Dynamic Desk Distribution Deviation Data (D5): Quantifying Lab Table Displacement to Support Efficient Classroom Circulation in Narrow, Row-Based Layouts

This research plan presents Dynamic Desk Distribution Deviation Data (D5), an independent, practitioner-led observational study designed to quantify the displacement of movable laboratory tables in a secondary-school Earth Science classroom. The proposed methodology uses removable floor reference markers and repeated measurements to document the magnitude, direction, and distribution of table displacement across instructional periods. A preliminary design targets 100 complete class-session observations, yielding 4,800 individual measurements, subject to pilot testing, feasibility, and applicable permissions. The study aims to identify spatial and temporal patterns, explore associations with classroom occupancy where supported, and evaluate practical approaches to maintaining classroom circulation in narrow, row-based layouts. The plan addresses measurement procedures, data quality, analysis, relevant scientific literature, intended outputs, and research limitations. This document presents the proposed research framework. It does not report completed data collection, empirical findings, or demonstrated effects on student learning or classroom safety.
