 6 regarding the benefits of saving. To facilitate student understanding, the team demonstrated the practice of saving by using piggy banks and money as concrete examples. After students received material on the importance of saving, the activity continued with a quiz session to increase enthusiasm and test their understanding of the newly presented material. The socialization of the love of saving program, carried out through the Community Service Program (KKN), has proven to be effective in fostering understanding and awareness among elementary school students about the importance of saving from an early age.

Education is a crucial foundation for shaping a generation with strong character, faith, intelligence, and responsibility as mandated by Law Number 20 of 2003. In the 21st century, one of the most essential competencies to be developed is critical thinking, which can be effectively nurtured through Project Based Learning (PjBL). This approach actively engages students in planning, inquiry, problem-solving, and reflection within project-based tasks, making learning more meaningful. This study examines the effect of PjBL on the critical thinking skills of fifth-grade students in Natural and Social Sciences (IPAS) at SD Islam Istiqomah, Ungaran Barat, Semarang Regency. Employing a quantitative method with a quasi-experimental Nonequivalent Control Group Design, the study involved 76 students divided into experimental and control groups. Data were collected using a validated and reliable essay test on critical thinking skills. Results showed that the experimental group achieved a higher mean posttest score (84.16) than the control group (74.74). The point-biserial correlation was rpb = 0.676, and the t-test result (tcount 7.891 > ttable 1.993, p < 0.05) confirmed a significant difference. These findings demonstrate that PjBL substantially improves students’ critical thinking and emphasize its continued implementation to foster contextual and meaningful IPAS learning.

This research is motivated by the low cognitive abilities of students in science learning in elementary schools, which is largely caused by conventional teaching methods that do not actively involve students. To overcome this problem, the Team Assisted Individually (TAI) learning model is used, which combines a cooperative approach and individual learning to improve the understanding of science concepts more effectively. The purpose of this study is to determine the effect of the TAI model on the cognitive abilities of fifth-grade students of SD Islam Baitul Salam Ciledug on natural phenomena material. This study uses a quantitative approach with a quasi-experimental design and a pretest-posttest control group design technique. The sample consists of two classes, namely the experimental class that uses the TAI model and the control class that uses conventional learning methods. The results of the study show that there is a significant increase in the cognitive learning outcomes of students who participate in learning with the TAI model compared to the conventional method. Therefore, this study is expected to provide an alternative effective learning model for teachers, as well as improve the quality of the process and student learning outcomes, especially in science learning.
