Designing and Implementing an Elementary Science After School Field Experience

Publication

Field experiences provide an important opportunity for preservice teachers to observe and practice science instruction. Too often, insufficient time is allotted for elementary science instruction in the formal classroom. This paper outlines the opportunities and lessons learned from an after school field experience where preservice elementary teachers worked in two-person teams with a classroom mentor teacher at local elementary schools and community centers to deliver two science lessons per week during an elementary science methods course. Multiple evidences of success are presented at the

Computing with a Community Focus: Outcomes from an App Inventor Summer Camp for Middle School Students

Publication

This paper describes the design and evaluation of a one-week App Inventor summer camp for middle school students with an explicit focus on addressing local community needs. The community focus of the camp was designed to appeal to a broad range of students. We conducted an in-depth interview study to examine its impact on students' attitudes and perceptions, and supplemented this with results from project evaluation. Our results indicate that students had positive experiences in learning and creating real apps for solving community problems. Focusing on local community needs can also help to

Gender Differences in Conceptualizations of STEM Career Interest: Complementary Perspectives from Data Mining, Multivariate Data Analysis and Multidimensional Scaling

Publication

Data gathered from 325 middle school students in four U.S. states indicate that both male (p < .0005, RSQ = .33) and female (p < .0005, RSQ = .36) career aspirations for being a scientist are predictable based on knowledge of dispositions toward mathematics, science and engineering, plus self-reported creative tendencies. For males, strong predictors are creative tendencies (beta = .348) and dispositions toward science (beta = .326), while dispositions toward mathematics is a weaker (beta = .137) but still a significant (p < .05) predictor. For females, significant (p < .05) predictors ordered

What Makes for Powerful Classrooms, and How Can We Support Teachers in Creating Them? A Story of Research and Practice, Productively Intertwined

Publication

This article and my career as an educational researcher are grounded in two fundamental assumptions: (a) that research and practice can and should live in productive synergy, with each enhancing the other, and (b) that research focused on teaching and learning in a particular discipline can, if carefully framed, yield insights that have implications across a broad spectrum of disciplines. This article begins by describing in brief two bodies of work that exemplify these two fundamental assumptions. I then elaborate on a third example, the development of a new set of tools for understanding and

Transformative Experience: An Integrative Construct in the Spirit of Deweyan Pragmatism

Publication

A sentiment held by Dewey and shared by other educators is that learning should enrich and expand everyday experience. However, this goal has not been a focus of research. In this article, I propose transformative experience as a construct capable of reflecting this goal and functioning as an empirical research construct. I discuss the theoretical grounding for this construct in the work of Dewey and define it in terms of three characteristics: (a) motivated use, (b) expansion of perception, and (c) experiential value. In doing so, I describe how transformative experience integrates current

Building the Foundational Skills Needed for Success in Work at the Human-Technology Frontier

The proliferation of new technologies has changed the way we live, learn, and work. Although the future of work is unclear, thought leaders, including the National Science Foundation (NSF), assert that artificial intelligence, the Internet of Things, robotics, and machine learning will be ubiquitous in tomorrow’s workplaces. This vision of the future includes a new machine age, where various technologies (sensors, communication, computation, and intelligence) will be embedded around, on, and in us; where humans will shape technology and technology will shape human interaction; and where

Modeling Protein Structure & Function: Pencil Transferase

Publication

The interrelationship of structure and function is a key theme of biology. One important example of this relationship involves how the three-dimensional shapes of proteins are related to the roles they play at the cellular level. The treatment of protein structure in many introductory textbooks, however, is cursory and focuses on the relationships among primary, secondary, tertiary, and quaternary structure without a clear link to how these levels of organization contribute to functional aspects of the protein. This short and engaging hands-on activity helps reinforce the connection between

The Emerging Role of Science Teachers in Fostering Stem Career Awareness

Publication

Understanding how high school students become aware of STEM career options, how educators can help students translate awareness into pursuit of STEM careers, and how to provide students with the support and skills they need to succeed, are crucial elements in ensuring the future of our STEM workforce. One important factor is the role that high school science teachers can play in fostering STEM career interest and awareness. As part of our study, we conducted interviews and focus groups with over 70 high school science teachers and other science and career education experts. Teachers’

Bioinformatics Education in High School: Implications for Promoting Science, Technology, Engineering, and Mathematics Careers

Publication

We investigated the effects of our Bio-ITEST teacher professional development model and bioinformatics curricula on cognitive traits (awareness, engagement, self-efficacy, and relevance) in high school teachers and students that are known to accompany a developing interest in science, technology, engineering, and mathematics (STEM) careers. The program included best practices in adult education and diverse resources to empower teachers to integrate STEM career information into their classrooms. The introductory unit, Using Bioinformatics: Genetic Testing, uses bioinformatics to teach basic

SciGirls Strategies is a National Science Foundation–funded project led by Twin Cities PBS (TPT) in partnership with St. Catherine University, the National Girls Collaborative, and XSci (The Experiential Science Education Research Collaborative) at the University of Colorado Boulder’s Center for STEM Learning. This three-year initiative aims to increase the number of high school girls recruited to and retained in fields where females are traditionally underrepresented: technical science, engineering, technology, and math (STEM) pathways. We seek to accomplish this goal by providing career and
