Organizational Unit
Political Science
The Department of Political Science has been a separate department in the College of Liberal Arts and Sciences (formerly the College of Sciences and Humanities) since 1969 and offers an undergraduate degree (B.A.) in political science, a graduate degree (M.A.) in political science, a joint J.D./M.A. degree with Drake University, an interdisciplinary degree in cyber security, and a graduate Certificate of Public Management (CPM). In addition, it provides an array of service courses for students in other majors and other colleges to satisfy general education requirements in the area of the social sciences.
Organizational Unit
Statistics
As leaders in statistical research, collaboration, and education, the Department of Statistics at Iowa State University offers students an education like no other. We are committed to our mission of developing and applying statistical methods, and proud of our award-winning students and faculty.
Organizational Unit
Agricultural and Biosystems Engineering

Since 1905, the Department of Agricultural Engineering, now the Department of Agricultural and Biosystems Engineering (ABE), has been a leader in providing engineering solutions to agricultural problems in the United States and the world. The department’s original mission was to mechanize agriculture. That mission has evolved to encompass a global view of the entire food production system–the wise management of natural resources in the production, processing, storage, handling, and use of food fiber and other biological products.

History
In 1905 Agricultural Engineering was recognized as a subdivision of the Department of Agronomy, and in 1907 it was recognized as a unique department. It was renamed the Department of Agricultural and Biosystems Engineering in 1990. The department merged with the Department of Industrial Education and Technology in 2004.

Abstract

In the past ten years, engineering classrooms have seen an exponential growth in the use of technology, more than during any other previous decade. Unprecedented advancements, such as the advent of innovative gadgets and fundamental instructional alterations in engineering classrooms, have introduced changes in both teaching and learning. Student learning in introductory, fundamental engineering mechanics (IFEM) courses, such as statics of engineering, mechanics of materials, dynamics, and mechanics of fluids, as in any other class, is influenced by the experiences students go through in the classroom. Thus, bold new methodologies that connect science to life using student-centered approaches and scaffolding pedagogies need to be emphasized more in the learning process. This study is aimed to gain insight into the role of student-centered teaching, particularly the implementation of scaffolding pedagogies into IFEM courses. This study also attempts to contribute to the current national conversation in engineering education of the need to change its landscape—from passive learning to active learning. Demographic characteristics in this study included a total of 3,592 students, of whom 3,160 (88.0%) are males and 432 (12.0%) are females, over a period of six years, from 2007 to 2013. The students’ majors included aerospace engineering, agricultural engineering, civil engineering, construction engineering, industrial engineering, materials engineering, and mechanical engineering. Results of the study, as tested using a general linear univariate model analysis, indicated that overwhelmingly the type of class in statics of engineering is a significant predictor of student “downstream” performance in tests measuring their knowledge of mechanics of materials. There is a statistically significant difference in students’ performance in mechanics of materials depending on whether they were taught passively using the teacher-centered pedagogy or taught actively using the student-centered pedagogy in statics of engineering. Mechanics of materials is commonly the next immediate course, or a downstream course, following statics of engineering.
