This case study focuses on modeling and analyzing the practices concerning the staffing of the immigration agency at the Island of Tropical Paradise International Airport (ITPIA), which is responsible for processing arriving passengers into the country. Immigration at ITPIA has engaged you to understand the trade-offs between the number of…

This study aimed to investigate students' perceptions of engineers and how they vary by grade level and gender. This study proposes an approach to understanding the Chinese students' perceptions of engineers and the interest preference of middle school students in the way of graphic analysis and questionnaire. This descriptive study incorporated a…

Background: Research in engineering education has highlighted the importance of identity and motivation for a number of student outcomes, including persistence. However, these constructs have often been studied separately, despite theorized and demonstrated connections between students' identity and motivation in other fields. Purpose/Hypothesis:…

Background: Spatial ability is significantly related to performance in engineering education, and problem-solving, an activity that is highly relevant to engineering education, has been linked to spatial ability. Purpose/Hypothesis: This study investigated the following question--To what extent is spatial ability related to problem-solving among…

Background: Many engineering students fail to proceed through required prerequisite mathematics courses. Since these courses strongly influence engineering student attrition, we should examine to what degree these courses truly serve as prerequisites for following engineering coursework. Purpose/Hypothesis: We examined two research questions:…

A case study of regression analysis based on modeling Gilliland's correlation was described for use in a computational methods course. The case study uses a familiar example to train students in nonlinear least squares regression and to use standardized residual plots for model assessment. Previously published equations for Gilliland's correlation…

This paper presents details of remodelling of an engineering design subject to enhance students' learning outcome. The subject is offered for second year mechanical engineering undergraduates in the first semester of the academic year. The basic objective of the subject is to introduce the engineering design practice and to build up the essential…

In this paper, we describe our solution to predict student STEM career choices during the 2017 ASSISTments Datamining Competition. We built a machine learning system that automatically reformats the data set, generates new features and prunes redundant ones, and performs model and feature selection. We designed the system to automatically find a…

The Design Studio is an academic makerspace, housed in the Mechanical Engineering Department at University of Delaware, that was co-developed through a multi-year, grassroots effort by the department and its undergraduate study body. It originated in 2012 in a small, under-utilized study room and evolved in stages into its present form as a 5,500…

Literature indicated that attitude toward programming, programming self-efficacy, gender, and students' department was related to achievement in computer programming. However, there is a need for further studies investigating to what extent these factors explain programming achievement in a model. This study aimed to investigate the effects of…

In this paper, we present three types of activity that we have observed during students' free exploration of a software called "Algodoo," which allows students to explore a range of physics phenomena within the same digital learning environment. We discuss how, by responding to any of the three activity types we identify in the students'…

This study aims to improve collaboration in thinking, pairing, and sharing of students in energy conversion learning. This study experimented with the think pair and share (TPS) type of cooperative method to get improvements in terms of activity and cooperation. The procedure of the study adopted the classroom action research of the Kemmis &…

When students are unable to purchase a textbook because of rising prices and/or are unwilling to carry heavy textbooks, their education is compromised. Open educational resources (OERs) are gaining in popularity because they solve these problems by providing free study materials in electronic formats, but students from different backgrounds and…

New national science standards have elevated attention to student performance with a core set of science and engineering practices, yet guidance about how to assess these practices is only just emerging in the literature. This is particularly true for the set of engineering design-focused concepts and practices articulated in the Next Generation…

This study examines the research impact of gold open access (OA) journals in engineering and technology. A total of 37 gold route journals that request article processing charges (APC) and 66 other OA journals without APC (i.e., platinum OA) in the field were found in the Directory of Open Access Journals and used for the study. The publishers,…
