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

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’

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

Although improved water supply and distribution are two of the great engineering achievements of the 20th century, the National Academy of Engineering lists "access to clean water" as one of its current worldwide challenges.*Addressing this challenge requires inspiring the next generation of scientists, engineers, and citizens to tackle clean water issues. In the United States, this challenge is generally part of the civil infrastructure of drinking water and wastewater treatment systems. However, this infrastructure is aging and needs investment and enhancement, requiring political and

An educated citizenry that participates in and contributes to science technology engineering and mathematics innovation in the 21st century will require broad literacy and skills in computer science (CS). School systems will need to give increased attention to opportunities for students to engage in computational thinking and ways to promote a deeper understanding of how technologies and software are used as design tools. However, K-12 students in the United States are facing a broken pipeline for CS education. In response to this problem, we have developed the Scalable Game Design curriculum

New technologies are increasingly giving science teachers the ability to access and customize science lessons. However, there is substantial debate in the literature about whether and under what conditions teacher customization benefit student learning. In this study, we examined teacher customization of inquiry-based science lessons from an online lesson portal. We found that students who completed teacher-customized lessons had greater improvements in science content understanding than students who completed non-customized lessons. To expand upon this finding, we examined four case studies

Considering that the absence of measurement error in research is a rare phenomenon and its effects can be dramatic, we examine the impact of measurement error on propensity score (PS) analysis used to minimize selection bias in behavioral and social observational studies. A Monte Carlo study was conducted to explore the effects of measurement error on the treatment effect and balance estimates in PS analysis across seven different PS conditioning methods. In general, the results indicate that even low levels of measurement error in the covariates lead to substantial bias in estimates of

The primary purpose of this study was to examine the ways in which a 12-week afterschool science and engineering program affected middle school students' motivation to engage in science and engineering activities. We used current motivation research and theory as a conceptual framework to assess 14 students' motivation through questionnaires, structured interviews, and observations. Students reported that during the activities they perceived that they were empowered to make choices in how to complete things, the activities were useful to them, they could succeed in the activities, they enjoyed

Curriculum and instructional strategies that are personally meaningful are key to engaging students from diverse ethnic and cultural backgrounds.A “one size fits all” approach to curriculum development does not always translate to accessible education for many students, particularly in science,technology, engineering, and mathematics (STEM) education. Meaningful and relevant activities that demonstrate a direct application of STEM to the lives of students or their communities can increase engagement in STEM. Specifically, students are more likely to relate to instructional activitiesthat draw
