Effect of Revit and AutoCAD Softwares on Students' 3D Skill Performance in Modelling Building Drawings in Technical Colleges in Akwa Ibom State

Abstract

The purpose of this study was to determine the effect of Revit and AutoCAD software on
students'3D skill performance in modeling building drawings in Technical Colleges in AkwaIbom State. Three specific objectives, there research questions, three null hypothesis guided
the study. The study adopted the quasi-experimental design of non-randomized pre-test, posttest control group. The population of the study was 320 students comprised all building
construction students in senior technical three in the six technical colleges in Akwa Ibom State.
The sample consists of 134 Senior Technical lll building and construction work students
Purposive sampling technique was used to select the two schools from six technical colleges in
the study. From the two schools, two intact classes were assigned to treatment and control
groups. Data for the study were collected during the practical sessions of the instruction using
the researcher developed instrument called 'Building Drawing Modeling Skilled
Checklist'(BDMSC) The instrument developed was face and content validated by three experts
in the faculty of education. The scores obtained from the trial-test were subjected to item
analysis to determine the reliability index of the instrument. Reliability co-efficient of the
instrument was determined using Cronbach Alpha method. The result showed reliability coefficient of 0.87. The data collected were analyzed using mean, standard deviation to answer
the research questions. Analysis of Covariance (ANCOVA) at 0.05 probability level was used
to test hypothesis. The finding revealed that the use of Revit and AutoCAD has a significant
effect on 3D skill performance in Modeling Building Drawings. The study shows that students
taught modeling building drawing using Revit software performed better than students taught
using AutoCAD.
