Abstract

This study aims to determine the effect of the Problem Based Learning (PBL) model assisted by number card media on the mathematics learning outcomes of second-grade students at SDN Semeru 1 Kota Bogor in the topic of place value. The research problem is based on the low understanding of place value concepts and the dominance of conventional teaching methods in the classroom. This study employed a quantitative approach using a quasi-experimental method with a One Group Pretest-Posttest design. The research subjects consisted of 25 students. The instruments used were pretest and posttest questions that had been validated by experts. The results showed an increase in the average score from 45.23 to 75.18 with a gain score of 64.89%, which is categorized as high. The t-test showed a t-value of 12.456 with a p-value of 0.000 (< 0.05), indicating a significant difference between the pretest and posttest results. The use of concrete media in the form of number cards effectively helped students understand abstract mathematical concepts, while the PBL model was able to increase active student engagement in the learning process. The findings conclude that the combination of PBL and number card media can significantly improve mathematics learning outcomes while providing a meaningful and contextual learning experience. Therefore, active, innovative, and contextual learning approaches are recommended to be implemented in primary school mathematics learning.

Abstract

This study aims to analyze the influence of transformational leadership on innovative work behavior through its three dimensions idea generation, idea promotion, and idea realization with job satisfaction acting as a mediating variable in the context of public healthcare organizations. A quantitative explanatory approach with a cross-sectional survey design was employed. Data were collected from 152 civil servants working at a regional public hospital in Indonesia using a structured questionnaire and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS. The results reveal that transformational leadership has a positive and significant effect on idea generation, idea promotion, idea realization, and job satisfaction. Job satisfaction also shows a positive and significant influence on idea generation and idea promotion but does not significantly affect idea realization. Furthermore, mediation analysis indicates that job satisfaction partially mediates the relationship between transformational leadership and both idea generation and idea promotion, while no mediating effect is found for idea realization. These findings imply that transformational leadership and employees’ positive work attitudes play an important role in encouraging innovation in public healthcare organizations, particularly in the early stages of innovation processes, highlighting the need for leaders to foster supportive work environments that enhance employee satisfaction and innovative engagement.
