Abstract

This study was conducted based on the researcher's observation of class V of SD Negeri 122354 Pematangsiantar that teachers still use conventional learning models so that students are less involved in the learning process. This causes the learning process to be less than optimal and student learning outcomes do not meet the criteria for achieving learning objectives. From these problems, it is necessary to find a solution, including by implementing the Problem Based Learning learning model. This learning model can be applied to science subjects because it encourages students to work together and communicate with each other in completing their assignments. This learning model can improve the quality of science learning so that students are more active, creative, and learning is more meaningful so that learning outcomes increase. This study uses a quantitative method with a Pre-Experiment research type and a One Group Pretest-Posttest research design with a sample of 22 students. Based on the results of the hypothesis test with a significance level of 0.05 t count = 19.495 with a significant level (2-tailed) of 0.000 significant probability <0.05, t count> t table = 19.495> 1.717 then Ho is rejected and H1 is accepted. This explanation indicates that the Problem-Based Learning model has an influence on the science learning outcomes of fifth-grade students at the UPTD of SD Negeri 122354 Pematangsiantar.

Abstract

This study aims to develop a digital flipbook-based learning media on regional economic conditions and determine its feasibility for fifth-grade elementary students. The research was motivated by low student learning interest and the limited use of digital media in IPAS learning. This study employed a Research and Development (R&D) method using the ADDIE model, which includes analysis, design, development, implementation, and evaluation stages. The data were collected through expert validation questionnaires (material, language, and media experts) and responses from teachers and students, analyzed using a Likert scale. The results showed that the developed flipbook media was categorized as very feasible, with material expert validation at 93%, language expert at 91%, and media expert at approximately 93%. Teacher responses reached 92% and student responses 89%, both categorized as very feasible. Therefore, the digital flipbook learning media is suitable as an alternative learning tool in elementary schools.
