This study aimed to develop and evaluate Augmented Reality (AR)-based learning media to enhance students’ cognitive abilities at State Vocational High School (SMK Negeri) 2 Pati, particularly in the subject of Computer Networking and the Internet. The research was motivated by low student achievement in meeting the Minimum Mastery Criteria (KKTP), which was primarily attributed to the continued reliance on traditional teaching methods and low student motivation. A research and development (R&D) approach was employed using the ADDIE model. The resulting AR media is an Android application that integrates text, audio, images, animations, interactive 3D objects, and simulations, and is in accordance with the Merdeka Curriculum. Expert evaluations showed a very high level of feasibility, with ratings of 94% from a subject matter expert and 91% from a media expert. These results were further supported by Aiken’s V index, which indicated very high validity for the material (0.921) and high validity for the media (0.881). A practicality test was conducted, revealing a high level of effectiveness, with a 94% approval rating from both teachers and students. Moreover, a pretest–posttest control group design demonstrated significant progress in learning outcomes. The experimental group achieved an average post-test score of 83.75, significantly higher than the control group’s 73.60. Based on the N-Gain test, the experimental group achieved an average gain of 65.52% (moderately effective), whereas the control group achieved only 38.75% (ineffective). This study contributes to the theories of learning transfer, connectivism, and heutagogy, and offers practical implications for vocational education in adopting innovative technologies.

In conclusion, the e-module effectively enhanced student comprehension of the starter system. Students expressed a preference for digital learning media due to its flexibility in being accessed anytime and anywhere, both online and offline.

The teaching of Pancasila and Civic Education (PPKn) in Vocational High Schools (SMK) still faces challenges in delivering material that is engaging and easy to understand. The abstract nature of Pancasila values often makes them difficult to grasp without supportive media. The lack of interactive and digital-based learning media becomes a barrier to meaningful learning. Therefore, this study aims to develop Canva-based interactive learning media within a Project-Based Learning (PjBL) model to improve students’ cognitive abilities in PPKn subjects at SMK.
This research is a type of Research and Development (R&D) using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The developed product is a digital interactive media using Canva, presenting Pancasila content visually, communicatively, and contextually. Validation was conducted by two media experts and three content experts. Practicality was tested through questionnaires to teachers, while effectiveness was evaluated using pretests and posttests in experimental and control classes. The implementation was carried out using a project-based learning approach.
The results show that: (1) the media visualizes Pancasila values effectively and attractively; (2) expert validation confirms its feasibility with media expert CVI at 0.88 (PoA 88%) and content expert CVI at 0.91 (PoA 91%); (3) practicality is in the “very practical” category (average score 93.3%); and (4) effectiveness testing indicates a significant difference (t = 4.727; sig. = 0.000) and higher N-Gain in the experimental class. Therefore, Canva-based interactive media is feasible, practical, and effective for project-based PPKn learning in SMK.
