The purpose of this study is to improve the understanding of fifth-grade students on the material on the human digestive system by using the Project-Based Learning (PjBL) learning model. The method used in this study is classroom action research consisting of 2 cycles with four stages, namely planning, action, observation and reflection. The data analysis techniques used in this study are participatory observation techniques, data utilization techniques and document data analysis. The subjects of the study were 15 fifth-grade students. The results of the study showed that students' understanding increased after the PjBL model was applied, as evidenced by the percentage of students' average scores in the pre-cycle not reaching the criteria for achieving learning objectives; then in cycle I, the score increased by 13% and in cycle II it increased by 20%. This research is expected to contribute to educational institutions to provide information in improving the quality of education.</p> Fiskawati Derate Asprila Singgih Subiyantoro Copyright (c) 2025 Fiskawati Derate Asprila, Singgih Subiyantoro https://creativecommons.org/licenses/by-sa/4.0 2024-12-31 2024-12-31 2 2 40 48 10.32585/cognitive.v2i2.36 The Use of Quizizz Media to Increase Students' Interest in Learning Science at Primary Schools http://ojs.edutechpublishing.com/index.php/cognitive/article/view/38 <p>Learning media must be used to improve the quality of learning in the digital era. Learning media can inspire and motivate students to learn which will later increase students' interest in learning. This research aims to increase the learning interest of class IV students using learning media in the form of Quizizz. This type of research is Classroom Action Research, with the research subjects being class IV students, totaling 15 children, 6 girls, and 9 boys. Using instruments in the form of observation data, evaluation tests, and interviews. The Classroom Action Research design was carried out in 2 cycles with each cycle going through the stages: (1) Planning, (2) Implementation of Action, (3) Observation, and (4) Reflection. The results of this research show that the learning interest in fifth-grade increases by using Quizizz media. Based on the results in cycle I, without using the Quizizz application, the % of student's interest in learning was 59.64%, classified as in the medium category. Meanwhile, in cycle II, with the implementation of the Quizizz application, the percentage of interest in learning increased to 74.29%, entering the high category. This increase proves that the use of Quizizz interactive learning media is effective in increasing students' interest in learning. Therefore, implementing Quizizz in the learning process is an effective strategy for teachers to increase students' interest in learning in fifth-grade.</p> Sofa Binti Masruroh Edi Handoko Singgih Subiyantoro Copyright (c) 2025 Sofa Binti Masruroh Edi Handoko, Singgih Subiyantoro https://creativecommons.org/licenses/by-sa/4.0 2024-12-31 2024-12-31 2 2 49 58 10.32585/cognitive.v2i2.38 The Role of Counselors in Handling Traumatic Victims of Sexual Violence http://ojs.edutechpublishing.com/index.php/cognitive/article/view/42 <p>Sexual violence is a case of violence that still occurs in Indonesia, even Sukoharjo Regency.
