Abstract

The rapid advancement of Virtual Reality (VR) technology presents a timely opportunity to enhance spatial abilities—skills fundamental to success in various educational and professional domains. This study addresses the urgent need to understand how VR can be effectively utilized in educational contexts to support spatial skill development. Employing a Systematic Literature Review (SLR) methodology, this research synthesizes findings from 26 peer-reviewed studies published between 2013 and 2022, sourced from Scopus, ScienceDirect, and SAGE Journals. The objectives are threefold: (1) to assess the effectiveness of VR in improving spatial abilities, (2) to identify at least three key factors influencing VR’s impact, and (3) to examine how initial spatial ability levels affect learning outcomes. The findings reveal that VR significantly enhances spatial skills, particularly mental rotation, and is most beneficial for learners with initially low spatial ability. Furthermore, three primary factors affecting VR effectiveness are identified: the level of interactivity, task alignment with learning objectives, and user immersion. From an affective perspective, VR also increases learner motivation and engagement, driven by its immersive and realistic environment. This research contributes to the growing body of knowledge on educational technology by offering evidence-based insights into the conditions under which VR can be most effective. The findings hold practical implications for educators, curriculum designers, and technology developers aiming to design targeted interventions for spatial skill development using VR.

Abstract

Despite growing interest in Computational Thinking (CT) integration within STEM education, significant gaps remain—particularly regarding underrepresented college students, CT inclusion at the entry level, and limited teacher preparation for CT integration. This study addresses these gaps by examining how educators’ professional experiences influence their attitudes and practices related to CT in STEM contexts. It also underscores the urgent need for empirical evidence to navigate the tension between generalized critical thinking frameworks and the unique demands of scientific representations in instructional planning. To map the development and current landscape of CT+STEM research, a bibliometric analysis was conducted on literature published between 1978 and 2023. The analysis reveals a consistent annual growth rate of 7.22% in the CT+STEM domain, encompassing 241 publications across 127 scholarly sources. The study identifies key authors, institutions, and influential works, while also visualizing global collaboration patterns and thematic trends in the field. This research contributes to the advancement of CT+STEM by providing a comprehensive overview of its evolution, highlighting areas of strength and underexplored dimensions. Although the study is quantitative in nature and acknowledges limitations such as potential database bias, it lays a foundation for future inquiry into qualitative methodologies, pedagogical strategies, and inclusive practices. The findings hold significant implications for educational policy, workforce development, and digital-age problem-solving, and call for deeper exploration into the pedagogical and sociocultural dynamics that shape effective CT+STEM integration.
