Abstract

This research aims to analyzed comparison the outcomes cognitif learning use Picture And Picture  learning model with Examples Non Examples learning model. This type of research is a quantitative research. The research design used was Quasi Experimental Design with design type The Matching Pretest-Posttest Comparison Group Design. The test is done twice before and after giving treatment (treatment) in the class. The subjeck in this study is divided into two groups: students of class IV A  in SDN 76 Kota Bengkulu as a experimental  group 1 and students of class IV B at SDN 76 Kota Bengkulu as experimental group 2. The research instrument used is a learning result test with multiple choice questions given through pretest before the learning takes place and posttest after the learning takes place. Data of this research are analyzed by using descriptive analysis and inferential analysis that is t-test (independent sample t-test). Data of research result which is processed by using t test obtained t hitung equal to 2,34 and ttabel value equal to 1,667. Systematically seen thitung 2,34 > ttabel 1.667 at 5% significant level, This shows that there are differences in learning outcomes between students taught by using pictures and pictures learning model with examples non examples learning model. then the average of the result study of Picture and Picture learning model was (68,22) and Example Non Example was (58,03).The concluded that the Picture and Picture learning model more effective to highest students result study.

Abstract

This systematic literature review examines the effectiveness of Problem-Based Learning (PBL) e-modules in developing students' 21st-century skills by synthesizing ten Scopus-indexed empirical studies published between 2015 and 2025. Motivated by the growing demand for student-centered and technology-integrated learning, this review aims to consolidate evidence on how PBL-oriented digital modules support key competencies. Following the PRISMA guidelines, the study employed a transparent selection process and combined thematic synthesis with bibliometric analysis (VOSviewer) to identify research trends, dominant themes, and learning outcomes. The findings indicate that PBL e-modules consistently enhance critical thinking, collaboration, communication, and creativity, with the strongest effects reported in critical thinking and collaborative performance. Student motivation and autonomy emerged as important mediating factors, while variations in instructional design and digital platform quality influenced effectiveness across contexts. These results imply that well-structured PBL design and purposeful digital integration are critical for maximizing the impact of e-modules on 21st-century skills, while also highlighting methodological gaps for future research.
