Abstract

The integration of Augmented Reality (AR) into technical and vocational education has gained considerable attention as a means of bridging the gap between abstract theoretical content and applied industrial competencies. However, empirical evidence regarding its effectiveness in mechanics of materials instruction, particularly within the context of manufacturing engineering training, remains limited. This study aimed to design, develop, and evaluate an AR-based instructional medium for tensile testing procedures, targeting competency development among engineering students. The development process followed the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) instructional design model, incorporating competency-based and mastery learning frameworks. A pre-experimental one-group pretest-posttest design was employed with 36 engineering students drawn from three higher education institutions in Indonesia. Media feasibility was assessed through expert validation, yielding scores of 79% for media quality and 91% for content accuracy, both indicating suitability for instructional use. Learning outcomes were measured using normalized gain (N-Gain) analysis, with results indicating a mean N-Gain score of 0.47, classified as moderate improvement according to Hake's (1998) criteria. These findings suggest that AR-based instructional media may serve as an effective tool for supporting technical training in mechanics of materials, particularly for facilitating three-dimensional visualization of complex physical phenomena such as tensile deformation and stress-strain behavior. Nevertheless, the moderate gain score indicates that further development, notably the incorporation of audio elements and higher-order synthesis tasks, may be required to fully support advanced competency levels. The study contributes empirical evidence to the growing body of literature on immersive technology integration in engineering education within Industry 4.0 contexts.

Abstract

In the digital era, mobile marketing has emerged as a critical yet unevenly adopted strategy among SMEs in developing economies, where infrastructural disparities between urban and rural areas continue to hinder equitable entrepreneurial growth. This study aims to examine the influence of mobile marketing intensity and geographical location on entrepreneurial success among small and medium-sized enterprises (SMEs) in Uzbekistan, with particular attention to urban–rural disparities. Despite rapid growth in business formation, many enterprises face challenges in achieving sustainable growth and competitive performance due to limited digital adoption and infrastructural constraints. Drawing on Technology Acceptance Theory (TAM), this research posits that entrepreneurs’ perceptions of the usefulness and ease of use of mobile marketing shape its effectiveness in enhancing business outcomes. Using a quantitative survey approach, data were collected from 100 SMEs (50 urban, 50 rural) via Google Forms. Mobile Marketing Intensity (MMI) and Entrepreneurial Success Index (ESI) were measured using Likert scales, while geographical location was coded as a binary variable. Data analysis employed multiple linear regression to assess the direct effects of MMI and location on ESI. Results indicate that mobile marketing intensity has a positive and significant effect on entrepreneurial success, and that urban enterprises outperform rural enterprises due to superior infrastructure, connectivity, and access to resources. This study contributes to the literature by highlighting the strategic role of mobile marketing as a capability that enhances entrepreneurial outcomes in emerging-market contexts and demonstrates how geographical disparities shape its effectiveness. The findings provide actionable insights for policymakers and entrepreneurs seeking to leverage digital marketing to drive business growth across diverse regions.
