Abstract
Good spatial ability skills are an important component of an engineer’s ability to create and interpret engineering drawings, which is demanding in thinking, being a problem-solving process. The ability of an engineer to visualize in 3D is a cognitive skill that is attached to success in basic engineering drawing subjects. Engineering and technology education students need good spatial ability skills to understand several topics in basic engineering drawings like orthographic projection, axonometric drawing, sectional view, and hidden details drawings. This study aims at improving spatial ability skills using a solid pair model among first-year technical education students of Kaduna State College of Education Gidan Waya. A Quasi-experimental research design was used for the study, a standards pre and post-test were used to conduct a visualization transformation assessment to measure the students’ level of spatial ability skills. The study shows that after treatment using a solid pair model, the student without prior knowledge in basic engineering performed above average, likewise students with prior knowledge in the control and experimental group performed above average. The results indicate that a solid pair model was effective for improving spatial ability skills among first-year technical education students. This study implies to educators that there is need to appropriately enforce the use of a solid pair model for effective teaching and learning of basic engineering drawing. It is, therefore, affirmed that the use of a solid pair model in teaching basic engineering drawings should be enhanced with other teaching methods.

Highlights
Spatial ability skill is referred to as a trait in human intelligence which is a vital and very important fundamental skill in the engineering and technology field (Kok and Bayaga 2019)
The results revealed that student who had prior knowledge of basic engineering drawing from secondary school who were taught using the conventional method at post-test without treatment had a mean score 65.00 (SD = 13.093), the students who had prior knowledge and received treatment had a mean score 72.00 (SD = 19.235) while those without prior knowledge with a solid pair model treatment had a mean score of 59.33 (SD = 19.445)
The study is aimed at improving first-year NCE technical education students of Kaduna State College of Education Gidan Waya spatial ability skills in basic engineering drawing using a solid pair model
Summary
Spatial ability skill is referred to as a trait in human intelligence which is a vital and very important fundamental skill in the engineering and technology field (Kok and Bayaga 2019). Kösa and Karaku, (2010) stated that the ability to imagine a picture and manipulate the image of an object mentally is called spatial ability. According to Nagy-kondor (2007), the ability of an individual to manipulate or transform the patterns and image of an object into other shapes or form of arrangement is referred to as spatial ability. It deals with the manipulation of 2D or 3D objects mentally. The need for technical drawing becomes very demanding in such a way that, no production or manufacturing can be successfully done without a neat and detail drawing to show the relationship between components, joints, and other linkages
