K-12 science teachers in the United States are encouraged to teach their students engineering. When incorporating engineering into their science curricula, teachers commonly either focus on: (1) engineering and lace science throughout; or (2) science and lace engineering throughout. This study explores middle school students' nature of engineering…

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…

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…

Students build up their STEM career interest based on their experiences. However, it remains unclear how students reflect on their STEM experiences in light of their understanding of STEM careers. This study aimed to explore how students relate their practices in STEM project-based learning (PBL) with their perceptions of scientists' and…

As part of a longitudinal study of the development and implementation of a middle school engineering design curriculum, we have used an occupational values subscale of the Assessing Men and Women in Engineering (AWE) project's Engineering version of the Core Survey for Middle School-Aged Participants to measure student occupational interest in…

This dissertation investigates the intersection of economics of innovation and human capital development to understand how to empower individuals and marginalized communities to be directed to innovation and STEM disciplines. The research focuses on three main chapters: Chapter 1 examines the effectiveness of an education program in teaching and…

With the growing adoption of the Next Generation Science Standards across the United States, elementary teachers are being called upon to incorporate engineering into their science instruction, creating a need for ways to help elementary teachers better understand what engineering is and how to accurately communicate it to students. The present…

The aim of this article is to report the results of an empirical study on adolescents' interest, self-efficacy, and vocational interest in technology and design. Following the expectancy-value model, we wanted to know how context-specific interest in technology and perceived self-efficacy in solving technical tasks are developed at lower…

Research suggests that, to narrow the gender gap in engineering, we should focus on helping young girls identify with engineering both because gendered attitudes emerge around kindergarten and because identity is more predictive than performance on persistence in the field. This qualitative study sought to understand the impact of collaborative…

Purpose: In 2017 and 2018, engineering applications and design process were given weight to with the updates carried out in the Physical Sciences Lesson Curriculum in Turkey. For the STEM education which is at the center of this update to reach its target, it is highly important that students accurately learn what engineers do, what their work…

Over the last fifteen years, engineering has made its way into science curriculum at all levels, elementary, middle, and high school. A need to analyze students' perception the field of engineering is warranted. Previous techniques for studying representations of scientists and build on what researchers in the science field have learned from…

The aim of this research was to present the Turkish adaptation of the survey for Middle-School Students' Attitudes toward Engineers and Scientists prepared by Lyons, Fralick and Kearn (2009) 32 items in a 5-point Likert type scale. The questionnaire was administered to 707 students receiving education in the fifth, sixth, seventh and eighth grades…

"Beyond Blackboards" is an inquiry-centered, after-school program designed to enhance middle school students' engagement with engineering through design-based experiences focused on the 21st Century Engineering Challenges. Set within a predominantly lowincome, majority-minority community, our study aims to investigate the impact of…

Students' knowledge about a profession influences their future decisions about careers. Research indicates that students tend to hold stereotypical views of engineers, which would hinder engineering as a career choice. The purpose of this study was to measure how participating in a week long engineering summer camp affected middle school students'…

The electric bicycle pusher is a legal bicycle trailer on wheels that can push a bicycle at speeds of up to 35 mph. People across the country are buying small electric cars that go no faster than that--and paying five times more than what one pays to make an electric bicycle pusher. In this article, the author provides some information on electric…
