Teaching students how to think like scientists is a critical but challenging goal in biochemistry education. The Biochemistry Authentic Scientific Inquiry Lab (BASIL) initiative was conceived by Dr Paul Craig from the Rochester Institute of Technology and is led by colleagues across multiple institutions. They have developed an innovative curriculum that transforms traditional cookbook-style laboratory courses into authentic research experiences, also known as a Course-based Undergraduate Research Experience (CURE). By investigating real proteins with unknown functions, students learn essential scientific skills while expanding our knowledge of protein biochemistry.

Undergraduate research experiences (UREs) significantly enhance students’ critical thinking, problem-solving, and teamwork skills, and foster pathways to graduate studies. Social science laboratory-based undergraduate research experiences (LUREs) offer similar benefits with more impact on the understanding of the research process and influence career direction. As online undergraduate programs increase, research opportunities must adapt to incorporate otherwise excluded remote students. This study employs an expert panel method that collects insights from 22 experienced lab leaders around meeting the substantial challenges of mentoring online students in social science lab groups. Through thematic analysis, four key challenges and proposed solutions to enable remote undergraduate students to successfully engage in research labs were identified. These solutions offer practical guidance to improve inclusivity and accessibility for online learners.more » « less

Additive manufacturing (AM) is prevalent in academic, industrial, and layperson use for the design and creation of objects via joining materials together in a layer upon layer fashion. However, few universities have an undergraduate course dedicated to it. Thus, using NSF IUSE support [grant number redacted for review] from the Exploration and Design Tier of the Engaged Student Learning Track, this project has created and implemented such a course at three large universities: Texas Tech (a Carnegie high research productivity and Hispanic Serving Institution), Kansas State (a Carnegie high research productivity and land grant university) and California State, Northridge (the largest of all the California State campuses and highly ranked in serving underprivileged students). Our research team includes engineering professors and a sociologist trained in assessment and K-12 outreach to determine the effects of the course on the undergraduate and high school students. We are currently in year two of the three years of NSF support. The course focuses on the fundamentals of the three families of prevailing AM processes: extrusion-based, powder-based, and liquid-based, as well as learning about practical solutions to additive manufacturing of common engineering materials including polymers, metals and alloys, ceramics, and composites. It has a lecture plus lab format, in that students learn the fundamentals in a classroom, but then apply and broaden their knowledge in lab projects and independent studies. Additionally, as outreach, we host field trips from local high schools during which the undergraduates give presentations about discrete AM skills, then lead the high school students through a lab project focused on those skills. This creates a pipeline of knowledge about AM for younger students as well as an opportunity for undergraduates to develop leadership and speaking skills while solidifying their knowledge. We are also in the process of uploading videos and lab projects to an online Google Classroom so that those with access to 3D printers in other areas can learn online for free. We are also self-publishing an accompanying textbook and lab manual. Beyond the course itself, one of the innovations of our project is the assessment strategy. For both undergraduates and high school students, we have been able to collect content area knowledge both before and after the class, as well as information about their attitudes towards engineering and self-efficacy beliefs. This has been particularly illuminating in regards to subgroups like women and students of color. Our research questions include: i) what is the knowledge growth about AM during this course? ii) does this differ by university? iii) does this differ by gender or race? iv) what are the best ways to make this course portable to other universities? Preliminary results indicate a statistically significant improvement in knowledge for all students. This was particularly true for women, which may indicate the promise of AM courses in decreasing the female dropout rate in engineering. Attitudes towards engineering and self-efficacy perceptions also differed after the class, but in varying ways by demographic subgroups and university. This will be explored more in the paper.more » « less

ABSTRACT Undergraduate research experiences (UREs) cultivate workforce skills, such as critical thinking, project management, and scientific communication. Many UREs in biophysical research have constraints related to limited resources, often resulting in smaller student cohorts, barriers for students entering a research environment, and fewer mentorship opportunities for graduate students. In response to those limitations, we have created a structured URE model that uses an asynchronous training style paired with direct-tiered mentoring delivered by peers, graduate students, and faculty. The adaptive undergraduate research training and experience (AURTE) framework was piloted as part of the Brown Experiential Learning program, a computational biophysics research lab. The program previously demonstrated substantial increases and improvements in the number of students served and skills developed. Here, we discuss the long-term effectiveness of the framework, impacts on graduate and undergraduate students, and efficacy in teaching research skills and computational-based biophysical methods. The longitudinal impact of our structured URE on student outcomes was analyzed by using student exit surveys, interviews, assessments, and 5 years of feedback from alumni. Results indicate high levels of student retention in research compared with university-wide metrics. Also, student feedback emphasizes how tiered mentoring enhanced research skill retention, while allowing graduate mentors to develop mentorship and workforce skills to expedite research. Responses from alumni affirm that workforce-ready skills (communicating science, data management, and scientific writing) acquired in the program persisted and were used in postgraduate careers. The framework reinforces the importance of establishing, iterating, and evaluating a structured URE framework to foster student success in biophysical research, while promoting mentorship skill training for graduate students. Future work will explore the adaptability of the framework in wet lab environments and probe the potential of AURTE in broader educational contexts.more » « less

This NSF IUSE project is on the Exploration and Design Tier and the Engaged Student Learning Track. It is aimed at better preparing the country’s professional workforce in the renaissance of U.S. skilled manufacturing by creating new personnel proficient in additive manufacturing (AM). AM is mainstream; it has the potential to bring jobs back to the U.S. and add to the nation’s global competitiveness. AM is the process of joining materials to make objects from 3D data in a layer upon layer fashion. The objectives are to develop, assess, revise, and disseminate an upper division course and laboratory, “Additive Manufacturing,” and to advance undergraduate and K-12 student research and creative inquiry activities as well as faculty expertise at three diverse participating universities: Texas Tech, California State-Northridge, and Kansas State. This research/pedagogical team contains a mechanical engineering professor at each university to develop and teach the course, as well as a sociologist trained in K-12 outreach, course assessment, and human subjects research to accurately determine the effects on K-12 and undergraduate students. The proposed course will cover extrusion-based, liquid-based, and powder-based AM processes. For each technology, fundamentals, applications, and advances will be discussed. Students will learn solutions to AM of polymers, metals, and ceramics. Two lab projects will be built to provide hands-on experiences on a variety of state-of-the-art 3D printers. To stimulate innovation, students will design, fabricate, and measure test parts, and will perform experiments to explore process limits and tackle real world problems. They will also engage K-12 students through video demonstrations and mentorship, thus developing presentation skills. Through the project, different pedagogical techniques and assessment tools will be utilized to assess and improve engineering education at both the undergraduate and K-12 levels through varied techniques: i) undergraduate module lesson plans that are scalable to K-12 levels, ii) short informational video lessons created by undergraduates for K-12 students with accompanying in-person mentorship activities at local high schools and MakerSpaces, iii) pre- and post-test assessments of undergraduates’ and K-12 participating students’ AM knowledge, skills, and perceptions of self-efficacy, and iv) focus groups to learn about student concerns/learning challenges. We will also track students institutionally and into their early careers to learn about their use of AM technology professionally.more » « less
