Abstract

The low achievement of Indonesian students in the Programme for International Student Assessment (PISA) highlights the need for innovative learning models that not only emphasize cognitive aspects but also foster students’ character development. This study aims to develop a Problem Based Learning (PBL) model integrated with Higher Order Thinking Skills (HOTS) and character education to improve the literacy skills of elementary school students. The research employed a Research and Development (R&D) approach using the ADDIE development model, which consists of analysis, design, development, implementation, and evaluation stages. The study involved 28 fourth-grade students. The research instruments included validation sheets, observation sheets, student and teacher response questionnaires, and literacy tests covering reading, numeracy, science, and digital literacy. The results indicate that the learning model was considered highly valid with an average validation score of 88.5%. The implementation of the PBL-HOTS-Character model significantly improved students’ literacy skills with an average score of 87.5, consisting of reading literacy (88), numeracy (85), science literacy (87), and digital literacy (90). Students’ character education also improved with an average score of 73.4. The two-way ANOVA analysis revealed that the learning model, character education, and their interaction had a significant effect on students’ literacy, with a determination coefficient of 66.1%. In conclusion, the PBL model integrated with HOTS and character education is effective in enhancing literacy skills while strengthening students’ character. This model is highly relevant to support the implementation of the Merdeka Curriculum and the realization of the Pancasila Student Profile.

Abstract

Mathematical representation ability is one of the fundamental skills needed by students to understand concepts and solve mathematical problems. However, the results of the study indicate that this ability is still low in most elementary school students. This study aims to develop a mathematics learning tool based on the Problem Solving approach and integrated with Ethnomathematics to improve students' mathematical representation ability. The study used the Research and Development (R&D) method with the Plomp development model consisting of three phases, namely initial research, development, and assessment. The research subjects were 30 students. The research instruments included validation sheets, teacher assessment sheets, student response sheets, implementation observation sheets, and mathematical representation ability tests (pre-test and post-test). The results showed that the developed learning tool met practical criteria with an average LKPD readability of 4.60 (very good category) and learning implementation of 94.5% (very good category), and was effective with an increase in the average pre-test score of 56.20 to a post-test of 83.87 and a gain score of 0.63 (medium-high category). Thus, there was a significant increase in the average post-test results of students' mathematical representation abilities, namely 83.87 through Problem Solving and Ethnomathematics-based learning devices.
