Can 3-Dimensional Visualization Enhance Mental Rotation (MR) Ability?: A Systematic Review
(2023-01-01) Piri Z.; Cagiltay K.
This review aims to explore how mental rotation (MR) ability is enhanced using three-dimensional visualization. Earlier mental rotation trainings entailed two-dimensional drawings and representations that lack the necessary visual information present in three-dimensional spatial representations. Therefore, this review limits its scope to three-dimensional visualization-based training interventions using monoscopic, stereoscopic, and autostereoscopic 3-D displays as well as augmented and mixed reality displays to understand what representational fidelity can offer to improve mental rotation ability. ScienceDirect, Eric, SpringerLink and Web of Science databases were searched. A total of 51 articles were selected for the review. Results indicated that all studies but one found that 3-D visualization-based training significantly improved MR ability regardless of the technology and target group used. Allowing views from multiple angles was the most prominent affordance of 3-D visualization for MR training. The results also tentatively suggest that 3-D MR training is more effective than 2-D MR training. Furthermore, these systems may benefit females more than males while not imposing a greater cognitive load than 2-D training. The degree of immersion positively affects MR performance.

Open Educational Resources in Turkey
(2020-01-01) Tisoglu S.; Kursun E.; Cagiltay K.
The purpose of this study is to present an Open Educational Resources (OER) landscape to the extent of the development (infrastructure, policy, stakeholders and license), integration (curriculum and teaching methodology and resources) and the impact (outcomes) on educational context where each three section holds their sub-sections to provide a comprehensive picture of the OER movement in Turkey. Through the growing trend of movements related to access to, quality of and equity of education, OERs play an important role to reshape the teaching and learning experiences by transforming education in the world. Therefore, beyond the state of the art of OERs in Turkey, how Turkey contributes to this movement is important to share timely. As beginning with the timeline of the initiatives in Turkey, this chapter comprises of three sections within its sub-sections, extent of development, integration and the impact of OERs on education.
