The Effect of Networked Learning Model and Self-Efficacy on the Performance of Informatics Education Students in an Online Learning Environment

Adlia Alfiriani — 2024-10-23

Online learning is becoming very popular nowadays in higher education, this is due to the increasing use of digital technology and the internet, the need to increase student affordability. The learning network model has been developed as an effective learning design in online learning which can be the right solution for. However, currently no empirical evidence has been found regarding the role of the learning network model, especially as moderated by self-efficacy. The aim of this research is to determine the role of the learning network model and self-efficacy on the performance of informatics education students in an online learning environment. The research design used was semi-experimental with a 2x2 factor. A total of 109 informatics education students for learning evaluation subjects were then divided into two groups, namely experimental and control. The research results show that the learning network model and self-efficacy have a significant effect on student performance in the cognitive aspect, while there is no significant effect in the psychomotor aspect. Other factors This can occur because there are other factors that can support the achievement of student skills besides learning self-efficacy.

Highlights:

Significant Impact: The learning network model and self-efficacy significantly enhance cognitive performance in online learning environments.
Limited Effect: No significant impact was found on psychomotor skills, indicating other factors influence skill development.
Research Design: A semi-experimental 2x2 factor design was utilized with 109 informatics education students to assess the variables.

Topographic and Geodetic Survey for Samarkand's Administrative Boundaries

Obidova D. D — 2024-10-31

General Background: Administrative and territorial boundary delineation is vital in the effective governance and economic planning of urban regions globally, with digital technologies increasingly integrated into these processes for accuracy and efficiency. Specific Background: In Uzbekistan, the city of Samarkand’s administrative boundaries are undergoing significant realignment as part of a broader initiative to incorporate strategic urban centers and enable digital land management across administrative zones. Knowledge Gap: Existing methods lack precise integration with digital geospatial frameworks, leaving a gap in high-resolution topographic data essential for clear administrative delineation. Aims: This study seeks to develop and apply an accurate, digitally supported methodology for determining the boundaries of Samarkand's administrative units using advanced geodetic and topographic techniques. Results: By utilizing the CREDO DAT program, this study achieved precise boundary coordinates through the automated processing of survey points, and further analysis was conducted using the Panorama program for detailed map orientation. Novelty: This research presents a unique approach by integrating CREDO DAT with geospatial tools in administrative boundary demarcation, enabling accurate and reproducible results that surpass traditional methods in efficiency and scalability. Implications: The findings support the strategic planning of Samarkand’s infrastructure and resource allocation while also laying the groundwork for applying similar methodologies in other urban regions, advancing Uzbekistan’s digital transformation efforts in land management.
Highlights:

Digital tools enhance accuracy in administrative boundary mapping.
CREDO DAT and Panorama software streamline data processing for precise mapping.
This method supports effective urban planning and resource management in Samarkand.
