Most researchers and public health officials would agree that the causes and consequences of obesity are complex and multi-faceted. However, curricula designed to address these complexities are limited and often guided by a single discipline. The purpose of the Transdisciplinary Obesity Prevention Research Sciences (TOPRS) program was to develop a...

There is a need for innovative approaches in the classroom to increase student preparedness to address and solve some of today’s complex social problems. Interdisciplinary courses can be one way to accomplish this. This is an exploratory study to examine if an interdisciplinary web-based video series is associated with improvements in interdiscipli...

Transformation of research in all biological fields necessitates the design, analysis and, interpretation of large data sets. Preparing students with the requisite skills in experimental design, statistical analysis, and interpretation, and mathematical reasoning will require both curricular reform and faculty who are willing and able to integrate...

The Transdisciplinary Obesity Prevention Research Sciences Program (TOPRS) is an applied research methods curriculum for undergraduates on the causes and consequences of childhood obesity that has been developed by a multidisciplinary team from the University of Illinois at Urbana‐Champaign, Purdue University, and California State University‐Fresno...

This study examined to what extent a curriculum module that uses animal and human health scientists and science concepts to portray science and scientists in a relevant and authentic manner could enhance elementary students' aspiration for science careers, attitudes to science, positive perceptions of scientists, and perceived relevance of science....

This qualitative study examines the process of student learning in a small-business experiential internship program that pairs highly qualified undergraduates with local small or start-up companies. The Cognitive Apprenticeship model developed by Collins et al (1991) was used to conceptualize students' reported experiences. The results revealed tha...

Although virtual field trips are becoming popular, there are few empirical studies of their impacts on student outcomes. This study reports on a meta-analytic evaluation of the impact of a virtual field trip on student perceptions of scientists. Specifically, the study examined the summary effect of zipTrips broadcasts on evaluation participants’ p...

This study examines the development and implementation of a survey-based instrument assessing the effectiveness of a course redesign initiative focused on student centeredness at a large midwestern university in the United States. Given the scope of the reform initiative under investigation in this study, researchers developed an instrument called...

Pedagogical strategies increasing rely on technology as a way to address challenges facing the contemporary higher education classroom. This study investigated the use of a tool designed with the specific purpose of student engagement in a large classroom. The tool allows students to post to a community based discussion in a manner similar to a Twi...

The current study examines the trajectories of student perceived gains as a result of time spent in an undergraduate research experience (URE). Data for the study come from a survey administered at three points over a 1-yr period: before participation in the program, at the end of a Summer segment of research, and at the end of the year. Repeated-m...

Positive student outcomes of undergraduate research experiences (UREs) have been well documented, however, many studies have neglected the logical relationship among outcomes, the processes through which they are achieved, and the contextual and participant factors at play in UREs. This study uses structural equation modeling to explore these issue...

Workforce development strategies to educate, inform, and diversify the veterinary profession of the future must begin with children in elementary school. This article provides a description of the Fat Dogs and Coughing Horses program, which takes a multifaceted approach toward informing young students, beginning in first grade, about the interestin...

This qualitative study examines the process of student learning in a small-business experiential internship programme that pairs highly qualified undergraduates with local small or start-up companies. The Cognitive Apprenticeship model developed by Collins et al (1991) was used to conceptualize students' reported experiences. The results revealed t...

Extant and emerging literature on undergraduate research experiences (UREs) focuses on the identification of their benefits to student participants. However, a notable limitation in these studies results from little or no examination of the processes through which UREs influence student career decisions and education aspirations. This study offers...

Participant perceptions of program effectiveness and impact are undoubtedly a popular focus of Extension program evaluations. However, the effects of participants' characteristics and contextual variables on program perceptions and how the resulting data can be used for program improvement are less explored in evaluation studies. Using data from th...

Cancer prevention is a broad field that crosses many disciplines; therefore, educational efforts to enhance cancer prevention research focused on interdisciplinary approaches to the field are greatly needed. In order to hasten progress in cancer prevention research, the Cancer Prevention Internship Program (CPIP) at Purdue University was designed t...

Physical field trips to scientists’ work places have been shown to enhance student perceptions of science, scientists and science careers. Although virtual field trips (VFTs) have emerged as viable alternatives (or supplements) to traditional physical fieldtrips, little is known about the potential of virtual field trips to provide the same or simi...

In the last twenty years, research about science learning in informal contexts such as museums, science centers, zoos and aquariums has proliferated. Many studies have created detailed descriptions of learning as it occurs in informal contexts. Science education researchers have defined learning in several different ways. The selection of a concept...

Learning about the nature of science involves learning about science, its goals, methods, products, and practitioners. As university students progress through their studies, what are they learning about science? Several studies have attempted to answer this question, but none have examined the ideas of atmospheric science students. We discuss the r...
