Introducing engineering in elementary education: A 5-year study of teachers and students

Heidi A. Diefes‐Dux

British Journal of Educational Technology Vol. 46, No. 5 (Sep 01, 2015) pp. 1015–1019

Engineering, when integrated into K-12 education, may offer a number of potential student learning and future success benefits. In a 5-year study, four cohorts of elementary teachers of grades 2 to 4 in a single US school district were provided with ...

First-Year Engineering Students' Portrayal of Engineering in a Proposed Museum Exhibit for Middle School Students

Irene B. Mena; Heidi A. Diefes-Dux

Journal of Science Education and Technology Vol. 21, No. 2 (April 2012) pp. 304–316

Students' perceptions of engineering have been documented through studies involving interviews, surveys, and word associations that take a direct approach to asking students about various aspects of their understanding of engineering. Research on...

Models for early prediction of at-risk students in a course using standards-based grading

Farshid Marbouti; Heidi A. Diefes-Dux; Krishna Madhavan

Computers & Education Vol. 103, No. 1 (December 2016) pp. 1–15

Using predictive modeling methods, it is possible to identify at-risk students early and inform both the instructors and the students. While some universities have started to use standards-based grading, which has educational advantages over common...
