This research examines the effect of the blended project-based learning (PjBL) model and creative thinking ability on engineering students' drawing learning outcomes. Using a pre and post-test quasi-experimental design, the research included a sample of 80 students from two different classes at the Faculty of Engineering, UNIMED, North Sumatra,…

Research on self-efficacy has provided evidence that it is a moderating factor that positively impacts students' choices to pursue and persist in engineering. Engineering graphics is seen as the preferred method of communication for the profession, yet to date no instrument is available that measures students' self-efficacy as it relates to…

Modeling activities enriched with 3D printers are effective in providing teachers with the skills they should have and in using the technology in mathematics education. In this regard, in the present study, ten-week modeling activities were carried out with 3D printers that are widely used in different fields along with educational environments…

We explored how beginning-level interior architecture students develop skills to create mental visualizations of three-dimensional objects and environments, how they develop their technical drawing skills, and whether or not physical and computer generated models aid this design process. We used interviews and observations to collect data. The…

Designers often collaborate to explore creative ideas, especially during the early stages of conceptual design, and their mental models, as the framework of design tasks, greatly influence the collaborative sketching process. Such models have multiple kinds of differences and each kind might have unique effects, yet previous studies analyzed these…

Results from a number of studies indicate that the use of drafting models can positively influence the spatial visualization ability for engineering technology students. However, additional variables such as light, temperature, motion and color can play an important role but research provides inconsistent results. Considering this, a set of 5…

A quasi experimental study was done to determine significant positive effects among three different types of visual models and to identify whether any individual type or combination contributed towards a positive increase of spatial visualization ability for students in engineering technology courses. In particular, the study compared the use of…

Spatial abilities have been used as a predictor of success in several engineering and technology disciplines (Strong & Smith, 2001). In engineering graphics courses, scores on spatial tests have also been used to predict success (Adanez & Velasco, 2002; Leopold, Gorska, & Sorby, 2001). Other studies have shown that some type of…

Engineering graphics has historically been viewed as a challenging course to teach as students struggle to grasp and understand the fundamental concepts and then to master their proper application. The emergence of stable, fast, affordable 3D parametric modeling platforms such as CATIA, Pro-E, and AutoCAD while providing several pedagogical…

The effects of four different instructional formats (orthographic drawing, isometric drawing, physical model, and isometric and physical model together) on learning outcomes and strategies for spatial tasks were studied with 40 secondary students. Findings indicate that physical models cause the least extraneous cognitive load. (SLD)

Development of the Building Description System (BDS) was undertaken to explore use of the computer to construct models of complex physical systems. A fundamental goal of this work is a computer system capable of replacing drawings as the primary description for design and construction of buildings. This paper presents an overview of the database…

Presents a knowledge representation model that was designed for instructional decision making. Topics discussed include classification models for instructional design; artificial intelligence; semantic networks; natural language; and data models, including network and hierarchical models. An example is given of knowledge analysis for a secondary…
