The main goals of this study were to utilize an explicit instruction approach to develop mini modules to teach principles and techniques involved in spatial visualization skills to college engineering students. Mini modules were developed to enhance the spatial visualization skills of engineering students enrolled in the course Introduction to…

This study explores the relationship between collaborative dynamics, expressed through observed leadership behaviour, and skills. It is based on the mechanical design activity of six dyads of students (post-secondary vocational training), composed of 11 boys and one girl, who are improving an existing mechanical system. Actions are studied using…

Background: The importance of spatial abilities for individuals' success in science, technology, engineering, and mathematics (STEM) domains has been well established. Researchers have also emphasized the need to train engineering students in spatial ability. Although virtual reality (VR) offers prospects for training spatial abilities, research…

Engineering drawing is valuable in capturing geometric features, conveying engineering ideas, and creating a blueprint of the intended product. Engineering students usually perform orthographic projections, imagining a 3D situation and sketching its 2D representation. That requires imagination and mental visualization, determined by the learner's…

In 2013, the Next Generation Science Standards tasked science teachers to include more engineering processes in their instruction. Design thinking is one way this has been accomplished over the last decade, but other engineering characteristics might have an influence on how learners thinking through the design process. Using a pretest-posttest,…

Today's industry requires graduates of mechanical engineering expertise programs who have high creativity. The purpose of this study is to describe how the influence of spatial intelligence, adversity intelligence, on the creativity of vocational students of the mechanical engineering expertise program. The urgency of this research is as a basis…

This qualitative study was conducted to investigate the instructional practices employed by Engineering Graphics and Design (EGD) teachers to teach Isometric Drawing (ID). This enquiry was necessitated by the growing concern from subject advisors and teachers about the poor performance of learners in isometric drawing. In an attempt to meet the…

Insights on students' own authentic design practices--nascent design practices without much adult guidance--are crucial to informing responsive facilitation of engineering design tasks. This study unpacks how elementary students interpret teacher given information about a design task, and interact with each other and given resources, to traverse a…

The purpose of this study was to investigate the effect of augmented reality (AR) using a 3D app in a smartphone on students' learning outcomes and satisfaction in teaching angle measurement error to vocational high school students with different spatial ability. A quasi-experimental pretest/posttest was employed. There were 197 students from…

Effective spatial visualization and reasoning skills are often credited for students' success in science and engineering courses. However, students enrolled in these science courses are not always exposed to or trained properly on the best ways to utilize models to aid in their learning. Improving spatial visualization techniques with 3D models,…

Background: Spatial problem-solving is an essential skill for success in many engineering disciplines; thus, understanding the cognitive processes involved could help inform the design of training interventions for students trying to improve this skill. Prior research has yet to investigate the differences in cognitive processes between spatial…

The purpose of this study was to examine any differences in test scores between three different online versions of the Mental Cutting Test (MCT). The MCT was developed to quantify a rotational and proportion construct of spatial ability and has been used extensively to assess spatial ability. This test was developed in 1938 as a paper-and-pencil…

Spatial geometry is one of the multi-purpose fields of mathematics and is tightly linked to the development of mathematical and intellectual thinking. Spatial thinking is necessary in various areas of life such as civil engineering, mechanical engineering, interior design, graphic design and other. At present, teaching spatial geometry is mainly…

The purpose of this study is to investigate the effects of Augmented Reality (AR) intervention on students' spatial skills and academic achievement. The study was conducted in a freshman technical drawing course at Mechanical Engineering Department. An exploratory quasi-experimental method was used for the study. The study was conducted in two…

Spatial reasoning skills are a great predictor of students' Science, Technology, Engineering, and Mathematics (STEM) achievement and attainment. However, researchers have mainly viewed spatial reasoning skills as an internal cognitive process that is measured through the administration of psychometric testing and laboratory experiments. Further,…
